[0088] Figure 1 is a structural schematic diagram of a nursing product according to an embodiment. The nursing product includes an absorption portion 101. As shown in Figure 1, the absorption portion 101 is provided with a humidity sensing module for sensing the humidity value of a first position point set, wherein the first position point set includes at least one position point located on a metabolite diffusion path of the absorption portion 101. The metabolite detection method includes steps S110 to S120, as shown in Figure 2.

[0089] Step S110 , obtaining humidity values ​​of a first set of location points, and determining growth status information of the location points according to the humidity values, where the growth status information is used to characterize the growth of humidity at the location points over time.

[0090] It can be understood that the first position point set may include one or more position points, which are arranged at the position where the absorption part 101 can contact the metabolites. Taking multiple position points as an example, they can be located in the length direction of the absorption part 101, such as position points A, B, C, D, E, and F in the figure. The humidity sensing module can continuously sense the humidity value of the position point, and the growth status information of the position point can be determined based on the humidity value of the position point. The growth status information may include at least one of the humidity growth rate, the situation in which the humidity value remains within the preset humidity range after increasing, and the maintenance time of the humidity value within the preset humidity range after increasing.

[0091] Step S120 : determining the metabolite type according to the growth state information, wherein the metabolite type includes liquid metabolites and non-liquid metabolites.

[0092] Liquid metabolites may include urine or blood, and non-liquid metabolites may include solid metabolites and semi-solid metabolites. Solid metabolites may be, for example, hard stool, and semi-solid metabolites may be, for example, loose stool. When determining the type of metabolite, the determination may be made based on the growth status information of one or more locations.

[0093] The absorbent portion 101 can be made of a flexible substrate such as PI, PET, nylon, or non-woven fabric. The substrate is provided with a conductive layer comprising conductive wires, pads, vias, electrodes, or electrical contacts. The conductive layer is made of materials such as carbon, silver, copper, and gold. The substrate has a thickness of 0.05 to 0.3 mm and is in the form of a long strip, ranging from 100 mm to 300 mm in length and 3 mm to 30 mm in width.

[0094] The embodiment of the present invention obtains the humidity value of the first position point set sensed by the humidity sensing module, and determines the growth status information of each position point in the first position point set according to each humidity value, thereby determining the metabolite type according to the growth status information. The method is simple and effective.

[0095] In one embodiment, the growth status information includes a humidity growth rate, and determining the metabolite type according to the growth status information includes step S121 , as shown in FIG3 .

[0096] Step S121 : If the humidity growth rate of at least one location point is greater than a rate threshold, the metabolite type is determined to be a liquid metabolite.

[0097] The rate threshold can be determined based on an empirical value of the humidity growth rate of liquid metabolites as they diffuse within the absorbent portion 101. For example, it can be the minimum value of the humidity growth rate of liquid metabolites as they diffuse within the absorbent portion 101. It will be appreciated that the faster the absorbent portion 101 absorbs liquid metabolites, the higher the humidity growth rate. By setting a rate threshold, if the velocity growth rate at a location exceeds the rate threshold, it indicates that the location has come into contact with liquid metabolites.

[0098] In one embodiment, the growth status information includes the maintenance time of the humidity value within the preset humidity range after the humidity value increases, the non-liquid metabolite includes a semi-solid metabolite, and determining the metabolite type according to the growth status information further includes step S122, as shown in Figure 4.

[0099] Step S122: if the holding time of at least one point is greater than the first time threshold, the metabolite type is determined to be a semi-solid metabolite; and / or if the holding time of any point is less than the second time threshold, the metabolite type is determined to be a liquid metabolite.

[0100] Among them, semi-solid metabolites refer to stool containing urine, such as loose stools. It is understood that the first time threshold can be determined based on the user's usual continuous urination time, for example, it can be greater than or equal to the user's longest urination time. Since liquid metabolites are quickly absorbed by the absorption portion 101 after being discharged, their humidity can only be maintained during continuous urination. However, since semi-solid metabolites contain liquids such as urine, and the urine within them is not quickly absorbed by the absorption portion 101, when semi-solid metabolites are excreted at a certain location, the humidity at that location will first increase sharply, reaching a peak and then remaining within a certain humidity range for a long time. Accordingly, if the maintenance time of at least one location exceeds the first time threshold, that is, exceeds the user's normal urination time, it indicates that the maintenance of humidity at that location is not caused by urination, but by semi-solid metabolites. Therefore, the metabolite type can be determined as semi-solid metabolites. The change in humidity of semi-solid metabolites over time can be seen in Figure 10, where curve l1 is the time change curve and curve l2 is the change curve of the humidity value of the semi-solid metabolites. In one embodiment, the first time threshold may be set according to an empirical value.

[0101] Among them, the humidity of the location point will be maintained for a period of time.

[0102] Liquid metabolites can be, for example, urine, blood, etc. The second time threshold can also be determined based on the user's typical duration of urination, for example, it can be less than or equal to the maximum urination time. It is understood that liquid metabolites can be rapidly absorbed by the absorbent portion 101, so the humidity value at a location will increase sharply upon contact with the liquid metabolite. When there is no continuous liquid metabolite flow through the location, the humidity value at the location will quickly decrease. If the maintenance time of at least one location is less than the first time threshold, that is, less than the user's normal urination time, it can be indicated that the humidity at the location is maintained due to urination. Therefore, the metabolite type can be determined to be liquid metabolite. The change in humidity of the liquid metabolite over time can be shown in Figure 11, where curve 13 is the time change curve and curve 14 is the change curve of the humidity value of the liquid metabolite. The first time threshold and the second time threshold can be equal.

[0103] In one embodiment, the growth status information includes the situation where the humidity value is maintained within a preset humidity range after increasing. The absorption part 101 of the care product is also provided with a temperature sensing module for sensing the temperature value of a second position point set. The second position point set includes at least one common position point, which is a position point in the first position point set. The non-liquid metabolite includes a semi-solid metabolite. The method also includes steps S130 to S140, as shown in Figure 5.

[0104] Step S130: Acquire temperature values ​​of the second location point set.

[0105] It can be understood that the second position point set may include one or more position points, each of which is located on the metabolite diffusion path of the absorption part 101, and at least one of the position points is a position point in the first position point set, that is, a common position point.

[0106] Step S140: If the growth status information of at least one common location point meets a preset condition and the temperature value of the common location point gradually decreases, the metabolite type is determined to be a semi-solid metabolite; wherein the preset condition is that the humidity value remains within a preset humidity range after increasing.

[0107] It can be understood that liquid metabolites are rapidly absorbed by the absorption portion 101, so their humidity and temperature values ​​increase and then rapidly decay. However, when excretion is continuous, their humidity and temperature values ​​can be maintained within a certain range. Semi-solid metabolites cannot be rapidly absorbed, so their humidity value remains within a certain range, while their temperature value gradually decreases. The location points sensed by the humidity sensing module and the location points sensed by the temperature sensing module may exist at the same location point, which is a common location point. The common location point simultaneously obtains humidity and temperature values. When the common location point contacts metabolites, if its humidity value increases and then remains within the preset humidity range, it may be a case of continuous excretion of liquid metabolites or the metabolite is a semi-solid metabolite. At the same time, if its temperature value gradually decreases, it can be ruled out as continuous excretion of liquid metabolites, and the metabolite can be determined to be a semi-solid metabolite. If its humidity value increases and then remains within the preset humidity range, and its temperature value gradually decreases, it can be determined that the metabolite type is a semi-solid metabolite.

[0108] The temperature sensing module can be provided with a temperature sensing unit 102. The temperature sensing unit 102 can be prepared by a thermosensitive material through printing, sputtering, evaporation and other processes. For example, it can be an NTC / PTC thermistor, a semiconductor temperature sensing chip, etc.; and it can be prepared at a designated position by assembly, pasting, printing, deposition and other methods.

[0109] In one embodiment, the absorption portion 101 of the care product is further provided with a temperature sensing module for sensing at least the temperature value of a first position point where the user excretes feces, 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 FIG6 .

[0110] Step S150, obtaining the temperature value of the first location;

[0111] In step S160 , if the temperature value at the first location increases and the humidity value at the first location is less than a first humidity threshold, the metabolite type is determined to be a solid metabolite.

[0112] It is understood that the first humidity threshold may be less than or equal to the maximum humidity value of the absorbent portion 101 when solid metabolites are excreted into the absorbent portion 101. If the temperature value at the first location increases, it indicates that metabolites are present at the first location. If the humidity value at the first location is less than the first humidity threshold, it indicates that the metabolites are solid metabolites, where the solid metabolites may be, for example, dry feces.

[0113] In one embodiment, the absorption part 101 of the care product is further provided with a temperature sensing module for sensing the temperature value of a second position point set, wherein the second position point set includes a plurality of position points on the absorption part 101 corresponding to the user's excretion sites when the care product is worn. The method also includes steps S170 and S180, as shown in FIG7 .

[0114] Step S170 , obtaining temperature values ​​of the second set of location points, and determining temperature diffusion information according to the temperature values, wherein the temperature diffusion information is used to characterize the order in which the temperature rise changes occur at each location point.

[0115] It is understood that the temperature sensing module continuously collects the temperature values ​​of each location point. When metabolites are excreted at a location point, the temperature of the location point will increase. By obtaining the temperature value of each location point, and then determining the temperature increase order of each location point based on the change in each temperature value, that is, the order in which the metabolites fall into each location point. Among them, the temperature change of a location point can be when the temperature value of the location point exceeds the initial value. To improve detection accuracy, the temperature change of a location point can also be when the temperature value of the location point exceeds the temperature threshold.

[0116] Step S180: determining the metabolite type based on the temperature diffusion information.

[0117] It can be understood that different metabolites fall into different locations when excreted, and the locations they flow through during the diffusion process are also different. Therefore, the order in which the metabolites fall into various locations after excretion can be known based on the temperature diffusion information. Based on the one-to-one correspondence between each location point and each excretion site of the human body, different metabolites flow through different locations in a different order after excretion, and thus the type of metabolite can be determined.

[0118] The temperature diffusion information can be mapped to the metabolite type, and the corresponding metabolite type can be obtained based on the temperature diffusion information. Metabolite types can include liquid metabolites, such as urine and blood, and non-liquid metabolites, such as solid hard stool and paste-like loose stool.

[0119] In one embodiment, as shown in FIG1 , the second position point set includes a first position point A at a defecation site, a second position point B at a urination site of a female user, and a third position point C at a urination site of a male user, wherein the distance between the second position point B and the first position point A is less than the distance between the third position point C and the first position point A, and determining the metabolite type according to the temperature diffusion information includes step S181, as shown in FIG8 .

[0120] In step S181, if the temperature diffusion information indicates that the third position point C, the second position point B, and the first position point A successively undergo temperature increases, or if the second position point B, the first position point A, and the third position point C successively undergo temperature increases, then the metabolite type is determined to be a liquid metabolite.

[0121] It can be understood that the third position point C is the position point where male users urinate. If the user is a male, the urine will first flow through the third position point C when urinating, causing the temperature of the third position point C to rise, and then diffuse to both ends. When diffusing toward the defecation point, it will flow through the second position point B and the first position point A in turn, thereby causing the second position point B and the first position point A to change in temperature in turn. Therefore, when the third position point C, the second position point B, and the first position point A change in temperature one after another, it indicates that the male user has excreted liquid, and the metabolite may be urine.

[0122] The second location B is where female users urinate. If the user is female, metabolites will first flow through the second location B when urinating or during menstruation, causing the temperature of the second location B to rise and then diffuse to both ends. Because the distance between the first location A and the second location B is smaller than the distance between the third location and the second location B, the first location A will come into contact with the metabolites before the third location C, and the first location A will experience a temperature change before the third location C. Therefore, when the second location B, the first location A, and the third location C experience a temperature change in succession, it indicates that the female user has excreted liquid, and the metabolites may be urine or blood.

[0123] In one embodiment, the first position point set includes a first position point A at the defecation site, a second position point B at the urine site of a female user, and a third position point C at the urine site of a male user, wherein the distance between the second position point B and the first position point A is less than the distance between the third position point C and the first position point A, and determining the metabolite type based on the temperature diffusion information also includes step S182, as shown in FIG9 .

[0124] In step S182 , if the temperature diffusion information indicates that the first location point A, the second location point B, and the third location point C successively undergo temperature increases, then the metabolite type is determined to be a non-liquid metabolite.

[0125] It can be understood that the first location A is the location where the user defecates. Regardless of whether the user is male or female, when defecating, the metabolites will first flow through the first location A, causing the temperature of the first location A to rise, and then diffuse to both ends. When it diffuses toward the user's urination location, the second location B and the third location successively come into contact with the metabolites, and thus successively experience temperature changes. Therefore, when the first location A, the second location B, and the third location C successively experience temperature changes, it indicates that the user has performed non-liquid excretion behavior, and the metabolites may be feces.

[0126] The above embodiment is based on the flow of metabolites through the care product during the user's excretion process. Position points corresponding to the human body's excretion parts are set on the care product. The type of excrement is then determined based on the order in which the temperature changes occur when each position point contacts the excrement. The method is simple and the detection results are accurate.

[0127] In one embodiment, the diffusion rate of the metabolite may also be obtained according to the temperature value, so as to determine whether the metabolite is a solid metabolite or a semi-solid metabolite according to the diffusion rate.

[0128] In one embodiment, if the metabolite type is a liquid metabolite, the method further includes steps S210 and S220 , as shown in FIG12 .

[0129] Step S210 , obtaining humidity values ​​of the second location point set, and determining the metabolic amount of the liquid metabolite according to the humidity values.

[0130] Step S220: If the metabolic rate exceeds the warning value, a warning message is output.

[0131] It is understood that to prevent excessive accumulation of liquid metabolites in nursing products, which would affect the subsequent absorption of the nursing products and even affect the health of the user, the metabolic amount of liquid metabolites can be further detected. When the set warning value is exceeded, a warning message is output to remind the user to replace the liquid metabolites. The warning message can be an audio signal or a display message.

[0132] In one embodiment, determining the metabolic amount of liquid metabolites according to the humidity value includes step S211 and step S212.

[0133] Step S211 : determining a target number according to the humidity value, where the target number is the number of location points whose humidity values ​​are greater than a second humidity threshold.

[0134] Step S212: determining the metabolic amount according to the target amount.

[0135] It can be understood that if the humidity value of a position point is greater than the second humidity threshold, it means that there is liquid metabolite at the position point. By reasonably setting the spacing between each position point, the number of position points that come into contact with the liquid metabolite corresponds to the metabolic amount, so that the corresponding metabolic amount can be obtained according to the number of position points.

[0136] As shown in Figure 1, let's assume the first set of location points includes location points A, B, C, D, E, F, and G. For example, for a male user, penetration areas L1-L4 can be divided based on each location point, with penetration areas L1-L4 increasing in size. When only one location point contacts liquid excrement, the liquid excrement is located within area L1, and the corresponding metabolic rate for area L1 can be 20ml. When three location points contact liquid excrement, the liquid excrement is located within area L2, and the corresponding metabolic rate for area L2 can be 40ml. Similarly, the metabolic rate for area L2 can be 40ml, and the metabolic rate for area L4 can be 120ml. The corresponding metabolic rate can be determined based on the target number. This method is simple and can effectively measure metabolic rates.

[0137] In one embodiment, the first position point set includes at least a target position point, and the target position point includes at least one of a second position point B and a third position point C, the second position point is the position point where the female user urinates, and the third position point is the position point where the male user urinates. Determining the metabolic amount of the liquid metabolite based on the humidity value includes steps S213 and S214.

[0138] Step S213, obtaining the time interval between the growth moment and the decay moment of the humidity value of the target location point, the growth moment is the moment when the growth rate of the humidity value of the target location point reaches the growth threshold, and the decay moment is the moment when the decay rate of the humidity value of the target location point reaches the decay threshold.

[0139] Step S214 , obtaining the metabolic amount according to the time interval and the preset excretion flow rate, where the preset excretion flow rate is the excretion volume of the liquid metabolite per unit time.

[0140] It can be understood that in order to determine the metabolic rate, the excretion time of liquid metabolites during the user's excretion process can also be obtained, and the metabolic rate can be further determined by combining the excretion volume per unit time. The excretion time is the time interval between the time the user starts excreting and the time the user ends excreting. The start time of excretion can be represented by the growth time of the humidity value at the user's urination excretion location. Since liquid excrement will be quickly absorbed after discharge, if the excretion stops, the humidity value of the location will decrease. Therefore, the end time of excretion can be represented by the decay time of the humidity value at the user's urination excretion location. Among them, the humidity value of the location point at the growth moment increases sharply, so it can be determined based on whether the growth rate of the humidity value at the target location point reaches the growth threshold. The humidity value of the location point at the decay moment will decay sharply, so it can be determined based on whether the decay rate reaches the decay threshold. Among them, the collected humidity value can be timestamp, so that the growth moment and decay moment can be determined based on it.

[0141] In one embodiment, the absorption part 101 is further provided with a component detection module for detecting metabolite component information of at least one position point on the metabolite diffusion path of the absorption part 101. The method also includes obtaining the metabolite component information and determining the metabolite type according to the metabolite component information.

[0142] It is understandable that different metabolites contain different urea contents, and therefore it is possible to determine whether the metabolite is a liquid metabolite or a non-liquid metabolite based on the urea content in the metabolite.

[0143] The component detection module may be arranged at a position corresponding to the user's excretion site, or may be arranged at other positions that may be exposed to metabolites during the user's excretion process.

[0144] In one embodiment, to improve the accuracy of the determination, the temperature change occurring at each location point may be that the temperature value of each location point exceeds a temperature threshold.

[0145] FIG13 is a schematic flow chart of a metabolite detection method according to another embodiment, the specific steps of which have been described in detail in the above embodiments and will not be repeated here.

[0146] An embodiment of the present invention also provides a nursing product, including a humidity sensing module and a detection module. The humidity sensing module is arranged in the absorption part 101 of the nursing product, and is used to sense the humidity value of a first position point set, wherein the first position point set includes multiple position points located on the metabolite diffusion path of the absorption part 101; the detection module is used to obtain the humidity value of the first position point set, and determine the growth status information of the position point based on the humidity value, the growth status information is used to characterize the growth of the humidity of the position point over time; and determine the metabolite type based on the growth status information, wherein the metabolite type includes liquid metabolites and non-liquid metabolites.

[0147] The principles and beneficial effects of the nursing product of this embodiment are similar to those of the above-mentioned metabolite detection method embodiment, and are not described in detail here.

[0148] In one embodiment, the first position point set includes at least two position point subsets, wherein the distances between the position points in different position point subsets and the position points at which the user urinates fall within different distance ranges, and the humidity sensing module includes: multiple humidity sensitive units, the humidity sensitive devices form at least two humidity sensitive modules, the humidity sensitive units in the same humidity sensitive module are connected in parallel, and the humidity sensitive modules are respectively connected to the detection modules, and are respectively used to detect the humidity values ​​of the position point subsets in a one-to-one correspondence.

[0149] As shown in Figure 14 , assuming that the second subset of location points B may include location points A, B, C, D, E, F, and G, when determining the target quantity based on the humidity value, and thus the metabolic amount of the liquid metabolite, at least two detection networks may be formed to reduce the overall structural complexity. Taking two detection networks as an example, location points DCE are closer to the excretion site and experience significant humidity changes, so one detection network may be used. Location points ABFG are farther from the excretion site and experience less significant humidity changes, so another detection network may be used. The humidity-sensitive units 103 within the same detection network are connected in parallel, thereby reducing the complexity of the design structure. The humidity sensitive unit 103 may include one or more humidity sensitive devices. When it includes multiple humidity sensitive devices, the humidity sensitive devices in the same humidity sensitive unit 103 may be connected in series, in parallel, or in a combination of series and parallel. The humidity sensitive unit 103 may be a capacitive humidity sensitive unit 103 or a resistive humidity sensitive unit 103. When it is a capacitive humidity sensitive unit 103, a parallel connection method is adopted. When it is a resistive humidity sensitive unit 103, a series connection method is adopted.

[0150] In one embodiment, the thermal sensor and the humidity sensor unit 103 located at the same point can be integrated into a sensor unit to reduce the overall volume.

[0151] In one embodiment, the humidity sensing module may include multiple first humidity sensitive units 103, and the multiple first humidity sensitive units 103 are respectively arranged at each position point in the first position point set, wherein the sensitivity of each first humidity sensitive unit 103 is inversely proportional to the distance between the first humidity sensitive unit 103 and the position point where the user urinates.

[0152] It is understood that, as shown in FIG14 , the humidity sensing module may include only one row of first humidity-sensitive units 103, which may be located in the middle of the absorption portion 101 to detect the humidity value of each location point. When determining the target quantity based on the humidity value, and then determining the metabolic amount of the liquid metabolite, in order to reduce costs and reduce the complexity of the overall structure, a first humidity-sensitive unit 103 with higher sensitivity may be used at a point near the urine excretion location, while a first humidity-sensitive unit 103 with lower sensitivity may be used at a point far from the urine excretion location. The first humidity-sensitive unit 103 may include one or more humidity-sensitive devices. When multiple humidity-sensitive devices are included, the humidity-sensitive devices within the same humidity-sensitive unit 103 may be connected in series, in parallel, or in a combination of series and parallel. The sensitivity of the first humidity-sensitive unit 103 may be adjusted by changing the number of humidity-sensitive devices.

[0153] In one embodiment, the humidity sensing module also includes multiple groups of second humidity sensitive units 103, which are connected one-to-one to each first humidity sensitive unit 103, wherein the straight line where the same group of second humidity sensitive units 103 and the corresponding first humidity sensitive units 103 are located is perpendicular to the straight line where each first humidity sensitive unit 103 is located.

[0154] It is understandable that, considering the scenario where the care product may be worn sideways, multiple groups of second moisture-sensitive units 103 may be provided to form a moisture-sensitive unit 103 array, so that any moisture-sensitive unit that detects metabolites can accurately distinguish whether there is excretion behavior.

[0155] In one embodiment, the care product further includes a temperature sensing module, which is arranged in the absorption part 101 and is used to sense the temperature value of a second position point set, wherein the second position point set includes multiple position points on the absorption part 101 corresponding to the user's excretion sites when the care product is worn; the detection module is also used to obtain the temperature value of the second position point set, and determine the temperature diffusion information based on the temperature value, and the temperature diffusion information is used to characterize the order in which the temperature changes occur at each position point; the metabolite type is determined based on the temperature diffusion information; wherein the temperature sensing module includes multiple temperature sensing units 102, and each temperature sensing unit 102 is respectively arranged in a one-to-one correspondence with each position point in the first position point set.

[0156] As shown in Figure 14, a temperature sensing unit 102 is provided at each of the first location point A, the second location point B, and the third location point C in the first location point set to detect the temperature value of each location point.

[0157] In one embodiment, the temperature sensing unit 102 may include a plurality of thermosensitive devices, and the thermosensitive devices are connected in series or in parallel.

[0158] It is understood that to improve the detection accuracy of the temperature sensing unit 102, multiple thermal sensors can be provided to form the temperature sensing unit 102, thereby increasing the detection range and providing a certain degree of tolerance for the location of the metabolite. Thermistors made of negative temperature coefficient materials (NTCs) can be connected in parallel, while thermistors made of positive temperature coefficient materials (PTCs) can be connected in series to improve detection sensitivity.

[0159] In one embodiment, the absorption part 101 includes a first base layer and a first wicking layer, and the sensing part of the humidity sensing module is arranged on the side of the first base layer close to the human body; the first wicking layer covers the sensing part of the humidity sensing module and is used to absorb and lock the liquid in the metabolite.

[0160] It can be understood that since the water-absorbing resin particles in the core of the absorption part 101 of the care product have a very strong water-absorbing effect, in order to ensure that sufficient moisture can reach the surface of the moisture-sensitive unit 103, a first wicking layer can be prepared on the electrode surface of the moisture-sensitive unit 103 to lock in moisture and ensure the accuracy of detection, wherein the first wicking layer may include a water-absorbing material (such as water-absorbing resin, polyurethane, foam glue, etc.).

[0161] In one embodiment, the care product further includes a component detection module, which is arranged in the absorption part 101 and is used to detect the metabolite component information of at least one position point on the metabolite diffusion path of the absorption part 101; the detection module is also used to obtain the metabolite component information and determine the metabolite type based on the metabolite component information; the component detection module includes a liquid phase detector and / or a gas phase detector.

[0162] When a liquid phase detector is included, as shown in FIG15 , the absorption portion 101 further includes a second base layer 104 and a second siphon layer 107. The sensing portion 106 of the liquid phase detector is disposed on the side of the second base layer 104 that is closest to the human body. The second siphon layer 107 covers the sensing portion 106 of the liquid phase detector and is used to absorb and lock the liquid in the metabolites. Reference numeral 105 is a connecting circuit for the liquid phase detector. The liquid phase substances to be detected include, but are not limited to, at least one of pH value, glucose, dopamine, uric acid, ascorbic acid, galactose, ketone bodies, white blood cells, protein, occult blood, K+ ions, Na+ ions, iodide ions, calcium ions, iron ions, zinc ions, and nitrite.

[0163] It can be understood that liquid phase component analysis requires the establishment of a stable reaction zone, thereby forming a part of the siphon channel to ensure that the urine in the reaction zone is sufficient within the detection time. Otherwise, the urine may be absorbed by the core layer of the diaper and cannot meet the needs of biochemical detection. The above-mentioned second siphon layer 107 provides a stable reaction zone. Urine enters the reaction zone through siphon action and is detected by the detection device in the reaction zone. Among them, the second siphon layer 107 can include an interlayer and a hydrophilic layer from bottom to top. Furthermore, the entrance of the siphon channel for liquid phase component analysis can also be achieved by punching holes in the base layer; the entire reaction zone can also be realized with a polymer porous water-absorbing material.

[0164] When the component detection module includes a gas phase detector, as shown in Figure 16, the absorption part 101 also includes a third base layer 108 and a latching layer 111. The sensing part 110 of the gas phase detector is arranged on the side of the base layer close to the human body; the latching layer 111 covers the sensing part 110 of the gas phase detector and is used to latch the gas in the metabolite. Among them, 109 is a connecting line of the gas phase detector to transmit the sensing signal to the back end. Among them, the gas phase substances to be detected include but are not limited to at least one of ammonia, hydrogen sulfide, hydrogen, skatole, etc. In addition, a protective film layer can also be covered on the latching layer 111 to prevent the latching layer 111 from being physically scratched and damaged by external substances. The above-mentioned base layer is a carrier of the sensing part and the connecting line.

[0165] The care products in the above embodiments may be diapers, nursing pads, sanitary napkins and other care products.
