Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and specifically relates to a multifunctional nursing bed for nephrology nursing. Background Art

[0002] With the continuous progress of medical technology and the increasing demand for health care by people, medical care equipment is constantly updated. As an important part of modern medical care equipment, the multifunctional nursing bed is designed more humanely and has more diverse functions to meet the nursing needs of different patients.

[0003] Patients in the nephrology department usually need long-term dialysis treatment and are often accompanied by various complications such as edema and hypertension. A multifunctional nursing bed suitable for nephrology patients should have a urine bag placement structure to facilitate the safe storage and detection of the indwelling catheter device. During the long-term indwelling of the catheter in patients, it is inevitable that the catheter becomes blocked and the urine flow is interrupted due to extrusion of the catheter. Sometimes this occurs at night when the patient is unconscious. The situation of catheter blockage or interrupted urine flow often requires a doctor to inject normal saline for flushing to remove the blockage, which is cumbersome and complex and has a delay in detection.

[0004] As shown in the patent with publication number CN108685648A, through a combined urine bag placement design, the urine bag can be properly placed, the urine volume can be detected, and the heating mechanism can be used to dry the lower body position of the patient to improve the patient's treatment experience. Although the existing indwelling catheter devices can achieve good drainage functions, when the urine bag needs to be replaced, due to sealing reasons or excessive residual urine in the catheter, it is easy to leak during replacement, which is not conducive to maintaining the cleanliness of the ward and improving the nursing efficiency of medical staff.

[0005] Therefore, it is necessary to propose a multifunctional nursing bed for nephrology nursing that can automatically detect and identify the blockage situation of the catheter, can adjust the orientation of the catheter to cooperate with the flatness change of the leg plate of the nursing bed, improve the extrusion state of the catheter; can sense the connection state of the catheter and the urine bag and reflux and store urine to reduce leakage. Summary of the Invention

[0006] To solve the above problems, the purpose of the present invention is to provide a multifunctional nursing bed for nephrology nursing. The protective sleeve not only protects the catheter but also rotates and guides to change the orientation of the catheter, and cooperates with the flatness change of the leg plate to improve the compression state of the catheter. The magnetic field sensor detects the change in the position of the magnetic ring, controls the reversing pump to reflux and collect urine, reduces urine leakage during urine bag replacement, avoids pollution of the ward environment, and improves the medical staff efficiency.

[0007] To achieve the above object, the technical solution of the present invention is as follows: A multifunctional nursing bed for nephrology nursing, including a nursing bed. The bed board of the nursing bed includes a backrest board, a waist activity board, a leg board, and a foot board that are hinged to each other from head to tail. Lifting components are hinged at the bottoms of the backrest board, the leg board, and the foot board. Guardrails are vertically detachably connected around the nursing bed. A controller is fixedly connected to the guardrail on one side of the head of the nursing bed. A plate-shaped component is provided on the leg board. An opening is formed in the middle of the guardrail, and a sleeve component is fixedly connected in the opening. A indwelling component is fixedly connected to the tail of the guardrail. The lifting component, the plate-shaped component, the sleeve component, and the indwelling component are all signal-connected to the controller.

[0008] The lifting component is used to lift the bed board and adjust the inclination of the bed board to support the patient to adjust the posture. The plate-shaped component is used to change the flatness of the leg board to accommodate the catheter and improve the squeezed state. The sleeve component is used to surround and protect the catheter, detect the extrusion pressure of the catheter, and adjust the catheter orientation to cooperate with the plate-shaped component to improve the squeezed state of the catheter. The indwelling component is used to fix the urine collection bag and detect possible blockages in the catheter, and introduce a cleaning agent to remove the blockage.

[0009] The principle of the basic solution is: The lifting component lifts part of the bed board through a mechanical structure to help the patient adjust to a comfortable posture. The plate-shaped component changes the shape of the leg board to provide an accommodating environment for the catheter. The sleeve component uses a pressure sensor to monitor the pressure of the catheter. Once the pressure exceeds the preset value, it sends a signal to the controller to control the change of the catheter orientation to improve the squeezed state. The indwelling component judges whether there is a blockage by monitoring the flow and pressure changes of the catheter combined with the signal of the pressure sensor, and automatically starts the cleaning program.

[0010] The beneficial effects of the basic solution are: 1. By cooperating the plate-shaped component with the sleeve component, the catheter direction can be adjusted and its squeezed state can be improved without disturbing the patient's rest, avoiding the influence of catheter compression on the patient's drainage and rehabilitation effect, reducing the workload of medical staff on duty, and saving medical human resources.

[0011] 2. The indwelling component can detect the separation of the urine collection bag and the catheter when the medical staff changes the urine collection bag, so as to reflux and collect the residual urine, avoiding urine leakage and polluting the patient's ward environment when changing the urine collection bag.

[0012] 3. Through the signal connection between the controller and each component, the real-time monitoring and processing of the catheter state and the blockage of the urine collection bag are realized, improving the efficiency and safety of nursing.

[0013] 4. The design of the multifunctional nursing bed fully considers the special needs of nephrology patients, and provides more comprehensive and meticulous nursing services for patients through intelligent and user-friendly designs.

[0014] Furthermore, the lifting components each include a number of hydraulic cylinders. The output ends of the hydraulic cylinders are each hinged to the bottom wall of the corresponding bed board. The hydraulic cylinders are arranged in parallel at the bottom of the nursing bed, and the hydraulic cylinders are all signal-connected to the controller.

[0015] The beneficial effects of the basic solution are as follows: 1. Intelligent control enables nursing staff to quickly and accurately adjust the state of the bed board. Through various working scenarios preset in the controller, patients or medical staff can conveniently control multiple lifting components with one key to adjust the shape of the bed board, adapting to usage scenarios such as sitting up, lying flat, and reclining, thus saving valuable time resources and improving the overall nursing efficiency.

[0016] 2. Through the precise control of the hydraulic cylinders, the bed board can be flexibly adjusted to the most suitable inclination and height for the patient, effectively alleviating the discomfort and fatigue caused by long-term bed rest.

[0017] 3. The stable lifting and intelligent control of the hydraulic cylinders reduce the accidental risks caused by improper operation, providing a safer nursing environment for patients.

[0018] Furthermore, the plate-shaped component includes a frame fixedly connected to the outside of the leg board. The frame is hinged to the two side bed boards. A main beam that divides the frame into left and right plate cavities is horizontally and fixedly connected inside the frame. The bottom wall of the main beam is hinged to the output end of the hydraulic cylinder of the corresponding leg board. Plate grooves are formed on the inner side walls of the plate cavities. A number of strip-shaped plates perpendicular to the axis of the nursing bed are slidably fitted in the plate grooves. The long sides of the strip-shaped plates in the same plate cavity are hinged to each other. A number of triangular notches that can be spliced into a rhombus are formed on the strip-shaped plates. The strip-shaped plate near the head of the bed is fixedly connected to the side wall of the plate groove;

[0019] A number of plate-shaped motors facing the left and right sides of the nursing bed are fixedly connected to the side wall of the main beam. The output shafts of the plate-shaped motors extend in parallel and are each rotatably fitted with the bottom wall of the frame. A number of cams are coaxially fixedly connected to the output shafts of the plate-shaped motors. The cams are all located at the hinge joints of the strip-shaped plates and avoid the triangular notches. The plate-shaped motors are all signal-connected to the controller.

[0020] The beneficial effects of the basic solution are as follows: 1. The design of the plate-shaped component has high flexibility and can change direction under the control of the controller to form a cross-shaped grid groove, thereby cooperating with the sleeve component to adjust the guide of the urinary catheter and accommodate the urinary catheter to improve the extrusion state of the urinary catheter, so as to automatically adjust without calling patients and medical staff, improving the treatment experience of patients.

[0021] 2. When the plate-shaped component changes direction to form a grid groove, the strip-shaped plates fold, thereby changing the contact area between the patient's thigh and the bed board, forming a ventilation corridor and ventilation openings, enhancing the ventilation effect of the patient's thigh, effectively reducing the dampness in the lower body area of the patient, and improving the comfort of the patient.

[0022] Further, the sleeve assembly includes a toothed ring rotatably connected within the through-port. A protective sleeve is fixedly connected to one side of the toothed ring close to the leg plate. Rotating teeth are provided on the outer periphery of the side of the toothed ring away from the leg plate. The rotating teeth mesh with a transmission gear. A protective motor is fixedly connected to the middle of the guardrail. The transmission gear is coaxially and fixedly connected to the output shaft of the protective motor. The protective motor is signal-connected to the controller.

[0023] The beneficial effects of the basic solution are as follows: 1. The rotating design of the protective sleeve allows the catheter to be flexibly adjusted according to the changes of the leg plate. This not only avoids excessive bending or compression of the catheter, reduces the risk of catheter blockage or damage, but also can cooperate with the variable accommodation of the catheter by the plate-shaped assembly to improve its squeezed state.

[0024] 2. The design of the sleeve assembly is compact and reasonable, which not only saves space, but also facilitates daily maintenance and cleaning work. Key components such as the protective motor and the transmission gear are all designed in a standardized way, which is easy to replace and repair.

[0025] Further, a plurality of heating wires are laid inside the protective sleeve, and the heating wires are all signal-connected to the controller.

[0026] The beneficial effects of the basic solution are as follows: 1. Under the control of the controller, the heating wires can heat the inside of the protective sleeve as needed to provide a warm environment for the catheter. This is particularly important for patients who need to have a catheter indwelling for a long time, as it can reduce catheter discomfort or dysfunction caused by cold.

[0027] 2. The warm protective sleeve can reduce the cold feeling brought by the protective sleeve to the patient and improve their comfort during the nursing process.

[0028] 3. The heating wires are signal-connected to the controller, realizing intelligent control. Nursing staff can easily adjust the working state of the heating wires, such as heating temperature, working time, etc., through the controller, so as to meet the nursing needs of different patients. This intelligent control not only improves the nursing efficiency, but also reduces the inconvenience and errors caused by manual operation.

[0029] 4. The heating wires are strictly designed and tested during laying to ensure that they will not overheat or cause safety hazards such as fires during use. At the same time, the controller also has functions such as overheat protection, further ensuring the safety of use.

[0030] Further, a plurality of pressure sensors are laid on the outer periphery of the protective sleeve. The protective sleeve is made of skin-friendly flexible material, and the pressure sensors are all signal-connected to the controller.

[0031] The beneficial effects of the basic solution are as follows: 1. The pressure sensor can monitor the pressure exerted on the protective sleeve (and the internal urinary catheter) in real time and transmit the data to the controller. This helps the controller identify the cause of the urinary catheter blockage and improve the extrusion state of the urinary catheter by rotating the protective sleeve. This intelligent response not only improves the nursing efficiency but also reduces the inconvenience and errors caused by manual operation.

[0032] 2. The skin-friendly flexible material and the soft design of the protective sleeve can reduce the irritation and pressure on the patient's skin, improving the comfort of the patient during the nursing process.

[0033] 3. The controller can record the data of the pressure sensor and perform analysis and processing. These data help the nursing staff understand the patient's body position changes, the usage of the urinary catheter, etc., providing a basis for formulating a more reasonable nursing plan.

[0034] Furthermore, the indwelling assembly includes a fixing basket, which is fixedly connected to one side of the tail of the nursing bed. A hanging rack is fixedly connected to one side of the fixing basket, and a lotion bottle is hung on the hanging rack. The urine collection bag is placed in the fixing basket. A threaded joint is connected to the urine collection bag, and the threaded joint is threadedly connected to a threaded interface. The threaded interface is connected to a urinary catheter, and the urinary catheter passes through the toothed ring and the protective sleeve and is placed in the patient's body. A reversing pump is connected to the urinary catheter. A side of the reversing pump close to the patient is connected to an indwelling cavity, and the indwelling cavity is connected to the urinary catheter. A magnetic ring is fixedly connected to the threaded joint, a sealing gasket is sleeved inside the threaded interface, and a magnetic field sensor is provided on the threaded interface. Both the reversing pump and the magnetic field sensor are signal-connected to the controller.

[0035] The beneficial effects of the basic solution are as follows: 1. The design of the indwelling assembly combines elements such as the fixing basket, the hanging rack, the lotion bottle, and the urine collection bag skillfully, forming a compact and functional whole. This not only saves space but also improves the nursing efficiency.

[0036] 2. The design of the threaded joint and the threaded interface makes the connection and disassembly of the urinary catheter simple and fast, reducing the operation difficulty of the nursing staff. At the same time, the setting of the magnetic ring and the magnetic field sensor endows the disassembly induction function, which can collect the residual urine by reflux through the controller during disassembly, avoiding urine leakage and reducing environmental pollution.

[0037] 3. The design of the indwelling cavity provides a corresponding accommodation space for the reflux collection of urine, avoiding the pain caused by the reflux impact on the patient's body. At the same time, the use of the sealing gasket ensures the tightness of the connection and prevents urine leakage.

[0038] Furthermore, a lotion tube is connected to the lotion bottle, and the lotion tube is connected to the input end of the reversing pump.

[0039] The beneficial effects of the basic solution are as follows: 1. By connecting the lotion bottle to the reversing pump through the lotion tube, automatic supply of lotion is achieved. When it is necessary to clear the blockage of the urinary catheter, the controller can instruct the reversing pump to start, draw the lotion out of the lotion bottle, and transport it to the designated position through the urinary catheter. This not only simplifies the flushing operation but also improves the efficiency and accuracy of flushing.

[0040] 2. The automatic lotion supply reduces the manual operation of nursing staff and lowers the risks caused by improper operation. At the same time, it also reduces the labor intensity of nursing staff and improves work efficiency.

[0041] 3. The automatic flushing process can more precisely control the amount and flow rate of the flushing fluid, avoiding discomfort or complications caused by too much or too little flushing fluid. In addition, the stable operation of the reversing pump also ensures the smooth progress of the flushing process and reduces the discomfort of the patient.

[0042] Furthermore, pressure equalizing valves are connected to both the lotion tube and the urine collection bag.

[0043] The beneficial effects of the basic solution are as follows: The setting of the pressure equalizing valve helps to maintain the balance and stability of the internal pressure of the lotion tube and the urine collection bag. During medical care, the pressure in the patient's body may change, and the pressure equalizing valve can automatically adjust to ensure that the internal pressure of the lotion tube and the urine collection bag is consistent with the pressure in the patient's body, thus avoiding problems such as liquid leakage or backflow caused by pressure differences.

[0044] Furthermore, the waist activity board includes a number of activity bars, and springs are fixedly connected between the radial sides of the activity bars.

[0045] The beneficial effects of the basic solution are as follows: 1. The combined design of the activity bars and the springs enables the waist activity board to be flexibly adjusted according to the natural curve and movement requirements of the waist. The elastic effect of the springs can provide additional supporting force to help disperse the pressure on the waist, thus reducing the burden on the waist. At the same time, the design of the activity bars allows the waist to move freely within a certain range, maintaining the flexibility of the waist.

[0046] 2. The elastic effect of the springs can buffer the impact force on the waist and reduce the waist fatigue and discomfort caused by maintaining the same posture for a long time. The design of the activity bars also makes the waist activity board more conform to the waist curve, improving the wearing comfort. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0055] The following is a further detailed description through specific implementation manners:

[0056] Embodiment 1

[0057] Basically as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 : A multifunctional nursing bed for nephrology nursing, including a nursing bed 1. The bed board of the nursing bed 1 includes a backrest 7, a waist movable board, a leg board and a foot board 2 that are hinged to each other from head to tail. Lifting components are hinged to the bottoms of the backrest 7, the leg board and the foot board 2. Guardrails 8 are vertically and detachably bolted around the nursing bed 1. A controller 9 is adhered to the guardrail 8 on one side of the head of the nursing bed 1. A plate-shaped component is provided on the leg board. A through hole 11 is opened in the middle of the guardrail 8. A sleeve component is rotatably sleeved in the through hole 11. An indwelling component is welded to the tail of the guardrail 8. The lifting component, the plate-shaped component, the sleeve component and the indwelling component are all in signal connection with the controller 9.

[0058] The lifting assembly is used to lift the bed board and adjust the inclination of the bed board to support the patient in adjusting the posture. The plate-shaped assembly is used to change the flatness of the leg board to accommodate the urinary catheter 22 and improve the squeezed state. The sleeve assembly is used to surround and protect the urinary catheter 22, detect the extrusion pressure of the urinary catheter 22, and adjust the orientation of the urinary catheter 22 to cooperate with the plate-shaped assembly to improve the squeezed state of the urinary catheter 22. The indwelling assembly is used to fix the urine collection bag 18 and detect possible blockages in the urinary catheter 22, and introduce a cleaning agent to remove the blockage.

[0059] The lifting assemblies each include a number of hydraulic cylinders 10. The output ends of the hydraulic cylinders 10 are each hinged to the bottom wall of the corresponding bed board. The hydraulic cylinders 10 are arranged in parallel at the bottom of the nursing bed 1, and the hydraulic cylinders 10 are each signal-connected to the controller 9. The plate-shaped assembly includes a frame 4 welded to the outside of the leg board. The frame 4 is hinged to the two side bed boards. A main beam 3 that divides the frame 4 into left and right plate cavities is horizontally welded inside the frame 4. The bottom wall of the main beam 3 is hinged to the output end of the hydraulic cylinder 10 of the corresponding leg board. Plate grooves are opened on the inner side walls of the plate cavities. A number of strip plates 20 perpendicular to the axis of the nursing bed 1 are slidably fitted in the plate grooves. The long sides of the strip plates 20 in the same plate cavity are hinged to each other. A number of triangular notches that can be spliced into a rhombus are opened on the strip plates 20. The strip plate 20 near the head of the bed is welded to the side wall of the plate groove;

[0060] A number of plate-shaped motors 29 facing the left and right sides of the nursing bed 1 are welded to the side wall of the main beam 3. The output shafts of the plate-shaped motors 29 extend in parallel and are each rotatably fitted to the bottom wall of the frame 4. A number of cams 30 are coaxially welded to the output shafts of the plate-shaped motors 29. The cams 30 are each located at the hinge joints of the strip plates 20 and avoid the triangular notches. The plate-shaped motors 29 are each signal-connected to the controller 9.

[0061] The sleeve assembly includes a toothed ring 12 rotatably connected in the through hole 11. A protective sleeve 13 is bonded to one side of the toothed ring 12 close to the leg board. Rotating teeth are opened on the outer periphery of the toothed ring 12 on the side away from the leg board. The rotating teeth are engaged with a transmission gear 14. A protective motor 15 is fixedly connected to the middle of the guardrail 8. The transmission gear 14 is coaxially welded to the output shaft of the protective motor 15. The protective motor 15 is signal-connected to the controller 9. A number of heating wires are laid inside the protective sleeve 13, and the heating wires are each signal-connected to the controller 9. A number of pressure sensors are laid on the outer periphery of the protective sleeve 13. The protective sleeve 13 is made of a skin-friendly flexible material, and the pressure sensors are each signal-connected to the controller 9.

[0062] The waist movable board includes a number of movable strips 5, and springs 6 are welded between the radial sides of the movable strips 5.

[0063] The specific implementation process is as follows: During the long-term indwelling catheterization of patients in the nephrology department, not only does the nursing bed 1 need to be able to change its shape with one key to support the living needs of patients, such as sitting up, lying flat, and reclining. When the patient accidentally squeezes the catheter 22, it is best to adjust the squeezed state of the catheter 22 in a non-intrusive manner to reduce the probability of catheter 22 blockage and improve the medical staff efficiency.

[0064] The patient or medical staff can operate the hydraulic cylinder 10 on the controller 9 to change the parallel angle of each bed board of the nursing bed 1, so as to combine and form the shape of a reclining chair or bed suitable for the patient to sit and lie on. These combined shapes are set as preset parameters. The patient or medical staff only need to operate with one key on the controller 9 to change the shape of the bed board into the desired combination, without the need to separately adjust the parameters of the hydraulic cylinder 10. The stable deformation of the hydraulic cylinder 10 during the change of the bed board shape can reduce the jitter and bump during the deformation of the bed board, thereby improving the patient's experience of controlling the deformation of the nursing bed 1.

[0065] Since patients in the nephrology department often have indwelling catheters 22, although the catheter 22 often passes above the patient's leg, during the unconscious sleep time at night, the patient's turning over and posture changes may pull or squeeze the catheter 22, resulting in the blockage of the catheter 22, and then causing serious treatment interference. The traditional method of adjusting the catheter 22 at night can only wait for the medical staff or the patient to discover, which not only causes a delay in adjustment but also disturbs the patient's sleep.

[0066] When the present invention is in use, if the patient's posture changes and the catheter 22 is pressed under the leg or for other reasons that cause the catheter 22 to be blocked, the indwelling component can detect the flow rate and pressure changes in the catheter 22. Then, the controller 9 detects the external pressure exerted on the catheter 22 through the pressure sensor on the protective sleeve 13, and comprehensively judges the cause of the catheter 22 blockage. If the catheter 22 is blocked while the flow rate decreases and the pressure increases, and the pressure sensor does not detect the pressure change of the protective sleeve 13 being squeezed, it is determined that the blockage is due to other reasons. The indwelling component flushes the blocked part to remove the blockage. If the catheter 22 is blocked due to external pressure, the protective motor 15 of the sleeve component starts to rotate the toothed ring 12 to rotate the protective sleeve 13, so that the pressed catheter 22 and the protective sleeve 13 produce a guiding change. At the same time, the plate-shaped motor 29 in the plate-shaped component starts to rotate the cam 30, and the cam 30 alternately jacks up the hinge joints of the strip plate 20 to form a wavy fold, forming a transverse groove on the surface of the leg plate. At the same time, the triangular notches 21 are symmetrically folded, and the triangular notches 21 originally spliced into a rhombus form a longitudinal groove. The combination of the grooves in two directions forms a cross-shaped grid groove, so as to accommodate the catheter 22 during the guiding change process of the catheter 22 and the protective sleeve 13, reduce the pressure of the catheter 22 being pressed by the patient's leg, and restore the conduction of the catheter 22. This process is automatically detected and adjusted by the controller 9, without the need for medical staff to discover the blockage situation and then deal with it, nor does it require medical staff to wake up the patient to adjust the posture. This undoubtedly reduces the disturbance to the patient's sleep, improves the medical efficiency, and reduces the heavy work of medical staff. The heating wire inside the protective sleeve 13 heats the protective sleeve 13 to near body temperature and the skin-friendly elastic material of the protective sleeve 13 reduces the foreign body sensation of the contact between the protective sleeve 13 and the patient's skin, improving the comfort of the patient staying in bed.

[0067] Embodiment 2

[0068] The difference from the above embodiment is that as shown in the attached Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7As shown in the figure: The indwelling component includes a fixing basket 19, which is welded to one side of the tail of the nursing bed 1. A hanging rack is welded to one side of the fixing basket 19, and a lotion bottle 17 is hung on the hanging rack. A urine collection bag 18 is installed in the fixing basket 19. A threaded joint 25 is connected to the urine collection bag 18. The threaded joint 25 is threadedly connected to a threaded interface 26. The threaded interface 26 is connected to a urinary catheter 22. The urinary catheter 22 passes through the gear ring 12 and the protective sleeve 13 and is placed in the patient's body. A reversing pump 24 is connected to the urinary catheter 22. One side of the reversing pump 24 close to the patient is connected to an indwelling cavity 23. The indwelling cavity 23 is connected to the urinary catheter 22. A magnetic ring 28 is bonded to the threaded joint 25. A sealing washer 31 is sleeved inside the threaded interface 26. A magnetic field sensor 27 is bonded to the threaded interface 26. Both the reversing pump 24 and the magnetic field sensor 27 are signal-connected to the controller 9. A lotion tube 16 is connected to the lotion bottle 17. The lotion tube 16 is connected to the input end of the reversing pump 24. Equalizing valves are connected to both the lotion tube 16 and the urine collection bag 18.

[0069] The specific implementation process is as follows: Although the connection between the existing urinary catheter 22 and the urine adding bag can maintain a stable and sealed connection for a long time, during the process of replacing the urine collection bag 18, the residual urine may leak from the urinary catheter 22, polluting the ward environment and increasing the cleaning burden on medical staff.

[0070] A magnetic ring 28 and a magnetic field sensor 27 are arranged on the threaded joint 25 and the threaded interface 26. The magnetic field sensor 27 is a miniature bellows structure. During the process of the medical staff unscrewing the joint, the magnetic field sensor 27 senses the change in the magnetic field when the magnetic ring 28 moves away, and thus transmits a signal to the controller 9. The controller 9 controls the reversing pump 24 to suck the residual urine in the urinary catheter 22 between the reversing pump 24 and the threaded interface 26 into the indwelling cavity 23, thereby avoiding urine leakage when replacing the urine collection bag 18 and realizing the function of automatically stopping the leakage of the urinary catheter 22.

[0071] When the catheter 22 is blocked, the reversing pump 24 can firstly conduct the flow in the forward direction, and judge whether the blockage occurs according to the flow rate and pressure during the diversion. When the diversion is not smooth and the pressure reaches the threshold value, it means that the catheter 22 is blocked. At this time, the controller 9 combines the pressure sensor signal on the protective sleeve 13 to comprehensively judge the blockage mode, and combines the flow rate and pressure in the catheter 22, as well as the pressure sensor data. If the flow rate decreases and the pressure increases, and the pressure sensor detects the pressure state, it is due to the compression of the patient's limbs that the catheter 22 is squeezed and blocked. The controller 9 controls the protection motor 15 and the plate motor 29 to adjust The catheter 22 is guided and accommodated in the grid groove formed by the strip plate 20 to improve the squeezing state. If the pressure sensor does not detect the pressurized state, it is because the catheter 22 is blocked by foreign matter. The lotion in the lotion bottle 17, generally saline, is pumped into the catheter 22 through the reversing pump 24. By continuously reversing and pumping the cleaning agent back and forth, the blockage is pressurized to flush and clear the blockage, and the catheter 22 is reopened without the need for medical staff to use a syringe for manual catheterization, which greatly reduces the effect of medical human resources, enhances the flushing reaction speed of the catheter 22 blockage, and reduces the probability of adverse consequences.
