[0032] Figure 1 is a schematic diagram of a nursing care product according to one embodiment, and the nursing care product includes an absorbent part 101, and as shown in Figure 1, the absorbent part 101 is equipped with a humidity detection module that detects the humidity value of a first set of location points, the first set of location points includes at least one location point in the metabolite diffusion pathway of the absorbent part 101, and the metabolite detection method includes steps S110 to S120, as shown in Figure 2.

[0033] In step S110, the humidity values ​​of the first set of location points are obtained, and based on the humidity values, increase state information representing the time-dependent increase in humidity at each location point is determined.

[0034] To make it clear, the first set of location points may include one or more location points positioned so that the absorbent unit 101 can come into contact with metabolites. For example, multiple location points may be located along the longitudinal direction of the absorbent unit 101, such as location points A, B, C, D, E, and F in the figure. The humidity detection module continuously detects the humidity value at the location point and can determine the increase state information at the location point based on the humidity value at the location point. The increase state information includes at least one of the humidity increase rate, the condition under which the humidity value is maintained within a preset humidity range after it has increased, and the duration for which the humidity value is maintained within a preset humidity range after it has increased.

[0035] In step S120, the type of metabolite is determined based on the increase status information, and the type of metabolite includes liquid metabolites and non-liquid metabolites.

[0036] Liquid metabolites may include urine or blood, while non-liquid metabolites may include solid and semi-solid metabolites. Solid metabolites are, for example, hard stool, and semi-solid metabolites are, for example, soft stool. The type of metabolite can be determined based on increasing status information at one or more locations.

[0037] The absorbent portion 101 can be prepared from a flexible substrate, which may be a material such as PI, PET, nylon, or nonwoven fabric. A conductive layer is prepared on the substrate, and the conductive layer includes wires, pads, vias, electrodes, or electrical contacts. The material of the conductive layer includes carbon, silver, copper, or gold. The thickness of the substrate is 0.05 to 0.3 mm, and the substrate is elongated, with a length of 100 mm to 300 mm and a width of 3 mm to 30 mm.

[0038] In this embodiment of the present invention, humidity values ​​for a first set of location points detected by a humidity detection module are acquired, and based on each humidity value, the increase state information at each location point in the first set of location points is determined. Based on the increase state information, the type of metabolite is determined, and the method is simple and efficient.

[0039] In one embodiment, the increase state information includes the humidity increase rate, and as shown in Figure 3, determining the type of metabolite based on the increase state information includes step S121.

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

[0041] The rate of increase threshold may be determined based on empirical values ​​of the rate of humidity increase during the diffusion of liquid metabolites in the absorption section 101, for example, it may be the minimum value of the rate of humidity increase during the diffusion of liquid metabolites in the absorption section 101. As can be understood, because the absorption rate of liquid metabolites by the absorption section 101 is fast, the rate of humidity increase is also high, and by setting a rate of increase threshold, it is indicated that if the rate of velocity increase at a certain point is greater than the rate of increase threshold, the liquid metabolites will come into contact with that point.

[0042] In one embodiment, the increase state information includes the maintenance time during which the humidity value is maintained within a preset humidity range after it has increased, and the non-liquid metabolites include semi-solid metabolites, and the determination of the type of metabolite based on the increase state information, as shown in Figure 4, further includes step S122.

[0043] In step S122, if the maintenance time at at least one location is greater than the first time threshold, the type of metabolite is determined to be a semi-solid metabolite, and / or if the maintenance time at either location is less than the second time threshold, it is determined to be a liquid metabolite.

[0044] Semi-solid metabolites refer to feces contaminated with urine, and may include, for example, loose stools. To make it clear, the first time threshold may be determined based on the user's normal continuous urination time, for example, it may be longer than the user's longest urination time. Since liquid metabolites are rapidly absorbed into the absorbent unit 101 after excretion, their humidity may only be maintained in the case of continuous urination. However, because semi-solid metabolites contain liquid such as urine, and the urine within them is not rapidly and completely absorbed into the absorbent unit 101, when semi-solid metabolites are excreted at a certain location, the humidity at that location first increases rapidly, and once it reaches a peak, it is maintained in a certain humidity range for a long time. As a result, if the maintenance time at at least one location exceeds the first time threshold, i.e., exceeds the user's normal urination time, the maintenance of humidity at that location is not due to the urination situation, but rather to the semi-solid metabolites, and at this time, it can be determined that the type of metabolite is a semi-solid metabolite. Figure 10 shows the change in humidity of semi-solid metabolites over time, with graph l1 being a time-dependent graph and graph l2 being a graph of the change in humidity value of semi-solid metabolites. In one embodiment, the first time threshold can be set based on empirical values.

[0045] To achieve this, the humidity at the location is maintained for a certain period of time. The liquid metabolite may be, for example, urine or blood. The second time threshold may be determined based on the user's normal continuous urination time, for example, it may be less than or equal to the longest urination time. As can be understood, since the liquid metabolite is rapidly absorbed by the absorption unit 101, the humidity value at the location increases rapidly immediately after contact with the liquid metabolite. If there is no continuous flow of liquid metabolite at the location, the humidity value at the location decreases immediately. If the maintenance time at at least one location is less than the first time threshold, i.e., less than the user's normal urination time, it indicates that the maintenance of humidity at that location is due to the urination situation, and therefore, it can be determined that the type of metabolite is a liquid metabolite. The change in humidity of the liquid metabolite over time can be shown by referring to Figure 11, where graph l3 is a time change graph and graph l4 is a graph of the change in humidity value 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 in which the humidity value is maintained within a preset humidity range after it has increased, the absorbent part 101 of the care product is further equipped with a temperature detection module that detects the temperature value of a second set of position points, the second set of position points includes at least one common position point, the common position point is a position point in the first set of position points, the non-liquid metabolites include semi-solid metabolites, and the method further includes steps S130 to S140 as shown in Figure 5.

[0047] In step S130, the temperature values ​​of the second set of location points are obtained.

[0048] To make it clear, the second set of location points may include one or more location points, each location point located on the metabolite diffusion pathway of the absorption unit 101, and at least one location point at each location point is a location point in the first set of location points, i.e., a common location point.

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

[0050] As can be understood, liquid metabolites are rapidly absorbed by the absorption unit 101, so their humidity and temperature values ​​increase and then rapidly decay, but in the case of continuous excretion, their humidity and temperature values ​​are maintained within a certain range, and semi-solid metabolites are not rapidly absorbed, so their humidity value is maintained within a certain range, but their temperature value gradually decreases. There may be the same location point detected by the humidity detection module and the location point detected by the temperature detection module, and such location point is a common location point, and the humidity and temperature values ​​are acquired simultaneously at the common location point, and when the common location point comes into contact with a metabolite, if the humidity value increases and then is maintained within a preset humidity range, it may be the case that liquid metabolites are being continuously excreted or that the metabolites are semi-solid metabolites, and if the temperature value is gradually decreasing at the same time, the case of continuous excretion of liquid metabolites can be ruled out and it can be determined that the metabolites are semi-solid metabolites. If the humidity value increases and then is maintained within a preset humidity range and the temperature value gradually decreases, it can be determined that the type of metabolite is a semi-solid metabolite.

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

[0052] In one embodiment, the absorbent part 101 of the care product is further equipped with a temperature detection module that detects at least the temperature value at a first position point at the user's defecation location, the first position point set includes at least the first position point, the non-liquid metabolites include solid metabolites, and the method further includes steps S150 to S160 as shown in Figure 6.

[0053] In step S150, the temperature value at the first position is obtained. In step S160, if the temperature value at the first location has increased and the humidity value at the first location is less than the first humidity threshold, it is determined that the type of metabolite is a solid metabolite.

[0054] To make it easier to understand, the first humidity threshold may be less than or equal to the maximum humidity value of the absorption unit 101 when solid metabolites are excreted into the absorption unit 101. When the temperature value at the first location undergoes a temperature increase, it indicates that metabolites are present at the first location, and at the same time, when the humidity value at the first location is less than the first humidity threshold, it indicates that solid metabolites are present, such as dry feces.

[0055] In one embodiment, the absorbent portion 101 of the care product is further equipped with a temperature detection module for detecting the temperature of a second set of position points, the second set of position points includes a plurality of position points on the absorbent portion 101 corresponding to each excretion position of the user when the care product is worn, and the method further includes steps S170 and S180 as shown in Figure 7.

[0056] In step S170, the temperature values ​​of the second set of location points are obtained, and based on the temperature values, temperature diffusion information is determined that represents the order in which each location point undergoes a temperature increase.

[0057] To make it easier to understand, the temperature detection module continuously collects temperature values ​​at each location, and the temperature at a location rises when metabolites are excreted there. The temperature value at each location is acquired, and based on the change in each temperature value, the sequence of temperature rise at each location, i.e., the order in which metabolites enter each location sequentially, is determined. A temperature rise at a location may occur when the temperature value at that location exceeds the initial value, or, to improve detection accuracy, a temperature rise at a location may occur when the temperature value at that location exceeds a temperature threshold.

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

[0059] To make it easier to understand, different metabolites enter different locations during excretion, and they also flow through different locations during the diffusion process. Therefore, based on temperature diffusion information, the order in which metabolites enter each location sequentially after excretion can be determined. Each location corresponds one-to-one with each excretory site in the human body, and the different order in which different metabolites flow through these locations after excretion allows for the determination of the type of metabolite.

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

[0061] In one embodiment, as shown in Figure 1, the second set of position points includes a first position point A at the defecation position, a second position point B at the urination position of a female user, and a third position point C at the urination position of a male user, where 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, and determining the type of metabolite based on temperature diffusion information includes step S181, as shown in Figure 8.

[0062] In step S181, if the temperature diffusion information indicates that the temperature increases sequentially in the order of third position C, second position B, and first position A, or in the order of second position B, first position A, and third position C, then the type of metabolite is determined to be a liquid metabolite.

[0063] To make it easier to understand, the third position C is the position at the urination site for male users. If the user is male, when urinating, urine first flows through the third position C, causing its temperature to rise. Then it diffuses to both ends and, as it diffuses towards the defecation site, it flows sequentially through the second position B and the first position A. This causes the second position B and the first position A to undergo a temperature increase in sequence. Therefore, if the temperature increases occur in the order of the third position C, the second position B, and the first position A, it indicates that the male user is performing the act of liquid excretion, and the metabolite may be urine.

[0064] The second position B is the position at the urination site of a female user. If the user is female, metabolites will first flow through the second position B during urination or menstruation, causing the temperature of the second position B to rise and then diffuse to both ends. The distance between the first position A and the second position B is smaller than the distance between the third position and the second position B. Therefore, the first position A comes into contact with the metabolites before the third position C, and the first position A experiences a temperature increase before the third position C. Thus, if temperature increases occur successively in the order of the second position B, the first position A, and the third position C, it indicates that the female user is performing the act of liquid excretion, and the metabolites may be urine or blood.

[0065] In one embodiment, the first set of position points includes a first position point A at the defecation position, a second position point B at the urination position of a female user, and a third position point C at the urination position of a male user, wherein 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, and determining the type of metabolite based on temperature diffusion information further includes step S182, as shown in Figure 9.

[0066] In step S182, if the temperature diffusion information indicates that a temperature increase occurs successively in the order of first position A, second position B, and third position C, then the type of metabolite is determined to be a non-liquid metabolite.

[0067] To make it easier to understand, the first position A is the position at the user's defecation location. Regardless of whether the user is male or female, when the user defecates, the metabolites first flow through the first position A, causing the temperature at the first position A to rise. As the metabolites diffuse to both ends and towards the user's urination location, the second position B and the third position C come into contact with the metabolites at the second position B in succession, causing successive temperature increases. Therefore, if temperature increases occur in the order of the first position A, second position B, and third position C, it indicates that the user is performing a non-liquid excretion act, and the metabolites may be feces.

[0068] The above embodiment involves placing points on the care product corresponding to the excretory site of the human body, based on the flow of metabolites to the care product during the user's excretion process. Based on these points, the type of excretion is determined by contacting the excrement and the order in which temperature changes occur. The method is simple and the detection results are accurate.

[0069] In one embodiment, the diffusion rate of a metabolite can be obtained based on the temperature value, thereby determining whether it is a solid or 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 Figure 12.

[0071] In step S210, the humidity value of the second set of location points is obtained, and the metabolic rate of liquid metabolites is determined based on the humidity value.

[0072] In step S220, if the metabolic rate exceeds the warning value, a warning message is output.

[0073] To ensure clarity, and to prevent excessive accumulation of liquid metabolites from care products, which can affect subsequent absorption and further impact the user's health, the metabolic rate of liquid metabolites can be further detected. If the set warning level is exceeded, a warning message prompting the user to replace the product is output. The warning message may be an audio signal or a display.

[0074] In one embodiment, determining the metabolic rate of liquid metabolites based on humidity values ​​includes steps S211 and S212.

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

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

[0077] To make it easier to understand, if the humidity value at a location is greater than the second humidity threshold, it indicates the presence of liquid metabolites at that location. By rationally setting the intervals between each location, there is a one-to-one correspondence between the number of locations in contact with liquid metabolites and the amount of metabolites, thereby allowing us to obtain the corresponding amount of metabolites based on the number of locations.

[0078] As shown in Figure 1, the first set of position points includes position points A, B, C, D, E, F, and G, and assuming the user is male, the infiltration areas L1 to L4 are partitioned based on each position point, and the area of ​​the infiltration areas L1 to L4 increases sequentially. If only one position point is in contact with the liquid excrement, the liquid excrement is located within area L1, and the metabolic amount corresponding to area L1 may be 20 ml. If three position points are in contact with the liquid excrement, the liquid excrement is located within area L2, and the metabolic amount corresponding to area L2 may be 40 ml. Similarly, the metabolic amount corresponding to area L2 may be 40 ml, and the metabolic amount corresponding to area L4 may be 120 ml. The corresponding metabolic amount can be determined based on the target quantity, and this method is simple and allows for effective measurement of metabolic amounts.

[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 being a position point at the urination position of a female user, and the third position point being a position point at the urination position of a male user, and determining the amount of liquid metabolites metabolized based on humidity values ​​includes steps S213 and S214.

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

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

[0082] To make it easier to understand, in order to determine the metabolic rate, the metabolic rate is further determined by obtaining the excretion time of liquid metabolites during the user's excretion, in conjunction with the volume of excretion per unit time. This is possible. The excretion time is the time interval between the time when the user starts excreting and the time when they finish excreting. The time when excretion starts can be characterized by the time when the humidity value at the user's urination location increases. Since liquid excrement is absorbed quickly after it is expelled, when excretion stops, the humidity value at the location decreases. Therefore, the time when excretion ends can be characterized by the time when the humidity value at the user's urination location decreases. At the time of increase, the humidity value at the location increases rapidly, so it can be determined based on whether the rate of increase of the humidity value at the target location has reached an increase threshold. At the time of decrease, the humidity value decreases rapidly, so it can be determined based on whether the rate of decrease has reached an decrease threshold. The collected humidity values ​​may have a timestamp, and the time of increase and the time of decrease can be determined based on that.

[0083] In one embodiment, the absorption unit 101 is further equipped with a component detection module that detects metabolite component information at at least one location on the metabolite diffusion pathway of the absorption unit 101, and the method further includes the steps of acquiring metabolite component information and determining the type of metabolite based on the metabolite component information.

[0084] To make it easier to understand, different metabolites contain different amounts of urea, so it is possible to determine whether a metabolite is a liquid or non-liquid metabolite based on its urea content.

[0085] The component detection module may be installed in a location corresponding to the user's excretory site, or in another location where it can come into contact with metabolites during the user's excretory process.

[0086] In one embodiment, in order to improve the accuracy of the determination, the temperature increase at each location may be caused by the temperature value at each location exceeding a temperature threshold.

[0087] Figure 13 is a schematic flowchart of a metabolite detection method in another embodiment. The specific steps were described in detail in the above embodiment, so a detailed explanation is omitted here.

[0088] Embodiments of the present invention further provide a care product comprising a humidity detection module and a detection module, the humidity detection module being installed in the absorbent section 101 of the care product for detecting humidity values ​​of a first set of location points, the first set of location points comprising a plurality of location points in the metabolite diffusion pathway of the absorbent section 101, the detection module acquiring humidity values ​​of the first set of location points, determining increase state information that represents the rate of increase in humidity over time at the location points based on the humidity values, and determining the type of metabolites, including liquid metabolites and non-liquid metabolites, based on the increase state information.

[0089] The principle and beneficial effects of the caregiving product in this embodiment are similar to those of the metabolite detection method described above, so a detailed explanation is omitted here.

[0090] In one embodiment, the first set of location points includes at least two sets of location point subsets, and the distances between location points in different sets of location point subsets and location points at the user's urination location are within different distance ranges. The humidity detection module includes a plurality of humidity detection units, and the humidity sensing elements constitute at least two humidity detection modules, with humidity detection units within the same humidity detection module connected in parallel. Each humidity detection module is connected to a detection module, and each detects the humidity values ​​of the set of location point subsets in a one-to-one correspondence.

[0091] As shown in Figure 14, the second set of location points B includes location points A, B, C, D, E, F, and G. When determining the target quantity based on humidity values ​​and further determining the metabolic rate of liquid metabolites, at least two detection networks are formed to reduce the complexity of the overall structure. As an example of two detection networks, if location point DCE is close to the excretion site and humidity changes are significant, one detection network is employed, and if location points ABFG are close to the excretion site Because humidity changes may not be significant at a distance, another detection network is employed, and 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 sensing elements, and if it includes multiple humidity sensing elements, the humidity sensing elements in the same humidity detection unit 103 can be in series, parallel, or a combination of series and parallel. The humidity detection unit 103 may be a capacitive humidity detection unit 103 or a resistive humidity detection unit 103, and 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 heat detection element and humidity detection unit 103 located at the same position 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, each of which is installed one-to-one at each position in a first set of position points, and 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 urination location.

[0094] To make it easier to understand, as shown in Figure 14, the humidity detection module may include only one row of first humidity detection units 103, which are located in the center of the absorption section 101 and detect the humidity value at each location. When determining the target quantity based on the humidity value and further determining the metabolic rate of liquid metabolites, in order to reduce costs and the complexity of the overall structure, a first humidity detection unit 103 with high sensitivity is used at nearby urination locations, and a first humidity detection unit 103 with low sensitivity is used at distant urination locations. The first humidity detection unit 103 includes one or more humidity-sensing elements. If it includes multiple humidity-sensing elements, the humidity-sensing elements within the same humidity detection unit 103 can be arranged in series, parallel, or a combination of series and parallel. 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, each connected one-to-one with each first humidity detection unit 103, and the line formed by the second humidity detection units 103 of the same group and the corresponding first humidity detection units 103 is orthogonal to the line in which each first humidity detection unit 103 is located.

[0096] To facilitate understanding, and considering cases where caregiving equipment is worn unevenly, multiple groups of second humidity detection units 103 may be installed to form a humidity detection unit 103 array, thereby enabling accurate determination of whether or not excretion has occurred regardless of which humidity unit detects metabolites.

[0097] In one embodiment, the care product further includes a temperature detection module, which is installed on an absorbent unit 101 that detects the temperature values ​​of a second set of position points, the second set of position points includes a plurality of position points on the absorbent unit 101 corresponding to each excretion position of the user when the care product is worn, the detection module further acquires 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 in which each position point undergoes a temperature increase change, the type of metabolite is determined based on the temperature diffusion information, and the temperature detection module includes a plurality of temperature detection units 102, each of which is installed one-to-one with each position point in the first set of position points.

[0098] As shown in Figure 14, temperature detection units 102 are installed at the first position A, second position B, and third position C in the first set of position points, and the temperature value at each position point is detected. Each temperature detection unit 102 has one thermal sensing element or multiple thermal sensing elements. It can include...

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

[0100] To improve the detection accuracy of the temperature sensing unit 102, multiple thermal sensing elements may be installed to configure the temperature sensing unit 102, widening the detection range and providing some tolerance to the location of metabolites. To improve detection sensitivity, thermal sensing elements NTC made of negative temperature coefficient material are selected in parallel, and thermal sensing elements PTC made of positive temperature coefficient material are selected in series.

[0101] In one embodiment, the absorption section 101 includes a first base layer and a first siphon layer, the detection unit of the humidity detection module is installed on the side of the first base layer closest to the human body, and the first siphon layer covers the detection unit of the humidity detection module and absorbs and contains liquid in the metabolites.

[0102] To ensure accuracy of detection, the water-absorbing resin particles in the core material within the absorbent section 101 of the care product have a very strong water-absorbing effect. Therefore, to ensure that sufficient moisture reaches 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 the moisture and ensure detection accuracy. The first siphon layer may include a water-absorbing material (e.g., water-absorbing resin, polyurethane, foamed rubber, etc.).

[0103] In one embodiment, the care product further includes a component detection module installed in the absorbent section 101 for detecting metabolite component information at at least one location on the metabolite diffusion pathway of the absorbent section 101, the detection module further being used to acquire metabolite component information and determine the type of metabolite based on the metabolite component information, and the component detection module includes a liquid-phase detector and / or a gas-phase detector.

[0104] When a liquid-phase detector is included, as shown in Figure 15, the absorption unit 101 further includes a second base layer 104 and a second siphon layer 107, the detection unit 106 of the liquid-phase detector is installed on the side of the second base layer 104 closer to the human body, the second siphon layer 107 covers the detection unit 106 of the liquid-phase detector and is used to absorb and contain the liquid in metabolites, and 105 is the connection wiring of the liquid-phase detector. The liquid to be detected includes, but is not limited to, at least one of the following: pH value, glucose, dopamine, uric acid, ascorbic acid, galactose, ketone bodies, leukocytes, proteins, saphenous blood, K+ ions, Na+ ions, iodide ions, calcium ions, iron ions, zinc ions, nitrites, etc.

[0105] To understand that liquid-phase component analysis requires the establishment of a stable reaction region to ensure sufficient urine in the reaction region within the detection time, thereby forming part of the siphon passage; otherwise, the urine would be aspirated by the core material of the diaper, thus failing to meet the demands of biochemical detection. The second siphon layer 107 provides a stable reaction region, allowing urine to enter the reaction region via siphon action and be detected by the detection element in the reaction region. The second siphon layer 107 may 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 creating a hole in the base layer, and the entire reaction region may be realized with a polymer porous water-absorbing material.

[0106] When the component detection module includes a gas-phase detector, as shown in Figure 16, the absorption section 101 further includes a third base layer 108 and a containment layer 111, the detection unit 110 of the gas-phase detector is installed on the side of the base layer closest to the human body, and the containment layer 111 covers the detection unit 110 of the gas-phase detector and contains the gas in the metabolites. 109 is the connection wiring for the gas-phase detector, which transmits the detection signal to the rear end. The gas-phase detected substances include ammonia, hydrogen sulfide, hydrogen, skatole, and many others. This includes, but is not limited to, one type. Furthermore, to avoid physical scratching of the containment layer 111 by external materials, the containment layer 111 can be covered with a protective film layer. The above-mentioned base layer serves as a carrier for the detection unit and connecting wiring.
