[0032] FIG. 1 is a schematic structural diagram of a nursing care article according to an embodiment. The nursing care article includes an absorption part 101. As shown in FIG. 1, a humidity detection module for detecting the humidity value of the first position point set is installed in the absorption part 101. The first position point set includes at least one position point on the metabolite diffusion path of the absorption part 101. The metabolite detection method includes steps S110 to S120 as shown in FIG. 2.

[0033] In step S110, obtain the humidity value of the first position point set, and determine the increase state information representing the time-dependent increase situation of humidity at the position point based on the humidity value.

[0034] For better understanding, the first set of position points can include one or more position points where the absorption part 101 can come into contact with metabolites. Taking the multiple position points as an example, they may be located in the longitudinal direction of the absorption part 101, such as position points A, B, C, D, E, and F in the figure. The humidity detection module continuously detects the humidity value at the position points and can determine the increase state information at the position points based on the humidity value at the position points. The increase state information includes at least one of the humidity increase rate, the situation where the humidity value is maintained within a preset humidity range after the increase, and the maintenance time when the humidity value is maintained within the preset humidity range after the increase.

[0035] In step S120, determine the type of metabolite based on the increase state information. The types of metabolites include liquid metabolites and non - liquid metabolites.

[0036] Liquid metabolites can include urine or blood, and non - liquid metabolites can include solid metabolites and semi - solid metabolites. Solid metabolites are, for example, hard stools, and semi - solid metabolites are, for example, soft stools. When determining the type of metabolite, it can be determined based on the increase state information at one or more position points.

[0037] The absorption part 101 can be prepared from a flexible substrate, which may be materials such as PI, PET, nylon, non - woven fabric, etc. A conductive layer is prepared on the substrate. The conductive layer includes wires, pads, vias, electrodes, or electrical contacts, etc. The materials of the conductive layer include carbon, silver, copper, gold, etc. The thickness of the substrate is 0.05 - 0.3 mm. The substrate is in a long - strip shape, with a length of 100 mm - 300 mm and a width of 3 mm - 30 mm.

[0038] The embodiment of the present invention obtains the humidity values of the first set of position points detected by the humidity detection module, determines the increase state information at each position point in the first set of position points based on each humidity value, and then determines the type of metabolite based on the increase state information, with the method being simple and efficient.

[0039] In one embodiment, the increasing state information includes a humidity increase rate. As shown in FIG. 3, determining the type of metabolite based on the increasing state information includes step S121.

[0040] In step S121, when the humidity increase rate at at least one position point is greater than the increase rate threshold, it is determined that the type of metabolite is a liquid metabolite.

[0041] The increase rate threshold may be determined based on an empirical value of the humidity increase rate during the diffusion of the liquid metabolite in the absorption part 101, and may be, for example, the minimum value of the humidity increase rate during the diffusion of the liquid metabolite in the absorption part 101. As can be understood, since the absorption rate of the liquid metabolite by the absorption part 101 is fast, the humidity increase rate is also high. By setting the increase rate threshold, when the speed increase rate at a certain position point is greater than the increase rate threshold, it indicates that the liquid metabolite contacts the said position point.

[0042] In one embodiment, the increasing state information includes a maintenance time maintained within a preset humidity range after the humidity value is increased. The non - liquid metabolite includes a semi - solid metabolite. As shown in FIG. 4, determining the type of metabolite based on the increasing state information further includes step S122.

[0043] In step S122, when the maintenance time at at least one position point is greater than the first time threshold, it is determined that the type of metabolite is a semi - solid metabolite, and / or when the maintenance time at any position point is less than the second time threshold, it is determined that the metabolite is a liquid metabolite.

[0044] The semi-solid metabolite refers to feces with urine, and may be, for example, soft feces. As can be understood, the first time threshold may be determined based on the normal continuous urination time of the user, and may be, for example, longer than the longest urination time of the user. Since the liquid metabolite is quickly absorbed by the absorption part 101 after being discharged, its humidity may be maintained only in the case of continuous urination. However, since the semi-solid metabolite has a liquid such as urine and the urine therein is not quickly and completely absorbed by the absorption part 101, when the semi-solid metabolite is excreted at a certain position point, the humidity at that position point first increases rapidly, and when it reaches the peak, it is maintained in a certain humidity range for a long time. Thereby, when the maintenance time at at least one position point exceeds the first time threshold, that is, exceeds the normal urination time of the user, the maintenance of the humidity at that position point is not due to the urination situation, but rather due to the semi-solid metabolite. Therefore, at this time, it can be determined that the type of metabolite is a semi-solid metabolite. The change of the humidity of the semi-solid metabolite over time is shown in FIG. 10. Graph l1 is a time change graph, and graph l2 is a humidity value change graph of the semi-solid metabolite. In one embodiment, the first time threshold can be set based on an empirical value.

[0045] Therefore, the humidity at the position point is maintained for a certain period of time. The liquid metabolite may be, for example, urine, blood, etc. The second time threshold may be determined based on the normal continuous urination time of the user, and may be, for example, less than or equal to the longest urination time. As can be understood, since the liquid metabolite is quickly absorbed by the absorption part 101, the humidity value at the position point increases rapidly immediately after contacting the liquid metabolite. When there is no continuous liquid metabolite flowing at the position point, the humidity value at that position point immediately decreases. When the maintenance time at at least one position point is less than the first time threshold, that is, less than the normal urination time of the user, it indicates that the maintenance of the humidity at that position point is due to the urination situation. Therefore, at this time, it can be determined that the type of metabolite is a liquid metabolite. The change of the humidity of the liquid metabolite over time can be shown with reference to FIG. 11. Graph l3 is a time change graph, and graph l4 is a humidity value change graph of the liquid metabolite. The first time threshold and the second time threshold may be equal.

[0046] In one embodiment, the increasing state information includes a situation where the humidity value is maintained within a preset humidity range after being increased. In the absorption part 101 of the nursing care article, a temperature detection module for detecting the temperature value of the second set of position points is further installed. The second set of position points includes at least one common position point, and the common position point is a position point in the first set of position points. The non-liquid metabolite includes semi-solid metabolites. As shown in FIG. 5, the method further includes steps S130 to S140.

[0047] In step S130, the temperature value of the second set of position points is obtained.

[0048] As can be understood, the second set of position points can include one or more position points. Each position point is located on the metabolite diffusion path of the absorption part 101, and at least one position point at each position point is a position point in the first set of position points, that is, a common position point.

[0049] In step S140, when the increasing state information at at least one common position point satisfies a preset condition and the temperature value at the common position point gradually decreases, it is determined that the type of metabolite is a semi-solid metabolite. The preset condition is that the humidity value is maintained within a preset humidity range after being increased.

[0050] As can be understood, since the liquid metabolite is rapidly absorbed by the absorption part 101, its humidity value and temperature value rapidly decay after increasing. However, in the case of continuous excretion, its humidity value and temperature value are maintained within a certain range. Since the semi-solid metabolite is not rapidly absorbed, its humidity value is maintained within a certain range, but the temperature value gradually decreases. There may be the same position point at the position point detected by the humidity detection module and the position point detected by the temperature detection module. The said position point is a common position point. At the common position point, the humidity value and the temperature value are simultaneously acquired. When the common position point comes into contact with the metabolite, if its humidity value is maintained within a preset humidity range after increasing, it may be the case of continuously excreting the liquid metabolite or the metabolite being a semi-solid metabolite. At the same time, if its temperature value gradually decreases, the case of continuously excreting the liquid metabolite can be excluded, and it can be determined that the metabolite is a semi-solid metabolite. If its humidity value is maintained within a preset humidity range after increasing and the temperature value gradually decreases, it can be determined that the type of the metabolite is a semi-solid metabolite.

[0051] A temperature detection unit 102 may be installed in the temperature detection module. The temperature detection unit 102 may be prepared by processes such as printing, sputtering, and vapor deposition from a heat-sensitive material, and may be, for example, an NTC / PTC thermistor, a semiconductor temperature-sensitive chip, etc., and is prepared at a specified position by methods such as assembly, pasting, printing, and vapor deposition.

[0052] In one embodiment, the absorption part 101 of the nursing article is further provided with a temperature detection module that at least detects the temperature value at the first position point at the defecation position of the user. The first position point set includes at least the first position point. The non-liquid metabolite includes the solid metabolite. The method further includes steps S150 to S160 as shown in FIG. 6.

[0053] In step S150, the temperature value at the first position point is acquired. In step S160, when the temperature value at the first position point has a temperature increasing change and the humidity value at the first position point is less than the first humidity threshold, it is determined that the type of metabolite is a solid metabolite.

[0054] As can be understood, the first humidity threshold may be equal to or less than the maximum humidity value of the absorption part 101 when the solid metabolite is excreted to the absorption part 101. When the temperature value at the first position point has a temperature increasing change, it indicates that there is a metabolite at the first position point. At the same time, when the humidity value at the first position point is less than the first humidity threshold, it indicates that it is a solid metabolite, and the solid metabolite is, for example, dry feces.

[0055] In one embodiment, a temperature detection module for detecting the temperature values of the second position point set is further installed in the absorption part 101 of the nursing care article. The second position point set includes a plurality of position points on the absorption part 101 corresponding to each excretion position of the user in a state where the nursing care article is worn. As shown in FIG. 7, the method further includes steps S170 and S180.

[0056] In step S170, the temperature values of the second position point set are obtained, and based on the temperature values, temperature diffusion information representing the order when each position point has a temperature increasing change is determined.

[0057] As can be understood, the temperature detection module continuously collects the temperature values at each position point, and when a metabolite is excreted to the position point, the temperature at the position point rises. The temperature values at each position point are obtained, and based on the changes in each temperature value, the temperature increasing order at each position point, that is, the order in which metabolites enter each position point sequentially, is determined. That the position point has a temperature increasing change may mean that the temperature value at the position point exceeds the initial value. In order to improve the detection accuracy, that the position point has a temperature increasing change may mean that the temperature value at the position point exceeds the temperature threshold.

[0058] In step S180, the type of metabolite is determined based on the temperature diffusion information.

[0059] As can be understood, since the entry position points are different when different metabolites are excreted, and the position points through which the diffusion process flows are also different, it is possible to know the order in which each position point sequentially enters after the excretion of the metabolite based on the temperature diffusion information. Each position point corresponds one-to-one with each excretion site of the human body, and since the order at the position points through which different metabolites sequentially flow after excretion is different, the type of metabolite can be determined.

[0060] The temperature diffusion information can have a mapping relationship with the type of metabolite, and the type of the corresponding metabolite can be obtained based on the temperature diffusion information. The type of metabolite may include liquid metabolites such as urine, blood, etc., and may also include non-liquid metabolites such as solid feces and paste-like soft feces.

[0061] In one embodiment, as shown in FIG. 1, the second position point set includes the first position point A at the defecation position, the second position point B at the urination position of female users, and the third position point C at the urination position of male users. The distance between the second position point B and the first position point A is smaller than the distance between the third position point C and the first position point A. Determining the type of metabolite based on the temperature diffusion information includes step S181 as shown in FIG. 8.

[0062] In step S181, when the temperature diffusion information generates a rising temperature change one after another in the order of the third position point C, the second position point B, and the first position point A, or when the temperature diffusion information generates a rising temperature change one after another in the order of the second position point B, the first position point A, and the third position point C, it is determined that the type of metabolite is a liquid metabolite.

[0063] As can be understood, the third position point C is the position point at the urination position of male users. If the user is male, when urinating, urine first flows through the third position point C, the temperature of the third position point C rises, and diffuses to both ends. When diffusing in the direction of the feces excretion position, it sequentially flows through the second position point B and the first position point A, thereby causing the second position point B and the first position point A to generate a rising temperature change in sequence. Therefore, when a rising temperature change occurs one after another in the order of the third position point C, the second position point B, and the first position point A, it indicates that a male user has performed a liquid excretion act, and the metabolite may be urine.

[0064] The second position point B is the position point at the urination position of the female user. If the user is female, when urinating or during menstruation, the metabolite first flows through the second position point B, the temperature of the second position point B rises, and then diffuses to both ends. The distance between the first position point A and the second position point B is smaller than the distance between the third position point and the second position point B. Therefore, the first position point A contacts the metabolite earlier than the third position point C, and the first position point A generates a temperature rise change earlier than the third position point C. Therefore, when temperature rise changes occur successively in the order of the second position point B, the first position point A, and the third position point C, it indicates that the female user has the behavior of liquid excretion, and the metabolite may be urine or blood.

[0065] In one embodiment, the first position point set includes the first position point A at the defecation position, the second position point B at the urination position of the female user, and the third position point C at the urination position of the male user. The distance between the second position point B and the first position point A is smaller than the distance between the third position point C and the first position point A. Determining the type of metabolite based on the temperature diffusion information further includes step S182 as shown in FIG. 9.

[0066] In step S182, when the temperature diffusion information successively generates temperature rise changes in the order of the first position point A, the second position point B, and the third position point C, it is determined that the type of metabolite is a non-liquid metabolite.

[0067] As can be understood, the first position point A is the position point at the defecation position of the user. Regardless of whether the user is male or female, when excreting, the metabolite first flows through the first position point A, causing the temperature of the first position point A to rise and then diffuse to both ends. When diffusing in the direction of the user's urine position point, the second position point B and the third position point successively contact the metabolite and successively generate temperature rise changes. Therefore, when temperature rise changes occur successively in the order of the first position point A, the second position point B, and the third position point C, it indicates that the user has the behavior of non-liquid excretion, and the metabolite may be feces.

[0068] Based on the flow situation of metabolites in the nursing supplies during the excretion process of the user, a position point corresponding to the excretion part of the human body is set on the nursing supplies, and based on each position point, the type of excrement is determined in the order of contacting the excrement and generating a temperature rise change. The method is simple and the detection result is accurate.

[0069] In one embodiment, the diffusion rate of metabolites can be obtained based on the temperature value, and thereby it can also be determined whether it is a solid metabolite or a semi-solid metabolite based on the diffusion rate.

[0070] In one embodiment, when the type of metabolite is a liquid metabolite, the method further includes steps S210 and S220 as shown in FIG. 12.

[0071] In step S210, the humidity value of the second set of position points is obtained, and the metabolic amount of the liquid metabolite is determined based on the humidity value.

[0072] In step S220, when the metabolic amount exceeds the warning value, warning information is output.

[0073] As can be understood, in order to avoid the excessive accumulation of liquid metabolites in the nursing supplies, which affects the subsequent absorption effect of the nursing supplies and further affects the health of the user, the metabolic amount of the liquid metabolite can be further detected, and when it exceeds the set warning value, warning information for prompting the user to replace is output. The warning information may be an audio signal or display information.

[0074] In one embodiment, determining the metabolic amount of the liquid metabolite based on the humidity value includes steps S211 and S212.

[0075] In step S211, based on the humidity value, a target quantity which is the number of position points where the humidity value is greater than the second humidity threshold is determined.

[0076] In step S212, the metabolic amount is determined based on the target quantity.

[0077] For better understanding, when the humidity value at a position point is greater than the second humidity threshold, it indicates that there is a liquid metabolite at the position point. By reasonably setting the intervals between each position point, the number of position points in contact with the liquid metabolite and the metabolic amount correspond one-to-one, and thereby the corresponding metabolic amount can be obtained based on the number of position points.

[0078] As shown in FIG. 1, the first set of position points includes position points A, B, C, D, E, F, and G. Taking the example that the user is male, the penetration regions L1 to L4 are partitioned based on each position point, and the area of the penetration regions L1 to L4 increases sequentially. When only one position point is in contact with the liquid excrement, the liquid excrement is located within region L1, and the metabolic amount corresponding to region L1 may be 20 ml. When three position points are in contact with the liquid excrement, the liquid excrement is located within region L2, and the metabolic amount corresponding to region L2 may be 40 ml. Similarly, the metabolic amount corresponding to region L2 may be 40 ml, and the metabolic amount corresponding to region L4 may be 120 ml. The corresponding metabolic amount can be determined based on the target quantity. This method is simple and can effectively measure the metabolic amount.

[0079] In one embodiment, the first set of position points includes at least a target position point. The target position point includes at least one of the second position point B and the third position point C. The second position point is the position point at the urination position of a female user, and the third position point is the position point at the urination position of a male user. Determining the metabolic amount of the liquid metabolite based on the humidity value includes steps S213 and S214.

[0080] In step S213, the time interval between the increase time and the decrease time of the humidity value at the target position point is obtained. The increase time is the time when the increase rate of the humidity value at the target position point reaches the increase threshold, and the decrease time is the time when the decrease rate of the humidity value at the target position point reaches the decay threshold.

[0081] In step S214, the metabolic amount is obtained from the time interval and a preset excretion flow rate, where the preset excretion flow rate is the excretion volume of liquid metabolites per unit time.

[0082] As can be understood, in order to determine the metabolic amount, by obtaining the excretion time of the liquid metabolites during the user's excretion, the metabolic amount can be further determined in combination with the excretion volume per unit time. This can be achieved. The excretion time is the time interval between the time when the user starts excretion and the time when the user ends excretion. The time when the user starts excretion can be characterized by the time when the humidity value increases at the urine excretion position point. Since the liquid excrement is quickly absorbed after being discharged, when the excretion stops, the humidity value at the position point decreases. Therefore, the time when the excretion ends can be characterized by the time when the humidity value decreases at the urine excretion position point of the user. Because the humidity value at the increase time position point increases rapidly, it can be determined based on whether the increase rate of the humidity value at the target position point reaches the increase threshold value. The humidity value at the decrease time position point decays rapidly. Therefore, it can be determined based on whether the decrease rate reaches the decay threshold value. The collected humidity value can have a timestamp, and based on this, the increase time and the decrease time can be determined.

[0083] In one embodiment, the absorption part 101 is further provided with a component detection module for detecting metabolite component information at at least one position point on the metabolite diffusion path of the absorption part 101. The method further includes the steps of obtaining the metabolite component information and determining the type of metabolite based on the metabolite component information.

[0084] As can be understood, since the urea content in different metabolites is different, it is possible to determine whether it is a liquid metabolite or a non-liquid metabolite based on the urea content in the metabolite.

[0085] The component detection module may be installed at a position corresponding to the user's excretion site, or may be installed at other positions where it can contact the metabolite during the user's excretion process.

[0086] In one embodiment, in order to improve the accuracy of determination, generating a temperature increase change at each position point may be that the temperature value at each position point exceeds a temperature threshold value.

[0087] FIG. 13 is a schematic flowchart of a metabolite detection method according to another embodiment. Since its specific steps have been specifically described in the above embodiments, detailed description is omitted here.

[0088] The embodiments of the present invention further provide a nursing care article, including a humidity detection module and a detection module. The humidity detection module is installed in the absorption part 101 of the nursing care article for detecting the humidity values of the first position point set. The first position point set includes a plurality of position points on the metabolite diffusion path of the absorption part 101. The detection module acquires the humidity values of the first position point set, determines increase state information representing the temporal increase situation of humidity at the position point based on the humidity values, and determines the types of metabolites including liquid metabolites and non-liquid metabolites based on the increase state information.

[0089] The principle and beneficial effects of the nursing care article in this embodiment are similar to those of the embodiment of the metabolite detection method described above, so detailed description is omitted here.

[0090] In one embodiment, the first position point set includes at least two position point subsets. The distances between the position points in different position point subsets and the position point at the urine excretion position of the user are within different distance ranges. The humidity detection module includes a plurality of humidity detection units. The humidity sensing element constitutes at least two humidity detection modules. The humidity detection units in the same humidity detection module are connected in parallel. The humidity detection modules are respectively connected to the detection module and detect the humidity values of the position point subsets in a one-to-one correspondence.

[0091] As shown in FIG. 14, the second position point B subset includes position points A, B, C, D, E, F, and G. When determining the target quantity based on the humidity value and further determining the metabolic amount of the liquid metabolite, at least two detection networks are formed to reduce the complexity of the overall structure. Taking two detection networks as an example, that is, when the position points DCE are close to the excretion site and the humidity change is significant, one detection network is adopted. Since the position points ABFG are far from the excretion site and the humidity change may not be significant, another detection network is adopted. The humidity detection units 103 in the same detection network are connected in parallel, thereby reducing the complexity of the design structure. The humidity detection unit 103 includes one or more humidity-sensitive elements. When including a plurality of humidity-sensitive elements, the humidity-sensitive elements within the same humidity detection unit 103 can adopt a series connection, a parallel connection, or a combination of series and parallel connections. The humidity detection unit 103 may be a capacitive humidity detection unit 103 or a resistive humidity detection unit 103. In the case of a capacitive humidity detection unit 103, a parallel connection method is adopted, and in the case of a resistive humidity detection unit 103, a series connection method is adopted.

[0092] In one embodiment, the thermal detection element and the humidity detection unit 103 at the same position point may be integrated as a sensor unit to reduce the overall volume.

[0093] In one embodiment, the humidity detection module includes a plurality of first humidity detection units 103. The plurality of first humidity detection units 103 are respectively installed one-to-one at each position point in the first position point set. The sensitivity of each first humidity detection unit 103 is inversely proportional to the distance between the first humidity detection unit 103 and the position point at the user's urine excretion position.

[0094] As can be understood, as shown in FIG. 14, the humidity detection module may include only one row of the first humidity detection units 103, be located at the center of the absorption unit 101, detect the humidity values at each position point respectively, determine the target quantity based on the humidity values, and further determine the metabolic amount of the liquid metabolite. In order to reduce costs and reduce the complexity of the overall structure, the first humidity detection unit 103 with high sensitivity is adopted at the nearby urination position points, and the first humidity detection unit 103 with low sensitivity is adopted at the far urination position points. The first humidity detection unit 103 includes one or more humidity sensing elements. When including a plurality of humidity sensing elements, the humidity sensing elements within the same humidity detection unit 103 can adopt a series or parallel or a combination of series and parallel, and the sensitivity of the first humidity detection unit 103 can be adjusted by changing the number of humidity sensing elements.

[0095] In one embodiment, the humidity detection module further includes a plurality of groups of second humidity detection units 103, which are respectively connected to each first humidity detection unit 103 in a one-to-one manner. The straight line formed by the second humidity detection unit 103 corresponding to the first humidity detection unit 103 in the same group is perpendicular to the straight line where each first humidity detection unit 103 is located.

[0096] As can be understood, considering the case where the nursing supplies are worn unevenly, a plurality of groups of second humidity detection units 103 are installed, thereby forming a humidity detection unit 103 array. In this way, no matter which humidity unit detects the metabolite, the presence or absence of the excretion behavior can be accurately discriminated.

[0097] In one embodiment, the nursing care article further includes a temperature detection module. The temperature detection module is installed in the absorption part 101 that detects the temperature values of the second set of position points. The second set of position points includes a plurality of position points on the absorption part 101 corresponding to each excretion position of the user when the nursing care article is worn. The detection module further obtains the temperature values of the second set of position points and is used to determine temperature diffusion information based on the temperature values. The temperature diffusion information is used to represent the order when each position point generates a temperature rise change. The type of metabolite is determined based on the temperature diffusion information. The temperature detection module includes a plurality of temperature detection units 102, and each temperature detection unit 102 is respectively installed at each position point in the first set of position points in a one-to-one manner.

[0098] As shown in FIG. 14, temperature detection units 102 are respectively installed at the first position point A, the second position point B, and the third position point C in the first set of position points, and the temperature values at each position point are respectively detected. One temperature detection unit 102 can include one heat detection element or a plurality of heat detection elements. can be included.

[0099] In one embodiment, the temperature detection unit 102 includes a plurality of heat detection elements, and each heat detection element is connected in series or in parallel.

[0100] As can be understood, in order to improve the detection accuracy of the temperature detection unit 102, a plurality of heat detection elements can be installed to form the temperature detection unit 102, and the detection range can be widened to have a certain tolerance for the position of the metabolite. In order to improve the detection sensitivity, the heat detection element NTC of the negative temperature coefficient material selects parallel connection, and the heat detection element PTC of the positive temperature coefficient material selects series connection.

[0101] In one embodiment, the absorption part 101 includes a first base layer and a first siphon layer. The detection part of the humidity detection module is installed on the side of the first base layer close to the human body. The first siphon layer covers the detection part of the humidity detection module and absorbs and confines the liquid in the metabolite.

[0102] As can be understood, since the water-absorbing resin particles in the core material within the absorption part 101 of the nursing care product have a very strong water absorption effect, in order to ensure that sufficient moisture can reach the surface of the humidity detection unit 103, a first siphon layer is prepared on the electrode surface of the humidity detection unit 103 to trap moisture and guarantee the accuracy of detection. The first siphon layer can include a water-absorbing material (such as water-absorbing resin, polyurethane, foamed rubber, etc.).

[0103] In one embodiment, the nursing care product further includes a component detection module that is installed in the absorption part 101 and detects metabolite component information at at least one position point on the metabolite diffusion path of the absorption part 101. The detection module further obtains the metabolite component information and is used to determine the type of metabolite based on the metabolite component information. The component detection module includes a liquid phase detector and / or a gas phase detector.

[0104] When including a liquid phase detector, as shown in FIG. 15, the absorption part 101 further includes a second base layer 104 and a second siphon layer 107. The detection part 106 of the liquid phase detector is installed on the side of the second base layer 104 close to the human body. The second siphon layer 107 covers the detection part 106 of the liquid phase detector and is used to absorb and trap the liquid in the metabolite. 105 is the connection wiring of the liquid phase detector. The liquid substance to be detected includes at least one of, but is not limited to, pH value, glucose, dopamine, uric acid, ascorbic acid, galactose, ketone bodies, white blood cells, proteins, latent blood, K+ ions, Na+ ions, iodine ions, calcium ions, iron ions, zinc ions, nitrite, etc.

[0105] To be understandable, for liquid-phase component analysis, in order to ensure that there is sufficient urine in the reaction region within the detection time, it is necessary to establish a stable reaction region, thereby forming a part of the siphon passage. Otherwise, the urine will be sucked by the core material of the diaper and thus the demand for biochemical detection cannot be met. The second siphon layer 107 provides a stable reaction region, and urine enters the reaction region by siphon action and is detected by the detection element in the reaction region. The second siphon layer 107 can include a separator and a hydrophilic layer from bottom to top. Furthermore, the siphon passage inlet for liquid-phase component analysis can also be realized by making holes in the base layer, and the entire reaction region can also be realized with a polymer porous water-absorbing material.

[0106] When the component detection module includes a gas-phase detector, as shown in FIG. 16, the absorption part 101 further includes a third base layer 108 and a confinement layer 111. The detection part 110 of the gas-phase detector is installed on the side of the base layer close to the human body, and the confinement layer 111 covers the detection part 110 of the gas-phase detector and confines the gas in the metabolite. 109 is the connection wiring of the gas-phase detector and transmits the detection signal to the rear end. The gas-phase substances to be detected include at least one kind such as ammonia, hydrogen sulfide, hydrogen, and skatole, but are not limited thereto. Also, in order to avoid physical scratches on the confinement layer 111 caused by external substances, the confinement layer 111 can also be covered with a protective film layer. The above base layer is a carrier for the detection part and the connection wiring.
