Detailed ways

First, the wrist and neck were chosen as locations for the setup. The main reasons for choosing these two locations are, firstly, both are locations where general users often install physiological detection devices, and secondly, both are frequently used locations where ECG signals can be obtained.

The wrist-worn ECG capture device is a known implementation, and the neck-worn form is also a known implementation, wherein the wrist-worn ECG capture device obtains the ECG by touching the two upper limbs, Since the device can be naturally placed on the wrist, the ECG signal can be obtained by pressing the other hand when measurement is required, which is convenient to use. However, there are also problems to be overcome in hand-held operation. For example, hand-held The stability of the internal operation is poor, prone to noise (artifact), and also prone to EMG interference. Moreover, users with a thinner body, such as women, are also prone to weaker signals and difficult to measure.

As for the neck-worn ECG capture device, it is installed in front of the torso through the neck-worn structure. Since the contact position of the electrodes is very close to the heart, the obtained ECG signal will be clearer, and therefore , can be less affected by the EMG signal. In addition, in this way, the device can also be hidden in the clothes. It is also a very convenient ECG signal capture device.

Therefore, the two forms have their own advantages, so for the wearable ECG signal acquisition, it will be very helpful for users if a device that can be used in both forms can be provided.

Moreover, according to the relative position to the heart, when the two electrodes touch the chest, or touch the chest and an upper limb, or respectively touch two upper limbs, ECG information at different projection angles of the heart can be obtained, which is useful for detailed judgment of the overall condition of the heart. great help.

In the first embodiment of the present utility model, such a concept is achieved through the design of electrode positions and structures. As shown in Figures 1A-1B, the multi-physiological detection device according to the present invention has two electrodes disposed on the surface of the housing 100, wherein the housing is implemented in the shape of a flat cuboid at both ends of the shortest axis It has an upper surface 102 and a lower surface 101, and each has an end in the long axis direction, a first end 106 and a second end 108, and two electrodes, a first electrode 110 and a second electrode 112 , are respectively arranged at the first end portion and the second end portion.

Here, it needs to be explained that, generally, when picking up electrophysiological signals, signal picking electrodes and grounding electrodes are usually set up. Among them, the signal picking electrodes are used to obtain electrophysiological signals, and the function of grounding electrodes is to remove Background noise, and all the electrodes described in this article belong to the signal extraction electrodes, for example, the first electrode and the second electrode mentioned above are the first signal extraction electrodes and the second signal extraction electrodes, but to avoid The wording is too lengthy. In the following description, "electrode" is used to represent "signal acquisition electrode". As for the setting of the grounding electrode, it can be selectively set according to actual needs, and will not be described in this article.

In addition, as shown in FIG. 1C, the multiple physiological detection device also includes a physiological signal acquisition circuit 113, which is mainly disposed in the housing 100 and electrically connected to the first electrode 110 and the second electrode 112, so as to Physiological signals are obtained by contacting the first electrode and the second electrode with the human body. Here, it should be noted that the physiological signal acquisition circuit includes all necessary circuits and components for obtaining physiological signals, for example, Processors, analog signal processors, analog-to-digital converters, filters, memory, batteries, etc., are well known to those skilled in the art, so they will not be described in detail; in addition, if there is a need for wireless transmission, for example, to When the obtained physiological signal is transmitted to an external device, a wireless transmission module may also be included, or the memory may also be implemented in a removable form. Therefore, different circuits, components, and/or modules can be set according to actual needs, all of which belong to the scope of the present utility model without certain restrictions; in addition, the electrodes described here are commonly known sensory The conductive material that detects the spontaneous potential difference of the human body, such as metal, conductive fiber, conductive rubber, conductive silica gel, etc., so in the following description, only the installation position, installation method, shape, etc. of the electrodes will be described.

The feature of this embodiment of the utility model is that, through the special distribution design of the two electrodes on both sides of the casing, the multiple physiological detection device according to the utility model only needs to replace different wearing structures, and it can be adapted Get ECG signals at the wrist, or at the front of the torso.

Wherein, the first electrodes 110 are distributed on the five surfaces of the first end portion 106, and the second electrodes 112 are distributed on the five surfaces of the second end portion 108, especially, the two ends opposite to each other On one side surface, the whole is covered with electrodes, and in the remaining four surfaces, there is no special limitation. For example, as shown in FIG. 1A, the same width can be covered, or, different width, or different shapes, etc., as long as the electrodes are distributed on the four surfaces.

In addition, in addition to the implementation form in which the four surfaces around the long axis of the cuboid are formed into a single arc surface as shown in Figure 1A, the flat cuboid can also have other implementation forms, for example, Figure 2C and Figure 2D show two other possibilities , Therefore, there is no limitation, as long as the design conforms to the flat cuboid, it all belongs to the scope of the present case.

And just through above-mentioned special structure and shape design, make when choosing the setting position of body and when combining with wearing structure, according to the device of the present utility model, can have various implementation possibilities.

First, as shown in FIG. 2A, when the housing 100 is combined with a neck-wearing structure 200, as long as it is confirmed that one of the upper surface or the lower surface is facing the direction of the torso B, the first electrode 110 and the second electrode 112 will be It can naturally face the torso at the same time. Figure 2A shows an example where the lower surface 101 faces the torso. Afterwards, when there is a need for measurement, the user only needs to press the shell with his hand, as shown in Figure 2B, to achieve the first electrode And the contact between the second electrode and the skin of the trunk to obtain the ECG signal, or, if the user is wearing tights, as long as the housing is placed inside the tights, the ECG can even be obtained without hand pressing No. Here, it should be noted that although Fig. 2A-2B shows the case where the casing is placed between the clothes 400 and the torso B for measurement, this is not a limitation, as long as the casing can be made close to the torso and the electrodes and the skin can be reached. For example, the user may not wear a coat, or put his hand into the clothes to press, or, it is also possible that the length of the neck wearing structure is short so that the shell is exposed outside the clothes. Therefore, there are various Possibly, without limitation.

At this time, it will be very suitable to use wireless transmission to confirm the electrode contact status by an external device, start the acquisition of ECG signals, and display the operation process and/or ECG-related information (such as ECG, heartbeat, etc.), for example, Interfaces on smart phones, smart watches, tablet computers, or other portable electronic devices, such as application programs, can be used for control and display, which is quite convenient to use.

For example, when there is a detection need, the user only needs to open the application program on the mobile phone, and then use one hand to press the shell to make the electrodes on the body come into contact with the skin in front of the torso, and at the same time start the ECG signal through the application program. In this way, you can receive real-time ECG-related information on the screen of your mobile phone, such as heart rate, ECG, etc. Of course, it can also be set to automatically start ECG measurement, for example, when the application is opened In the state, as long as the contact between the electrodes and the skin is detected, the acquisition of the ECG signal will be automatically started, or it can also be implemented as when a stable ECG signal is detected, for example, there are several stable and reasonable The signal acquisition will only start when there is an ECG signal or a stable DC baseline, or it can also be set so that the contact stability between the electrode and the skin needs to meet the preset conditions before it will start automatically, for example, the impedance value is high enough, The pressure on the surface of the electrode is high enough, etc., which are all optional preset conditions without limitation.

Therefore, in the case that the neck-worn form detection device has the wireless transmission function, it provides a very convenient operation process, that is, the user only needs to press the housing with one hand to achieve the contact of the two electrodes, while the other hand is empty. One hand can operate an external device connected to the neck-worn detection device, for example, a mobile phone, so the operation is quite easy and advantageous.

During the measurement period, for example, 30 seconds, 1 minute, or other time lengths set according to requirements, various relevant information such as ECG waveform, heart rate, and electrode contact status can be displayed in real time on the mobile phone, so that users can clearly Know the measurement situation at any time, for example, whether the electrode is in good contact with the skin, whether the hand shakes, etc., and the measurement can also be interrupted at any time by operating the application program.

After the measurement, the obtained ECG-related information can be directly recorded and stored in the mobile phone, or can be stored in the detection device at the same time, or the user can decide whether to record the measurement, for example, when When there are too many unstable situations during the measurement, the user can choose to give up saving the measurement and perform the measurement again, so it can be different according to actual needs.

Furthermore, when the ECG signal can be obtained continuously, for example, when the hand is pressed for a long time on the casing arranged in front of the torso, other physiological information can be further obtained through the obtained ECG signal, for example, The time series of heartbeat intervals can be obtained according to the electrocardiogram for HRV (Heart Rate Variability, heart rate variability) analysis, and the activity of the autonomic nerve can be known. Arrhythmia) information, and then know the breathing changes used, and provide the information to the user through an external device, such as a mobile phone, to guide the user to carry out breathing training that helps to improve the balance of the autonomic nerve.

As for how to combine the neck wearing structure and the housing, there are various possibilities. The neck wearing structure will have a combination structure 202 for combining with the housing, one implementation may be, as shown in Figure 2D, the combination structure and the housing are combined at a single point; another implementation is possible Yes, as shown in Figure 2C, the connection between the combination structure and the shell has directionality, and since the flat cuboid has directionality, this method can make the shell appear naturally when it is placed in front of the torso. The surface 102 or the lower surface 101 faces the direction of the torso, which can make it more convenient to use; another implementation possibility is that the combination structure is implemented as a frame, and combined with the housing, in this case, the frame can be simply The frame is implemented to only partially cover the shell and expose the first electrode and the second electrode to contact the part of the torso, or the frame can also be implemented to cover the shell as a whole, and the first electrode 110 on the original shell surface And the second electrode 112 extends to the surface of the frame contacting the torso by means of electrical connection. In this way, it increases the possibility that the contact position of the electrode can be changed accordingly. In addition, the combination structure can be further implemented in a removable form. For example, the above-mentioned different types of combination structures can be replaced with each other to achieve different combinations with the housing, etc., which will further increase the variability and adaptability. sex. Therefore, without limitation, various forms may be implemented according to needs.

On the other hand, as shown in FIG. 3A , the casing can also be implemented to be combined with a wrist-worn structure 500. At this time, it must be confirmed that the first electrode 110 or the second electrode 112 must achieve contact with the skin of the wrist. Figure 3A shows an example where the lower surface 101 faces the wrist W, and then, since both the first electrode 110 and the second electrode 112 extend to the upper surface 102, when there is a detection requirement, the user only needs to Need to make the electrodes on the upper surface touch the skin of another part of the body, for example, the other hand touches the electrodes, or the wrist of the wearing device moves so that the electrodes touch the skin of the torso, or another upper limb, or other limbs. Obtain the ECG signal, so it is an optional sampling method without limitation.

Here, it should be noted that, in general cognition, the same electrode cannot touch two parts of the body at the same time when measuring ECG signals. Touching the wrist at the same time, as long as at least one of the electrodes extending to the upper surface touches another part of the body, such as the other hand, a potential difference can be formed to drive the physiological signal acquisition circuit to obtain ECG signals. Therefore, even if the same electrode simultaneously Contacting two parts of the body can also obtain ECG signals smoothly.

This is also the theoretical and experimental basis for this case to be able to successfully obtain ECG signals at both setting positions under the condition of adopting the aforementioned electrode position design, and it is also different from the prior art and general cognition. Moreover, based on such experimental findings, it is possible to have a design that is closer to the use requirements in actual implementation.

In addition, according to such experimental results, other forms of electrode arrangement can also be used. As shown in FIG. 3B, the two electrodes can be implemented to surround the shell for a week. In this way, as long as the shell is surrounded by the two electrodes Any surface that touches the torso or wrist can be used to capture ECG signals, which will further reduce the restrictions on the direction of use and provide more convenient use options.

Here, it should also be noted that in addition to being implemented as a wrist-worn structure, it can also be implemented as an arm-worn structure. For example, it can be installed on the forearm or upper arm, and can also obtain ECG signals without limitation.

In this way, even the same device can be installed on different body parts as long as it is combined with different wearing structures, and most importantly, no matter where it is installed, it only needs to use the existing common operation methods, without It is very convenient to obtain ECG signals naturally for any skills that require special learning.

In addition, the additional benefit brought by such a design is that when different wearing structures are used and placed in different body positions, ECGs with different leads can be obtained. For example, two electrodes can be obtained when the neck is worn. The heart projection formed by touching the trunk at the same time. In addition, when the wrist is worn, different heart projections can be obtained according to the different contact positions of the electrodes. For example, when the exposed electrodes are touched by the other hand, two upper limbs can be obtained. The cardiac projection formed, or, when the wrist wearing the wrist-worn structure is close to the torso and the exposed electrodes touch the torso, the cardiac projection formed by the torso and upper limbs can be obtained. At this time, because the measurement position is closer to the heart, Therefore, better signal quality can be obtained, for example, better signal-to-noise ratio (S/N ratio), so it can be changed according to different needs, and it is more helpful to accurately judge the condition of the heart.

In addition to the embodiment shown in FIG. 1 , the configuration of the electrodes can also have different implementation options. As shown in Figure 4A, the electrodes may be implemented as two separate parts, electrodes 110a and 110b, electrodes 112a and 112b, but here, in particular, the electrodes 110a, 110b are implemented in parallel with each other, and the electrodes 112a, 112b are Implemented in parallel with each other, that is, from the perspective of the circuit, the electrodes 110a and 110b will be regarded as the same electrode, and the electrodes 112a and 112b will also be regarded as the same electrode, which is equivalent to the situation in Figure 1, is another viable option.

Alternatively, another implementation may be to provide multiple sampling channels using an electrode configuration as shown in Figure 4A. For example, it can be implemented to obtain ECG signals by using the sampling channels of the electrodes 110b and 112b or the sampling channels of the electrodes 110b and 112b when it is placed on the front of the torso, and when it is placed on the wrist, use the electrode 110a and the sampling channel formed by at least any one of the electrodes 112a and at least one of the electrodes 110b and 112b to obtain ECG signals. Therefore, there is no limit.

Alternatively, instead of using the electrode sharing method, two sets of electrodes can be set separately to obtain ECG signals when the neck-worn structure is used and when the wrist-worn structure is set, that is, sampling at two positions The circuits are independent of each other, which is also a feasible way, so as long as the ECG signals can be obtained at two positions, there is no limit.

On the other hand, Fig. 4B shows another possible implementation of the wrist-worn structure. In FIG. 4B , the wrist-worn structure 500 is implemented to cover the upper surface of the casing, and when combined, one of the first electrode and the second electrode will contact the inside of the wrist-worn structure 500 An electrical contact portion (not shown), and through the electrical contact portion, the electrodes on the original housing can be electrically connected to a third electrode 114 on the outer surface of the wrist-worn structure 500, so that the The third electrode is equivalent to an extension of one of the electrodes on the casing, which can be touched by the user, for example, the other hand (as shown in Figure 4C), or the torso or other body parts, so as to communicate with the unextended The other electrodes together form a sampling loop to obtain ECG signals. In addition, the form shown in Figure 3B and Figure 4A, and the above-mentioned embodiment using two sets of independent sampling circuits, can also adopt the wrist-worn structure as shown in Figure 4B, so that one of the electrodes extends to the surface of the wrist-worn structure, no limit.

When using the wrist-worn structure as shown in Figure 4B, further, the configuration of the electrodes can also be implemented such that neither the first electrode nor the second electrode extends to the upper surface of the housing, as long as the wrist-worn structure connects one of the electrodes It is also feasible to extend to the surface of the wrist-worn structure, and the advantage brought by such a change is that, for example, if the shell is composed of two parts, it can be implemented that the electrodes are only placed in it In this way, the manufacturing process can be simplified and cost savings can be achieved.

Therefore, the location and structure of the electrodes can be changed according to various conditions such as actual needs and manufacturing processes, without limitation. For example, it is also possible that only one of the first electrode and the second electrode extends upward to the upper surface, or the third electrode is provided on the upper surface in parallel, as long as it meets the requirements of use, there is no certain implementation However, in particular, in the above-mentioned embodiment, another use option is further provided, as shown in FIG. 4D , the first electrode 110 and the second electrode 112 are arranged on the lower surface 101, And the third electrode 114 is set on the upper surface 102, so that when it is placed in front of the torso through the neck-worn structure, the first electrode 110 and the second electrode 112 can be used to contact the torso to obtain ECG signals , and when it is installed on the wrist, there are two possible uses, one is to make the lower surface 101 face the wrist, and let the first electrode and the second electrode contact the wrist, and then make the third electrode contact Another part is to make the upper surface 102 face the wrist so that the third electrode contacts the wrist, and then make the first electrode and/or the second electrode contact other parts of the body to obtain the ECG signal. Obtaining ECG signals, that is, using different sampling loops for signal acquisition when it is set at different locations, therefore, there are various implementation possibilities without limitation.

Still further, a light sensor may also be included, which is arranged on the surface of the casing to obtain blood physiological information from the user, such as blood oxygen concentration, heart rate, blood flow and other information. Generally speaking, the finger is the most commonly used position to obtain blood oxygen and heart rate. However, as long as the position where blood vessels pass through, the optical sensor can be used to obtain blood physiological information. Therefore, the position of the optical sensor can be adjusted according to the needs. Different, without limitation, for example, as shown in FIGS. 1A-1B , the light sensor 401 can be implemented to be disposed on the lower surface 101, so as to contact the hand together with the electrodes when the housing is disposed on the hand or torso. , or the torso; or, the optical sensor can also be arranged on the exposed surface of the housing when it is placed on the hand or the torso, so as to obtain blood physiological information from another part of the body, such as the other hand. unlimited.

In the case of light sensors, however, other implementation options are possible. For example, the optical sensor can be used to obtain blood physiological information when it is installed on the wrist/upper limb, and the electrode can be used to obtain ECG signals when it is installed in front of the torso through the neck wear structure. In this case, the blood physiological information can be For continuous monitoring, for example, for continuous detection of heart rate, and then use the ECG signal for further confirmation, for example, when it is felt that there is a heart abnormality, for example, when there is a possible event of arrhythmia, the ECG signal is further recorded in real time The number, for example, is directly stored on the detection device, or is transmitted to an external device for storage, so as to confirm whether arrhythmia really occurs. Moreover, based on different implementation purposes, it can also be designed that the optical sensor only collects physiological signals when it is installed on the upper limbs, so as to save power consumption. Therefore, they are all feasible methods without limitation, and the key point is to provide users with convenient operation options.

In another embodiment, such a special electrode structure design is also suitable for two operation modes: wearing on the wrist to obtain ECG signals and hand-held operation to obtain ECG signals.

According to the special design of the shape, structure, and position of the housing and the electrodes, the first electrode and the second electrode are respectively distributed on the two ends of the housing, and the side surfaces of the two ends facing each other are as a whole. The setting range of the electrodes, in addition, the housing is designed to be elongated. Therefore, when the housing is not combined with any wearable structure, it is also suitable for handheld operation, as shown in Figure 5A, which can be held by one hand Hold one end of the shell and touch the electrode on the same side (any one of the five surfaces) at the same time, and then move the shell with the hand so that the electrode on the opposite side (any one of the five surfaces) touches other body parts, For example, the torso, the other hand, etc., to obtain ECG signals. In this case, whether it is the action of holding the hand or the action of the other end electrode touching other parts of the body, it provides a large-area and multi-directional contact. Choose, so that such an operation method will not be limited by the small size of the shell (for setting on the wrist), and the continuous arc surface design at the end provides operating comfort, plus no direction Sexual limitations (that is, either end can be used to be held by the hand or contact other parts of the body), therefore, is quite advantageous.

Among them, in particular, it can also be implemented as a way of holding both ends of the housing with both hands, as shown in Figure 5B, and such an operation mode further provides the heart projection formed by the two upper limbs without the need for a wrist-worn structure. It is also quite advantageous.

Therefore, it can be seen from the above that when it is implemented in a handheld form, especially in a single-handed form as shown in Figure 5A, preferably, electrodes are distributed on at least one of the two surfaces opposite to each other. , can make the contact between the electrode and the skin easier to achieve, and facilitate the operation.

Furthermore, if it is implemented as a situation where an optical sensor is also arranged on the lower surface of the housing, since the volume of the housing is small enough, the holding hand will naturally have at least one finger when holding it naturally and maintaining stability. Can be placed where the light sensor is placed, or, where the light sensor is placed on the upper surface, where the thumb would naturally rest, or where the light sensor is placed when held in the hand In this way, it is natural to obtain the blood physiological information while obtaining the ECG signal, and in addition to what the blood physiological information can provide, such as blood oxygen concentration, heart rate, etc. In addition to information, since such an action enables blood physiological information and ECG signals to be measured together naturally, the pulse transit time (Pulse Transit Time, PTT) can be further obtained through the correlation between the two physiological information , and knowing information such as blood vessel hardness/elasticity, can also be further estimated to obtain data related to blood pressure values, which has further advantages.

On the other hand, the special structural design described so far is also suitable for being shared by the two forms of neck wear and hand-held. In particular, through such a design, even if the neck-mounted structure is still installed in front of the trunk, it can be operated by hand without removing the neck-mounted structure. In addition, when the optical sensor is provided, The blood physiological information can be obtained from the chest and the holding hand respectively, and different operation options can be quickly provided.

Moreover, especially, based on the characteristic that the elongated housing is suitable for hand-held operation, a temperature sensing element 402 can also be provided at one end of the elongated housing, as shown in FIG. This end touches the skin to obtain body temperature, for example, forehead, armpit, etc., whether it is measured by itself or for others, as shown in Figure 5D, it is quite convenient; in addition, similarly, a light sensor 401 can also be set to Obtain blood physiological information, and also obtain blood physiological signals of oneself or others through such an operation method, for example, you can touch the fingers of your other hand, forehead, etc., or touch any position on other people's body that can obtain blood physiological information, Equally convenient.

On the other hand, the temperature sensing element and/or light sensor can also be arranged at the position that the holding hand will touch, so as to obtain body temperature and/or blood physiological information by touching the holding hand, and further without limitation , the temperature sensing element can be set at any position on the shell that will touch the skin when the shell is used to obtain body temperature information, for example, the shell may be placed under the armpit to obtain body temperature information, at this time, The position of the temperature sensing element can be placed at almost any position on the surface of the shell, and similarly, the optical sensor can also be set at any position on the shell, as long as the blood physiological information can be obtained, so it can be adjusted according to actual needs. And there are different needs, there is no limit.

Furthermore, in the second embodiment, according to the multiple physiological detection device of the present utility model, as shown in FIG. When worn on the front of the torso, it will be like wearing a pendant, which is quite burdenless, and the user only needs to press down the shell when necessary, so that the electrodes touch the skin of the torso, and then two electrodes can be obtained Simultaneously touch the heart projection formed by the chest.

Here, it should be noted that in addition to the cylindrical form, it can also be implemented as a long cylindrical form, for example, an elliptical cylindrical shape, or a cylindrical shape with a tangent plane, or a cylindrical shape with four flat surfaces, or a polygonal shape The columnar shape, etc., are not limited to the above-mentioned exemplified shapes in actual implementation, as long as the shell shape conforms to the principle of similar long cylinders, it all falls within the scope of this case.

As for the configuration of the electrodes, there are also a variety of options. One of the options is, as shown in FIG. 6A, two electrodes 110, 112 are respectively arranged at the two ends of the column body 160, and present a form that covers the two ends and extends to the column body; another option is that the first The electrodes are arranged on the column body, and the second electrode remains arranged on one end of the column body; another option is that both electrodes are arranged on the column body. Therefore, it can be changed according to actual usage requirements without limitation.

When the electrodes are configured as shown in Figure 6A, since both ends of the column body are surrounded by electrodes, no matter which direction the column body touches the torso, the contact between the two electrodes and the skin can be achieved, and the operation can be limited. is minimized, and such a configuration is especially suitable for implementation on non-directional cylindrical shells.

In addition, when a non-cylindrical shell is used to make the electrodes directional, similar to the previous description, the electrodes can also be naturally oriented to the torso through the design of the neck wear structure. For example, one of the options is to define the joint direction of the combination structure and the shell, so that the neck wear structure can be combined with the shell in a specific direction; another option is to implement the joint structure on the neck wear structure In order to accommodate the frame of the case, in this way, the direction of the case can also be easily restricted. In this case, it should be noted that after the case is placed in the frame, the electrodes must have exposed and accessible Parts of the torso, or, alternatively, in the case of a frame covering the electrodes, extending the electrodes on the housing to the outer surface of the frame for contact as previously described, are also feasible.

Here, it should be noted that the above-mentioned embodiments are only for example and not limiting, as long as the combination between the neck wearing structure and the shell can be achieved, and the contact between the electrodes on the shell and the torso can be effectively achieved , are optional.

Furthermore, the neck-wearing structure can be further implemented in a replaceable form. In addition to achieving the limit for the housing through the neck-wearing structure as described above, the material and size can also be replaced to suit different users. need.

On the other hand, it can also be combined with the wrist-worn structure 500, as shown in Fig. 6B. In this case, the two electrodes and the two upper limbs can be obtained by simply making contact with the other hand. Contact the resulting heart projection.

Furthermore, because it is implemented in a shape similar to a long cylinder, it is also suitable for implementation in a handheld form. As shown in Figure 6C, when the user holds one end of the cylinder with one hand, they can simultaneously touch the electrode at this end, and then move the cylinder through the holding hand to make other parts of the body of the other electrode, for example, the other upper limb, Trunk, etc., to obtain ECG at different projection angles. On the other hand, as shown in FIG. 6D , measurement can also be carried out by holding both ends of the elongated cylinder with two hands, which is also a very convenient and stable method. In this way, the heart projections of the upper limbs and the chest and the heart projections of the two upper limbs can be obtained respectively.

Here, it should be noted that although the electrode configuration shown in FIG. 6A is shown in FIGS. 6C-6D , other electrode configuration forms can also be implemented as a hand-held form, as long as the holding hand can touch one of the electrodes while holding it. , and the other electrode can touch other parts of the body when held by hand, there is no limit.

Moreover, especially, based on the characteristic that the long cylinder is suitable for hand-held operation, a temperature sensing element 402 can also be provided at one end of the long cylinder, as shown in FIG. It is quite convenient to obtain body temperature by touching the skin with the tip, for example, forehead, armpit, etc., whether it is measured by itself or for others, as shown in Figure 6F; in addition, similarly, a light sensor 401 can also be set to obtain Blood physiological information, and can also obtain blood physiological signals of oneself or others through such an operation method, for example, one can touch the fingers of the other hand, forehead, etc., and can also touch any position of other people's body that can obtain blood physiological information, the same Convenience. On the other hand, the temperature sensing element and/or the light sensor can also be arranged at a position where the holding hand will touch, so as to obtain body temperature and/or blood physiological information by touching the holding hand.

And further without limitation, the temperature sensing element may be placed at any position on the housing that will contact the skin when the housing is used to obtain body temperature information, for example, the housing may be placed under the armpit to To obtain body temperature information, at this time, the setting position of the temperature sensing element can be almost any position on the surface of the shell, and similarly, the optical sensor can also be set at any position on the shell, as long as the blood physiological information can be obtained. Yes, so it can be different according to actual needs, there is no limit.

Here, it should be noted that although Figures 6E-6F all depict the situation of setting the temperature sensing element and the light sensor at the same time, they are only used as examples, and only the temperature sensing element can be selected according to actual needs , light sensor only, or both at the same time, without limitation.

In addition, in yet another preferred embodiment, as shown in FIG. 6G , this type of long column is further implemented to be composed of a main body 182 and a housing 184, and through such a design, it will be possible to change electrodes and/or The possibility of the position and/or type of the sensing element, on the other hand, also provides a possibility of changing the structure of the neck wear. Wherein, the inside of the main body is used to accommodate the main circuit, and the electrical contact part (not shown) is exposed on the surface. On the other hand, the shell has a corresponding space for accommodating the main body, and has a corresponding The electrical contact part (not shown), so that the electrodes/sensing elements arranged on the surface of the housing can be electrically connected to the main circuit, so that the appearance of a long column can also be formed, and further, provide It is more advantageous to freely change the electrode/sensing element and the choice of neck wear structure.

On the premise that the above-mentioned various (as shown in Figures 1A, 3B, 4D, and 6A) can be respectively arranged on the front of the torso and the wrist, and can be implemented as a special shell structure in the form of one-handed or two-handed, further , this case also has special features in the implementation of the electrodes.

Since the electrodes of this case must be adapted to various forms of operation, each electrode will be distributed in more than one plane at both ends of the long axis of the elongated body, wherein, when the plane around the long axis is implemented as a single plane, for example, In the case of a cylinder, an ellipse, or a flat cuboid as shown in Figure 1A, since the shell only includes three planes, each electrode will be distributed on the end face at one end of the major axis and the surface surrounding the major axis. On the surface, when other shapes of shells are used, each electrode will be distributed on three surfaces, namely, the end surface at one end of the long axis and at least two surfaces connected to the end surface. And through such a special electrode distribution, even the same device can be adapted to a variety of different operating forms.

Furthermore, in addition to being distributed over multiple surfaces, it is important that the electrodes distributed over all surfaces are further implemented as a continuum, for example, a continuous electrode sheet covering multiple surfaces, or a single electrode with multiple accessible surfaces. Electrode blocks, wherein, when implemented as a continuous electrode sheet, the electrodes will be arranged on the surface of the casing, and when implemented as a single electrode block, the electrodes will be equal to replacing a part of the casing, that is, the electrodes The block will occupy a portion of the shell volume and be exposed and accessible. These two implementations have their respective advantages, and the choice can be made according to actual requirements without limitation.

Furthermore, since the above-mentioned various shell designs can be adapted to be arranged on the front of the torso and on the wrist, especially hope that it can be arranged on the wrist, it is natural to reduce the volume as much as possible, and in this case , when measuring with both hands, it may be difficult to hold, accordingly, it is optional to increase the volume by combining with other accessories to provide easier operation options.

For example, as shown in FIG. 7A and FIG. 7B , an additional gripping auxiliary structure 700 can be provided, and a gripping body can be formed by combining it with the housing, so that, through such a combination, in addition to The overall volume can be increased, and more importantly, the position of the electrodes can be changed accordingly, for example, to a position that is easier to access, or a position suitable for different operation behaviors, for example, Figure 7A shows two-handed holding Figure 7B shows the method of placing the holding body on a plane and then touching the electrodes with both hands. In addition, the holding body can also be implemented to be attached to the surface of a portable device, for example, the back of a mobile phone , At this time, the measurement can be carried out by holding both ends of the mobile phone with both hands and touching the electrodes at the same time, and the physiological signal changes during the measurement period can also be understood at the same time through the screen of the mobile phone. Therefore, there are various implementation possibilities without limitation.

Wherein, in order to change the position of the electrodes, one of the ways is that in the space for accommodating the housing in the gripping auxiliary structure, there will be electrode contact parts (not shown) corresponding to the positions of the two electrodes of the original housing. ), to extend the electrodes to the electrodes on the surface of the gripping auxiliary structure by means of electrical contact between the two; or, another embodiment is that when the two are combined, the electrodes on the original housing only include One is covered and extended, while the other electrode is exposed and not extended. Therefore, it can be changed according to different requirements during implementation without limitation.

In addition, when the housing combined with the holding aid structure has a light sensor, the holding aid structure can be further implemented to expose the light sensor for the user to obtain blood physiological information. In this case, if At the same time, by measuring the ECG signal, the pulse transit time (Pulse Transit Time, PTT) can be further obtained through the correlation between the two physiological information, and then information such as blood vessel hardness/elasticity can be obtained, which can also be further estimated. It is further advantageous to obtain data on the relevant blood pressure values. As for how the holding aid structure exposes the light sensor, there are different choices. For example, when implemented as the operation form shown in FIG. 7A, the holding aid structure may have an opening (not shown) on the lower surface, corresponding to to the position of the light sensor, so that the user can obtain blood physiological information by touching the light sensor located at the bottom of the device with any finger; It is directly exposed on the front side, so that the user only needs to use any finger to touch the light sensor on the housing while touching the electrodes on both sides, and can also obtain blood physiological information, so there is no limit.

Furthermore, in the fourth embodiment, the multiple physiological detection device according to the present case is mainly implemented as a hand-held operation, for example, it directly has a volume that is more suitable for hand-held operation, and then, through the interaction with the neck-worn structure The combined method enables the device to be placed in front of the torso and obtain ECG signals from the torso. Here, preferably, in order to comply with the two operation modes, the two electrodes can be arranged on the same surface of the casing, so that not only when the operation is performed in a hand-held manner, both hands can hold it naturally and To touch two electrodes, when it is set in front of the torso, it is only necessary to confirm that the surface with the two electrodes is facing the torso. Therefore, when the direction of contact with the trunk is confirmed, it is not easy to turn over and can be used naturally. Therefore, this is also a rather advantageous embodiment. Likewise, as mentioned above, the combination structure on the neck wear structure can be implemented as being directly combined with the shell, or can be implemented as a combination through an additional structure, such as a frame, without limitation.

Furthermore, in the fifth embodiment, this case proposes a multiple physiological detection device, which can also be respectively installed on the front of the torso and the wrist to measure the ECG signal, but has a simpler structural design. Please refer to FIGS. 8A-8B , wherein the housing is implemented as a flat body 800, and an electrode 810 and 812 are respectively arranged on two opposite surfaces at both ends of the shortest axis of the flat body, that is, the two electrodes are opposite to each other, so Firstly, when the neck-worn structure is used to set it in front of the torso, one hand can be used to press the electrode that is not in contact with the torso to achieve the setting of the cardiac projection where the two electrodes respectively contact the upper limbs and the torso. In addition, when the wrist-worn structure is used to set it on the When the wrist is used, the other hand can also press the electrode that is not in contact with the wrist to achieve the setting of heart projection where the two electrodes are respectively in contact with the two upper limbs.

Further, as shown in FIG. 8C, it can also be implemented that there are two electrodes 810a, 810b and a single electrode 812 on the two opposite planes respectively. In this way, when it is arranged in front of the torso through the neck wearing structure, a selection Two electrodes 810a and 810b contact the torso at the same time to obtain the heart projection of the torso; another option is to obtain the heart projection of the torso and upper limbs, at this time there are different operation options, one is to contact the torso with a single electrode 812 , and then by pressing at least one of the two electrodes 810a and 810b with one hand to obtain the heart projection of the trunk and upper limbs, the second is that the two electrodes 810a and 810b contact the trunk, and the electrode 812 contacts the pressing hand, that is, There is no restriction on the contact direction; another option is to obtain the heart projection of the torso and the heart projections of the torso and upper limbs at the same time. The electrodes 812 are contacted, so that two heart projections can be obtained simultaneously.

As for setting on the wrist, there is no direction restriction (not limited to that shown in Figure 8B), the wrist can be touched by the surface with two electrodes, or by the surface with a single electrode, and then the other hand can touch the uncontacted The electrodes on the wrist can all be taken from the heart projections of the two upper limbs.

On the other hand, it is also possible to achieve a measurement method in which two electrodes contact the torso at the same time through the design of the neck-wearing structure. As shown in FIG. A combined body is formed, and an electrode 814 is arranged on the combined structure, which is electrically connected to one of the electrodes 810 and 812 when the combined structure is combined with the flat body 800 (not limited to the one shown in the figure). Drawing), in this way, there can be two electrodes on the same surface of the combined body, and it can also be achieved that when worn on the front of the torso, two electrodes are in contact with the torso at the same time.

Such an electrode configuration method, in addition to providing another operation option, also makes the manufacturing easier, and can naturally reduce the manufacturing cost, which is indeed an advantageous implementation.

Furthermore, as mentioned above, an optical sensor can also be added to obtain blood physiological information, such as heart rate, blood oxygen concentration, and the like. Among them, preferably, the optical sensor is arranged on the surface facing the wrist, so that when worn on the wrist, the heart rate can be obtained continuously for long-term continuous detection, and , since it is originally equipped with ECG electrodes, if an abnormality is found during the continuous detection of heart rate, for example, a possible event of arrhythmia, the ECG signal detection can be performed immediately to confirm the accuracy of the event, and it can also be recorded in real time The following may be abnormal ECG signals, which is quite advantageous. In addition, the optical sensor can also be turned upwards, and the other hand can be touched to obtain blood physiological information, such as blood oxygen, heart rate, etc. At this time, if it is combined with simultaneous contact with the electrodes and obtained ECG signals, it can be further passed through two The Pulse Transit Time (PTT) can be obtained based on the interrelationship between these physiological information, and information such as blood vessel hardness/elasticity can be further estimated to obtain relevant blood pressure data, which also has advantages.

Here, it should be noted that the flat body can be in various shapes, for example, circular, oval, rectangular, polygonal, and irregular shapes, as long as it can conform to the front of the torso and the wrist, and Any shape that can achieve electrode contact is not limited.

In the sixth embodiment, this application further proposes a multiple physiological detection device and multiple physiological detection method, which can obtain ECG signals with different heart projection angles by changing the detection posture and changing the contact position. In this embodiment, the wrist-worn structure is adopted to carry the shell and is arranged on the user's wrist. At this time, just like all wrist-worn form detection devices described previously, there will be at least one electrode contact The skin of the wrist, and has at least one electrode exposed for touch, and in particular, in this case, this embodiment provides two contact location options, wherein the first contact location is, by another The upper limbs come to touch the contact position of the exposed electrode. At this time, what can be obtained is the projection angle of the two upper limbs. Furthermore, the second contact position is particularly shown in FIG. 9, which is the contact position where the exposed electrode contacts the trunk. For example, for the skin under the chest and abdomen, at this time, the projection angle between the upper limb and the chest can be obtained.

In general cognition, when the wrist-worn form is used, the acquisition of the ECG signal is to use another upper limb to contact the exposed electrode for measurement (as shown in Figure 4C). , it will adopt a handheld form (as shown in Figure 5A). Wearing it on the wrist can also obtain the heart projection of the upper limbs and torso, which is quite convenient. Wherein, it is preferable that, when it is implemented to touch the torso, the housing can be moved to the inner side of the wrist, so that the contact action is more smooth. In addition, although the drawing is shown as being worn on the left hand, the It is not limited, and it is also feasible to wear it on the right hand, as long as it conforms to the user's usage habits.

Such an operation method is especially suitable for the electrode configuration shown in Figure 8, that is, the two electrodes are located on opposite sides, and the user can easily achieve two-way contact. However, without limitation, as long as the device is worn On the wrist, having electrodes on the upward facing surface can perform such an operation, for example, one of the situations is, as shown in Figure 10A, when the case is placed on the wrist, other than touching In addition to the electrodes (not shown), the electrodes 901 for contacting the other upper limb and the torso are mainly distributed on the side surface connecting the upper surface and the lower surface, and there are electrodes extending from the side surface on the upper surface. , so that when contacting with the other hand, as shown in Figure 10B, the contact can be made by holding the side surface, and when contacting the torso, the contact can be achieved by the electrodes extending to the upper surface; or, another In the first case, as shown in FIG. 10C, the side surface and the upper surface respectively have electrodes 901a and 901b. For example, two electrodes can be implemented in parallel with each other (that is, using the same sampling circuit), or the two electrodes can be connected with each other. The electrodes on the lower surface form a sampling circuit, which also provides more convenient torso contact operation. In addition, it should be noted that, except that as shown in FIG. 10A , there are electrodes extending upward from the side surface on all sides of the upper surface, it can also be implemented in different situations, for example, extending upward from only one side (as shown in FIG. 10D ). shown), or only extending upwards on both sides, that is, as long as there are electrodes on the upper surface, there is no limitation.

Here, one of the preferred implementations is that the user wears the device on the wrist, and when necessary, first obtains the electrocardiographic projections of both hands by touching the exposed electrodes with the other hand. If it is found that the signal quality is poor or the signal strength is insufficient, for example, the measurement result can be obtained through an external device such as a mobile phone or the waveform can be obtained in real time, then the method of contacting the torso can be used instead to measure closer to the heart Obtaining a clearer and more stable ECG signal can be more helpful for interpretation and analysis. For example, a signal quality standard, such as S/N ratio, can be set as a standard for measuring whether further contact with the torso is required.

Another preferred embodiment is that during the measurement, the user is guided to operate through the user interface, for example, the display screen on an external device such as a mobile phone. For example, after the user starts the device, the user is first guided to perform The ECG signal acquisition of the two upper limbs, and then provide the measurement results to the user, and let the user choose whether to further capture the ECG signal of the torso, or directly guide the user to contact the torso ECG signal acquisition, that is, a single process includes the measurement of two contact positions. Therefore, all are feasible and there is no limit.

Or, when it is necessary to perform ECG signal detection, the user can also choose to directly measure the torso. For example, the user knows that the ECG signal of the two upper limbs of the user is relatively weak, or the user is taking the measurement in the removable clothes. occasions, etc., can be implemented according to the actual needs of users, and there is no limit.

Accordingly, when recording the ECG signal, it is preferable to accompany the contact position information, that is, the position information representing whether the electrode is in contact with the torso or the other hand. In this way, it will help more accurate and clearly analyzed and interpreted.

Furthermore, if the optical sensor is configured at the same time, as mentioned above, the optical sensor can be used to perform continuous detection on the wrist. When the obtained heart rate information is abnormal, for example, when a possible arrhythmia event occurs, a notification The user performs the detection of the ECG signal. At this time, the user can quickly and conveniently obtain the ECG signal of the two upper limbs by touching the exposed electrode with the other hand. If the quality of the obtained ECG signal is found to be poor, for example, it is not enough When analyzing, notify again to perform the ECG signal detection of the contact torso. Of course, alternatively, as mentioned above, the measurement of the two contact positions is also completed in the same process, or the user decides to contact for measurement position, there is no limit. In this way, it is equivalent to providing a more convenient but foolproof execution process for users, which is quite advantageous.

As far as ECG signal detection is concerned, the wrist-worn form is generally considered to be the most convenient and most accepted by the public. As for the measurement method of touching the torso, the strongest ECG signal can be obtained. As far as the detection field is concerned, it is indeed a brand-new concept different from the past, and it has considerable advantages.

In addition, in all the above-mentioned various embodiments, a motion sensing element can be further added to the device, for example, an accelerometer (Accelerometer), a gravity sensor (G sensor), a gyroscope (gyroscope), a magnetic sensor (Magnetic sensor) sensor), etc., 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. And, further, since it is implemented as a wearable form, when a motion sensing element is provided, the physiological detection device according to the present utility model can also be further used as a so-called activity recorder (actigraph) to provide information such as walking Various information such as steps, moving distance, calorie consumption, fall detection, sleep physical activity, daily activity, 24-hour activity distribution, etc., which also help users better understand their own physiological state information, which is also quite useful Advantage.

In addition, a temperature sensing element can also be added, which is arranged at a position in contact with the skin surface to obtain information related to body temperature, which can help to further understand the actual physiological conditions.

Furthermore, the device according to the present invention preferably also includes a wireless transmission module, such as a Bluetooth module, to wirelessly transmit the obtained physiological information to external devices, such as smart phones, smart watches, tablets, Computers and other devices that have wireless transmission functions and can execute corresponding application programs, and this transmission can be implemented as real-time wireless transmission, or after the physiological monitoring is completed, and therefore, the housing can also be set The internal memory is used to store the obtained physiological signals and download them to an external device after the monitoring is completed.
