[0029] Figure 1 is a schematic system structural diagram of one embodiment of a metabolite detection device, in which the metabolite detection device of this embodiment is applied to a diaper. Referring to Figure 1, in this embodiment, the metabolite detection device includes a sensing module 100 and a processing module 200.

[0030] The sensing module 100 includes a sensing unit 110, a signal conditioning chip 120, and a first coil 130, which are connected in sequence. The sensing unit 110 detects metabolites and generates a plurality of corresponding sensing signals. The signal conditioning chip 120 may include multiple sensors disposed along the diffusion path of metabolites, each generating a corresponding sensing signal. The signal conditioning chip 120 processes each sensing signal to generate a corresponding conditioning signal and transmits the conditioning signals to the first coil 130 for transmission. Specifically, the signal conditioning chip 120 may have a signal modulation function, such as amplifying a relatively weak signal output from the sensing unit 110, adjusting the voltage of a signal whose voltage range does not meet the voltage input requirements of a subsequent module, and filtering noise other than the signal to output a relatively clean conditioning signal. The signal conditioning chip 120 may further have at least one of functions such as digital-to-analog conversion, non-volatile memory, simple logic operation, and wireless modulation.

[0031] The processing module 200 includes a second coil 210 and a data processing unit 220 connected to each other. The second coil 210 is electromagnetically coupled to the first coil 130 to wirelessly transmit energy and data. The second coil 210 receives the plurality of regulating signals and transmits the plurality of regulating signals to the data processing unit 220. It should be understood that, during use, the signal conditioning chip 120 may transmit data to the processing module 200 once at regular time intervals, or the signal conditioning chip 120 may return data in response to an acquisition command from the processing module 200, and this embodiment is not limited thereto. The data processing unit 220 acquires metabolite information based on the plurality of regulating signals. Specifically, the metabolite information may include, but is not limited to, the type of metabolite. After receiving the regulating signals, the processing module 200 may determine the detection results of the detection points based on the regulating signals, and further determine the type of metabolite based on the detection results.

[0032] In this embodiment, compared to the related art, where the sensing unit 110 is directly connected to the processing module 200 by wiring, the wired connection between the sensing unit 110 and the processing module 200 is converted to a wireless connection by installing a signal conditioning chip 120 between them and controlling the first coil 130 to transmit and receive signals using a signal conditioning signal, thereby reducing the length of the wiring and simplifying the wiring. Furthermore, since the wiring connection between the processing module 200 and the signal conditioning chip 120 is omitted, the processing module 200 does not need to install a connector for the wiring connection. This eliminates the need for a rigid reinforcement plate, omitting the reinforcement process and facilitating roll processing, saving material and process costs and improving processing efficiency. At the same time, this greatly improves user convenience during assembly and facilitates functional expansion of the sensing module. Furthermore, since the first coil and the second coil can transmit energy via wireless coupling, the energy wirelessly received by the first coil in the sensing module can supply power to devices such as the sensing unit and the signal conditioning chip. According to the above power supply method, there is no need to install a structure such as a battery in the sensing module, which simplifies the structure of the sensing module and further simplifies the overall structure of the diaper.

[0033] In one embodiment, when the sensing unit 110 includes multiple sensors, the signal conditioning chip 120 is provided with multiple sensing channel interfaces, each connected to a corresponding one of the sensors. As can be appreciated, the sensing channel interfaces can be designed as needed, making it easier to accommodate an increasing number of sensors. Furthermore, because the signal conditioning chip 120 is small in volume, adding a sensing channel interface does not significantly affect the overall device footprint. As can be appreciated, when the number of sensors increases and more data is detected, compatibility can be achieved simply by changing the connection relationship between the sensors and the sensing channel interfaces, which is simple and easy to implement and more advantageous for expanding the functionality of the metabolite detection device.

[0034] In one embodiment, the signal conditioning chip 120 is configured with an updatable signal conditioning algorithm, and the signal conditioning algorithm is configured to correspond to the types of sensors in the sensing unit 110. That is, more extensive signal conditioning functions can be achieved by simply updating the signal conditioning algorithm in the signal conditioning chip 120. Therefore, product upgrades can be completed with a simple software algorithm update, without the need to update the hardware structure of the signal conditioning chip 120.

[0035] In one embodiment, the signal conditioning chip 120 is further configured with preset identification information. Accordingly, the signal conditioning chip 120 has a memory function for recording the identification information of each diaper. The identification information includes, but is not limited to, information such as diaper ID information. When the signal conditioning chip 120 transmits the plurality of conditioning signals to the first coil 130, the signal conditioning chip 120 also transmits the identification information to the first coil 130 for the processing unit to establish a mapping relationship between the metabolite information and the identification information. In this embodiment, the processing module 200 can determine the correspondence between the metabolite information and the signal conditioning chip 120. Furthermore, once the correspondence between the identification information of the signal conditioning chip 120 and the user usage information is established, the user's name, diaper wearing time, etc. corresponding to each metabolite information can also be known, thereby facilitating tracking and data analysis.

[0036] In one embodiment, the data processing unit 220 further generates a data acquisition command and transmits it via the second coil 210. The signal conditioning chip 120 further receives the data acquisition command via the first coil 130 and transmits the adjustment signal back to the data processing unit 220 in response to the data acquisition command. As can be understood, to determine whether the user needs to change the diaper, the user needs to open the APP of the mobile terminal and inquire about the current usage status of the diaper. Therefore, by installing the above function, real-time data can be obtained, thereby providing the user with accurate information and improving the user's usage experience.

[0037] FIG. 2 is a schematic diagram (part 1) of a sensor according to one embodiment. Referring to FIG. 2, in one embodiment, the sensing unit 110 includes multiple humidity sensors, each mounted on a substrate of the sensing layer 14. The substrate is made of a flexible material that conforms to the user's body and has conductive wires embedded therein for transmitting sensing signals from each sensor. The multiple humidity sensors are respectively disposed at different measurement points on the metabolite diffusion path, and each humidity sensor measures the humidity at the measurement point and generates a corresponding humidity sensing signal. The number of humidity sensors may be 5 to 10, and may be determined based on the size of the diaper. The data processing unit 220 further determines the type of metabolite, including liquid metabolites and non-liquid metabolites, based on the humidity sensed by each humidity sensor. Specifically, the processing module 200 can obtain incremental status information based on the measurement results of each sensor and determine the type of metabolite based on the incremental status information. The increase status information characterizes the increase in the measurement results of each measurement point over time, and may include, for example, the rate of humidity increase, the time for which the humidity is maintained within a predetermined humidity range after the humidity has increased, and the status of maintaining the humidity within a predetermined temperature range after the humidity has increased.

[0038] As an example, the processing module 200 further determines that the type of metabolite is a liquid metabolite if the humidity increase rate of at least one measurement point is greater than a speed threshold. The speed threshold may be determined based on an empirical value of the humidity increase rate when the liquid metabolite diffuses in the core layer of the diaper. In another example, the processing module 200 further determines that the type of metabolite is a semi-solid metabolite if the retention time of at least one measurement point is greater than a first time threshold, and / or determines that the type of metabolite is a liquid metabolite if the retention time of any measurement point is less than a second time threshold. The semi-solid metabolites refer to stool containing liquid in the metabolites, and may be, for example, loose stool. As can be understood, the first time threshold may be determined based on the user's normal continuous urination time, for example, equal to or greater than the user's longest urination time. Because liquid metabolites are quickly absorbed into the core layer of the diaper after being excreted, their moisture may be maintained only in the case of continuous urination. When semi-solid metabolites contain liquid, such as liquid in the metabolites, and the liquid in the metabolites is not quickly and completely absorbed into the core layer of the diaper, the moisture at the measurement points is maintained for a certain period of time. If the maintenance time of at least one measurement point exceeds the first time threshold, i.e., exceeds the user's normal urination time, the maintenance of moisture at the measurement point is not due to urination but due to semi-solid metabolites, and therefore, the type of metabolite can be determined to be semi-solid metabolites. FIG. 3 shows a graph of humidity change of semi-solid metabolites in one embodiment. Referring to FIG. 3, graph l1 is a graph of change over time, and graph l2 is a graph of change in humidity value of semi-solid metabolites. Liquid metabolites may be, for example, liquids, blood, etc. in the metabolites. The second time threshold may be determined based on the user's usual continuous urination time, for example, equal to or shorter than the longest urination time. It can be understood that if the maintenance time of at least one measurement point is shorter than the first time threshold, i.e., shorter than the user's normal urination time, it indicates that the maintenance of humidity at that measurement point is due to a urination situation, and therefore, the type of metabolite can be determined to be a liquid metabolite. FIG. 4 shows a graph of humidity change of liquid metabolites in one embodiment. Referring to FIG. 4, graph l3 is a graph of change over time, and graph l4 is a graph of change in humidity value of liquid metabolites. The first time threshold and the second time threshold may be equal.

[0039] FIG. 5 is a schematic diagram of a sensor according to an embodiment (part 2). Referring to FIG. 5, in one embodiment, the sensing unit 110 includes at least one temperature sensor disposed on the metabolite diffusion path, which detects the temperature at the detection point and generates a corresponding temperature sensing signal. In the embodiment shown in FIG. 5, the sensing unit 110 includes three temperature sensors. The data processing unit 220 further determines the types of metabolites, including liquid metabolites and non-liquid metabolites, based on the temperatures sensed by the temperature sensors.

[0040] Specifically, the increase status information may further include a time period during which the humidity is maintained within a predetermined temperature range after the humidity increase. The processing module 200 further determines that the type of metabolite is a semi-solid metabolite if the increase status information of at least one humidity measurement point satisfies the predetermined condition while the temperature of an adjacent temperature measurement point gradually decreases. As can be understood, if the metabolite is a semi-solid metabolite, the liquid in the metabolite is not quickly and completely absorbed by the core layer of the diaper, so that the humidity remains within a certain range even after excretion, and the temperature gradually decreases after excretion, rather than continuously increasing or remaining within a certain temperature range as in continuous urination. Therefore, for a certain measurement point, if the humidity at that measurement point remains within a predetermined humidity range after the humidity increase, while the temperature at that measurement point gradually decreases, the type of metabolite can be determined to be a semi-solid metabolite.

[0041] In one embodiment, the data processing unit 220 further determines a target number, which is the number of measurement points whose humidity is greater than a second humidity threshold, based on the humidity, and determines a metabolic rate based on the target number. The second humidity threshold may be the humidity of the core layer of the diaper when liquid metabolites are excreted into the core layer of the diaper. As can be understood, if the humidity of a measurement point is greater than the second humidity threshold, it indicates that the measurement point contains liquid metabolites. By rationally setting the distance between each measurement point, the number of measurement points that come into contact with liquid metabolites corresponds one-to-one to the metabolic rate, thereby obtaining the corresponding metabolic rate based on the number of measurement points.

[0042] FIG. 6 is a schematic diagram showing the positions of the humidity sensors in one embodiment. Referring to FIG. 6, the humidity sensors are installed at humidity detection points A, B, C, D, E, F, and G in one-to-one correspondence. Based on the measurement points, permeation regions L1 to L4 can be defined, with the area of ​​the permeation regions L1 to L4 increasing sequentially. When only one measurement point contacts the liquid excrement, the liquid excrement is located within region L1, and the metabolic rate corresponding to region L1 may be 20 ml. When three measurement points contact the liquid excrement, the liquid excrement is located within region L2, and the metabolic rate corresponding to region L2 may be 40 ml. Similarly, the metabolic rate corresponding to region L2 may be 40 ml, and the metabolic rate corresponding to region L4 may be 120 ml. Therefore, in this embodiment, the corresponding metabolic rate can be determined based on the target number, and the method is simple and can effectively measure the metabolic rate.

[0043] In some embodiments, to determine the metabolic rate, the excretion time of the liquid metabolites during the user's excretion is acquired, thereby further determining the metabolic rate in conjunction with 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 stops excreting. The time the excretion starts can be characterized by the time the humidity at the user's urination measurement point increases. Because liquid excretion is quickly absorbed after being excreted, the humidity at the measurement point decreases when excretion stops. Therefore, the time the excretion ends can be characterized by the time the humidity at the user's urination measurement point decreases. The increase time indicates a rapid increase in humidity at the measurement point, and can be determined based on whether the increase rate of the humidity at the target measurement point reaches an increase threshold. The decrease time indicates a rapid decrease in humidity at the measurement point, and can be determined based on whether the decrease rate reaches a decrease threshold. The collected humidity may have a timestamp, based on which the increase time and decrease time can be determined.

[0044] In one embodiment, the temperature sensor further senses the temperature at at least the temperature detection point at the user's defecation position and transmits the sensed temperature to the processing module 200 via the signal conditioning chip 120. At least one sensor is installed at the temperature detection point and senses the humidity at the temperature detection point. The processing module 200 further determines that the type of metabolite is solid metabolite when the temperature at the temperature detection point increases and the humidity at the adjacent humidity detection point is lower than a first humidity threshold. As can be understood, the first humidity threshold may be equal to or lower than the maximum humidity of the core layer of the diaper when the solid metabolite is excreted into the core layer of the diaper. When the temperature at the first detection point increases, it indicates the presence of metabolites at the first detection point. At the same time, when the humidity at the first detection point is lower than the first humidity threshold, it indicates the presence of solid metabolites, which may be, for example, dry feces.

[0045] In one embodiment, the temperature sensor further detects the temperature of multiple detection points on the core layer of the diaper corresponding to each excretion site of the user while the diaper is worn. The data processing unit 220 further determines temperature diffusion information based on the temperature and determines the type of metabolite based on the temperature diffusion information. The temperature diffusion information represents the order in which the temperature changes at each detection point. Specifically, if the temperature diffusion information indicates a sequential temperature change from the detection point at the urination site to the detection point at the defecation site, the type of metabolite is determined to be liquid metabolite. If the temperature diffusion information indicates a sequential temperature change from the detection point at the defecation site to the detection point at the urination site, the type of metabolite is determined to be non-liquid metabolite. As can be understood, the specific type of metabolite can be determined based on the excretion site and diffusion status of the metabolite. Liquid metabolites may include liquid or blood in the metabolite, and non-liquid metabolites may include solid metabolites, such as dry stool, or semi-solid metabolites, such as soft stool.

[0046] FIG. 7 is a schematic diagram of a sensor according to an embodiment (part 3). Referring to FIG. 7, in one embodiment, the sensing unit 110 further includes a liquid-phase metabolite sensor. The liquid-phase metabolite sensor is disposed in the biochemical reaction area of ​​the diaper, detects the liquid flowing into the biochemical reaction area from the liquid siphon passage of the diaper, and generates a corresponding liquid-phase biochemical sensing signal. The data processing unit 220 further acquires liquid-phase biochemical information corresponding to the liquid-phase biochemical sensing signal.

[0047] Specifically, the liquid-phase metabolic sensor is designed with separate liquid siphon passages and biochemical reaction regions to ensure detection of multiple metabolites without interference from droplet flow paths and mutual signals. Detectable substances include, but are not limited to, pH, glucose, dopamine, uric acid, ascorbic acid, galactose, ketone bodies, white blood cells, proteins, blood congestion, K+ ions, Na+ ions, iodine ions, calcium ions, iron ions, zinc ions, and nitrite. Specifically, FIG. 8 is a schematic cross-sectional view of one embodiment of a liquid-phase metabolic sensor. Referring to FIG. 8, the liquid-phase sensor's sensitive material layers are provided at each detection point on the substrate, and specific reactions of metabolites generate electrical signals. Separators are provided between adjacent sensitive material layers to separate the adjacent sensitive material layers and form siphon passages to confine the liquid in the metabolites. A hydrophilic membrane layer is provided on top of the separator to absorb the liquid in the metabolites and guide the liquid into the siphon passage. In the embodiment shown in Figure 8, the siphon channel entrance for liquid-phase component analysis is achieved by perforating the hydrophilic membrane layer. It is understood that liquid-phase component analysis requires the establishment of a stable reaction area to ensure that there is sufficient liquid in the metabolites in the reaction area within the detection time; otherwise, the liquid in the metabolites may be absorbed into the core layer of the diaper, which may not meet the requirements for biochemical detection. The above structure provides a stable reaction area, allowing the liquid in the metabolites to enter the reaction area by siphoning and be detected by the sensitive layer of the reaction area, thereby achieving liquid-phase analysis.

[0048] Continuing to refer to FIG. 7, in one embodiment, the sensing unit 110 includes a gas-phase metabolite sensor and a gas-confining structure covering the gas-phase metabolite sensor. The gas-confining structure confines the metabolite gases, and the gas-phase metabolite sensor detects the trapped gases and generates corresponding gas-phase biochemical sensing signals. The data processing unit 220 further acquires gas-phase biochemical information corresponding to the gas-phase biochemical sensing signals. Similar to a siphon passage, the gas-confining structure can establish a stable reaction region, thereby ensuring that the gases in the reaction region are relatively stable within the detection time; otherwise, the metabolite gases will volatilize and fail to meet the biochemical detection needs. This structure provides a stable reaction region, and the metabolite gases are fixed in the reaction region by the gas-confining structure and detected by the sensitive layer in the reaction region, thereby achieving gas-phase analysis. Gas-phase analytes include, but are not limited to, ammonia, hydrogen sulfide, hydrogen, skatole, etc.

[0049] FIG. 9 is a schematic structural diagram of a processing module 200 in one embodiment. Referring to FIG. 9, in one embodiment, the processing module 200 further includes at least one of an operation unit 230, an instruction unit 240, and a power management unit 250.

[0050] Specifically, the operation unit 230 is connected to the data processing unit 220, receives an activation operation input by a user, generates a corresponding activation signal, and transmits the activation signal to the data processing unit 220. When the processing module 200 is placed in a storage bag, the processing module 200 automatically detects the sensing module 100 and transmits the activation signal to the sensing module 100 to establish communication with the sensing module 100, thereby obtaining information about the sensing module 100, such as its ID information, production time, placement information, and whether it has been used. The instruction unit 240 is connected to the data processing unit 220, receives the instruction signal output by the data processing unit 220, and instructs the user based on the status information included in the instruction signal, where the status information included in the instruction signal includes at least one of the metabolite status information, sensing module 100 status information, and processing unit status information. The metabolite status information refers to the number of excretion times, the length of use time, whether the detection index exceeds a set value, etc., the sensing module 100 status information refers to the switch status of the sensor, the electromagnetic coupling status of the coil, etc., and the processing unit status information refers to whether the processing module 200 is operating normally, whether the amount of power of the processing module 200 is normal, etc. As can be understood, the diaper liquid In order to prevent excessive accumulation of metabolites from affecting the subsequent absorption of the diaper and further affecting the health of the user, the instruction unit 240 can output warning information to prompt the user to change the diaper when the metabolic amount of liquid metabolites exceeds a set warning value. The warning information may be an audio signal. The power management unit 250 is connected to the data processing unit 220 and supplies power to the data processing unit 220.

[0051] An embodiment of the present application further provides a diaper. FIG. 10 is a schematic cross-sectional view (part 1) of a diaper according to one embodiment. Referring to FIG. 10, the diaper includes a top layer 11, a bottom layer 12, at least one core layer 13, and a sensing layer 14, with one core layer 13 shown in the figure. The top layer 11 is close to the user's skin, and the bottom layer 12 is far from the user's skin. The core layer 13 is disposed between the top layer 11 and the bottom layer 12. As in the metabolite detection device described above, the core layer 13 is also called an absorption layer and absorbs metabolites. The sensing layer 14 is disposed between the top layer 11 and the bottom layer 12, and at least one core layer 13 is disposed between the sensing layer 14 and the bottom layer 12. For example, if the diaper includes three core layers 13 stacked in sequence, the sensing layer 14 may be disposed between the first core layer 13 and the top layer 11, between the first core layer 13 and the second core layer 13, between the second core layer 13 and the third core layer 13, or between the third core layer 13 and the bottom layer 12, and the present embodiment is not limited thereto. The sensing module 100 of the metabolite detection device is disposed on the sensing layer 14, i.e., the sensing unit 110, the signal conditioning chip 120, and the first coil 130 of the metabolite detection device are all disposed on the sensing layer 14. Furthermore, the processing module 200 of the metabolite detection device is disposed on the outside of the bottom layer 12, i.e., the second coil 210 and the data processing unit 220 of the metabolite detection device are all disposed on the outside of the bottom layer 12. In this embodiment, the treatment module 200 is placed away from the user's skin and may be used to replace the treatment module 200 at any time, or to allow metabolites to flow into the treatment module 200 and affect its operation.

[0052] 10 , in one embodiment, a portion of the core layer 13 is disposed in a coupling path between the first coil 130 and the second coil 210 in the metabolite treatment device. The processing unit further acquires an electromagnetic coupling efficiency along the coupling path and acquires the amount of metabolites absorbed in the core layer 13 based on the electromagnetic coupling efficiency. As can be seen, the moisture absorption state of the core layer 13 affects the electromagnetic coupling efficiency, and therefore can be used to determine the amount of metabolites and whether or not a diaper change is required according to a designed algorithm.

[0053] FIG. 11 is a cross-sectional schematic diagram (part 2) of a diaper according to one embodiment. Referring to FIG. 11, in one embodiment, the core layer 13 is not installed in the coupling path between the first coil 130 and the second coil 210 in the metabolite treatment device. As can be seen, when the core layer 13 is not installed in the coupling path, the influence of the moisture absorption state of the core layer 13 on the electromagnetic coupling efficiency can be avoided, thereby effectively preventing the connection between the first coil 130 and the second coil 210 from becoming unstable or being disconnected when the diaper is not changed for a long period of time. Therefore, in this embodiment, the installation of the above structure can effectively ensure the reliability of communication.

[0054] In one embodiment, the diaper further includes a storage bag. The storage bag is connected to the outside of the bottom layer 12 and stores the treatment module 200. The storage bag has an opening and a switch structure at the opening. When the switch structure is lifted, the opening is exposed and the treatment module 200 is inserted or removed through the opening. When the switch structure is closed, the opening is closed to prevent the treatment module 200 from slipping out during operation. Specifically, when a user changes a diaper, the treatment module 200 is attached to the storage bag of a new diaper, thereby reducing the user's usage costs. Furthermore, a wired connection is provided. Compared to the conventional wireless connection method, the diaper of the present embodiment does not require operations such as aligning the connecting line when attaching or detaching the processing module 200, thereby improving the convenience of attachment and detachment. Furthermore, upgrading the software functions of the processing module 200 allows the diaper to support more comprehensive detection and analysis functions. As can be seen, the wireless connection method eliminates the need to modify the hardware structure of the processing module 200, such as the pins and connecting lines, after upgrading the software functions, thereby effectively improving the functional expandability of the processing module 200 without excessively increasing costs. In this embodiment, the provision of a storage bag prevents the processing module 200 from moving excessively, thereby ensuring the reliability of the communication process. Furthermore, the provision of an opening with a switch mechanism in the storage bag prevents the processing module 200 from accidentally slipping out of the storage bag, thereby further improving reliability.

[0055] In one embodiment, the receiving bag is installed at a position corresponding to the first coil 130 in the sensing module 100 to minimize the coupling path between the second coil 210 and the first coil 130. This installation method maximizes the transmission efficiency between the two coils, thereby improving the communication speed.

[0056] An embodiment of the present application further provides a care system. FIG. 12 is a schematic structural diagram of the care system according to one embodiment. Referring to FIG. 12, the care system includes a mobile terminal and the above-described diaper. The mobile terminal includes a first wireless transmission unit, and the processing module 200 of the diaper further includes a second wireless transmission unit 260 (see FIG. 9 ). The second wireless transmission unit 260 is connected to a data processing unit 220, transmits the metabolite information to the first wireless transmission unit of the mobile terminal, and receives control commands from the first wireless transmission unit. The processing module 200 in the diaper serves as a host, and transmits monitoring data to the APP of the mobile terminal via the wireless transmission unit. The APP of the mobile terminal receives the data transmitted from the processing module 200, processes the data, and displays it on the UI screen of the APP, enabling functions such as user browsing and feedback.

[0057] 12 , in one embodiment, the care system further includes a cloud server, and the mobile terminal further transmits the metabolite information to the cloud server, which stores and analyzes the received metabolite information. The APP of the mobile terminal can also transfer the acquired data to the cloud, thereby realizing cloud storage of data and richer analysis and application decision functions, thereby improving the flexibility of the usage process.
