[0020] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , wherein, Figure 1Block diagram of the first embodiment of an intelligent disposable diaper provided by the present invention; Figure 2 is Figure 1 Schematic diagram of the structure of the pants body shown; Figure 3 is Figure 2 Schematic cross-sectional structure diagram of the liquid-permeable surface layer and the liquid-impermeable bottom layer shown; Figure 4 is Figure 3 Schematic block diagram of the radio frequency identification tag shown; Figure 5 is Figure 1 Schematic block diagram of the reader / writer shown. An intelligent disposable diaper includes: a pants body 1, a reader / writer 2, and a user terminal 3. The pants body 1 is wirelessly connected to the reader / writer 2, and the reader / writer 2 is wirelessly connected to the user terminal. The pants body 1 includes an elastic waistband 10, a support sheet 11, a liquid-impermeable bottom layer 12, a liquid-permeable surface layer 13, an absorption layer 14, and a radio frequency identification tag 15. The liquid-permeable surface layer 13 is disposed on top of the liquid-impermeable bottom layer 12, the absorption layer 14 is disposed between the liquid-impermeable bottom layer 12 and the liquid-permeable surface layer 13, and the radio frequency identification tag 15 is disposed at the bottom of the absorption layer 14.

[0021] The radio frequency identification tag 15 is provided with a loop antenna 150, a chip capacitor 151, and an integrated circuit 152. The loop antenna 151 is used for receiving and transmitting signals. The chip capacitor 151 cooperates with the loop antenna 150 to enable the radio frequency identification tag 15 to operate at a specific frequency. The integrated circuit 152 is used for storing tag information. The radio frequency identification tag 15 sends the stored tag information to the reader / writer 2 through the loop antenna 150.

[0022] The reader / writer 2 includes a radio frequency module 20, a reader / writer antenna 21, and a control unit 22. The radio frequency module 20 is used for transmitting a reading signal, performing wireless communication with the radio frequency identification tag 15 through the reader / writer antenna 21, and receiving the response signal of the radio frequency identification tag 15. The control unit 22 is used for processing and decoding the received signal, and sending the decoded tag information and related data to the user terminal 3.

[0023] The user terminal 3 includes an information receiving module, an information analysis module, and a reminder module. The information receiving module is used for receiving the tag information and related data sent by the reader / writer 2. The information analysis module is used for analyzing the received information to determine whether the signal of the radio frequency identification tag 15 is abnormal. When the information analysis module determines that the signal is abnormal, the reminder module sends a reminder to the caregiver to replace the disposable diaper in a timely manner.

[0024] The support piece 11 is arranged at the bottom of the elastic waistband 10, and the bottom of the liquid-impermeable bottom layer 12 is arranged on the inner side surface of the support piece 11.

[0025] The material of the liquid-permeable surface layer 13 is non-woven fabric, including but not limited to hot air / spunbond / punched film. The material of the liquid-impermeable bottom layer 12 is PE film / spunbond non-woven fabric / pe spunbond composite film. The material of the absorption layer 14 is fluff pulp / superabsorbent resin / superabsorbent resin composite non-woven fabric or dust-free paper; The proportion of each layer of material in the total material: the proportion of the liquid-permeable surface layer 13 is 0.2% - 15%, the proportion of the liquid-impermeable bottom layer 12 is 3% - 35%, and the proportion of the absorption layer 14 is 20% - 97% The proportion of the material of each layer in the material of that layer: the proportion of the materials of the liquid-impermeable bottom layer 12 and the liquid-permeable surface layer 13 are both non-woven fabric 0 - 100%, PE film 0 - 100% The proportion of wood pulp in the material of the absorption layer 14 is 0% - 100%, the proportion of superabsorbent resin is 0% - 70%, the proportion of non-woven fabric is 0% - 60%, and the proportion of dust-free paper is 0% - 30%; The reader antenna 21 in the reader 2 communicates with the loop antenna 150 in the radio frequency identification tag through electromagnetic coupling; the reader outputs a radio frequency signal, and the radio frequency identification tag 15 receives the signal through the loop antenna 150. The radio frequency identification tag 15 detects the DC signal of the detector circuit integrated in the chip to obtain energy and drive the chip. The data communication between the reader 2 and the radio frequency identification tag 15 generally uses amplitude shift keying modulation with a frequency of 13.56 MHz; First, the loop antenna 150 is formed on the tag by printing or other means. Subsequently, the chip and the chip capacitor 151 are placed on the same tag. The chip capacitor 151 on the tag can also be made by printing. Then, a tag bonding station is added to the disposable diaper production line, and the tag is compounded on the liquid-impermeable bottom layer 12 of the disposable diaper by hot melt adhesive or other means such as pressing. When an abnormal signal appears on the tag, the abnormal signal is sent to the reader 2 through the loop antenna 150, and the reader 2 transmits the signal to the application program for the caregiver to process.

[0026] The working principle of an intelligent disposable diaper provided by the present invention is as follows: When the user excretes, the liquid in the excrement passes through the liquid-permeable surface layer 13 and is absorbed and stored by the absorption layer 14. As the amount of liquid absorbed by the absorption layer 14 increases, its humidity changes, which in turn affects the working environment of the radio frequency identification tag 15 in close contact with it. Due to the infiltration of moisture with ions, the radio frequency identification tag 15 has a short circuit phenomenon, resulting in an abnormal signal sent by it; The RF module 20 in the reader / writer 2 continuously emits a reading signal, which propagates into the surrounding space through the reader / writer antenna 21. When the reader / writer antenna 21 receives an abnormal response signal from the RFID tag 15, it transmits the signal back to the RF module 20, and then the control unit 22 processes and decodes the received signal. The control unit 22 can extract key information from the complex signal, including the tag information stored in the RFID tag 15 and other relevant data, and sends the decoded information to the user terminal 3; After the information receiving module of the user terminal 3 receives the tag information and related data sent by the reader / writer 2, the information analysis module starts to deeply analyze this information. The information analysis module compares the received signal with the preset normal signal standard. When it determines that the signal of the RFID tag 15 is abnormal, it immediately triggers the reminder module to work. The reminder module will use various methods, such as emitting a sound alarm, vibrating or popping up a notification window, etc., to remind the nursing staff to replace the disposable diaper in time, ensuring that the nursing staff can quickly know and take corresponding actions.

[0027] Compared with the related technologies, an intelligent disposable diaper provided by the present invention has the following beneficial effects: Through the collaborative work of the RFID tag 15, the reader / writer 2 and the user terminal 3, the usage status of the diaper can be monitored in real time and accurately. Once it is detected that the excrement has soaked through, the system will immediately issue a reminder, allowing the nursing staff to replace the diaper in time. This effectively avoids the user's skin being in a wet and dirty environment for a long time and reduces the risk of skin damage; Through the automatic monitoring and reminder function, the nursing staff does not need to pay attention all the time. They only need to perform the replacement operation after receiving the reminder, saving labor and time costs and reducing the nursing difficulty. Embodiment

[0028] Please refer to the Figures 6 - 9 second embodiment of the present invention, which also provides another intelligent disposable diaper.

[0029] In an optional manner of this embodiment, the intelligent disposable diaper may include the reader / writer 2 and the user terminal 3; the intelligent disposable diaper further includes: a side pocket 4, a binding strap 5 and a storage member 6. The side pocket 4 is arranged on the side of the pants body 1, one end of the binding strap 5 is arranged on the side of the pants body 1, and the storage member 6 is arranged on the inner side of the side pocket 4.

[0030] One end of one side of the binding strap 5 is provided with a first adhesive piece 51, and the first adhesive piece 51 is adhered to the side of the side pocket 4.

[0031] The storage member 6 includes a bag body 61, a folding piece 62, and a second adhesive piece 63. The folding piece 62 is disposed at the top of the bag body 61, and the second adhesive piece 63 is disposed on the side of the folding piece 62.

[0032] The folding piece 62 and the opening of the bag body 61 have the same length, and the folding piece 62 is used to block the opening of the bag body 61.

[0033] The bundling strap 5 is disposed at the opening at the top of the side pocket 4.

[0034] After bundling the disposable diapers with the bundling strap 5, the first adhesive piece 51 can also be adhered to the disposable diapers to prevent the bundled disposable diapers from coming apart. The bundling strap 5 has a certain degree of extensibility, which facilitates stretching and winding around the disposable diapers. Before use, the surface of the second adhesive piece 63 has a film. When in use, the user needs to first tear off the film and then use the second adhesive piece 63 to adhere it to the bag body 61.

[0035] In another alternative embodiment of the present invention, the intelligent disposable diaper may not include the reader 2 and the user terminal 3, as long as it does not interfere with the other components of the intelligent disposable diaper and can remind when the trouser body 1 is wet.

[0036] In yet another alternative embodiment of the present invention, the intelligent disposable diaper may also include an electronic device or functional module in the prior art to replace the reader 2 and the user terminal 3 and achieve the same functions of the above modules. As long as the electronic device or functional module in the prior art does not interfere with the other components of the intelligent disposable diaper and can remind when the trouser body 1 is wet.

[0037] The working principle of the intelligent disposable diaper provided by the present invention is as follows: In an actual use scenario, when it is necessary to change the disposable diaper, the user or caregiver first removes the first adhesive piece 51 from the side pocket 4, and then takes out the storage member 6 from the side pocket 4. Subsequently, the trouser body 1 is wound with the bundling strap 5 to effectively prevent it from coming apart and avoid leakage of excrement and causing pollution. The wound and fixed trouser body 1 is placed into the bag body 61. The internal material of the bag body 61 has a certain anti-leakage performance, further ensuring hygiene. After that, turn down the folding piece 62. The length of the folding piece 62 is exactly the same as the opening of the bag body 61, ensuring a good sealing effect. At this time, paste the second adhesive piece 63 on the side of the bag body 61 to tightly seal the storage member 6, effectively preventing the smell from spreading, avoiding contact between the diaper and the outside world, and reducing the risk of bacteria transmission.

[0038] Compared with the related art, an intelligent disposable diaper provided by the present invention has the following beneficial effects: Through the cooperation of structures such as the side pocket 4, the binding strap 5, and the storage member 6, after changing the diaper, the diaper can be stored on the inner side of the bag body 61, and the opening of the bag body 61 can be sealed. In this way, not only can the escape of odor be avoided, but also the whole nursing process can be made more hygienic.

[0039] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
