In the concept of the present invention, in order to achieve the purpose of multi-purpose, the method adopted is to concentrate the circuits, components, and physiological sensing components required for physiological signal detection on the same housing as much as possible. , Just by changing the wearing structure, you can easily Change the setting position or setting method of the housing to obtain different physiological signals.

Accordingly, the multi-purpose physiological detection device according to the present invention has a housing as the main body, which is mainly used for accommodating circuits/components and arranging physiological sensing components. As shown in FIG. 1, the multi-purpose physiological detection device according to the present invention includes a physiological signal capture circuit 110, and is electrically connected to physiological sensing elements, such as electrodes, and/or light sensors, to obtain physiological signals , Here, it should be noted that the physiological signal acquisition circuit will include all necessary circuits and components to obtain physiological signals, such as processors, analog signal processors, analog-to-digital converters, filters, memory The body, battery, etc., are already well known by those with ordinary knowledge in the field, so I won’t repeat them. In addition, if there is a wireless transmission requirement, for example, to transmit the acquired physiological signal to an external device, it can also be The wireless transmission module is included, or the memory can also be implemented in a removable form. Therefore, different circuits, components, and/or modules, etc., can be provided according to actual needs, which are all within the scope of the present invention and are not limited.

As for the type of physiological sensing element used, there is no certain limit, and it can be determined according to actual needs. For example, it can only include at least two signal extraction electrodes to obtain electrophysiological signals, such as ECG signals, brain signals, ocular signals, myoelectric signals, skin signals, etc., or only light sensing Detector to obtain blood physiological information. For example, when there is one light source, heart rate, blood flow, etc. can be obtained, and when there are more than two light sources, blood oxygen concentration can be obtained. Of course, it can also include signal extraction electrodes. And the light sensor, so there is no limit.

Here, it should be noted that generally when capturing electrophysiological signals, signal extraction electrodes and ground electrodes are often installed. Among them, the signal extraction electrodes are used to obtain electrophysiological signals, and the function of the ground electrodes is to remove the background. Noise, and all the electrodes described in this article are signal extraction electrodes. However, in order to avoid too long words, in the following description, "electrodes" are used to represent "signal extraction electrodes", as for grounding The setting of the electrode is generally set selectively according to actual needs, so I will not repeat it in this article. In addition, in order to make the description more concise, when the electrode is used to obtain a specific type of electrophysiological signal, Will be directly described as this type of electricity Electrodes for physiological signals, for example, ECG electrodes, brain electricity electrodes, eye electrodes, myoelectric electrodes, skin electrodes, etc.

In addition, the electrodes mentioned here are generally known conductive materials that can sense the self-generation of the human body, such as metals, conductive fibers, conductive rubber, conductive silicone, etc., so in the following description, only for The installation position, installation method and shape of the electrode are described.

In addition, a light sensor refers to a sensor that has both a light emitting element and a light receiving element. It emits light through the light emitting element and enters the human tissue, and the light penetrates the blood in the blood vessel or through the blood. After being reflected, 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.

Generally speaking, when it is implemented to obtain blood physiological information through a penetrating method, as shown in FIG. 2A, the light emitting element 122a and the light receiving element 122b are respectively arranged on both sides of the measurement site, such as 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 placed on the same side of the measurement site, for example, the finger. In addition, when the placement position is between the above 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 wearable structure, without limitation, the physiological sensing element can also be arranged on the wearable structure, and the advantage brought by this is that it can be achieved by replacing the wearable structure, for example, Various options such as changing the types of physiological sensing elements, increasing or decreasing the number of physiological sensing elements, and changing the arrangement positions of the physiological sensing elements are also quite advantageous. As for the detailed implementation manners, described later.

First of all, in the first aspect of the case, a multi-purpose design with fingers as the mainstay was chosen.

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

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

Therefore, it is very convenient that the user can perform physiological testing only by wearing the ring, and because the ring is used in a form that hardly hinders daily life and is not obtrusive, it is very suitable for daily use.

Here, the form of the finger-wearing structure is not limited, as long as it can maintain the housing on the finger and achieve the arrangement of the physiological sensing element at the same time. For example, it can be a ring structure, a C-shaped structure, etc., for example, Finger ring structure, finger clip structure, finger sleeve structure, strap structure, etc. are all available methods. In addition, the material can also have different options, for example, it can be implemented as a hard material, such as plastic, metal, etc., or it can be implemented Flexible materials and/or elastic materials, such as silicone, rubber, cloth, etc., are all feasible methods. That is, the various finger-wearing structures mentioned above can be made of hard materials, or There are no restrictions on soft/flexible materials or mixed materials.

Next, as long as the shell is implemented to be separable from the finger-wearing structure, it can be realized for multi-purpose purposes. One option is to install on other parts of the body through another wearing structure. For example, it can be installed on the torso through a patch structure or a neck wearing structure. In this case, The electrodes originally arranged on the same surface can touch the torso at the same time to obtain ECG signals, myoelectric signals, and/or skin signals, or the electrodes arranged on the opposite surface can touch the hand and the torso separately by pressing with one hand To obtain the ECG signal, the light sensor can obtain blood physiological information from the torso or from the hand that is in contact; or it can also be set on the wrist through the wrist-worn 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 ECG signals by touching the wrist and another part of the body, such as the other hand or the torso, and set them in the same The electrodes on the surface can obtain myoelectric signals, skin signals, etc. from the wrist. Moreover, because it was originally implemented as a finger-worn form, when the shell is placed on the wrist, the volume will be very small, similar to that of a bracelet I feel that the burden is quite small.

Another option is to change the size of the finger-wearing structure to adapt to different finger sizes or fingers of different users, especially when the finger-wearing structure is implemented in the form of a ring, such as a ring, because it is rigid The structure has limitations on the adaptation of different fingers. Therefore, if the ring body of different sizes can be replaced, a single device can be easily adapted to fingers of different sizes. In this way, except for the fingers that the same user can freely choose In addition, different users can share and use the same device, which is very cost-effective.

In actual implementation, one of the implementations is that the replaceable finger-wear structure is implemented as a simple structure without physiological sensing elements. In this case, electrodes, light sensors, and The physiological signal capture circuit, etc., are all arranged in a shell that can be combined with the finger-wearing structure, that is, the shell and the finger-wearing structure are only mechanically combined, wherein the light sensor can be set When the shell is combined with the finger-wearing structure, it faces the finger or the outward direction. In addition, the setting of the electrode varies according to the physiological signal obtained. For example, if it is used to obtain an ECG signal, One electrode needs to be in contact with the finger, and the other electrode is exposed for contact with other parts of the body. If used to obtain myoelectric signals and/or skin signals, the two electrodes need to be on the same surface, for example, touching the fingers at the same time, or at the same time Expose and touch other parts of the body.

Furthermore, another implementation option is that the replaceable finger-wearing structure is implemented with physiological Sensing components, such as light sensors and/or electrodes, at this time, mean that in addition to the mechanical connection between the finger-wearing structure and the housing, an electrical connection is also required to enable the physiological sensing on the finger-wearing structure The component can be electrically connected to the physiological signal capture circuit in the housing. 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. There are no restrictions on design changes. As mentioned above, the light sensor includes a light emitting element and a light receiving element. Therefore, when it is installed on the finger-wearing structure, it can be selected to use a penetration method or a reflection method to obtain blood physiological signals. feasible.

In addition, in a special embodiment, another special implementation can be produced by changing the material of the finger-wearing structure. When the finger-wearing structure is implemented as a metal material, as shown in FIG. 3C, for example, a common stainless steel ring can be made by contacting the finger-wearing structure with one of the electrodes on the original housing to make 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 housing. Therefore, such a setting is particularly suitable for capturing ECG signals. The advantage brought by this is that the structure of the finger-wear structure becomes quite simple, no additional electrical connection wires and electrodes are required, the manufacturing procedure can be simplified to the greatest extent, and the manufacturing cost can also be reduced.

In this case, it should be noted that the material of the finger-wear structure is not limited to metal materials, as long as it is a conductive material that can be combined with the housing and set 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 coated with other materials to create visual effects. Therefore, 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 it is only necessary to provide ECG signal measurement, it can be directly implemented in a form in which the conductive finger-wearing structure and the housing are inseparable, so that the housing is fixed to the finger-wearing knot In terms of structure, this will be more cost-effective.

In another aspect of the idea of this case, the choice is a multi-purpose setting option with the head as the mainstay.

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

Accordingly, in this embodiment, as shown in FIGS. 4A-4B, the physiological sensing element is arranged on the lower surface 101 of the housing. For example, FIG. 4A shows a situation where two electrodes 120 are arranged, and FIG. 4B shows a light arrangement. In the case of the sensor 122, in this way, the setting method shown in FIG. 5 can be used to obtain physiological signals from the head. For example, in Figure 4A, brain signals, eye movement signals, and skin electrical signals can be obtained. , Myoelectric signals, etc., and Figure 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, in addition Furthermore, it can also be implemented to provide electrodes and light sensors at the same time to obtain more physiological signals. For example, it can be implemented to arrange electrodes and light sensors on the same plane or on different planes. There are no restrictions.

Here, the shell set on the head is set by a head-wearing structure, for example, it can be straps, helmets, hats, glasses, patches, glue, etc., all of which are optional. In addition, In particular, the head-mounted structure can also be implemented as an electrically conductive function, for example, as an adhesive that is directly attached to the electrode and can help conduction, or as a conductive patch that is mutually 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 shell can be installed on the head, it falls within the scope of the claim.

Next, when you want to set it in another position, according to the electrode and the light sensor on the housing The position design of, as long as it can make the electrode and light sensor contact the skin, it is feasible.

Among them, when implemented as a light sensor, it can be installed on the wrist to obtain blood physiological information from the wrist, such as blood oxygen concentration, heart rate, etc., or it can also be installed on the forearm or upper arm. The above-mentioned blood physiological information can be obtained, or it can be set on the finger by combining with the finger-worn structure, especially the finger has always been the most commonly used position for obtaining blood physiological information. In addition, alternatively, it can also be set in reverse. Make the light sensor not touch the skin. At this time, the light sensor can be touched with the other hand, and blood physiological information can also be obtained. 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 face the torso and contact the torso, or it can be implemented to contact the hand towards the outside.

When 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, electromyographic signals, etc., or placed in front of the torso through a neck-worn structure , Through the two electrodes 120 contact the skin of the trunk at the same time to obtain the ECG signal.

In this way, whether electrodes or light sensors are used, when placed on the head, physiological signals of the head can be obtained, such as brain electrical signals, eye electrical signals, skin electrical signals, electromyographic signals, brain Blood flow, blood oxygen concentration, etc., when placed in front of the fingers, wrist, upper arm, forearm, and trunk, cardiovascular-related signals can be obtained, such as blood oxygen concentration, heart rate, ECG signals, etc. And other physiological information, for example, skin signals, and myoelectric signals.

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

In another conception, the physiological detection device in the form of earphones is selected.

Earphones have become an indispensable accessory in modern people’s daily life. Therefore, more and more physiological testing devices are implemented as ear-wearing forms, which not only allow users to use them naturally, but also make physiological testing more integrated into daily life. For example, ear wear is very suitable for sleep physiology testing, Cardiovascular testing, physiological feedback, neurophysiological feedback and other procedures.

Moreover, when implemented as an ear-wearing form, it can naturally provide earphone functions by combining sound components, which not only enhances the willingness to use, but also helps to provide physiological and neurophysiological feedback through sound, which is quite advantageous. Therefore, the ear-wearing form described in this article can be various forms of earphones available on the market, such as wired earphones or wireless earphones, as well as ear-canal earphones, earbud earphones, ear-hook earphones, neck-mounted earphones, headphone Wearing earphones, etc., are not limited. As long as they meet the following conditions, they are all within the scope of this case, and the way of providing sound can also be changed according to the different forms of earphones, such as wired Most of the sound of the earphone comes from the portable electronic device connected to it, while the wireless earphone may receive through a Bluetooth connection, or directly store recording files, MP3, etc. There are various possibilities.

Based on this, one of the embodiments of the multi-purpose physiological detection device provided by the present invention is, as shown in FIGS. 6A-6C, a form of dual ear wear, including a first ear wear structure 310 and a second ear wear In structure 312, the physiological signal capture circuit can be arranged in the first ear-wearing structure, or the second ear-wearing structure, or separately in two ear-wearing structures, or another housing for setting The circuit, as shown in Figure 6C, in this case, the other housing can also be used to set control buttons, etc., so there is no limitation. In addition, an electrode, an electrode 330 and an electrode 332, are provided on each of the two ear wear structures. In addition, the two ear-wearing structures are connected to each other through a connecting wire 314 to achieve electrical connection between the electrode 330, the electrode 332, and the physiological signal capture circuit.

Here, it should be noted that the setting method and position of the electrode will be different depending on the measurement signal. For example, the electrode can be placed in contact with the ear skin or not in contact with the ear skin. Position; In addition, in addition to additional electrodes on the surface of the ear-wearing structure, for example, electrode pads, it can also be implemented in other forms. For example, the surface of the ear-wearing structure can be directly implemented as electrodes, for example, using The method of coating the conductive layer, or directly using conductive materials (for example, conductive rubber, conductive silicone, etc.) to form the part, therefore, there is no limitation, as long as it is located on the surface of the ear-wearing structure, it can achieve the capture of electrophysiological signals. All belong to 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 as multiple small-area contact points in order to increase the achievement of contact. Probability, for example, can be implemented as electrodes with multiple needle-like structures, and, furthermore, can also be implemented as having elasticity, for example, using metal spring connectors (pogo pins) as electrodes to adapt to the undulations of the ear structure Changes and differences between different users increase contact stability. Among them, the electrode with multiple needle-like structures has different implementation options. For example, it can be welded on the circuit board by multiple conductive needle-like structures. It can also be an integrated conductive base and multiple conductive needle-like structures, no matter what the form is, there is no limitation, as long as it can provide multiple points of contact and form an electrical connection with the physiological signal capture circuit to obtain electrophysiological signals Yes, there is no limit.

In FIGS. 6A-6C, the electrode 330 is set at a position where it will contact the skin of the ear and/or the nearby area when the first ear wear structure is set on an ear. As for the electrode 332 on the second ear The setting position on the ear-wearing structure may vary depending on different usage scenarios. For example, FIGS. 6A and 6C show that the electrode 332 is located at a position that does not touch the skin near the ear, and FIG. 6B shows that the electrode 332 is located where it is accessible. The position of the ear skin.

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

In another mode of use, both the first ear-wearing structure and the second ear-wearing structure are removed. In this case, one option is to have both electrodes touch the chest, and the other option is to have the two electrodes touch the hands. Similarly, these two options can obtain chest pair The projection angle of the heart of the chest, and the projection angle of the heart of the hands.

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

Furthermore, it can also be implemented that each ear-wearing structure is provided with electrodes that contact the ears and electrodes on the exposed surface. In this way, only one hand (left or right hand) lifts and touches the ear-wearing structure. The exposed electrodes can be matched with the electrodes on the other side (right or left) that contact the ears to form a sampling loop. The advantage of this method is that the ear-wearing structure does not need to be removed from the ear to capture another ECG signal. Moreover, the left hand is raised to touch, the right hand is raised to touch, or the same time. Touch with two hands 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 contacts for obtaining the ECG signal are all achieved by electrodes on different ear-wearing structures, the inner and outer electrodes of the same ear-wearing structure can be further implemented as a continuous distribution In this way, the manufacturing complexity can be reduced and the manufacturing cost can be reduced.

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 method as shown in FIG. 7B can be used. Electrocardiographic signal measurement. In this case, since the exposed surface has a relatively large contact area, the action of removing the ear-wearing structure from the ear and contacting the upper limbs or torso can be achieved more easily. Therefore, there are various implementation possibilities in response to various use requirements, without limitation.

Here, it should be noted that although the above-mentioned embodiments mainly take the form of an ear shell as an example, it is not limited to this. The ear-wearing structure can be implemented in various forms, for example, an ear clip structure, Earhook structure, or combined form of earwear structure, for example, ear-in-ear shell plus ear-hook structure, or ear clip plus inner-ear shell structure, etc., as long as it can provide stable contact, it is a feasible choice, and, The two ear-wearing structures can also be implemented in different types, for example, one side can be implemented as an ear clip, and the other side can be implemented as an ear shell, so there is no limitation.

Since the two ear-wearing structures are connected by a connecting wire, when at least one ear-wearing structure is implemented to be removed from the ear for use, the contact position of the electrode becomes very variable, for example, the range of the connecting wire can be touched Therefore, it is possible to obtain the electrocardiogram of the respective positions of the twelve-lead electrocardiogram respectively. Therefore, compared with the large number of electrodes and the number of connecting wires required to obtain the twelve-lead electrocardiogram, this design is equivalent to a significant reduction The setting complexity and implementation threshold are quite helpful to achieve correct and detailed judgments of the heart in a simpler way.

Moreover, in addition to the above-mentioned use method of self-measurement by the user, based on the particularity of the structure, the design of the two ear-wearing structures with connecting wires can also be applied to obtain the ECG signals of others. For example, the first ear-wearing structure can be set on an ear of another person, so that the electrode is in contact with the ear and/or nearby skin, and then the electrode can be brought into contact with the torso of the other person by holding the second ear-wearing structure, or In this way, the upper limbs can obtain the ECG signals of others, which is very convenient. Here, the ear clip structure is a particularly suitable choice for the first ear 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 EEG signals. In any of the above configurations, as long as the two ear-wearing structures have electrodes that can contact the ears and/or nearby skin, they can be used to obtain EEG signals, so that the same device can provide ECG signals. There are two functions of capturing and EEG signal capture. Moreover, the ECG signal can also provide different projection angle options, which is very advantageous. Among them, when the EEG signal is captured, there is no specific contact position of the electrode. However, it is better to choose the electrode that touches the lower part of the auricle, for example, the tragus, the lower part of the tragus, the earlobe, the lower part of the concha wall, etc., as the reference electrode, which will be more conducive to obtaining Clear EEG signal.

Furthermore, in addition to electrodes, optical sensors can also be installed through the ear-worn structure. For example, it can be installed on one side or on 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, similarly, the light sensor will use the reflection method to obtain blood physiological information. In addition, when implemented as a hand contact electrode In the case of obtaining an ECG signal, it is also possible to obtain blood physiological information from the hand. For example, contact with the light sensor can be achieved while contacting the electrode. In this case, the heart can be obtained through the electrode at the same time. Through the electrical signal and the heart rate obtained through the sensor, the pulse transit time (PTT, Pulse Transit Time) can be obtained through the correlation between the two kinds of physiological information, and then the blood vessel hardness/elasticity and other information can be obtained. It is of further significance to infer blood pressure-related values through calculations.

On the other hand, when the light sensor is implemented in the ear and/or near the ear, it is suitable to be used to perform continuous detection, especially heart rate. For example, it can be used for heart rate monitoring during exercise or for long-term Patients who pay attention to heart activity, and through the multi-purpose design of this case, when there are special needs, such as sudden abnormal heartbeat or heart discomfort, the user can immediately touch the electrode by raising his hand or wearing the ear The structure touches the torso or hand, and records the real-time ECG signal, which is quite helpful to correctly judge the related heart problem.

Furthermore, according to another implementation concept of the present invention, a single ear-wearing structure can also achieve multi-purpose purposes. As shown in FIGS. 8A-8B, a single ear-wearing structure is provided with two electrodes 330 and 332.

In a preferred embodiment, as shown in FIG. 8A, when the ear-wearing structure is worn on the ear, the electrode 330 will contact the ear and/or the skin nearby. Therefore, it is only necessary to lift an upper limb to contact the exposed The electrode 332 on the surface can be used to measure the ECG signal. On the other hand, it is also removed from the ear, and the ECG signal can be obtained by touching different body parts, for example, the electrode 330 touches the holding hand and the electrode 332 touches the torso. .

In another preferred embodiment, as shown in FIG. 8B, the ear-wearing structure is implemented to be free When the ear is removed to obtain the ECG signal, there are many options for actual implementation. One option is that the ear wear structure can be held by the user with one hand and touched by the skin of the trunk. For measurement, for example, the two electrodes can be implemented to contact the torso at the same time, for example, the chest with a strong ECG signal to obtain the ECG signal of the torso, another option can be implemented as one electrode contacting the holding hand , The other contacts the torso to obtain the heart projection between the upper limbs and the torso, and the other option is to implement the two electrodes respectively contact the two hands to obtain the heart projection between the two upper limbs. Therefore, the usage can be changed according to different needs, which is quite convenient.

Furthermore, in order to facilitate holding by hand, the ear wear structure can be formed with an elongated member 316 as shown in FIG. 8B, and the electrodes are arranged on the elongated structure. In this way, while convenient for holding, 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 can be implemented as distributed on one surface, or distributed on multiple surfaces, or implemented as continuous distribution, etc., which are all feasible methods.

In addition, the two electrodes are not only arranged at the position where the ECG signal can be obtained when the ear-wearing structure is taken off, but also can be further implemented to be in contact with the ear and/or near the ear when the ear-wearing structure is installed on the ear. Skin contact, for example, tragus, earlobe, ear concha wall, ear concha bottom, the back of the auricle, the head around the auricle (temporal lobe area), etc., in this way, the brain can also be obtained while wearing the ear The electrical signal has more functions, and, as mentioned above, choosing the electrode that touches the lower half of the auricle as the reference electrode can be more conducive to obtaining a stable EEG signal.

Still further, it can also be implemented with a light sensor 340, for example, as shown in FIG. 8C, it is arranged 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. , In order to obtain blood physiological information, such as heart rate, blood oxygen concentration, etc., during the wearing of the ear, and then provide more diversified physiological information, and when the heart rate information can be obtained through the light sensor, it can be as before Said ground is used to perform continuous detection, for example, for heart rate monitoring during exercise, and/or for patients who need to pay attention to heart activity for a long time, so that when notified that the light sensor detects When it is abnormal, or when you feel that you have special needs, for example, When the heartbeat suddenly feels abnormal or the 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 structure of the inner ear shell as an example, it is not limited to this. The ear wearing structure can be implemented in various forms, such as an ear clip structure, an ear hook structure, or It is a combined type of ear-wearing structure, for example, an inner ear shell plus an ear hook structure, or an ear clip plus an inner ear shell structure, or the ear-wear structure can be combined with a supporting connection structure, etc., as long as it can provide a stable Contact is a viable option.

Furthermore, such a single ear structure can also be implemented with a connecting port for connecting an extension electrode. For example, another electrode can be provided in addition to the original two electrodes. In this way, different angles of the heart projection 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 to contact Upper limbs. On the other hand, it can also be implemented as an extended electrode to replace one of the original two electrodes. By expanding the distance between the two electrodes, the contact position of the electrode can be more variable. For example, The electrocardiogram of the positions of the twelve-lead poles is also helpful to obtain more detailed cardiac information. On the other hand, it can also be implemented as an extended electrode to obtain another 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, and then the electrode can be pulled out and placed in another One ear also touches the ear or the skin of the head near the ear to obtain EEG signals. Therefore, there are various possibilities and no limits.

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

In actual use, the extension electrode also has various possibilities. For example, an ear clip structure can be extended from the original ear wear structure to carry the extended electrode. In this case, Clamp the extended ear clip structure on the ear, and use the original ear-wearing structure to contact the trunk or upper limbs; alternatively, a finger-wearing structure can be extended to carry the extension electrode. In this case, the extension can be extended The finger-wearing structure is fixed on the fingers of an 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 extended electrode can be held by the hand, and To achieve contact, for example, touching the holding hand, or in order to touch other body parts, etc. 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 within the scope of this case.

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

Among them, the connection mode between the two ear-wearing structure and the head-wearing structure can be selected in different ways. For example, it can be connected by a connecting wire. Such a flexible cord connection method can make the setting of the head-wearing structure more free, or, It is implemented that the two are connected by 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 ear shell, so as to penetrate the mutual abutment between the ear shell and the auricle structure, for example, the plug is placed in the ear canal or is engaged with the auricle A better fixing effect can be obtained between the physiological concave-convex structure of the inner surface, etc., and this is not a limitation, and can be implemented in other forms, and the focus is to suit the actual implementation situation.

Here, in particular, the head-mounted structure is constructed to have different combinations with the head, as shown in Figures 9B-9C, the head-mounted structure can be set on the top of the head (Figure 9B), or set in the front Forehead, or set in the back of the brain (Figure 9C), the reason for this design is that, first of all, in terms of EEG signals, because the cerebral cortex is divided into many regions, and different cerebral cortex regions control different human activities. Therefore, when the electrodes are correspondingly set in different cerebral cortical regions In the position, the activity of each area can be obtained separately. For example, the lower part of the forehead corresponds to the frontal cerebral cortex, the lower part of the head corresponds to the parietal cerebral cortex, and the back of the head corresponds to the occipital cerebral cortex and ears. The upper part corresponds to the cerebral cortex area of the temporal lobe. Furthermore, in terms of eye activity, electrodes must be placed around the eyes to obtain ocular signals. In addition, in terms of skin and myoelectric signals, it is the frontal forehead. For a better setting position, according to this, it is only necessary to set the head-mounted structure at the position where the signal is to be obtained, which is quite convenient.

Wherein, the physiological sensing element can be implemented as at least two electrodes (not shown) to obtain electrophysiological signals on the head and/or ears. For example, one electrode can be provided on the head-mounted structure and another electrode can be provided on one of the ear-wearing structures. In this case, the electrode provided on the ear-wearing structure can be used as a reference electrode. When it is installed on the forehead, it can obtain EEG signals and ocular signals, and when it is installed on the top of the head and the back of the brain, it can obtain EEG signals, and depending on the position of the electrode on the head-mounted structure, the available brain The electrical signals also have different meanings. For example, even if they are worn on the top of the head or behind the head, if the electrodes are placed near the top of the ears, the electrical signals obtained will be the brain electrical signals in the temporal lobe area. On the other hand, if If the electrode is placed on the top of the head, the EEG signal of the parietal lobe will be obtained, or if the electrode is placed on the back of the head, the EEG signal of the occipital lobe will be obtained; or Both electrodes are set on the head-mounted structure. In this case, when the head-mounted structure is set on the forehead, the frontal lobe EEG signals and/or the temporal lobe EEG signals, ocular signals, and skin signals can be obtained Signal, and/or myoelectric signal, and when placed on the top of the head and back of the brain, it can obtain the occipital lobe EEG signal, parietal EEG signal, and/or temporal lobe EEG signal; An ear-wearing structure is provided with another electrode. As a result, since the two ear-wearing structures are placed on both sides of the head and matched with the electrodes on the head-wearing structure, the left brain and the left brain can be obtained separately. The activity of the right brain. Here, it should be noted that when it is used to obtain multiple electrophysiological signals, for example, when obtaining EEG signals and ocular signals at the same time, it can be implemented as having only two electrodes, and two types can be obtained from the same channel. The electrophysiological signal can also be implemented as more than two electrodes, for example, three or four, and two electrophysiological signals are obtained from two channels, because 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 installed on the head-mounted structure to obtain blood physiological information of the head, for example, it can be placed on the forehead, near the temples, and/or above the ears. The area obtains blood oxygen concentration, heart rate, brain blood flow changes, etc., or it can also be set on the ear-worn structure, which can also obtain blood physiological information such as blood oxygen concentration and heart rate.

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

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

Here, it should be noted that, since it may be necessary to set the electrodes on the top of the head, the back of the head, etc. with hairs, in addition to adopting the form of general dry electrodes, it is also preferable to implement the electrodes on the head-mounted structure. It is a needle-shaped form, for example, a single needle-shaped electrode or an electrode with multiple needle-shaped structures to facilitate the penetration of hair, wherein the electrode with multiple needle-shaped structures can have different implementation options, for example, It is formed by welding a plurality of conductive needle-like structures on the circuit board, or it can be an integrated conductive base and a plurality of conductive needle-like structures, no matter what the form is, there is no restriction, as long as it can provide multi-point contact and form The electrical connection with the physiological signal capture circuit is sufficient to obtain the electrophysiological signal; moreover, it is also preferable to implement the electrode to have elasticity, for example, a spring is arranged under the electrode, or a metal spring connector ( 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 replaceable, for example, originally a non-needle electrode is used to place it on the forehead. To the hairy position, replace with needle electrodes. In addition, the material of the electrode only needs to be a conductive material, for example, conductive metal, conductive rubber, conductive fiber, etc. are all feasible, so there is no certain limit. Moreover, preferably, when it is placed on the forehead or the back of the head, a strap can be further attached to the headwear structure, for example, connected to both ends of the headwear structure to achieve a better fixing effect.

In all the various embodiments described above, for example, finger wear, wrist wear, neck wear, head wear, For ear wear, clamping, etc., a motion sensing element can be added to the device, such as Accelerometer, G sensor, Gyroscope, Magnetic sensor ), etc., in order to obtain the user's body motion or movement at the same time, which can help determine whether the signal quality is poor due to body motion or movement when analyzing physiological signals. In addition, a temperature sensing element can also be added to the position where body temperature information can be obtained, which can help to further understand the actual physiological condition.

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

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

Wherein, the physiological signal capturing unit includes a physiological signal capturing circuit, which is housed in the housing 500, and has a first pair of electrical contact areas 510a, 510b on the lower surface 502 of the housing, and on the side of the housing There are a second pair of electrical contact areas 512a, 512b on the surfaces 506 and 508. Here, since the volume has been greatly reduced, the area of the electrical contact areas has been correspondingly reduced, for example, reduced to electrical contacts. Point form.

Furthermore, since the physiological information provided by different body parts may be different, the physiological signal capturing unit also includes at least one light sensor 522, as shown in the figure, disposed on the lower surface 502, It is 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 (Pulse Transit Time). , PTT), and then know the blood vessel hardness/elasticity and other information, but also can be further estimated to get the relevant blood pressure data.

Here, the reason for the distribution of the electrical contact parts in this way is to maximize the possibility of use. For example, one of the measurement options is to use the first pair of electrical contact areas To obtain the electromyographic signal and the skin signal, etc., or set it on the chest with strong electrocardiographic signal to obtain the electrocardiographic signal, another measurement option is that the second pair of electrical contact areas can be extended to touch more positions, and then obtain Other electrophysiological signals, such as brain electrical signals, eye electrical signals, skin electrical signals, myoelectric signals, electrocardiographic signals, etc. Therefore, through this design, it can adapt to different sampling requirements of various setting positions, which is quite advantageous.

Of course, as shown in FIG. 10A is only one of the configurations of the electrical contact area with the light sensor, and other configuration options are also possible. For example, as shown in FIG. 10B, another electrical contact area may be added to the upper surface 504. The contact area 514, alternatively, may also include only two electrical contact areas (similar to the situation shown in FIG. 3C), and may be arranged on the same surface as the light sensor, and/or on a different surface. Therefore, it may be practical The usage requirements vary, and there are no restrictions. In addition, other sensing elements can also be added, for example, a temperature sensing element, which is arranged on the housing where the body temperature can be obtained, and there is also no limitation.

When there is an electrical contact area 514 on the upper surface, it provides another option that can be directly exposed and contacted. This configuration is quite conducive to obtaining an ECG signal. For example, no matter where it is installed on the body, as long as the electrical When the contact area 514 is exposed, it can be easily contacted with a hand, and then any one of the electrical contact areas 510a, 510b, 512a, 512b is in contact with the skin of another part of the body (direct contact or extended And contact), forming a sampling loop of the ECG signal, is also a very advantageous implementation.

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

In addition, since the sampling position of each part is different and the setting conditions are also different, furthermore, the electrode can be set at the most appropriate sampling position through the wearing structure. In this case, it is better to A combination knot that can be combined with the shell is provided on the wearing structure Structure, for example, a accommodating groove, and an electrical contact portion corresponding to the 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 the electrode electrically connected to the electrical contact part is provided on the surface of the wearable structure, the electrical contact area on the housing can be electrically connected to the electrode on the wearable structure In this way, the wearable structure can be directly used to achieve the positioning and fixation of the electrode, which is quite convenient.

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

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

First of all, in the simplest case, the physiological signal capture unit is set on a finger of the user through a finger-worn structure. Here, the set position can be the fingertip, or the proximal or middle phalanx. There is no restriction on the knuckles, and there is no restriction on which finger, just provide the corresponding suitable finger-wearing structure, for example, as shown in Figure 11A, if the finger-clamp-type finger-wearing structure 600a is used, it can be set For the fingertips, if the ring-shaped finger-wearing structure is used, it can be placed on the knuckles. If the finger-clamping structure is used, it can be clipped on the fingertips or on the fingers as long as the shape is suitable. On the knots, the form of implementation 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 patches, patches, devil felt, etc., suitable for installation on any knuckles .

In addition, in terms of size, if it is to fit on the finger, it is better to minimize it. For example, the size of the housing is best implemented as a length less than 30 mm and a width less than 25 mm. Mm, and the thickness is less than 10 mm, so even if it is installed on the finger, it will not feel abrupt and burdensome.

When the physiological signal acquisition unit is set on the 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, etc. It is where the blood oxygen concentration is most commonly known.

Here, it should be noted that, as mentioned above, common blood oxygen concentration sensors on the market mainly adopt 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 allow light to penetrate the blood vessel for measurement. 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 arranged on the same side of the finger, and this method has the advantages of simpler structure and lower power consumption. Therefore, both methods have their own advantages and can be used.

Therefore, when a single housing is used, it is better to use reflection for measurement, that is, the light emitting element and the light receiving element are placed on the same side of the finger. On the other hand, if the wearable structure has physiological For sensing elements, for example, when the light emitting element is arranged on the housing and the light receiving element is extended to the wearable structure, the penetrating method can be used for measurement. Therefore, no matter where it is placed on the finger, it is all required There are no restrictions on the choice to use the transmission method or the reflection method for measurement.

Here, it should be noted that the finger-wearing structure used can be any form that can be fixed to the finger, for example, a ring structure, a finger sleeve structure, a finger clip structure, a surrounding structure, etc., without limitation. . On the other hand, the material can also have various choices. For example, it can be made of elastic materials, such as silicone, rubber, etc.; or, it can be made of flexible materials and fixed by winding, such as devil felt; or , You can also add a viscous substance to fix it by adhesion; or, you can also use a hard material with a finger ergonomic structure, for example, plastic formed in the shape of a clip, or plastic formed in the form of a ring , Metal, etc.; Or, different materials can be used in combination, for example, elastic materials can be coated with hard materials; it can even be implemented in a disposable form. Therefore, there are various possibilities without limitation.

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

For example, in one embodiment, the finger-wearing structure is implemented as a silicone fingertip cover (similar to the structure shown in FIG. 11A), and the housing can be simply directly embedded in the fingertip cover In the groove, it is not only convenient to manufacture, easy to fix and locate, but also comfortable to use; in another embodiment, a restoring elastic material can be used to make a finger-wearing structure, and the design of the structure can be opened The effect of fixing, and then fixing, as shown in Figures 11B-11C, the shell can be inserted into the elastic finger-wearing structure 600b; in another embodiment, the finger-wearing structure is implemented as an adhesive non-woven fabric , Can be used to surround the knuckles, and can also be used to stick to the fingertips. In another embodiment, the finger-wearing structure is implemented as 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-wearing structure is implemented as a ring-shaped finger-wearing structure 600c, and the combination of the shell and the ring can be made in various ways, for example, through clamping, plugging, magnetic attraction, etc.; In another embodiment, the finger-wearing structure is implemented by using elastic material inside, while the outside is covered with a hard material, such as a plastic shell. In this way, the elastic material can be used to achieve a finger curve to stabilize the physiological sensing element. At the same time, it can also provide a suitable and beautiful appearance. Even the exposed electrode can be provided with a hard material shell and connected to one of the electrical contact areas on the physiological signal capture unit. In this way, The ECG signal measurement will be possible.

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 such a design is adopted, not only is the volume compact, the structure installed on the finger is also quite simple, it is not easy to fall off, and it will not be hindered during sleep, but the blood oxygen concentration can be obtained very reliably. And heart rate and other information. Among them, blood oxygen concentration can be used to understand the breathing situation during sleep to provide relevant sleep Sleep Disordered Breathing (SDB) information, for example, sleep apnea (Obstructive Sleep Apnea, OSA), heart rate can be used to understand other physiological information during sleep, such as heart activity, and other physiological information derived from it Information, such as the time to fall asleep, and, further, if the housing is also provided with motion sensing elements, it can also detect the movement of the hands and the body, etc., and these are closely related to the quality of sleep, so , Quite advantageous.

Furthermore, if implemented during sleep, in order to allow the user to use it freely, the surrounding range of the finger-wearing structure can be extended to a part of the palm. For example, as shown in FIG. 11F, the surrounding finger-wearing structure 600d The part surrounding the palm under the thumb is increased. In this way, through a larger area of fixation, the user can feel more stable and does not affect sleep. Of course, the actual implementation of the finger-wearing structure is shown in Figure 11F. As an example, not as a limitation, as long as the structure that surrounds a part of the palm at the same time is within the scope of this case, there is no limitation.

On the other hand, in addition to the use of light sensors to obtain blood physiological information, electrodes can also be used to obtain electrophysiological signals. As mentioned above, due to the small size of the housing, the small contact area of the electrical contact area, and the short distance between the two electrical contact areas, in addition to the possibility of directly obtaining electromyographic signals and skin electrical signals, when you want to obtain other electrical In the case of physiological signals, or when the acquisition position of the myoelectric signal and/or the electrical skin signal cannot be directly achieved by the housing, the contact between the electrode and the skin can be achieved by further changing the finger-wearing structure.

In implementation, the finger-wearing structure is implemented to have a coupling structure for receiving the housing, and an electrode, which is located on a contactable surface, and is electrically connected to the electrical contact part located in the coupling structure, so that through the housing In combination with the bonding structure, the electrical contact area on the original shell can be extended to the electrode on the finger-mounted structure. Here, it should be noted that, depending on the actual measured physiological signals and the different positions to be set, the extension of the electrode can be implemented to extend only a single electrode, or it can be implemented as both electrodes extend outward. Way of implementation.

Among them, when used to obtain a skin signal or an electromyographic signal, only one electrode can be extended, To lengthen the distance between the electrodes, both electrodes can also be extended through the finger-worn structure to be set to different positions.

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

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

Furthermore, the housing can also be implemented to be combined with a head-mounted structure, as shown in FIG. 12A, to be set on the user's head. As is well-known, the head can obtain many physiological signals, for example, it can use electrodes to obtain EEG signals, ocular signals, skin signals, myoelectric signals, etc., and can use light sensors to obtain brain blood flow. Changes, blood oxygen concentration, heart rate, etc., among which EEG signals, ocular signals, and changes in brain blood flow are physiological information that can only be obtained from the head, so they are very important locations for physiological monitoring.

In this case, there are certain restrictions on the location of electrodes for obtaining EEG signals. For example, electrodes are generally set up in accordance with the international 10-20 system (international 10-20 system). The electrodes also need to be arranged around the eyes. Therefore, it is suitable to use the electrode extension design as described above to set the electrodes to the desired position through the head-mounted structure.

In implementation, similarly, as shown in FIG. 12B, the headwear structure 700 is implemented to have a coupling structure 710 for receiving the housing, and in particular, the coupling structure has a corresponding electrical The electrical contact portions of the contact area 510b and the electrical contact area 512b are combined to achieve electrical contact at the same time, and then are electrically connected to each other through a connection line arranged along the head-mounted structure The extension electrode 740 is arranged on the head-mounted structure. In this way, even if the volume of the housing according to the present case is very small, it is very easy to obtain EEG signals.

Moreover, as long as the form of the headwear structure is changed, for example, the shape of the headwear is changed, the electrodes can reach any head area and obtain the EEG signals of the cerebral cortex area at the relative position, for example, when set in the front In the frontal time, the EEG signal in the frontal lobe area can be obtained. When it is installed on the top of the head, it can obtain the EEG signal in the parietal lobe area. When it is installed on both sides of the head and near the top of the ears, it can obtain the brain electrical signals in the temporal lobe area. Electrical signals, and when placed at the back of the head, EEG signals in the occipital lobe area can be obtained. As we know, different cerebral cortex areas are in charge of different functions of the human body, therefore, the monitoring of each cerebral cortex area has its meaning.

As for the form of the headwear structure, there are different options depending on the position where you want to get the signal. For example, if you want to set it on the forehead, you can simply use the form of patches, stickers, and glue to reduce the burden. In the form of straps or a head frame with clamping force, if you want to set it on the top of the head, you can use a head frame, hat, etc., if you want to set it behind the head, you can use a strap, hat, head frame, etc. ; In addition, if you want to obtain ocular signals, you can set it on the forehead or extend it down to around the eyes. Therefore, there are no restrictions and can be changed according to actual needs.

Among them, a special type of head-mounted structure is the glasses structure. Generally, when the glasses structure is worn on the head, the contact positions include the bridge of the nose and the upper ears, and in some cases, it also touches the surrounding area of the eyes. Therefore, this configuration is very suitable for obtaining ocular signals. EEG signals in the frontal lobe area, and EEG signals in the temporal lobe area. 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 combined with the glasses structure.

Here, it should be noted that, depending on the actual measured physiological signal and the desired location, the extension of the electrical contact area can be implemented as a single extension, or both electrical contact areas can extend outward. For example, when the head-mounted structure is set on the forehead, or when the head-mounted structure is implemented as a spectacle structure, an electrical contact area on the housing can be directly used, and only one electrical contact area can be extended. Therefore, there is no restriction .

And this setting is also very suitable for use during sleep. For example, the most important basis for judging the sleep stage is the EEG signal, for example, rapid eye movement (REM, Rapid Eye Movement), deep sleep, light sleep, wakefulness, etc. In addition, the myoelectric signal and the ocular signal are also used to determine whether it is in the rapid eye movement period. These are the physiological information commonly used to determine the quality of sleep. Furthermore, the blood oxygen concentration obtained by the light sensor can be used In order to obtain the breathing situation during sleep, for example, when sleep apnea occurs, it is usually accompanied by a decrease in blood oxygen concentration. Therefore, you can determine whether sleep apnea occurs by observing the blood oxygen concentration. In addition, the obtained heart rate can be understood The physiological state during sleep, such as the state of the autonomic nervous system, the state of heart activity, whether there is arrhythmia, etc., can also be used to determine the time to fall asleep (sleep onset), etc. In addition, if the housing is also equipped with motion sensing The components can also detect the user’s movements such as turning over. Therefore, almost all the physiological signals obtained by the general sleep examination are included. Moreover, it can be completed only by a small and exquisite shell with a head-mounted structure. Complicated wiring is quite advantageous.

Furthermore, the shell can also be implemented to be combined with a neck wear structure 800. As shown in Figures 13A-13B, through the neck-wearing structure, the shell can be set in front of a user's torso, and when set in front of the torso, it is very suitable for obtaining ECG signals. The volume of the housing is small and the distance between the two electrical contact areas is very short. Therefore, the electrical contact area can be extended through the combination 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 to expand the distance between the electrodes, which is suitable for obtaining ECG signals in front of the torso. In this case Next, the user can easily obtain the ECG signal by simply pressing the combination of the housing and the combination structure at the front of the drive.

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

In addition, the shell can also be implemented in combination with an ear-wearing structure. Since the volume of the casing is very small, when it is placed on the ear, there is little difference in volume from the current common earphones on the market, which not only causes no burden, but is also not obtrusive.

At the position on and/or near the ear, blood oxygen concentration, pulse signal, heart rate, etc. can be obtained through light sensors, and brain electrical signals, electromyographic signals, skin electrical signals, ECG signals, etc. can be obtained through electrodes. There are also various options. Among them, the light sensor only needs to be in contact with the ear or the skin near the ear. EEG signals, myoelectric signals, skin signals, etc. can contact the ears and/or the skin near the ears through two electrodes. As for obtaining the ECG signal, it is preferably implemented as one electrode contacting the ear or the skin near the ear, and the other electrode extending to the exposed surface for contact by an upper limb.

As for the form of the ear wear structure, there are also various possibilities, whether it is the form of the ear shell, the ear hook, or the ear clip, all possible methods, and the materials used can also be corresponding to different forms The settings of the electrodes and light sensors will also be different. For example, when implemented in the form of an ear shell, it can be implemented to cover the shell with an elastic material, such as silicone, so as to adapt to the depressions and protrusions on the inner surface of the auricle. In this case, the electrode can be It is directly exposed from the broken hole of the covering material, and the extended form as described above can also be used to achieve contact with the skin; when implemented as an earhook form, there will be a pendant hanging above the auricle, so it is increased 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 position of the housing, it can be set in front of the auricle, or The rear of the auricle is optional; 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 clipped part of the ear, such as the earlobe, 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 is only necessary to ensure that it is exposed, can be contacted and fixed on the skin, and therefore, it is a feasible way without limitation.

Furthermore, the shell can also be implemented to be combined with a wrist-worn structure 900, as shown in the figure Shown in 14A-14B. In the vicinity of the wrist, blood physiological signals such as pulse signal, heart rate, and blood oxygen concentration can be obtained through light sensors, and electrophysiological signals such as myoelectric signal, skin electrical signal, and electrocardiographic signal can be obtained through electrodes. Among them, The acquisition of electromyographic signals and skin signals requires two electrodes to contact the same part of the skin at the same time. In addition, the acquisition of electrocardiographic signals can be implemented as one electrode touching the skin near the wrist and the other electrode extending to the exposed surface. For contact with other body parts, for example, another upper limb, trunk, etc.

Here, due to the small volume of the casing, the shape of the wrist-worn structure will become very free, which can be in the form of a bracelet, a watch, or a strap. In this way, the user can follow the actual situation. Use habits and choose the wrist-worn structure you want.

The configuration of electrodes and light sensors is similar to the above. Wherein, 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 to directly expose the electrode 514 on the housing to achieve contact. As shown in FIG. 14A, it can also be worn on the wrist. The structurally extending electrode 910, as shown in FIG. 14B, is not limited.

Here, it should be noted that the above-mentioned wearing structure is for illustration only, and not as a limitation. The wearing structure that can be fitted with the casing according to the present invention is not limited, as long as it can be combined with the casing and attached to the casing. The wearing structure of the human body surface, such as arm wearing structure, chest strap, legging strap, patch, etc., are all within the scope of application of this case and there is no limitation.

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

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

Furthermore, when the above-mentioned device is used for detection during sleep, especially when implemented as a finger-wearing form, in addition to the above-mentioned case where the wearing structure is detachable from the housing, it can also be implemented as an integral finger-wearing structure 600e, such as As shown in Fig. 15, a shell that is clamped on the fingertip or a finger-wearing structure that is directly formed to be fixed through a finger ring is a feasible way. There is no limitation, and it only needs to be fixed on the finger.

During sleep, there are several physiological signals that can be measured on the finger and reflect the physiological state of sleep. For example, the blood oxygen concentration can be used to know whether there is hypopnea, such as shallow breathing, respiratory arrest, etc. It is because when there is low breathing, the amount of oxygen in the blood will decrease. Therefore, the changes in breathing during sleep can be learned by observing changes in blood oxygen concentration; in addition, heart rate can be used to assist in observing the physiological state during sleep, such as , The state of the autonomic nervous system, the state of heart activity, whether there is arrhythmia, etc., can also be used to determine the time to fall asleep (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-sized device worn on the finger, combining the above information can also obtain a lot of information about the physiological state of sleep, such as sleep quality, which is especially suitable for understanding whether there is sleep breathing disorder (Sleep Disordered Breathing, SDB), for example, Obstructive Sleep Apnea (OSA).

On the other hand, after knowing one's own sleep situation, if it can provide a program to help sleep and/or help relieve pressure at the same time, it will be a more complete solution for the user.

In recent years, more and more studies have shown that the human body can influence the body's operating system through self-consciousness regulation to achieve the effect of improving physical and mental health, for example, triggering a relaxation response in the body. The so-called relaxation response can be said to be a physical response that complements the fight-or-flight response. Generally speaking, the relaxation response occurs when the body no longer perceives danger. At this time, the autonomic nerves The activity of sympathetic nerves in the system will decrease, and this response can be achieved through meditation, breath training, biofeedback, and progressive muscle relaxation. It is triggered by relaxation), yoga and other methods in the body, and 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 process, 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 will be monitored through instruments, and information will be quickly and accurately fed back to the subject. Since this information is related to the desired physiological change, it is subject to After the examinee obtains the information, he can adjust his/her self-consciousness accordingly to strengthen the required physiological response and/or improve his/her physiological state.

And through the configuration of electrodes and/or other physiological sensing components in the physiological detection device described above, the physiological signals that can be obtained, such as brain electrical signals, electromyographic signals, skin electrical signals, heart rate, blood flow, skin temperature, etc. A physiological signal often used in physiological feedback procedures.

Among them, when the alpha wave is dominant in the brain wave, it means the human body is in a relaxed and awake state, when the beta wave is dominant, it means the human body is awake and tense, and when the θ wave is dominant, it means the human body is in a relaxed state with interrupted consciousness. Therefore, the physiological and consciousness state of the human body can be learned by observing the changes in brain waves; the myoelectric signal represents the tension of the human muscles, and the muscle tension is also related to the activity of the autonomic nervous system. The degree of tension; the electrical skin activity is related to the activity of the sweat glands, and the secretion of the sweat glands is only affected by the sympathetic nerves, and when the activity of the sympathetic nerves increases, the activity of the sweat glands increases, so the increase in the activity of the sympathetic nerves can be known by measuring the electrical skin activity 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; heart rate is regulated by both sympathetic nerves and parasympathetic nerves, and when sympathetic nerve activity increases, The heart rate becomes faster. When the parasympathetic nerve activity increases, the heart rate becomes slower. Therefore, the activity growth and decline between the two can be known by observing the heart rate sequence; in addition, because the blood vessels that transmit to the skin of the extremities are only affected by the sympathetic nerves, and When the sympathetic nerve activity decreases, the vasoconstriction decreases, the tube diameter increases, the blood flow increases, and the skin surface temperature rises. Therefore, the activity of the sympathetic nerve relative to the parasympathetic nerve can also be inferred by measuring the skin temperature of the limbs. Increase or decrease in nature, for example, measuring temperature through a temperature sensing element.

And as is well known, sympathetic nerves and parasympathetic nerves are the autonomic nervous system of the human body. Therefore, by obtaining these physiological information, one can know the physiological information related to the autonomic nervous system of the human body. Therefore, the physiological information, whether it is electrophysiological information or Blood physiological information or body temperature information are suitable for physiological feedback procedures. For example, physiological feedback can be performed before going to bed to achieve a physiological state conducive to sleep. For example, physiological feedback can be used to increase brain waves The proportion of alpha waves can induce sleep. In addition, physiological feedback can also be provided during leisure time. For example, increasing the activity of parasympathetic nerves through physiological feedback can 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 the relevant acquired physiological signals to the user through a notification message, so that the user can instantly know the physiological changes, and then Achieve the settings required to perform the physiological feedback program.

For example, the information providing unit can be directly set on the physiological detection device to provide information through various notification methods that can be sensed by sight, hearing, and/or touch, for example, using flashing lights, patterns, numerical changes, and other visual capabilities. Sensing methods, auditory perceptible methods such as sound and voice, and/or tactile perceptible methods such as vibration and temperature change, can be achieved by setting heating elements, vibrating elements, sound 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 choose the physiological signal as the basis of the physiological feedback based on the difference in the purpose of the feedback or the difference in the usage habits. For example, as long as the finger-wearing structure is selected, The body temperature information, blood physiological information, and/or skin electrical information can be obtained from the finger, and relaxing physiological feedback can be easily performed, which is very convenient.

Furthermore, when the wearable physiological detection device according to the present invention is used, only the wearing structure is simply placed, for example, wearing a ring, wearing glasses, wearing headphones, wearing a bracelet, etc., is equivalent to completing the 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 then the physiological feedback can be carried out. It is quite convenient, and because of such a simple and convenient setting, there is almost no time in use. , Location restrictions, for example For example, during commuting, before going to bed, etc., are the times and places where physiological feedback can be performed, which is quite helpful to enhance the user's willingness.

In contrast, the traditional physiological detection devices used for physiological feedback often have complicated wiring. For example, there is usually a machine installed on the desk next to the user. On the body, for example, if the 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 respectively connected to the user’s two fingers. For body temperature detection, it also needs to be wired to the position where the body temperature is to be obtained. In this case, the user is tied to the table, which not only restricts the place of use, but also restricts 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, instructions, etc. related to the user during other wearing periods. For example, it can be used when the detected physiological signals meet preset conditions. For example, if the heartbeat is fast, arrhythmia occurs, the blood oxygen concentration is too low, etc., the user is reminded through various methods such as sound, vibration, flashing, etc. Therefore, 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 real-time user information during the physiological feedback period, for example, using real-time wireless transmission with a smart phone, for example, through the mobile phone Execute the application (APP) to communicate with the physiological detection device worn on the body. The above-mentioned various methods, whether visual, auditory, or tactile perceptible, can be achieved by using a mobile phone, which not only reduces the burden on the hands, but also Also, because various portable electronic devices such as smart phones and tablets have been fully integrated into the daily lives of ordinary users, they are also quite 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 the detection results. In this case, it can be It can be implemented as real-time wireless transmission, or after the physiological monitoring is over, there are no restrictions. Therefore, the housing can also be equipped with a memory to store the acquired physiological signals and download them to an external device after the monitoring is over 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 will be implemented in the devices in all the previous embodiments of this case, that is, any device mentioned so far in this article can be further equipped 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 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.

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