Detailed ways

The structural principle and working principle of the present invention will be specifically described below with reference to the accompanying drawings:

1A and 1B, FIG. 1A is a top view of a wearable device 100 for detecting an electrical signal on a surface of a human body, and FIG. 1B is a cross-sectional view of the wearable device 100 of FIG. 1A along a direction 1B-1B'. .

The wearable device 100 includes a wearable carrier 110, at least one detecting unit, a first wire 130, a processor 140, and a wireless communication unit (not shown). The detection unit is for example the first contact 120. In the present embodiment, the wearable carrier 110 is, for example, one or any combination of pants, clothes, belts, buttons.

The first contact 120 is disposed on the wearable carrier 110 for measuring or receiving the detection electrical signal of the selected surface of the skin surface of the human body P and the detection position signal corresponding to the detection electrical signal. The processor 140 can be configured on the wearable carrier 110 and electrically connected to the first contact 120. The processor 140 is configured to process the detection electrical signal S1 and the detection position signal, and determine the target electrical signal and the target position signal from the selected area, wherein the electrical signal and the detected position signal are, for example, the meridian or the acupuncture point P1 or the surrounding area. Signals (such as resistors or capacitors or electromagnetics) and position signals.

The meridian here refers to the twelve meridians existing in the human body P, or other known or unknown meridians. In terms of twelve meridians, it includes the hand Taiyin lung meridian, the hand Yangming large intestine, the foot Yangming stomach, the foot Taiyin spleen, the hand Shaoyin heart, the hand sun small intestine, the foot yin and liver, the foot less Yangdanjing, hand Shaoyang Sanjiaojing, hand sputum Yinxinbaojing, foot Shaoyin kidney meridian and foot sun bladder.

In addition, the outer diameter of the first contact 120 may match the outer diameter of the acupuncture point P1. For example, the outer diameter of the acupuncture point P1 is between 3 cm and 5 cm, so the outer diameter of the first contact 120 of the embodiment may be between 3 mm and 5 mm, depending on the demand, or 3 mm. Below or 5 mm or more.

The first wire 130 can be disposed on the wearable carrier 110 and connected to the first contact 120 to transmit the detection electrical signal S1 of the human body meridian or the acupuncture point P1 to the processor 140.

In another embodiment, the processor 140 can be configured in an external smart device, such as a cell phone or a computer. In this design, the wireless communication unit (not shown) of the wearable device 100 is disposed on the wearable carrier 110. The processor 140 is separately designed from the wearable carrier 110 and electrically connected to the first contact 120 through the wireless communication unit. connection. The wireless communication unit can transmit the detected electrical signal S1 to the processor 140 disposed on the external device for the processor 140 to process and/or analyze the detected electrical signal S1. As a result, the design complexity and/or workload of the wearable device 100 can be alleviated.

Modern medicine has found that the human body has many "good guides" formed by lower electrical signal values (such as resistance, but not limited to this) compared with normal skin, which verifies the existence of meridians and acupuncture points. Under different pathological or physiological conditions, the electrical signals of the corresponding acupoints fluctuate. The wearable device 100 of the embodiment of the present invention can obtain the detection electrical signal S1 of the acupuncture point and the detection position signal, and the processor 140 can analyze the detection electrical signal S1 and the detection position signal to obtain the physiological state of the human body P. In addition, the detection electrical signal S1 can be compared with a reference reference signal, and the physiological state of the human body P can also be known by analyzing the electrical signal difference between the electrical signal S1 and the reference reference signal. The reference signal can be obtained by contacting a contact (not shown) of the processor 140 with a non-acupoint or non-meridal point of the human body P; alternatively, the reference reference signal can also be a ground signal. In addition, the contact point of the contact point and the reference reference signal are in a loop to detect the signal of the acupuncture point. In one embodiment, the reference reference signal is a ground signal, wherein one first contact 120 contacts the acupuncture point P1 and the other first contact 120 contacts the non-acupoint, and then the signal of the first contact 120 and the other first contact 120 The difference in signal can be used as the electrical signal difference of this paper.

In order to detect the electrical signal as a resistance, since the acupoint is in a state of lower resistance (compared to a non-acupoint), the resistance of the meridian or acupoint P1 may react or fluctuate as long as the physiological state of the human body changes. Therefore, the wearing device 100 of the embodiment of the present invention can accurately detect the physiological state of the human body P.

As shown in FIG. 1B , the first contact 120 and the first wire 130 are respectively disposed on opposite sides of the wearable carrier 110 , and the conductive portion 125 connects the first wire 130 and the first contact 120 to electrically connect the two. The conductive portion 125 is buried in the wearable carrier 110. The conductive portion 125 is, for example, a conductive hole, a conductive line, a conductive block or other element or material that electrically connects the first contact 120 and the first conductive line 130. In another embodiment, the wearable device 100 can further include a covering layer (not shown) that can cover the first joint 120 and/or the first wire 130 to prevent exposure to the environment.

As shown in FIG. 1B, the position of the first contact 120 is located at a point on the skin corresponding to the meridian, such as the acupuncture point P1, so that the detection electrical signal S1 of the acupuncture point P1 or the meridian can be transmitted through the first contact 120, the conductive portion 125 and the first wire 130. To the processor 140.

In addition, in order to position the acupuncture point P1, a conductive sheet 11 may be preliminarily attached to the acupuncture point P1 of the human body P to display the position of the acupuncture point P1. Both sides of the conductive sheet 11 are viscous, so that the first contact 120 and the human body P can be adhered to prevent the first contact 120 from easily escaping or shifting the body meridian.

In another embodiment, the wearable device 100 further includes a conductive sheet 11 that can be pre-adhered to the first contact 120. When the wearing device 100 is to be used, the conductive sheet 11 is further removed from the first contact 120 and then adhered to the skin to display the position of the acupuncture point P1; or, the wearing device 100 is directly removed without tearing off the conductive sheet 11. The upper conductive sheet 11 is adhered to the human body P.

In other embodiments, the wearable carrier 110 may have elasticity that can be closely attached to the human body P; in this design, even if the conductive sheet 11 is omitted or the first contact 120 is not viscous, the wearable carrier The tightness effect provided by the 110 allows the first contact 120 to still be in close contact with the human body P, thus reducing the relative motion between the first contact 120 and the human body P.

2 is a top plan view of a wearable device 100 in accordance with another embodiment of the present invention. In this embodiment, the first contact 120 itself may have a viscosity. Under this design, the conductive sheet 11 can be omitted, so that the first contact 120 directly contacts the human body P.

3A and 3B, FIG. 3A is a schematic diagram of a wearable device 200 according to another embodiment of the present invention, and FIG. 3B is a schematic view of the wearable device 200 of FIG. 3A being worn on a human body P.

The wearable carrier 210 of the present embodiment is an example of a sleeve that can be placed over the arm. In another embodiment, the wearable carrier 210 can be a pants, a garment, a belt, a button, or the like.

In this embodiment, the plurality of first contacts 120 are disposed on the wearable carrier 110 for electrically connecting at least one point on the same meridian of the human body P or multiple points on different meridians, and receiving the measurement points. The electrical signal S1 is individually detected, such as a resistor, capacitor or other type of signal.

As shown in FIG. 3B, the number of the first contacts 120 in this embodiment is exemplified by four, wherein the first contact 120' is electrically connected to the ruler hole, and the first contact 120" is electrically connected to the Quze point. The first contact 120"' is electrically connected to the Shaohai hole, and the first contact 120"" is electrically connected to the most hole of the hole. In another embodiment, the number of first contacts 120 may be less than or more than four, which may be electrically connected to any of a plurality of acupuncture points P1 of the human body P. The ruler hole belongs to the hand Taiyin lung meridian, and the Shaohai point belongs to the hand Shaoyin heart. It can be seen that the wearable product 100 of the embodiment of the invention can be used for a plurality of different meridians.

The plurality of first wires 130 are disposed on the wearable carrier 210, and each of the first wires 130 is connected to the corresponding first contact 120 to transmit the detection electrical signal S1 of the human body meridian to the processor 140.

The processor 140 can be configured on the wearable carrier 210 for analyzing the detected electrical signal S1 from the human body meridian.

In an analysis method, one of the plurality of first contacts 120 may measure the non-meridian (or non-acupoint P1) detection electrical signal S1 and serve as a reference reference signal, while the other first contacts 120 may measure The electrical signal S1 is detected at any point on the meridian. A loop can be formed between the contact of the measurement and detection electrical signal S1 and the contact of the detection electrical signal S1 of the non-meridian (or non-acupoint P1). The processor 140 can calculate the detected electrical signal difference between the detected electrical signal S1 on the meridian and the non-acupoint. The processor 140 analyzes the physiological state of the human body P based on the detected electrical signal difference. Similarly, the processor 140 of the wearable device 100 of FIG. 1A can provide a reference reference signal, and the processor 140 can calculate the difference between the detected electrical signal S1 of the first contact 120 and the reference reference signal as an electrical signal difference. The processor 140 analyzes the physiological state of the human body P based on the electrical signal difference.

Each of the second contacts 450 is connected to the corresponding first contact 120 through the corresponding first wire 130, so that the detected electrical signal S1 of the meridian or the acupoint P1 is transmitted to the second contact 450 through the first contact 120 and the first wire 130. In this embodiment, the plurality of second contacts 450 can be concentrated in a small area; thus, in one connection operation, the analyzer 460 can interface with all of the first contacts 120.

As shown in FIG. 4C, the corresponding third contact 461 and second contact 450 may be a conductive buckle set. For example, the third contact 461 is, for example, a male end, and the second contact 450 is, for example, a female end having a recess 450r to receive the third contact 461. When the third contact 461 of the analyzer 460 is in contact with the second contact 450, each of the third contacts 461 can be fastened into the recess 450r of the corresponding second contact 450 to be electrically connected to each other.

Next, a method of detecting an electrical signal according to an embodiment of the present invention will be described.

FIG. 7A is a flow chart showing the process of detecting electrical signals of acupuncture points according to an embodiment of the invention. In step S11, a plurality of detecting units, such as the first contact 120, are provided to detect a detected electrical signal S1 in the selected area of the human skin surface and a detected position signal corresponding to the detected electrical signal S1. In step S12, the processor 140 processes the detected electrical signal S1 and the detected position signal to determine a target electrical signal and a target position signal from the selected region.

FIG. 7B is a flow chart showing the process of detecting electrical signals of acupuncture points according to another embodiment of the present invention. In step S21, at the first time point, the first detection electric signal and the first detection position signal of each detection unit are detected and acquired. In step S22, the relative magnitudes of the first detected electrical signals are compared, and the first detected electrical signal is determined to be the target electrical signal or a non-target electrical signal based on the relative magnitudes of the first detected electrical signals. In step S23, the target electrical signal and the target position signal corresponding to the target electrical signal are analyzed to determine a reading of the target position signal, and a target electrical signal reading representative of the target position signal is obtained.

In another embodiment, the aforementioned point in time may include more points of detection. For example, at the first to Nth time points, N is an integer greater than 1, and the first to Nth detection electrical signals and the first to Nth detection position signals of the respective detection units are detected. The operation mode at each time point is similar or the same as the step of FIG. 7B, and details are not described herein again. In addition, the time interval of the second time point of this embodiment is less than a value between 0.01 seconds and 2 seconds.

The aforementioned numerical analysis may include a variance operation or a regression operation, and the read value is obtained using an average, regression or minimum variance operation.

The signal processing method using matrix operation according to another embodiment of the present invention is exemplified below.

FIG. 8 is a flow chart showing the process of detecting an electrical signal of acupuncture points according to another embodiment of the present invention.

In step S102, as shown in FIG. 9, the plurality of first contacts 120 of the wearable device detect the detected electrical signals in the selected area of the human skin surface and the detected position signals corresponding to the detected electrical signals. These first contacts 120 may be arranged in a matrix shape, such as a matrix shape arranged in m×n, where m and n are positive integers equal to or greater than 1, and m and n may be equal or different. In another embodiment, each of the first contacts 120 may be annular, and the plurality of first contacts 120 may be arranged in a concentric ring shape as shown in FIG.

The area of the acupuncture point P1 may overlap with the area of the plurality of first contacts 120 at the same time, and the area of the plurality of first contacts 120 is larger than the area of the acupuncture point P1, so that when the wearable carrier 110 and the acupuncture point P are offset, the acupuncture point P The signal can still be detected by at least one first contact 120.

In step S104, at the first time point, the first detected electrical signal of each of the first contacts 120 is obtained. As shown in the matrix M1, these first detected electrical signals are listed as the first row (j = 1) of the matrix M1, such as a _i,1 .

In step S106, at the second time point, the second detected electrical signal of each of the first contacts 120 is obtained. In the matrix M1 as shown above, these second detected electrical signals are listed as the second row (j=2) of the matrix M1, such as a _i,2 . With this principle, at the jth time point, the detected electrical signals of the respective first contacts 120 are obtained and arranged in the jth row of the matrix M1.

In more detail _, the column (i) of the elements a _i,j of the matrix M 1 represents one of the first contacts 120, and the row (j) represents the first contact 120 of the first contact 120 at the jth (or jth) Detection signal at a time point). For example, a _2,3 represents the signal detected by the second first contact 120 in the third signal detection. In addition, the detection of j times (j is greater than or equal to 2) can be completed in a time interval, such as in one second, so that the signal processing of the embodiment of the present invention can achieve the technical effect of quickly and instantaneously reading the value of the acupoint signal. Depending on the amount of misalignment between the wearable carrier 110 and the acupuncture point P1, each of the first contacts 120 may change at each detection signal.

In step S108, the relative sizes of the first detected electrical signals are compared. For example, compare the numerical magnitudes of all elements of the first row (j=1) in matrix M1.

In step S110, the first detected electrical signals are distinguished as acupoint signals or non-acupoint signals according to the relative sizes of the first detected electrical signals. For example, the signals of the elements a _2,1 , a _3,1 and a _6,1 are lower in value than the surrounding elements, so they are judged to be acupoint signals from the acupuncture point P1, and other higher detected electrical signal values. The signal of the element is determined to be a non-acupoint signal.

Steps S108 and S110 can be performed by analysis of variance, regression analysis or other suitable methods.

In step S112, the acupressure signals of the first detected electrical signals are processed to obtain a reading representative of the acupuncture points P1. For example, the average values of the elements a _2,1 , a _3,1 and a _6,1 can be expressed as the reading of the acupuncture point P1 at the first time point. However, the reading of the acupoint P1 at the first time point can also be obtained in other ways.

In step S114, the relative sizes of the second detected electrical signals are compared. For example, compare the numerical values of all the elements in the second row (j=2) in the matrix M1.

In step S116, the first or second detected electrical signals are distinguished as acupoint signals or non-acupoint signals according to the relative sizes of the second detected electrical signals and the first detected electrical signals. For example, the values of the signals of the elements a ₅ , ₂ , a ₆ , ₂ , a ₈ , ₂ , and a _{9, 2} are lower than those of the peripheral elements, and thus are judged to be acupuncture signals from the acupuncture point P1 (target electrical signals) ), other signals of elements that detect higher electrical signal values are determined to be non-acupoint signals.

In step S118, the acupoint signals of the second detected electrical signals are processed to obtain a reading representative of the acupuncture points P1. For example, the elements a ₅ , ₂ , a _{6 × 2} , a ₈ , ₂ and a _{9, 2 may} be averaged, and this average value is expressed as the reading of the acupuncture point P1 at the second time point. However, the reading of the acupuncture point P1 at the second time point can also be obtained in other ways.

The analysis of the elements of the other rows (j) of the matrix M1 is similar to the elemental analysis of the first row and the second row, and will not be described again.

After comparing the signal detection of two or more times (different j-th row), it can be found that even if a misalignment occurs between the wearable carrier 110 and the acupuncture point P1, the signal of the acupuncture point P1 can be detected by at least one first contact 120. By comparing the changes in the acupoint signals of the rows (j), the degree of deviation between the acupuncture points P1 and the wearable device can be known.

In another embodiment, the region of the plurality of first contacts 120 of FIG. 9 can include two acupuncture points P1. In this case, if the signals of the elements a _2,1 , a _3,1 and a _6,1 are judged as acupoint signals from the acupuncture point P1, the elements a _2,1 and a _3,1 represent one of the acupuncture points P1. Signal, while a _6,1 represents the signal of another acupoint P1. That is to say, through the signal analysis of the matrix M1, the detected electrical signals of the plurality of acupuncture points P1 can be obtained. As for how to determine which acupoint signal of those elements of the same row belongs to which acupoint P1 can be done by ANOVA or other suitable methods.

Moreover, the signal processing described above can be performed by the processor 140.

FIG. 11 is a flow chart showing the process of detecting an electrical signal of acupuncture points according to another embodiment of the present invention.

In step S202, at the first time point t1, the first detected electrical signal of each of the first contacts 120 is obtained. The matrix M2, t1 at the first time point t1 as shown below. As shown by the matrix M2, the relative positions of the elements a _{i, j} correspond to the relative positions of the first contacts 120 in FIG. For example, the plurality of first contacts 120 of FIG. 9 are arranged in a 3×3 matrix, and the matrix M2 is also a 3×3 matrix. The signal of the element a _i,j represents the signal detected by the first contact 120 at the i, jth position at time t.

In step S204, the numerical values of all the elements in the matrix M2, t1 at the first time point t1 are compared.

In step S206, the first detected electrical signals are distinguished as acupoint signals or non-acupoint signals according to the relative magnitudes of the first detected electrical signals, wherein the values of the acupoint signals are relatively smaller than the values of the non-acupoint signals. For example, the signals of the elements a _1,1 and a _1,2 are lower in value than the surrounding elements, so they are judged to be acupoint signals from the acupuncture point P1, while the signals of other elements that detect the electrical signal value are It is judged to be a non-acupoint signal.

Step S206 can be performed by analysis of variance or other suitable method.

In step S208, the acupressure signals of the first detected electrical signals are processed to obtain a reading representative of the acupuncture points P1. For example, the average values of the elements a _1,1 and a _1,2 can be expressed as the reading of the acupuncture point P1 at the first time point t1. However, the reading of the acupuncture point P1 at the first time point t1 can also be obtained in other ways.

The signal processing at the second time point t2 (steps S210 to S216) is similar to steps S202 to S208, and will not be described again. The signal processing at other time points is similar to steps S202 to S208, and details are not described herein again.

After comparing the matrix M2 at two time points t or a plurality of time points t, it can be found that even if a misalignment occurs between the wearable carrier 110 and the acupuncture point P1, the signal of the acupuncture point P1 can be detected by at least one first contact 120. By comparing the changes in the acupoint signals of the plurality of matrices M2, the degree of misalignment between the acupuncture points P1 and the wearable device can be known.

Although the above embodiment is described by taking an acupuncture point P1 at each time point as an example. In another embodiment, more than two acupuncture points P1 can be detected at each time point. Moreover, the signal processing described above can be performed by the processor 140. For example, as shown in FIG. 12, a functional block diagram of a processor 140 in accordance with an embodiment of the present invention is shown. The processor 140 includes a signal acquisition unit 141, an electrical signal processing unit 142, and a position signal processing unit 143.

The signal acquisition unit 141 is electrically connected to the detection units, and acquires the detection electrical signal S1 of the detection unit and the detection position signal corresponding to the detection electrical signal S1. The electrical signal processing unit 142 performs an analysis process of detecting the electrical signal S1 to determine a reading value of the target electrical signal. The position signal processing unit 143 performs analysis processing of the detected position signal to determine the reading value of the target position signal.

The invention may, of course, be embodied in a variety of other embodiments without departing from the spirit and scope of the invention. Changes and modifications are intended to be included within the scope of the appended claims.
