Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of paper diapers, in particular to an intelligent paper diaper with monitoring function, a monitoring system and a monitoring method. BACKGROUND

[0002] As a widely used sanitary product for infants, the elderly and special care scenarios, the main function of paper diapers is to absorb and lock urine through the internal absorbent material, to keep the user's skin dry and provide a comfortable wearing experience. In recent years, with the development of intelligent technology, paper diapers with urine monitoring function have gradually attracted attention. These intelligent paper diapers usually integrate sensors or conductive materials on the basis of traditional paper diapers, detect the penetration of urine to determine whether a urination event has occurred, and transmit relevant information to caregivers or guardians through electrical signals or wireless communication. Such products have improved the timeliness of care to some extent, especially in the field of infant care, elderly care or medical rehabilitation, reducing the care burden and improving the quality of life of users.

[0003] However, the existing paper diapers with urine monitoring function still have certain limitations in actual application. The current monitoring technology mainly focuses on detecting whether urine has penetrated the paper diaper, i.e., only determining whether a urination event has occurred, but cannot further distinguish the amount of urine or the absorption state of the paper diaper. This single monitoring method cannot meet the actual care needs, because the amount of urine directly affects whether the paper diaper needs to be replaced immediately and whether there is a risk of leakage due to the absorption limit being reached. In addition, the existing technology usually lacks a hierarchical detection function for the amount of urine, which cannot provide caregivers with more accurate replacement timing prompts, which may lead to premature or late replacement of paper diapers, affecting the comfort of users or increasing the cost of care. Therefore, there is an urgent need for an intelligent paper diaper that can realize hierarchical monitoring of the amount of urine to further optimize care efficiency and user experience. SUMMARY

[0018] Secondly, urine is absorbed by the paper diaper body and gradually diffuses, and when the first electrode line sequentially forms a conductive path with the second electrode line through urine, the monitoring sensor detects and records the electrical signal change generated by each first electrode line.

DETAILED DESCRIPTION

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship. Example 1

[0043] like Figures 1 to 14 As shown, the smart diaper with monitoring function includes: a diaper body 1, a sensing wire group 2, and a monitoring sensor 3; the sensing wire group 2 includes at least two first electrode wires 21 and one second electrode wire 22 of different lengths, and the first electrode wire 21 and the second electrode wire 22 are respectively connected to the monitoring sensor 3; wherein, the first electrode wire 21 is embedded inside the diaper body 1 and is spaced apart from the second electrode wire 22, so that when urine permeates, the first electrode wire 21 and the second electrode wire 22 are sequentially electrically connected through the urine according to their length differences. The monitoring sensor 3 detects changes in electrical signals according to the order of connection to determine the degree of urine permeation in the diaper body 1.

[0044] In the above structure, because the lengths of the first electrode wires 21 are different from each other, when they are embedded inside the diaper body 1, they can form a distribution relationship from long to short. In this way, as urine diffuses and permeates, the longer electrode wires first come into contact with the urine and form a conductive path with the second electrode wire 22, while the shorter electrode wires only connect with the second electrode wire 22 as the urine further permeates. This distribution method creates a tiered arrangement of the electrode wires in the structure, thereby ensuring the sequential and graded characteristics of urine contact.

[0045] In terms of mechanism, urine, as a conductive medium, can form an electric signal path between the first electrode line 21 and the second electrode line 22 when it permeates to the position of the first electrode line 21, and the monitoring sensor 3 can make a judgment after detecting the signal. With the increase of urine, more first electrode lines 21 of different lengths will be sequentially turned on, and the turn-on sequence of each electrode line will cause a change in the electric signal. The monitoring sensor 3 can determine the diffusion range and penetration degree of urine in the diaper body 1 by identifying the order and number of the electric signal, thereby realizing real-time monitoring of the urination process. Thus, the entire device realizes the cooperation between the electrode line structure and the monitoring sensor 3 without affecting the normal use function of the diaper body 1, and ensures the sensitivity and reliability of the monitoring.

[0046] In the present embodiment, the number of the first electrode lines 21 is three, and the three first electrode lines 21 are arranged in sequence along the longitudinal direction of the diaper body 1 while being spaced apart from the second electrode line 22. Since the three first electrode lines 21 are different in length, a gradient distribution from top to bottom or from inside to outside can be formed in the diaper body 1, and when urine gradually spreads from the discharge point to the surrounding, it will inevitably contact different first electrode lines 21 in sequence according to the arrangement order of the electrode lines, thereby ensuring the step-by-step nature of the penetration detection in terms of structural layout.

[0047] In the present embodiment, the three first electrode lines 21 correspond to the first, second and third levels of urine penetration degree, respectively. Specifically, when urine first permeates to the longest first electrode line 21, the electrode line and the second electrode line 22 first form a closed loop through urine conduction, and the monitoring sensor 3 identifies the occurrence of the electric signal, determining that this time corresponds to the first level of penetration. When urine continues to increase and spread to the first electrode line 21 of medium length, the second electrode line is turned on, and the monitoring sensor 3 detects a new change in the electric signal, determining that the penetration degree has reached the second level. With further increase of urine, the shortest first electrode line 21 is covered and turned on by urine, and the monitoring sensor 3 detects a change in the electric signal again, determining that the urine penetration degree reaches the third level. Thus, the three first electrode lines 21 can realize accurate identification and judgment of the urine amount in stages according to the signal sequence corresponding to the length difference.

[0048] In the embodiment, the sensing line group 2 further comprises a connecting portion 23. The connecting portion 23 is arranged at the end region of the sensing line group 2, connected with the first electrode line 21 and the second electrode line 22, and is provided with a first conductor 231 and a second conductor 232 on the surface thereof. The first conductor 231 is connected with the first electrode line 21, and the second conductor 232 is connected with the second electrode line 22, and the first conductor 231 and the second conductor 232 are respectively connected with the positive electrode and the negative electrode of the monitoring sensor 3. Through this connection mode, the first electrode line 21 and the second electrode line 22 can form a stable corresponding relationship in the circuit, and when urine as a conductive medium causes communication between the two, the current can be transmitted to the monitoring sensor 3 through the first conductor 231 and the second conductor 232, so that the monitoring sensor 3 can capture the change of the electrical signal in time. Since the first conductor 231 and the second conductor 232 respectively undertake the leading-out function of the positive electrode and the negative electrode, the electrical connection relationship is clear, which can avoid interference or confusion in signal transmission and ensure the stability and accuracy of the electrical signal in the transmission process. In this way, a complete closed circuit system is formed between the electrode line and the monitoring sensor 3, which provides a reliable electrical basis for real-time judgment of the degree of urine penetration.

[0049] In the embodiment, the smart diaper with monitoring function further comprises a response device 6, which is configured to trigger an audible response or a light-emitting response according to the degree of urine penetration detected by the monitoring sensor 3. Specifically, when the monitoring sensor 3 detects that the first electrode line 21 and the second electrode line 22 are conductive due to urine and generate an electrical signal, the electrical signal will be transmitted to the response device 6 for signal recognition and response control. When the degree of penetration reaches different levels, the response device 6 can output different forms of prompt information, for example, triggering an audible response when initial detection is performed to prompt the caregiver that the user has urinated, and triggering a light-emitting response when the degree of penetration is further deepened to indicate that the diaper needs to be replaced in a more intuitive way.

[0050] In the embodiment, the second electrode line 22 is S-shaped. By designing the second electrode line 22 to be S-shaped, a larger coverage area can be formed inside the diaper body 1, so that the first electrode line 21 can be spaced apart from the second electrode line 22 at multiple positions when it is distributed in the longitudinal direction. In this way, when urine gradually diffuses and penetrates, any first electrode line 21 can be connected with the second electrode line 22 through urine conduction at the corresponding position, thereby improving the sensitivity and reliability of detection. The S-shaped arrangement not only increases the contact probability between the second electrode line 22 and the first electrode line 21, but also prolongs the conduction path in a limited space, ensuring the stability of electrical signal transmission during monitoring and further improving the accuracy of urine penetration detection.

[0051] The intelligent paper diaper with monitoring function can also provide corresponding prompt information according to different urine amounts, thereby effectively guiding nursing personnel or users to replace the paper diaper in time. Compared with the traditional paper diaper, the intelligent paper diaper of the present application significantly improves the real-time performance and accuracy of urine monitoring by integrating the sensing line group 2 and the monitoring sensor 3, and the design of the detachable monitoring sensor 3 further enhances the economy and sustainability of the system, which is suitable for infants, the elderly or people who need special care.

[0052] In the present embodiment, the monitoring sensor 3 is built-in with a battery for providing power support for the entire detection and response process. Due to the structural design of the first electrode line 21 and the second electrode line 22, the first electrode line 21 and the second electrode line 22 are always in an open circuit state when no urine appears, and the monitoring sensor 3 does not receive electrical signal input, thereby avoiding invalid conduction of the circuit. Such design makes the monitoring sensor 3 in a low-power standby mode in a non-working state, and only when urine penetration forms a conductive path, current transmission and detection signals are triggered, thereby significantly reducing the energy consumption of the battery, prolonging the service life and endurance of the whole machine. Through such an open-circuit-conduction working mode, the real-time performance of urine penetration detection is ensured, and the efficiency of power management is also taken into account.

[0053] Further, the monitoring sensor 3 is a micro electrical signal sensor based on conductivity detection, and can specifically select a common low-power conductivity sensor on the market (such as a micro electrode sensor or an electrochemical sensor based on conductivity measurement). Such sensors usually include a microprocessor, a signal amplification circuit and an electrical signal detection module, and can capture and process weak electrical signals with high sensitivity. The monitoring sensor 3 forms a stable electrical connection with the sensing line group 2 in the paper diaper body 1 through a conductive fastener or a plug-in terminal, and has a small size and is suitable for detachable installation on the outside or edge area of the paper diaper body 1, ensuring portability and reusability during use.

[0054] In this embodiment, the diaper body 1 is provided with a first fixing part 11 and a second fixing part 12, which are respectively located at the two side edge regions of the diaper body 1, for fixing the diaper to the waist and leg regions of the user during wearing. The first fixing part 11 is provided with a nylon pile surface 13, which has a soft pile structure and can form a firm adhesion with the nylon hook surface 15 on the fixing belt 14. The second fixing part 12 is connected with the fixing belt 14, which is made of a material with good flexibility, and the end of the fixing belt 14 is provided with a nylon hook surface 15, which can closely adhere to the nylon pile surface 13 to form a reliable fixed connection. This fixing mode ensures that the diaper body 1 can closely fit the body contour of the user during wearing through the adhesion mechanism of the nylon hook surface 15 and the nylon pile surface 13, avoiding slipping or displacement.

[0055] During wearing, the diaper body 1 is put on from under the crotch of the user, and then the first fixing part 11 and the second fixing part 12 are brought close to or in contact with each other by bending the diaper body 1. The operator then adheres the nylon hook surface 15 on the fixing belt 14 to the nylon pile surface 13 on the first fixing part 11, thereby completing the fixing of the diaper body 1. At this time, the first fixing part 11, the second fixing part 12 and the diaper body 1 together enclose a space for the user's legs to pass through, ensuring that the diaper can fit the body after wearing, while providing sufficient flexibility for leg movement. This fixing structure design not only has simple operation, but also can adapt to users of different body types, and through adjusting the adhesion position of the nylon hook surface 15 and the nylon pile surface 13, an individualized fitting effect is achieved, thereby improving the comfort and stability of wearing.

[0056] The internal structure of the diaper body 1 is composed of multiple layers of composite materials, including a non-woven fabric 16, a water absorption layer 17 and an encapsulation layer 18, which respectively undertake different functions to achieve effective absorption and monitoring of urine. The non-woven fabric 16, as the inner layer directly contacting the user's skin, is made of soft, breathable and skin-friendly non-woven fabric material, ensuring the comfort and breathability of the skin contact, while allowing urine to quickly penetrate to the underlying water absorption layer 17. The water absorption layer 17 is located between the non-woven fabric 16 and the encapsulation layer 18 and is composed of high molecular water absorption resin (SAP) and other water absorption materials, which have strong water absorption and water locking capacity, can quickly absorb and lock urine, preventing leakage. The encapsulation layer 18, as the outermost layer of the diaper, is made of waterproof and breathable material, effectively preventing urine from leaking from the water absorption layer 17, while maintaining a certain breathability to improve the comfort of the user. The first electrode wire 21 and the second electrode wire 22 are both laid between the non-woven fabric 16 and the water absorption layer 17, close to the area of the water absorption layer 17, to ensure that urine can quickly contact the first electrode wire 21 and the second electrode wire 22 after penetration, triggering an electrical signal.

[0057] In actual use, when urine is produced, it first rapidly penetrates the water-permeable non-woven fabric 16 into the water-absorbing layer 17. The water-absorbing layer 17 rapidly absorbs and locks the urine through its high-molecular water-absorbing material, avoiding the diffusion or exosmosis of the urine inside the diaper. The first electrode line 21 and the second electrode line 22 located between the non-woven fabric 16 and the water-absorbing layer 17 can timely contact the penetrated urine, form a closed circuit by using the conductivity of the urine, generate an electrical signal, and transmit it to the monitoring sensor 3.

[0058] In the present embodiment, the intelligent diaper with monitoring function further comprises a clamping assembly 4 for clamping the monitoring sensor 3 on the diaper body 1. By arranging the clamping assembly 4, the monitoring sensor 3 can be in a stable fixed state on the diaper body 1, avoiding the displacement of the sensor position due to the bending or movement of the diaper body 1 during use. The clamping action of the clamping assembly 4 on the monitoring sensor 3 ensures that the electrical connection between the sensor and the first electrode line 21 and the second electrode line 22 is reliable, thereby ensuring that the transmission of the electrical signal is not disturbed by the outside world.

[0059] In the present embodiment, the clamping assembly 4 comprises a first clamping part 41, a second clamping part 42, a rotating shaft 43, and a torsional spring 44. The first clamping part 41 and the second clamping part 42 are connected to each other through the rotating shaft 43, the rotating shaft 43 passes through the central parts of both, forming a rotating axis, so that the first clamping part 41 and the second clamping part 42 can rotate relative to each other around the rotating shaft 43. The torsional spring 44 is sleeved on the rotating shaft 43, and its two ends are connected to the first clamping part 41 and the second clamping part 42, respectively. The elastic restoring force of the torsional spring 44 provides a continuous torsional force for the two clamping parts, so that the first clamping part 41 and the second clamping part 42 tend to close when there is no external force, thereby firmly clamping at a predetermined position of the diaper body 1.

[0060] The clamping surfaces of the first clamping part 41 and the second clamping part 42 are designed to be in a shape that matches the outer surface of the diaper body 1, which is a smooth contact surface in the present embodiment, to avoid causing damage to the diaper body 1 or affecting the wearing comfort. The rotating shaft 43, as the core connecting component of the clamping assembly 4, not only provides the rotating freedom of the first clamping part 41 and the second clamping part 42, but also ensures the accuracy and reliability of the clamping action through its stable axial support. The arrangement of the torsional spring 44 enables the clamping assembly 4 to automatically recover to the clamping state during the clamping process.

[0061] In use, the operator presses the first clamping portion 41 and the second clamping portion 42 away from the side of the diaper body 1, causing the two clamping portions to rotate relative to the rotation shaft 43, overcoming the elastic force of the torsion spring 44, and causing the torsion spring 44 to be compressed. At this time, the first clamping portion 41 and the second clamping portion 42 open towards the side of the diaper body 1, forming a clamping space sufficient to accommodate the edge or predetermined clamping area of the diaper body 1. After placing the diaper body 1 in the clamping space, the operator releases the pressing of the first clamping portion 41 and the second clamping portion 42, and the elastic restoring force of the torsion spring 44 drives the two clamping portions to return to the closed state, thereby firmly clamping the diaper body 1. The clamping assembly 4 is usually fixed to the diaper body 1 near the installation position of the monitoring sensor 3 to ensure that the electrical connection point of the sensor and the induction line set 2 does not loosen due to movement or pulling during wearing.

[0062] The clamping assembly 4 works cooperatively through the first clamping portion 41, the second clamping portion 42, the rotation shaft 43 and the torsion spring 44, and the clamping assembly 4 achieves stable fixation of the diaper body 1, ensuring the positional stability of the monitoring sensor 3 during wearing and use, thereby ensuring the continuity and accuracy of urine monitoring.

[0063] The first clamping portion 41 is provided with a sliding groove 411, which provides a sliding path for the first conductor 231 and the second conductor 232, enabling the connection portion 23 to be accurately inserted into the predetermined position. The sliding groove 411 is further provided with a limiting slot 412 for limiting and fixing the first conductor 231 and the second conductor 232 when they are slid to the correct position, thereby ensuring the reliability and stability of the electrical connection.

[0064] The first clamping portion 41 and the second clamping portion 42 form a containing space for accommodating the connection portion 23 and the clamping area of the diaper body 1. In use, the operator presses the first clamping portion 41 and the second clamping portion 42 away from the side of the diaper body 1, causing the two clamping portions to rotate relative to the rotation shaft 43, opening the clamping space. Then, the first conductor 231 and the second conductor 232 of the connection portion 23 are inserted along the sliding groove 411 on the first clamping portion 41, and the first conductor 231 and the second conductor 232 slide in the sliding groove 411 until they reach the position of the limiting slot 412. At this time, the pressing of the first clamping portion 41 and the second clamping portion 42 is released, and the elastic restoring force of the torsion spring 44 drives the two clamping portions to close, causing the first clamping portion 41 and the second clamping portion 42 to exert clamping force on the connection portion 23 and the corresponding area of the diaper body 1, thereby firmly fixing the connection portion 23 in the clamping assembly 4. The inner wall of the limiting slot 412 is adapted to the shape of the first conductor 231 and the second conductor 232, ensuring that the first conductor 231 and the second conductor 232 can be firmly clamped after insertion, avoiding loosening due to vibration or movement.

[0065] The two guide cores inside the limiting clamping groove 412 correspond to the positive and negative electrodes of the monitoring sensor 3 respectively; the two guide cores act as the conduction medium of the electrical signal, and are used to contact the first conductor 231 and the second conductor 232 respectively, directly contact to form a stable electrical connection path. The guide core is further connected to the monitoring sensor 3 and the battery (not marked in the figure) through the internal circuit, providing power support for the monitoring sensor 3, and transmitting the urine detection signal generated by the sensing wire group 2 to the monitoring sensor 3 for processing. The limiting design of the limiting clamping groove 412 not only ensures the accurate alignment between the first conductor 231 and the second conductor 232 and the guide core, but also prevents the first conductor 231 and the second conductor 232 from slipping or detaching during clamping through the buckle structure, thereby avoiding interruption or unstable transmission of the electrical signal. The cooperative design of the sliding groove 411 and the limiting clamping groove 412 makes the insertion and fixing operation of the connecting part 23 simple and efficient, while ensuring the long-term reliability of the electrical connection.

[0066] The sliding groove 411 provides guidance for the first conductor 231 and the second conductor 232, ensuring that they can smoothly and accurately slide into the limiting clamping groove 412, while the limiting clamping groove 412 realizes the physical fixation of the first conductor 231 and the second conductor 232 and the stable transmission of the electrical signal through its geometric structure and the setting of the guide core. When urine triggers the first electrode wire 21, the electrical signal generated is transmitted to the guide core through the first conductor 231 and the second conductor 232 of the connecting part 23, and then transmitted to the monitoring sensor 3 by the guide core for analysis and processing. The limiting function of the limiting clamping groove 412 effectively prevents the first conductor 231 and the second conductor 232 from detaching from the guide core due to external force (such as the movement of the wearer or the deformation of the diaper), ensuring the continuity of the electrical signal transmission and the accuracy of the monitoring results.

[0067] In the present embodiment, two positioning rods 413 are arranged on the first clamping part 41, and the positioning rods 413 are fixedly arranged on the clamping surface of the first clamping part 41 facing the second clamping part 42, in a columnar structure. The end of the positioning rod 413 away from the first clamping part 41 is provided with a piercing part 414, and the tip shape of the piercing part 414 facilitates piercing the material layer of the diaper body 1 during clamping, while ensuring that it will not cause significant damage to the water absorption function or overall structure of the diaper body 1. The clamping assembly 4 realizes accurate positioning and firm fixation on the diaper body 1.

[0068] In the connecting structure of the clamping assembly 4, the positioning plug 413 forms a precise fitting relationship with the receiving hole or groove of the second clamping part 42. When the first clamping part 41 and the second clamping part 42 are closed under the torsional force of the torsion spring 44, the positioning plug 413 is inserted into the receiving structure of the second clamping part 42 along its axial direction, and at the same time, the piercing part 414 pierces through the predetermined area of the diaper body 1, usually the non-absorbent functional area near the edge, to avoid affecting the performance of the absorbent layer 17. The sharp end of the piercing part 414 is designed to smoothly penetrate the multi-layer composite structure of the diaper body 1 (such as non-woven fabric 16 and packaging layer 18), and form a stable anchoring point after being inserted into the second clamping part 42. The length and distribution position of the positioning plug 413 are precisely designed to ensure that the first clamping part 41 and the second clamping part 42 can uniformly apply force during clamping, and through the synergistic effect of the two positioning plugs 413, the anti-displacement ability of the clamping assembly 4 on the diaper body 1 is enhanced.

[0069] In the present embodiment, the second clamping part 42 is provided with a plug hole 421 for accommodating the positioning plug 413, and a locking assembly 5 is arranged in the plug hole 421 for reliably locking the inserted positioning plug 413 to prevent it from accidentally coming off the plug hole 421, thereby ensuring the firm connection of the clamping assembly 4 with the diaper body 1. The locking assembly 5 includes a guide disc 51, two driving discs 52, three clamping blocks 53, a sleeve 54, and a driving arm 55. The guide disc 51 is fixedly installed at the inner position of the plug hole 421 to provide guiding and supporting functions. The two driving discs 52 are fixedly installed on the inner wall of the sleeve 54, and the sleeve 54 is rotatably installed in the plug hole 421, with its end away from the positioning plug 413 penetrating through the plug hole 421 and being fixedly connected with the driving arm 55. The second clamping part 42 is provided with a first limiting piece 422 and a second limiting piece 423 for limiting the rotation range of the driving arm 55. The clamping blocks 53 are located between the two driving discs 52, and each clamping block 53 is provided with a lever 531 penetrating through the arc-shaped driving slot 521 on the driving disc 52, and at its end close to the guide disc 51, a sliding block 532 is fixedly connected, which extends into the guide slot 511 on the guide disc 51 and is slidingly connected therewith.

[0070] The guide disc 51 serves as a fixed reference, and provides a radial sliding path for the slider 532 through the guide groove 511, ensuring that the movement direction of the clamping block 53 is controlled; the arc-shaped drive groove 521 on the drive disc 52 is in sliding fit with the push rod 531, and when the drive disc 52 rotates, the curved shape of the arc-shaped drive groove 521 can convert the rotary motion into radial displacement of the push rod 531; the sleeve 54 serves as a transmission core, converting external operation of the drive arm 55 into synchronous rotation of the drive disc 52; the fixed connection between the drive arm 55 and the sleeve 54 ensures reliable transmission of torque, and the first limiting piece 422 and the second limiting piece 423 define the opening and closing states of the locking assembly 5 by clamping the position of the drive arm 55. The clamping block 53 is connected with the drive disc 52 and the guide disc 51 through the push rod 531 and the slider 532, achieving stable positioning between the two drive discs 52, and the uniform distribution of the three clamping blocks 53 ensures multi-point clamping of the positioning insertion rod 413, improving the uniformity and reliability of the locking.

[0071] In use, when the first clamping part 41 and the second clamping part 42 are closed under the action of the torsional spring 44 to clamp the diaper body 1, the positioning insertion rod 413 passes through the round holes on the guide disc 51 and the drive disc 52, and the diameters of these round holes are designed to be larger than the diameter of the positioning insertion rod 413 to adapt to the non-axial insertion movement of the positioning insertion rod 413, ensuring smooth penetration. Subsequently, the operator actuates the drive arm 55 to rotate to be clamped in the first limiting piece 422, at which time the drive arm 55 drives the sleeve 54 to rotate, the sleeve 54 further drives the two drive discs 52 to rotate synchronously, the arc-shaped drive groove 521 on the drive disc 52 pushes the push rod 531 to move along the guide direction of the guide groove 511, so that the push rod 531 approaches the axis of the drive disc 52; the sliding connection of the slider 532 in the guide groove 511 prevents the rotation of the push rod 531, ensuring the linear stability of the movement; the displacement of the push rod 531 drives the three clamping blocks 53 to approach each other, exerting a clamping force on the positioning insertion rod 413 to achieve locking. Since the positioning insertion rod 413 directly penetrates the diaper body 1, this locking connection further prevents displacement of the clamping assembly 4 relative to the diaper body 1, thereby maintaining stable connection between the connection part 23 and the clamping assembly 4. Conversely, when it is necessary to release, the drive arm 55 is actuated to the second limiting piece 423, the drive arm 55 reversely drives the sleeve 54 and the drive disc 52 to rotate, the arc-shaped drive groove 521 drives the push rod 531 away from the axis, the clamping blocks 53 are separated, and the clamping on the positioning insertion rod 413 is cancelled.

[0072] The external rotation input of the driving arm 55 is transmitted to the driving disc 52 through the sleeve 54, the arc-shaped driving groove 521 converts the rotation motion into the radial thrust of the push rod 531, the cooperation of the guide groove 511 and the slider 532 ensures that the thrust acts on the clamping block 53 along the predetermined path, and the synchronous clamping of the three clamping blocks 53 on the positioning plug 413 is realized; the limiting effect of the first limiting part 422 and the second limiting part 423 maintains the stability of the driving arm 55 in the locked or released state, and avoids accidental operation. At the same time, the size design of the circular hole adapts to the motion deviation in the insertion process, and ensures the smoothness of the operation and the instantaneity of the locking.

[0073] The design of the locking assembly 5 significantly improves the fixing reliability of the clamping assembly 4 and the stability of the overall structure. Through the cooperative connection of the guide disc 51, the driving disc 52, the clamping block 53, the sleeve 54 and the driving arm 55, the locking assembly 5 can accurately lock the positioning plug 413, prevent it from being separated from the plug hole 421, and avoid the displacement of the clamping assembly 4 in the wearing or using process, thereby ensuring the electrical connection continuity of the induction wire group 2 and the monitoring sensor 3. The motion guiding mechanism of the arc-shaped driving groove 521 and the guide groove 511 improves the accuracy and response speed of the locking, and the multi-point clamping of the three clamping blocks 53 further enhances the anti-pulling ability, which is suitable for dynamic nursing scenes.

[0074] In the embodiment, the puncture part 414 is a conical structure, and the diameter of the side of the puncture part 414 close to the positioning plug 413 is greater than the diameter of the positioning plug 413, forming a limiting part cooperating with the clamping block 53.

[0075] When the three clamping blocks 53 clamp the positioning plug 413, the limiting part forms a clamping connection with the clamping block 53, and due to the action of the limiting part, the positioning plug 413 cannot be separated from the clamping of the three clamping blocks 53. Example two

[0076] As Figure 15 shown, the present application also provides a monitoring system, which comprises the above-mentioned intelligent paper diaper with monitoring function, a transmission module and a handheld terminal. The intelligent paper diaper is used for detecting the penetration of urine of a user and generating corresponding electrical signals. The transmission module is electrically connected with the monitoring sensor 3, and is used for wirelessly or wiredly transmitting the urine penetration information detected by the intelligent paper diaper to the handheld terminal. The handheld terminal is used for receiving the urine penetration data sent by the transmission module, and displaying, storing and prompting according to the received data.

[0077] In the implementation process, the intelligent diaper is worn on the user's body. When the user urinates, the urine is absorbed by the diaper body 1 and gradually spreads, sequentially contacting the first electrode lines 21 of different lengths, thereby forming a closed circuit between the first electrode lines 21 and the second electrode lines 22 through the conductivity of the urine, and the monitoring sensor 3 detects the corresponding electrical signal. The monitoring sensor 3 is built-in with a battery, and only generates current when the urine forms a conduction, thereby achieving energy saving. The detection signal is transmitted to the transmission module through the first conductor 231 and the second conductor 232, and the transmission module sends the signal to the handheld terminal in real time.

[0078] The handheld terminal determines the penetration degree of urine in the diaper according to the order and number of received electrical signals, and displays the determination result in a visual form. The handheld terminal can also trigger prompt information according to the set threshold value, including sound prompt or light prompt, thereby helping the nursing staff to replace the diaper or perform corresponding nursing in time. Through the system, the intelligent diaper, the transmission module and the handheld terminal form a coordinated cooperation, so that the urine penetration monitoring and user prompting are realized in real time, visualization and high efficiency, while ensuring that the entire system is in a low power consumption mode in a non-working state, prolonging the monitoring period and the service life of the equipment. Embodiment three

[0079] In the first step, the intelligent diaper with monitoring function is worn on the user's body, ensuring that the diaper body 1 is in good contact with the user's skin, so that the urine can be absorbed by the diaper body 1 in time after being discharged and spread to the area where the first electrode lines 21 are located.

[0080] In the second step, when the user urinates, the urine is absorbed by the diaper body 1 and gradually spreads, so that the first electrode lines 21 sequentially form a conductive path with the second electrode lines 22, and the monitoring sensor 3 detects and records the electrical signal changes generated by each first electrode line 21. The monitoring sensor 3 determines the penetration degree of urine in the diaper body 1 according to the order and number of electrical signals, and sends the detection information to the transmission module.

[0081] Furthermore, through the electrical signal communication of the first electrode lines 21 and the second electrode lines 22, the order of the urine in the diaper body 1 contacting the first electrode lines 21 of different lengths is sequentially detected; according to the sequential conduction of different first electrode lines 21, the urine penetration degree is divided into different levels; and after the monitoring sensor 3 detects the urine penetration forming a conduction signal, the response device 6 is triggered to perform sound prompt or light prompt, thereby realizing the graded monitoring and real-time prompting of the urine penetration process.

[0082] Thirdly, the transmission module transmits the urine penetration data collected by the monitoring sensor 3 to the handheld terminal, the handheld terminal receives and analyzes the data, judges the detection result according to the preset urine penetration level, and displays the penetration level information in a visual manner.

[0083] Fourthly, the handheld terminal judges whether to trigger a prompt according to the urine penetration level, and the response device 6 generates a sound prompt or a light prompt to remind the nursing staff to replace the paper diaper or take corresponding measures in time.

It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
