Detailed ways

In the concept of the present utility model, in order to achieve the purpose of multi-purpose, the method adopted is to concentrate the circuits, components, and physiological sensing elements required for physiological signal detection on the same housing as much as possible, so that In the future, just by changing the wearing structure, the setting position or setting method of the shell can be easily changed to obtain different physiological signals.

Accordingly, according to the multi-purpose physiological detection device of the present invention, there is a housing as the main body, which is mainly used for accommodating circuits/components and setting physiological sensing components. As shown in FIG. 1, the multipurpose physiological detection device according to the present invention will include a physiological signal acquisition circuit 110, and be electrically connected to physiological sensing elements, such as electrodes and/or light sensors, to obtain physiological signals, Here, it should be noted that the physiological signal acquisition circuit will include all necessary circuits and components for obtaining physiological signals, such as processors, analog signal processors, analog-to-digital converters, filters, memory, Batteries, etc. are well known to those skilled in the art, so they will not be described in detail; in addition, if there is a need for wireless transmission, for example, when used to transmit the obtained physiological signal to an external device, a wireless transmission module can also be included , or, memory can also be implemented in a removable form. Therefore, different circuits, components, and/or modules can be provided according to actual needs, all of which belong to the scope of the present invention without certain limitations.

As for the type of the physiological sensing element used, there is no certain limitation, and it can be determined according to actual needs. For example, only at least two signal acquisition electrodes may be included to obtain electrophysiological signals, such as ECG signals, EEG signals, oculoelectric signals, myoelectric signals, electrodermal signals, etc., or only light sensors may be included , to obtain blood physiological information, for example, when there is one light source, heart rate, blood flow, etc. can be obtained, and when there are more than two light sources, blood oxygen concentration can be obtained, of course, it can also include signal acquisition electrodes and Light sensors, therefore, have no limitations.

Here, it needs to be explained that, in general, when picking up electrophysiological signals, signal picking electrodes and grounding electrodes are usually set up. Among them, the signal picking electrodes are used to get electrophysiological signals, and the function of grounding electrodes is to remove the background Noise, and all the electrodes described in this article belong to the signal extraction electrodes. However, in order to avoid too long words, in the following descriptions, "electrodes" are used to represent "signal extraction electrodes". As for the ground electrode Generally, the settings are selectively set according to actual needs, so they are omitted in this article. In addition, to make the description more concise, when the electrodes are used to obtain specific types of electrophysiological signals, the Electrodes that are directly described as this type of electrophysiological signal, for example, electrocardiographic electrodes, electroencephalographic electrodes, electroocular electrodes, electromyographic electrodes, electrodermal electrodes, etc.

Moreover, the electrodes described here are generally known conductive materials that can sense the spontaneous potential difference of the human body, such as metal, conductive fiber, conductive rubber, conductive silica gel, etc., so in the following description, only The installation position, installation method, shape, etc. of the electrodes will be described.

In addition, a light sensor refers to a sensor that has both a light-emitting element and a light-receiving element. It emits light through the light-emitting element and enters the human body tissue, and the light is absorbed by the light after penetrating the blood in the blood vessel or reflected by the blood. After being received by the receiving element, blood physiological information is obtained by obtaining the volume change caused by the light.

Generally speaking, when it is implemented to obtain blood physiological information through penetration, as shown in FIG. When obtaining blood physiological information by means of reflection, as shown in Figure 2B, the light-emitting element and the light-receiving element will be arranged on the same side of the measurement site, such as a finger. In addition, when the setting position is between the above two positions , depending on the actual situation, it may be in the way of penetration and/or reflection.

In addition, even in the form of a replaceable wearable structure, without limitation, physiological sensing elements can also be arranged on the wearable structure, and the benefits brought by this can be achieved by replacing the wearable structure, for example, Various options such as changing the type of physiological sensing elements, increasing or decreasing the number of physiological sensing elements, and changing the location of the physiological sensing elements are also quite advantageous, and the detailed implementation will be described later.

First of all, in the conception of the first aspect of this case, a multi-purpose design based on fingers was chosen.

The advantage of choosing the finger-worn form is that this position is widely accepted in daily life. Many people have the habit of wearing rings. There is no need to adapt, and it is not obtrusive during use.

As shown in FIGS. 3A-3B , a finger-worn structure 200 carries a casing 100, and physiological sensing elements, such as electrodes and/or light sensors, are arranged on the casing, wherein, when implemented as electrodes, Both electrodes 120 can be placed on the surface of the casing that will be in contact with the finger (as shown in FIG. 3A ) to obtain skin electrical signals, electromyographic signals, etc.; or as shown in FIG. 3B , one electrode 120 can be placed On the surface that will be in contact with the finger, and another electrode 120 is placed on the surface that is not in contact with the finger, so as to obtain ECG signals by contacting different parts of the body respectively; in addition, when implemented as an optical sensor, Then, the light sensor can be arranged on the surface of the shell facing the finger, and ensure that the light used for sensing can enter the finger, so that blood physiological information can be obtained from the finger through the light sensor during the wearing process, or, also The optical sensor can be arranged on the outward surface of the casing, and blood physiological information can be obtained by contacting other body parts, for example, the other hand; moreover, it can also be implemented by setting electrodes and optical sensors at the same time, in this case Next, the configuration of the electrodes and the photosensors can be combined in various ways according to actual needs, and there is no certain limit.

Therefore, very conveniently, the user only needs to put on the ring to carry out the physiological detection, and because the form of the ring hardly interferes with daily life and is not obtrusive, it is very suitable for use in daily life.

Here, the form of the finger-worn structure is not limited, as long as the shell can be maintained on the finger and the physiological sensing element can be set at the same time, for example, it can be a ring structure, a C-shaped structure, etc., for example, Ring structure, finger clip structure, finger cuff structure, strap structure, etc. are all available methods. In addition, the material can also have different choices. For example, it can be implemented as a hard material, such as plastic, metal, etc., and can also be implemented Soft materials and/or elastic materials, such as silica gel, rubber, cloth, etc., are all feasible ways, that is, the above-mentioned various finger-worn structures can be made of hard materials, Or soft/elastic material, or mixed material to make, there is no limit.

Next, as long as the housing is detachable from the finger-wearing structure, it can be used for multiple purposes. One of the options is to place it on other parts of the body through another wearing structure. For example, it can be set on the torso through a patch structure or a neck wear structure. The electrodes can simultaneously touch the trunk to obtain electrocardiographic signals, electromyographic signals, and/or electrodermal signals, or the electrodes arranged on the opposite surface can respectively contact the hand and the trunk by pressing with one hand to obtain electrocardiographic signals. The optical sensor can obtain blood physiological information from the torso or from the hand in contact; or, it can also be installed on the wrist through a wrist-worn structure, whether it is an electrode or an optical sensor, it can smoothly obtain various physiological signals/information For example, electrodes on the opposite side can obtain ECG signals by contacting the wrist and another part of the body, such as the other hand, or the torso, while electrodes placed on the same surface can obtain muscle signals from the wrist. Electrical signals, electrodermal signals, etc., and because it was originally implemented as a finger-worn form, when the case is placed on the wrist, the volume will be very small, similar to the feeling of a bracelet, and the burden is quite small.

Another option is to change the size of the finger-wearing structure to adapt to different finger sizes or fingers of different users, especially when the finger-wearing structure is implemented as a ring form, such as a ring, due to its rigidity The structure has its limitations for the adaptation of different fingers. Therefore, if rings of different sizes can be replaced, a single device can be easily adapted to fingers of different sizes. In this way, except for the same user can freely choose to set In addition to fingers, different users can also share the same device, which is quite cost-effective.

In actual implementation, one of the implementations is that the replaceable finger-worn structure is implemented as a simple structure without physiological sensing elements. In this case, the electrodes used to perform physiological detection, light sensors, physiological The signal acquisition circuit, etc., are all set in the shell that can be combined with the finger-wearing structure, that is, the shell and the finger-wearing structure are only mechanically combined, wherein the optical sensor can be set in the shell When the body is combined with the finger-wearing structure, the direction facing the fingers or the direction facing outwards, and the electrode settings are different according to the physiological signals obtained. For example, if it is used to obtain ECG signals, a One electrode is in contact with the finger, and the other electrode is exposed for contact with other parts of the body. If it is used to obtain EMG and/or galvanic skin signals, two electrodes need to be on the same surface, for example, contact the finger at the same time, or be exposed and exposed at the same time. contact with other parts of the body.

Furthermore, another implementation option is that the replaceable finger-wearing structure is implemented with physiological sensing elements, for example, light sensors and/or electrodes. , it is also necessary to achieve an electrical connection, so that the physiological sensing element on the finger-worn structure can be electrically connected to the physiological signal acquisition circuit in the casing. Here, it should be noted that the physiological sensing element on the finger-worn structure can be a light sensor, or a single electrode to cooperate with the electrodes on the housing, or it can also be two electrodes, so it can be used according to the design Varies with no limits. As mentioned above, the optical sensor includes a light-emitting element and a light-receiving element. Therefore, when it is arranged on the finger-worn structure, it can be selected to obtain blood physiological signals by means of penetration or reflection. Both are feasible.

In addition, in a special embodiment, another special implementation can be produced by changing the material of the finger-wearing structure. When the finger-wearing structure is implemented as a metal material, as shown in Figure 3C, for example, a common stainless steel ring, the metal finger-wearing structure can be made to contact one of the electrodes on the original housing by making the finger-wearing structure contact with one of the electrodes on the original shell. The wearing structure becomes the extension of the electrode. In this way, the action of setting the finger-wearing structure is equivalent to setting the electrode, and the contact area is also increased, which is quite convenient. In addition, another electrode is located on the exposed surface of the shell. Therefore, such a setting is particularly suitable for capturing ECG signals. The advantage brought by this is that the structure of the finger-worn structure becomes quite simple, and there is no need to set up additional electrical connecting wires and electrodes, the manufacturing procedure can be simplified to the greatest extent, and the manufacturing cost can also be reduced.

In this case, it should be noted that the material of the finger-worn structure is not limited to metal, as long as it is conductive and can be combined with the shell and placed on the finger, it is a feasible choice, for example, conductive rubber, Conductive silica gel, conductive ceramics, conductive fibers, etc. are not limited, and are not limited to being made of only one material. For example, metal can be covered with other materials to create visual effects. Therefore, as long as it can The conductive material constitutes the main body of the finger-wearing structure, for example, as a support, which belongs to the category of the present invention.

Furthermore, when it is only necessary to provide ECG signal measurement, it can also be directly implemented in a form in which the conductive finger-wearing structure and the housing are inseparable, so that the housing is fixed on the finger-wearing structure. Come, it will be more cost-effective.

In another aspect of the conception of this case, the choice is the choice of multi-purpose settings based on the head.

As we all know, the head can also obtain quite a lot of physiological information, such as EEG signals, eye movement signals, myoelectric signals, brain blood flow (HEG, hemoencephalography), etc., so it is especially suitable for obtaining sleep physiological information during sleep. Information such as status or sleep quality, or used during physiological feedback and neurophysiological feedback, under this premise, if it is possible to provide the option of setting it at other body positions to obtain other physiological signals, it is naturally another for users. One bullish.

Accordingly, in this embodiment, as shown in FIGS. 4A-4B , the physiological sensing element is arranged on the lower surface 101 of the housing. For example, FIG. 4A shows the situation where two electrodes 120 are set, and FIG. sensor 122, and in this way, physiological signals can be obtained from the head by using the arrangement shown in FIG. 5, for example, in FIG. Electrical signals, etc., and Figure 4B can obtain brain blood flow, blood oxygen concentration, etc., and in this case, as mentioned above, the optical sensor will use reflection to obtain blood physiological information. In addition, further , it can also be implemented to arrange electrodes and light sensors at the same time to obtain more physiological signals. For example, it can be implemented that electrodes and light sensors are arranged on the same plane or on different planes, and there is no limitation.

Here, the shell set on the head is set by a head-wearing structure, for example, it can be straps, helmets, hats, glasses, patches, glue, etc., which are all optional forms. In addition, In particular, the headgear structure can also be implemented to have an electrical conduction function, for example, implemented as an adhesive that is directly attached to the electrodes and can help conduct electricity, or implemented as a conductive patch that is combined with the electrodes on the shell , for example, a patch electrode combined with a metal interlocking method, for example, a button patch electrode. Therefore, there is no limitation, as long as the shell can be arranged on the head, all belong to the scope claimed by this case.

Next, when it is intended to be arranged at other positions, according to the design of the positions of the electrodes and the light sensor on the casing, any arrangement is feasible as long as the electrode and the light sensor can contact the skin.

Among them, when implemented as a light sensor, it can be installed on the wrist to obtain blood physiological information from the wrist, such as blood oxygen concentration, heart rate, etc., or it can also be installed on the forearm or upper arm to obtain The above-mentioned blood physiological information can be set on the finger by combining it with the finger-worn structure, especially the finger has always been the most commonly used position to obtain the blood physiological information. The sensor does not touch the skin. At this time, the blood physiological information can also be obtained by touching the light sensor with the other hand. Alternatively, the housing can be positioned in front of the torso by means of a neck-worn structure, in which case the light sensor can be implemented towards the torso in contact with the torso or towards the outside in contact with the hand.

When it is implemented as an electrode, it can also be placed on the wrist, forearm, upper arm, etc., and the two electrodes 120 contact the skin at the same time to obtain skin electrical signals, electromyographic signals, etc., or it can be installed in front of the torso through a neck-wearing structure. , through the two electrodes 120 contacting the skin of the torso at the same time to obtain the ECG signal.

In this way, whether it is an electrode or a light sensor, when it is placed on the head, it can obtain the physiological signals of the head, such as EEG signals, electro-ocular signals, skin electro-signals, myo-electric signals, and brain blood flow , and blood oxygen concentration, etc., and when it is installed on the finger, wrist, upper arm, forearm, and front of the torso, it can obtain cardiovascular-related signals, such as blood oxygen concentration, heart rate, ECG, etc., and others Physiological information, such as electrodermal signals, and electromyographic signals.

Therefore, through such a design, even the same device can obtain a wide variety of physiological signals as long as it is matched with different wearing structures and installed on different body parts, which is quite advantageous for users. s Choice.

In yet another aspect of the conception, the physiological detection device in the form of an earphone is selected.

Earphones are already an indispensable accessory in the daily life of modern people. Therefore, more and more physiological detection devices are implemented in the form of ear wear. In addition to allowing users to use them naturally, it also makes physiological detection more integrated into daily life. For example, the ear-worn form is well suited for various procedures such as sleep physiological monitoring, cardiovascular monitoring, physiological feedback, neurophysiological feedback, and more.

Furthermore, when it is implemented in the ear-wearing form, it can also naturally provide earphone functions by combining sound-generating components, which not only improves the willingness to use, but also helps to perform physiological feedback and neurophysiological feedback through sound, which is quite advantageous. Therefore, the ear-mounted earphones described herein can be various types of earphones available on the market, for example, wired earphones or wireless earphones, ear canal earphones, earplug earphones, ear-hook earphones, neck-hung earphones, Headphones, etc., are not limited, as long as they meet the following conditions, they all fall into the scope of this case, and the way of providing sound can also be changed according to the different forms of headphones, for example, The sound of wired earphones mostly comes from the portable electronic device connected to it, while the sound of wireless earphones may be received through Bluetooth connection, or directly stored with recording files, MP3, etc. There are various possibilities.

Based on this, one embodiment of the multi-purpose physiological detection device provided by the present invention is that, as shown in Figures 6A-6C, the form of double ear wearing includes a first ear wearing structure 310 and a second ear wearing structure 310. The ear-wearing structure 312, the physiological signal extraction circuit can be set in the first ear-wearing structure, or in the second ear-wearing structure, or separately placed in the two ear-wearing structures, or another housing can be provided To set the circuit, as shown in Figure 6C, in this case, the other housing can also be used to set control buttons, etc., so there is no limit. In addition, one electrode is respectively set on the two ear-wearing structures, the electrode 330 and the The electrode 332, and the two ear-wearing structures are connected to each other through a connecting wire 314, so as to realize the electrical connection between the electrode 330, the electrode 332, and the physiological signal acquisition circuit.

Here, it should be noted that the setting method and position of the electrodes will be different according to the measurement signal. For example, the electrodes can be set at the position in contact with the ear skin, or at the position not in contact with the ear skin. In addition, in addition to the method of additionally adding electrodes on the surface of the ear-wearing structure, for example, setting electrode sheets, it can also be implemented in other forms, for example, the surface of the ear-wearing structure can be directly implemented as electrodes, for example, using The method of coating the conductive layer, or directly using conductive materials (such as conductive rubber, conductive silica gel, etc.) to form the part, therefore, there is no limit, as long as it is located on the surface of the ear-wearing structure, the extraction of electrophysiological signals can be achieved. All belong to the category of the present utility model. In addition, especially since the structure of the ear is complex and the structure of each individual is different, it is preferable to implement a single electrode as multiple small-area contact points in order to increase the achievement of contact. Possibilities, for example, can be implemented as electrodes with multiple needle-like structures, and, furthermore, can be implemented with telescoping elasticity, for example, using metal spring connectors (pogo pins) as electrodes to accommodate the undulations of the ear structure Changes, as well as differences between different users, increase the contact stability. Among them, the electrode with multiple needle-like structures has different implementation options. For example, it can be formed by soldering multiple conductive needle-like structures on the circuit board. It can also be an integrally formed conductive base and a plurality of conductive needle-like structures, no matter what the form is, there is no limit, as long as it can provide multi-point contact and form an electrical connection with the physiological signal acquisition circuit, and then obtain the electrophysiological signal. Signal is enough, there is no limit.

In FIGS. 6A-6C , the electrode 330 is placed at a position where it will contact the ear and/or the skin of the nearby area when the first earwear structure is placed on an ear, and the electrode 332 is at the position where the second earwear structure is placed on the ear. The setting position on the ear-wearing structure can vary according to different usage situations. For example, Figures 6A and 6C show that the electrode 332 is located at a position that does not touch the skin near the ear, and Figure 6B shows that the electrode 332 is located at a position that can be contacted. to the skin of the ear.

In one way of use, the first earwear structure is placed on the ear, while the second earwear structure is taken off. In this case, one option is that the electrode 332 contacts the chest to obtain the heart projection angle formed by the ear and the chest, another option is that the electrode 332 contacts a hand holding the second ear-wearing structure, or The second ear-wearing structure is held by the hand, and then the electrodes are brought into contact with another upper limb, so as to obtain the heart projection angle between the ear and an upper limb. The difference between the two options is that the obtained heart projection angles are different, and also because of the design of the connecting wire, the user can freely select a suitable and desired measurement position to obtain the best ECG signal.

In another usage mode, both the first ear-wearing structure and the second ear-wearing structure are removed. In this case, one option is to have both electrodes touch the chest, and another option is to have both electrodes touch each hand. Likewise, these two options can obtain the chest-to-chest heart projection angle and the heart projection angles of both hands respectively.

In yet another usage manner, both the first ear-wearing structure and the second ear-wearing structure are placed on the ear to obtain ECG signals. When the configuration shown in Figure 6A is implemented, the contact between the upper limb and the electrode can be achieved by lifting the hand, as shown in Figure 7A, which is also quite convenient; Electrodes are arranged on the exposed surfaces. In this way, as shown in FIG. 7B , ECG signals can be obtained by touching the two electrodes respectively arranged on the exposed surfaces with both hands.

Furthermore, it can also be implemented that each ear-mounted structure is provided with electrodes in contact with the ear and electrodes on the exposed surface. The exposed electrodes can cooperate with the electrodes on the ear-wearing structure on the other side (right or left) to form sampling circuits respectively. The advantage of this method is that the ear-worn structure does not need to be removed from the ear to capture another ECG signal, and the left hand is raised to touch, the right hand is raised to touch, or both Touching both hands together, the obtained heart projection angles are all different, which can meet different application requirements. Furthermore, in the case where electrodes are provided both inside and outside, since the contacts for obtaining ECG signals are all achieved by electrodes on different ear-wearing structures, the inner and outer electrodes of the same ear-wearing structure can be further implemented as continuous distribution. The same electrode, in this way, will reduce the manufacturing complexity and help reduce the manufacturing cost.

In addition, in a special embodiment, two electrodes are respectively arranged on the exposed surfaces of the first ear-wearing structure and the second ear-wearing structure. ECG signal measurement, and in this case, because the exposed surface has a relatively large contact area, it also makes it easier to remove the ear-worn structure from the ear and contact the upper limb or torso. Therefore, there are various implementation possibilities in response to various usage requirements, without limitation.

Here, it should be noted that although the above-mentioned embodiments mainly take the form of an in-ear shell as an example, it is not limited thereto, and the ear-wearing structure can be implemented in various forms, for example, an ear clip structure, an ear-hook structure, Or a combination of ear-wearing structures, for example, an in-ear shell plus an earhook structure, or an ear clip plus an in-ear shell structure, etc., as long as they can provide stable contact, they are all feasible options. Moreover, two ear-wearing The structure can also be implemented in different types, for example, one side can be implemented as an ear clip, and the other side can be implemented as an in-ear shell, so there is no limitation.

Since the two ear-mounted structures are connected by connecting wires, when at least one ear-mounted structure is implemented to be used off the ear, the contact position of the electrodes becomes very variable, for example, the range of accessible connecting wires Therefore, it is possible to obtain the ECG at each position of the 12-lead electrocardiogram, so compared with the large number of electrodes and the number of connecting wires required to obtain the traditional 12-lead electrocardiogram, this design is equivalent to greatly reducing the In addition to setting the complexity and implementing the threshold, it is quite helpful to achieve a correct and detailed judgment on the heart in a simpler way.

Furthermore, in addition to the aforementioned self-measurement by the user, based on the particularity of the structure, the design of two ear-worn structures with connecting wires can also be applied to obtain other people's ECG signals. For example, the first ear-wearing structure can be placed on another person's ear, and the electrodes can be brought into contact with the ear and/or the nearby skin, and then the electrodes can be brought into contact with the other person's torso by holding the second ear-wearing structure, or In this way, the upper limbs can obtain the ECG signals of others, which is very convenient. Here, the ear clip structure is a particularly suitable choice for the first ear-mounted structure, which can easily achieve the operation of arranging the ear-mounted structure on other people's ears.

Furthermore, such a device can also be used to obtain EEG signals. In any of the above-mentioned configurations, as long as both ear-wearing structures have electrodes that can contact the ears and/or nearby skin, they can be used to obtain EEG signals, so that the same device can provide ECG signals The acquisition of the electroencephalogram signal and the acquisition of the EEG signal have two functions. Moreover, the ECG signal can also provide the choice of different projection angles, which is very advantageous. Among them, when the EEG signal is acquired, the contact position of the electrode is not specified. However, it is better to choose the electrode that touches the lower half of the auricle, for example, the tragus, below the tragus, the earlobe, the lower half of the concha wall, etc., as a reference electrode, which will be more conducive to obtaining Clear EEG signals.

Furthermore, in addition to setting electrodes, optical sensors can also be set through the ear-worn structure, for example, can be set on one side or both sides to obtain blood physiological information, such as blood oxygen concentration, heart rate, etc. In addition to the ECG signal, other physiological signal options can be provided. Here, similarly, the light sensor will obtain blood physiological information in a reflective manner. In addition, alternatively, when the implementation is to obtain the ECG signal by touching the electrode with the hand In the case of the number, the blood physiological information can be further obtained by the hand, for example, the contact with the light sensor can be achieved while touching the electrode, and in this case, since the ECG signal can be obtained through the electrode and the sensor through the sensor Heart rate, so the pulse transit time (PTT, Pulse Transit Time) can be obtained through the correlation between the two physiological information, and then information such as blood vessel hardness/elasticity can be obtained, and blood pressure can also be further estimated through calculation Related values have further meaning.

On the other hand, when the light sensor is implemented in the ear and/or near the ear, it is suitable for continuous detection, especially heart rate, for example, for heart rate monitoring during exercise, but also for long-term attention to the heart. Active patients, and through the multi-purpose design of this case, when there is a special need, for example, when the heartbeat suddenly feels abnormal, or the heart feels uncomfortable, the user can immediately touch the electrode by raising his hand, or take the ear-worn structure Touching the trunk or hands to record real-time ECG signals is very helpful for correctly judging related heart problems.

Moreover, according to another implementation concept of the present invention, a single ear-wearing structure can also be used for multiple purposes. As shown in FIGS. 8A-8B , a single ear-wearing structure is provided with two electrodes 330 and 332 .

In a preferred embodiment, as shown in FIG. 8A, when the ear-wearing structure is worn on the ear, the electrodes 330 will contact the ear and/or the nearby skin. The electrodes 332 on the surface can measure the ECG signal. On the other hand, it is also removed from the ear, and the ECG signal can be obtained by contacting different body parts, for example, the electrode 330 is in contact with the hand held and the electrode 332 is in contact with the torso. .

In another preferred embodiment, as shown in FIG. 8B, the ear-worn structure is implemented to obtain ECG signals when it is removed from the ear. In its actual implementation, there are many options. Among them, one One option is that the ear-worn structure can be held by the user in one hand and measured by touching the skin of the trunk part of the body. For example, the two electrodes can be implemented to contact the trunk at the same time. chest, to obtain the ECG signal of the torso, another option can be implemented as one electrode touching the holding hand and the other touching the torso to obtain the heart projection between the upper limbs and the torso, another option is to implement as Two electrodes were placed in contact with both hands to obtain cardiac projections between the two upper limbs. Therefore, the way of use can be changed according to different needs, which is very convenient.

Moreover, in order to facilitate hand holding, the ear-wearing structure can be formed to have an elongated member 316 as shown in FIG. 8B , and the electrodes are arranged on the elongated structure. It can also achieve contact with electrodes at the same time, which is more advantageous. In this case, the electrodes disposed on the elongated member can be implemented as distributed on one surface, or distributed on multiple surfaces, or implemented as continuous distribution, etc., which are all feasible ways.

In addition, the two electrodes can be further implemented to be in contact with the ear and/or near the ear when the ear-wearing structure is placed on the ear, in addition to being set at the position where the ear-wearing structure can be taken to obtain the ECG signal. Contact with the skin, such as the tragus, earlobe, wall of the concha, bottom of the concha, back of the pinna, head around the pinna (temporal lobe area), etc. The electrical signal has more functions to be used, and, as mentioned above, choosing the electrode that touches the lower half of the auricle as the reference electrode is more conducive to obtaining stable EEG signals.

Still further, it can also be implemented as having a light sensor 340, for example, as shown in FIG. Obtain blood physiological information during wearing on the ear, such as heart rate, blood oxygen concentration, etc., and then provide more diverse physiological information, and when the heart rate information can be obtained through the optical sensor, as mentioned above, Used to perform continuous detection, for example, for heart rate monitoring during exercise, and/or for patients who require long-term attention to heart activity, so that notification is received when an abnormality is detected by the light sensor, or When you feel that you have special needs, for example, when you suddenly feel an abnormal heartbeat, or when your heart feels uncomfortable, the user can immediately take off the ear-wearing structure and record real-time ECG signals by touching the torso and/or hands. It is quite helpful to correctly judge the related heart problems.

Here, it should be noted that although the above-mentioned embodiments mainly take the in-ear shell structure as an example, it is not limited thereto, and the ear-wearing structure can be implemented in various forms, for example, an ear clip structure, an ear-hook structure, Or a combined ear-wearing structure, for example, an ear shell plus an earhook structure, or an ear clip plus an ear shell structure, or the ear-wearing structure can be combined with a supporting connection structure, etc., as long as it can provide a stable contact is a viable option.

Still further, such a monaural structure can also be implemented with a port for connecting an extended electrode. For example, another electrode can be provided in addition to the original two electrodes, so that heart projections from different angles can be obtained at the same time, for example, the original two electrodes contact the chest at the same time, and then cooperate with the extended electrode to contact upper body. On the other hand, it can also be implemented as extending the electrode to replace one of the original two electrodes, and by enlarging the distance between the two electrodes, the position where the electrodes can contact can be made more variable, for example, can obtain The electrocardiogram of the respective positions of the twelve leads is also helpful to obtain more detailed cardiac information. On the other hand, it can also be implemented as extending the electrodes to obtain another electrophysiological signal. For example, the electrodes on the original unilateral earwear structure can be used to contact the ear or the head skin near the ear, and then the electrodes can be pulled out and placed on the The other ear is also in contact with the ear or the skin of the head near the ear to obtain EEG signals. So there are possibilities, no limits.

As for the embodiment of the extension electrode, various possibilities are possible. For example, it can be carried by a wearing structure, such as another ear-wearing structure, finger-wearing structure, wrist-wearing structure, neck-wearing structure, head-wearing structure, etc., or in the form of patches, straps, etc. In addition, it can also be carried by a holding structure, for example, a rod-shaped structure, which is convenient for users to operate. Therefore, there is no limitation and can be changed according to actual needs.

When the extension electrode is actually used, there are also various possibilities. For example, an ear clip structure can be extended from the original ear-mounted structure to carry the extended electrode. In this case, the extended ear-mounted structure can be clamped on the ear and the original ear-mounted structure can be used Contact the torso or upper limbs; or, a finger-worn structure can be extended to carry the extended electrode. In this case, the extended finger-worn structure can be fixed on the fingers of an upper limb, and then the original ear-worn structure can be used to contact Torso or another upper limb: Alternatively, both the original ear-wearing structure and the carrying structure of the extended electrode can be held by the hand to achieve contact, for example, to touch the holding hand, or to contact other body parts. Therefore, there are various implementation possibilities, not limited to the above description, as long as the measurement methods that can be achieved through such a structure, all belong to the scope of the present case.

In yet another aspect of the conception, the form of a headset is used as the main body to achieve multi-purpose purposes. Please refer to Fig. 9A, a multi-purpose physiological detection device includes a head-mounted structure 400, and two ear-mounted structures 410, 420, which are respectively connected to the two ends of the head-mounted structure. In addition, the physiological sensing element is arranged on the head-mounted structure. The structure and/or the ear-wearing structure, and the circuit are accommodated in the head-wearing structure and/or the ear-wearing structures, without limitation.

Among them, there are different options for the connection between the ear-mounted structure and the head-mounted structure. For example, it can be connected with a connecting wire. It can be implemented that the two are connected by a telescopic structure, and such a hard structure connection allows the head-wearing structure to obtain further fixing force from the ear-wearing structure. Therefore, no matter which method is selected, it is quite advantageous. In addition, preferably, the ear-wearing structure is implemented in the form of an ear shell, so that the ear shell and the structure of the auricle are pressed against each other, for example, the plug is placed in the ear canal, or is snapped to the inner surface of the auricle Between the physiological concave-convex structure, etc., to obtain a better fixing effect, but this is not a limitation, and it can also be implemented in other forms, and the focus is on the actual implementation situation.

Here, in particular, the head-wearing structure is constructed so that it can be combined with the head in different ways, as shown in Figures 9B-9C, the head-wearing structure can be set on the top of the head (Figure 9B), or on the forehead , or set in the hindbrain (Fig. 9C). The reason for adopting such a design is that, first of all, in terms of EEG signals, since the cerebral cortex is divided into many regions, and different cerebral cortex regions control different human activities, therefore , when the electrodes are correspondingly placed in different cerebral cortex regions, the activities of each region can be obtained respectively. The latter corresponds to the cerebral cortex of the occipital lobe, and the area above the ear corresponds to the cerebral cortex of the temporal lobe. Furthermore, in terms of eye movement, electrodes must be placed around the eyes in order to obtain electrooculogram signals. For signals and EMG signals, the forehead is the better setting position. Accordingly, it is quite convenient to just set the headwear structure at the position where you want to get the signal.

Wherein, the physiological sensing element can be implemented as at least two electrodes (not shown) to obtain electrophysiological signals on the head and/or ears. For example, one electrode can be set on the head-wearing structure and another electrode can be set on one of the ear-wearing structures. At this time, the electrode set on the ear-wearing structure can be used as a reference electrode, and the head-wearing structure When it is installed on the forehead, it can obtain EEG signals and EEG signals, and when it is installed on the top of the head and the back of the brain, it can obtain EEG signals. The symbols represent different meanings. For example, even if the electrodes are placed on the top of the head or behind the brain, if the electrodes are placed close to the top of the ears, the EEG signals from the temporal lobe will be obtained. On the other hand, if the electrodes If the electrode is placed at the top of the head, the EEG signal of the parietal lobe area will be obtained, or if the electrode is set at the back of the brain, the EEG signal of the occipital lobe area will be obtained; or, the two electrodes can also be used All electrodes are set on the head-mounted structure. In this case, when the head-mounted structure is set on the forehead, the EEG signals of the frontal lobe area and/or the EEG signals of the temporal lobe area, electroocular signals, electrodermal signals, and/or EMG, and when placed on the top and back of the head, EEG from the occipital lobe, parietal EEG, and/or temporal lobe; or, on the other ear Another electrode is set on the wearing structure. In this way, since the two ear-wearing structures are placed on both sides of the head and cooperate with the electrodes on the head-wearing structure, the left brain and the right brain can be obtained respectively. activity situation. Here, it should be noted that when used to obtain a variety of electrophysiological signals, for example, when obtaining EEG signals and electro-oculogram signals at the same time, it can be implemented with only two electrodes, and two electrodes can be obtained simultaneously through the same channel. One electrophysiological signal can also be implemented as more than two electrodes, for example, three or four, and two electrophysiological signals can be obtained from two channels, so it can be changed according to actual needs without certain restrictions .

In addition, the physiological sensing element can also be implemented as a light sensor, and is arranged on the head-mounted structure to obtain blood physiological information of the head, for example, blood can be obtained from the forehead, near the temple, and/or above the ear. Oxygen concentration, heart rate, changes in brain blood flow, etc., or it can also be set on the ear-wearing structure, and blood physiological information such as blood oxygen concentration and heart rate can also be obtained.

Moreover, further, the physiological sensing element can also be implemented to include electrodes and light sensors at the same time, and in this case, the above-mentioned various situations are all feasible. Therefore, there is no limit.

With this design, the same device can obtain almost all the physiological signals of the head, and the user can choose the position to be measured, which is quite convenient.

Here, it should be noted that since it may be necessary to place the electrodes on the top of the head, behind the head, etc. where there are hairs, in addition to using the general dry electrode form, it is also preferable to place the electrodes on the head-mounted structure It is implemented in the form of needles, for example, a single needle-shaped electrode, or an electrode with multiple needle-shaped structures to facilitate passing through the hair, wherein the electrodes with multiple needle-shaped structures can have different implementation options, such as , can be formed by soldering multiple conductive needle-like structures on the circuit board, or it can be an integrally formed conductive base and multiple conductive needle-like structures, no matter what the form is, there is no limit, as long as it can provide multiple points Contact and form an electrical connection with the physiological signal acquisition circuit, and then obtain the electrophysiological signal; moreover, it is also preferable to implement the electrode as having elasticity, for example, a spring is arranged under the electrode, or a metal Spring connectors (pogo pins) are used as electrodes, which will help to accommodate different head shape changes; or, alternatively, can also be implemented as electrode replaceable, for example, originally using non-pin electrodes, to be placed on the forehead position, When it is necessary to move to a position with hair, it is replaced with a needle electrode. In addition, the material of the electrode only needs to be a conductive material, for example, conductive metal, conductive rubber, conductive fiber, etc., so there is no certain limitation. And, preferably, when it is arranged on the forehead or behind the head, straps can be further externally connected to the head-wearing structure, for example, connected to both ends of the head-wearing structure, so as to achieve a better fixing effect.

In all the above-mentioned various implementations, for example, finger-mounted, wrist-mounted, neck-mounted, head-mounted, ear-mounted, clip-on, etc., a motion sensing element, such as an accelerometer (Accelerometer), can be added to the device. ), gravity sensor (Gsensor), gyroscope (gyroscope), magnetic sensor (Magnetic sensor), etc., to simultaneously obtain the user's body movement or movement, which can help determine whether it is due to the body's Motion or movement can cause poor signal quality. In addition, a temperature sensing element can also be added, which can be installed at a position where body temperature information can be obtained, which can help to further understand the actual physiological conditions.

Furthermore, in yet another aspect of the present invention, the function of the same physiological signal acquisition unit is extended by replacing different wearing structures.

First, in order to be easily replaced between different wearable structures, the physiological signal acquisition unit will be formed in the form of a single small housing, as shown in Figure 10A, that is, all circuits are housed in a single housing 500, when replacing, it is only necessary to remove the housing from one wearing structure and install it on another wearing structure, which simplifies the replacement steps.

Wherein, the physiological signal acquisition unit includes a physiological signal acquisition circuit, accommodated in the casing 500, has a first pair of electrical contact areas 510a, 510b on the lower surface 502 of the casing, and There are a second pair of electrical contact regions 512a, 512b on the surfaces 506 and 508. Here, since the volume has been greatly reduced, the areas of these electrical contact regions are correspondingly reduced, for example, reduced to electrical contacts form.

Furthermore, since different body parts may provide different physiological information, the physiological signal acquisition unit will also include at least one light sensor 522, as shown in the figure, which is arranged on the lower surface 502 for Obtain the user's blood physiological information, and if the electrode is also used to obtain electrophysiological signals, it can also provide results based on the relationship between the two physiological signals, such as Pulse Transit Time (PTT) ), and then information such as blood vessel hardness/elasticity can be obtained, and data related to blood pressure values can also be obtained by further estimation.

Here, the reason for adopting such a distribution of the electrical contact portions is that the possibility of use can be maximized. For example, one of the measurement options is to use the first pair of electrical contact areas to obtain electromyographic signals and electrodermal signals, etc., or to obtain electrocardiographic signals on the chest with strong electrocardiographic signals. The measurement option is that the second pair of electrical contact areas can be extended to contact more locations, and then obtain other electrophysiological signals, such as EEG signals, electroocular signals, skin electrical signals, myoelectric signals, ECG signals, etc. . Therefore, through such a design, it can adapt to different sampling requirements of various setting positions, which is quite advantageous.

Of course, what is shown in FIG. 10A is only one of the configurations in which the electrical contact area cooperates with the photosensor, and other configuration options are also possible. For example, an electrical contact can be added on the upper surface 504 as shown in FIG. 10B . Alternatively, the region 514 may only include two electrical contact regions (similar to the situation shown in FIG. 3C ), and may be disposed on the same surface as the photosensor, and/or on a different surface. Varies, no limits. In addition, other sensing elements can also be added, for example, a temperature sensing element, which is disposed on the housing where the body temperature can be obtained, which is also not limited.

When there is an electrical contact area 514 on the upper surface, another option that can be directly exposed and contacted is provided. This configuration is quite conducive to obtaining ECG signals. The contact area 514 is exposed, and it can be easily contacted by a hand, and then any one of the electrical contact areas 510a, 510b, 512a, 512b is in contact with the skin of another part of the body (direct contact or extended contact). And contact), forming the sampling circuit of the ECG signal, is also quite an advantageous implementation mode.

In this case, when it is intended to be installed on different parts of the body, such as fingers, wrists, arms, neck, chest, head, ears, it only needs to be combined with different wearing structures, such as finger-wearing structures , wrist-worn structure, arm-worn structure, neck-worn structure, head-worn structure, ear-worn structure, patches, straps, etc., can meet the needs of setting.

In addition, since the sampling positions of various parts are different, and the setting conditions are also different, therefore, further, the electrode can be set at the most appropriate sampling position through the wearable structure. In this case, preferably, the A combination structure that can be combined with the housing is provided on the wearing structure, for example, an accommodating groove, and an electrical contact portion corresponding to the electrical contact area on the housing is provided in the combination structure, so that the housing and the housing After the structure is combined, the electrical contact area on the housing can be electrically connected to the electrical contact part in the combined structure. The electrical contact area on the body is electrically connected to the electrodes on the wearable structure. In this way, the wearable structure can be directly used to achieve the positioning and fixing of the electrodes, which is quite convenient.

Here, it should be noted that when the electrical contact area on the physiological signal extraction unit is directly used to contact the skin to obtain physiological signals, it is regarded as a signal extraction electrode; on the other hand, when it is When it is used to make contact with the electrical contact part in the wearable structure to achieve the electrical connection between the electrode and the circuit on the wearable structure, it is regarded as an electrical contact, which depends entirely on the actual implementation situation, without limitation, and therefore, The same electrical contact area on the casing may have different functions when matched with different wearing structures.

The following is a detailed description of how to install the physiological signal acquisition unit on various parts of the body, what kind of physiological signals it can be used for, and its application range.

First, in the simplest case, the physiological signal acquisition unit is set on a finger of the user through a finger-worn structure. Here, the set position can be the fingertip, or where the proximal or middle phalanx is located. There are no restrictions on the knuckles, and there is no restriction on which finger, only a corresponding suitable finger-wearing structure can be provided. Set on the fingertips, if a ring-shaped finger-worn structure is used, it can be set at the knuckle position; if a finger-clip-shaped finger-worn structure is used, as long as the shape is suitable, it can be set on the fingertip or on the On the knuckles, the form of implementation can be changed according to actual needs. Furthermore, it can also be implemented as a fixed structure formed of sticky and soft materials, such as patch, patch, Velcro, etc., which are suitable for setting on any finger. Festival.

In addition, in terms of size, if it is to be suitable for placement on the fingers, it is preferably minimized, for example, the dimensions of the housing are optimally implemented with a length of less than 30 mm and a width of less than 25 mm, and The thickness is less than 10 mm, so even if it is set on the finger, it will not feel awkward and burdensome.

When the physiological signal acquisition unit is set on the finger, the most suitable physiological signal acquisition is to use the optical sensor to obtain blood physiological information from the finger, such as blood oxygen concentration, heart rate, blood flow, etc. Generally the most well-known blood oxygen concentration takes place.

Here, it should be noted that, as mentioned above, the common blood oxygen concentration sensors on the market generally adopt two measurement methods, penetrating and reflective. Among them, the penetrating, as shown in Figure 2A, uses the The light-emitting element and the light-receiving element are placed on both sides of the finger separately, and the measurement is carried out by allowing the light to penetrate the blood vessel. Generally speaking, the signal obtained by this method is relatively stable. On the other hand, the reflection type, as shown in the figure As shown in 2B, the light-emitting element and the light-receiving element are disposed on the same side of the finger, and this method has the advantages of a relatively simple structure and relatively low power consumption. Therefore, both methods have their own advantages and can be used.

Therefore, when the form of a single shell is adopted, it is preferable to use a reflective method for measurement, that is, the light emitting element and the light receiving element are arranged on the same side of the finger. On the other hand, if the wearing structure has physiological When sensing elements, for example, the light-emitting element is set on the housing, and when the light-receiving element is extended to the wearable structure, it can be measured in a penetrating way. Therefore, no matter where it is set on the finger, it can be required There is no limit to choose to use the penetration method or the reflection method to measure according to the difference.

Here, it should be noted that the finger-wearing structure used, like the above, can be in any form that can be fixed on the finger, for example, a ring structure, a finger loop structure, a finger clip structure, a surrounding structure, etc., without limit. On the other hand, there are various options for the material. For example, elastic materials can be used, such as silicone, rubber, etc.; or flexible materials can be used to fix them by winding, such as Velcro felt; Alternatively, a viscous substance can be further added to be fixed by means of adhesion; alternatively, a hard material conforming to the ergonomic structure of the finger can also be used, for example, plastic formed into a clip shape, or plastic formed into a ring form , metal, etc.; or, different materials can be used in combination, for example, a hard material can be coated outside an elastic material; it can even be implemented in a disposable form. Therefore, all possibilities are possible without limitation.

As for the combination of the shell and the finger-worn structure, there are various options, for example, it can be implemented in various feasible ways such as embedding, engagement, magnetic attraction, adhesion, binding, etc. There is no limit, as long as the Combine and fix.

For example, in one embodiment, the finger-wearing structure is implemented as a fingertip cover made of silicone material (similar to the structure shown in FIG. 11A ), and the housing can be directly embedded in the fingertip cover very simply. It is not only convenient to make, but also easy to fix and locate, and it is also very comfortable to use; in another embodiment, the finger-wearing structure can also be made of a recoverable elastic material, and the structure can be opened through the design of the structure. 11B-11C, the housing can be plugged into the elastic finger-wearing structure 600b; in another embodiment, the finger-wearing structure is implemented as an adhesive non-woven fabric , can be used to surround the knuckles, and can also be used to stick to the fingertips. In another embodiment, the finger-wearing structure is implemented as Velcro felt, which can be freely adjusted and adapted to different finger sizes; in another embodiment, such as As shown in Figures 11D-11E, the finger-wearing structure is implemented as a ring-shaped finger-wearing structure 600c, and the combination of the shell and the ring can be in various ways, for example, through snap-fitting, plugging, magnetic attraction, etc. ; In yet another embodiment, the finger-worn structure is implemented to use elastic material inside, while the outside is coated with hard material, such as a plastic shell, so that the elastic material can be used to conform to the curve of the finger to stabilize the physiological feeling It can also provide a suitable and beautiful appearance while setting up the measuring element, and even set the exposed electrode through the hard material shell, and connect it to one of the electrical contact areas on the physiological signal acquisition unit, so that Come, you will be able to measure the ECG.

Such an arrangement is especially suitable for detecting sleep physiological state information, such as breathing conditions and sleep quality, during sleep. This is because, when such a design is adopted, not only is the volume small, but the structure set on the finger becomes quite simple, it is not easy to fall off, and it will not cause hindrance during sleep at all, but it can obtain the blood oxygen concentration very reliably. And information such as heart rate, where blood oxygen concentration can be used to understand the breathing situation during sleep to provide information about sleep disordered breathing (Sleep Disordered Breathing, SDB), such as Obstructive Sleep Apnea (OSA), heart rate can be used To understand other physiological information during sleep, such as heart activity, and other physiological information derived therefrom, such as the time to fall asleep, and further, if the housing is also provided with a motion sensing element, then It can also detect the movement of hands and body, etc., and these are closely related to the quality of sleep, so it is quite advantageous.

Furthermore, if it is used during sleep, in order to allow the user to use it freely, the surrounding range of the finger-wearing structure can also be extended to a part of the palm, for example, as shown in Figure 11F, the surrounding finger-wearing structure 600d adds a part around the palm below the thumb. In this way, through a larger area of fixation, the user will feel more stable and will not affect sleep. Of course, the actual implementation form of the finger-wearing structure is shown in Figure 11F. It is only used as an example, not as a limitation, as long as the structure that surrounds a part of the palm at the same time is within the scope of this case, there is no limitation.

On the other hand, in addition to obtaining blood physiological information by using the optical sensor, electrophysiological signals can also be obtained through electrodes. As mentioned above, due to the small volume of the housing, the contact area of the electrical contact area is small, and the distance between the two electrical contact areas is short, in addition to being used to directly obtain electromyographic signals and skin electrical signals, when you want to obtain other electrical signals Physiological signals, or when the acquisition position of electromyographic signals and/or electrodermal signals cannot be directly achieved by the shell, the contact between the electrodes and the skin can be achieved by further changing the finger-worn structure.

In practice, the finger-worn structure is implemented with a coupling structure for receiving the housing, and has electrodes located on the accessible surface and electrically connected to electrical contacts located within the coupling structure, thus, through the housing Combined with the combination structure, the original electrical contact area on the housing can be extended to the electrodes on the finger-worn structure. Here, it should be noted that, depending on the actual measured physiological signals and the different positions to be set, the extension of the electrodes can be implemented as extending only a single electrode, or both electrodes can be extended outwards. way of implementation.

Wherein, when used to obtain electrodermal signals or electromyographic signals, only one electrode can be extended to lengthen the distance between the electrodes, or both electrodes can be extended through the finger-worn structure to be arranged at different positions.

In addition, when used to obtain ECG signals, since one electrode must contact other body parts other than the limb where the finger wearing the housing is located, at least one electrode must be extended through the finger-worn structure. In practice, There are many different options. For example, in one embodiment, one electrical contact area on the housing can be made to contact a finger, and the other electrical contact area can be extended to the exposed surface through the finger-worn structure to contact other body parts; in another embodiment In the present invention, it can also be implemented that the two electrical contact areas both extend through the finger-worn structure, so as to respectively contact fingers and other body parts. Therefore, all possibilities are possible without limitation.

Therefore, by simply changing the finger-worn structure, the same casing can perform different physiological detection behaviors and obtain different physiological signals, which is quite advantageous.

Furthermore, the housing can also be implemented in combination with a head-wearing structure, as shown in FIG. 12A , so as to be disposed on the user's head. As we all know, the head can obtain many physiological signals, for example, the electrodes can be used to obtain EEG signals, electro-oculogram signals, skin galvanic signals, myoelectric signals, etc., and changes in brain blood flow can be obtained by using optical sensors. Blood oxygen concentration, heart rate, etc., and among them, EEG signals, electro-ocular signals, and changes in brain blood flow are physiological information that can only be obtained from the head, so they are very important physiological monitoring positions.

In this case, because the position of the electrodes for obtaining EEG signals has certain restrictions, for example, the electrodes are generally installed according to the international 10-20 EEG configuration system (international 10-20 system). The electrodes need to be arranged around the eyes, therefore, it is suitable to use the above-mentioned electrode extension design to arrange the electrodes to the required positions through the head-wearing structure.

In practice, similarly, as shown in FIG. 12B , the head-mounted structure 700 is implemented as having a coupling structure 710 for receiving the shell, and in particular, on the coupling structure, there will be corresponding electrical The electrical contact parts of the contact area 510b and the electrical contact area 512b are combined to achieve electrical contact, and then electrically connected to the extension electrodes 740 provided on the head-mounted structure through the connecting wires arranged along the head-mounted structure , in this way, even if the housing according to the present case is very small in size, the EEG signals can be obtained very simply.

Moreover, as long as the form of the head-wearing structure is changed, for example, the type of the head-wearing is changed, the electrodes can reach any head area, and the EEG signals of the corresponding cerebral cortex area can be obtained, for example, when placed on the forehead When it is set on the top of the head, it can get the EEG signal of the parietal lobe area. When it is set on both sides of the head and near the top of the ear, it can get the EEG signal of the temporal lobe area. signal, and when placed on the back of the head, it can obtain EEG signals in the occipital lobe area. As we know, different cerebral cortical regions are in charge of different functions of the human body, therefore, it is meaningful to monitor each cerebral cortical region.

As for the form of the headwear structure, there are different choices depending on the position where the signal is to be obtained. For example, if you want to set it on the forehead, you can simply use a patch, cloth, or glue to reduce the burden, or you can In the form of straps or a head frame with clamping force, if you want to set it on the top of your head, you can use a head frame, hat, etc. If you want to set it behind the head, you can use a strap, hat, head frame, etc. ; In addition, if you want to obtain the eye signal, you can set it on the forehead, or extend down to around the eyes. Therefore, there is no limit and can be changed according to actual needs.

Among them, a special form of head-mounted structure is the glasses structure. Generally, when the glasses are worn on the head, they will touch the bridge of the nose and the top of the ears, and in some cases, they will also touch the surroundings of the eyes. Therefore, this configuration is very suitable for obtaining oculoelectric signals. EEG signals in the frontal lobe area, and EEG signals in the temporal lobe area. Moreover, since the volume of the housing according to the present invention can also be implemented to be very small, it is also quite suitable for combining with the structure of eyeglasses.

Here, it should be noted that, depending on the actual measured physiological signal and the position to be set, the extension of the electrical contact area can be implemented as a single extension, or both of the electrical contact areas can be implemented outwardly. For example, when the head-mounted structure is arranged on the forehead, or when the head-mounted structure is implemented as a glasses structure, one electrical contact area on the shell can be directly used, and only one electrical contact area is extended. Therefore, there is no limit .

And this setting is also very suitable for use during sleep. For example, the main basis for judging sleep stages is EEG signals, such as rapid eye movement (REM, Rapid Eye Movement), deep sleep, light sleep, awake etc. In addition, EMG and EoG signals will also be used to determine whether it is in the rapid eye movement period, and these are physiological information commonly used to judge sleep quality. Furthermore, the blood oxygen concentration obtained by the light sensor can be used To obtain the breathing situation during sleep, for example, when sleep apnea occurs, it is usually accompanied by a drop in blood oxygen concentration, so it can be judged whether sleep apnea occurs by observing the blood oxygen concentration. In addition, the obtained heart rate can be understood The physiological state during sleep, for example, the state of the autonomic nerve, the situation of the heart activity, whether there is arrhythmia, etc., can also be used to determine the time of falling asleep (sleeponset), etc. In addition, if the housing is also provided with a motion sensing element , it can also detect the user’s movements such as turning over. Therefore, almost all the physiological signals obtained by general sleep examinations have been included, and it can be completed only with a small and compact shell and a head-mounted structure, without complicated The wiring is quite advantageous.

Still further, the housing can also be combined with a neck wearing structure 800 . As shown in Figures 13A-13B, through the neck wearing structure, the housing can be placed in front of a user's torso, and in the case of being placed in front of the torso, it is very suitable for obtaining ECG signals, and because The housing is small in size, and the distance between the two electrical contact areas is very short. Therefore, the electrical contact area can be extended by combining the structure of the neck wear structure with the housing. For example, as shown in FIG. 13B, only Extend one electrical contact area to electrode 810, or, as shown in FIG. Next, as long as the user presses the combination of the shell and the combination structure located in front of the drive, the user can easily obtain the ECG signal.

In addition, the optical sensor in the housing can also obtain blood physiological information from the torso or from the hand through hand contact, such as blood oxygen concentration, pulse wave signal, heart rate, etc., and can also obtain ECG signals at the same time And the pulse wave signal, as mentioned above, the pulse wave transit time can be obtained to obtain the information such as the hardness/elasticity of the blood vessel, and then estimate the data related to the blood pressure value.

In addition, the housing can also be implemented to be combined with an ear-wearing structure. Due to the very small volume of the shell, when it is placed on the ear, it is not much different from the volume of the current common earphones on the market, not only does not cause a burden, but also does not appear obtrusive.

On the ear and/or near the ear, the blood oxygen concentration, pulse wave signal, heart rate, etc. can be obtained through the optical sensor, and the EEG signal, EMG signal, skin galvanic signal, ECG signal, etc. can be obtained through the electrode. Various options. Among them, the setting of the light sensor only needs to be in contact with the ear or the skin near the ear, and the EEG signal, electromyography signal, skin electrical signal, etc. can be obtained by contacting the ear and/or the skin near the ear with two electrodes. , as for the ECG signal, it is preferably implemented with one electrode in contact with the ear or the skin near the ear, and the other electrode extending to the exposed surface for contact by an upper limb.

As for the form of the earwear structure, there are also various possibilities. Whether it is the form of the ear shell, the form of the earhook, or the form of the ear clip, it is all feasible, and the materials used can also vary according to different forms. Correspondingly, the arrangement of electrodes and photosensors will also be different. For example, when it is implemented in the form of an ear shell, it can be implemented to cover the shell with an elastic material, such as silicone, so that it can adapt to the depressions and protrusions on the inner surface of the auricle. At this time, the electrodes can directly It is exposed through the hole in the covering material, and the above-mentioned extended form can also be used to achieve contact with the skin; when it is implemented in the form of ear hooks, there will be a pendant hanging above the auricle, so it increases It is possible to contact the back of the auricle and/or the head near the ear. At this time, the electrodes can be extended to the pendant by extension. As for the installation position of the shell, it can be set in front of the auricle or on the ear. The position behind the pinna is optional; when it is implemented as an ear clip, the electrodes can be extended to the inner surface of the ear clip to contact the skin of the part where the ear is clipped, such as the earlobe, the edge of the pinna, etc. Extend the electrodes to the exposed surface of the ear clip for upper extremity contact. As for the light sensor, no matter what kind of ear-worn structure is used, it only needs to ensure that it will be exposed, contactable and fixed on the skin. Therefore, it is a feasible method without limitation.

Still further, the housing can also be combined with a wrist-worn structure 900, as shown in Figures 14A-14B. In the vicinity of the wrist, blood physiological signals such as pulse wave signals, heart rate, and blood oxygen concentration can be obtained through optical sensors, and electrophysiological signals such as myoelectric signals, skin galvanic signals, and electrocardiographic signals can be obtained through electrodes. The acquisition of the signal and the electrodermal signal requires two electrodes to contact the same part of the skin at the same time. In addition, the acquisition of the ECG signal can be implemented as one electrode touching the skin near the wrist, and the other electrode extends to the exposed surface for other Body part contact, eg, another upper body, torso, etc.

Here, due to the small volume of the casing, the shape of the wrist-worn structure will become very free, which can be in the form of a bracelet, a watch, or a belt. In this way, the user can Choose your desired wrist-worn structure based on your usage habits.

The arrangement of electrodes and photosensors is similar to the above. Among them, the light sensor needs to be exposed and set at a position that can be touched and fixed on the wrist. As for the electrode, it can be implemented by directly exposing the electrode 514 on the shell to achieve contact, as shown in Figure 14A, and can also be used on the wrist-worn structure The extended electrodes 910, as shown in Figure 14B, are not limited.

Here, it should be noted that the above-mentioned wearing structure is only for illustration, not as a limitation, and the wearing structure that can be matched with the housing according to the present utility model is not limited, as long as it can be combined with and attached to the housing Wearable structures on the surface of the human body, such as arm-worn structures, chest straps, leggings, patches, etc., all belong to the application scope of this project, without limitation.

In summary, by redefining the housing size of the physiological signal acquisition unit and the configuration of the optical sensor and electrical contact area on it, the same physiological signal acquisition unit can be used in a variety of wearable structures, so it can It is installed on various body parts that can obtain various physiological signals, such as the head, ears, torso, arms, wrists, fingers, etc., and the physiological signals that can be obtained at these positions almost cover the needs of general physiological monitoring.

Moreover, further, if a motion sensing element is arranged in the casing, the movement of the body can also be obtained, and/or a temperature sensing element can be added to obtain body temperature information, which will be more advantageous.

Furthermore, when the above-mentioned device is applied to the detection during sleep, especially when it is implemented as a finger-wearing form, in addition to the above-mentioned situation where the wearing structure and the housing are detachable, it can also be implemented as an integrally formed finger-wearing structure 600e, for example , as shown in Figure 15, the housing clamped on the fingertips, or directly formed as a finger-worn structure fixed by a ring, are all feasible ways, there is no limit, as long as it can be fixed on the finger.

During sleep, there are several physiological signals that can be measured on the fingers and reflect the physiological state of sleep. For example, the blood oxygen concentration can be used to know whether there is hypopnea, such as shallow breathing, apnea, etc. It is because when there is hypopnea, the amount of oxygen in the blood will drop. Therefore, the change of breathing during sleep can be known by observing the change of blood oxygen concentration; moreover, the heart rate can be used to assist in observing the physiological state during sleep, such as , the state of the autonomic nerve, the condition of the heart activity, whether there is arrhythmia, etc., can also be used to determine the time to fall asleep (sleep onset); further, if a motion sensing element is added, such as an accelerometer, it can provide body movement Information. Therefore, even if it is only a small-sized device worn on the finger, a considerable amount of information about the physiological state of sleep can be obtained by combining the above-mentioned information, for example, sleep quality, which is especially suitable for understanding whether there is sleep disordered breathing (Sleep Disordered Breathing (SDB), for example, Obstructive Sleep Apnea (OSA).

On the other hand, if a program that helps to fall asleep and/or relieve stress can be provided at the same time after knowing one's own sleep condition, it will be a more complete solution for the user.

In recent years, more and more studies have shown that the human body can affect the body's operating system through self-consciousness regulation to achieve the effect of improving physical and mental health, for example, triggering a relaxation response (relaxation response) in the body. The so-called relaxation response can be said to be a physical response complementary to the fight-or-flight response. Generally speaking, the relaxation response occurs when the body no longer perceives danger. At this time, self-discipline The activity of sympathetic nerves in the nervous system will decrease, and this response can be induced in the body through meditation, breathing training, biofeedback, progressive muscle relaxation, yoga, etc. It can be used to treat symptoms such as stress and anxiety.

Among them, physiological feedback is a learning process in which the human body learns how to change physiological activities for the purpose of improving health and performance. In this program, the physiological activities in the human body can be changed through consciousness, such as thinking, emotion, and behavior. , for example, brain waves, heart rate, respiration, muscle activity or skin temperature, etc., will be monitored by the instrument, and the information will be fed back to the subject quickly and accurately. Since this information is related to the desired physiological change, therefore, After the subject obtains the information, he can conduct self-consciousness regulation based on it, so as to strengthen the required physiological response and/or improve his own physiological state, etc.

And through the configuration of the electrodes and/or other physiological sensing elements in the physiological detection device mentioned above, the physiological signals that can be obtained, such as brain electrical signals, myoelectric signals, skin electrical signals, heart rate, blood flow, skin temperature, etc. Physiological signals often used in physiological feedback programs.

Among them, when the α wave is dominant in the brain wave, it means that the human body is in a relaxed and awake state; when the β wave is dominant, it means that the human body is in a awake and tense state; and when the θ wave is dominant, it means that the human body is in a state of relaxation and interruption of consciousness. Therefore, the physiological and conscious state of the human body can be known by observing the changes in the brain wave; the EMG signal represents the tension of the human muscles, and the muscle tension is also related to the activity of the autonomic nerves, so it can be used to know the muscle tension. The degree of tension; electrical skin activity is related to the activity of sweat glands, and the secretion of sweat glands is only affected by sympathetic nerves, and when the activity of sympathetic nerves increases, the activity of sweat glands increases, so the increase in activity of sympathetic nerves can be known by measuring electrical skin activity As we all know, a decrease in sympathetic nerve activity means an increase in parasympathetic nerve activity, that is, the human body is in a more relaxed state; the heart rate is regulated by both the sympathetic and parasympathetic nerves, and when the sympathetic nerve activity increases, The heart rate becomes faster, and when the activity of the parasympathetic nerve increases, the heart rate slows down, so the activity of the two can be known by observing the heart rate sequence; in addition, because the blood vessels sent to the skin of the extremities are only affected by the sympathetic nerve, and When the sympathetic nerve activity decreases, the vasoconstriction decreases, the diameter of the vessel becomes larger, the blood flow increases, and the skin surface temperature rises. Therefore, the increase or decrease of the activity of the sympathetic nerve relative to the parasympathetic nerve can also be inferred by measuring the skin temperature at the extremities, such as , the temperature is measured by the temperature sensing element.

As we all know, sympathetic nerves and parasympathetic nerves are the autonomic nervous system of the human body. Therefore, by obtaining these physiological information, we can know the physiological information related to the autonomic nerves of the human body. Therefore, these physiological information, whether it is electrophysiological information or Blood physiological information, or body temperature information, are suitable for use in physiological feedback programs. For example, physiological feedback can be performed before going to bed to achieve a physiological state that is conducive to falling asleep. For example, physiological feedback can be used to increase the concentration of brain waves. The proportion of α waves is used to induce sleep. In addition, physiological feedback can also be performed when you are free. For example, increasing the activity of parasympathetic nerves through physiological feedback will help relieve mental stress.

In this case, the device according to the present utility model only needs to further cooperate with an information providing unit to provide the relevant obtained physiological signals to the user through a notification message, so that the user can know the physiological changes in real time, This then leads to the settings required to execute the Physiological Feedback program.

For example, an information providing unit can be directly provided on the physiological detection device to provide information through various notification methods that are visual, auditory, and/or tactile. Perceivable methods, such as sound, voice and other auditory perceptible methods, and/or tactile perceptible methods such as vibration and temperature changes, can be achieved by setting heating elements, vibrating elements, sound emitting elements, display elements, etc., and there are various possibilities ,no limit.

Moreover, based on the multi-purpose characteristics of the device of the present invention, the user can also choose the physiological signal as the basis for physiological feedback based on different feedback purposes or differences in usage habits. For example, as long as the finger-worn structure is selected , body temperature information, blood physiological information, and/or skin electrical information can be obtained from the finger, and the physiological feedback of relaxation can be simply performed, which is quite convenient.

Furthermore, when using the wearable physiological detection device according to the utility model, it is only necessary to simply arrange the wearing structure, for example, put on a ring, glasses, earphones, a wristband, etc., which is equivalent to completing the physiological monitoring. The setting of the sensing element, and then, only need to start the physiological detection and obtain the real-time physiological information through the information providing unit, then the physiological feedback can be performed, which is quite convenient, and because of such a simple and convenient setting, there is almost no need to use it. Restrictions on time and place, for example, during commuting, before going to bed, etc. are the time and place where physiological feedback can be performed, which is quite helpful to improve the user's willingness to use.

In contrast, the traditional physiological detection devices used in physiological feedback often present complex wiring situations. For example, there is usually a machine set on the table next to the user, and the wiring from the machine to the user is usually done. On the body, for example, if EEG signal detection is performed, multiple wires will be connected to the user's head. If electrodermal signal is measured, the usual method is to have two wires connected to the user's two fingers respectively. If the body temperature is measured, it also needs to be wired to the location where the body temperature is to be obtained. In this case, the user is tied to the desk, which not only limits the place of use, but also limits the time of use, which is quite inconvenient.

Of course, in addition to being used for physiological feedback, the information providing unit can also be used to provide other notifications and instructions related to the user during other wearable periods. For example, when the detected physiological signal meets the default condition, For example, rapid heartbeat, arrhythmia, low blood oxygen concentration, etc., will remind the user through various methods such as sound, vibration, and flashing lights, so there is no limit.

In addition, the information providing unit can also be implemented as an external device, such as a smart phone, a smart watch, a tablet, a computer, etc. In this case, the device according to the present invention only needs to include a wireless transmission module, such as , bluetooth module, can achieve wireless communication with the external device, and provide user information in real time during physiological feedback, for example, using real-time wireless transmission with a smart phone, for example, by executing an application on the mobile phone Program (APP) to communicate with the physiological detection device worn on the body. The above-mentioned various perceptible methods, whether visual, auditory, or tactile, can be achieved by using mobile phones, which not only reduces the burden on the hands, but also Since various portable electronic devices such as smart phones and tablets have been fully integrated into the daily life of ordinary users, it is also quite easy to operate without additional learning.

In addition, the wireless communication can also be used for pure information transmission besides being used for physiological feedback period, for example, the physiological signals captured, and detection results, etc., in this case, it can be implemented as real-time wireless transmission, or The implementation is carried out after the physiological monitoring is over, and there is no limit. Therefore, a memory can also be set in the housing to store the obtained physiological signals and download them to an external device after the monitoring. Of course, the memory can also be used as a wireless transmission There is no limit to the previous buffer memory.

Here, it should be noted that this wireless communication and memory can be implemented in the devices in all the aforementioned embodiments of this case, that is, any device mentioned so far in this paper can be further configured with a wireless transmission module, and can communicate with a Wireless communication between external devices, for example, can be used to transmit the measured physiological information to the external device, or the external device can control and set the device on the wearer through the wireless communication, and/or Or configure a memory, there is no limit, and such a configuration further improves the convenience and performance of the wearable form, which is quite advantageous.

In summary, the utility model provides the concept of a multi-purpose physiological detection device. By using different wearing structures, the same device can be conveniently and simply installed on different body parts to obtain different physiological The signal is not only cost-effective, but also achieves the purpose of allowing users to change the way of use according to different needs, so as to obtain the most suitable physiological signal.
