In the concept of the present invention, in order to achieve the purpose of multi-purpose, the means adopted is to concentrate the circuits, components, physiological sensing components, etc. required for physiological signal detection as much as possible on the same casing, so that Can be easily changed by simply changing the wearing structure Change the setting position or setting method of the casing to obtain different physiological signals.

According to this, according to the multi-purpose physiological detection device of the present invention, there will be a casing as the main body, which is mainly used for accommodating circuits / components and providing physiological sensing components. As shown in FIG. 1, the multi-purpose physiological detection device according to the present invention includes a physiological signal acquisition circuit 110 and is electrically connected to a physiological sensing element, such as an electrode, and / or a light sensor to obtain a physiological signal. Here, it should be noted that the physiological signal acquisition circuit will include all circuits and components necessary to obtain physiological signals, such as processors, analog signal processors, analog digital converters, filters, and memories. As batteries, batteries, etc. are well known to those with ordinary knowledge in the field, they will not be repeated here. In addition, if there is a need for wireless transmission, for example, to transmit the acquired physiological signals to external devices, It includes a wireless transmission module, or the memory can 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 and are not limited.

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

Here, it needs to be explained that generally, when capturing electrophysiological signals, a signal acquisition electrode and a ground electrode are usually provided. Among them, the signal acquisition electrode is to obtain an electrophysiological signal, and the role of the ground electrode is to remove the background. Noise, and all the electrodes described in this article belong to the signal acquisition electrode, but in order to avoid the word is too long, in the following description, "electrode" stands for "signal acquisition electrode", as for the ground The electrode settings are generally set selectively according to actual needs, so they are omitted here, and to simplify the description, when the electrodes are used to obtain specific types of electrophysiological signals, Will be described directly as this type of electricity Electrodes for physiological signals, such as ECG electrodes, EEG electrodes, ophthalmic electrodes, myoelectric electrodes, skin electrodes, etc.

In addition, the electrodes described herein are generally well-known conductive materials that can sense the self-generating potential difference of the human body, such as metals, conductive fibers, conductive rubber, conductive silicone, etc., so in the following description, only the The electrode installation position, installation method, and shape will be described.

In addition, the light sensor refers to a sensor having both a light emitting element and a light receiving element. It transmits light into the human tissue through the light emitting element, and the light penetrates the blood in the blood vessel or passes through the blood. After reflection, it is received by the light-receiving element, and then the blood physiological information is obtained by obtaining the volume change caused by the light.

In general, when the blood physiological information is obtained through penetration, as shown in FIG. 2A, the light emitting element 122a and the light receiving element 122b are respectively disposed on the measurement site, for example, both sides of a finger, and when implemented In order to obtain blood physiological information through reflection, as shown in FIG. 2B, the light emitting element 122a and the light receiving element 122b will be set on the measurement site, for example, on the same side as a finger, and when the setting position is between the two Between these positions, depending on the actual situation, it may be a penetration method and / or a reflection method.

In addition, even in the form of a replaceable wearing structure, the physiological sensing element can be set on the wearing structure without limitation, and the benefit brought by this can be achieved by replacing the wearing structure, for example, Various options such as replacing the type of the physiological sensing element, increasing or decreasing the number of the physiological sensing element, and changing the setting position of the physiological sensing element are also quite advantageous. The detailed implementation will be described later.

First of all, in the first aspect of the case, a multi-purpose design with fingers as the main choice was selected.

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

As shown in FIGS. 3A-3B, a finger-mounted structure 200 carries a shell 100, and the shell 100 The body is provided with a physiological sensing element, such as an electrode and / or a light sensor. When implemented as an electrode, both electrodes 120 can be disposed on a surface of the housing that will contact with a finger (see FIG. 3A). (Shown) to obtain skin signals, myoelectric signals, etc .; or as shown in FIG. 3B, an electrode 120 may be disposed on a surface that will contact a finger, and then disposed on a surface that does not contact the finger. The other electrode 120 obtains the ECG signal by contacting different parts of the body respectively. In addition, when implemented as a light sensor, the light sensor can be disposed on the surface of the housing facing the finger. And ensure that the light used for sensing can enter the finger, so that during the wearing process, the blood physiological information is obtained from the finger through the light sensor, or the light sensor can be set on the outer surface of the housing , Through contact with other body parts, for example, the other hand, to obtain blood physiological information; furthermore, it can also be implemented as an electrode and a light sensor at the same time, in this case, the configuration of the electrode and the light sensor is According to actual needs There are various combinations without any restrictions.

Therefore, it is convenient for the user to perform physiological detection by simply wearing the ring, and since the use of the ring form hardly interferes with daily life and is not obtrusive, it is very suitable for use in daily life.

Here, the form of the finger-wearing structure is not limited, as long as the housing can be maintained on the finger and the setting of the physiological sensing element can be achieved at the same time, for example, it can be a ring structure, a C-type structure, etc., for example, Ring structure, finger clip structure, finger sleeve structure, strap structure, etc. are all available. In addition, the material can also have different choices. For example, it can be implemented as a rigid material, such as plastic, metal, etc., or it can be implemented. Soft materials and / or elastic materials, such as silicone, rubber, cloth, etc., are all feasible ways, that is, the above-mentioned various finger-wearing structures can use hard materials within the achievable range, or There are no restrictions on soft / elastic materials or mixed materials.

Next, as long as the housing is implemented to be detachable from the finger-wearing structure, it can be achieved for multiple purposes. One option is to place it on another part of the body through another wearing structure. For example, it can be placed on the torso through a patch structure or a neck wearing structure. In this case, The electrodes originally arranged on the same surface can contact the trunk at the same time to obtain ECG signals, myoelectric signals, and / or skin signals, or the electrodes disposed on the opposite surface can touch the hand and the trunk respectively by pressing with one hand. The ECG signal can be obtained. As for the light sensor, the blood physiological information can be obtained from the trunk or the contacting hand; or it can be set on the wrist through the wrist wear structure, whether it is an electrode or a light sensor. , All kinds of physiological signals / information can be obtained smoothly, for example, the electrodes on the opposite side can obtain the ECG signals by contacting the wrist and another part of the body, such as the other hand or the trunk, and set them on the same The electrodes on the surface can obtain myoelectric signals, skin signals, etc. from the wrist, and since the original implementation is finger-type, the volume will be very small when the casing is placed on the wrist, similar to the bracelet It feels like the burden is quite small.

Another option is to change the size of the finger-wear structure to accommodate different finger sizes or fingers of different users, especially when the finger-wear structure is implemented in the form of a ring, such as a ring. The structure has restrictions on the adaptation of different fingers. Therefore, if the ring bodies of different sizes can be replaced, a single device can be easily adapted to fingers of different sizes. In this way, in addition to the finger that the same user can freely choose to set In addition, different users can share the same device, which is quite cost-effective.

In actual implementation, one of the embodiments is that the replaceable finger-wearing structure is implemented as a simple structure without a physiological sensing element. In this case, the electrodes, light sensors, The physiological signal acquisition circuit and the like are all arranged in a housing that can be combined with the finger structure, that is, the housing and the finger structure are only a simple mechanical combination, in which the light sensor can be set When the housing is combined with the finger-wearing structure, the direction facing the finger or the direction facing outward, in addition, the settings of the electrodes are different depending on the obtained physiological signals. For example, if used to obtain ECG signals, One electrode needs to be in contact with the finger, and the other electrode is exposed to allow contact with other parts of the body. If used to obtain myo-electrical signals and / or skin signals, two electrodes need to be on the same side, for example, touching the fingers at the same time, or at the same time Exposed and touching other parts of the body.

Moreover, another implementation option is that the replaceable finger-wear structure is implemented to have a physiological Sensing elements, such as light sensors and / or electrodes, in this case, in addition to the mechanical coupling between the wearing structure and the housing, an electrical connection must also be made to enable physiological sensing on the wearing structure. The component can be electrically connected to a physiological signal acquisition circuit located in the casing. Here, it should be noted that the physiological sensing element on the finger-wearing structure can be a light sensor, or a single electrode to match the electrode on the housing, or it can be two electrodes. Designs vary and there are no restrictions. As mentioned above, the light sensor includes a light-emitting element and a light-receiving element. Therefore, when it is set on the finger-wearing structure, it can be set to use the penetration method or the reflection method to obtain blood physiological signals. feasible.

In addition, in a special embodiment, another special embodiment can be generated by changing the material of the finger-wearing structure. When the finger structure is implemented as a metal material, as shown in FIG. 3C, for example, a common stainless steel ring can be made by contacting the finger structure with one of the electrodes on the original housing, thereby making the metal finger The wearing structure becomes an 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 increased accordingly, which is quite convenient. In addition, another electrode is located on the exposed surface of the case. Therefore, such a setting would be particularly suitable for capturing ECG signals. The advantage brought by this is that the structure of the finger-wearing structure becomes quite simple, without the need to separately provide electrical connection lines and electrodes, the production process can be simplified to the greatest extent, and the production cost can be reduced.

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

Furthermore, when the ECG signal measurement is only required, the conductive finger-attachment structure and the shell cannot be separated directly, and the shell is fixed to the finger-knot. Structurally, this will be more cost-effective.

In the idea of the other aspect of the present case, the multi-purpose setting selection based on the head is selected.

As is well known, the head can also obtain considerable physiological information, such as brain electrical signals, eye movement signals, myoelectric signals, and cerebral blood flow (HEG, hemoencephalography). Therefore, it is particularly suitable for obtaining sleep physiology during sleep. Information such as state or sleep quality, or used during physiological feedback and neurophysiological feedback. Under this premise, if you can provide the option of setting in other body positions to obtain other physiological signals, it is naturally another item for users. profitable.

Accordingly, in this embodiment, as shown in FIGS. 4A-4B, the physiological sensing element is disposed on the lower surface 101 of the housing. For example, FIG. 4A shows a case where two electrodes 120 are provided, and FIG. 4B shows a setting light. In the case of the sensor 122, in this way, the setup method shown in FIG. 5 can be used to obtain physiological signals from the head. For example, FIG. 4A can obtain brain signals, eye movement signals, and skin signals. , Myoelectric signals, etc., and FIG. 4B can obtain brain blood flow, blood oxygen concentration, etc., and in this case, as mentioned above, the light sensor will use the reflection method to obtain blood physiological information. Furthermore, it can also be implemented by providing electrodes and light sensors at the same time to obtain more physiological signals. For example, it can be implemented by placing electrodes and light sensors on the same plane, or on different planes. There are no restrictions.

Here, the housing provided on the head is provided by a headgear structure. For example, straps, helmets, hats, glasses, patches, adhesives, etc. are all optional forms. In particular, the headgear structure can also be implemented to have an electrical conduction function. For example, it can be implemented as an adhesive that is directly attached to the electrode and can help conduct electricity, or it can be implemented as a conductive patch that is combined with the electrode on the housing. For example, a patch electrode combined with a metal interlocking method, such as a button patch electrode. Therefore, there is no limitation, as long as the housing can be provided on the head, it is within the scope claimed in the present case.

Next, when you want to set it in other positions, according to the electrode and light sensor on the housing The position design is feasible as long as the electrode and the light sensor can be placed in contact with the skin.

Among them, when implemented as a light sensor, it can be set on the wrist to obtain blood physiological information, such as blood oxygen concentration, heart rate, etc. from the wrist, or it can also be set on the forearm or upper arm. The above-mentioned blood physiological information can be obtained, or it can be set on the finger by combining with the finger-wearing structure, especially the finger has always been the most commonly used place to obtain blood physiological information. In addition, it can also be set in reverse. The light sensor is not in contact with the skin. At this time, the blood sensor can also be obtained by touching the light sensor with the other hand. Another option is that the housing can be arranged in front of the torso through the neck wearing structure. In this case, the light sensor can be implemented to contact the torso toward the torso, or can be implemented to contact the hands toward the outside.

When it is implemented as an electrode, it can also be placed on the wrist, forearm, upper arm, etc., through the two electrodes 120 contacting the skin at the same time to obtain skin electrical signals, myoelectric signals, etc., or through the neck structure to be placed in front of the trunk The two electrodes 120 contact the skin of the trunk 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, physiological signals of the head can be obtained, for example, brain signals, eye signals, skin signals, muscle signals, brain Blood flow, and blood oxygen concentration, etc., when placed on the fingers, wrists, upper arms, forearms, front of the torso, you can get cardiovascular-related signals, such as blood oxygen concentration, heart rate, ECG signals, etc. And other physiological information, such as skin signals and myoelectric signals.

Therefore, through this design, even if it is the same device, as long as it matches different wearing structures and is set on different body parts, it can obtain a wide range of various physiological signals, which is quite advantageous for users. select.

In another aspect of the concept, a physiological detection device in the form of a headset is selected.

Earphones are already an indispensable accessory in the daily life of modern people. Therefore, more and more physiological detection devices are implemented as ear-wearing forms. In addition to allowing users to use them naturally, they also make physiological detection more integrated into daily life. For example, the ear-worn form is ideal for physiological testing of sleep, Cardiovascular testing, physiological feedback, neurophysiological feedback and other programs.

In addition, when implemented as an ear-worn form, it can also naturally provide headphone function by combining sound-producing components, which not only can increase the willingness to use, but also contributes to physiological feedback and neurophysiological feedback through sound, which has considerable advantages. Therefore, the ear-worn form described in this article may be various types of earphones available on the market, such as wired earphones or wireless earphones, as well as in-ear headphones, earphones, ear-hook headphones, neck-hook headphones, There are no restrictions on headphones, etc., as long as they meet the conditions described below, they are all within the scope of this case, and the way they provide sound can be changed according to the form of the headset, such as wired Most of the sound from the earphone comes from the portable electronic device connected to it, and the wireless earphone may receive through the Bluetooth connection, or directly store the recording file, MP3, etc. There are various possibilities.

Based on this, a multi-purpose physiological detection device provided by the present invention, in one embodiment, as shown in FIGS. 6A-6C, the form of binaural wearing includes a first ear wearing structure 310 and a second ear wearing Structure 312. The physiological signal acquisition circuit may be provided in the first ear-wear structure, or in the second ear-wear structure, or divided into two ear-wear structures, or another housing may be provided for setting. The circuit, as shown in FIG. 6C, in this case, the other housing can also be used to set control buttons, etc., so there are no restrictions. In addition, one electrode, electrode 330, and electrode 332 are provided on each of the two ear-wearing structures. In addition, the two ear-wearing structures are connected to each other through a connection line 314 to achieve the electrical connection between the electrode 330, the electrode 332, and the physiological signal acquisition circuit.

Here, it should be noted that the way and location of the electrodes will vary depending on the measurement signal. For example, the electrodes can be placed where they come in contact with the skin of the ear, or where they are not in contact with the skin of the ear. In addition, in addition to the method of adding additional electrodes on the surface of the ear-wearing structure, such as electrode pads, it can also be implemented in other forms. For example, the surface of the ear-wearing structure can be directly implemented as an electrode, for example, using The method of coating the conductive layer, or directly using conductive materials (for example, conductive rubber, conductive silicone, etc.) to form the portion, so there is no limitation, as long as it is located on the surface of the ear-wearing structure, the acquisition of electrophysiological signals can be achieved. Are The scope of the invention. In addition, in particular, because the structure of the ear is complex and the structure of each individual is different, it is preferable to implement a single electrode into multiple small-area contact points during implementation to increase the reach of the contact. The probability, for example, can be implemented as an electrode with multiple needle structures, and further, it can also be implemented as having elasticity, for example, using a metal spring connector (pogo pin) as an electrode to adapt to the undulations of the ear structure Changes and differences in different users increase contact stability. Among them, the electrode with multiple needle structures has different implementation options. For example, it can be soldered to a circuit board by multiple conductive needle structures. It can also be formed as a one-piece conductive base and multiple conductive needle-like structures, no matter what the form is, as long as it can provide multiple points of contact and form an electrical connection with a physiological signal acquisition circuit, and then obtain an electrophysiological signal Yes, there are no restrictions.

In FIGS. 6A-6C, the electrode 330 is disposed at a position where the first ear-wearing structure will be in contact with the skin of the ear and / or the nearby area when the first ear-wearing structure is disposed on an ear. As for the electrode 332 on the second The position of the ear-wearing structure may vary according to different use cases. For example, Figs. 6A and 6C show that the electrode 332 is located where it will not contact the skin near the ear, and Fig. 6B shows that the electrode 332 is located where it can be accessed. The location of the ear skin.

In one use mode, the first ear-wear structure is placed on the ear, and the second ear-wear structure is removed. In this case, one option is that the electrode 332 contacts the chest to obtain the projection angle of the heart formed by the ear and the chest, and the other option is that the electrode 332 contacts the hand holding the second ear-wearing structure or passes through the After the second ear-wearing structure is held by a hand, an electrode is brought into contact with the other upper limb to obtain a heart projection angle between the ear and the upper limb. The difference between the two options is that the obtained heart projection angles are different, and because of the design of the connection line, the user can freely choose a suitable and desired measurement position to obtain the best ECG signal.

In another use manner, the first ear-wear structure and the second ear-wear structure are both removed. In this case, one option is to have both electrodes in contact with the chest, and the other option is to have both electrodes in contact with both hands. Similarly, these two options can be obtained separately chest pairs Heart projection angle of chest, and heart projection angle of both hands.

In yet another use manner, the first ear-wearing structure and the second ear-wearing structure are both placed on the ear to obtain the ECG signal. When the configuration shown in FIG. 6A is implemented, the contact between the upper limbs and the electrodes can be achieved by lifting the hands, as shown in FIG. 7A, which is also quite convenient; in addition, it can also be used in the two ear-wearing structures. Electrodes are provided on the exposed surfaces. In this way, as shown in FIG. 7B, the two ECG signals can be obtained by touching two electrodes respectively disposed on the exposed surfaces with both hands.

Still further, it can be implemented that each ear-wear structure is provided with an electrode that contacts the ear and an electrode on the exposed surface. In this way, as long as one hand (left hand or right hand) lifts the contact to the ear-wear structure, The exposed electrode can be combined with the electrode on the other side (right or left) of the ear-wearing structure to form a sampling loop. The advantage of this method is that the ear-wearing structure can be used to capture another ECG signal without removing it from the ear. Moreover, the left hand touches, the right hand touches, or both are lifted at the same time. With two hands touching together, the obtained heart projection angles are different, which can meet different application requirements. Furthermore, in the case where electrodes are provided both inside and outside, since the contact for obtaining ECG signals is achieved by electrodes on different side ear-wearing structures, the inner and outer electrodes of the same ear-wearing structure can be further implemented as a continuous distribution. The same electrode will reduce production complexity and help reduce production costs.

In addition, in a special embodiment, two electrodes are respectively disposed on the exposed surfaces of the first ear-wearing structure and the second ear-wearing structure. In this way, the same can be performed in a manner as shown in FIG. 7B ECG signal measurement. In this case, because the exposed surface has a relatively large contact area, the movement of the ear-wearing structure from the ear and contacting the upper limbs or torso can be more easily achieved. Therefore, there are various possible implementations according to different usage requirements, without limitation.

Here, it should be noted that although the above embodiments mainly take the form of the in-the-ear shell as an example, it is not limited thereto, and the ear-wear structure may be implemented in various forms, for example, an ear clip structure, An ear-hook structure, or a combination of ear-wearing structures, such as an in-ear shell with an ear-hook structure, or an ear clip with an in-ear shell structure, is a feasible option as long as it can provide stable contact, and, The two ear-wearing structures can also be implemented as different types. For example, one ear-mounting structure can be implemented as an ear clip and the other can be implemented as an inner ear shell, so there is no limitation.

Because the two ear-wearing structures are connected through a connecting wire, when at least one ear-wearing structure is implemented to be removed from the ear, the contact position of the electrode becomes very variable, for example, the range of the contactable wire It is possible to obtain the ECG of each position of the twelve-lead electrode separately at all positions within it. Compared with the large number of electrodes and the number of connecting lines required to obtain the twelve-lead ECG, this design is equivalent to a significant reduction. The complexity of setting and the threshold of implementation are quite helpful in achieving a more accurate and detailed judgment of the heart in a simpler way.

Furthermore, in addition to the self-measurement method used by the user, based on the particularity of the structure, the design of the two ear-wearing structures with connecting lines can also be used to obtain the ECG signals of others. For example, the first ear-wearing structure can be placed on an ear of another person so that the electrode contacts the ear and / or nearby skin, and then the electrode is in contact with the torso of the other person by holding the second ear-wearing structure, or Upper limbs, in this way, you can get the ECG signals of others, which is quite convenient. Here, the ear clip structure is particularly suitable for the selection of the first ear-wearing structure, and the operation of setting the ear-wearing structure on the ears of others can be easily achieved.

Furthermore, such a device can also be used to obtain brain electrical signals. In any of the above configurations, as long as both the ear-worn structure has an electrode that can contact the ear and / or the nearby skin, it can be used to obtain the brain electrical signal, so that the same device can provide the ECG signal. There are two functions for capturing and the EEG signal. In addition, the ECG signal can provide different projection angles, which is very advantageous. Among them, when the EEG signal is acquired, the contact position of the electrode is not specified. The limitation is, of course, that it is better to choose to contact the lower part of the auricle, such as the tragus, below the tragus, the earlobe, and the lower half of the earnail wall. The electrode as a reference electrode will be more conducive to obtaining Clear EEG signals.

Furthermore, in addition to the electrodes, a light sensor can also be provided through the ear-wearing structure. For example, it can be set on one side or both sides to obtain blood physiological information, such as blood oxygen concentration and heart rate. In this way, other physiological signal options can be provided in addition to the ECG signal. Here, too, the light sensor will use the reflection method to obtain blood physiological information. In addition, when it is implemented as an electrode contact by the hand In the case of obtaining the ECG signal, the blood physiological information can also be obtained by the hand, for example, the contact with the light sensor is achieved at the same time as the electrode is contacted. In this case, because the heart can be obtained through the electrode at the same time The electric signal and the heart rate are obtained through the sensor, so the pulse wave transit time (PTT, Pulse Transit Time) can be obtained through the correlation between the two types of physiological information, and then the information such as blood vessel hardness / elasticity can be further improved. It is of further significance to estimate blood pressure-related values through calculation.

On the other hand, when the light sensor is implemented near the ear and / or near the ear, it is suitable for performing continuous detection, especially heart rate. For example, it can be used for heart rate monitoring during exercise and also for long-term needs Patients who pay attention to cardiac activity, and through the multi-purpose design of this case, when there is a special need, for example, when they suddenly feel an abnormal heartbeat or the heart feels uncomfortable, the user can immediately touch the electrodes by raising their hands or wear ears Take down the structure and touch the torso or hand, and record the real-time ECG signal, which is very helpful to correctly judge the related heart problems.

Furthermore, according to another implementation concept of the present invention, a multi-purpose purpose can also be achieved through a single ear-wear structure. As shown in FIGS. 8A-8B, two electrodes 330 and 332 are provided on a single ear-wear structure.

In a preferred embodiment, as shown in FIG. 8A, when the ear-wearing structure is worn on the ear, the electrode 330 will contact the ear and / or nearby skin. Therefore, only one upper limb is needed to contact the exposed area. The electrodes 332 on the surface can be used to measure the ECG signals. On the other hand, they can also be removed from the ears and obtained by contacting different body parts, for example, the electrode 330 contacts the holding hand and the electrode 332 contacts the trunk. .

In another preferred embodiment, as shown in FIG. 8B, the ear-wearing structure is implemented to When the ear is removed, the ECG signal is obtained. In actual implementation, there are many options. One option is that the ear-wearing structure can be held by the user's hand and contact the skin of the trunk of the body. For measurement, for example, the two electrodes can be implemented to contact the trunk at the same time, for example, a chest with a strong ECG signal to obtain the ECG signal of the trunk, and another option can be implemented as an electrode contacting the hand held by the electrode Another one contacts the torso to obtain the heart projection between the upper limbs and the torso. Another option is to implement two electrodes to contact both hands to obtain the heart projection between the two upper limbs. Therefore, it is convenient to change the usage mode according to different needs.

Moreover, in order to facilitate the holding of the hand, the ear-wear structure can be formed as shown in FIG. 8B to have an elongated member 316, and the electrodes are disposed on the elongated structure. In this way, while being convenient to hold, It can also achieve contact with the electrodes at the same time, which is more advantageous. In this case, the electrodes provided on the elongated member may be implemented as being distributed on one surface, or distributed on multiple surfaces, or implemented as a continuous distribution.

In addition, in addition to being disposed at a position where the ECG signal can be obtained when the ear-wearing structure is removed, the two electrodes can be further implemented so that when the ear-wearing structure is placed on the ear and near the ear and / or the ear, Skin contact, for example, tragus, earlobe, wall of auricle, bottom of auricle, back of auricle, head (temporal lobe area) around auricle, etc. In this way, the brain can be obtained while wearing the ear The electrical signals increase the use of functions, and, as mentioned earlier, selecting the electrode that contacts the lower half of the auricle as a reference electrode can be more conducive to obtaining stable brain electrical signals.

Still further, it may be implemented with a light sensor 340. For example, as shown in FIG. 8C, it is disposed at a position where the ear-wearing structure will contact the ear and / or the skin near the ear. Among them, a particularly preferred position is the tragus. To obtain blood physiological information, such as heart rate, blood oxygen concentration, etc. while wearing it to the ear, and then provide more physiological information, and when the heart rate information can be obtained through the light sensor, it can be as before It is used to perform continuous detection, for example, for monitoring heart rate during exercise, and / or for patients who need to pay attention to heart activity for a long time, so that when the notification is received, the light sensor detects When it is abnormal, or when you feel you have a special need, for example, When you suddenly feel that your heartbeat is abnormal or your heart feels uncomfortable, the user can immediately remove the ear-worn structure and record the real-time ECG signal by touching the torso and / or hand, which is very helpful to correctly judge the relevant Heart problems.

Here, it should be noted that although the above embodiments mainly take the in-ear shell structure as an example, the invention is not limited thereto, and the ear-wearing structure may be implemented in various forms, for example, an ear clip structure, an ear-hook structure, or It is a combined form of ear-wearing structure, for example, an in-ear shell and an ear-hook structure, or an ear clip and an in-ear shell structure, or an ear-wearing structure can be combined with a supporting connection structure, as long as it can provide stability Contact is a viable option.

Furthermore, such a single-ear structure can also be implemented with a connection port to connect an extension electrode. For example, another electrode can be provided in addition to the original two electrodes. In this way, heart projections of 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 extension electrode. Upper limbs. On the other hand, it can also be implemented as an extension electrode instead of one of the original two electrodes. By increasing the distance between the two electrodes, the position where the electrodes can contact is more variable. For example, you can obtain The electrocardiograms of the twelve leads are also helpful for obtaining more detailed cardiac information. On the other hand, it can be implemented as an extension electrode to obtain another type of electrophysiological signal. For example, the electrode on the original unilateral ear-wearing structure can be used to contact the ear or the head skin near the ear. An ear can also contact the skin of the head near or near the ear to obtain an EEG signal. Therefore, there are various possibilities without restrictions.

As for the implementation form of the extension electrode, various possibilities are possible. For example, it can be implemented by a wearing structure, for example, another ear-wearing structure, a finger-wearing structure, a wrist-wearing structure, a neck-wearing structure, a head-wearing structure, or the like, or a patch, a strap, or the like. In addition, it can also be carried by a holding structure, for example, a rod-like structure, which can be conveniently operated by a user. Therefore, there is no limitation and it can be changed according to actual needs.

In actual use, the extension electrode also has various possibilities. For example, the original ear-wearing structure can be extended from an ear clip structure to carry the extension electrode. In this case, the Place the extended ear clip structure on the ear, and use the original ear-wear structure to contact the trunk or upper limbs; or, you can also extend a finger-wear structure to carry the extension electrode. In this case, you can extend the extension The finger-wearing structure is fixed to the fingers of one upper limb, and then the original ear-wearing structure is used to contact the trunk or the other upper limb: Alternatively, the original ear-wearing structure and the bearing structure of the extension electrode can be held by the hand, and Make contact, for example, by holding hands or by touching 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 are all within the scope of this case.

In another aspect of the concept, the main body is a headset, in order to achieve a multi-purpose purpose. Please refer to FIG. 9A. A multi-purpose physiological detection device includes a head-mounted structure 400 and two ear-mounted structures 410 and 420, which are respectively connected to two ends of the head-mounted structure. In addition, a physiological sensing element is disposed on the head-mounted structure. There are no restrictions on the structure and / or the two ear-wear structures, and the circuit is accommodated in the head-wear structure and / or the ear-wear structures.

Among them, the connection structure between the two ear-mounting structures and the head-mounting structure can have different choices. For example, a connection line can be used for connection. Such a flexible connection method can make the setting of the head-mounting structure more free, or The implementation is to connect the two with a telescopic structure, and such a hard structure connection method allows the head-mounted structure to obtain a further fixing force from the ear-mounted structure. Therefore, no matter which method is selected, it is quite advantageous. In addition, it is preferable that the ear-wearing structure is implemented in the form of an intraauricular shell, so as to pass through the mutual abutment between the inner ear shell and the auricle structure, for example, being plugged into the ear canal or being engaged with the auricle The inner surface of the concave and convex structure and the like to obtain a better fixation effect, but this is not a limitation, but can be implemented in other forms, the focus is suitable for the actual implementation situation.

Here, in particular, the headgear structure is configured to be different from the head, as shown in FIGS. 9B-9C, the headgear structure can be disposed on the top of the head (FIG. 9B), or on the front. The reason for this design is that it is located in the back of the brain (Figure 9C). First, in terms of EEG signals, the cerebral cortex is divided into many regions, and different cerebral cortex regions control different human activities. Therefore, when the electrodes are correspondingly arranged in different regions of the cerebral cortex, When you are in the position, you can get the activities of each area separately. For example, the frontal cortex area corresponds to the frontal cortex, the parietal cortex area below the head corresponds to the occipital cortex area and the ear. The upper part corresponds to the cerebral cortex of the temporal lobe. In addition, in terms of eye movement, the electrodes must be placed around the eye in order to obtain ophthalmic signals. In addition, in terms of skin signals and myoelectric signals, it is the forehead. For a better setting position, according to this, it is only necessary to set the headgear structure at the position where the signal is to be obtained, which is quite convenient.

The physiological sensing element can be implemented as at least two electrodes (not shown) to obtain electrophysiological signals on the head and / or ear. For example, one electrode can be provided on the headgear structure and the other electrode can be provided on one eargear structure. At this time, the electrode provided on the eargear structure can be used as a reference electrode, and when the headgear structure is used, When it is set on the forehead, it can get the EEG signal and the ocular signal, and when it is set on the top of the head and the back of the brain, it can get the EEG signal. According to the position of the electrode on the head structure, the brain can be obtained. Telecommunication signals also have different meanings. For example, even if they are placed on the top of the head or behind the brain, if the electrodes are placed close to the ears, the brain signals in the temporal lobe area will be obtained. If the electrode is placed on the top of the head, the brain electrical signal obtained from the parietal lobe region will be obtained, or if the electrode is placed on the back of the brain, the brain electrical signal from the occipital lobe region will be obtained; or, Both electrodes are set on the head structure. In this case, when the head structure is set on the forehead, the brain electrical signals of the frontal lobe region and / or the brain electrical signals of the temporal lobe region, the ophthalmic signals, and the skin telecommunications can be obtained. And / or EMG signals And when placed on the top of the head and hindbrain, the occipital lobe brain signal, parietal lobe brain signal, and / or temporal lobe brain signal can be obtained; or, another earwear structure can be provided 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 activities of the left brain and the right brain can be obtained respectively. Here, it should be noted that when used to obtain multiple electrophysiological signals, for example, to obtain brain and eye signals at the same time, it can be implemented with only two electrodes, and two types can be obtained from the same channel at the same time. Electrophysiological signals can also be implemented as more than two electrodes, for example, three or four, and two types of electrophysiological signals are obtained from two channels. Therefore, 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 disposed on the headgear structure to obtain blood physiological information of the head. For example, it can be located on the forehead, near the temple, and / or above the ear. Obtain blood oxygen concentration, heart rate, changes in blood flow in the brain, etc., or it can be set on the ear-worn structure to obtain blood physiological information such as blood oxygen concentration and heart rate.

Furthermore, further, the physiological sensing element can be implemented to include both an electrode and a light sensor, and in this case, the above-mentioned various situations are feasible. Therefore, there are no restrictions.

Through this design, the same device can get 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, because it may be necessary to place the electrodes on the top of the head, at the back of the brain, etc., in addition to the general dry electrode form, it is also preferable to implement the electrodes on the head structure. It is needle-shaped, for example, a single needle-shaped electrode, or an electrode with multiple needle-shaped structures to facilitate the passage of hair. Among them, the electrode with multiple needle-shaped structures can have different implementation options. For example, you can It is formed by welding multiple conductive needle-like structures on a circuit board, or it can be an integrally formed conductive base and multiple conductive needle-like structures. There are no restrictions on any form, as long as multiple points of contact can be provided and formed. The electrical connection with the physiological signal acquisition circuit can be used to obtain the electrophysiological signal. Furthermore, it is also preferable to implement the electrode with elasticity. For example, a spring is arranged below the electrode, or a metal spring connector is used ( pogo pin) as an electrode, which will help to adapt to different head shape changes; or, alternatively, it can also be implemented as an electrode replacement, for example, a non-needle electrode was originally used to It is set on the forehead position. When it is necessary to move to the position with hair, it is replaced with a needle electrode. In addition, the material of the electrode need only be a conductive material. For example, conductive metals, conductive rubbers, and conductive fibers are all feasible, so there are no certain restrictions. And, preferably, when placed on the forehead or behind the head, a strap may be externally attached to the headgear structure, for example, connected to both ends of the headgear structure to achieve a better fixing effect.

In all the above-mentioned various embodiments, for example, finger wear, wrist wear, neck wear, head wear, You can add a motion sensing element to the device, such as an accelerometer, a G sensor, a gyroscope, and a magnetic sensor. ), Etc., to obtain the user's body movements or movements at the same time, when analyzing the physiological signals, it can help determine whether the signal quality is caused by the body's movements or movements. In addition, a temperature sensing element can be added to the position where the body temperature information can be obtained, which can help to further understand the actual physiological condition.

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

First, in order to facilitate replacement between different wearing structures, the physiological signal acquisition unit will be formed in the form of a single small casing, as shown in FIG. 10A, that is, all the circuits are accommodated in a single casing 500, so when replacing, you only need to remove the shell from one wearing structure and then attach it to another wearing structure, which simplifies the steps of replacement.

The physiological signal acquisition unit includes a physiological signal acquisition circuit, which is accommodated in the casing 500, and has a first pair of electrical contact areas 510a, 510b on a lower surface 502 of the casing, and a side of the casing. The surfaces 506 and 508 have a second pair of electrical contact areas 512a, 512b. Here, since the volume has been greatly reduced, the area of these electrical contact areas has been correspondingly reduced, for example, reduced to electrical contact. Point form.

Furthermore, since the physiological information provided by different body parts may be different, the physiological signal acquisition unit may further include at least one light sensor 522, as shown in the figure, and disposed on the lower surface 502. Used to obtain the user's blood physiological information, and if the electrodes are also used to obtain electrophysiological signals, it can also provide results based on the correlation between the two physiological signals, such as Pulse Transit Time , PTT), and then can obtain information such as blood vessel hardness / elasticity, and can also be further estimated to obtain data about blood pressure values.

Here, the reason why the electrical contact portions are distributed in this manner is to maximize the possibility of use. For example, one measurement option is to use the first pair of electrical contact areas Get myocardial signal and skin signal, or set it on the chest with strong ECG signal to get the ECG signal. Another measurement option is that the second pair of electrical contact areas can be extended to touch more locations to obtain Other electrophysiological signals, such as brain electrical signals, ocular electrical signals, skin electrical signals, myoelectric signals, electrocardiographic signals, etc. Therefore, through this design, it can be adapted to the different sampling requirements of various settings, which is quite advantageous.

Of course, the configuration shown in FIG. 10A is only one of the configurations of the electrical contact area and the light sensor, and other configuration options are also possible. For example, as shown in FIG. 10B, an additional power supply may be added to the upper surface 504. The contact area 514, or may include only two electrical contact areas (similar to the situation shown in FIG. 3C), and may be disposed on the same surface and / or on different surfaces as the light sensor. Usage requirements vary and there are no restrictions. In addition, other sensing elements, such as a temperature sensing element, can be added to the position where the body temperature can be obtained, which is also not limited.

When there is an electrical contact area 514 on the upper surface, it provides another option for direct exposure. Such a configuration is quite conducive to obtaining ECG signals. For example, no matter where it is placed on the body, as long as the electrical After the contact area 514 is exposed, it can be easily contacted through one hand, and then cooperate with any of the electrical contact areas 510a, 510b, 512a, and 512b to make contact with the skin of another part of the body (directly contact or extend) And contact), forming a sampling circuit of the ECG signal, is also a quite advantageous implementation.

In this case, when it is intended to be placed on different parts of the body, such as fingers, wrists, arms, neck, chest, head, ears, as long as it is combined with different wearing structures, for example, finger wearing structures , Wrist-wear structure, arm-wear structure, neck-wear structure, head-wear structure, ear-wear structure, patch, straps, etc., can meet the needs of the setting.

In addition, because the sampling positions of different parts are different, and the setting conditions are also different, further, the electrode can be set to the most appropriate sampling position through the wearing structure. In this case, it is preferable that A coupling structure which can be combined with the shell is provided on the wearing structure Structure, for example, an accommodating slot, and an electrical contact portion corresponding to an electrical contact area on the housing is provided in the coupling structure, so that after the housing and the coupling structure, the electrical contact area on the housing and the coupling structure The electrical contact part inside can achieve electrical connection. On the other hand, as long as an electrode electrically connected to the electrical contact part is provided on the surface of the wear structure, the electrical contact area on the housing can be electrically connected to the electrode on the wear structure. In this way, the positioning and fixing of the electrodes can be achieved directly by using the wearing structure, which is quite convenient.

Here, it should be noted that when the electrical contact area on the physiological signal acquisition unit is directly used to contact the skin to obtain a physiological signal, it is regarded as a signal acquisition electrode. On the other hand, when it is When it is used to make contact with the electrical contact part in the wearing structure to achieve the electrical connection between the electrode and the circuit on the wearing structure, it is considered as an electrical contact. It depends entirely on the actual implementation situation. There are no restrictions and therefore , The same electrical contact area on the shell may have different functions when it is matched with different wearing structures.

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

First, in the simplest case, the physiological signal acquisition unit is set on a finger of a user through a finger-wearing structure. Here, the setting position may be a fingertip, or a proximal phalanx or a middle phalanx. There are no restrictions on the knuckles, and there is no restriction on which finger, as long as the corresponding suitable finger-wearing structure is provided. For example, as shown in FIG. 11A, if a finger-type finger-wearing structure 600a is used, it can be set. For fingertips, if a ring-shaped finger-wearing structure is used, it can be set at the position of the knuckles. If a finger-clip-shaped finger-wearing structure is used, it can be clipped to the fingertips as long as the shape is suitable. At the festival, the implementation form can be changed according to actual needs. Furthermore, it can also be implemented as a fixed structure made of viscous and soft materials, such as patch, patch, devil felt, etc., suitable for installation on any knuckle. .

In addition, in terms of size, it is preferably minimized if it is adapted to be placed on a finger. For example, the size of the housing is best 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 that even if it is placed on the finger, it will not feel obtrusive and burdensome.

When the physiological signal acquisition unit is set on a finger, the most suitable physiological signal acquisition is to use a light sensor to obtain blood physiological information from the finger, such as blood oxygen concentration, heart rate, blood flow, and so on. It is generally the most well-known place for obtaining blood oxygen concentration.

Here, it should be noted that, as mentioned above, the blood oxygen concentration sensors commonly used in the market generally use two measurement methods, transmissive and reflective. Among them, transmissive, as shown in Figure 2A, is The light-emitting element and the light-receiving element are placed on both sides of the finger to measure the light so that it can 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 FIG. 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 simpler structure and relatively low power consumption. Therefore, both methods have their own advantages and can be used.

Therefore, when adopting the form of a single housing, it is preferable to use a reflection method for measurement, that is, the light emitting element and the light receiving element are disposed on the same side of the finger. On the other hand, if the wear structure has physiological characteristics For sensing elements, for example, when a light-emitting element is placed on the housing and a light-receiving element is extended to the wearing structure, it can be measured through penetration. Therefore, no matter where it is placed on the finger, it is a requirement There are no restrictions on whether to use the transmission method or the reflection method for measurement.

Here, it should be noted that the finger-wearing structure used can be in any form that can be fixed to the finger, as described above, for example, a ring structure, a finger sleeve structure, a finger clip structure, a surrounding structure, etc., without limitation . On the other hand, there can be various choices of materials, for example, elastic materials such as silicone, rubber, etc .; or flexible materials, which can be fixed by winding, such as devil felt; or It is also possible to further add a viscous substance to fix it by means of adhesion; or a hard material with finger ergonomic structure can also be used, for example, plastic formed in the form of a clip, or plastic formed in the form of a ring , Metal, etc .; Alternatively, different materials can be used in combination, for example, a hard material can be coated on the elastic material; or it can be implemented in a disposable form. Therefore, there are various possibilities without restrictions.

As for the combination between the shell and the finger-wearing structure, there can be various options, for example, it can be implemented in various feasible ways such as embedding, snapping, magnetic attraction, adhesion, and attachment. There are no restrictions, as long as the combination and Just fix it.

For example, in one embodiment, the finger-wear structure is implemented as a fingertip cover made of silicone (similar to the structure shown in FIG. 11A), and the housing can be simply embedded directly into the fingertip cover. It can be inserted into the groove, which is not only easy to manufacture, easy to fix and locate, but also very comfortable to use. In another embodiment, the finger-wear structure can also be made of resilient elastic materials, and can be opened by the design of the structure. Combined with the effect of fixing, and then fixed, as shown in Figures 11B-11C, the shell can be plugged into the elastic finger structure 600b; in another embodiment, the finger structure is implemented as an adhesive non-woven fabric , Can be used to surround the knuckles, or can be used to stick to the fingertips. In another embodiment, the finger wear structure is implemented as a devil felt, which can be freely adjusted and adapted to different finger sizes; in another embodiment, as shown in the figure As shown in 11D-11E, the finger wear structure is implemented as a ring-type finger wear structure 600c, and the combination of the shell and the ring can have various possibilities, for example, by means of snapping, plugging, magnetic attraction, etc .; In yet another embodiment, the finger-wear structure is implemented as an inner Elastic material is used, and the exterior is covered with hard material, such as a plastic case. In this way, the elastic material can be used to achieve the finger curve to stabilize the setting of the physiological sensing element, while also providing a suitable and beautiful exterior Type, and even an exposed electrode can be set through a hard material casing and connected to one of the electrical contact areas on the physiological signal acquisition unit. In this way, the ECG signal can be measured.

Such a setting is particularly suitable for use during sleep to detect sleep physiological state information, such as breathing conditions and sleep quality. This is because when adopting such a design, not only the volume is small, but the structure provided on the finger is also quite simple, it is not easy to fall off, and it will not cause obstacles during sleep, but it can obtain blood oxygen concentration very surely. And heart rate, among which blood oxygen concentration can be used to understand breathing during sleep to provide information about sleep calls. Information on Sleep Disordered Breathing (SDB), such as Obstructive Sleep Apnea (OSA), and heart rate, which can be used to understand other physiological information during sleep, such as cardiac activity and other physiological information derived from it Information, such as the time to fall asleep, and further, if the housing is also equipped with a motion sensing element, it can also detect the movement of the hands and body, etc., which are closely related to the quality of sleep, so , Quite an advantage.

Furthermore, if it is used during sleep, in order to allow the user to use it comfortably, the surrounding range of the finger structure can be extended to a part of the palm. For example, as shown in FIG. 11F, the surrounding finger structure 600d The part around the palm under the thumb has been added. In this way, through a larger area of fixation, the user can feel more stable and will not affect sleep. Of course, the actual implementation of the finger structure is shown in Figure 11F. By way of example, not limitation, as long as the structure that surrounds a part of the palm at the same time is within the scope of the present claim, there is no limitation.

On the other hand, in addition to the blood physiological information obtained using the light sensor described above, the electrodes can also be used to obtain the electrophysiological signal. As mentioned above, due to the small volume of the case, the contact area of the electrical contact area is small, and the distance between the two electrical contact areas is close. In addition to being possible to directly obtain myoelectric signals and skin electrical signals, it is necessary to obtain other electrical signals. In the case of physiological signals, or when the acquisition position of myoelectric signals and / or skin electrical signals cannot be achieved directly from the housing, the electrode and skin contact can be further achieved by changing the fingering structure.

In practice, the finger-wearing structure is implemented as having a bonding structure for receiving the housing, and having an electrode on an accessible surface and electrically connected to an electrical contact portion located within the bonding structure. In combination with the bonding structure, the electrical contact area on the original housing can be extended to the electrodes on the finger structure. Here, it should be noted that, depending on the actual measured physiological signal and the position to be set, the extension of the electrode can be implemented to extend only a single electrode, or both electrodes can be extended outward. Way of implementation.

Among them, when used to obtain skin or myoelectric signals, only one electrode can be extended. To lengthen the distance between the electrodes, both electrodes can also be extended through the finger wear structure to be set to different positions.

In addition, when used to obtain the ECG signal, since one electrode must contact other parts of the body except the limb where the finger wearing the housing is located, at least one electrode must be extended through the finger structure. In practice, There are many different options. For example, in one embodiment, one electrical contact area on the housing can be brought into contact with a finger, and the other electrical contact area is extended to the exposed surface through the finger-wearing structure to contact other body parts; in another embodiment It can also be implemented that both electrical contact areas are extended through the finger-wearing structure to contact the fingers and other body parts, respectively. Therefore, there are various possibilities without restrictions.

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

Furthermore, the casing can also be implemented in combination with a head-mounted structure, as shown in FIG. 12A, to be placed on the user's head. As is well known, the head can obtain many physiological signals. For example, electrodes can be used to obtain brain signals, eye signals, skin signals, muscle signals, etc., and light sensors can be used to obtain blood flow in the brain. Changes in blood oxygen concentration, heart rate, etc., among which changes in brain electrical signals, ocular electrical signals, and blood flow in the brain are physiological information that can only be obtained on the head, and are therefore important physiological monitoring locations.

In this case, there are some restrictions on the position of the electrodes for obtaining the EEG signal. For example, the electrodes are generally set according to the international 10-20 system. In addition, the ophthalmic signal It is also necessary to set the electrodes around the eyes, so it is suitable to use the electrode extension design described above to set the electrodes to the desired position through the head-mounted structure.

During implementation, similarly, as shown in FIG. 12B, the head-mounted structure 700 is implemented with a coupling structure 710 for receiving the housing, and in particular, on the coupling structure, there will be The electrical contact portions of the contact area 510b and the electrical contact area 512b are electrically contacted at the same time, and then electrically connected to the connection area through a connection line provided along the headgear structure. The extension electrode 740 provided on the headgear structure can obtain the EEG signal very simply even if the volume of the case according to the present case is very small.

And, as long as the form of the headgear structure is changed, for example, the shape of the headgear can be changed, the electrodes can reach any head area and obtain the brain electrical signal of the cerebral cortex area in the relative position. For example, when it is set in the front Forehead time, you can get the brain signal in the frontal lobe area. When you set it on the top of the head, you can get the brain signal in the parietal area. Electrical signals, and when placed behind the head, brain electrical signals can be obtained from the occipital region. As we know, different areas of the cerebral cortex are responsible for different functions of the human body, so the monitoring of each cerebral cortex area has its significance.

As for the form of the headgear structure, you can have different choices depending on the position of the signal you want to obtain. For example, if you want to set it on the forehead, you can simply use the form of patch, cloth, and adhesive to reduce the burden. It adopts the form of straps or a head frame with clamping force. If it is to be placed on the top of the head, it can be used in the form of a head frame and a hat. In addition, if you want to get the ocular signal, you can set it on the forehead or extend down to the eyes. Therefore, there is no limit and it can be changed according to actual needs.

Among them, a special form of the headgear structure is an eyeglass structure. In general, when the eyeglass structure is worn on the head, the positions that it will touch include the bridge of the nose and the ears, and in some cases, it will also touch around the eyes. Therefore, this configuration is very suitable for obtaining ophthalmic signals. Frontal lobe brain electrical signals, and temporal lobe brain electrical signals. Moreover, since the volume of the casing according to the present invention can also be implemented to be small, it is also quite suitable for being incorporated into the structure of glasses.

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 electrical contact areas can be extended outward. For example, when the headgear structure is provided on the forehead or the headgear structure is implemented as an eyeglass structure, an electrical contact area on the housing can be directly used, and only one electrical contact area is extended. Therefore, there is no limitation. .

This setting is also very suitable for use during sleep. For example, the most important basis for determining the sleep stage is the brain signal, such as Rapid Eye Movement (REM), deep sleep, light sleep, awake, etc. In addition, myoelectric signals and ophthalmic signals are also used to determine whether it is in the rapid eye movement period, and these are commonly used physiological information to determine the quality of sleep. Furthermore, the blood oxygen concentration obtained by the light sensor is available In order to obtain the breathing situation during sleep, for example, when there is a sleep apnea, it is usually accompanied by a decrease in blood oxygen concentration, so you can determine whether sleep apnea occurs by observing the blood oxygen concentration. In addition, the obtained heart rate can be understood Physiological state during sleep, such as the state of autonomic nerves, the state of heart activity, whether arrhythmia occurs, etc., can also be used to determine the time of sleep onset, etc. In addition, motion sensing is also provided in the casing Components, it can also detect the user ’s actions such as turning over, so almost all the physiological signals obtained by sleep inspection are included Furthermore, only a small volume of the headset housing mating structure can be completed without complicated wiring, having a considerable advantage.

Furthermore, the casing can also be implemented in combination with a neck-wear structure 800. As shown in FIGS. 13A-13B, through the neck wearing structure, the housing can be set in front of a user's torso, and in the case of being set in front of the torso, it is very suitable for obtaining ECG signals. The size of the housing is small and the distance between the two electrical contact areas is short. Therefore, the electrical contact area can be extended through the combined structure of the neck-wear structure and the housing. For example, as shown in FIG. 13B, only Extend one electrical contact area to the electrode 810, or, as shown in FIG. 13A, both electrical contact areas extend to the electrode 810, so that the distance between the electrodes is enlarged, which is suitable for obtaining ECG signals in front of the trunk. In this case, Next, the user can easily obtain the ECG signal as long as the user presses the combination of the casing and the coupling structure located in front of the drive shaft.

In addition, the light sensor in the housing can also obtain blood physiological information, such as blood oxygen concentration, pulse wave signal, heart rate, etc., from the trunk or through hand contact, and when the heart can be obtained at the same time In the case of electrical signals and pulse wave signals, as described above, the pulse wave transmission time can be obtained to obtain information such as blood vessel hardness / elasticity, and then the relevant blood pressure values can be estimated.

In addition, the casing can be implemented in combination with an ear-wearing structure. Because the volume of the casing is very small, when placed on the ear, the volume is not significantly different from the volume of headphones currently on the market, which not only causes no burden but is also not obvious.

On the ear and / or near the ear, blood oxygen concentration, pulse wave signal, heart rate, etc. can be obtained through the light sensor, and brain electrical signals, myoelectric signals, skin signals, ECG signals, etc. can be obtained through electrodes. There are also various options. The setting of the light sensor only needs to contact the ear or the skin near the ear, and the brain electrical signal, myoelectric signal, and skin electrical signal can contact the ear and / or the skin near the ear through two electrodes, respectively. And obtained, as for the ECG signal, it is preferably implemented that one electrode contacts the ear or the skin near the ear, and the other electrode extends to the exposed surface for an upper limb to contact.

As for the form of the ear-wearing structure, there are also various possibilities. Whether it is an in-ear shell form, an ear-hook form, or an ear-clip form are all feasible ways, and according to different forms, the materials used can also have corresponding The changes will change the electrode and light sensor settings. For example, when implemented in the form of an in-ear shell, it can be implemented by covering the shell with a resilient material, such as silicon rubber, so as to adapt it to the depressions and protrusions on the inner surface of the auricle. At this time, the electrode can be It is directly exposed through the hole of the covering material, and the extended form as described above can also be used to achieve contact with the skin. When it is implemented as an earhook, it will have a pendant hanging above the auricle, so it will increase. It is possible to touch the back of the auricle and / or the head near the ear. At this time, the electrode can be extended to the pendant by extension. As for the housing, the position can be set in front of the auricle, or Behind the auricle are optional positions; when implemented as an ear clip, the electrode can be extended to the inner surface of the ear clip to contact the skin of the part where the ear is clamped, such as the ear lobe, the edge of the auricle, etc. The electrode can also be extended to the exposed surface of the ear clip for upper limb contact. As for the light sensor, no matter what kind of ear-wearing structure is adopted, it only needs to be ensured that it can be exposed and can be contacted and fixed on the skin. Therefore, it is a feasible method without limitation.

Furthermore, the casing can be implemented in combination with a wrist-worn structure 900, as shown in FIG. 14A-14B. Near the wrist, blood physiological signals such as pulse wave signals, heart rate, and blood oxygen concentration can be obtained through a light sensor, and electrophysiological signals such as muscle electrical signals, skin electrical signals, and cardiac electrical signals can be obtained through electrodes. Among them, The acquisition of myoelectric and skin signals requires two electrodes to contact the same part of the skin at the same time. In addition, the acquisition of ECG signals can be implemented as one electrode contacts the skin near the wrist and the other electrode extends to the exposed surface to For contact with other body parts, such as the other upper limb, torso, etc.

Here, due to the small volume of the housing, the shape of the wristband 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 Use habits and choose the form of wrist structure you want.

The configuration of the electrodes and the light sensor is similar to the above. Among them, the light sensor needs to be exposed and set in a position that can be contacted and fixed on the wrist. As for the electrode, it can be implemented by directly exposing the electrode 514 on the case to achieve contact, as shown in FIG. 14A, or by using the wrist The electrode 910 extending on the structure, as shown in FIG. 14B, is not limited.

Here, it should be noted that the above-mentioned wearing structure is merely an example, not a limitation, and the wearing structure that the shell according to the present invention can fit is not limited as long as it can be combined with the shell and attached to the shell. The wearing structure on the surface of the human body, such as an arm-wearing structure, a chest strap, a leggings band, a patch, etc., all belong to the application scope of this case, and there are no restrictions.

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

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

Furthermore, when the above-mentioned device is applied to detection during sleep, especially when implemented as a finger-wearing form, in addition to the case where the above-mentioned wearing structure is detachable from the housing, it can also be implemented as an integrally-shaped finger-wearing structure 600e, such as As shown in FIG. 15, a housing sandwiched between fingertips or a finger-wearing structure directly fixed through a ring is a feasible method, without limitation, 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 can reflect the physiological state of sleep. For example, the blood oxygen concentration can be used to determine whether there is a situation of hypopnea, such as shallow breathing, apnea, etc. This is because when there is hypopnea, the amount of oxygen in the blood will decrease. Therefore, you can learn the changes in breathing during sleep by observing the changes in blood oxygen concentration. Furthermore, heart rate can be used to help observe the physiological state during sleep, such as , The state of the autonomic nerve, the state of cardiac activity, whether arrhythmia occurs, etc., can also be used to determine the time to sleep (sleep onset); further, if additional motion sensing elements, such as an accelerometer, can provide body movement Information. Therefore, even if it is only a small-volume device worn on a finger, a lot of information about the physiological state of sleep can be obtained by combining the above information, such as sleep quality, which is particularly suitable for understanding whether there is a sleep disordered breathing (Sleep Disordered Breathing (SDB), for example, Obstructive Sleep Apnea (OSA).

On the other hand, after learning about their own sleep situation, if it can provide programs that help to fall asleep and / or help relieve pressure at the same time, it will be a more complete solution for users.

In recent years, more and more studies have shown that the human body can influence the body's operating system through self-conscious regulation to achieve the effect of improving physical and mental health, for example, triggering a relaxation response in the body. The so-called relaxation response can be said to be a physical response that is complementary to the fight-or-flight response. Generally speaking, the relaxation response occurs when the body no longer senses danger. At this time, the autonomic nerve Sympathetic nerve activity will decrease in the system, and this response can be achieved through meditation, breathing training, biofeedback, and progressive muscle relaxation 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 human body can change physiological activities 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 quickly and accurately returned to the subject. Since this information is related to the desired physiological changes, After obtaining the information, the test subject can perform self-conscious regulation to strengthen the required physiological response and / or improve their own physiological status.

And through the configuration of the electrodes and / or other physiological sensing elements in the physiological detection device described 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. are all Physiological signals often used in physiological feedback programs.

Among them, when the alpha wave is dominant, it means that the human body is in a relaxed and awake state, when the beta wave is dominant, it means that the human body is awake and nervous, and when the θ wave is dominant, it means that the human body is in a relaxed and conscious state. Therefore, the physiological and conscious state of the human body can be known by observing the changes in brain waves; the myoelectric signal represents the tension of the human muscle, and the muscle tension is also related to the activity of the autonomic nerve, so it can be known based on the The degree of stress; the electrical activity of the skin is related to the activity of the sweat glands, and the secretion of the sweat glands is only affected by the sympathetic nerves. When the activity of the sympathetic nerves increases, the activity of the sweat glands increases. Decrease, and as is well known, 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 nerve and the parasympathetic nerve, and when the sympathetic nerve activity increases, The heart rate becomes faster, and when parasympathetic nerve activity increases, the heart rate becomes slower, so you can observe the heart rate sequence Learn about the increase and decrease of the activity between the two; In addition, because the blood vessels transmitted to the skin at the end of the limb are only affected by the sympathetic nerves, and when the activity of the sympathetic nerves is reduced, the vasoconstriction decreases, the tube diameter becomes larger, the blood flow increases, and the skin surface temperature Rise, so the activity of the sympathetic nerve relative to the parasympathetic nerve can also be inferred by measuring the skin temperature at the end of the limb For example, the temperature may be measured through a temperature sensing element.

And 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 human autonomic nerve. Blood physiological information or body temperature information are suitable for physiological feedback procedures. For example, physiological feedback can be performed before bedtime to achieve a physiological state that helps sleep. For example, physiological feedback can be used to increase the brain wave. The proportion of alpha waves is used to induce sleep. In addition, physiological feedback can also be provided during leisure time. 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 invention only needs to further cooperate with an information providing unit to provide relevant acquired physiological signals to the user through a notification message, so that the user can know the physiological changes in real time, and then Achieve the settings needed to perform the physiological feedback program.

For example, an information providing unit can be set directly on the physiological detection device to provide information through various notification methods that can be perceived visually, audibly, and / or tactilely. Perceived methods, sound and speech audible methods, and / or vibration and temperature changes such as tactile sensible methods, can be achieved by installing heating elements, vibration elements, sound generating elements, display elements, etc., there are various possibilities, no limit.

Moreover, based on the multi-purpose characteristics of the device according to the present invention, the user can also choose a physiological signal as a basis for physiological feedback based on different feedback purposes or different usage habits. For example, as long as the finger-wearing structure is selected, You can get body temperature information, blood physiological information, and / or skin electrical information from your fingers, and you can simply provide relaxed physiological feedback, which is quite convenient.

Furthermore, when the wearable physiological detection device according to the present invention is used, simply wearing the wearable structure, for example, wearing a ring, glasses, headphones, a bracelet, etc., is equivalent to completing a physiological sense. The setting of the measuring element, then, just start the physiological test and obtain the real-time physiological information through the information providing unit, and the physiological feedback can be performed, which is quite convenient, and because of such a simple and convenient setting, there is almost no time when using Restrictions on locations, eg For example, during commuting, before going to bed, etc., it is a time and place where physiological feedback can be performed, which is quite helpful for increasing the user's willingness.

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

Of course, in addition to the physiological feedback period, the information providing unit can also be used to provide other notifications and instructions related to the user during other wearing periods, for example, when the detected physiological signal meets a preset condition For example, the heartbeat is fast, arrhythmia occurs, the blood oxygen concentration is too low, etc., and the user is reminded through various methods such as sound, vibration, and flash, so there is no limit.

In addition, the information providing unit can also be implemented as an external device, such as a smart phone, smart watch, tablet, 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 smartphone, for example, through a mobile phone Run an application (APP) to communicate with the physiological detection device worn on the body. The above-mentioned various methods, whether visual, auditory, or tactile, can be achieved with a mobile phone, which not only reduces the burden on the hand, Also, since various portable electronic devices such as smart phones and tablets have been fully integrated into the daily lives of ordinary users, it is also relatively easy to operate without additional learning.

In addition, the wireless communication can be used for simple information transmission in addition to the physiological feedback period, such as the captured physiological signals and detection results. In this case, it can be It is implemented as real-time wireless transmission, or implemented after the physiological monitoring is completed. There is no limitation. Therefore, a memory can be set in the casing to store the acquired physiological signals and download to the external device after the monitoring is completed. Of course, the memory can also be used as a buffer memory before wireless transmission, without limitation.

Here, it should be noted that this wireless communication and memory can be implemented in the devices in all the aforementioned embodiments of the case, that is, any device mentioned so far in this document can be further configured with a wireless transmission module to perform Wireless communication with an external device, 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's body through the wireless communication, and There is no limit to the configuration of a memory, and such a configuration further improves the convenience and performance of the wearable form, which is quite advantageous.

In summary, the present invention provides the concept of a multi-purpose physiological detection device. With different wearing structures, it can be conveniently and simply installed on different body parts under the condition of using the same device, thereby obtaining different physiological signals. It is not only cost-effective, but also allows users to change the use mode according to different needs, and then obtain the most suitable physiological signal.
