Description

Technical Field

[0001] This invention relates to the field of diaper technology, specifically to a smart diaper with monitoring functions, a monitoring system, and a method. Background Technology

[0002] Disposable diapers, widely used in hygiene products for infants, the elderly, and in special care settings, primarily function to absorb and lock in urine through internal absorbent materials, keeping the user's skin dry and providing a comfortable wearing experience. In recent years, with the development of smart technology, diapers with urine monitoring functions have gradually gained attention. These smart diapers typically integrate sensors or conductive materials into traditional diapers, detecting urine infiltration to determine if urination has occurred and transmitting relevant information to caregivers or monitors via electrical signals or wireless communication. Such products improve the timeliness of care to a certain extent, especially in infant care, elderly care, or medical rehabilitation, reducing the burden of care and improving the user's quality of life.

[0003] However, existing diapers with urine monitoring functions still have certain limitations in practical applications. Current monitoring technologies mainly focus on whether urine has seeped into the diaper, meaning they can only determine if urination has occurred, but cannot further distinguish the amount of urine or the diaper's absorbency. This single monitoring method is insufficient to meet actual care needs, as the amount of urine directly relates to whether the diaper needs to be changed immediately and whether there is a risk of leakage due to reaching its absorbency limit. Furthermore, existing technologies typically lack the ability to categorize urine volume, failing to provide caregivers with more precise reminders about when to change diapers, potentially leading to premature or delayed diaper changes, affecting user comfort or increasing care costs. Therefore, there is an urgent need for a smart diaper capable of categorizing urine volume monitoring to further optimize care efficiency and user experience. Summary of the Invention

Detailed Implementation

[0020] 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.

[0021] 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.

[0022] Example 1 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 of different lengths and one second electrode wire 22, the first electrode wire 21 and the second electrode wire 22 being connected to the monitoring sensor 3 respectively; 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 sequentially connects with the second electrode wire 22 through the urine according to the length difference. The monitoring sensor 3 monitors the change of electrical signal according to the order of connection to determine the degree of urine permeation in the diaper body 1.

[0023] 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.

[0024] In terms of its mechanism of action, urine acts as a conductive medium. When it permeates to the location of the first electrode line 21, it creates an electrical signal path between the first electrode line 21 and the second electrode line 22. The monitoring sensor 3 detects this signal and makes a judgment. As the amount of urine increases, more first electrode lines 21 of different lengths are sequentially activated, and the order in which each electrode line is activated causes a change in the electrical signal. The monitoring sensor 3 can determine the diffusion range and penetration degree of urine within the diaper body 1 by identifying the order and quantity of electrical signals, thereby achieving real-time monitoring of the urination process. Thus, the entire device achieves the coordination between the electrode line structure and the monitoring sensor 3 without affecting the normal use function of the diaper body 1, ensuring the sensitivity and reliability of the monitoring.

[0025] In this embodiment, there are three first electrode lines 21, each spaced apart from the second electrode line 22, and arranged sequentially along the longitudinal direction of the diaper body 1. Since the three first electrode lines 21 differ in length, a tiered distribution from top to bottom or from inside to outside can be formed inside the diaper body 1. As urine gradually diffuses from the discharge point outwards, it will inevitably contact different first electrode lines 21 sequentially according to the arrangement of the electrode lines, thus ensuring the stepwise nature of permeability monitoring in the structural layout.

[0026] In this embodiment, the three first electrode lines 21 correspond to the first, second, and third levels of urine permeation, respectively. Specifically, when urine first permeates to the longest first electrode line 21, this electrode line and the second electrode line 22 form a closed circuit through urine conductivity. The monitoring sensor 3 detects the appearance of an electrical signal and determines that this corresponds to the first level of permeation. As urine continues to increase and spread to the medium-length first electrode line 21, the second electrode line becomes conductive, and the monitoring sensor 3 detects a new change in electrical signal, determining that the permeation level has reached the second level. As urine further increases, the shortest first electrode line 21 is covered by urine and becomes conductive. The monitoring sensor 3 detects a change in electrical signal again, determining that the urine permeation level has reached the third level. Thus, by using the sequence of signals corresponding to the length differences of the three first electrode lines 21, accurate identification and determination of urine volume in stages can be achieved.

[0027] In this embodiment, the sensing wire group 2 further includes a connecting portion 23. The connecting portion 23 is located at the end region of the sensing wire group 2, connected to the first electrode line 21 and the second electrode line 22, and has a first conductor 231 and a second conductor 232 disposed on its surface. The first conductor 231 is connected to the first electrode line 21, and the second conductor 232 is connected to the second electrode line 22. The first conductor 231 and the second conductor 232 are respectively connected to the positive and negative terminals of the monitoring sensor 3. This connection method ensures a stable correspondence between the first electrode line 21 and the second electrode line 22 in the circuit. When urine acts as a conductive medium, creating a connection between them, current can be transmitted to the monitoring sensor 3 via the first conductor 231 and the second conductor 232, enabling the monitoring sensor 3 to instantly capture changes in the electrical signal. Since the first conductor 231 and the second conductor 232 respectively serve as the positive and negative terminals, their electrical connection is clear, avoiding interference or confusion during signal transmission and ensuring the stability and accuracy of the electrical signal during transmission. In this way, the electrode wire and the monitoring sensor 3 form a complete closed circuit system, providing a reliable electrical basis for the real-time determination of the degree of urine permeability.

[0028] In this embodiment, the smart diaper with monitoring function also includes a response device 6. The response device 6 is configured to trigger an audio or light response based on the urine penetration level monitored by the monitoring sensor 3. Specifically, when the monitoring sensor 3 detects an electrical signal generated between the first electrode line 21 and the second electrode line 22 due to urine conduction, the electrical signal is transmitted to the response device 6 for signal recognition and response control. When the penetration level reaches different levels, the response device 6 can output different forms of prompt information. For example, it can trigger an audio response during initial monitoring to alert caregivers that urination has occurred, and trigger a light response when the penetration level further increases, thereby indicating in a more intuitive way that the diaper needs to be changed promptly.

[0029] In this embodiment, the second electrode line 22 is S-shaped. By designing the second electrode line 22 in an S-shape, it can form a larger coverage area inside the diaper body 1, allowing the first electrode line 21 to maintain a distance from the second electrode line 22 at multiple positions when distributed longitudinally. Thus, as urine gradually diffuses and permeates, any one of the first electrode lines 21 can connect with the second electrode line 22 at the corresponding position through urine conductivity, thereby improving the sensitivity and reliability of monitoring. The S-shaped arrangement not only increases the contact probability between the second electrode line 22 and the first electrode line 21, but also extends the conductive path within a limited space, ensuring the stability of electrical signal transmission during monitoring and further improving the accuracy of urine permeation monitoring.

[0030] This smart diaper with monitoring capabilities can also provide corresponding prompts based on different urine volumes, effectively guiding caregivers or users to change the diaper in a timely manner. Compared to traditional diapers, the smart diaper of this invention significantly improves the real-time performance and accuracy of urine monitoring by integrating the induction wire group 2 and the monitoring sensor 3. Furthermore, the detachable monitoring sensor 3 further enhances the system's economy and sustainability, making it suitable for infants, the elderly, or individuals requiring special care.

[0031] In this embodiment, the monitoring sensor 3 has a built-in battery to provide power for the entire monitoring and response process. Due to the structural design of the first electrode line 21 and the second electrode line 22, when no urine is present, the first electrode line 21 and the second electrode line 22 are always in an open circuit state, and the monitoring sensor 3 will not receive an electrical signal input, thus avoiding invalid circuit conduction. This design allows the monitoring sensor 3 to operate in a low-power standby mode when not in use, triggering current transmission and generating a monitoring signal only when urine permeates and forms a conductive path. This significantly reduces battery power consumption and extends the overall lifespan and battery life of the device. This open-circuit-conduction working mode ensures both the real-time nature of urine permeation monitoring and the high efficiency of power management.

[0032] Furthermore, the monitoring sensor 3 is an existing miniature electrical signal sensor based on conductivity monitoring. Specifically, it can be a commercially available low-power conductivity sensor (such as a microelectrode sensor or electrochemical sensor based on conductivity measurement). This type of sensor typically includes a microprocessor, signal amplification circuit, and electrical signal monitoring module, enabling highly sensitive capture and processing of weak electrical signals. The monitoring sensor 3 forms a stable electrical connection with the sensing wire group 2 in the diaper body 1 through conductive fasteners or plug-in terminals. Its compact size makes it suitable for detachable installation on the outside or edge area of ​​the diaper body 1, ensuring portability and reusability during use.

[0033] In this embodiment, the diaper body 1 is provided with a first fixing part 11 and a second fixing part 12, located on the two side edge areas of the diaper body 1, respectively, for fixing the diaper to the user's waist and leg areas during wear. The first fixing part 11 is provided with a nylon fleece surface 13, which has a soft fleece structure and can form a firm adhesion with the nylon hook surface 15 on the fixing strap 14. The second fixing part 12 is connected to the fixing strap 14, which is made of a flexible material and has a nylon hook surface 15 at its end. The hook-shaped structure of the nylon hook surface 15 can fit tightly with the nylon fleece surface 13 to form a reliable fixed connection. This fixing method, through the adhesion mechanism between the nylon hook surface 15 and the nylon fleece surface 13, ensures that the diaper body 1 can fit closely to the user's body contour during wear, preventing slippage or displacement.

[0034] During the wearing process, the diaper body 1 passes under the user's crotch. Then, by bending the diaper body 1, the first fixing part 11 and the second fixing part 12 are brought closer together or in contact. The operator then aligns the nylon hook surface 15 on the fixing strap 14 with the nylon fleece surface 13 on the first fixing part 11, thus securing the diaper body 1. At this point, the first fixing part 11, the second fixing part 12, and the diaper body 1 together form a space for the user's legs to pass through, ensuring the diaper fits the body snugly after wearing while providing sufficient flexibility for leg movement. This fixing structure design is not only easy to operate but also adaptable to users of different body types. By adjusting the alignment of the nylon hook surface 15 and the nylon fleece surface 13, a personalized fit can be achieved, thereby improving wearing comfort and stability.

[0035] The internal structure of the diaper body 1 is composed of multiple layers of composite materials, including non-woven fabric 16, absorbent layer 17, and sealing layer 18, each performing different functions to achieve effective urine absorption and monitoring. The non-woven fabric 16, as the inner layer in direct contact with the user's skin, is made of soft, breathable, and skin-friendly non-woven material, ensuring comfort and breathability while allowing urine to quickly permeate to the absorbent layer 17 below. The absorbent layer 17, located between the non-woven fabric 16 and the sealing layer 18, is composed of superabsorbent polymer (SAP) and other absorbent materials, possessing strong absorbency and water-locking capabilities. It can quickly absorb and lock in urine, preventing leakage. The sealing layer 18, as the outermost layer of the diaper, is made of waterproof and breathable material, effectively preventing urine from seeping out of the absorbent layer 17 while maintaining a certain degree of breathability to enhance user comfort. The first electrode wire 21 and the second electrode wire 22 are both laid between the non-woven fabric 16 and the absorbent layer 17, close to the area of ​​the absorbent 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.

[0036] In practical use, when urine is produced, it first quickly seeps into the absorbent layer 17 through the water permeability of the non-woven fabric 16. The absorbent layer 17 rapidly absorbs and locks in the urine using its superabsorbent polymer material, preventing urine from spreading inside the diaper or leaking out. The first electrode line 21 and the second electrode line 22, located between the non-woven fabric 16 and the absorbent layer 17, can promptly contact the seeped urine, forming a closed circuit using the conductivity of the urine, generating an electrical signal and transmitting it to the monitoring sensor 3.

[0037] In this embodiment, the smart diaper with monitoring function further includes a clamping component 4, which is used to clamp the monitoring sensor 3 onto the diaper body 1. By setting the clamping component 4, the monitoring sensor 3 can be stably fixed on the diaper body 1, avoiding sensor position displacement due to bending or movement of the diaper body 1 during use. The clamping effect of the clamping component 4 on the monitoring sensor 3 ensures reliable electrical connection between the sensor and the first electrode line 21 and the second electrode line 22, thereby ensuring that the transmission of electrical signals is not affected by external interference.

[0038] In this embodiment, the clamping assembly 4 includes a first clamping part 41, a second clamping part 42, a rotating shaft 43, and a torsion spring 44. The first clamping part 41 and the second clamping part 42 are connected to each other by the rotating shaft 43, which passes through the center of both parts to form a rotation axis, allowing the first clamping part 41 and the second clamping part 42 to rotate relative to each other around the rotating shaft 43. The torsion spring 44 is sleeved on the rotating shaft 43, with its two ends connected to the first clamping part 41 and the second clamping part 42 respectively. The elastic restoring force of the torsion spring 44 provides a continuous torsional force to the two clamping parts, causing the first clamping part 41 and the second clamping part 42 to tend to be closed when no external force is applied, thereby firmly clamping them to a predetermined position on the diaper body 1.

[0039] The clamping surfaces of the first clamping part 41 and the second clamping part 42 are designed to fit the outer surface of the diaper body 1. In this embodiment, they are smooth contact surfaces to avoid damage to the diaper body 1 or affecting wearing comfort. The rotating shaft 43, as the core connecting component of the clamping assembly 4, not only provides the rotational 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 torsion spring 44 allows the clamping assembly 4 to automatically return to the clamped state during the clamping process.

[0040] During use, the operator presses the first clamping part 41 and the second clamping part 42 away from the diaper body 1, causing the two clamping parts to rotate relative to each other around the pivot 43, overcoming the elastic force of the torsion spring 44, resulting in the compression of the torsion spring 44. At this time, the first clamping part 41 and the second clamping part 42 open on the side closer to the diaper body 1, forming a clamping space sufficient to accommodate the edge of the diaper body 1 or a predetermined clamping area. After placing the diaper body 1 in this clamping space, the operator releases the pressure on the first clamping part 41 and the second clamping part 42, and the elastic restoring force of the torsion spring 44 drives the two clamping parts to return to the closed state, thereby firmly clamping the diaper body 1. The clamping assembly 4 is usually fixed on the diaper body 1 near the mounting position of the monitoring sensor 3 to ensure that the electrical connection point between the sensor and the sensing wire assembly 2 does not loosen due to movement or pulling during the wearing process.

[0041] Through the coordinated operation of the first clamping part 41, the second clamping part 42, the rotating shaft 43 and the torsion spring 44, the clamping assembly 4 achieves a stable fixation of the diaper body 1, ensuring the positional stability of the monitoring sensor 3 during wearing and use, thereby guaranteeing the continuity and accuracy of urine monitoring.

[0042] The first clamping part 41 is provided with a sliding groove 411, which provides a sliding path for the first conductor 231 and the second conductor 232, so that the connecting part 23 can be accurately inserted into the predetermined position. A limiting slot 412 is further provided in the sliding groove 411 to limit and fix the first conductor 231 and the second conductor 232 when they slide to the correct position, thereby ensuring the reliability and stability of the electrical connection.

[0043] A receiving space is formed between the first clamping part 41 and the second clamping part 42 to accommodate the clamping area of ​​the connecting part 23 and the diaper body 1. During use, the operator presses the side of the first clamping part 41 and the second clamping part 42 away from the diaper body 1, causing the two clamping parts to rotate relative to each other around the pivot 43, opening the clamping space. Then, the first conductor 231 and the second conductor 232 of the connecting part 23 are inserted along the slide groove 411 on the first clamping part 41. The first conductor 231 and the second conductor 232 slide within the slide groove 411 until they reach the position of the limiting slot 412. At this point, the pressing of the first clamping part 41 and the second clamping part 42 is released, and the elastic restoring force of the torsion spring 44 drives the two clamping parts to close, causing the first clamping part 41 and the second clamping part 42 to apply clamping force to the corresponding areas of the connecting part 23 and the diaper body 1, thereby firmly fixing the connecting part 23 within 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 to ensure that the first conductor 231 and the second conductor 232 can be firmly locked after insertion, avoiding loosening due to vibration or movement.

[0044] The limiting slot 412 contains two guide cores, corresponding to the positive and negative terminals of the monitoring sensor 3, respectively. These two guide cores serve as the medium for transmitting electrical signals, directly contacting the first conductor 231 and the second conductor 232 to form a stable electrical connection path. The guide cores are further connected to the monitoring sensor 3 and a battery (not shown in the figure) via internal wiring, providing power to the monitoring sensor 3 and transmitting the urine monitoring signal generated by the sensing wire group 2 to the monitoring sensor 3 for processing. The limiting design of the limiting slot 412 not only ensures precise alignment between the first conductor 231 and the second conductor 232 and the guide cores but also prevents the first conductor 231 and the second conductor 232 from sliding or disengaging during clamping through its snap-fit ​​structure, thereby avoiding signal interruption or unstable transmission. The coordinated design of the sliding groove 411 and the limiting slot 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.

[0045] The slide groove 411 guides the first conductor 231 and the second conductor 232, ensuring they slide smoothly and accurately into the limiting slot 412. The limiting slot 412, through its geometry and the design of the guide core, achieves physical fixation of the first conductor 231 and the second conductor 232 and stable transmission of electrical signals. When urine triggers the first electrode line 21, the generated electrical signal is transmitted through the first conductor 231 and the second conductor 232 of the connecting part 23 to the guide core, and then from the guide core to the monitoring sensor 3 for analysis and processing. The limiting function of the limiting slot 412 effectively prevents the first conductor 231 and the second conductor 232 from detaching from the guide core due to external forces (such as the wearer's movement or the deformation of the diaper), ensuring the continuity of electrical signal transmission and the accuracy of the monitoring results.

[0046] In this embodiment, the first clamping part 41 is provided with two positioning rods 413. The positioning rods 413 are fixedly disposed on the clamping surface of the first clamping part 41 facing the second clamping part 42 and have a columnar structure. A piercing part 414 is provided at the end of the positioning rod 413 away from the first clamping part 41. The tip shape of the piercing part 414 facilitates piercing the material layer of the diaper body 1 during clamping, while ensuring that the absorbency or overall structure of the diaper body 1 is not significantly damaged. This achieves precise positioning and secure fixation of the clamping component 4 on the diaper body 1.

[0047] In the connection structure of the clamping assembly 4, the positioning insert 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 insert 413 is inserted into the receiving structure of the second clamping part 42 along its axial direction, while the piercing part 414 passes through a predetermined area of ​​the diaper body 1, usually a non-absorbent functional area near the edge, to avoid affecting the performance of the absorbent layer 17. The tip design of the piercing part 414 ensures that it can smoothly penetrate the multi-layer composite structure of the diaper body 1 (such as the non-woven fabric 16 and the encapsulation layer 18) and form a stable anchoring point after being inserted into the second clamping part 42. The length and distribution of the positioning insert 413 are precisely designed to ensure that the first clamping part 41 and the second clamping part 42 can apply force evenly during the clamping process, and at the same time, the synergistic effect of the two positioning inserts 413 enhances the anti-displacement ability of the clamping assembly 4 on the diaper body 1.

[0048] In this embodiment, the second clamping part 42 is provided with an insertion hole 421 for accommodating the positioning rod 413. A locking component 5 is provided in the insertion hole 421 to reliably lock the inserted positioning rod 413 and prevent it from accidentally coming out of the insertion hole 421, thereby ensuring that the clamping component 4 and the diaper body 1 are firmly connected. The locking assembly 5 includes a guide plate 51, two drive plates 52, three clamping blocks 53, a sleeve 54, and a drive arm 55. The guide plate 51 is fixedly installed inside the socket 421, providing guidance and support. The two drive plates 52 are fixedly installed on the inner wall of the sleeve 54, which is rotatably installed inside the socket 421. The end of the sleeve 54 away from the positioning rod 413 passes through the socket 421 and is fixedly connected to the drive arm 55. The second clamping part 42 is provided with a first limiting member 422 and a second limiting member 423 to limit the rotation range of the drive arm 55. The clamping block 53 is located between the two drive plates 52. Each clamping block 53 is provided with a lever 531. The lever 531 passes through the arc-shaped drive groove 521 on the drive plate 52, and a slider 532 is fixedly connected to its end near the guide plate 51. The slider 532 extends into the guide groove 511 on the guide plate 51 and slides therewith.

[0049] The guide plate 51 serves as a fixed reference, providing a radial sliding path for the slider 532 via 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 plate 52 forms a sliding engagement with the lever 531. When the drive plate 52 rotates, the curved shape of the arc-shaped drive groove 521 can convert the rotational motion into the radial displacement of the lever 531. The sleeve 54 serves as the transmission core, converting the external operation of the drive arm 55 into the synchronous rotation of the drive plate 52. The fixed connection between the drive arm 55 and the sleeve 54 ensures reliable torque transmission, while the first limiting member 422 and the second limiting member 423 define the open and closed states of the locking assembly 5 by locking the position of the drive arm 55. The clamping block 53 is connected to the drive plate 52 and the guide plate 51 via the lever 531 and the slider 532, achieving stable positioning between the two drive plates 52. At the same time, the even distribution of the three clamping blocks 53 ensures multi-point clamping of the positioning rod 413, improving the uniformity and reliability of locking.

[0050] During use, when the first clamping part 41 and the second clamping part 42 close under the action of the torsion spring 44 to clamp the diaper body 1, the positioning rod 413 passes through the round holes on the guide plate 51 and the drive plate 52. The diameter of these round holes is designed to be larger than the diameter of the positioning rod 413 to accommodate the non-axial insertion movement of the positioning rod 413 and ensure smooth insertion. Subsequently, the operator moves the drive arm 55 to rotate it until it is locked within the first limiting member 422. At this time, the drive arm 55 drives the sleeve 54 to rotate, and 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 lever 531 to move along the guide direction of the guide groove 511, so that the lever 531 is close to the axis of the drive disc 52. The sliding connection of the slider 532 in the guide groove 511 prevents the rotation of the lever 531, ensuring linear stability of the movement. The displacement of the lever 531 causes the three clamping blocks 53 to move closer to each other, applying clamping force to the positioning insert 413 to achieve locking. Since the positioning insert 413 directly passes through the diaper body 1, this locking connection further prevents the displacement of the clamping assembly 4 relative to the diaper body 1, thereby maintaining a stable connection between the connecting part 23 and the clamping assembly 4. Conversely, when release is required, the drive arm 55 is moved into the second limit member 423. The drive arm 55 reverses and drives the sleeve 54 and drive disk 52 to rotate. The arc-shaped drive groove 521 drives the lever 531 away from the axis, the clamping block 53 separates, and the clamping of the positioning rod 413 is released.

[0051] The external rotational input of the drive arm 55 is transmitted to the drive disk 52 through the sleeve 54. The arc-shaped drive groove 521 converts the rotational motion into the radial thrust of the lever 531. The cooperation of the guide groove 511 and the slider 532 ensures that the thrust acts on the clamping block 53 along a predetermined path, realizing the synchronous clamping of the positioning rod 413 by the three clamping blocks 53. The limiting function of the first limiting member 422 and the second limiting member 423 maintains the stability of the drive arm 55 in the locked or released state, avoiding accidental operation. At the same time, the size design of the circular hole adapts to the movement deviation during the insertion process, ensuring the smoothness of operation and the immediacy of locking.

[0052] The locking component 5 significantly improves the fixation reliability and overall structural stability of the clamping component 4. Through the coordinated connection of the guide plate 51, drive plate 52, clamping block 53, sleeve 54, and drive arm 55, the locking component 5 precisely locks the positioning rod 413, preventing it from disengaging from the insertion hole 421. This avoids displacement of the clamping component 4 during wear or use, ensuring the continuity of the electrical connection between the sensing wire group 2 and the monitoring sensor 3. The motion guidance mechanism of the arc-shaped drive groove 521 and guide groove 511 improves the locking accuracy and response speed, while the multi-point clamping of the three clamping blocks 53 further enhances the pull-out resistance, making it suitable for dynamic care scenarios.

[0053] In this embodiment, the puncture part 414 has a conical structure, and the diameter of the side of the puncture part 414 near the positioning rod 413 is larger than the diameter of the positioning rod 413, forming a limiting part that cooperates with the clamping block 53.

[0054] When the three clamping blocks 53 clamp the positioning rod 413, the limiting part and the clamping block 53 form a locking connection. Due to the action of the limiting part, the positioning rod 413 will not be able to get out of the clamping of the three clamping blocks 53.

[0055] Example 2 like Figure 15 As shown, the present invention also provides a monitoring system, which includes the aforementioned smart diaper with monitoring function, a transmission module, and a handheld terminal. The smart diaper monitors the permeation of user urine and generates corresponding electrical signals. The transmission module is electrically connected to the monitoring sensor 3 and is used to wirelessly or wiredly transmit the urine permeation information monitored by the smart diaper to the handheld terminal. The handheld terminal receives the urine permeation data sent by the transmission module and displays, stores, and provides prompts based on the received data.

[0056] In practical implementation, the smart diaper is worn by the user. When the user urinates, the urine is absorbed by the diaper body 1 and gradually diffuses, coming into contact with the first electrode wires 21 of different lengths in sequence. This forms a closed circuit between the first electrode wire 21 and the second electrode wire 22 due to the conductivity of the urine, and the monitoring sensor 3 detects the corresponding electrical signal. The monitoring sensor 3 has a built-in battery that only generates current when it detects urine conduction, thus achieving energy saving. The monitoring signal is transmitted to the transmission module via the first conductor 231 and the second conductor 232, and the transmission module sends the signal to the handheld terminal in real time.

[0057] The handheld terminal determines the degree of urine penetration in the diaper based on the sequence and quantity of received electrical signals, and displays the results visually. The handheld terminal can also trigger prompts, including audible or visual alerts, for different penetration levels based on set thresholds, helping caregivers change diapers or provide appropriate care in a timely manner. Through this system, the smart diaper, transmission module, and handheld terminal work together to achieve real-time, visual, and efficient urine penetration monitoring and user prompts, while ensuring the entire system operates in a low-power mode when not in use, extending the monitoring cycle and equipment lifespan.

[0058] Example 3 The first step is to put the smart diaper with monitoring function on the user to ensure good contact between the diaper body 1 and the user's skin, so that the urine can be absorbed by the diaper body 1 in time and diffused to the area where the first electrode line 21 is located after it is excreted.

[0059] In the second step, when the user urinates, the urine is absorbed by the diaper body 1 and gradually diffuses, causing the first electrode wire 21 to sequentially connect with the second electrode wire 22 through the urine to form a conductive path. The monitoring sensor 3 monitors and records the changes in electrical signals generated by each of the first electrode wires 21. The monitoring sensor 3 determines the degree of urine penetration inside the diaper body 1 based on the order and quantity of the electrical signals and sends the monitoring information to the transmission module.

[0060] Furthermore, by connecting the first electrode line 21 and the second electrode line 22 with electrical signals, the sequence of contact between urine inside the diaper body 1 and the first electrode lines 21 of different lengths is monitored. Based on the sequential conduction of different first electrode lines 21, the degree of urine penetration is divided into different levels. After the monitoring sensor 3 detects that urine penetration has formed a conduction signal, the response device 6 is triggered to provide an audible or visual alert, thereby achieving graded monitoring and real-time alerts of the urine penetration process.

[0061] Third, the transmission module transmits the urine permeability data collected by the monitoring sensor 3 to the handheld terminal. The handheld terminal receives and analyzes the data, judges the monitoring results according to the preset urine permeability level, and displays the permeability level information in a visual manner.

[0062] Fourth, the handheld terminal determines whether to trigger a prompt based on the urine permeability level, and triggers the response device 6 to generate an audible or visual prompt to remind caregivers to change the diaper or take appropriate action in a timely manner.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
