Background Art

[0002] Diapers such as diapers, paper diapers, sanitary napkins, and care pads are widely used for infants, women, and people with urinary and fecal incontinence.

[0029] FIG. 1 is a schematic structural diagram of a metabolite detection device according to an embodiment. The metabolite detection device of this embodiment is applied to a diaper. Referring to FIG. 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 that are sequentially connected. The sensing unit 110 detects metabolites and generates a plurality of corresponding sensing signals. The sensing unit 110 It may include a plurality of sensors provided on the diffusion path of the metabolite, and each of the sensors generates one corresponding sensing signal. The signal conditioning chip 120 processes each of the sensing signals to generate a corresponding conditioning signal, and transmits the plurality of conditioning signals to the first coil 130 for transmission. Specifically, the signal conditioning chip 120 may have a signal modulation function. For example, it can amplify and enhance a relatively weak signal output by the sensing unit 110, perform voltage adjustment on a signal whose voltage range does not match the voltage input requirement of the subsequent module, and can also output a relatively clean conditioning signal by filtering noise other than the signal. The signal conditioning chip 120 may further have at least one of functions such as digital - analog conversion, non - volatile memory, simple logical operations, 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 to the first coil 130. The second coil 210 receives the plurality of conditioning signals and transmits the plurality of conditioning signals to the data processing unit 220. As can be understood, during use, the signal conditioning chip 120 may send 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 of the processing module 200, which is not limited in this embodiment. The data processing unit 220 obtains metabolite information based on the plurality of conditioning signals. Specifically, the metabolite information may include, but is not limited to, the type of metabolite. After receiving the conditioning signal, the processing module 200 may determine the detection result of the detection point based on the conditioning signal, and further determine the type of metabolite based on the detection result.

[0032] In this embodiment, compared with the case of directly connecting the sensing unit 110 to the processing module 200 by wiring as in the related art, a signal conditioning chip 120 is installed therebetween, and the first coil 130 is controlled to transmit and receive signals by a signal conditioning signal, so that the wired connection between the sensing unit 110 and the processing module 200 can be converted into a wireless connection, thereby reducing the connection length of the wiring and simplifying the wiring. Further, 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. Therefore, the rigid reinforcement plate can be made unnecessary, the reinforcement process can be omitted, roll processing becomes easy, material and process costs can be saved, and processing efficiency can be improved. At the same time, the convenience during the user's use and assembly is greatly improved, and the function expansion of the sensing module is convenient. Further, since the first coil and the second coil can transmit energy by wireless coupling, in the sensing module, the energy wirelessly received directly by the first coil 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, thereby simplifying the structure of the sensing module and further simplifying the overall structure of the diaper.

[0033] In one embodiment, when the sensing unit 110 includes a plurality of sensors, the signal conditioning chip 120 is provided with a plurality of sensing channel interfaces, and each of the sensing channel interfaces is respectively connected to a corresponding one of the sensors. As can be understood, the sensing channel interface may be designed as required, and thus can be easily adapted to the situation where the number of sensors increases. Further, since the volume of the signal conditioning chip 120 is small, adding a sensing channel interface does not have a great impact on the occupied space of the entire device. As can be understood, when the number of sensors increases to detect more data, compatibility can be achieved only by changing the connection relationship between the sensors and the sensing channel interfaces, the method is simple and easy to implement, which is more advantageous for expanding the functions of the metabolite detection device.

[0034] In one embodiment, the signal conditioning chip 120 is provided with an updatable signal conditioning algorithm, and the signal conditioning algorithm is installed corresponding to the types of the plurality of sensors in the sensing unit 110. That is, by only updating the signal conditioning algorithm in the signal conditioning chip 120, a more abundant signal conditioning function can be realized. Therefore, there is no need to update the hardware structure of the signal conditioning chip 120, and the update of the product can be completed only by performing a simple software algorithm update.

[0035] In one embodiment, the signal conditioning chip 120 is further arranged with pre-set identity information. Correspondingly, the signal conditioning chip 120 has a storage function of recording the identity information of each diaper. The identity information includes, but is not limited to, information such as the ID information of the diaper. When the signal conditioning chip 120 transmits and sends a plurality of the conditioning signals to the first coil 130, the signal conditioning chip 120 further transmits and sends the identity information to the first coil 130 for the processing unit to establish a mapping relationship between the metabolite information and the identity information. In this embodiment, the processing module 200 can determine the correspondence between the metabolite information and the signal conditioning chip 120. Furthermore, when the correspondence between the identity information of the signal conditioning chip 120 and the user usage information is established, the user name corresponding to each metabolite information, the wearing time of the diaper, etc. 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, in response to the data acquisition command, returns the conditioning signal to the data processing unit 220. As can be understood, the user needs to open the APP of the mobile terminal and inquire about the current usage status of the diaper in order to determine whether the diaper needs to be changed. Therefore, by installing the above function, real-time data can be acquired, thereby providing accurate information to the user and improving the user experience.

[0037] Figure 2 is a schematic diagram of a sensor in one embodiment (Part 1). Referring to Figure 2, in one embodiment, the sensing unit 110 includes a plurality of humidity sensors, and all of the plurality of humidity sensors are installed on the base material of the sensing layer 14. The base material is a flexible material that conforms to the user's body and has conductive wiring embedded therein for transmitting the sensing signals of each sensor to the base material. The plurality of humidity sensors are respectively provided at different detection points on the metabolite diffusion path, and each of the humidity sensors detects the humidity at the detection point and generates a corresponding humidity sensing signal. The number of humidity sensors may be from 5 to 10, and specifically, it can be determined according to the size of the diaper. The data processing unit 220 further determines the types of metabolites including liquid metabolites and non-liquid metabolites based on the humidity sensed by each of the humidity sensors. Specifically, the processing module 200 can obtain the increasing state information based on the detection results of each sensor and determine the types of metabolites based on the increasing state information. The increasing state information characterizes the increasing situation over time of the detection results at each detection point, and can include, for example, the humidity increasing rate, the maintaining time maintained within a preset humidity range after the humidity increases, the situation maintained within a preset temperature range after the humidity increases, and the like.

[0038] As an example, the processing module 200 further determines that the type of metabolite is a liquid metabolite when the humidity increasing rate at at least one detection point is greater than the speed threshold. The speed threshold may be determined based on the empirical value of the humidity increasing 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 when the maintaining time at at least one detection point is greater than the first time threshold, and / or determines that the type of metabolite is a liquid metabolite when the maintaining time at any detection point is less than the second time threshold. It is determined to be a substance. The semi-solid metabolite refers to feces with liquid in the metabolite, and may be, for example, soft feces. As can be understood, the first time threshold may be determined based on the normal continuous urination time of the user, and may be, for example, longer than the longest urination time of the user. Since the liquid metabolite is quickly absorbed by the core layer of the diaper after being discharged, its humidity may only be maintained in the case of continuous urination. The semi-solid metabolite has liquid such as the liquid in the metabolite, and the liquid in the metabolite therein is not quickly and completely absorbed by the core layer of the diaper, so the humidity at the detection point is maintained for a certain period of time. When the maintenance time of at least one detection point exceeds the first time threshold, that is, exceeds the normal urination time of the user, the maintenance of the humidity at the detection point is due to the semi-solid metabolite rather than the urination situation. Therefore, at this time, it can be determined that the type of the metabolite is a semi-solid metabolite. FIG. 3 is a diagram showing the humidity change graph of the semi-solid metabolite of an embodiment. Referring to FIG. 3, here, graph l1 is a time change graph, and graph l2 is a humidity value change graph of the semi-solid metabolite. The liquid metabolite may be, for example, the liquid in the metabolite, blood, etc. The second time threshold may be determined based on the normal continuous urination time of the user, and may be, for example, less than or equal to the longest urination time. As can be understood, when the maintenance time of at least one detection point is less than the first time threshold, that is, less than the normal urination time of the user, it indicates that the maintenance of the humidity at the detection point is due to the urination situation. Therefore, at this time, it can be determined that the type of the metabolite is a liquid metabolite. FIG. 4 is a diagram showing the humidity change graph of the liquid metabolite of an embodiment. Referring to FIG. 4, graph l3 is a time change graph, and graph l4 is a humidity value change graph of the liquid metabolite. The first time threshold and the second time threshold may be equal.

[0039] FIG. 5 is a schematic diagram of a sensor according to an embodiment (Part II). Referring to FIG. 5, in one embodiment, the sensing unit 110 includes at least one temperature sensor provided on the metabolite diffusion path, and the temperature sensor detects the temperature of 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 temperature sensed by the temperature sensor.

[0040] Specifically, the increasing state information may further include the duration maintained within a preset temperature range after the humidity increases. When the increasing state information of at least one humidity detection point satisfies the preset conditions and at the same time the temperature of the adjacent temperature detection point gradually decreases, the processing module 200 determines that the type of metabolite is a semi-solid metabolite. As can be understood, when 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 the humidity is maintained within a certain range after excretion, and the temperature gradually decreases after excretion, and it does not continuously rise or be maintained within a certain temperature range like continuous urination. Therefore, for a certain detection point, when the humidity of the detection point is maintained within a preset humidity range after increasing and at the same time the temperature of the detection point gradually decreases, it can be determined that the type of metabolite is a semi-solid metabolite.

[0041] In one embodiment, the data processing unit 220 further determines a target number, which is the number of detection points where the humidity is greater than a second humidity threshold based on the humidity, and determines the metabolic amount based on the target number. The second humidity threshold may be the humidity of the core layer of the diaper when the liquid metabolite is excreted into the core layer of the diaper. As can be understood, when the humidity of the detection point is greater than the second humidity threshold, it indicates that the detection point has a liquid metabolite. By reasonably setting the distance between each detection point, the number of detection points in contact with the liquid metabolite corresponds one-to-one to the metabolic amount, and thus the corresponding metabolic amount can be obtained based on the number of detection points.

[0042] FIG. 6 is a schematic diagram of the positions of the humidity sensors in one embodiment. Referring to FIG. 6, each humidity sensor is installed in a one-to-one correspondence with humidity detection points A, B, C, D, E, F, and G respectively. Based on each detection point, the penetration regions L1 to L4 can be demarcated, where the area of the penetration regions L1 to L4 increases sequentially. When only one detection point comes into contact with the liquid excrement, the liquid excrement is located within region L1, and the metabolic amount corresponding to region L1 may be 20 ml. When three detection points come into contact with the liquid excrement, the liquid excrement is located within region L2, and the metabolic amount corresponding to region L2 may be 40 ml. Similarly hereinafter, the metabolic amount corresponding to region L2 may be 40 ml, and the metabolic amount corresponding to region L4 may be 120 ml. Therefore, in this embodiment, the corresponding metabolic amount can be determined based on the target number, and this method is simple and can effectively measure the metabolic amount.

[0043] In some embodiments, in order to determine the metabolic amount, by obtaining the excretion time of the liquid metabolites in the user's excretion, the metabolic amount can be further determined in combination with the excretion volume per unit time. The excretion time is the time interval between the time when the user starts excretion and the time when the user ends excretion. The time when the user starts excretion can be characterized by the time when the humidity at the urine detection point of the user increases. Since the liquid excrement is rapidly absorbed after being discharged, when the excretion stops, the humidity at the detection point decreases. Therefore, the time when the excretion ends can be characterized by the time when the humidity at the urine detection point of the user decays. Since the humidity at the increase time detection point increases rapidly, it can be determined based on whether the increase rate of the humidity at the target detection point reaches the increase threshold value. The humidity at the decay time detection point decays rapidly, and therefore, it can be determined based on whether the decay rate reaches the decay threshold value. The collected humidity can have a timestamp, and based on this, the increase time and the decay time can be determined.

[0044] In one embodiment, the temperature sensor further senses the temperature of at least the temperature detection points at the user's defecation position and transmits it to the processing module 200 by the signal conditioning chip 120. At least one sensor is installed at the temperature detection point to sense the humidity of the temperature detection point. The processing module 200 further determines that the type of metabolite is solid metabolite when the temperature of the temperature detection point changes in a rising temperature and the humidity of the adjacent humidity detection point is less than the first humidity threshold. As can be understood, the first humidity threshold may be less than or equal to 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 of the first detection point changes in a rising temperature, it indicates that there is a metabolite at the first detection point. At the same time, if the humidity of the first detection point is less than the first humidity threshold, it indicates that it is a solid metabolite, and the solid metabolite may be, for example, dry feces.

[0045] In one embodiment, the temperature sensor further detects the temperatures of a plurality of detection points on the core layer of the diaper corresponding to each excretion location of the user in the worn state of the diaper. 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 when each detection point changes in a rising temperature. Specifically, when the temperature diffusion information sequentially changes in a rising temperature from the detection point at the urination position to the detection point at the defecation location, it is determined that the type of metabolite is liquid metabolite. When the temperature diffusion information sequentially changes in a rising temperature from the detection point at the defecation location to the detection point at the urination position, it is determined that the type of metabolite is non-liquid metabolite. As can be understood, based on the excretion position and diffusion situation of the metabolite, the specific type of metabolite can be determined. The liquid metabolite may include liquid or blood in the metabolite, and the non-liquid metabolite may include solid metabolites such as dry feces, and may also include semi-solid metabolites such as soft feces.

[0046] FIG. 7 is a schematic diagram of a sensor according to an embodiment (Part Three). Referring to FIG. 7, in one embodiment, the sensing unit 110 further includes a liquid-phase metabolite sensor. The liquid-phase metabolite sensor is provided in the biochemical reaction region of the diaper, and detects the liquid flowing from the liquid siphon passage of the diaper into the biochemical reaction region 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, in order to ensure the detection of a plurality of metabolites and be free from the influence of droplet flow paths and mutual signals, the liquid-phase metabolite sensor is designed with separate liquid siphon passages and biochemical reaction regions. Substances that can be detected include, but are not limited to, pH value, glucose, dopamine, uric acid, ascorbic acid, galactose, ketone bodies, white blood cells, proteins, congestion, K+ ions, Na+ ions, iodine ions, calcium ions, iron ions, zinc ions, nitrite, etc. Specifically, FIG. 8 is a schematic cross-sectional view of a liquid-phase metabolite sensor according to an embodiment. Referring to FIG. 8, the sensing material layer of the liquid-phase sensor is provided at each detection point on the substrate, and the metabolite generates a specific reaction to generate an electrical signal. Between two adjacent sensing material layers, a separator is installed to construct a siphon passage separating the adjacent sensing material layers in order to confine the liquid in the metabolite. On the separator, a hydrophilic membrane layer is provided to absorb the liquid in the metabolite and guide the liquid into the siphon passage. In the embodiment shown in FIG. 8, the siphon passage inlet for liquid-phase component analysis is achieved by perforating the hydrophilic membrane layer. As can be understood, in order to ensure that the liquid in the metabolite in the reaction region is sufficient within the detection time for liquid-phase component analysis, it is necessary to establish a stable reaction region. Otherwise, the liquid in the metabolite may be absorbed by the core layer of the diaper, which may not meet the requirements of biochemical detection. The above structure provides a stable reaction region, and the liquid in the metabolite enters the reaction region by siphon action and is detected by the sensing material layer of the reaction region, thereby realizing 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 confinement structure that coats the gas-phase metabolite sensor. The gas confinement structure confines the gas in the metabolite, and the gas-phase metabolite sensor detects the confined gas to generate a corresponding gas-phase biochemical sensing signal. The data processing unit 220 further obtains gas-phase biochemical information corresponding to the gas-phase biochemical sensing signal. Similar to the siphon passage, the gas confinement structure can establish a stable reaction region, thereby ensuring that the gas in the reaction region is relatively stable within the detection time. Otherwise, the gas in the metabolite will volatilize and cannot meet the requirements of biochemical detection. The above structure provides a stable reaction region, where the gas in the metabolite is fixed in the reaction region by the gas confinement structure and detected by the sensing material layer in the reaction region, thereby realizing gas-phase analysis. The gas-phase analysis substances 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 according to an 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 a startup operation input by a user, generates a corresponding startup signal, and transmits the startup signal to the data processing unit 220. When the processing module 200 is placed in the storage bag, the startup signal causes the processing module 200 to automatically detect the sensing module 100 and transmit the startup signal to the sensing module 100, establishing communication with the sensing module 100, thereby enabling the acquisition of information such as the ID information of the sensing module 100, the production and manufacturing time, the placement information, and whether it has been used.

[0051] Embodiments of the present application further provide a diaper. FIG. 10 is a schematic cross-sectional view of a diaper according to an embodiment (Part One). Referring to FIG. 10, the diaper includes a surface layer 11, a bottom layer 12, at least one core layer 13, and a sensing layer 14. One core layer 13 is shown in the figure. The surface 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 provided between the surface layer 11 and the bottom layer 12. Similar to the metabolite detection device described above, the core layer 13 is also called an absorption layer and absorbs metabolites. The sensing layer 14 is provided between the surface layer 11 and the bottom layer 12, and at least one core layer 13 is provided between the sensing layer 14 and the bottom layer 12. For example, when the diaper includes three core layers 13 stacked in sequence, the sensing layer 14 may be installed between the first core layer 13 and the surface layer 11, or between the first core layer 13 and the second core layer 13, or 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 is not limited in this embodiment. The sensing module 100 in the metabolite detection device is provided in the sensing layer 14, that is, the sensing unit 110, the signal conditioning chip 120, and the first coil 130 in the metabolite detection device are all provided in the sensing layer 14. Further, the processing module 200 in the metabolite detection device is provided outside the bottom layer 12, that is, the second coil 210 and the data processing unit 220 in the metabolite detection device are both provided outside the bottom layer 12. In this embodiment, the processing module 200 is installed on the side away from the user's skin and may be used to replace the processing module 200 at any time, or metabolites may flow into the processing module 200 to affect the operation of the processing module 200.

[0052] Continuing to refer to FIG. 10, in one embodiment, a part of the core layer 13 is installed in the coupling path between the first coil 130 and the second coil 210 in the metabolite processing device. The processing unit further obtains the electromagnetic coupling efficiency on the coupling path and obtains the metabolite absorption amount of the core layer 13 based on the electromagnetic coupling efficiency. As can be understood, the moisture absorption state of the core layer 13 affects the electromagnetic coupling efficiency, and thus can also be used for metabolite amount determination and the necessity of diaper replacement by the designed algorithm.

[0053] FIG. 11 is a schematic cross-sectional view of a diaper in one embodiment (Part II). 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 processing device. As can be understood, 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 avoiding the case where the connection between the first coil 130 and the second coil 210 becomes unstable or is disconnected when the diaper is not replaced for a long time. Therefore, in this embodiment, by installing the above structure, the reliability of communication can be effectively ensured.

[0054] In one embodiment, the diaper further includes a storage bag. The storage bag is connected to the outside of the bottom layer 12, houses the processing module 200, an opening is provided in the storage bag, a switch structure is provided at the opening, the switch structure exposes the opening when lifted, and the processing module 200 can be taken in and out through the opening, and the switch structure further closes the opening when closed to prevent the processing module 200 from slipping out during operation. Specifically, when the user replaces the diaper, the processing module 200 is attached to the storage bag of the new diaper, thereby reducing the user's usage cost. Furthermore, wired connection Compared with the [previous] method, when detaching and attaching the diaper of the embodiment of the present application, it is not necessary to perform operations such as aligning the connection lines, thereby improving the convenience of detachment and attachment. In addition, through the software function upgrade of the processing module 200, the diaper can support richer detection and analysis functions. As understood, based on the wireless connection method, after the software function upgrade, there is no need to improve the hardware structure such as the pins and connection lines of the processing module 200, and without excessively increasing the cost, the functional expandability of the processing module 200 can be effectively improved. In this embodiment, by installing the storage bag, it is ensured that the position of the processing module 200 does not move excessively, thereby ensuring the reliability of the communication process. In addition, by installing an opening with a switch mechanism in the storage bag, it is avoided that the processing module 200 naturally slips out of the storage bag, thereby further improving the reliability.

[0055] In one embodiment, the storage bag is provided at the corresponding position of the first coil 130 in the sensing module 100 in order to minimize the coupling path between the second coil 210 and the first coil 130. By the above installation method, the transmission efficiency between the two coils can be maximized, thereby improving the communication speed of the communication process.

Referring to FIG. 12, the care system includes a mobile terminal and the above-mentioned diaper. The mobile terminal includes a first wireless transmission unit. 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 the data processing unit 220, and transmits the metabolite information to the first wireless transmission unit of the mobile terminal and receives a control command from the first wireless transmission unit. Taking the processing module 200 in the diaper as the host, the wireless transmission unit transmits the monitoring data to the APP of the mobile terminal. The APP of the mobile terminal acquires the data transmitted from the processing module 200, processes the data, and then displays it on the UI screen of the APP, realizing functions such as viewing and feedback by the user.

The mobile terminal further transmits the metabolite information to the cloud server, and the cloud server stores and analyzes the received metabolite information. The APP of the mobile terminal can also transfer the acquired data to the cloud, thereby realizing functions such as cloud storage of data, and more abundant analysis and application determination, thereby improving the flexibility in the use process.
