Description

Technical Field

[0001] This invention relates to the field of medical and nursing technology, specifically to a pressure-sensing intelligent urinary incontinence care device and a urination early warning method. Background Technology

[0002] Urinary incontinence is the involuntary leakage of urine. It is a common but often overlooked health problem, and it is more common in women, the elderly, and postpartum or postoperative patients. It is mainly divided into stress (leakage when coughing or sneezing), urge (uncontrollable urge to urinate), and mixed types, and is often caused by pelvic floor muscle relaxation, nerve damage, prostate problems, or bladder dysfunction.

[0003] Currently, most daily urination care for patients with urinary incontinence relies on disposable diapers or traditional urine collection devices. Traditional urine collection devices typically use underwear to maintain position and are connected to the device via a catheter, creating a nearly closed connection. This results in a closed, warm, and humid environment at the patient's urination site, similar to disposable diapers, which severely damages the patient's skin and urinary system. Furthermore, for bedridden patients with urinary incontinence, the symptoms are more complex, with uncontrollable urination requiring frequent care, significantly increasing the labor required for their care. Therefore, there is a need for a pressure-sensing intelligent urinary incontinence care device and a urination early warning method. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a pressure-sensing-based intelligent urinary incontinence care device and urination early warning method, which solves the problems of creating a closed, humid and hot environment filled with urine and its volatile substances at the patient's urination site, and the increased labor required for nursing care of bedridden patients with urinary incontinence.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A pressure-sensing-based intelligent urinary incontinence care device includes: The wearable sleeve is used to wear on the patient's lower body and is fixed to the patient's waist by binding straps on both sides. The bottom of the wearable sleeve is provided with an absorbent cotton pad for collecting urine when the patient has urinary incontinence, so as to keep the lower body dry when the patient has urinary incontinence. The front of the wearable sleeve is provided with a bladder pressure sensor to monitor changes in the muscles of the patient's bladder to determine whether urination has occurred. The collection cylinder contains two absorbent cotton blocks for absorbing urine. These two cotton blocks are connected to an absorbent pad via a liquid delivery pipe, drawing urine into the cotton blocks. A squeezing component then squeezes the cotton blocks, expelling the urine and creating negative pressure through the liquid delivery pipe to continuously draw liquid into the absorbent pad. A urine collection frame has a housing connected to its top side via a fixing buckle. The collection frame generates negative pressure inside the housing through a negative pressure assembly. This negative pressure assembly is connected via a connecting rod to a traction assembly driven by a motor. One end of the traction assembly is fitted with a suction assembly, and the other end is fitted with a hot air assembly via a connecting shaft. The collection frame is connected to a squeezing assembly via a pneumatic tube. The suction assembly is connected to the squeezing assembly via a drain tube, allowing the squeezing assembly to perform suction and squeezing operations sequentially. The hot air assembly is connected via an air supply tube to a moisture-wicking vent at the bottom front of the wearable sleeve to dry the patient's genitals.

[0006] Preferably, the squeezing assembly includes two squeezing frames located inside the collecting cylinder. An inner frame is provided on the side of the two squeezing frames that are close to each other. An air bladder is provided inside the inner frame. Connectors are fixedly connected to both sides of the air bladder. The connectors are fixedly connected to the squeezing frames so that when the air bladder expands, the connectors are pushed out, causing the squeezing frames to squeeze the absorbent cotton. Through holes are provided on the side of the two squeezing frames that are far apart from each other. The interior of the squeezing frames is hollow. The bottom side of the air bladder is fixedly connected to one end of the drain pipe. The bottom sides of the two squeezing frames are fixedly connected to one end of the air pressure pipe through branch pipes. The other end of the air pressure pipe is connected to the top of the collecting frame.

[0007] Preferably, the liquid delivery tube includes an absorbent cotton swab, one end of which is connected to the top side of two absorbent cotton blocks, and the other end of which is connected to the bottom side of the absorbent cotton pad. A protective sleeve is fitted over the outer wall of the absorbent cotton swab, one end of which is connected to the bottom side of the wearing sleeve, and the other end of which is connected to the top side of the collecting cylinder to prevent liquid leakage.

[0008] Preferably, the negative pressure assembly includes a suction cylinder located inside the housing. The bottom output end of the suction cylinder is connected to the collection frame. A suction piston slides vertically inside the suction cylinder. The top end of the suction piston is rotatably connected to one end of a connecting rod. One-way valve diaphragms are installed on the inner wall of the rear input end of the suction cylinder and the inner wall of the bottom output end of the suction cylinder to draw air into the collection frame in one direction and exhaust air to the outside in one direction.

[0009] Preferably, the traction assembly includes a turntable rotatably connected inside the collection frame. A gear is connected to one outer periphery of the turntable via toothed meshing. One side of the gear is connected to the drive end of a motor. The other side of the gear is fixedly connected to one end of a connecting shaft. A traction head is fixedly connected to the outer periphery of the other side of the turntable. The other end of the connecting rod is rotatably connected to the traction head.

[0010] Preferably, the suction assembly includes an air cylinder fixedly connected to the top side of the collection frame, an air piston sliding horizontally inside the air cylinder, a traction frame fixedly connected to the top of the air piston, the traction frame being sleeved on the outer wall of the traction head through an internal traction groove, and the other end of the drain pipe being fixedly connected to the front side of the air cylinder.

[0011] Preferably, the hot air assembly includes an air inlet cylinder fixedly connected to one end of the front side of the housing, a fan turbine rotatably connected to the front end of the air inlet cylinder, the other end of the connecting shaft being fixedly connected to the rear side of the fan turbine, an electric heating tube for heating air being installed at the rear end of the air inlet cylinder and located at the bottom side of the air inlet of the air inlet cylinder to heat the air to a suitable temperature, and the front side of the air inlet cylinder being fixedly connected to the air supply pipe.

[0012] Preferably, the outer wall of the pneumatic pipe and the drain pipe is fitted with a protective sleeve to protect the pipe body.

[0013] Preferably, a buzzer alarm for alarm purposes is installed at the other end of the front side of the housing.

[0014] A pressure-sensing-based urination early warning method includes the following steps: Step 1: When the bladder pressure sensor, which is attached to the bladder area of ​​the patient's lower body, detects changes in the muscles of that area, it immediately sends a signal to the monitoring system it is wirelessly connected to. This causes the monitoring system to drive the motor inside the housing to rotate and to sound an alarm, calling relevant nursing staff to come and provide care to the patient. Step 2: The starting motor drives the gear to rotate, and drives the turntable to rotate synchronously through the teeth on the turntable; the rotating turntable drives the traction head fixed on its front outer periphery to move together, causing it to pull the connecting rod connected to it, so that the connecting rod continuously pulls down and lifts the suction piston, causing the inside of the suction cylinder to repeat the process of suction and exhaust, so that the collection frame connected to the inside of the suction cylinder can maintain a negative pressure state. Step 3: The negative pressure environment is transmitted to the squeezing frame connected to the air pressure tube, causing negative pressure to be generated at the through groove on the squeezing frame, which in turn draws in the absorbent cotton block that is in contact with it; and the absorbent cotton block connected to the absorbent cotton pad by the absorbent cotton stick extends the connectivity of its porous structure to the absorbent cotton pad and the absorbent cotton stick; when the patient has urinary incontinence and leaves urine inside the wearing sleeve, the negative pressure generated by the connected absorbent cotton block draws the urine absorbed by the absorbent cotton pad to flow along the absorbent cotton stick to the absorbent cotton block; Step 4: After the urine is drawn into the absorbent cotton, it is again drawn in by the negative pressure from the groove on the squeezing frame until it enters the collection frame through the air pressure tube, so that the urine produced by the patient's urinary incontinence can be collected quickly, preventing it from remaining in the lower body area and keeping the lower body area dry. Step 5: The displacement traction head moves the traction frame mounted on the outer wall, causing the air piston connected to the traction frame to move back and forth in the air cylinder. The air in the air cylinder is repeatedly transported to the air bag through the air pressure pipe, and the air is drawn out from the air bag, thus causing the air bag to repeatedly expand and contract in a cycle to push and pull the connector connected to it. Step 6: Make the displacement connector synchronously pull the squeezing frame to do the same action, so that the squeezing frame continuously squeezes the absorbent cotton block, allowing the absorbent cotton block to quickly expel the urine inside; Step 7: While the absorbent cotton block is being squeezed and then restored, a negative pressure area for suction is further created, so that urine is drawn to this area more quickly, accelerating urine collection and forming a cycle of suction-squeezing-re-suction. Step 8: The rotating gear drives the fan turbine inside the air intake cylinder to rotate through the connecting shaft on the front side. This causes the fan turbine to draw in air through the air inlet on the top side of the air intake cylinder and heat the air by passing it through the electric heating tube. The heated air then flows through the air supply pipe into the dehumidification outlet and is discharged. This method of using warm, flowing air to dry the patient's genitals accelerates the drying process and reduces the damage to the patient's skin and urinary system caused by residual urine.

[0015] Working principle: When the bladder pressure sensor, which is attached to the bladder area of ​​the patient's lower body, detects muscle changes in that area, it immediately sends a signal to the wirelessly connected monitoring system. This causes the monitoring system to drive the motor inside the housing to rotate and triggers a buzzer alarm, calling for relevant nursing staff to come and care for the patient. The activated motor drives the gears to rotate, which in turn drives the turntable to rotate synchronously through the teeth on the turntable, performing the following process: The rotating turntable moves the traction head fixed to its front outer periphery, causing it to pull the connecting rod. This causes the connecting rod to continuously pull down and lift the suction piston, repeating the suction and degassing process inside the suction cylinder. This maintains a negative pressure state in the collection frame connected to the inside of the suction cylinder. This negative pressure environment is transmitted through a pneumatic pipe to the extrusion frame connected to the pneumatic pipe, creating negative pressure at the groove on the extrusion frame. This negative pressure then suctions the absorbent cotton block that it is in contact with. The absorbent cotton block, connected to the absorbent cotton pad via absorbent cotton rods, utilizes its porous structure... The connectivity extends to the absorbent pad and absorbent swab. When a patient with urinary incontinence leaves urine inside the garment, the absorbent pad absorbs the urine. The negative pressure generated by the connected absorbent pad draws the urine from the absorbent pad along the absorbent swab to the absorbent pad. After being drawn to the absorbent pad, the urine is again drawn by the negative pressure from the groove on the squeezing frame until it enters the collection frame through the air pressure tube. This allows the urine produced by the patient's urinary incontinence to be collected quickly, preventing it from stagnating in the lower body area and keeping the lower body area dry. The displacement traction head moves the traction frame mounted on the outer wall, causing the air piston connected to the traction frame to move back and forth in the air cylinder. The air in the air cylinder is repeatedly delivered to the airbag through the air pressure pipe, and the air is drawn out from the airbag. This causes the airbag to repeatedly expand and contract, pushing and pulling the connector connected to it. The displacement connector then moves the squeezing frame to do the same action, causing the squeezing frame to continuously squeeze the absorbent cotton, allowing the absorbent cotton to quickly expel the urine. As the absorbent cotton recovers after being squeezed, it further creates a negative pressure area for suction, allowing the urine to be drawn to this area more quickly, thus accelerating urine collection. The rotating gear drives the fan blade turbine inside the air intake cylinder to rotate via the connecting shaft on the front side. This causes the fan blade turbine to draw in air through the air inlet on the top side of the air intake cylinder and pass through the electric heating tube to heat the air. The heated air then flows through the air supply pipe into the dehumidification outlet and is discharged. This method uses warm, flowing air to dry the patient's genitals, accelerating the drying process and reducing the damage to the patient's skin and urinary system caused by residual urine.

[0016] This invention provides a pressure-sensing-based intelligent urinary incontinence care device and a urination early warning method. It has the following beneficial effects: 1. This invention utilizes a bladder pressure sensor to proactively warn of urinary incontinence events, transforming traditional passive care into a proactive response model. This significantly reduces the workload and frequency of rounds for nursing staff. When a urination signal is detected, the system immediately triggers an audible and visual alarm and simultaneously initiates an automatic collection program, enabling nursing staff to intervene promptly and effectively prevent skin maceration caused by prolonged urine retention. This intelligent early warning mechanism is particularly suitable for intensive care, long-term bedridden patients, and disabled patients, improving the accuracy and timeliness of nursing care while significantly saving labor costs and providing patients with safer and more humane care.

[0017] 2. This invention constructs a triple-layered protective system of negative pressure drainage, cyclic compression, and hot air drying to continuously maintain the dryness and cleanliness of the patient's perineal skin. The linked design of the absorbent pad and cotton block, combined with negative pressure transmission, ensures that urine is quickly transferred and collected in a sealed environment, preventing prolonged contact between urine and skin; the periodic dehumidification of the compression component, combined with warm airflow drying, effectively blocks the irritation of urine volatiles to the skin. This design fundamentally prevents the risk of complications such as incontinence dermatitis, urinary tract infections, and pressure sores, significantly improving the comfort and quality of life for patients who wear it long-term.

[0020] 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] Example: As one aspect of this application, embodiments of the present invention provide a pressure-sensing-based intelligent urinary incontinence care device, comprising: Please see the appendix Figure 1 Wearing sleeve 1 is used to wear on the patient's lower body and is fixed to the patient's waist by binding straps on both sides. The bottom of wearing sleeve 1 is provided with absorbent cotton pad 9 for collecting urine when the patient has urinary incontinence, so as to keep the lower body dry when the patient has urinary incontinence. The front of wearing sleeve 1 is provided with bladder pressure sensor 31, which is used to monitor the changes in the muscles of the patient's bladder to determine whether urination has occurred. Specifically, the bladder pressure sensor 31 is a non-invasive pressure monitoring device that detects the inherent resonant frequency of the bladder wall by emitting sound waves externally. Changes in bladder pressure will change the tension of the bladder wall, thereby causing a shift in the resonant frequency. The sensor analyzes this shift and converts it into a pressure value, thereby detecting changes in the bladder, i.e., the occurrence of urinary incontinence. It sends a signal to the monitoring system it is wirelessly connected to, causing the monitoring system to drive the motor inside the housing 3 to rotate.

[0022] Please see the appendix Figure 1 and attached Figure 3The collection cylinder 2 contains two absorbent cotton blocks 11 for absorbing urine. These two cotton blocks 11 are connected to an absorbent pad 9 via a liquid delivery pipe. Urine is drawn into the absorbent cotton blocks 11 and squeezed by a compression assembly, causing the urine to be expelled from the cotton blocks 11. A negative pressure is generated through the liquid delivery pipe, continuously drawing liquid into the absorbent pad 9. The liquid delivery pipe includes absorbent rods 10, one end of which is connected to the top of the two absorbent cotton blocks 11, and the other end to the bottom of the absorbent pad 9. A protective sleeve 8 is fitted over the outer wall of the absorbent rods 10, one end of which is connected to the bottom of a wearing sleeve 1, and the other end to the top of the collection cylinder 2 to prevent liquid leakage. Please see the appendix Figure 3 -Appendix Figure 5 The squeezing assembly includes two squeezing frames 12 located inside the collection cylinder 2. An inner frame 13 is provided on the side of the two squeezing frames 12 that is close to each other. An air bladder 14 is provided inside the inner frame 13. Connectors 15 are fixedly connected to both sides of the air bladder 14. The connectors 15 are fixedly connected to the squeezing frames 12 so that when the air bladder 14 expands, the connectors 15 are pushed out, causing the squeezing frames 12 to squeeze the absorbent cotton block 11. Through holes are provided on the side of the two squeezing frames 12 that is far apart from each other. The interior of the squeezing frames 12 is hollow. The bottom side of the air bladder 14 is fixedly connected to one end of the drain pipe 7. The bottom side of the two squeezing frames 12 is fixedly connected to one end of the air pressure pipe 6 through a branch pipe. The other end of the air pressure pipe 6 is connected to the top of the collection frame 4. Specifically, the absorbent pad 11 and absorbent swab 10 are both porous sponges, while the absorbent pad 9 is made of porous sponge covered with a skin-friendly cotton cloth to reduce chafing. All three structures can be disassembled and replaced to keep them clean. The porous structure makes them inconvenient to clean, so replacement is the best solution. The other parts have one-way communication channels that allow clean water to pass through quickly to achieve the cleaning effect, so they can be reused. When negative pressure is generated at the through-slot on the squeezing frame 12, it draws in the absorbent cotton block 11 that is in contact with it. The absorbent cotton block 11, which is connected to the absorbent cotton pad 9 by the absorbent cotton rod 10, extends the connectivity of its porous structure to the absorbent cotton pad 9 and the absorbent cotton rod 10. When the patient has urinary incontinence and leaves urine inside the wearing sleeve 1, it is absorbed by the absorbent cotton pad 9. The negative pressure generated by the connected absorbent cotton block 11 draws the urine in the absorbent cotton pad 9 along the absorbent cotton rod 10 to the absorbent cotton block 11. After the urine is drawn to the absorbent cotton block 11, it is again drawn in by the negative pressure from the through-slot on the squeezing frame 12 until it enters the collection frame 4 through the air pressure tube 6. This allows the urine produced by the patient's urinary incontinence to be collected quickly, preventing it from stagnating in the lower body area and keeping the lower body area dry. This method is extremely suitable for the care of patients in intensive care, long-term bedridden patients, and disabled patients. While improving the accuracy and timeliness of nursing care, it also saves a lot of labor costs and provides patients with safer and more humane nursing care.

[0023] As the airbag 14 repeatedly expands and contracts, it pushes and pulls the connector 15 connected to it, causing the displaced connector 15 to simultaneously pull the squeezing frame 12 to perform the same action. This causes the squeezing frame 12 to continuously squeeze the absorbent cotton block 11, allowing the absorbent cotton block 11 to quickly expel the urine. As the absorbent cotton block 11 recovers after being squeezed, it further creates a negative pressure area for suction, allowing the urine to be drawn to this area more quickly, thus accelerating urine collection.

[0024] Please see the appendix Figure 1 and attached Figure 6 A collection frame 4 for storing urine is provided. The top side of the collection frame 4 is connected to the housing 3 by a fixing buckle. The collection frame 4 can be disassembled by the fixing buckle for pouring out urine and cleaning. The collection frame 4 generates negative pressure inside the collection frame 4 through a negative pressure component installed inside the housing 3. The negative pressure component is connected to a traction component driven by a motor through a connecting rod 22. A suction component is installed at one end of the traction component, and a hot air component is installed at the other end of the traction component through a connecting shaft 29. The collection frame 4 is connected to a squeezing component through a pneumatic pipe 6. The suction component is connected to the squeezing component through a drain pipe 7 so that the squeezing component can perform suction and squeezing in sequence. The hot air component is connected to the moisture exhaust vent 30 at the bottom front end of the wearable sleeve 1 through an air supply pipe 5 to dry the patient's lower body. Please see the appendix Figure 6 and attached Figure 8 The negative pressure assembly includes a suction cylinder 17 located inside the housing 3. The bottom output end of the suction cylinder 17 is connected to the collection frame 4. A suction piston 18 slides vertically inside the suction cylinder 17. The top end of the suction piston 18 is rotatably connected to one end of the connecting rod 22. One-way valve diaphragms are installed on the inner wall of the rear input end and the inner wall of the bottom output end of the suction cylinder 17 to unidirectionally draw air into the collection frame 4 and unidirectionally exhaust air to the outside. The traction assembly includes a turntable 20 rotatably connected inside the collection frame 4. A gear 19 is connected to one side of the outer periphery of the turntable 20 through toothed meshing. One side of gear 19 is connected to the drive end of the motor, and the other side of gear 19 is fixedly connected to one end of connecting shaft 29. A traction head 21 is fixedly connected to the outer periphery of the other side of turntable 20. The other end of connecting rod 22 is rotatably connected to traction head 21. The suction assembly includes an air cylinder 24 fixedly connected to the top side of collection frame 4. An air piston 25 slides horizontally inside the air cylinder 24. A traction frame 23 is fixedly connected to the top of air piston 25. The traction frame 23 is sleeved on the outer wall of traction head 21 through an internal traction groove. The other end of drain pipe 7 is fixedly connected to the front side of air cylinder 24. Specifically, the starting motor drives the gear 19 to rotate, and the gears on the turntable 20 drive the turntable 20 to rotate synchronously. The rotating turntable 20 drives the traction head 21 fixed on its front outer periphery to move together, causing it to pull the connecting rod 22 connected to it. The connecting rod 22 continuously pulls down and lifts the suction piston 18, causing the suction cylinder 17 to repeat the process of suction and exhaust. This keeps the collection frame 4 connected to the inside of the suction cylinder 17 in a negative pressure state. This negative pressure environment is transmitted to the compression frame 12 connected to the air pressure pipe 6 through the air pressure pipe 6. The moving traction head 21 pulls the traction frame 23 sleeved on the outer wall, causing the air piston 25 connected to the traction frame 23 to move back and forth in the air cylinder 24. The air in the air cylinder 24 is repeatedly transported to the air bag 14 through the air pressure pipe 6. The rotating gear 19 drives the fan blade turbine 27 inside the air intake cylinder 26 to rotate through the connecting shaft 29 on the front side.

[0025] Please see the appendix Figure 9 The hot air assembly includes an air inlet cylinder 26 fixedly connected to one end of the front side of the housing 3. A fan turbine 27 is rotatably connected to the front end of the air inlet cylinder 26. The other end of the connecting shaft 29 is fixedly connected to the rear side of the fan turbine 27. An electric heating tube 28 for heating air is installed at the rear end of the air inlet cylinder 26 and is located at the bottom side of the air inlet of the air inlet cylinder 26 to heat the air to a suitable temperature. The front side of the air inlet cylinder 26 is fixedly connected to the air supply pipe 5. Specifically, the temperature of the electric heating element 28 is maintained between 30℃ and 45℃. After the air comes into contact with the electric heating element 28 and loses heat during the delivery process, it is kept at a normal temperature of 25℃ to 30℃. This prevents cold air from affecting the patient's lower body area when the air is blown towards the lower body, keeping the patient's lower body warm for drying. The rotating fan turbine 27 draws in air through the air inlet on the top side of the air inlet cylinder 26 and passes through the electric heating element 28 to heat the air. The heated air then flows through the air supply pipe 5 into the exhaust outlet 30 and is discharged. This measure of using warm, flowing air to dry the patient's lower body accelerates drying and reduces the risk of skin and urinary system damage caused by residual urine.

[0026] Please see the appendix Figure 5 and attached Figure 6 The outer walls of the air pressure pipe 6 and the drain pipe 7 are fitted with a pipe protective sleeve 16 to protect the pipe body, so as to prevent the surface of the air pressure pipe 6 and the drain pipe 7 from cracking when they are bent.

[0027] Please see the appendix Figure 1 A buzzer alarm 32 for alarm is installed on the other end of the front side of the housing 3, which will sound an alarm when it receives a warning signal from the monitoring system to remind caregivers that the patient has urinated unnaturally.

[0028] Based on the aforementioned pressure-sensing intelligent urinary incontinence care device, as another aspect of this application, a pressure-sensing urination early warning method includes the following steps: Step 1: When the bladder pressure sensor 31, which is attached to the bladder of the patient's lower body, detects the muscle changes in that area, it immediately sends a signal to the monitoring system wirelessly connected to it, causing the monitoring system to drive the motor inside the housing 3 to rotate and the buzzer alarm 32 to sound an alarm, calling relevant nursing staff to come and care for the patient. Step 2: The starting motor drives the gear 19 to rotate, and drives the turntable 20 to rotate synchronously through the teeth on the turntable 20; the rotating turntable 20 drives the traction head 21 fixed on its front outer periphery to move together, causing it to pull the connecting rod 22 connected to it, so that the connecting rod 22 continuously pulls down and lifts the suction piston 18, causing the suction cylinder 17 to repeat the suction and exhaust process, so that the collection frame 4 connected to the inside of the suction cylinder 17 can maintain a negative pressure state; Step 3: The negative pressure environment is transmitted to the squeezing frame 12 connected to the air pressure pipe 6, causing negative pressure to be generated at the through groove on the squeezing frame 12, thereby sucking up the absorbent cotton block 11 that is in contact with it; and the absorbent cotton block 11, which is connected to the absorbent cotton pad 9 through the absorbent cotton rod 10, extends the connectivity of its porous structure to the absorbent cotton pad 9 and the absorbent cotton rod 10; when the patient has urinary incontinence and leaves urine inside the wearing cover 1, the negative pressure generated by the connected absorbent cotton block 11 attracts the urine absorbed by the absorbent cotton pad 9 to flow along the absorbent cotton rod 10 to the absorbent cotton block 11; Step 4: After the urine is drawn into the absorbent cotton block 11, it is again drawn in by the negative pressure from the through groove on the squeezing frame 12 until it enters the collection frame 4 through the air pressure tube 6, so that the urine produced by the patient's urinary incontinence can be collected quickly, preventing it from stagnating in the lower body area and keeping the lower body area dry. Step 5: The displacement traction head 21 moves the traction frame 23 sleeved on the outer wall, causing the air piston 25 connected to the traction frame 23 to move back and forth in the air cylinder 24, and the air in the air cylinder 24 is repeatedly transported to the air bag 14 through the air pressure pipe 6, and the air is drawn out from the air bag 14, thereby causing the air bag 14 to repeatedly expand and contract in a cycle, so as to push and pull the connector 15 connected to it. Step 6: Make the displacement connector 15 synchronously pull the squeezing frame 12 to do the same action, so that the squeezing frame 12 continuously squeezes the absorbent cotton block 11, so that the absorbent cotton block 11 quickly discharges the urine inside. Step 7: While the absorbent cotton block 11 is being squeezed and then restored, a negative pressure area for suction is further created, so that urine is drawn to this area more quickly, accelerating urine collection and forming a cycle of suction-squeezing-re-suction. Step 8: The rotating gear 19 drives the fan turbine 27 inside the air intake cylinder 26 to rotate through the connecting shaft 29 on the front side. This causes the fan turbine 27 to draw in air through the air inlet on the top side of the air intake cylinder 26 and pass through the electric heating tube 28 to heat the air. The heated air then enters the dehumidification outlet 30 through the air supply pipe 5 and is discharged. This measure uses warm, flowing air to dry the patient's genitals, accelerating the drying process and reducing the damage to the patient's skin and urinary system caused by residual urine.

[0029] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

10. A pressure-sensing-based urination early warning method, using a pressure-sensing-based intelligent urinary incontinence care device as described in any one of claims 1 to 9, characterized in that, Includes the following steps: Step 1: When the bladder pressure sensor (31) attached to the bladder of the patient's lower body detects the muscle changes in that area, it immediately sends a signal to the monitoring system wirelessly connected to it, causing the monitoring system to drive the motor inside the housing (3) to rotate and the buzzer alarm (32) to sound an alarm, calling relevant nursing staff to come and provide care to the patient. Step 2: The starting motor drives the gear (19) to rotate, and drives the turntable (20) to rotate synchronously through the teeth on the turntable (20); the rotating turntable (20) drives the traction head (21) fixed on its front outer periphery to move together, causing it to pull the connecting rod (22) connected to it, so that the connecting rod (22) continuously pulls down and lifts the suction piston (18), so that the suction cylinder (17) repeats the process of suction and exhaust, so that the collection frame (4) connected to the inside of the suction cylinder (17) can maintain a negative pressure state; Step 3: The negative pressure environment is transmitted to the squeezing frame (12) connected to the air pressure tube (6) through the air pressure tube (6), so that negative pressure is generated at the through groove on the squeezing frame (12), which in turn draws the absorbent cotton block (11) that is in contact with it; and the absorbent cotton block (11) connected to the absorbent cotton pad (9) through the absorbent cotton rod (10) extends the connectivity of its porous structure to the absorbent cotton pad (9) and the absorbent cotton rod (10); when the patient has urinary incontinence and leaves urine inside the wearing sleeve (1), the negative pressure generated by the connected absorbent cotton block (11) draws the urine absorbed by the absorbent cotton pad (9) along the absorbent cotton rod (10) to the absorbent cotton block (11); Step 4: After the urine is drawn into the absorbent cotton (11), it is again drawn by the negative pressure from the through groove on the squeezing frame (12) until it enters the collection frame (4) through the air pressure tube (6), so that the urine produced by the patient's urinary incontinence can be collected quickly, preventing it from lingering in the lower body area and keeping the lower body area dry. Step 5: The displacement traction head (21) moves the traction frame (23) mounted on the outer wall to move the air piston (25) connected to the traction frame (23) back and forth in the air cylinder (24), and delivers the air in the air cylinder (24) back and forth to the air bag (14) through the air pressure pipe (6), and draws the air out of the air bag (14), thereby causing the air bag (14) to repeatedly expand and contract in a cycle to push and pull the connector (15) connected to it. Step 6: Make the displacement connector (15) synchronously pull the squeezing frame (12) to do the same action, so that the squeezing frame (12) continuously squeezes the absorbent cotton block (11), so that the absorbent cotton block (11) quickly discharges the urine inside; Step 7: While the absorbent cotton block (11) is squeezed and restored, a negative pressure area for suction is further created so that urine is drawn to this area more quickly, accelerating urine collection and forming a cycle of suction-squeezing-re-suction. Step 8: The rotating gear (19) drives the fan turbine (27) inside the air intake cylinder (26) to rotate through the connecting shaft (29) on the front side. This causes the fan turbine (27) to take in air through the air inlet on the top side of the air intake cylinder (26) and pass through the electric heating tube (28) to heat the air. The heated air then enters the dehumidification outlet (30) through the air supply pipe (5) and is discharged. This measure of using warm and flowing air to dry the patient's lower body accelerates the drying of the patient's lower body and reduces the damage to the patient's skin and urinary system caused by urine residue.
