Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically a multifunctional nursing bed for nephrology care. Background Technology

[0002] With the continuous advancement of medical technology and the increasing demand for health care, medical care equipment is also constantly being updated and upgraded. As an important component of modern medical care equipment, the multifunctional nursing bed is designed with greater humanization and offers more diverse functions to meet the care needs of different patients.

[0003] Nephrology patients often require long-term dialysis treatment and frequently experience various complications such as edema and hypertension. A suitable multi-functional nursing bed for nephrology patients should have a urine collection bag placement structure for convenient and safe storage and monitoring of the catheterization device. During long-term indwelling catheterization, catheter blockage and catheter interruption due to compression are inevitable, sometimes occurring at night when the patient is unconscious. Catheter blockage or interruption often requires doctors to inject saline solution to flush and clear the blockage, a cumbersome and delayed process.

[0004] As shown in patent CN108685648A, a modular urine collection bag placement design allows for proper placement of the bag, monitoring of urine volume, and drying of the patient's genital area via a heating mechanism, improving the patient's treatment experience. While existing indwelling catheters can achieve good drainage, leaks are common during bag replacement due to sealing issues or excessive residual urine in the catheter, hindering ward hygiene and reducing the efficiency of nursing care.

[0005] Therefore, it is necessary to propose a multifunctional nursing bed for nephrology care that can automatically detect and identify catheter blockage, adjust the catheter guide to match the flatness of the nursing bed leg board to improve the catheter compression state, and sense the connection status of the catheter and urine collection bag and return and preserve urine to reduce leakage. Summary of the Invention

[0006] To address the aforementioned problems, the present invention aims to provide a multifunctional nursing bed for nephrology care. The protective sleeve not only protects the urinary catheter but also allows for rotational guidance to change its orientation. Combined with the flatness of the leg panel, this improves the pressure on the catheter. A magnetic field sensor detects changes in the position of the magnetic ring, controlling the reversing pump to collect urine, reducing leakage during urine bag changes, preventing contamination of the ward environment, and improving medical efficiency.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: A multifunctional nursing bed for nephrology care, comprising a nursing bed, the bed board of which includes a backrest board, a lumbar support board, a leg board, and a foot board that are hinged together from head to tail. Lifting components are hinged to the bottom of the backrest board, leg board, and foot board. Guardrails are vertically and detachably connected around the nursing bed. A controller is fixedly connected to the guardrail on one side of the headboard. A plate-shaped component is provided on the leg board. An opening is opened in the middle of the guardrail, and a sleeve component is fixedly connected inside the opening. An indwelling component is fixedly connected to the tail of the guardrail. The lifting component, plate-shaped component, sleeve component, and indwelling component are all signal-connected to the controller.

[0008] The lifting assembly is used to raise the bed board and adjust its tilt to support the patient's posture adjustment. The plate assembly is used to change the flatness of the leg plate to accommodate the urinary catheter and improve its compression condition. The sleeve assembly is used to surround and protect the urinary catheter, detect the compression pressure on the urinary catheter, and adjust the catheter guide to cooperate with the plate assembly to improve the compression condition of the urinary catheter. The indwelling assembly is used to fix the urine collection bag and detect any possible blockages in the urinary catheter, and introduce cleaning agent to clear the blockages.

[0009] The basic principle of the solution is as follows: The lifting component uses a mechanical structure to elevate the bed board, helping the patient adjust to a comfortable position. The plate-shaped component changes the shape of the leg plate to provide a suitable environment for the catheter. The cannula assembly uses pressure sensors to monitor the pressure on the catheter; once the pressure exceeds a preset value, it sends a signal to the controller to control the catheter's direction and improve the compression condition. The indwelling component monitors the catheter's flow and pressure changes in conjunction with the pressure sensor signals to determine if there is a blockage and automatically initiates a cleaning procedure.

[0010] The beneficial effects of the basic solution are: 1. By using the plate-shaped component in conjunction with the cannula component, the direction of the urinary catheter can be adjusted and its compression status improved without disturbing the patient's rest. This avoids the compression of the urinary catheter affecting the patient's drainage and recovery effect, and also reduces the workload of medical staff on duty, saving medical human resources.

[0011] 2. The indwelling device can detect the separation of the urine collection bag and the catheter when medical staff change the urine collection bag, thereby collecting residual urine back and preventing urine leakage and contamination of the patient's ward environment when changing the urine collection bag.

[0012] 3. By connecting the controller with the signals of each component, real-time monitoring and handling of the status of the urinary catheter and the blockage of the urine collection bag are realized, improving the efficiency and safety of nursing care.

[0013] 4. The multi-functional nursing bed is designed with the special needs of nephrology patients in mind. Through intelligent and humanized design, it provides patients with more comprehensive and meticulous nursing services.

[0014] Furthermore, each lifting component includes several hydraulic cylinders, the output ends of which are 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 each hydraulic cylinder is connected to the controller signal.

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

[0016] 2. Through precise control of the hydraulic cylinder, the bed board can be flexibly adjusted to the most suitable tilt and height for the patient, effectively relieving the discomfort and fatigue caused by prolonged bed rest.

[0017] 3. The smooth lifting and intelligent control of the hydraulic cylinder reduce the risk of accidents caused by improper operation, providing a safer nursing environment for patients.

[0018] Furthermore, the panel assembly includes a frame fixedly connected to the outside of the leg panel, the frame is hinged to the two side panels, a main beam that divides the frame into left and right panel cavities is horizontally fixedly connected inside the frame, the bottom wall of the main beam is hinged to the hydraulic cylinder output end of the corresponding leg panel, the inner side wall of each panel cavity has a panel groove, and several strip panels perpendicular to the axis of the nursing bed are slidably fitted in each panel groove, the long sides of the strip panels in the same panel cavity are hinged to each other, and several triangular notches that can be spliced ​​together to form a rhombus are opened on each strip panel, and the strip panel near the head of the bed is fixedly connected to the side wall of the panel groove;

[0019] Several 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 parallel and are rotatably engaged with the bottom wall of the frame. Several cams are coaxially fixedly connected to the output shafts of the plate-shaped motors. The cams are all located at the hinge of the strip plate and avoid the triangular notch. The plate-shaped motors are all connected to the controller signal.

[0020] The beneficial effects of the basic solution are: 1. The design of the plate-shaped component is highly flexible. It can change direction under the control of the controller to form a cross-shaped groove, thereby cooperating with the cannula component to adjust the guide of the catheter and accommodate the catheter to improve the compression state of the catheter. This allows for automatic adjustment without calling the patient or medical staff, thus improving the patient's treatment experience.

[0021] 2. When the plate-shaped component changes direction to form a grid, the strip plate folds to change the contact area between the patient's thigh and the bed board, forming ventilation corridors and vents, enhancing the ventilation effect at the patient's thigh, effectively reducing moisture in the patient's lower body area, and improving the patient's comfort.

[0022] Furthermore, the sleeve assembly includes a toothed ring rotatably connected within the opening. A protective sleeve is fixedly connected to the side of the toothed ring near the leg plate. Rotating teeth are opened on the outer periphery of the side of the toothed ring away from the leg plate, and 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 fixedly connected to the output shaft of the protective motor, and the protective motor is signal-connected to the controller.

[0023] The beneficial effects of the basic design are: 1. The rotating design of the protective sleeve allows the catheter to be flexibly adjusted according to the changes in the leg plate, which not only avoids excessive bending or pressure on the catheter and reduces the risk of catheter blockage or damage, but also allows the deformation of the plate assembly to accommodate the catheter and improve its compression state.

[0024] 2. The bushing assembly features a compact and rational design, saving space and facilitating daily maintenance and cleaning. Key components such as the motor and transmission gears utilize standardized designs, making them easy to replace and repair.

[0025] Furthermore, several heating wires are laid inside the protective sleeve, and all the heating wires are connected to the controller signal.

[0026] The beneficial effects of the basic solution are: 1. Under the control of the controller, the heating wire can heat the inside of the protective sheath as needed, providing a warm environment for the catheter. This is especially important for patients who need long-term indwelling catheters, as it can reduce catheter discomfort or dysfunction caused by cold.

[0027] 2. A warm protective sleeve can reduce the cold sensation felt by the patient due to the sleeve, thus improving their comfort during the nursing process.

[0028] 3. The heating wire is connected to the controller via signal transmission, enabling intelligent control. Nursing staff can easily adjust the heating wire's operating status, such as heating temperature and operating time, through the controller to meet the different nursing needs of patients. This intelligent control not only improves nursing efficiency but also reduces the inconvenience and errors caused by manual operation.

[0029] 4. The heating wires undergo rigorous design and testing during installation to ensure they will not overheat or cause fires during use. The controller also features overheat protection, further enhancing safety.

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

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

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

[0033] 3. The controller can record, analyze, and process data from the pressure sensors. This data helps nursing staff understand changes in patient position, catheter usage, etc., providing a basis for developing more appropriate nursing plans.

[0034] Furthermore, the indwelling assembly includes a fixed basket, which is fixedly connected to one side of the end of the nursing bed. A hanging rack is fixedly connected to one side of the fixed basket, on which a wash bottle is hung. A urine collection bag is placed inside the fixed basket, and a threaded connector is connected to the urine collection bag. The threaded connector is threaded to a threaded interface, which is connected to a urinary catheter. The urinary catheter passes through a toothed ring and a protective sleeve and is inserted into the patient's body. A reversing pump is connected to the urinary catheter. The side of the reversing pump closest to the patient is connected to an indwelling cavity, which is connected to the urinary catheter. A magnetic ring is fixedly connected to the threaded connector, and a sealing gasket is fitted inside the threaded interface. A magnetic field sensor is provided on the threaded interface. Both the reversing pump and the magnetic field sensor are connected to the controller signal.

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

[0036] 2. The threaded connector and threaded interface design makes connecting and disconnecting the urinary catheter simple and quick, reducing the operational difficulty for nursing staff. Meanwhile, the magnetic ring and magnetic field sensor provide a disassembly sensing function, enabling the controller to collect residual urine during disassembly, preventing leakage and reducing environmental pollution.

[0037] 3. The indwelling cavity design provides adequate space for urine reflux collection, preventing backflow from impacting the patient and causing pain. Simultaneously, the use of a sealing gasket ensures a tight connection, preventing urine leakage.

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

[0039] The beneficial effects of the basic solution are: 1. By connecting the wash bottle to the reversing pump via the wash tubing, automated wash supply is achieved. When catheter blockage needs to be cleared, the controller can instruct the reversing pump to start, drawing the wash from the wash bottle and delivering it to the designated location through the catheter. This not only simplifies the flushing operation but also improves the efficiency and accuracy of flushing.

[0040] 2. Automated detergent dispensing reduces manual operation by nursing staff, lowering the risks associated with improper operation. It also reduces the workload of nursing staff and improves work efficiency.

[0041] 3. The automated flushing process allows for more precise control of the amount and flow rate of the flushing fluid, avoiding discomfort or complications caused by too much or too little fluid. Furthermore, the stable operation of the reversing pump ensures a smooth flushing process, reducing patient discomfort.

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

[0043] The beneficial effects of the basic approach are: the equalizing valve helps maintain a balance and stability of pressure within the wash tubing and urine collection bag. During medical care, the patient's internal pressure may fluctuate, and the equalizing valve automatically adjusts to ensure that the pressure inside the wash tubing and urine collection bag matches the patient's internal pressure, thus preventing fluid leakage or backflow problems caused by pressure differences.

[0044] Furthermore, the waist movable plate includes several movable strips, and springs are fixedly connected between the radial sides of the movable strips.

[0045] The beneficial effects of the basic design are: 1. The combination of the movable strip and spring design allows the lumbar support plate to be flexibly adjusted according to the natural curve of the waist and movement needs. The elasticity of the spring provides additional support, helping to distribute pressure on the waist and thus reducing the burden on the waist. At the same time, the design of the movable strip allows the waist to move freely within a certain range, maintaining the flexibility of the waist.

[0046] 2. The elasticity of the springs can cushion the impact on the waist, reducing fatigue and discomfort caused by maintaining the same posture for a long time. The design of the movable strip also makes the lumbar support plate fit the waist curve more closely, improving wearing comfort. Attached Figure Description

[0055] The following detailed description illustrates the specific implementation method:

[0056] Example 1

[0057] The basics are as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown: A multifunctional nursing bed for nephrology care includes a nursing bed 1. The bed board of the nursing bed 1 includes a backrest board 7, a lumbar support board, a leg board, and a footboard 2 that are hinged together from head to tail. Lifting components are hinged to the bottom of the backrest board 7, the leg board, and the footboard 2. Guardrails 8 are vertically and detachably bolted around the nursing bed 1. A controller 9 is attached 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. An opening 11 is opened in the middle of the guardrail 8. A sleeve component is rotatably fitted inside the opening 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 signal connected to the controller 9.

[0058] The lifting assembly is used to lift the bed board and adjust its inclination to support the patient's posture adjustment. The plate assembly is used to change the flatness of the leg plate to accommodate the urinary catheter 22 and improve its compression condition. The sleeve assembly is used to surround and protect the urinary catheter 22, detect the compression pressure on the urinary catheter 22, and adjust the guide of the urinary catheter 22 to cooperate with the plate assembly to improve the compression condition of the urinary catheter 22. The indwelling assembly is used to fix the urine collection bag 18 and detect any possible blockages in the urinary catheter 22, and introduce cleaning agent to clear the blockages.

[0059] Each lifting component includes several hydraulic cylinders 10, the output ends of which are 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 each hydraulic cylinder 10 is connected to the controller 9 via signal. The plate-shaped component 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 is horizontally welded inside the frame 4, dividing the frame 4 into left and right plate cavities. The bottom wall of the main beam 3 is hinged to the output end of the hydraulic cylinder 10 corresponding to the leg board. The inner side wall of each plate cavity has a plate groove. Several strip plates 20 perpendicular to the axis of the nursing bed 1 are slidably fitted in the plate groove. The long sides of the strip plates 20 in the same plate cavity are hinged to each other. Several triangular notches that can be spliced ​​together to form a rhombus are opened on each strip plate 20. The strip plates 20 near the head of the bed are welded to the side wall of the plate groove.

[0060] Several plate 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 motors 29 extend parallel and are rotatably engaged with the bottom wall of the frame 4. Several cams 30 are coaxially welded on the output shafts of the plate motors 29. The cams 30 are all located at the hinge of the strip plate 20 and avoid the triangular notch. The plate motors 29 are all connected to the controller 9.

[0061] The sleeve assembly includes a toothed ring 12 rotatably connected within the opening 11. A protective sleeve 13 is bonded to the side of the toothed ring 12 closest to the leg plate. Rotating teeth are formed on the outer periphery of the toothed ring 12 away from the leg plate, meshing with a transmission gear 14. A protective motor 15 is fixedly connected to the center of the guardrail 8. The transmission gear 14 and the output shaft of the protective motor 15 are coaxially welded together. The protective motor 15 is signal-connected to the controller 9. Several heating wires are laid inside the protective sleeve 13, all of which are signal-connected to the controller 9. Several 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 all pressure sensors are signal-connected to the controller 9.

[0062] The waist movable plate includes several 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 nephrology patients, the nursing bed 1 needs to be able to change its shape with one click to support the patient's living needs, 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-disturbing way to reduce the probability of catheter 22 blockage and improve medical and nursing efficiency.

[0064] Patients 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, thereby combining them to form a shape suitable for the patient to sit or lie on. These combined shapes are set as preset parameters. Patients or medical staff only need to operate the controller 9 with one button to change the shape of the bed board to the desired combination, without having to adjust the parameters of the hydraulic cylinder 10 separately. The stable deformation of the hydraulic cylinder 10 during the bed board shape change can reduce the shaking and bumping during the bed board deformation process, thereby improving the patient's experience in controlling the deformation of the nursing bed 1.

[0065] Because nephrology patients often have indwelling urinary catheters 22, although the catheter 22 usually passes above the patient's legs, during unconscious sleep at night, the patient's movements of turning over and changing posture may pull or squeeze the catheter 22, causing the catheter 22 to become blocked, which in turn causes serious interference with treatment. The traditional method of adjusting the catheter 22 at night can only wait for medical staff or the patient to notice, which not only causes delays in adjustment, but also disturbs the patient's sleep.

[0066] When the patient changes posture, causing the catheter 22 to be pressed under their legs, or due to other reasons, the catheter 22 becomes blocked. The indwelling assembly can detect changes in flow and pressure in the catheter 22. The controller 9 then uses a pressure sensor on the protective sleeve 13 to detect the external pressure on the catheter 22 and comprehensively determines the cause of the blockage. If the flow rate decreases, the pressure increases, and the catheter becomes blocked, but the pressure sensor does not detect any pressure change due to the compression of the protective sleeve 13, the blockage is determined to be due to other reasons. The indwelling assembly then flushes and clears the blockage. If the blockage is caused by external pressure, the protective motor 15 of the sleeve assembly starts rotating the gear ring 12, causing the protective sleeve 13 to rotate, thus causing a guiding change between the compressed catheter 22 and the protective sleeve 13. Simultaneously, the plate motor 29 in the plate assembly starts rotating the cam 30, causing the cam 30 to alternately lift the hinge of the strip plate 20, forming wave-shaped folds. This creates a transverse groove on the surface of the leg plate. At the same time, the triangular notch 21 folds symmetrically, transforming the originally rhomboid triangular notch 21 into a longitudinal groove. The grooves in both directions combine to form a cross-shaped grid, thus accommodating the catheter 22 during the guiding changes of the catheter and protective sleeve 13. This reduces the pressure on the catheter 22 from the patient's leg, restoring the catheter's conductivity. This process is automatically completed by the controller 9, eliminating the need for medical staff to detect and treat blockages or wake the patient to adjust their posture. This undoubtedly reduces disruption to the patient's sleep, improves medical efficiency, and reduces the workload of medical staff. The heating wire inside the protective sleeve 13 heats it to near body temperature, and the skin-friendly elastic material of the protective sleeve 13 reduces the foreign body sensation when in contact with the patient's skin, improving the patient's comfort while lying in bed.

[0067] Example 2

[0068] The difference from the above embodiments is that, as shown in the appendix Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7As shown: The indwelling assembly includes a fixed basket 19, which is welded to one side of the rear of the nursing bed 1. A hanging rack is welded to one side of the fixed basket 19, on which a wash bottle 17 is hung. A urine collection bag 18 is installed inside the fixed basket 19. A threaded connector 25 is connected to the urine collection bag 18. A threaded interface 26 is threaded to the threaded connector 25. A catheter 22 is connected to the threaded interface 26. The catheter 22 passes through a toothed ring 12 and a protective sleeve 13 and is inserted into the patient's body. A reversing pump 24 is connected to the catheter 22. An indwelling cavity 23 is connected to the side of the reversing pump 24 closest to the patient. The indwelling cavity 23 is connected to the catheter 22. A magnetic ring 28 is bonded to the threaded connector 25. A sealing gasket 31 is fitted 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 wash tube 16 is connected to the wash bottle 17, and the wash tube 16 is connected to the input end of the reversing pump 24. Both the wash tube 16 and the urine collection bag 18 are connected to pressure equalization valves.

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

[0070] A magnetic ring 28 and a magnetic field sensor 27 are installed on the threaded connector 25 and the threaded interface 26. The magnetic field sensor 27 is a miniature corrugated tube structure. When the medical staff unscrews the connector, the magnetic field sensor 27 senses the change in the magnetic field as the magnetic ring 28 moves away, thereby transmitting a signal to the controller 9. The controller 9 controls the reversing pump 24 to draw back the residual urine in the catheter 22 between the reversing pump 24 and the threaded interface 26 into the indwelling cavity 23, thereby preventing urine leakage when changing the urine collection bag 18 and realizing the automatic leakage prevention function of the catheter 22.

[0071] When catheter 22 becomes blocked, the reversing pump 24 first directs the flow in the forward direction. The flow rate and pressure during drainage are used to determine if a blockage has occurred. If the flow is obstructed and the pressure reaches a threshold, it indicates that catheter 22 is blocked. At this point, the controller 9 combines the pressure sensor signal on the protective sleeve 13 to comprehensively determine the type of blockage. Combining the flow rate and pressure in catheter 22 with the pressure sensor data, if the flow rate decreases and the pressure increases, and the pressure sensor detects a compressed state, it indicates that the catheter 22 is blocked due to compression from the patient's limb. The controller 9 controls the protective motor 15 and the plate motor 29 to adjust... The catheter 22 is guided and accommodated within the groove formed by the strip plate 20 to improve the compression state. If the pressure sensor does not detect a compressed state, it is because the catheter 22 is blocked due to foreign objects. In this case, the cleaning agent in the cleaning bottle 17, usually physiological saline, is pumped into the catheter 22 by the reversing pump 24. By continuously reversing and pumping the cleaning agent back and forth, pressure is applied to the blockage, flushing and clearing the blockage, and the catheter 22 is reopened. This eliminates the need for medical staff to manually open the catheter with a syringe, greatly reducing the efficiency of medical manpower and enhancing the flushing response speed of the blocked catheter 22, thus reducing the probability of serious consequences.
