Detailed ways

The following describes exemplary embodiments of the present invention with reference to the accompanying drawings, which include various details of the embodiments of the present invention to facilitate understanding, and should be regarded as merely exemplary. Therefore, those of ordinary skill in the art should realize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Likewise, for clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

In order to miniaturize the volume of the physiological device, the device adopts a laminated structure design. As shown in FIG. 1, the housing 100 is constructed as a stack of upper housing 12, battery 14, and circuit from top to bottom. The board 16 and the lower casing 18, and the bottom surface of the lower casing is planned to face the skin of the human body, wherein the circuit board 16 has an upper surface and a lower surface, and physiological sensing elements are arranged on the circuit board, And the battery 14 is maintained above the circuit board 16. With this arrangement, the internal circuit connection configuration can be simplified to provide the largest battery volume, thereby achieving a compact size and sufficient power.

Since the battery volume is one of the most important factors that determine the size of the device, when choosing a battery, in addition to considering whether the size can meet the body curve at the desired location, it is also necessary to consider whether the power is sufficient for the use of the location. On demand, you can choose to use rechargeable batteries, such as lithium batteries, or disposable non-rechargeable batteries, all feasible.

In addition, an electrical contact component can be provided on the surface of the housing. As shown in the figure, one end of the electrical contact component 101 is mounted on the circuit board, and the other end is exposed on the bottom surface of the lower housing to form a power supply contact position for charging, Communication, or other electrical connections, etc., for example, can be used to charge rechargeable batteries, can be used to perform wired communication between the physiological device and the outside, for example, used to transmit information, set, etc., can also be used Performing the electrical extension of the physiological sensing element has the advantage of reducing the increase in volume caused by the provision of the connector. As for the detailed implementation, it will be described in the following content.

This kind of hardware configuration and electrical connection design makes the device housing present a column-like appearance, for example, columns with the same or different width/diameter up and down. As for the cross-section of the column, it can have various shapes, for example, Circles, squares, etc., can also have different top and bottom shapes, and can be changed according to actual needs, all of which belong to the scope of the present application.

Here, it should be noted that, in addition to being implemented as an upper housing and a lower housing, the housing can also be implemented to include other housing parts according to actual requirements, for example, the upper housing and the lower housing It is possible to set up an additional intermediate shell in between, so there is no limitation.

Next, please refer to FIG. 2, which illustrates a schematic circuit diagram of the physiological device according to the present application. When used for physiological signal acquisition, as is well known, in addition to the physiological sensing element and battery, a control unit is also required to control the operation of the overall device. The control unit includes at least a microcontroller/microprocessor, And pre-loaded with programs to control the communication between hardware components. The control unit can achieve signal transmission between different hardware components and external applications/external devices connected to the device, and also allows the behavior of the device to be programmed , In response to different operating conditions, and the microcontroller/microprocessor also uses an internal timer (not shown) to generate a time stamp or to control operations.

In addition, the control unit often includes an analog front-end (AFE) circuit for obtaining physiological signals to perform, for example, analog-to-digital conversion, amplification, filtering, and various other signals well known to those with ordinary knowledge in the field. The processing procedure, since these are all existing content, it is not repeated here.

In addition, the device may include a communication module, which may be implemented as a wired communication module, such as a USB interface, a UART interface, etc., or as a wireless communication module, such as Bluetooth, Bluetooth Low (BLE) Energy), Zigbee, WiFi, or other communication protocols to communicate with external devices. The external devices may include, but are not limited to, smart devices such as smart phones, smart bracelets, smart glasses, smart headsets, etc. Tablet computers, notebook computers, personal computers, and communication allows information to be exchanged between devices, as well as information feedback, remote control, and monitoring.

Alternatively, when a rechargeable battery is used, the device may have a charging module, such as an inductive charging circuit, or be charged through, for example, a USB interface.

In addition, the device may include an information providing interface, preferably an LCD or LED display element, to provide information to the user, for example, physiological information, statistical information, analysis results, stored events, operation modes, warning content , Progress, battery status, etc., are not restricted.

Furthermore, the device may include a data storage unit, preferably a memory, such as an internal flash memory, or a removable memory disk, to store the acquired physiological information.

In addition, when there is a wireless communication module, an antenna will be configured accordingly, and in order to place an antenna with a certain length in a tiny housing, the antenna can be arranged around the housing. For example, The antenna is laid out along the edge of the circuit board in the form of a printed circuit. The antenna can also be combined with the shell, for example, attached to the inside or outside of the shell, or embedded in the shell wall of the shell, or a separate wire The body is used as an antenna and is distributed along the inner surface of the housing, which is also a way to provide a sufficient length of antenna; alternatively, a chip antenna (Chip Antenna) can also be used without limitation.

Next, a description of the physiological sensing element is provided. One of the options is a light sensor, which refers to a sensor that has both a light-emitting source, such as an LED, and a light detector, such as a photodiode, which uses the principle of PPG (photoplethysmography) to emit light through a light-emitting source Entering the human tissue, the light penetrates the blood in the blood vessel or is reflected by the blood and is received by the photodetector. The blood physiological information is obtained by obtaining the volume change of the light, so it is generally called PPG signal; and Since the optical sensor obtains physiological information from the blood, its installation position can be any surface area with blood vessels, whether it is the head, the front or back of the body, the limbs, etc., all feasible without limitation.

Among them, the PPG signal will include a fast-moving component (AC component, AC component), which reflects the pulse wave generated by myocardial contraction transmitted through the artery, and a slow-moving component (DC component, DC component), which reflects the slower tissue blood volume. Changes, such as respiratory action (Respiratory Effort) (that is, the expansion and contraction of the chest and abdomen during breathing), the influence of sympathetic and parasympathetic nerve activity, and Mayer Waves, etc.; in addition, by analyzing PPG signals Physiological information such as blood vessel hardness and blood pressure can also be obtained. Furthermore, according to physiological experiments, the PPG pulse wave can be analyzed in the frequency domain to obtain the harmonic resonance between the organs and the heart rate, so the pulse wave heart rate can be obtained. Harmonic resonance distribution is used in the diagnosis of Chinese medicine and the monitoring of human blood circulation. For example, the liver and liver meridians are related to the first harmonic of the heartbeat frequency, the kidneys and kidney meridians are related to the second harmonic of the heartbeat frequency, and the spleen and spleen meridians The third harmonic of the heartbeat frequency is related, the fourth harmonic of the heartbeat frequency of the lungs and lungs is related, and the fifth harmonic of the heartbeat frequency of the stomach and stomach is related.

Generally speaking, the blood physiological information that can be obtained varies according to the type and quantity of light-emitting sources and light detectors included in the light sensor. For example, the light sensor may include at least one light-emitting source, such as LED Or multiple LEDs, preferably, infrared light, red light, green light, blue light, or white light composed of multiple wavelength light sources, and at least one light detector to obtain pulse rate/heart rate and other blood physiological information For example, respiratory physiological information, where green light and other visible light, such as blue light or white light, are currently the main light sources for heart rate measurement when measuring pulse rate/heart rate, and the main focus is on the interpretation of the AC component; Regarding the effect of breathing on blood, when a person breathes, the pressure in the chest cavity (the so-called intrathoracic pressure) will change with each breath. When inhaling, the chest cavity will expand and cause the chest The internal pressure decreases, so air is drawn into the lungs. During exhalation, the intrathoracic pressure increases and forces air out of the lungs. These changes in intrathoracic pressure will also cause the amount of blood returning to the heart through the veins and the heart into the arteries The change of blood volume, and this part of the change can be known by analyzing the DC component of the PPG signal. In this article, the breathing information obtained by analyzing the PPG waveform is called low-frequency breathing behavior; in addition, since the heart rate is affected by Controlled by the autonomic nervous system, breathing will affect the autonomic nervous system and cause changes in the heartbeat, that is, the so-called sinus arrhythmia (Respiratory Sinus Arrhythmia, RSA). Generally speaking, the heartbeat speeds up during inhalation. During exhalation, the heartbeat slows down, so the breathing changes can also be learned by observing the heart rate. In this article, this is called RSA breathing behavior; therefore, the respiratory physiological information obtained by the light sensor is collectively called breathing behavior.

Furthermore, the obtained heart rate can be further analyzed to obtain other relevant physiological information, such as calculating the heart rate variability (HRV) to understand the activity of the autonomic nervous system, and analyzing whether there are suspected arrhythmia symptoms, etc. .

Alternatively, the light sensor may also include at least two light-emitting sources, such as a plurality of LEDs, preferably, green light, infrared light, and/or red light, and at least one light detector to obtain the blood oxygen concentration (SPO2 ), pulse rate/heart rate, and other blood physiological information. When measuring blood oxygen concentration, two different wavelengths of light are required to enter the tissues, using oxygenated heme (HbO2) and non-oxygenated heme ( Hb) The two wavelengths of light have different absorption degrees, and after receiving the transmitted and reflected light, the result of the comparison between the two can determine the blood oxygen concentration. Therefore, the measurement of blood oxygen concentration is usually for the setting of the optical sensor There are more restrictions on the position. It is better to use the position where the light can actually penetrate the artery, such as the fingers, the inner surface of the palm, the toe, the sole, etc., especially when measuring the blood oxygen concentration of the baby, the toe/foot is often used. The wavelength can be, for example, red light and infrared light, or two wavelengths of green light, such as green light with wavelengths of 560 nm and 577 nm, respectively. Therefore, a suitable light source can be selected according to requirements without limitation.

The wavelength range of the above-mentioned various light sources is that the wavelength of red light is approximately between 620nm and 750nm, the wavelength of infrared light is approximately greater than 750nm, and the wavelength of green light is approximately between 495nm and 580nm. When used for measurement, it is usually used For example, the wavelength of red light is 660nm, the wavelength of infrared light is 895nm, 880nm, 905nm or 940nm, and the wavelength of green light is 510～560nm or 577nm. However, it should be noted that in actual use, depending on the purpose of use, Light sources of other wavelengths can be used. For example, when only the heart rate is to be obtained, as mentioned above, blue light or white light composed of multiple wavelength light sources are also suitable choices. Therefore, for a more accurate description, in the following In the description, “wavelength combination” is used instead of “wavelength” to cover the possibility of using multi-wavelength light sources.

In addition, in particular, light sources with three wavelength combinations can be simultaneously provided. For example, in one embodiment, the first light-emitting source is implemented as an infrared light source to generate light of the first wavelength combination, and the second light-emitting source is implemented as a red light source to generate light of the first wavelength combination. Two-wavelength combined light, and the third light source is implemented as a green light source, a blue light source, or a white light source to generate a third wavelength combined light, where the infrared light source and the red light source are used to obtain the blood oxygen concentration, and the green light source and the blue light source , Or a white light source is used to obtain the heart rate; or, in another embodiment, the light of the first wavelength combination is implemented as infrared light or red light, and the light of the second wavelength combination and the third wavelength combination is implemented as green light or blue light , And/or white light, etc., can use two of the wavelength combinations to obtain the blood oxygen concentration, and the other wavelength combination to obtain the heart rate; or, in another embodiment, the first wavelength combination, the second wavelength combination, and the third wavelength The combined light is all implemented as green light. The blood oxygen concentration can be obtained by the green light of two wavelength combinations, and the green light of the other wavelength combination can be used to obtain the heart rate. As shown above, different parts of the body can obtain blood physiology. There are different types of information. Therefore, having a light source that can generate multiple wavelength combinations at the same time will help achieve the purpose of obtaining various required blood physiological information by moving the same device to different body parts, for example, when it is necessary to obtain blood oxygen For the concentration, move the device to a position where light can penetrate the artery, and when you need to obtain heart rate or other blood physiological information, you only need to have blood vessels or capillaries. Therefore, there is no limit.

Here, it should be noted that when there are three light-emitting sources, the number and location of the photodetectors can be changed according to requirements. For example, it can be implemented as two photodetectors, one photodetector and a single infrared light source and a single red light source are used to obtain blood oxygen concentration, and the other photodetector is implemented as two green light sources to obtain a heart rate ; Alternatively, a single photodetector and an infrared light source, a red light source, and a green light source can be used to obtain blood oxygen concentration and heart rate; or, a single photodetector can be used in addition to a single red light source and a single infrared light source to obtain blood In addition to the oxygen concentration, the heart rate is also obtained with three green light sources, so there is no limit.

In addition, in the selection of the photodetector, when detecting the blood oxygen concentration, because the environment contains other light sources, it is preferable that the photodetector receiving infrared light can be selected with a smaller size to avoid environmental light. On the other hand, the photodetector used to receive green light, blue light, white light, etc., can choose a larger size to obtain effective reflected light, and can further adopt a process that can block other light sources, for example, use The filter material isolates the low-frequency infrared light in the environment to obtain a signal with a better S/N ratio.

Furthermore, when obtaining the heart rate, in order to eliminate noise, such as environmental noise, noise generated by body movements during wearing, etc., multiple light sources can also be set (and the wavelength is not limited, all can be green, or Use light sources of other wavelengths), and perform digital signal processing on the PPG signals obtained by different light sources, such as adaptive filters or subtraction calculations, to achieve the purpose of eliminating noise, so there is no limit.

When setting up, the light sensor will be placed on the lower surface of the circuit board to be close to the bottom surface of the lower shell used to contact the body surface, and it is necessary to consider that the light generated by the light source can actually enter the blood vessel and the light transmitted/reflected It can be reliably received by the photodetector. Therefore, in this application, in order to minimize the volume and simplify the manufacturing process at the same time, in particular, under the premise that the miniature housing is at least a combination of an upper housing and a lower housing, The implementation is to save the space for arranging light-transmitting lenses (lens) in the general prior art by selecting the material of the lower housing as a light-transmitting material. For example, it can be achieved by selecting a transparent material that can transmit visible light, or can transmit other light sources The light emitted, such as infrared rays, is made of the material of the lower shell, thus achieving the effect of reducing the volume. In terms of manufacturing, it also saves the additional step of arranging light-transmitting lenses. The upper and lower shells are separated from each other due to the shell structure Therefore, the two materials can be selected to be the same or different according to requirements without limitation, and through appropriate design, more changes in appearance can therefore be presented. Of course, when the volume size is suitable, the common way of setting the light sensor can also be used, for example, the light-transmitting lens is set at the position of the lower housing corresponding to the light sensor, or the light-transmitting material is filled around the light sensor. limit.

Here, it should be noted that in all the following embodiments, as long as the photosensor is used to obtain physiological information, the above-mentioned content about using light-transmitting materials to make the housing, and/or installing light-transmitting lenses, Fill in the content of the light-transmitting material, so it is based on the principle of brief description, and I will not repeat it in the following description.

Another option for physiological sensing components is electrophysiological input and output components. For example, electrodes are one of the electrophysiological input and output components, such as electrophysiological signal acquisition electrodes, impedance detection electrodes, and electrical stimulation electrodes. .

Generally speaking, there are two types of electrodes, Wet Electrode and Dry Electrode. Among them, the wet electrode refers to the electrode that needs to be in contact with the human skin through a conductive medium. For example, conductive Paste, conductive glue, conductive liquid, etc. are used as conductive media. The most common ones are cup-shaped electrodes that require conductive paste and electrode patches that have been preformed with conductive glue; on the other hand, dry electrodes do not require conductive media. It can be implemented to obtain electrical signals through direct contact with the skin, or can also be implemented in a non-contact form, such as capacitive electrodes, inductive electrodes, or electromagnetic electrodes, etc., and there are many materials available, for example, In other words, it is generally known that conductive materials that can sense the self-generation of the human body can be used as dry electrodes, such as metals, conductive fibers, conductive rubber, and conductive silicone. The electrodes usually arranged on the surface of the housing are mostly in the form of dry electrodes to simplify the operating procedures.

Electrophysiological signal extraction electrodes are mainly used to obtain electrophysiological signals of the human body, such as brain electrical signals, eye electrical signals, electrocardiographic signals, electromyographic signals, skin electrical signals, etc., according to the different electrophysiological signals obtained , Will be set in different body surface areas, for example, head area, neck area (including front and back area), trunk area (including front and back area), limbs, etc.; generally by setting at least two electrodes at the signal acquisition position Obtain the potential change at this position, and because the casing of the present application has a small volume, it is more suitable that no more than one electrode is arranged on a single surface. Therefore, in practice, it is preferable that one electrode is arranged on the bottom surface and contacts the skin at the arranged position. The other electrode changes according to the type of electrophysiological signal to be obtained. For example, the ECG signal can be obtained by arranging another electrode on the surface other than the bottom surface, such as the top surface and the side surface, and making contact with a limb. To achieve this, for example, to make contact with the hand, to obtain other electrophysiological signals, it is preferable to extend another electrode from the housing to capture electrophysiological signals together with the electrode on the housing. The signal can also be obtained in this way; among them, the electrical skin signal is more special because there are two common ways to obtain it. One is to know the impedance of the position by applying a tiny voltage source or current source between the two electrodes The other is to detect the skin potential difference signal between the two electrodes.

It should be noted that in general, when capturing electrophysiological signals, the electrodes that can be used include electrophysiological signal capture electrodes and Driven Right-Leg (DRL) electrodes. Among them, the signal capture electrodes are used to obtain electrophysiological signals. , DRL electrodes are used to eliminate common mode noises, such as 50Hz/60Hz power noise, and/or provide the body potential level (Body Potential Level) to match the circuit reference potential. When used, follow the actual use Under the condition, the two-pole mode can be adopted, using two electrophysiological signal acquisition electrodes to obtain the electrophysiological signal, or the DRL electrode can be added to use the three-pole mode, and the configuration can be flexibly changed without limitation.

Impedance detection electrodes are set on the torso, such as the chest and abdomen, to obtain the impedance signal of the human body. Since this impedance change comes from the muscular tissue impedance change caused by the fluctuation of the chest and/or abdomen when the human body breathes, it can also be By analyzing this impedance change, we can understand the state of sleep breathing. For example, we can understand the presence or absence of breathing action, the size of the breathing amplitude, and the breathing frequency and other breathing-related information.

Electrical stimulation electrodes can be used to provide electrical stimulation to the human body. Common electrical stimulations include, for example, tCS (transcranial Current Stimulation, transcranial electrical stimulation), TENS (Transcutaneous electrical nerve stimulation, transcutaneous electrical nerve stimulation), MET (Microcurrent Electrical Therapy) , Microcurrent electrotherapy), and other known electrical stimulation, among which common forms of tCS include tDCS (transcranial Direct Current Stimulation, transcranial direct current stimulation), tACS (transcranial Alternating Current Stimulation, transcranial alternating current stimulation), and tRNS (transcranial Random Noise Stimulation, Transcranial Random Noise Stimulation), in which transcranial electrical stimulation is applied to the local physiological tissue above the cerebral cortex, which in turn affects the activity of the corresponding cerebral cortex. The applied current is very weak, for example , The applied current range is usually less than 2 milliamperes. Therefore, during the electrical stimulation, the subject usually does not have obvious feeling; in addition, TENS and MET are often used to relieve local symptoms of the body, such as muscles Sore, quite versatile.

Another type of electrophysiological input and output element is a respiratory airflow sensor used to obtain changes in respiratory airflow, such as thermistors and thermocouples, which are placed in the nose and mouth area, for example, between the nose and mouth to obtain changes in respiratory airflow. Among them, it is feasible to choose two detection points near the nostrils, or three detection points near the nostrils and the mouth.

Another option for physiological sensing components is an accelerometer. For example, a three-axis accelerometer is usually installed on a circuit board in the device housing. It can be used to detect body posture, physical activity and other information. If used during sleep , It can provide sleep posture, sleep physical activity and other information. Among them, the three-axis accelerometer will return the acceleration values measured in all three dimensions of x, y, and z, and based on these values, you can get Based on the above-mentioned various information, and by analyzing physical activity during sleep, further information about sleep stages/states can be obtained; alternatively, other types of accelerometers, such as gyroscopes, magnetometers, etc., can also be used. Furthermore, when the device containing the accelerometer is placed on the body surface where the body surface vibrations and undulations can be felt, it can also detect other physiological information. For example, it can detect body cavity vibration caused by snoring. For example, it can be obtained on the torso, neck, head, ears and other positions. Among them, the torso and head are the best positions to obtain, especially the nasal cavity, throat, chest and other positions can transmit the vibration caused by snoring well. , Is a very advantageous choice; it can also be set on the torso to obtain the acceleration and deceleration caused by the chest and/or abdomen undulations during breathing; it can also detect the vascular pulse generated by the blood pulse to obtain the heart rate and obtain the position Not limited, for example, the head, chest, upper limbs, etc. are all obtainable positions; in addition, the physical activity information obtained by the accelerometer can also be used to determine whether the signal is caused by body movement or movement when analyzing physiological signals Poor quality.

In addition to the detection of snoring using the accelerometer mentioned above, the piezoelectric vibration sensor can also be used to detect the body cavity vibration caused by snoring. The setting position is the same as that of the accelerometer, or the microphone can be used for sound detection. Among them, the microphone will report the frequency and amplitude of the measured sound, and the appropriate filter design of the acoustic transducer can detect the sound of sleep, such as snoring or breathing.

In addition, breathing motion can also be detected by other physiological sensing elements. For example, one option is a piezoelectric motion sensor, which is placed on the torso, which is obtained by applying force to the piezoelectric motion sensor through breathing motion The signal is usually implemented as a band around the torso, or it can also be implemented as a fixed patch; another option is the RIP (Respiratory Inductance Plethysmography) sensor, which is placed on the torso to obtain breathing movements The resulting expansion and contraction of the chest and/or abdomen are usually implemented as a belt around the torso.

Another option for physiological sensing elements is a temperature sensor to detect device temperature, ambient temperature, or body temperature. In order to obtain body temperature information, it is preferable to arrange the temperature sensor on the surface of the housing contacting the body surface , Either a temperature-conducting material is provided on the surface of the housing to transmit the temperature signal to the temperature sensor, or a radiation-sensitive temperature sensor can also be used without touching the skin.

So far, all the components, modules, parts, etc. required for physiological testing have been completed, and the overall volume is only slightly larger than the volume of the battery used, for example, the length, width and height fall from 10×10×10 mm to 20×20 Within the range of ×20mm, for example, 18×18×12mm, a miniaturized physiological device is indeed achieved, and it can adapt to the target of multiple position curves of the human body, such as fingers, ears and other narrow setting positions Both can be set.

Next, various possible implementation forms of the micro-physiological device of this application are described.

In order to enable the miniature housing to be placed in the common locations of general physiological devices, such as wrists, soles of feet, torso, etc., it can also be placed in other tiny body surface setting spaces, such as fingertips, ears, and head behind ears. Forehead, forehead, etc., the method adopted in this application is to match various suitable wearing structures to achieve the change of the setting position.

One of the embodiments is to adhere the micro-shell to the surface of the human body. The advantage of the adhesion method is that it can have a good fixing effect in various undulating body surface areas, so that the arrangement and use of various physiological sensing elements are not restricted, for example, physiological sensing elements It can be set to the most suitable sampling position, and the contact between the shell and the skin can be more stable.

The embodiment is to provide an adhesion structure so that the shell is closely attached to the user's integrated watch area, as shown in FIGS. 3A-3G, wherein the adhesion structure includes an adhesion structure 30 and an adhesion substance 31. The adhesion structure 30 will form an attachment body with the housing 100, and the adhesive substance 31 is used to adhere the attachment body to the skin surface, wherein the attachment body has a protruding edge 302, which includes an upper surface and a lower surface, And it is implemented as being arranged on the body surface area with the lower surface facing the skin.

One embodiment is that the attachment structure is implemented to be combined with at least a part of the housing to form the attachment body, wherein the attachment structure has an accommodating space 301 for receiving the housing 100 and placing it in the housing. The protruding edge 302 extends from the edge of the space, so that the bottom edge of the micro-shell has a fixed structure, especially the lower surface of the protruding edge is used to contact the body surface, and the increased surface area provides space for the adhesive material. , It also helps to make the bottom of the lower shell more stable. It should be noted here that the protruding edge can be implemented as a circle around the accommodating space, or can be implemented as only falling on opposite sides, or other positions, which can also be changed according to actual needs without limitation.

As shown in FIGS. 3A-3B and 3E, the adhesive material 31 can be directly implemented as at least a part of the lower surface of the protruding edge to achieve the purpose of adhesion, and there is no limit to the area and scope of the setting, as long as the adhesion can be achieved. The effect of the attachment body is sufficient; alternatively, as shown in FIGS. 3C-3D and 3F-3G, an adhesive attachment 32 may be used to carry the attachment substance 31, that is, the attachment attachment may be placed on the body surface At least one surface of the area is adhered and fixed by covering at least a part of the attachment body by the adhesive attachment. The area covered by the adhesive attachment may be at least a part of the upper surface of the protruding edge 302 as shown in the figure. , It can also be the entire attachment body (not shown) without limitation, as long as the adhesion and fixation effect can be achieved.

The accommodating space and the miniature housing have different possibilities for combination. For example, FIGS. 3A-3C show the attachment structure in the form of covering, and FIG. 3A shows a situation where the accommodating space entirely covers the housing, and Figures 3B-3C show that the casing further has a joint level difference, and the top of the accommodating space is implemented with a hole corresponding to the joint level difference, so as to use the engagement between the joint level difference and the hole to achieve a fixing effect. It is particularly suitable for embodiments that also have physiological sensing elements on the upper surface, for example, an embodiment in which ECG electrodes are arranged on the top surface for upper limbs to contact; in addition, Figures 3F-3G show the attachment structure in the form of a base, and this attachment base structure This allows the shell to be inserted from above, providing another operation option. For example, the attachment base structure can be set in the body surface area before the shell is inserted. In this case, the accommodating space and the shell Magnetic attraction and/or mechanical engagement can be used to achieve the combination between each other, or the accommodating space can also be implemented as a flexible material such as silica gel to be combined by a sleeve. Therefore, there are various possibilities and no limits.

There are also various implementation possibilities for the material of the attachment structure. For example, plastic can be used, which is light in weight, has a certain degree of elasticity and rigidity, and helps to fit the body surface and fix it, and in particular, as shown in the figure The embodiments shown in 3A-3C can be implemented in the form of a blister, which simplifies the manufacturing process and reduces the cost. When implemented as a transparent plastic, visually it is almost equivalent to only the housing being placed on the body, which further provides aesthetic advantages; or , It can also be made of other materials, such as silica gel, non-woven fabrics, etc., which have the advantage of being soft, and can also provide the functions of housing the shell, fitting on the body surface, and being easily fixed; moreover, housing space and protruding edge It can also be made of different materials. For example, the housing space uses a harder material to achieve the effect of fixing the shell, and the protruding edge uses a softer material to respond to the fluctuations of the body surface, so there are various Possibly, no limits. In addition, the attachment structure and/or the adhesive attachment can be further implemented in a disposable form to provide users with convenient use options.

Another embodiment is that the attachment structure and the housing are formed integrally, as shown in FIGS. 3D-3E, that is, the housing itself has a protruding edge to further simplify the structure, which helps simplify the manufacturing process and To reduce the cost, it can also be fixed by using only the adhesive material or the method of using the adhesive attachment to carry the adhesive material, without limitation.

Here, in particular, the combination of the attached base structure and the housing as shown in FIG. 3G provides an embodiment in which the photosensor can still obtain blood physiological information through the bottom surface of the lower housing when the base structure is adopted. , The bottom surface of the housing is implemented with a protruding structure 181 for setting the light sensor, and correspondingly, the bottom of the accommodating space of the base attachment structure has an opening for the protruding structure to pass through, such a Now, when the miniature housing is combined with the attachment base structure, the top end of the protruding structure can pass through the opening, and the photosensor provided therein can also obtain physiological information. For example, the protruding structure can be It is configured to form the same plane, or slightly convex, or slightly concave with the lower surface of the protruding edge, without limitation.

The internal structure of the protruding structure 181 is shown in FIG. 4. In order to install the photosensor 20 in the protruding structure, the photosensor is first combined with a circuit board 161 to form a photosensor module. The light sensor module is then mounted on the circuit board 16 to form an electrical connection with the control unit. In this way, through the height of the block circuit board, the light sensor can enter the protruding structure downward to make the transmitter The light generated by the light source smoothly enters the human body, and the light detector smoothly receives the reflected light. Here, as mentioned above, it can be implemented that the entire lower housing is made of a light-transmissive material, or it can be implemented that only the protruding structure is made of a light-transmitting material, or under the protruding structure There are various implementation possibilities without limitation by providing lenses or light-transmitting materials on the edge.

Alternatively, in addition to the form with a protruding edge, it can also be implemented as a form without a protruding edge. In this case, the above-mentioned adhesive attachment can be directly used to fix by covering, for example, the adhesive attachment can be directly used to cover and adhere without protrusion. The shell or the base structure of the edge can also be implemented without a protruding edge and covered and fixed with an adhesive attachment, so there are various possibilities without limitation.

On the other hand, when electrophysiological input and output components are mainly used, other implementation possibilities are possible, as shown in FIGS. 5A-5B, which can be achieved by combining an electrically extending base structure 50 with the housing 100. The electrically extending base structure includes a main casing 501 and an extension body 502 extending from the main casing 501, wherein the main casing is at least composed of an upper casing and a lower casing, for example, By means of ultrasonic combination, and the upper casing is constructed to have an accommodating space for arranging the miniature casing, and an inner space is formed between the upper casing and the lower casing for disposing A circuit substrate (not shown); here, the circuit substrate has various implementation options, for example, a rigid circuit board, a flexible circuit board, etc. can be used to carry electrical components, and other materials can also be used, for example, can carry printing ink The base, there is no limit. The extension body has an upper surface and a lower surface, and the lower surface faces the body surface. Since the extension body is used to set the main part of the body surface, it is preferably made of an elastic material, for example, directly using soft Flexible circuit boards, or silicone-carrying electrical connecting wires, etc., to better fit the curve of the body surface area where the installation is located. In the case of using a flexible circuit board, it can be implemented as a direct circuit substrate from the space inside the case. Extend outwards to serve as the extension body, simplifying the manufacturing process and reducing the cost.

In addition, the electrically extending base structure also includes at least two electrical contact components 503 and at least two electrophysiological input and output elements 504, wherein the at least two electrical contact components are disposed on the circuit substrate in the space of the housing and exposed to the accommodating device. In the space, when receiving the miniature housing, electrical contact is made with at least two electrical contact parts 101 on the bottom surface of the miniature housing (please refer to FIG. 1), and in this case, the miniature housing is electrically contacted Components are electrical contact components that are used to perform electrical extension or used as electrodes in addition to charging, communication and other purposes. The difference between the two is only whether the housing can be directly obtained by using these electrical contact components when the housing is used alone The electrophysiological signal can be changed according to actual use requirements without limitation. Furthermore, the at least two electrophysiological input and output elements 504 are disposed on the extension body 502, and are electrically connected to the accommodating space. The at least two electrical contact components 503, in this way, achieve electrical connection between the at least two electrophysiological input and output elements and the control unit in the miniature housing, so that the electrophysiological input and output elements can perform related electrophysiological operations.

The advantage of this is that it can adapt to different sampling requirements by changing the structure of the electrical extension base, for example, changing the type of electrophysiological input and output components, and/or changing the distance between two electrophysiological input and output components. The miniature housing mainframe can be changed quickly and simply by changing a different electrical extension base structure, which is quite cost-effective. In addition, under such a structural design, the electrical extension base structure is very simple and the cost is very low. It can also be implemented in a disposable form based on hygiene considerations, which is quite advantageous.

As mentioned earlier, the electrophysiological input and output components can be used to obtain electrophysiological signals, such as ECG signals, brain electrical signals, eye electrical signals, electromyographic signals, skin electrical signals, and can also be used to detect impedance signals, for example, Breathing action, alternatively, can also be used for electrical stimulation, and the structure of the electrical extension base can have various changes according to different purposes of use.

For example, in a preferred embodiment, as shown in FIG. 6, the two electrical input and output elements 504 on the extension 502 are implemented to be mechanically and electrically connected to the coupling members 601 and 602, respectively. The coupling member is then used for mechanical and electrical connection with a button electrode 603. In this way, the button electrode can be used to capture electrophysiological signals. For example, the ECG signal can be obtained according to the different setting positions. Electrical signals, ocular signals, myoelectric signals, and/or electrical skin signals can also be used to detect impedance signals and perform electrical stimulation. As shown in the figure, the combination parts 601 and 602 use upper and lower joints To achieve mechanical and electrical connection with the electrophysiological input and output component 504, this method is not only simple in manufacturing process and good in connection and fixation, but also suitable for button electrodes of different combinations, for example, when there is a male button or female button For different types of button electrodes, it can be matched only by changing the form of the connecting piece, which is quite convenient.

Here, the combined button electrode can be a wet electrode or a dry electrode. When implemented as a wet button electrode, the adhesion between the wet electrode and the skin can be used to produce the effect of fixing the electrically extended base structure to the body surface, and the use of wet electrodes also helps to perform electrical stimulation; When it is implemented as a dry button electrode, when setting, the dry button electrode can be fixed by the adhesive attachment first, and then the connecting piece can be fastened to achieve the purpose of fixing the electric extension base structure. The advantage of using a combined button electrode is that the contact between the electrode and the skin is independent of the extension body, which is relatively stable, and the quality of obtaining electrophysiological information is improved, and the electrical stimulation provided can also be more stable. In addition, because the button electrode is implemented in a removable form, it can be replaced separately. For example, the wet electrode can be replaced after the viscosity is lost. There is no need to replace the entire electrical extension base structure, which can save costs. In addition, as long as the settings are changed for different needs The position and the corresponding replacement of the appropriate button electrode can be suitable for various electrophysiological signal acquisition, impedance signal detection, and/or electrical stimulation provision, which has great advantages.

In addition, in another embodiment, the electrical input and output elements on the extension body can also be used directly as electrodes, that is, to capture electrophysiological signals in direct contact with the skin. Therefore, preferably, the The material of the extension body is implemented as a material that is flexible and can fit the body surface to improve the comfort of use. For example, one possibility is to use a flexible circuit board as the extension, for example, the circuit substrate is directly extended outwards. In this case, the electric circuit formed on the flexible circuit board can be directly used. Contact pads are used as electrodes, and this technology that directly uses electrical contact pads as electrodes can be found in various series of products such as Muse S and Muse 2 produced by muse ^TM , a manufacturer of wearable brain electrophysiological detection devices. Therefore, it will not be repeated; Figure 7 shows an embodiment using this architecture, which is used to obtain EEG signals/eye signals from the forehead, wherein the electrical extension base structure described above is further implemented with a carrying structure 70 is combined to be set on the forehead of a user, and as shown in the figure, after the two are combined, the electrical contact pad 5041 on the extension 502 will be exposed. In this way, when set on the forehead, The exposed electrical contact pad can directly contact the forehead to capture EEG signals. Then, only need to fix the supporting structure 70. For example, it can be combined with a belt around the back of the head to achieve a loop The fixation is quite convenient; alternatively, electrodes can also be arranged on the electrical contact pads, such as the aforementioned dry electrode or wet electrode, to further make the electrode contact more stable, so there is no limitation.

In addition, in particular, it can also be implemented in the form of a necklace placed in front of the torso to obtain ECG signals. In this case, as shown in FIG. 8, a neck-wearing structure 80 is used to place the housing on the torso. In the front, the neck-wearing structure has a neck fixing part 801 for fixing with the neck, and a trunk contact body 802 for combining with the electrically extending base structure, and then acting as a hand pressing to make the electrodes contact A medium for the trunk, wherein the trunk contact body has two electrophysiological signal acquisition electrodes 803, for example, a dry electrode, and correspondingly has two electrical connection abutting members 804 to achieve the The electrical connection between the electrophysiological signal acquisition electrode 803 on the trunk contact body and the electrophysiological input and output element 504 on the extension body, after which the two electrophysiological signal acquisition electrodes on the trunk contact body are oriented toward The direction of the torso can provide the user with the purpose of pressing the electrode to contact the skin when necessary to obtain the ECG signal, which is also a very advantageous embodiment.

Furthermore, as shown in FIG. 9, based on the compact size of the miniature housing of the present application, it is also suitable for being placed in the mouth and nose area. Therefore, the electrophysiological input and output element can also be implemented as a respiratory airflow sensor 901, such as a thermistor, Thermocouples, etc., in this case, the electrically extending base structure will be set in the mouth and nose area, for example, between the mouth and nose, and/or the cheek, and the position of the electrophysiological input and output element is required as described above. It is arranged at a position where changes in breathing airflow can be sensed, for example, near the nostrils, near the mouth, so it is preferably arranged on the upper surface of the extension body. Here, the fixing of the electrical extension base structure has different possibilities. For example, an adhesive substance can be directly placed on the lower surface of the extension body for adhesion, or the two ends of the extension body can be fixed by using adhesive attachments as shown in the figure, which can be changed according to the actual shape and installation position without limitation. . In addition, the position of the accommodating space on the extension body used for arranging the housing 100 can also be different according to requirements to meet different usage and installation requirements. For example, it can be arranged in the center of the extension body so that the housing The body is located between the nose and mouth, and can also be offset to one side of the extension body so that the shell is located on the cheek. So there are various possibilities and no limits.

So far, in the above-mentioned cases, the length and shape of the extension body are determined according to the position where the electrical input and output elements are to be installed. For example, it can be elongated shapes of various sizes, or irregular shapes, etc., while operating At this time, it is preferable that the electrically extending base structure can be fixed/set up first, and then the micro-shell can be combined, which is quite convenient.

Further, in the case of using the electrically extended base structure, the light sensor can also be used to obtain blood physiological information. In order to ensure that the light sensor can obtain good physiological signals from the skin, preferably, as shown in FIG. 10, the micro The lower surface of the housing is implemented with a protruding structure 181 to provide a light sensor, and correspondingly, the bottom of the accommodating space of the electrically extending base structure has an opening for the protruding structure to pass through. When the miniature housing is combined with the electrically extending base structure, the top end of the protruding structure can pass through the opening, and the photosensor disposed therein can obtain physiological information. For example, the protruding structure can be constructed In order to form the same plane, or slightly convex, or slightly concave with the extension body, this is similar to the situation shown in FIG. 3G, and the adopted protrusion structure has a similar structure design, so it will not be repeated here.

In this way, the light sensor can capture physiological information together with the electrophysiological input and output components. For example, when it is installed on the forehead, it can obtain the blood oxygen concentration and EEG signal at the same time. When it is installed on the trunk, it can obtain the heart rate and heart rate. When the electrical signal is installed in the nose and mouth area, the flow change of the respirator and the blood oxygen concentration can be obtained at the same time, which helps to have a deeper understanding of the physiological state of the user; and, through such a structural design, the electrical extension In the case that the base structure is implemented as replaceable or disposable, the optical sensor with higher cost and more complicated electrical connection can be reused with the housing, which is extremely cost-effective.

So far, the combination of the above-mentioned miniature housing and the attached base structure and/or the electrically extending base structure can also have additional advantages. As mentioned above, in addition to the electrical contact components for electrical extension, the bottom surface of the housing is also provided with electrical contact components for charging and/or communication. Therefore, electrical safety issues that may occur when installed on the body surface area should be considered. In this case, through the use of the base structure, the contact between the charging/communication electrical contact parts and the skin can be effectively isolated. For example, in the attached base structure as shown in Figure 3G, since only the bottom of the accommodating space is opened Corresponding to the opening of the protruding structure, so as long as the charging/communication electrical contact component is placed in a position other than the protruding structure, it can naturally achieve an isolation effect when combined with the attached base structure; in addition, as shown in Figure 5A In the electrical extension base structure, it does not have a protruding structure, and the entire bottom surface of the housing is insulated. In the case of a protruding structure as shown in Figure 10, similarly, the charging/communication electrical contact component can be arranged on the protruding structure. Exclude other locations outside the structure to achieve an isolation effect.

Alternatively, when the base structure is not adopted, other methods can also be used to achieve the effect of isolating electrical contacts. For example, as shown in FIG. 11, an insulating layer 110, such as a thin silicone sleeve, can be wrapped around the casing to cover the electrical contact parts on the bottom surface, and the same effect can be achieved. Therefore, there are various possibilities and no limits.

Further, it can also be implemented to additionally have a charging base structure, a communication base structure, or a charging communication base structure, which is combined with the housing to perform charging and/or communication procedures. Here, similar to the aforementioned base structure, preferably, as shown in FIG. 12, the charging/communication base structure 120 will have an accommodating space for receiving the housing, and the accommodating space will have a charging/ The communication electrical contact component 1201 is used to achieve electrical contact with the charging/communication electrical contact component on the housing; in addition, the charging/communication base structure will also include a communication interface 1202, such as a USB interface, to communicate with an external device Connect to achieve charging/communication procedures. Here, in particular, if the housing with a protruding structure is received, a corresponding opening 1203 needs to be opened at the bottom of the accommodating space, and if the housing without a protruding structure is received, then The bottom of the accommodating space can choose to open or not open an opening, and there is no restriction.

Further, when the housing is implemented to be fixed with the accommodating space of the attachment structure and/or various base structures by magnetic force, it is preferable that at least one first magnetic substance 102 is disposed on the housing ( Please refer to FIG. 1), and at least one second magnetic substance is disposed in the accommodating space (not shown) to achieve the purpose of mutual combination through the magnetic attraction between the paired magnetic substances, and, more advantageously, Using the principle of mutual attraction and repulsion between magnetic substances of the same sex, coupled with the designed arrangement positions of magnetic substances on the casing and in the accommodating space, will further provide orientation and limit effects. For example, It is preferable to set the magnetic substance at a position off-center, for example, off-center or off-center, to ensure the correctness of the bonding direction, and avoid when the housing is implemented as a circle, square, rectangle or other symmetrical shapes When the contact position is wrong, more than two pairs of magnetic materials can also be used. In addition to using the magnetic difference to make the positioning effect better, the increase in force points also allows the combination between the two The force can be more even, and the phenomenon of incomplete contact can be avoided. In particular, the combination of the above-mentioned various base structures and the shell mostly involves the realization of electrical contact, such as the electric extension base structure, the charging/communication base structure, etc. The design will help to achieve correct and stable electrical contact, thereby ensuring the smooth progress of signal acquisition and charging/communication procedures, which is a very important part.

Here, due to the small volume of the housing, in order to achieve the effect of orientation and limit, it is preferable to use a small-sized magnetic material to avoid the expected effect that the magnetic field is larger than the housing; The first magnetic substance on the miniature housing can be arranged inside the housing, or embedded in the housing wall, for example, integrally formed with the housing, or attached to the outer surface of the housing, for example, After the shell is formed, the magnetic substance is attached by pasting, and there are various implementation possibilities without limitation.

Furthermore, when the combination of the miniature housing and the base structure involves electrical contact, for example, the charging/communication base structure and the electrically extending base structure, there are also many possibilities for how to achieve and maintain the electrical contact between the housing and the base structure. . In a preferred embodiment, a thimble connector (pago pin) is used, in which the electrical contact parts on the housing and the electrical contact parts on the base structure are paired with each other, for example, used together In order to perform electrophysiological operators and those used together for charging and/or communication procedures, at least one of each pair of electrical contact parts is implemented as a thimble connector, so that the thimble connector can be stretched and contracted by force The electrical contact between the two can be ensured. As shown in FIG. 13, the electrical contact member 101 located on the lower surface of the housing and the electrical contact member implemented as the ejector pin connector 130 in the base structure are paired to achieve electrical contact.

In particular, in actual implementation, since there will be multiple pairs of electrical contact parts for various purposes, for example, there are both electrical extension electrical contact parts and charging/communication electrical contact parts. Therefore, how to properly distribute , Very important. First of all, in the case of a certain volume of the thimble connection device, if all the thimble connectors are arranged in the shell, the volume of the shell will be too large. On the other hand, if the thimble connectors are all arranged in the base structure, although There is a large space to accommodate, but if the base structure is implemented as a throwable, for example, a throwable electric extension base structure, it will cause the cost to rise. Furthermore, as we all know, the thimble connector has retractable elasticity. When two thimble connectors are used in parallel, the elasticity of the expansion and contraction is added to each other, especially when more than three electrode contact points (constitute a plane), a greater combination force will be required to overcome the sum of the expansion and expansion elasticity to ensure the shell and the base The combination between the structures and each pair of electrical contacts are achieved. For example, when the magnetic attraction is used for the combination, the magnetic force of the attraction must be greater than the sum of the elastic force to ensure the combination between the two and the multiple electrical contacts. Stable reached. Therefore, it is preferable to separate the thimble connector in the housing and the base structure, so that the volume, cost, elasticity, etc. can be more evenly distributed.

Accordingly, in the actual implementation of this application, among the plural pairs of electrical contact parts, the use of the thimble connector is divided into two parts, that is, the first part is a pair of electrical contact parts and the second part is a pair of electrical contact parts, for example Since the electrophysiological signal acquisition procedure and the charging/communication procedure will not be performed at the same time, the first part of the paired electrical contact parts can be implemented for charging/communication, and the thimble connector is arranged on the power/communication base structure, And the second part of the paired electrical contact parts can be implemented for electrical extension, and the thimble connector is arranged on the housing. For example, when using a USB port for charging/communication, 4 pairs of electrical contact parts are required, In addition, for electrical extension applications, 2-5 pairs of electrical contact parts are required according to the number of electrodes. In this way, in addition to the effective reduction in the volume of the housing and the cost of the base structure, each combination of the housing and different base structures requires The number of overcoming thimble connectors can be reduced, which helps to achieve electrical contact more easily and stably. Especially when using magnetic force to attract and combine, the reduction of required magnetic force also allows the volume of magnetic materials to be maintained in a small size. The miniaturization of the shell volume also helps.

So far, through the various embodiments described above, the micro-housing of the present application can be installed in various positions of the human body, and the physiological sensing elements can also be correctly installed to obtain stable and high-quality physiological information, and based on the small size , The user's setting burden is quite small, which is very advantageous.

Next, we will describe the more special setting positions, ears.

Generally speaking, the ear is a good position for obtaining various physiological signals. For example, when a light sensor is set, it can obtain blood physiological information such as heart rate, blood oxygen concentration changes, etc. When setting a signal extraction electrode, it can be Obtain various electrophysiological signals, such as brain electrical signals, electrocardiographic signals, electromyographic signals, skin electrical signals, etc. When other physiological sensing elements are provided, other physiological information can be obtained, such as changes in body temperature, body Activity information, breathing situation, snoring related information, etc. However, due to various restrictions such as the narrow space in which the ears can be used to install the housing, the location is limited, and the housing is difficult to fix, it has always been difficult in actual implementation.

However, the small size of the miniature housing of the present application just breaks through the above-mentioned limitation. Therefore, whether it is installed on the inner side of the ear, on the ear, or near the ear, it can be realized. The following examples illustrate various possibilities.

In one of the ideas, the simplest and most direct way is to use adhesion and attach it behind the ear, for example, the hairless area behind the auricle, close to the temporal lobe of the cerebral cortex, as shown in Figure 14. As shown in the above, the upper half area behind the auricle corresponds to the cerebral cortex below the skull, and when set at this position, the aforementioned various adhesion structures or base structures can be used, for example, the adhesion structure, the attachment base structure, Electrically extend the base structure for fixation. Relatively, the physiological sensing element can also have various options. For example, a light sensor can be provided to obtain blood physiological signals. Among them, in addition to obtaining the heart rate, when the setting position is below Corresponding to the cerebral cortex, the blood oxygen concentration can be obtained; in addition, when the bottom and top surfaces of the housing are equipped with electrophysiological signal acquisition electrodes, the ECG signal can be obtained, or other electrical signals can be obtained by combining with the electrical extension base structure. Physiological signals, such as brain electrical signals, electromyographic signals, skin electrical signals, etc.; in addition, temperature sensors, accelerometers, microphones and other physiological sensing components can also be set to obtain body temperature information, physical activity information, snoring related information, etc. Other physiological information. Therefore, there is no limit.

In this case, the shell can not only be hidden behind the auricle, but it is not easy to fall off by pasting, and it can be applied to almost any occasion, such as during exercise, daily life, sleep, etc., which is very convenient; further , As long as the adhesion structure adopts the covering form and provides waterproof function, it can also be used during bathing and swimming, which has more advantages.

In another conception, the wearing structure (ear-wearing structure) can be used to set on the ear. Due to the very small size of the casing of the present application, many positions in the prior art that cannot be installed smoothly become feasible, which can be achieved by designing a suitable wearing structure (ear wearing structure).

First of all, when the volume of the housing is small enough, it becomes feasible to install the housing in the ear. According to the structure of the ear, as shown in Figure 15, the suitable position for placing the housing in the ear is the space formed by the concha cavity and the ear canal, and in order to enable the housing to be stably installed therein, as shown in Figures 16A-16D As shown, the present application adopts an inner ear maintenance structure 160.

In this space, first of all, since the ear canal is a channel for receiving sound, it is preferable that the housing is biased toward the concha cavity when the housing is set to avoid blocking the ear canal and causing external sound to be blocked. , Especially, when used during daily life, it may need to be worn for a long time to maintain the ability to receive sounds from the outside without affecting hearing, which is very important to improve the safety of use. In addition, because the light sensor is in this embodiment Physiological information is obtained through the bottom surface of the lower housing. Therefore, compared to the setting position of the ear canal opening, it is more inclined to the setting position of the concha cavity, which can ensure that the light emitted by the light source can effectively enter the blood vessel, that is, The blood vessels in the tissue below the bottom of the ear concha cavity to obtain blood physiological information. Here, as mentioned above, preferably, the lower housing can be implemented as a transparent material to facilitate the penetration of light from the light source into the concha cavity, but without limitation, it can also be configured to It can be achieved by optical lenses, or by setting light-transmitting materials.

Accordingly, the ear-maintaining structure 160 according to the application of the present invention is implemented as having a sleeve component 161 and an abutting component 162, wherein the sleeve component 161 is used for combining with the housing 100, for example, covering At least a part of the casing, and the lower casing of the casing is inserted into the auricle in the direction toward the bottom of the concha cavity, the abutting member 162 protrudes from the sheathing member, facing and abutting against the position of the tragus, so First, since the middle of the tragus and the concha cavity is the opening of the ear canal, the housing can be maintained at the position of the concha cavity by the behavior of the abutting member protruding against the tragus.

Further, in order to allow sound to pass into the ear canal, the purpose is achieved by changing the shape of the top member. As shown in Figures 16A-16D, when the ear-maintaining structure is set in the auricle, at least one channel 163 is formed between the sleeve member and the tragus. For example, Figure 16A shows that the abutting member is directly A channel 163 is formed. In addition, FIGS. 16B-16D show that the at least one channel is formed by the top member, the concha wall of the concha cavity, and the tragus. That is, the in-ear maintenance structure does not cover the entire space Instead, it will provide a path for the sound to pass near the ear canal mouth, so that the sound will not be blocked, so as to improve the safety of use.

In addition, in addition to the top part facing the tragus, other top parts can also be added, for example, the top part that faces up against the concha wall around the concha boat, and faces the concha wall opposite to the position of the tragus. The top part of the sensor to increase the stability of the setting, in addition to reducing the possibility of falling off during wearing, it also makes the light sensor's sampling more stable and better signal quality.

Preferably, the entire inner ear maintenance structure or the supporting member is made of elastic material, such as silicone, rubber, or other elastic materials, which can not only increase the comfort of use, but also provide cushioning and slight adjustment Function.

In addition to light sensors, other physiological sensing components can also be added, such as accelerometers, temperature sensors, microphones, electrodes, piezoelectric vibration sensors, etc., to obtain other physiological information, such as physical activity information, sleep posture, snoring There are no restrictions on related information, electrophysiological signals, etc.

Furthermore, another possibility is to set the shell on the auricle. As mentioned above, the casing of the present application is small in size and light in weight, so it will not be burdened even if it is installed on the auricle, wherein magnetic force can be used to achieve the installation.

As shown in FIGS. 17A-17B, a magnetic attraction structure 170 is used to install the miniature housing on an auricle part of an auricle, which includes a receiving part 171, a connecting part 172, and a magnetic part 173 , Wherein the accommodating component 170 is used to combine with at least a part of the housing 100, and the connecting component 172 is used to connect the accommodating component 171 and the magnetic component 173, and when in use, the connecting component has Deformation characteristics, so that the combined housing and the accommodating component can be located on one side of the auricle part, and the magnetic component can be located on the other side of the auricle part, and the two are separated from each other by the auricle part Opposite, and fixed on the auricle part by the principle of magnetic attraction.

Here, there are various possibilities for the implementation of the accommodating component. For example, it can be implemented in a surrounding manner (Figure 17A), or can also be implemented in a form of covering (Figure 17B), without limitation. In addition, the deformation characteristics of the connecting component can be achieved in different ways. For example, the deformation characteristics can be achieved through the characteristics of the material itself, such as silicone, rubber, etc., or components in the form of ropes and chains can also be selected. To achieve the deformation characteristics, there is no limit. Furthermore, the magnetic component contains a magnetic substance, which is combined with the accommodating component and the housing to achieve the effect of magnetic attraction. As for the magnetic attraction, there are several ways, for example, The magnetic substance can be directly arranged in the casing, for example, between the lower casing and the circuit board, or the magnetic substance can be embedded in the wall of the lower casing or attached to the bottom surface of the lower casing to interact with the magnetic force. The components attract each other. Alternatively, a magnetic substance can be placed on the accommodating component. As shown in FIG. 17B, a magnetic substance 174 is placed at the bottom to attract the magnetic component. Therefore, it can be based on actual needs. Various changes, no restrictions. In addition, it can be seen from the above that the accommodating component, the connecting component, and the magnetic component, in addition to the magnetic substance contained therein, can be implemented as made of the same material according to actual needs, or can be implemented as a combination of different materials. There is no limit.

As we know, the physiological structure of the auricle is divided into the cartilage part and the earlobe (the part without cartilage). Among them, the cartilage part is harder, and the lower earlobe is softer. Because the thickness of the auricle is generally not much different between individuals Therefore, the magnetic force required to achieve mutual attraction through the auricle can be effectively controlled. In addition, the housing of the present application is small in size and light in weight, so it is quite suitable for being fixed to the ear by using magnetic force on both sides of the auricle. As for the fixed position, in addition to the common earlobe, the auricle with cartilage is also almost unlimited. For example, the area between the helix and the antihelix foot, that is, the upper half of the auricle, the auricle Positions such as boats and concha cavities are all positions that can be set using magnetic attraction. Among them, the cartilage part provides better support due to cartilage, and the housing and physiological sensing elements can be set more stably, which helps It is an advantageous choice for obtaining high-quality physiological information.

In addition, without limitation, in implementation, the housing can be arranged on the front side of the auricle or on the back side of the auricle, which can be changed according to the actual situation. Moreover, when the housing is arranged on the ear on the front side of the auricle When in the concha cavity and/or the concha boat, preferably, the accommodating member can further extend out of the top member to abut against the concha cavity and/or the concha wall around the concha boat to achieve further fixation The effect contributes to a more stable shell setting.

The various possibilities of using the magnetic attraction structure to set up are determined by various factors such as the physiological sensing element used, the type of physiological information to be obtained, and the aesthetics during use. For example, When you want to use the optical sensor to obtain blood physiological information, you need to pay attention to the bottom surface of the lower housing facing the sampling position, and the sampling position depends on the type of blood physiological information to be obtained, for example, blood oxygen concentration and/or heart rate; when using electrophysiology When the signal acquisition electrode is used, depending on the type of electrophysiological signal to be obtained, another electrode may need to be extended, for example, extended from the housing to be placed on the same pinna, another pinna, or skull; acceleration; The device also has a different setting position according to the physiological information to be obtained. For example, if you want to obtain snoring-related information, you need to set it at a position where the body cavity vibration caused by snoring can be sensed. No limit; the temperature sensor needs to be set up where the body temperature information can be obtained; the microphone needs to be set up where the sound can be obtained. Therefore, the housing is not limited to being arranged on the front side or the back side of the auricle, and can be changed according to actual needs, which is feasible.

Another implementation possibility is to place the shell behind the ear and fall between the pinna and the skull. As shown in FIGS. 18A-18C, the present application adopts a front part 180 and a connecting structure 190 to achieve this arrangement.

The pre-auricular component 180 is used to be arranged on the front side of an auricle, and will engage with the physiological structure on the front side of the auricle, thereby achieving a fixed effect; the connecting structure 190 includes a pre-aural part and a Behind the ear part, the front part further has a first coupling part 191 for mechanically coupling with at least a part of the front part, and the back part further has a second coupling part 192 for connecting to the housing At least a part of 100 is mechanically combined, and a relative force is generated between the front part and the back part of the ear, and through this relative force, the housing can be fixed to the back of the auricle.

That is, after the preauricular component is engaged with the physiological structure of the front side of the auricle, the positioning effect is achieved, and thereby, the preaural part of the connecting structure mechanically combined with the preaural component can also be After being positioned on the auricle, through the relative force between the front part and the back part of the ear, the effect of positioning the housing located on the back side of the auricle and mechanically combined with the back part is achieved. When the housing can be stably arranged on the back of the auricle, it is positively helpful for the arrangement of physiological sensing elements and the acquisition of physiological information. Here, the physiological sensing elements that can be set include, but are not limited to, light sensors, accelerometers, electrophysiological signal acquisition electrodes, temperature sensors, and microphones.

Among them, it should be noted that, between the first coupling piece and the front part, and between the second coupling piece and the back part, can be implemented as an integral shape, or can be implemented in a removable form , Depending on the actual implementation situation, no restrictions.

There are various possibilities for the implementation of the preauricular component, and there are also various possibilities for engagement with the physiological structure of the auricle. For example, as shown in FIG. 18B, the preauricular component 180 can be implemented as having an inner ear part 181 and an extension rod 182, and the inner ear part 181 is engaged with the tragus, the notch between the tragus, and the antitragus Between, in order to achieve a fixed effect; or, as shown in Figure 18A, the pre-ear component 180 can also be implemented as having only the inner part of the ear, in this case, the inner part is preferably implemented to at least partially abut the auricle Physiological structure, for example, the concha wall, tragus, antitragus, etc. that abut the concha cavity and/or the concha boat, or engage with the ear canal to achieve a fixed effect; therefore, the preauricular component The form of implementation is not limited, as long as it can be combined with the physiological structure of the front side of the auricle to produce a card and achieve a fixed effect, it is the category claimed by this application. As for the mechanical coupling between the first coupling member 191 and the front part 180 of the connecting structure, it can be implemented without limitation to generate a mechanical coupling with the inner part 181 and/or with the extension rod 182. Combined, and further, can be implemented in a removable form, for example, the first coupling member can be implemented as a loop and removably coupled with the extension rod, or the first coupling member can also be implemented as A kit can removably cover the inner part of the ear at least partially. Therefore, there are various implementation options and possibilities without limitation.

This connection structure also has different implementations. In one embodiment, as shown in FIG. 18A, the connection structure 190 is implemented as a flexible connection structure, and the front part and the back part of the flexible connection structure are attracted by magnetic force to achieve the connection between the two Wherein, the front part of the ear further has a magnetic member 193, which is disposed between the first coupling member 191 and the second coupling member 192, and contains a magnetic substance to achieve magnetic attraction The other magnetic substance is placed behind the auricle, which can be implemented as being placed on the second coupling member 192 of the back part of the ear, or can be placed on the housing 100, wherein, when placed on the housing At this time, it can be implemented as being arranged inside the shell, embedded in the shell wall of the shell, or attached to the surface of the shell, etc., all feasible.

Therefore, through the magnetic attraction between the two magnetic substances, the magnetic member of the front part of the ear and the combination of the back part of the ear and the shell can generate relative force through the auricle, so as to make the shell The effect of the body being fixed to the back of the auricle.

The advantage of this embodiment is that as long as the size of the magnetic element is suitable, there is no restriction on the position of the magnetic element on the front side of the auricle. Therefore, the housing behind the ear can also be set at the best sampling position.

In another embodiment, as shown in FIGS. 18B-18C, the connecting structure 190 is implemented as an earhook structure, which is arranged between the auricle and the skull. In this case, when the earhook structure is in front of the ear When the first coupling member 191 of the ear is mechanically coupled with at least a part of the front part 180, one end of the ear hook structure is positioned, and then the second coupling member 192 of the behind the ear part is mechanically coupled to the housing 100, The housing positioning can be further achieved. As for the relative force between the front part of the ear and the back part of the ear, it is achieved by the elastic deformation characteristic of the ear hook structure, for example, plastic or memory metal can be used It can be made of other materials to provide the elastic deformation characteristics, thereby achieving a stable setting; in addition, the first coupling member 191 can be further implemented to be movable on the extension rod of the front part, for example, move up and down, and rotate Among them, by moving up and down, it can adapt to different auricle sizes and provide a fixed component of the housing downward, and by rotating, it can further provide a component of force that makes the housing closer to the skin, for example, towards The force component behind the auricle is therefore quite advantageous; in addition, the second coupling member 192 can also be further implemented to move and/or rotate on the behind the ear part of the earhook structure, for example, by using removable A silicone piece placed on the back of the ear, and this will help to set the housing and the physiological sensing element in the best position. For example, the housing can be moved to the most suitable position for sampling and can be used Rotating to adjust the contact angle between the shell and the pinna or the head is also advantageous. Here, it should be noted that, in addition to the earhook structure shown in Figure 18B, which is arranged between the upper auricle and the skull, it can also be implemented as shown in Figure 18C, which is arranged between the lower auricle and the skull, without limitation. .

Furthermore, no matter what kind of connection structure is adopted, the front part can be implemented as an earphone, for example, a wired or wireless earphone. In this way, the user's existing earphone can be directly used as a support to set up the application. The miniature housing is not only convenient, but also cost-effective; and, furthermore, the headset can also be implemented to generate audio based on the obtained physiological information and provide it to the user, for example, to notify the user that the preset physiological Status, such as the heart rate reaching a preset value, or a preset sleeping posture, etc., and the way to generate audio can be implemented as, for example, if it is a wireless headset with a control unit, such as a smart headset, it can be directly connected with the micro The control units in the housing communicate wirelessly and determine audio through pre-loaded programs with each other, or, if it is a wired or wireless headset controlled by a computer device or a portable electronic device, for example, a mobile phone or computer connected Wired or wireless earphones can determine the audio by wirelessly communicating with the pre-loaded program in the computer device or portable electronic device through the pre-loaded program of the control unit in the miniature housing of this application. Therefore, there are various possibilities without limitation .

So far, it can be seen that in the case that the miniature housing of the present application has a sufficiently small volume, even ears with limited installation space can be installed well and stably as long as they are matched with different wearing/ear wearing structures. When the applied casing is combined with the above-mentioned multiple ear-wearing structures, an ear-wearing physiological system is formed, which can cover most of the sampling positions on the ear, and the use of different physiological sensing elements is equivalent to a complete set. Positional system.

In actual implementation, the ear-worn physiological system will include a miniature ear-worn physiological device and a plurality of ear-worn structures. The miniature ear-worn physiological device, as described above, includes a housing, a control unit, and a physiological sensor. Components, communication modules, batteries, etc., the multiple ear-wearing structures at least include a first ear-wearing structure and a second ear-wearing structure, but are not limited, and can also be implemented as more than two ear-wearing structures, For example, three or four, and here, the ear-wearing structure can be any of the aforementioned wearing structures where the housing can be placed on or near the ear, for example, an in-ear maintenance structure, a magnetic attraction structure, and a front part and connection Structure, adhesion structure, attachment base structure, electrical extension base structure, etc. Therefore, the position where physiological information can be obtained is not limited, and it can be any part of the auricle, or it can be the skull, without limitation.

The housing and each ear-wearing structure are implemented in a removable form. In this way, the user can selectively combine with the appropriate ear-wearing structure according to different usage habits and usage requirements, and obtain Corresponding physiological information, for example, if you use it during exercise, you can choose a connection structure with earphones, or a magnetic structure, or you can choose a wearable structure at the back of the auricle; if you use it during sleep, you can choose the ear Maintain the structure to avoid discomfort caused by side sleeping; if the user is in daily life, he can choose according to his personal usage habits. In addition, there may also be situations where the user is unable to adapt to one or some ear wear structures, for example, unable to adapt to a shell clipped on the auricle, and through this system, the user can be freely provided with other The choice is quite advantageous.

Alternatively, it can also be selected according to the physiological information to be obtained. For example, when the blood oxygen concentration is to be obtained, it is better to install the light sensor on the earlobe, the bottom of the concha cavity, or the position behind the ear corresponding to the cerebral cortex. When the heart rate is obtained, the light sensor can be arranged at any position on the ear, and in particular, in order to respond to the change in the sampling position caused by the replacement of the ear wear structure, the light sensor can be further implemented as having three types as described above The light source provides three wavelength combinations to provide the best sampling wavelength combination for different blood physiological information; to obtain physical activity information, sleep posture, and/or snoring related information, an accelerometer and/or microphone are required Set on the ear/near the ear to obtain physical activity, to obtain sound, and/or to detect the position of snoring body cavity vibration; to obtain electrophysiological signals, such as brain electrical signals, ECG signals, electromyographic signals, and skin electrical signals Etc., the electrode located on the housing can be implemented as a reference electrode for obtaining various electrophysiological signals, and can be set at any position of the ear, and if other electrodes need to be extended from the housing, they can be set on the same auricle , Another pinna, or skull. The relevant settings and usage details, as well as other setting possibilities, are as listed in the foregoing various physiological sensing elements and various wearing structures, and will not be repeated.

Therefore, such a concept not only allows the same micro-physiological device to maximize the benefits of the ear setting position, but also provides users with the most diverse choices, which helps increase the willingness to use and increase the popularity of use, which is quite advantageous.

In addition to combining different ear-wearing structures and setting them at different positions on the ear/near the ears, other body positions can also be changed by changing the wearing structure, for example, on fingers, wrists, soles, ears, torso, Switching between positions near the mouth and nose, forehead, etc., will provide a multi-functional wearable physiological system.

Among them, in particular, when a light sensor is used, additional implementation options can be provided according to the number of light sources provided and the wavelength. As mentioned above, if you want to obtain heart rate and other blood physiological information, such as breathing behavior, you need to include at least one luminous source, while you want to obtain blood oxygen concentration, you need to include at least two luminescent sources, and the best sampling results are obtained in both cases Suitable wavelength combinations are different. Therefore, in the embodiment provided by the present application that the different installation positions can be changed by changing different wearing structures, it is preferable that the three types of light-emitting sources as described above are set at the same time. Regardless of the setting position, blood physiological information can be obtained smoothly, which not only increases the convenience of use, but also improves the efficiency of use.

For example, the wearable physiological system may include a miniature wearable physiological device and at least one first wearable structure and a second wearable structure, wherein the miniature wearable physiological device includes a housing, a control unit, a communication module, a battery, and In particular, at least one first light-emitting source, at least one second light-emitting source, at least one third light-emitting source, and at least one photodetector, wherein the at least one first light-emitting source produces a light-emitting source with a first wavelength combination Light, the at least one second light source generates light with a second wavelength combination, the at least one third light source generates light with a third wavelength combination, and the at least one photodetector is received from the at least At least one of the light emitted by a first light source, the at least one second light source, and the at least one third light source.

The shell can be selectively combined with the first wearing structure or the second wearing structure to be disposed in a first body area or a second body area, wherein when disposed in the first body area, the control unit will A first blood physiological information is obtained through the first light source, the second light source, and the at least one light detector, and when set in the second body area, the control unit will pass the third light source The light source and the at least one light detector obtain a second blood physiological information.

Wherein, the first blood physiological information is implemented to include blood oxygen concentration, and blood physiological information that can be obtained through the first light-emitting source, the second light-emitting source, and the light detector. According to this, the first body area includes, but It is not limited to the positions of the forehead, between the nose and mouth, ears, fingers, and soles of the feet; in addition, the second blood physiological information includes various blood physiological information that can be obtained through a third light source and a light detector, such as heart rate , Breathing behavior, etc., and the second body area includes body parts such as the head, torso, and limbs.

In actual implementation, for example, the first wearing structure can be implemented as a finger-wearing structure and the blood oxygen concentration can be obtained from the fingertips, or the second wearing structure can be implemented as a magnetic attraction structure and the heart rate can be obtained from the auricle. Blood physiological information; alternatively, the first wearable structure can be used to attach the base structure to obtain blood oxygen concentration on the forehead, or the second wearable structure can be used to implement the adhesion structure to obtain heart rate and other blood physiological information on the torso; alternatively, it can be used The first wearing structure is implemented as an adhesion structure to obtain blood oxygen concentration between the mouth and nose, and the second wearing structure can also be implemented as a wrist-worn structure to obtain heart rate and other blood physiological information from the wrist. Therefore, various forms of wearing structures can be used, and are not limited to the above, for example, the various forms of wearing structures mentioned in this article, or various existing commonly used wearing structures, such as headbands, chest straps, patches, etc. , Are unlimited.

Of course, it is also applicable to different parts of the same physiological structure. For example, the first wearing structure can be used to obtain blood oxygen concentration on the earlobe, and the second wearing structure can also be used to obtain heart rate and other blood physiological information in the ear, or, The first wearing structure can be used to obtain blood oxygen concentration at the fingertips, and the second wearing structure can also be used to obtain heart rate and other blood physiological information on other knuckles.

It can be seen from this that in actual implementation, there is no restriction on the setting position, and no restriction on the wearing structure, as long as the blood oxygen concentration, heart rate, and other blood physiological information can be obtained on the body, and the aforementioned various wearing structures ( The position where the micro-shell is arranged (including the ear-wearing structure) is within the scope of this application.

In another aspect, the miniature physiological device of the present application can also obtain physiological information during sleep. Due to the small size of the housing, coupled with a suitable wearing structure, even if it is used during sleep, it will not cause a burden to the user. In the past, the situation where it is difficult to fall asleep due to various physiological sensing elements will be significantly improved. Therefore, it is indeed a very suitable choice for use during sleep.

When used during sleep, it is often used to check whether sleep breathing disorder occurs. One type of sleep breathing disorder is sleep apnea (Sleep Apnea), which is generally divided into three types: obstructive sleep apnea (Obstructive Sleep Apnea) , OSA), Central Sleep Apnea (Central Sleep Apnea, CSA), and Mixed Sleep Apnea (Mixed Sleep Apnea, MSA). Among them, the main feature of Obstructive Sleep Apnea (OSA) is that during sleep due to Complete or partial obstruction of the upper airway results in a decrease or cessation of respiratory airflow for a period of time. Central sleep apnea (CSA) is caused by problems in the brain driving muscles to breathe, which will shorten the nerve drive of the respiratory muscles. The stop of time, mixed sleep apnea (MSA) refers to a situation where both obstructive sleep apnea and central sleep apnea are mixed; there is another common sleep breathing disorder called snoring, which produces noise Symptoms are caused by the vibration of the soft tissues when the upper airway airflow passes through during sleep.

OSA and severe snoring have been confirmed by research to be highly correlated with many clinical symptoms, such as daytime sleepiness, depression, the formation of hypertension, ischemic heart disease, cerebrovascular disease, etc., and snoring is the most common occurrence of OSA. Symptoms and snoring are also generally considered to be precursors of OSA. The causes of both are related to the physiological phenomenon of upper respiratory tract stenosis.

According to research, as the degree of upper airway stenosis evolves, it is usually the case that snoring symptoms related to sleeping postures occur first, and when it is more serious, snoring is prone to occur even when not lying on your back, and begins to develop into mild snoring. And the correlation between the occurrence of snoring and sleep posture has gradually decreased. Furthermore, the severity of OSA has also changed from mild to moderate, which is related to sleep posture, and finally becomes severe, which is less related to sleep posture.

Sleep positional training (SPT) is a method that can improve postural OSA and postural snoring. In recent years, a new generation of posture training devices has been developed, which can be applied to appropriate positions on the body, such as the head and neck. , Chest or abdomen, set up a posture sensor, such as an accelerometer, and when it detects that the user’s sleeping position is lying on his back, a weak vibration warning is generated to prompt the user to change his sleeping position to avoid lying on his back. Many research reports have pointed out that this simple but effective way can prevent patients from lying on their backs during sleep, thereby greatly reducing the number of OSA events.

The micro-physiological device of the present application is suitable for the detection of sleep disordered breathing or for sleep posture training.

For example, the blood oxygen concentration obtained by the optical sensor can be used to obtain important indicators for evaluating or detecting sleep apnea, the oxygen desaturation index (ODI) and hypoxia level, and the heart rate and DC component obtained by the PPG signal It can be used to derive breathing behavior to understand the changes in sleep breathing; impedance detection electrodes, accelerometers, piezoelectric motion sensors, RIP sensors, etc. can obtain breathing motions to understand the fluctuations of the chest and abdomen; accelerometers, microphones, piezoelectric vibrations Sensors, etc. can obtain snoring related information; accelerometers can be used to obtain sleep posture, sleep physical activity information, etc., and further obtain sleep stage/state related information, temperature sensors can obtain body temperature information, and electrophysiological signal capture electrodes can obtain eye electricity Signals, brain electrical signals, and then determine the stage of sleep, can also obtain ECG signals to understand the heart activity during sleep. Moreover, since the casing is quite small, it is not limited to only a single device, and it can also be installed on multiple parts of the body at the same time to obtain a variety of physiological information, which helps to more accurately determine sleep physiological information.

When applied to sleep posture training, only a tactile warning unit, such as a vibration module, that is electrically connected to the control unit is added to the housing to provide tactile warnings, such as vibration warnings, required to change postures. Moreover, this application The micro-physiological device of is originally set on the body surface, for example, it is set up with an adhesive structure, and has a protruding edge as described above to help the device fit the skin more, which will enable tactile warnings to be transmitted to the human body more effectively , So that the effect of sleep posture training is more significant. As for the implementation details of the prominent edge, since it has been described in detail above, it will not be repeated here.

The main basis for sleep posture training is sleep posture. In this application, the sleep posture related information is obtained by using an accelerometer. The obtained position is the appropriate position of the body, including the top of the head, forehead, ears, nose and mouth, and chin. The neck, chest, and abdomen, and can be set on any body surface of the body, for example, the front, back, etc., as long as the sleeping position can be obtained by conversion. Among them, the torso and the neck above the torso The most representative.

The posture training method is that when it detects that the sleeping posture meets a preset posture range, for example, lying on the back posture, and continues for a period of time (for example, 5 seconds to 10 seconds), the tactile alert unit will activate the tactile alert, and the The tactile alert will gradually increase/increase its intensity until it detects that the sleeping posture is out of the preset posture range, for example, it changes to a different sleeping posture or a non-recumbent posture, then the alert stops immediately. If a preset period ( For example, if no posture change is detected after an adjustable 10 seconds to 60 seconds), the alert will be paused and restarted after a period of time (for example, an adjustable number of minutes); in some embodiments, the tactile sensation The frequency/duration of the warning will be very short at the beginning, and will gradually increase until the user no longer presents the lying position; no matter the strength of the warning, there will be repeated several times (for example, 2 seconds) between warnings ( For example, 6 times).

As for the setting of the preset posture range, it can be different according to actual needs. For example, according to the definition of the lying posture, the preset posture range will be changed.
