Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and specifically relates to a dressing-changing device for anal care. Background Art

[0002] Perianal diseases often trouble patients due to their special onset location and nursing difficulty, causing great mental burden and physical pressure to patients. Postoperative nursing or daily cleaning and dressing change are important means to help the rapid recovery of perianal diseases.

[0003] A Chinese patent with the publication number CN115350353B discloses a dressing-changing and nursing device for cleaning the anus of perianal diseases. This dressing-changing and nursing device for cleaning the anus of perianal diseases and the nursing method use a flexible panel to make the limiting component contact with the patient's two buttocks, and under the action of the limiting component, the separated buttocks are in a fixed state, so as to facilitate the medical staff to observe and change the dressing of the patient's anal wound surface. The regulating component can control the medical hose to effectively clean the patient's wound surface, and at the same time, it can also control the dressing-changing mechanism to effectively change the dressing of the patient's anal wound surface, so as to achieve the purpose of improving the dressing-changing efficiency.

[0004] In the prior art, during the process of changing the dressing for a patient, due to the special position of the anus, it is easily squeezed by the gluteal muscles on both sides, resulting in poor visual exposure. Furthermore, during the actual operation, in order to facilitate the dressing-changing work on the wound surface, the medical staff needs the patient to cooperate to spread the gluteal muscles on both sides outward. However, in the actual operation, due to the special position, the patient will have a resistant psychology, which will cause the patient's nerves to be tense and the gluteal muscles to contract, affecting the normal progress of the dressing-changing work.

[0005] Therefore, the present invention provides a dressing-changing device for anal care. Summary of the Invention

Detailed implementation mode

[0034] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation modes.

[0035] As Figures 1 to 7 shown, a dressing change device for anal care described in an embodiment of the present invention includes a basin body 1, and also includes an automatic positioning component and an automatic cleaning component. The automatic positioning component and the automatic cleaning component are both arranged inside the basin body 1. The automatic positioning component includes an automatic telescopic rod 2, a lifting adjustment seat 3 and a hip fixing component 4. One end of the automatic telescopic rod 2 is fixedly connected to the bottom of the inner wall of the basin body 1, and the other end of the automatic telescopic rod 2 is fixedly connected to the bottom of the lifting adjustment seat 3. The number of the hip fixing components 4 is two and they are symmetrically arranged. The automatic positioning component drives the lifting adjustment seat 3 to move through the automatic telescopic rod 2. When the lifting adjustment seat 3 moves downward, the two hip fixing components 4 will be separated, thereby separating the patient's buttocks; when dressing change is required, the patient sits on the device in a sitting posture, and the patient's buttocks will be supported by the two hip fixing components 4. Then the automatic telescopic rod 2 will contract and drive the lifting adjustment seat 3 to descend. When the lifting adjustment seat 3 descends, the two hip fixing components 4 will open to both sides. When the hip fixing components 4 open, the patient's buttocks will be pried open, so that the patient's wound is exposed. Then, under the action of the automatic cleaning component, the patient's wound is rinsed. By controlling the descending distance of the lifting adjustment seat 3, the opening distance of the hip fixing components 4 can be controlled, which is convenient for patients in different situations. The cleaning work during dressing change can be carried out automatically without too much operation by medical staff, so that the patient's wound does not need to be directly exposed in the field of vision of medical staff, better taking care of the patient's emotions and being beneficial to the patient's recovery.

[0036] As Figures 1 to 7As shown, the automatic positioning component further includes a vertical plate 5 fixedly installed at the bottom of the inner wall of the basin body 1. A positioning seat 6 is fixedly installed at the top of the vertical plate 5. Rotating plates 7 are symmetrically and rotatably installed on the inner wall of the positioning seat 6. Two hip fixing components 4 are respectively arranged on the tops of the two rotating plates 7. The lifting and adjusting seat 3 is slidably arranged between the two rotating plates 7. An annular shaft 8 is fixedly installed on the outer wall of the positioning seat 6. The outer wall of the annular shaft 8 is slidably connected to the inner wall of the rotating plate 7. Elastic members 9 are symmetrically sleeved on the outer wall of the annular shaft 8. The two ends of the two elastic members 9 are respectively fixedly connected to the outer walls of the positioning seat 6 and the two rotating plates 7. During operation, the patient sits on the top of the device with the hips placed on the two hip fixing components 4. Then, the automatic telescopic rod 2 contracts. When the automatic telescopic rod 2 contracts, it drives the lifting and adjusting seat 3 to move downward. When the lifting and adjusting seat 3 moves downward, it squeezes the two rotating plates 7, causing the two rotating plates 7 to rotate to both sides. When the rotating plates 7 rotate, they drive the two hip fixing components 4 to open to both sides. When the hip fixing components 4 open, the patient's hips will open, exposing the wound on the patient's hips. Then, the automatic cleaning component sprays the cleaning liquid onto the patient's wound to rinse the patient's wound, achieving the effect of automatic cleaning. When the device finishes working, the automatic telescopic rod 2 extends to raise the lifting and adjusting seat 3. The rotating plates 7 will rotate in the reverse direction under the action of the reverse elastic force of the elastic members 9, causing the two hip fixing components 4 to reset.

[0037] As Figures 4 to 6As shown, the hip fixing assembly 4 includes a rotation adjustment block 401, which is rotatably installed on the inner wall of the rotating plate 7. A tightening and positioning member 402 is rotatably installed on the inner wall of the rotation adjustment block 401. The outer wall of the tightening and positioning member 402 is threadedly connected to the inner wall of the rotating plate 7. An elastic metal cushion plate 403 is arranged above the rotation adjustment block 401. An adjustment screw 404 is rotatably installed at the bottom of the elastic metal cushion plate 403. The outer wall of the adjustment screw 404 is threadedly connected to the inner wall of the rotation adjustment block 401. One end of the adjustment screw 404 away from the elastic metal cushion plate 403 is fixedly installed with an adjustment knob 405. Support plates 406 are symmetrically and fixedly installed at the top of the rotation adjustment block 401. The outer wall of the support plate 406 abuts against the elastic metal cushion plate 403. A flexible pad 407 is fixedly installed at the top of the elastic metal cushion plate 403; Before the device is used, rotate the tightening and positioning member 402 to release the fixation of the rotation adjustment block 401, and then rotate the rotation adjustment block 401 to adjust the angle of the flexible pad 407. When the angle of the flexible pad 407 is adjusted, rotate the tightening and positioning member 402 in the reverse direction again to fix the rotation adjustment block 401 again. Rotate the adjustment knob 405 to drive the adjustment screw 404 to rotate. When the adjustment screw 404 rotates, the position of its end will change. When the position of the end of the adjustment screw 404 changes, it will change the pulling degree on the elastic metal cushion plate 403, and in cooperation with the support plate 406, it will change the bending degree of the elastic metal cushion plate 403, thereby achieving the effect of adjusting the bending degree of the flexible pad 407. By changing the angle and bending degree of the flexible pad 407, the device can fit patients with different body types.

[0038] As Figures 1 to 8 shown, the automatic cleaning assembly includes a water pump 10 and a spray head 11. The water pump 10 is fixedly installed at the bottom of the inner wall of the basin body 1. The automatic cleaning assembly conveys the cleaning liquid to the spray head 11 through the water pump 10 and sprays it out through the spray head 11. The sprayed cleaning liquid will clean the wound of the patient; When the patient's hip is fixed by the automatic positioning assembly, the water pump 10 starts to work. Under the action of the water pump 10, the cleaning liquid is sprayed out through the spray head 11, and the sprayed cleaning liquid will wash the wound of the patient, thereby achieving the effect of automatic cleaning.

[0039] As Figures 1 to 8As shown in the figure, the automatic cleaning component further includes a water delivery pipe 12. One end of the water delivery pipe 12 is fixedly connected to the inner wall of the water pump 10. A connecting hose 13 is communicated with the end of the water delivery pipe 12 far away from the water pump 10. The end of the connecting hose 13 far away from the water delivery pipe 12 is communicated with the spray head 11. One end of the spray head 11 is fixedly installed with a hinge seat 14. A control valve 15 is fixedly installed on the outer wall of the water delivery pipe 12. When performing the cleaning work, under the action of the water pump 10, the cleaning liquid is conveyed into the interior of the water delivery pipe 12. After the cleaning liquid enters the water delivery pipe 12, it will flow along the water delivery pipe 12 into the connecting hose 13. Then, under the action of the connecting hose 13, the cleaning liquid enters the spray head 11. Finally, under the action of the spray head 11, the cleaning liquid is sprayed out for cleaning work. The spray head 11 can rotate under the action of the hinge seat 14 and the connecting hose 13, so as to adjust the angle of the spray head 11. By adjusting the angle, it can adapt to patients of different body types.

[0040] As Figures 1 to 9 shown, symmetrically fixed on the bottom of the inner wall of the basin body 1 are heating plates 16. Fixed on the top of the basin body 1 is a seat cushion 17. Fixed on the inner wall of the seat cushion 17 is a heating pipe 18. One end of the heating pipe 18 is fixedly connected to the inner wall of the water pump 10. Before using the device, start the heating plate 16. The heating plate 16 converts electrical energy into heat energy to heat the cleaning liquid. Under the action of the heating plate 16, the temperature of the cleaning liquid is adjusted, so as to increase the comfort of the patient during the cleaning work. After the cleaning liquid is heated, start the water pump 10 to work. At this time, the control valve 15 is in a closed state. Under the action of the water pump 10, the heated cleaning liquid enters from one end of the heating pipe 18. The cleaning liquid entering the heating pipe 18 will flow back from the other end of the heating pipe 18, so that the heated cleaning liquid circulates. Since the middle part of the heating pipe 18 is installed inside the seat cushion 17, the cleaning liquid heats the seat cushion 17. When the patient changes dressings, he will sit on the seat cushion 17. By heating the seat cushion 17, the comfort of the patient when using the device in a low-temperature environment is increased.

[0041] As Figures 1 to 7 shown, fixed on the inner wall of the basin body 1 is a partition plate 19. The interior of the basin body 1 forms a liquid medicine chamber and a waste liquid chamber through the partition plate 19. Both the water pump 10 and the heating plate 16 are located inside the liquid medicine chamber. The water delivery pipe 12 penetrates through the partition plate 19. The end of the heating pipe 18 far away from the water pump 10 penetrates through the partition plate 19 and extends into the interior of the liquid medicine chamber. By the partition plate 19, the space inside the basin body 1 is divided into a liquid medicine chamber and a waste liquid chamber, separating the cleaning liquid before and after use to avoid cross-infection and ensure the effectiveness of the cleaning work. The clean cleaning liquid is located in the liquid medicine chamber. The water pump 10 conveys the cleaning liquid in the liquid medicine chamber for cleaning work. The waste liquid after cleaning the patient will fall into the waste liquid chamber for collection for subsequent treatment.

[0042] As Figures 1 to 11As shown, a lifting plate 20 is slidably installed on the inner wall of the partition plate 19. One end of the lifting plate 20 is lapped on the top of the lifting adjustment seat 3. A hook plate 21 is fixedly installed at the end of the lifting plate 20 away from the lifting adjustment seat 3. A rotating seat 22 is fixedly installed on the inner wall of the liquid medicine chamber. A stirring frame 23 is rotatably installed in the inner wall of the rotating seat 22. A number of stirring rods 24 are fixedly installed on the inner wall of the stirring frame 23. A receiving block 25 is fixedly installed at one end of the stirring frame 23. The receiving block 25 is lapped on the top of the hook plate 21. A connecting rope 26 is fixedly installed between the outer walls of the hook plate 21 and the receiving block 25. When preparing for the use of the device, water and medicine are put into the liquid medicine chamber. Then, the automatic telescopic rod 2 is started. After the automatic telescopic rod 2 is started, it will first extend and then contract and repeat the cycle. When the automatic telescopic rod 2 extends, the lifting adjustment seat 3 will move upward. When the lifting adjustment seat 3 moves upward, it will drive the lifting plate 20 to move upward. When the lifting plate 20 moves upward, it will drive the hook plate 21 to move upward. When the hook plate 21 moves upward, it will hook the receiving block 25, so that the receiving block 25 drives the stirring frame 23 to rotate. When the automatic telescopic rod 2 contracts, the hook plate 21 will descend. When the hook plate 21 descends, it will pull the stirring frame 23 to rotate in the reverse direction and reset under the action of the connecting rope 26. When the stirring frame 23 rotates back and forth, it will drive the stirring rods 24 to rotate accordingly, so as to stir the water and medicine, make the water and medicine mix quickly and evenly, ensure the cleaning effect of the device, and at the same time, under the stirring of the stirring rods 24, the cleaning liquid can be heated more evenly, improving the use effect of the device.

[0043] As Figures 1 to 11 shown, a rotating shaft 27 is rotatably installed on the inner wall of the stirring frame 23. A gear 28 is fixedly installed at one end of the rotating shaft 27. A toothed ring 29 is fixedly installed on the inner wall of the liquid medicine chamber. The teeth of the toothed ring 29 are meshed with the teeth of the gear 28. A stirring plate 30 is fixedly installed on the outer wall of the rotating shaft 27 and inside the stirring frame 23. When the stirring frame 23 rotates back and forth, it will drive the rotating shaft 27 to rotate. When the rotating shaft 27 rotates, it will drive the gear 28 to rotate. Since the gear 28 and the toothed ring 29 are in a meshed state, when the gear 28 rotates, it will drive the rotating shaft 27 to rotate automatically. When the rotating shaft 27 rotates, it will drive the stirring plate 30 to rotate. By the rotation of the stirring plate 30, the stirring effect of the device is further improved, so that the cleaning liquid can play a full role.

[0044] As Figures 1 to 3As shown in the figure, a liquid medicine adding tube 31 and a liquid medicine replacing tube 32 are fixedly installed on one inner wall of the liquid medicine cavity of the basin body 1. A waste liquid discharging tube 33 is fixedly installed on one inner wall of the waste liquid cavity of the basin body 1. Sealing caps 34 are threadedly installed at one ends of the waste liquid discharging tube 33, the liquid medicine replacing tube 32 and the liquid medicine adding tube 31. Supports 35 are symmetrically and fixedly installed on the outer wall of the basin body 1. Support legs 36 are symmetrically and fixedly installed at the bottom of the supports 35. When adding water and medicine, open the sealing cap 34 on the liquid medicine adding tube 31, and then add water and medicine into the liquid medicine cavity of the device through the liquid medicine adding tube 31 to complete the adding work. When it is necessary to replace the cleaning liquid, open the sealing cap 34 on the liquid medicine replacing tube 32 to discharge the cleaning liquid. Similarly, when it is necessary to treat the waste liquid, open the sealing cap 34 on the waste liquid discharging tube 33. Connect the support legs 36 to the basin body 1 through the supports 35, and support the basin body 1 through the support legs 36 to make the basin body 1 at a proper height, so as to facilitate the use of the device.

[0045] Working principle: When dressing change is required, the patient sits above the device in a sitting position. The patient's buttocks are supported by two buttock fixing components 4. Then, the automatic telescopic rod 2 contracts to drive the lifting and adjusting seat 3 to descend. When the lifting and adjusting seat 3 moves downward, it squeezes the two rotating plates 7, causing the two rotating plates 7 to rotate to both sides. When the rotating plates 7 rotate, they drive the two buttock fixing components 4 to open to both sides. When the buttock fixing components 4 open, the patient's buttocks open, exposing the wound on the patient's buttocks. Then, the automatic cleaning component sprays the cleaning liquid onto the patient's wound to wash the patient's wound, achieving the effect of automatic cleaning. By controlling the descending distance of the lifting and adjusting seat 3, the opening distance of the buttock fixing components 4 can be controlled, facilitating the application to patients in different situations. The cleaning work during dressing change can be carried out automatically without excessive operation by medical staff. Thus, the patient's wound does not need to be directly exposed to the view of medical staff, better taking care of the patient's emotions and being beneficial to the patient's recovery. When the device finishes working, the automatic telescopic rod 2 extends to raise the lifting and adjusting seat 3. The rotating plates 7 will rotate in the reverse direction under the reverse elastic force of the elastic member 9, causing the two buttock fixing components 4 to reset. When the buttock fixing components 4 need to be adjusted, the rotation fixing member 402 is rotated to release the fixation of the rotation adjustment block 401. Then, by rotating the rotation adjustment block 401, the angle of the flexible pad 407 is adjusted. After the angle of the flexible pad 407 is adjusted, the rotation fixing member 402 is rotated in the reverse direction again to fix the rotation adjustment block 401 again. The rotation adjustment knob 405 drives the adjustment screw 404 to rotate. When the adjustment screw 404 rotates, the position of its end changes. When the position of the end of the adjustment screw 404 changes, the pulling degree on the elastic metal backing plate 403 is changed. In cooperation with the support plate 406, the bending degree of the elastic metal backing plate 403 is changed, thereby achieving the effect of adjusting the bending degree of the flexible pad 407. By changing the angle and bending degree of the flexible pad 407, the device can fit patients of different body types.

[0046] After the patient's buttocks are fixed by the automatic positioning component, under the action of the water pump 10, the cleaning liquid is transported into the interior of the water delivery pipe 12. After the cleaning liquid enters the water delivery pipe 12, it will flow along the water delivery pipe 12 into the connecting hose 13. Then, under the action of the connecting hose 13, the cleaning liquid enters the nozzle 11. Finally, under the action of the nozzle 11, the cleaning liquid is sprayed out for cleaning work. The nozzle 11 can rotate under the action of the hinge seat 14 and the connecting hose 13, thereby adjusting the angle of the nozzle 11. By adjusting the angle, it can adapt to patients of different body types.

[0047] Before using the device, start the heating plate 16, which converts electrical energy into thermal energy to heat the cleaning liquid. The temperature of the cleaning liquid is adjusted under the action of the heating plate 16, thereby increasing the comfort of the patient during cleaning. After the cleaning liquid is heated, start the water pump 10 to work. At this time, the control valve 15 is in a closed state. Under the action of the water pump 10, the heated cleaning liquid enters from one end of the heating tube 18, and the cleaning liquid entering the heating tube 18 will flow back from the other end of the heating tube 18, thereby allowing the heated cleaning liquid to circulate. Since the middle part of the heating tube 18 is installed on the inner side of the seat cushion 17, the cleaning liquid heats the seat cushion 17. The patient will sit on the seat cushion 17 when changing the dressing. By heating the seat cushion 17, the comfort of the patient when using the device in a low temperature environment is increased.

[0048] When preparing the device before use, water and medicine are put into the medicine liquid chamber, and then the automatic telescopic rod 2 is started. After the automatic telescopic rod 2 is started, it will first extend and then contract and repeat the cycle. When the automatic telescopic rod 2 is extended, the lifting and adjusting seat 3 will move upward, and when the lifting and adjusting seat 3 moves upward, it will drive the lifting plate 20 to move upward, and when the lifting plate 20 moves upward, it will drive the hook plate 21 to move upward. When the hook plate 21 moves upward, it will hook the receiving block 25, so that the receiving block 25 drives the stirring frame 23 to rotate. When the automatic telescopic rod 2 contracts, the hook plate 21 will drop. When the hook plate 21 drops, it will pull the stirring frame 23 to rotate in the opposite direction under the action of the connecting rope 26 and then reset. When the stirring frame 23 rotates back and forth, it will drive the stirring rod 24 to rotate accordingly, thereby stirring the water and the medicine, so that the water and the medicine can be mixed quickly and evenly, ensuring the cleaning effect of the device. At the same time, under the stirring of the stirring rod 24, the cleaning liquid can be heated more evenly, thereby improving the use effect of the device. When the stirring frame 23 rotates back and forth, it will drive the rotating shaft 27 to rotate, and when the rotating shaft 27 rotates, it will drive the gear 28 to rotate. Since the gear 28 and the gear ring 29 are in a meshing state, when the gear 28 rotates, it will drive the rotating shaft 27 to rotate automatically. When the rotating shaft 27 rotates, it will drive the stirring plate 30 to rotate. The rotation of the stirring plate 30 further improves the stirring effect of the device, so that the cleaning liquid can be fully utilized.
