Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The practice of exercise or heat and depression often involves a large amount of perspiration, which can lead to an imbalance of electrolytes in the human body, and can cause a series of health problems if body fluids and necessary electrolytes are not replenished in time. However, at present, no wearable device is available for detecting the electrolyte content in the body of the user at any time, and the health condition of the user cannot be monitored in time.
Because the sweat secreted on the surface of the human body can fully reflect the electrolyte loss condition of the human body, if the sweat on the surface of the skin of the user can be obtained and analyzed, the electrolyte content in the body of the user can be known, and the body health of the user can be monitored in time. Based on this, this application has proposed a wearing equipment, and this wearing equipment both includes the wearing equipment body, also includes sensing component. The back of the wearable device body is provided with at least one opening, part or all of the at least one opening is provided with a capillary tube, the capillary tube is tightly attached to the inner wall of the opening, and the capillary tube is used for extracting liquid to be detected on the surface of the skin of a user; the sensing assembly comprises a sensing element, and the sensing element is arranged in the capillary; the sensing assembly is used for determining the electrolyte content in the body of the user according to the liquid to be detected extracted through the capillary tube.
Fig. 1 is a schematic structural diagram of a wearable device provided in the present application, where the wearable device includes a wearable device body and a sensing assembly (not shown in fig. 1). For example, the wearable device may be a smart band.
As shown in fig. 1, the back of the wearing device body is provided with at least one opening 11, a capillary tube 12 is arranged in each opening of the at least one opening, the capillary tube 12 is tightly attached to the inner wall of the opening, when the wearing device is worn by a user, the opening 11 and the opening of the capillary tube 12 inside the opening can be tightly attached to the skin of the user, and the capillary tube 12 is used for extracting a liquid to be detected on the skin surface of the user, for example, extracting sweat exuded from the skin surface of the user.
When wearing equipment is intelligent bracelet, for reducing process flow, reduce the wearing equipment structural design degree of difficulty, promote the pleasing to the eye degree of its outward appearance, this at least one trompil can reuse the peripheral space of the charging electrode at the back of wearing equipment body, sets up the capillary in the peripheral space of at least one charging electrode at the back of wearing equipment body promptly.
For the accuracy of guaranteeing to detect, simultaneously in order to reduce the influence of capillary to other functions and the performance of wearing equipment, also can set up special trompil at the back of wearing equipment body, set up the capillary in special trompil.
The liquid to be detected can be sweat, because the open pore 11 is tightly attached to the skin of the user, when sweat seeps out from the skin at the attached part, the sweat enters the capillary 12 in the open pore and ascends along the inner wall of the capillary 12, so that the capillary 12 can play a role in guiding flow, and the flow track of the sweat can be limited. The height of the liquid to be detected in the capillary 12 can be determined according to equation (1):
wherein h represents the height of the liquid to be detected in the capillary, ρ represents the density of the liquid to be detected, r represents the radius of the capillary, θ represents the intersection angle of the liquid level of the liquid to be detected and the pipe wall, σ represents the tension of the liquid surface and is related to the type of the liquid, and g represents the gravity acceleration. Therefore, the rising height of the liquid to be detected in the capillary and the radius of the capillary are in inverse proportion, in order to improve the detection sensitivity, the capillary can be arranged to be thin, for example, the diameter of the capillary can be 0.1mm, in this case, even if only a small amount of sweat on the surface of the skin seeps out, enough sweat can be collected in the capillary, and then the electrolyte content in the body of the user can be determined through the collected sweat. In order to improve the stability of the capillary, the inner diameter of the opening and the outer diameter of the capillary should be close to each other as much as possible, so that the capillary is tightly attached to the inner wall of the opening, the capillary is placed to incline, and the accuracy of a detection result is affected.
The sensing assembly is used for determining the electrolyte content in the body of the user according to the liquid to be detected extracted by the capillary tube. The sensing assembly includes a sensing element disposed within the capillary tube. The sensing assembly is used for determining the electrolyte content in the body of the user according to the liquid to be detected extracted by the capillary tube. The essence of the method is that the liquid to be detected seeping from the skin surface of the user is sampled, and then the electrolyte content in the user is determined by analyzing the sample.
To improve the accuracy of the detection, sweat on the surface of the user's skin may be extracted through a plurality of capillaries. Because the capillary sets up in the trompil, therefore correspondingly, can set up a plurality of trompils, a plurality of trompils can set up the different positions at the wearing equipment body back for obtain the liquid of waiting to detect in the different positions on user's skin surface. For example, the number of openings may be two.
Optionally, the sensing assembly further comprises a detection module.
The sensing element of the sensing assembly is used for measuring the voltage of the liquid to be detected at different positions.
The detection module is used for determining the electrolyte content in the user body according to the voltages of the liquid to be detected at different positions.
The electrolyte content in the liquid to be detected has certain influence on the conductivity of the liquid, namely the resistance value of the liquid to be detected. Specifically, the higher the electrolyte content is, the smaller the resistance value of the liquid to be detected is; the lower the electrolyte content, the greater the resistance of the liquid to be tested. When the liquid to be detected in the capillary is electrified, the resistance value is reflected on the voltage, and the voltages of different positions of the liquid to be detected are different due to the change of the concentration of the electrolyte in the liquid to be detected. For example, the concentration of sodium chloride in sweat varies, and the sweat has a different conductivity. The larger the content of sodium chloride is, the stronger the conductivity of sweat is, and the smaller the resistance value is; the smaller the sodium chloride content, the poorer the conductivity of the sweat and the larger the resistance. When the sweat in the capillary is electrified, the voltage of the sweat at any position in the capillary is different due to the change of the electrolyte content in the sweat.
Specifically, the detection module is used for determining the difference between the voltages of the liquid to be detected in the capillary at different positions and determining the electrolyte content in the user body according to the difference.
When wearing equipment has set up a plurality of capillaries, when detection module confirms the internal electrolyte content of user according to the difference, can be that the average difference of the voltage difference that the multiple capillaries correspond is worked out, confirms the internal electrolyte content of user according to the average difference. For example, assuming that the wearable device is provided with two capillaries, namely a first capillary and a second capillary, a difference value between voltages at different positions in the liquid to be detected in the first capillary is a first difference value U1, a difference value between voltages at different positions in the liquid to be detected in the second capillary is a second difference value U2, an average value of the first difference value U1 and the second difference value U2 is U1, and the detection module determines the electrolyte content in the user body according to the average difference value U1.
When wearing equipment has set up a capillary, for the accuracy that improves the detection, the inductive element is used for obtaining the voltage of measuring the liquid of waiting to detect at different positions many times at different moments to confirm the difference between the voltage of waiting to detect the liquid at different positions in the capillary at any moment, according to a plurality of differences, confirm the internal electrolyte content of user. Specifically, the detection module determines the electrolyte content in the user body according to a plurality of difference values, which may be an average value of the plurality of difference values. For example, assuming that the wearing device is provided with a capillary tube, the difference between the voltages at different positions of the capillary tube at the time T1 is a third difference U3, the difference between the voltages at different positions of the capillary tube at the time T2 is a fourth difference U4, and the average value of the third difference U3 and the fourth difference U4 is U2, the detection module determines the electrolyte content in the user body according to the average difference U2.
Optionally, the sensing element includes a first electrode and a second electrode, and the first electrode and the second electrode are respectively disposed at different positions in the axial direction of the capillary. Fig. 2 is a schematic structural diagram of the capillary and the sensing element provided in the present application, and as shown in fig. 2, the sensing element 21 includes a first electrode 211 and a second electrode 212, where the first electrode 211 and the second electrode 212 are respectively disposed at different axial positions of the capillary 12, and specifically, the electrodes can be implanted in the wall of the capillary by laser drilling on the capillary. The sensing element measures the voltage of the liquid to be detected at different positions through the first electrode 211 and the second electrode 212. The utility model provides a wearing equipment is when the collection waits to detect liquid, for improving the sample precision, improves the accuracy that detects user's internal electrolyte content, as shown in fig. 2, can set up first electrode 211 and second electrode 212 in the regional different positions in the middle part of capillary axial, makes the middle section liquid that waits to detect liquid that detects that gathers in the capillary between first electrode 211 and the second electrode 212.
When the first electrode 211 and the second electrode 212 are charged, the voltage difference between the two electrodes can be determined according to the voltages on the two electrodes because the liquid to be detected in the capillary is a conductive medium. Since the electrolyte content in sweat varies and its conductivity varies, resulting in a difference in resistance between the first electrode 211 and the second electrode 212, and a difference in voltage between the two electrodes varies, the electrolyte content in the user's body can be determined from the variation in voltage difference between the two electrodes.
To simplify the operation, optionally, the first electrode 211 is connected to the detection module, and the second electrode 212 is grounded. Based on the circuit, the detection module only needs to acquire the voltage of the first electrode 211, and the voltage difference between the first electrode 211 and the second electrode 212 can be obtained.
Optionally, the detection module includes a data processing unit, a resistor, and a capacitor; the first end of the resistor is respectively connected with the first end of the capacitor, the data processing unit and the first electrode, the second end of the resistor is connected with the power supply, and the second end of the capacitor is grounded. Fig. 3 is a schematic circuit diagram of a sensing assembly provided in the present application, which includes a detection module 31 and a sensing element 21. The detection module 31 comprises a data processing unit 310, a resistor 311 and a capacitor 312, the sensing element 21 comprises a first electrode 211 and a second electrode 212, and the first electrode 211 and the second electrode 212 are arranged at different positions in the axial direction of the capillary 12. A first end of the resistor 311 is connected to the data processing unit 310, the first electrode 211, and a first end of the capacitor 312; the second end of the resistor 311 is connected with the power supply; the second terminal of the capacitor 312 and the second electrode 212 are both grounded.
In this circuit, the capacitor 312 functions as a filter, and the resistor 311 functions as a voltage divider, so that it is possible to prevent the data processing module from being damaged due to an excessive voltage on the first electrode 211, and thus, the circuit also functions as a protection circuit. When the liquid to be detected is filled between the first electrode 211 and the second electrode 212, the first electrode 211 and the second electrode 212 are conducted, and since the second electrode 212 is grounded, the resistance between the first electrode 211 and the second electrode 212 and the resistance 311 form a voltage dividing circuit, assuming that the resistance between the first electrode 211 and the second electrode 212 is R1, the resistance of the resistance 311 is R2, the voltage on the first electrode 211 is U, and the power supply is VDD, equation (2) can be obtained:
when the electrolyte content in the liquid to be detected between the first electrode 211 and the second electrode 212 changes, the value of R1 changes, and further the voltage U changes, and the data processing module can determine the electrolyte content in the liquid to be detected according to the voltage U. For example, when sweat fills the space between the first electrode 211 and the second electrode 212, since the larger the content of sodium chloride in sweat is, the better the conductivity is, the smaller R1 is, the larger voltage U is; the smaller the sodium chloride content in the sweat is, the poorer the conductivity is, the larger R1 is, and the smaller voltage U is.
Further, the data processing module determines the electrolyte content in the liquid to be detected according to the voltage U, which may be determined by a pre-stored correspondence between the voltage and the electrolyte content in the liquid to be detected and an actually measured voltage value.
For example, assume that the pre-stored voltage in the data processing module corresponds to the content of sodium chloride in sweat, when the voltage U is between 0V and 2V, it indicates that the content of sodium chloride in sweat is low; when the voltage U is between 2V and 3V, the content of sodium chloride in the sweat is moderate; when the voltage U is between 3V and 5V, the content of sodium chloride in the sweat is high. Assuming that the voltage U actually measured by the data processing module is 2.5V, the content of sodium chloride in the sweat is moderate due to the fact that 2.5 is between 2V and 3V.
Optionally, the wearable device may further include a display module, the display module is disposed on the wearable device body, and the display module may be disposed on the front of the wearable device body for the user to check conveniently. The display module may be configured to display a prompt based on the electrolyte content, such as when the sensing assembly determines that the electrolyte content in the user's body is high, the display module displays "Please note that the loss of electrolyte is high! ". In order to improve the user experience, the display module may further push a corresponding prompt message to the user according to the electrolyte content, for example, when the sensing component determines that the electrolyte content in the user is high, the display module displays "please replenish moisture and electrolyte in time! ". Of course, the two display contents can be displayed simultaneously, so that the user can know not only the health condition of the user, but also the correct behavior to be made according to the health condition of the user.
Optionally, the wearable device may further include a voice prompt module, the voice prompt module is disposed on the wearable device body, and the voice prompt module may send different prompt messages according to the determined electrolyte content in the user body to prompt the user of the body state and/or prompt the user of the correct behavior to be made according to the health condition of the user.

When the wearable device is provided with the plurality of capillaries, the difference value of the voltages of the liquid to be detected in the capillaries at different positions is determined through the detection module, the average difference value of the voltage difference values corresponding to the plurality of capillaries can be obtained when the electrolyte content in the user body is determined according to the difference value, and the electrolyte content in the user body is determined according to the average difference value. For example, assuming that the wearable device is provided with two capillaries, namely a first capillary and a second capillary, a difference value between voltages at different positions in the liquid to be detected in the first capillary is a first difference value U1, a difference value between voltages at different positions in the liquid to be detected in the second capillary is a second difference value U2, an average value of the first difference value U1 and the second difference value U2 is U1, and the detection module determines the electrolyte content in the user body according to the average difference value U1.
When wearing equipment has set up a capillary, for the accuracy that improves the detection, can obtain the voltage of measuring the liquid of waiting to detect at different positions many times through response element at different moments to confirm the difference between the voltage of waiting to detect the liquid at different positions in the capillary at any moment, according to a plurality of differences, confirm the internal electrolyte content of user. Specifically, the detection module determines the electrolyte content in the user body according to a plurality of difference values, which may be an average value of the plurality of difference values. For example, assuming that the wearing device is provided with a capillary tube, the difference between the voltages at different positions of the capillary tube at the time T1 is a third difference U3, the difference between the voltages at different positions of the capillary tube at the time T2 is a fourth difference U4, and the average value of the third difference U3 and the fourth difference U4 is U2, the detection module determines the electrolyte content in the user body according to the average difference U2.
Optionally, after S402, in order to enhance the user experience, the method further includes S403, displaying a corresponding prompt message according to the electrolyte content.
Specifically, the prompt information corresponding to the electrolyte content may be displayed according to the electrolyte content and a mapping relationship stored in advance. Wherein the mapping relation is the mapping relation between at least one electrolyte content and at least one prompting message.
For example, when it is determined that the electrolyte content in the user's body is high, "Please note that the loss of electrolyte is high! ". In order to improve the user experience, the corresponding prompt information can be pushed to the user through the display module according to the electrolyte content, for example, when the sensing assembly determines that the electrolyte content in the user body is higher, the display module displays that the user is to please replenish water and electrolyte in time! ". Of course, the two display contents can be displayed simultaneously, so that the user can know not only the health condition of the user, but also the correct behavior to be made according to the health condition of the user.
The application also provides a computer-readable storage medium, wherein computer-executable instructions are stored in the computer-readable storage medium, and the computer-executable instructions are executed by a processor to realize the electrolyte content detection method.
The content and effect of the method for detecting the electrolyte content can be referred to in the embodiment of the method, and details are not repeated herein.
