[0037] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0038] Please refer to Figures 1 to 4 This utility model provides a connector 10 for connecting an absorbent pad 20 and an absorbent pad monitor 30. The connector 10 includes a housing assembly 11 and a circuit assembly 12. The housing assembly 11 includes a first housing 111 and a second housing 112. The circuit assembly 12 includes a plug 121 and a conductive fiber 122. The plug 121 is inserted into the first housing 111. One end of the conductive fiber 122 is connected to the plug 121. The second housing 112 is connected to the first housing 111 and presses the plug 121 and the conductive fiber 122 together. The conductive fiber 122 is disposed inside the absorbent pad 20 and is used to conduct electricity when in contact with liquid.

[0039] Optionally, the conductive fiber 122 and the connector 121 can be connected by means of crimping, conductive adhesive, welding, etc., so that the conductive fiber 122 and the connector 121 are conductive. The portion of the conductive fiber 122 disposed inside the absorbent pad 20 can be connected and fixed to the absorbent pad 20 by means of weaving, bonding, crimping, etc., to prevent the conductive fiber 122 from falling out of the absorbent pad 20.

[0040] In some embodiments, the outer shell assembly 11 is connected and fixed to the absorbent pad 20. Optionally, one of the first outer shell 111 or the second outer shell 112 is connected and fixed to the absorbent pad 20, specifically by means of snap-fit, adhesive, riveting, etc., without limitation. Optionally, both the first outer shell 111 and the second outer shell 112 are connected and fixed to the absorbent pad 20. For example, a portion of the absorbent pad 20 is disposed between the first outer shell 111 and the second outer shell 112, and the first outer shell 111 and the second outer shell 112 together press the absorbent pad 20. By setting the outer shell assembly 11 to be connected and fixed to the absorbent pad 20, the connector 10 can be connected to the absorbent pad 20, making it convenient to carry and use.

[0041] In some embodiments, the first outer shell 111 and the second outer shell 112 are detachably connected. Specifically, the first outer shell 111 includes a base 1111 and a plurality of first fixing parts 1112, and the second outer shell 112 includes a shell body 1121 and a plurality of second fixing parts 1122. The plurality of first fixing parts 1112 are disposed on the base 1111, and the plurality of second fixing parts 1122 are disposed on the shell body 1121 and are connected one-to-one with the plurality of first fixing parts 1112, so that the first outer shell 111 and the second outer shell 112 are connected and fixed. The connector 121 is inserted into the base 1111. Optionally, the first fixing parts 1112 and the second fixing parts 1122 can be connected and fixed by means of snap-fit, screw-fit, riveting, etc., without limitation. By setting the first housing 111 and the second housing 112 to be detachably connected, the first housing 111 and the second housing 112 can be manufactured and processed separately, and the second housing 112 can be installed after the circuit assembly 12 is assembled. This reduces the production difficulty and assembly difficulty of the connector 10, and at the same time facilitates the maintenance and replacement of the circuit assembly 12.

[0042] The connector 10 provided by this utility model for connecting the absorbent pad 20 and the absorbent pad monitor 30, by setting up a housing assembly 11 and a circuit assembly 12, the housing assembly 11 includes a first housing 111 and a second housing 112, the circuit assembly 12 includes a plug 121 and a conductive fiber 122, the plug 121 is inserted into the first housing 111, one end of the conductive fiber 122 is connected to the plug 121, the second housing 112 is connected to the first housing 111 and presses the plug 121 and the conductive fiber 122 together, the conductive fiber 122 is used to be placed inside the absorbent pad 20 and is used to conduct when in contact with liquid, so that the connection between the plug 121 and the conductive fiber 122 is tight and not easy to break, thus ensuring the stability and accuracy of signal transmission between the absorbent pad monitor 30 and the absorbent pad 20.

[0043] In one implementation method, please refer to Figures 1 to 4The connector 121 includes a circuit board 1211 and a connector terminal 1212. The connector terminal 1212 is connected to the circuit board 1211. One end of the conductive fiber 122 is connected to the circuit board 1211. The connector terminal 1212 and the conductive fiber 122 extend from opposite ends of the circuit board 1211 in the first direction Y. The connector terminal 1212 is used to connect to the absorption pad monitor 30. The first housing 111 has a first space 1113 and a second space 1114. The first space 1113 and the second space 1114 are connected in the first direction Y. The connector terminal 1212 is inserted into the first space 1113. The circuit board 1211 is housed in the second space 1114. The second space 1114 is exposed to the outside in the second direction Z. The second housing 112 extends into the second space 1114 and presses the circuit board 1211 and the conductive fiber 122 together. The second direction Z intersects the first direction Y.

[0044] The plug-in terminal 1212 extends beyond the circuit board 1211 in the first direction Y and also extends into the first space 1113 in the first direction Y. It is used to connect to the absorbent pad monitor 30 to transmit the electrical signal on the conductive fiber 122 to the absorbent pad monitor 30. The absorbent pad monitor 30 can determine whether the object in the absorbent pad 20 is urine or feces based on the received electrical signal. Furthermore, the absorbent pad monitor 30 can also distinguish between normal urine and abnormal urine, as well as normal feces and abnormal feces based on the electrical signal, so that caregivers and wearers can be informed of the urination and defecation situation in real time and take timely action based on the results.

[0045] Optionally, the plug-in terminal 1212 and the circuit board 1211 can be connected via through-hole 1117 soldering, surface mounting, or crimping, so that the plug-in terminal 1212 and the solder points or contacts on the circuit board 1211 are correspondingly connected for signal transmission. Optionally, the portion of the plug-in terminal 1212 housed in the first space 1113 abuts against the inner wall of the first space 1113 to improve the connection stability between the plug-in terminal 1212 and the first housing 111. Optionally, the circuit board 1211 abuts against the inner wall of the second space 1114 to improve the connection stability between the circuit board 1211 and the first housing 111.

[0046] In a specific embodiment, the first outer shell 111 has a groove 1115 on its outer surface in the second direction Z. The groove 1115 connects the second space 1114 and the outside in the second direction Z. One end of the conductive fiber 122 is exposed in the groove 1115. The second outer shell 112 includes a shell body 1121 and a first protrusion 1123. The first protrusion 1123 is disposed on the shell body 1121 and the shell body 1121 is connected to the first outer shell 111. The first protrusion 1123 extends into the groove 1115 and presses the circuit board 1211 and the conductive fiber 122.

[0047] The groove 1115 penetrates one end face of the first housing 111 in the first direction Y, forming an outlet 1116. One end of the conductive fiber 122 is housed in the first space 1113 or the groove 1115 and extends out of the housing assembly from the outlet 1116 to enter the interior of the absorbent pad 20. The bottom wall of the outlet 1116 and the bottom wall of the first space 1113 are spaced apart in the second direction Z. That is, the first space 1113 has a sidewall on the side away from the second space 1114 in the first direction Y. The circuit board 1211 abuts against this sidewall to limit the circuit board 1211 in the first direction Y. The circuit assembly 12 also includes a copper pad 1223, which is connected to the circuit board 1211. One end of the conductive fiber 122 is connected to the surface of the copper pad 1223 facing away from the circuit board 1211 and protrudes out of the first space 1113 and is located in the groove 1115.

[0048] The distance between the two opposite sidewalls of the groove 1115 in the third direction X gradually increases along the second direction Z. That is, the opening of the groove 1115 toward the second housing 112 in the second direction Z is flared. The shape of the first protrusion 1123 is adapted to the shape of the groove 1115 so as to guide the first housing 111 and the second housing 112 during assembly and reduce the positioning difficulty of assembly.

[0049] The first outer shell 111 has a groove 1115 on its outer surface in the second direction Z. The groove 1115 connects the second space 1114 and the outside in the second direction Z. One end of the conductive fiber 122 is exposed in the groove 1115. The second outer shell 112 includes a shell body 1121 and a first protrusion 1123. The first protrusion 1123 is disposed on the shell body 1121 and the shell body 1121 is connected to the first outer shell 111. The first protrusion 1123 extends into the groove 1115 and presses the circuit board 1211 and the conductive fiber 122, so that the second outer shell 112 can extend into the first outer shell 111 and press the circuit board 1211 and the conductive fiber 122. This provides a constant and uniform mechanical pressure at the connection point of the circuit board 1211 and the conductive fiber 122, and at the same time improves the connection stability of the first outer shell 111 and the second outer shell 112.

[0050] In a specific embodiment, there are multiple conductive fibers 122, grooves 1115, and first protrusions 1123. The multiple grooves 1115 are spaced apart in the third direction X. The multiple conductive fibers 122 are arranged in a one-to-one correspondence with the multiple grooves 1115. The multiple first protrusions 1123 are arranged in a one-to-one correspondence with the multiple grooves 1115. The multiple conductive fibers 122 are used to conduct when in contact with liquid. The first direction Y, the second direction Z, and the third direction X intersect each other.

[0051] In a specific embodiment, the conductive fiber 122 includes a first conductive fiber 1221 and a second conductive fiber 1222. There are two grooves 1115 and two first protrusions 1123. The first conductive fiber 1221 and the second conductive fiber 1222 are respectively disposed in two grooves 1115. The two first protrusions 1123 each extend into their respective grooves 1115 and press against the first conductive fiber 1221 and the second conductive fiber 1222 on the circuit board 1211. The aforementioned absorbent pad monitor 30 outputs a first electrical signal to the first conductive fiber 1221. When the first conductive fiber 1221 and the second conductive fiber 1222 come into contact with liquid, they become conductive. The first electrical signal is converted into a second electrical signal by the liquid and transmitted to the second conductive fiber 1222. The absorbent pad monitor 30 receives and processes the second electrical signal to detect the liquid within the absorbent pad 20.

[0052] By setting multiple conductive fibers 122, grooves 1115, and first protrusions 1123, with multiple grooves 1115 spaced apart in the third direction X, multiple conductive fibers 122 corresponding to multiple grooves 1115, and multiple first protrusions 1123 corresponding to multiple grooves 1115, the multiple conductive fibers 122 are used to conduct when in contact with liquid, which improves the performance of the absorbent pad monitor 30 in detecting the liquid condition inside the absorbent pad 20. At the same time, the multiple conductive fibers 122 are tightly connected to the circuit board 1211 under the pressure of the multiple first protrusions 1123, making it less prone to breakage and ensuring the stability and accuracy of signal transmission between the absorbent pad monitor 30 and the absorbent pad 20.

[0053] In a specific embodiment, the first outer shell 111 is further provided with a through hole 1117, which connects the second space 1114 and the outside in the second direction Z. The through hole 1117 and the groove 1115 are spaced apart in the first direction Y. The circuit board 1211 is exposed through the through hole 1117. The second outer shell 112 also includes a second protrusion 1124, which is disposed on the shell body 1121. The second protrusion 1124 and the first protrusion 1123 are spaced apart in the first direction Y. The second protrusion 1124 extends into the through hole 1117 and presses the circuit board 1211 and the first outer shell 111 together.

[0054] Optionally, the second housing 112 further includes an extension 1125, one end of which is connected to one end of the housing body 1121 in the first direction Y, and the other end is connected to the second protrusion 1124. The second protrusion 1124 protrudes from the extension 1125 in the second direction Z. The first housing 111 also has a notch 1118 for receiving the extension 1125. When the first housing 111 and the second housing 112 are connected and fixed, the extension 1125 is received in the notch 1118. The second protrusion 1124 passes through a through hole 1117. This arrangement improves the connection strength between the second protrusion 1124 and the housing body 1121, which is beneficial for pressing the circuit board 1211 onto the first housing 111.

[0055] The first outer shell 111 is also provided with a through hole 1117, which connects the second space 1114 and the outside in the second direction Z. The through hole 1117 and the groove 1115 are spaced apart in the first direction Y. The circuit board 1211 is exposed in the through hole 1117. The second outer shell 112 also includes a second protrusion 1124, which is disposed on the shell body 1121. The second protrusion 1124 and the first protrusion 1123 are spaced apart in the first direction Y. The second protrusion 1124 extends into the through hole 1117 and presses the circuit board 1211 and the first outer shell 111 together, so that the connection between the circuit board 1211 and the first outer shell 111 is tighter, preventing the circuit board 1211 from falling out of the first outer shell 111 and damaging the circuit structure.

[0056] In another implementation method, please refer to Figures 5 to 7 The connector 121 includes a circuit board 1211 and a connector terminal 1212. The connector terminal 1212 is connected to the circuit board 1211. One end of the conductive fiber 122 is connected to the circuit board 1211. The connector terminal 1212 and the conductive fiber 122 extend from opposite ends of the circuit board 1211 in the first direction Y. The connector terminal 1212 is used to connect to the absorption pad monitor 30. The first housing 111 and the second housing 112 are respectively disposed on opposite sides of the connector 121 in the second direction Z and enclose a receiving space 113. The connector terminal 1212 is inserted into the receiving space 113. The circuit board 1211 is received in the receiving space 113. The first housing 111 and the second housing 112 press the circuit board 1211 and the conductive fiber 122 together. The second direction Z intersects the first direction Y.

[0057] In a specific embodiment, a first abutting portion 1119 is provided on the surface of the first outer shell 111 facing the second outer shell 112, and a second abutting portion 1126 is provided on the surface of the second outer shell 112 facing the first outer shell 111. The first abutting portion 1119 and the second abutting portion 1126 are arranged opposite to each other in the second direction Z and are respectively located on both sides of the conductive fiber 122 in the second direction Z. The first abutting portion 1119 abuts against the side of the conductive fiber 122 facing away from the circuit board 1211, and the second abutting portion 1126 abuts against the surface of the circuit board 1211 facing away from the conductive fiber 122, so as to press the circuit board 1211 and the conductive fiber 122 together.

[0058] In a specific embodiment, there are multiple conductive fibers 122, first abutting portions 1119 and second abutting portions 1126. The multiple conductive fibers 122 are spaced apart in the third direction X. The multiple first abutting portions 1119 and the multiple second abutting portions 1126 are respectively arranged in a one-to-one correspondence with the multiple conductive fibers 122. The multiple conductive fibers 122 are used to conduct electricity when in contact with liquid. The first direction Y, the second direction Z and the third direction X intersect each other.

[0059] In a specific embodiment, the conductive fiber 122 includes a first conductive fiber 1221 and a second conductive fiber 1222. There are at least two first abutting portions 1119 and second abutting portions 1126. The first conductive fiber 1221 and the second conductive fiber 1222 are respectively connected to two opposite surfaces of the circuit board 1211 in the second direction Z by conductive adhesive, and the first conductive fiber 1221 and the second conductive fiber 1222 are spaced apart in the third direction X.

[0060] In a specific embodiment, the circuit assembly 12 further includes a copper pad 1223 and conductive adhesive 1224. The copper pad 1223 is connected to the circuit board 1211. One end of the conductive fiber 122 is bonded to the copper pad 1223 by the conductive adhesive 1224, so that there is a reliable electrical connection between the conductive fiber 122 and the copper pad 1223. The conductive adhesive 1224 has a certain degree of flexibility and elasticity, which reduces the risk of the conductive fiber 122 falling off under external force. At the same time, it avoids the high temperature damage to the conductive fiber 122 and the circuit board 1211 caused by traditional soldering. It also facilitates the fixing of the conductive fiber 122 by processes such as dispensing, screen printing, and spraying according to the shape of the conductive fiber 122, thereby improving the installation flexibility and stability of the conductive fiber 122.

[0061] In a specific embodiment, please refer to Figure 7 The portion of the conductive fiber 122 connected to the copper pad 1223 has the same dimension in the first direction Y as the copper pad 1223 in the first direction Y, so that the connection area between the conductive fiber 122 and the copper pad 1223 is larger and the connection is more stable.

[0062] In a specific embodiment, the housing assembly 11 further includes a fixing member 114, which is sleeved on one end of the plug-in terminal 1212 near the circuit board 1211 and also sleeved on one end of the circuit board 1211 near the plug-in terminal 1212. The fixing member 114 is housed in the aforementioned receiving space 113 and connected to the first housing 111 and the second housing 112 to improve the structural strength of the connection between the circuit board 1211 and the plug-in terminal 1212 and prevent the plug-in 121 from being damaged under external force.

[0063] For some implementation methods, please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 The plug terminal 1212 protrudes from the circuit board 1211 in the second direction Z. The size of the first space 1113 in the second direction Z is larger than the size of the second space 1114 in the second direction Z. The plug terminal 1212 abuts against the side wall of the first space 1113 in the first direction Y.

[0064] Optionally, the plug terminal 1212 protrudes from the circuit board 1211 in the third direction X, and the size of the first space 1113 in the third direction X is larger than the size of the second space 1114 in the second direction Z, so as to further improve the limiting effect of the sidewall of the first space 1113 on the plug terminal 1212.

[0065] By setting the plug terminal 1212 to protrude from the circuit board 1211 in the second direction Z, the size of the first space 1113 in the second direction Z is larger than the size of the second space 1114 in the second direction Z. The plug terminal 1212 abuts against the side wall of the first space 1113 in the first direction Y, so that when assembling the plug 121 and the first housing 111, the plug terminal 1212 will not be over-assembled and damage the circuit board 1211 under the limiting effect of the side wall of the first space 1113.

[0066] In the existing technology, the traditional nursing absorbent pad 20 only has a physical absorption function and cannot actively notify the user or caregiver of the presence of excrement, which leads to untimely care and can easily cause skin inflammation, infection, improper diet and other problems.

[0067] Please refer to Figure 8 and Figure 9This utility model also provides an absorbent pad monitoring device 100, including an absorbent pad 20, an absorbent pad monitor 30, and a connector 10 as described in this embodiment. The conductive fiber 122 of the connector 10 is disposed inside the absorbent pad 20, and the absorbent pad monitor 30 is electrically connected to the plug 121 of the connector 10. The absorbent pad 20 can be used in diapers. The absorbent pad 20 can use the moisture in urine and feces as a conductor. When the conductive fiber 122 comes into contact with the moisture in the absorbent pad 20, it conducts an electrical signal, which is then transmitted to the absorbent pad monitor 30 through the plug 121. The absorbent pad monitor 30 can determine whether the object in the absorbent pad 20 is urine or feces based on the received electrical signal. Furthermore, the absorbent pad monitor 30 can distinguish between normal and abnormal urine, and normal and abnormal feces based on the electrical signal, allowing caregivers and wearers to be aware of the urine and feces situation in real time and to take timely action based on the results.

[0068] In some embodiments, the absorbent pad monitor 30 includes a control module 31, a signal transmitting module 32, a signal receiving module 33, and an alarm indication module 34. The signal transmitting module 32, the signal receiving module 33, and the alarm indication module 34 are all electrically connected to the control module 31. The signal transmitting module 32 and the signal receiving module 33 are respectively electrically connected to the conductive fiber 122 of the connector 10. The control module 31 is used to output a first electrical signal to the conductive fiber 122 through the signal transmitting module 32. The signal receiving module 33 is used to receive a second electrical signal from the conductive fiber 122 and output a third electrical signal to the control module 31. The control module 31 is used to control the alarm indication module 34 to sound an alarm according to the third electrical signal.

[0069] In a specific embodiment, the conductive fiber 122 includes a first conductive fiber 1221 and a second conductive fiber 1222. Both the first conductive fiber 1221 and the second conductive fiber 1222 are connected to the aforementioned circuit board 1211 and are spaced apart from each other. The first conductive fiber 1221 is electrically connected to the signal transmitting module 32 through a connector 121, and the second conductive fiber 1222 is electrically connected to the signal receiving module 33 through a connector 121. The control module 31 outputs a first electrical signal to the first conductive fiber 1221 through the signal transmitting module 32. When the first conductive fiber 1221 and the second conductive fiber 1222 come into contact with the liquid inside the absorbent pad 20, the first conductive fiber 1221 and the second conductive fiber 1222 are connected through the liquid. Since the liquid has a low conductivity, after receiving the first electrical signal, the liquid outputs a second electrical signal with a lower voltage to the second conductive fiber 1222. The second electrical signal is transmitted along the second conductive fiber 1222 to the signal receiving module 33, and the signal receiving module 33 outputs a third electrical signal to the control module 31 according to the second electrical signal.

[0070] In a specific embodiment, the control module 31 outputs a frequency-converted electrical signal to the signal transmitting module 32. The signal transmitting module 32 outputs a first electrical signal to the first conductive fiber 1221 based on the frequency-converted electrical signal. At this time, the first electrical signal is a frequency-converted electrical signal. Under the transmission of the liquid, the voltage of the first electrical signal attenuates due to the resistance of the liquid, forming a second electrical signal, which is then transmitted to the second conductive fiber 1222. At this time, the second electrical signal is still a frequency-converted electrical signal. The second electrical signal is transmitted to the signal receiving module 33 via the second conductive fiber 1222. The signal receiving module 33 converts the second electrical signal into a third electrical signal and transmits it to the control module 31.

[0071] In a specific embodiment, the signal transmitting module 32 has filtering and output impedance matching functions. The signal transmitting module 32 can filter the frequency conversion electrical signal output by the control module 31 to obtain a broadband scanning frequency conversion electrical signal including a low-frequency band of 1KHz and a high-frequency band of 1MHz. That is, the first electrical signal includes a low-frequency band of 1KHz and a high-frequency band of 1MHz. Furthermore, the output impedance matching function of the signal transmitting module 32 can ensure the signal integrity and transmission efficiency of the first electrical signal during transmission.

[0072] In a specific embodiment, the signal transmitting module 32 includes a first capacitor C1, a first resistor R1, and a second resistor R2. One end of the first capacitor C1 is electrically connected to one end of the first resistor R1 and one end of the second resistor R2. The other end of the first capacitor C1 is electrically connected to the transmitting electrode. The other end of the first resistor R1 is used to electrically connect to the ground terminal. The other end of the second resistor R2 is electrically connected to the control module 31. The first capacitor C1 and the second resistor R2 are configured as a filter, and the first capacitor C1, first resistor R1, and second resistor R2 are configured as an output impedance matching circuit. The output impedance can be adjusted by adjusting the resistance values ​​of the first capacitor C1, the first resistor R1, and the second resistor R2.

[0073] In a specific embodiment, the signal receiving module 33 has the functions of receiving impedance matching, voltage doubler rectification and rectification filtering. The signal receiving module 33 can obtain a third electrical signal from the second electrical signal through receiving impedance matching, voltage doubler rectification and rectification filtering. The third electrical signal includes DC voltages with different voltage values. The control module 31 can analyze the liquid composition in the absorbent pad 20 according to the different DC voltage values ​​of the third electrical signal to obtain the state of urination and defecation.

[0074] In a specific embodiment, the signal receiving module 33 includes a second capacitor C2, a first diode D1, a second diode D2, a third capacitor C3, a third resistor R3, and a fourth resistor R4. One end of the second capacitor C2 is electrically connected to the receiving electrode, and the other end of the second capacitor C2 is electrically connected to one end of the third resistor R3. The other end of the third resistor R3 is electrically connected to the anode of the first diode D1 and the cathode of the second diode D2. The anode of the second diode D2 is used to be electrically connected to the ground terminal. One end of the third capacitor C3 is electrically connected to both the cathode of the first diode D1 and the control module 31. The other end of the third capacitor C3 is used to be electrically connected to the ground terminal. The fourth resistor R4 is connected in parallel with the third capacitor C3. In this configuration, the second capacitor C2, the first diode D1, and the second diode D2 are configured as a voltage doubler rectifier; the third capacitor C3 and the fourth resistor R4 are configured as a rectifier filter; and the second capacitor C2 and the third resistor R3 are configured as a receiver impedance matching circuit. The second capacitor C2 receives the second electrical signal, which is a frequency-converted electrical signal, and outputs a positive DC electrical signal to the third capacitor C3 and the fourth resistor R4 through the first diode D1 and the second diode D2. The third capacitor C3 and the fourth resistor R4 then convert the DC electrical signal into a pulse voltage third electrical signal. The third resistor R3 performs impedance matching on the second electrical signal flowing through the second capacitor C2 to improve the signal integrity and transmission efficiency of the second electrical signal during transmission.

[0075] Low-frequency signals have a large penetration depth, and their attenuation is mainly determined by conductivity, reflecting the overall conductivity of the medium. When a low-frequency signal passes through excrement, it reflects the overall conductivity of the excrement. Therefore, the voltage K-line obtained based on the speed at which excrement permeates from the surface into the absorbent pad 20 can identify the type of excrement. It should be noted that urine is mainly liquid, so it permeates through the absorbent pad 20 at a relatively fast rate, while feces have less liquid content, so they permeate through the absorbent pad 20 at a slower rate. Therefore, the type of excrement can be determined by the low-frequency signal.

[0076] High-frequency signals have a shallow penetration depth, and their attenuation is mainly affected by dielectric loss and scattering, making them more susceptible to surface composition. High-frequency signals can reflect particle interface characteristics. Urine type can be identified by its transparency and the presence or absence of sediment; stool consistency can be identified by the size of the particles and the rate of high-frequency signal attenuation. This is because a faster high-frequency signal attenuation indicates larger particles and thicker stool, while a slower attenuation indicates smaller particles and looser stool. When excrement first comes into contact with conductive fiber 122, the signal value quickly reaches a high value. Then, the moisture in the excrement permeates into the absorbent pad 20 and is absorbed, while the conductive fiber 122 becomes drier. During this process, the signal value gradually decreases, but the process is slower for stool.

[0077] In a specific embodiment, the absorbent pad monitor 30 further includes a plug-in port 35, which is electrically connected to both the signal transmitting module 32 and the signal receiving module 33. The plug-in port 35 is detachably connected to the plug-in component 121. When the absorbent pad monitor 30 is connected to the plug-in component 121 via the plug-in port 35, the absorbent pad monitor 30 can be mounted on the absorbent pad 20 to achieve wearable functionality. Since the absorbent pad 20 is a disposable consumable, it needs to be replaced after use. Therefore, the absorbent pad monitor 30 includes a plug-in port 35, which is electrically connected to both the signal transmitting module 32 and the signal receiving module 33. The plug-in port 35 is detachably connected to the plug-in component 121, allowing the absorbent pad monitor 30 to detect multiple absorbent pads 20, reducing usage costs and facilitating maintenance and replacement of the absorbent pad monitor 30.

[0078] In a specific embodiment, the absorbent pad monitor 30 further includes a power management module 36 and a wireless transmission module 37. Both the power management module 36 and the wireless transmission module 37 are electrically connected to the control module 31. The power management module 36 supplies power to the control module 31, and the wireless transmission module 37 communicates with the terminal device 300 to display the detection results on the terminal device 300. Optionally, the wireless transmission module 37 communicates with the terminal device 300 via an external server 200.

[0079] The absorbent pad monitor 30 includes a control module 31, a signal transmitting module 32, a signal receiving module 33, and an alarm indication module 34. The signal transmitting module 32, the signal receiving module 33, and the alarm indication module 34 are all electrically connected to the control module 31. The signal transmitting module 32 and the signal receiving module 33 are respectively electrically connected to the conductive fiber 122 of the connector 10. The control module 31 is used to output a first electrical signal to the conductive fiber 122 through the signal transmitting module 32. The signal receiving module 33 is used to receive a second electrical signal from the conductive fiber 122 and output a third electrical signal to the control module 31. The control module 31 is used to control the alarm indication module 34 to sound an alarm according to the third electrical signal, so that the absorbent pad monitor 30 can convert the state of urine and feces in the absorbent pad 20 into a stable and sensitive electrical signal for analysis.
