Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but not to limit the present invention.

Here, it should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only the structures and/or processing steps closely related to the solution according to the present invention are shown in the drawings, and the related structures and/or processing steps are omitted. Other details not relevant to the invention.

It should be emphasized that the term "comprising/comprising" when used herein refers to the presence of a feature, element, step or component, but does not exclude the presence or addition of one or more other features, elements, steps or components.

Here, it should also be noted that, if there is no special description, the term "connection" herein may not only refer to direct connection, but also to indicate indirect connection with intermediates.

It should be noted in advance that the "proximal phalanx" in this application refers to the phalanx close to one end of the palm, and the "distal phalanx" refers to the phalanx away from the end of the palm. The "subject" is a user who wears the multi-physiological indicator collection device described in this application to detect and collect physiological characteristic data.

In the process of detecting physiological index data in vitro, there are significant differences in the detected values obtained in different parts of the human body due to differences in the structure and function of different parts of the human body. Therefore, in order to obtain more accurate physiological index data, it is necessary to perform detection at a position where the physiological index data is more sensitive to changes. For example, galvanic data is the electrical resistance or conductance data of the skin, which varies with the function of the skin's sweat glands, and can be used to reflect changes in the subject's mood. Increased perspiration leads to increased electrical conductivity. However, there are significant differences in the secretion of sweat glands in different parts of the human body, resulting in inconsistent representation levels of the electrical skin data collected from different parts. For example, under the same situation, the electrical skin electrical change level of the wrist is significantly lower than that of the palm, and the electrical skin electrical change of the palm is significantly lower than that of the fingertips. .

In the prior art, special medical equipment generally detects physiological index data through multiple fingers, which is cumbersome to wear and complicated to detect. Wearable intelligent detection equipment generally detects the wrist or earlobe, and the detection is still not sensitive enough.

The sensor 1045 is used to receive the beam reflected by the infrared light emitter 1043 and the red light emitter 1044 through the skin to detect the heart rate and blood oxygen saturation; The location of the electrical collection electrodes 1042 corresponds to the distal phalanx of the finger.

The data acquisition module 201 is disposed inside the main casing 101 and is used to collect data information generated by the first galvanic acquisition electrode 1041 , the second galvanic acquisition electrode 1042 , the photoelectric sensor 1045 and the dermal temperature sensor 1046 .

In this embodiment, the present invention is based on single-finger detection, the main casing 101 may be a rectangular structure, and the side for arranging the sensor is the detection end surface. Since the human body's fingers are cylindrical, in order to fit the shape of the finger and facilitate wearing, and to enable the sensor disposed on the detection end face to fit the finger for detection, a groove 102 is provided on the detection end face of the main casing 101 to make wearing more stable. The grooves 102 can be set to have the same width, and can also be set to be wider near the proximal phalanx and narrower near the distal phalanx according to the shape of the fingers.

During the wearing process, the subject places the finger in the groove 102, wraps the strap 1011 around the finger, and connects the buckle 1013 through the buttonhole 1012 on the strap 1011 to achieve fixing. In other embodiments, the fixing member may also adopt a splint member, and the splint member is connected to the main housing 101 through a spring for clamping the subject's finger.

The sensor assembly 104 is used to collect various physiological index data, and may include various sensors, wherein the first galvanodermal collecting electrode 1041 and the second galvanic skin collecting electrode 1042 are used for collecting galvanic skin data. By detecting the magnitude of the current between the first electrical skin collecting electrode 1041 and the second electrical skin collecting electrode 1042, the electrical skin data information is obtained by processing, so as to reflect the emotional change of the subject. Since the present application performs detection based on a single finger, in order to make the galvanic data accurately reflect emotional changes, it is required that the two electrodes cannot be too close or too far away, resulting in the inability to detect the variation of galvanic data. In this embodiment, the position of the first galvanodermal collection electrode 1041 is set to correspond to the proximal phalanx of the finger, and the position of the second galvanodermal collection electrode 1042 is set to correspond to the distal phalanx of the finger, which can effectively ensure the accurate detection of galvanic data. out. The external light emitter, red light emitter 1044 and photoelectric sensor 1045 detect heart rate by photoplethysmography, by shining light into the skin and measuring light scattering due to blood flow, when the hemodynamics changes, such as When the pulse rate (heart rate) or blood volume (cardiac output) changes, the light entering the body will be scattered predictably, and the heart rate data can be obtained from the change of the scattered light. In the same way, since the blood vessel distribution of the finger is denser than other parts of the human body, the data obtained by using the finger as the detection point is more accurate.

After the filtering is completed, enter the The processor module 202 performs data processing, converts the analog data signal into a digital signal, and then sends the electrical skin data signal through the wireless transmission module 203; after the photoelectric sensor 1045 that collects pulse PPG and blood oxygen SPO2 collects the light signal, the The first signal amplification circuit 301 amplifies the analog signal.

The skin temperature sensor 1046 collects the skin temperature, and the temperature collection uses the method of thermal conduction to measure the skin temperature. The skin temperature is introduced into the temperature probe, and the skin temperature sensor 1046 will output an analog signal.

The present application optimizes the measurement location and circuit of the skin electricity. The traditional electrodermal measurement is to collect data through the fingertips of any two fingers. Due to the long distance between the two fingers, the device is inconvenient to wear. In this application, two electrodes are collected on one finger, and the measurement is performed through the proximal phalanx and distal phalanx of the finger. Compared with the traditional electrodermal measurement method, the measurement method is more convenient, and the test effect is similar to that of the finger. Traditional galvanic measurements showed the same trend. When people suffer from emotional fluctuations, the most obvious part is the fingertips. The main feature is sweating. Due to the discharge of sweat, the skin resistance will decrease, which will lead to an increase in the skin electrical level. Since the sweat-sensitive parts of people are on the fingertips, and the proximal phalanx is not easy to sweat, the amplitude of the measured galvanic skin response value is low. In this application, the signal amplifier is increased by 10 times to track the skin The change of the electrical reaction makes the reaction trend more obvious.

Further, the present invention also detects whether the finger is online. When the subject performs the detection, the present invention will detect whether the finger is online, that is, whether it is effectively worn. It can perform 3-dimensional detection, electrical skin detection, pulse detection and skin temperature detection. Assume that the detection value of skin electricity is E1; the detection value of pulse is P1; the detection value of skin temperature is T1; start the test, if the detection value of skin electricity is E1=0, it means that the finger is not placed well, and the measurement of other indicators stops, prompting Put the finger in place; if the detected value of the pulse is P1>200 or P1<40, it means that the finger is not in place, and the measurement of other indicators stops, indicating that the finger is in place; if the detection value of skin temperature T1<30, it means that the finger is not in place, The measurement of other indicators stops, and prompts to place the finger; if the detected finger is not placed for more than 1 minute, the system sleeps.

To sum up, the multi-physiological index collection device, based on a single finger for detection, is convenient to wear and carry. By detecting a single finger, in particular, the positions of the first and second galvanodermal acquisition electrodes correspond to the proximal control bone and the distal phalanx of a single finger, respectively, so that the collected physiological index data can be obtained. Higher precision and better characterization. At the same time, by adding a signal amplifying circuit in the circuit structure, the detected physiological index data signal is made clearer.
