Description

Technical Field

[0001] This utility model belongs to the field of postoperative care device technology, specifically relating to a cleaning device for postoperative care of anorectal surgery. Background Technology

[0002] After anorectal surgery, the wound is located at the exit of feces, making it very easy to get contaminated during defecation. The warm and humid environment can accelerate bacterial growth, causing infection, edema, or delayed healing, so cleaning and care are necessary.

[0003] Currently, a commonly used cleaning device in clinical and home care is the manual air-cushioned sitz bath device. For example, Chinese utility model patent document CN221357941U discloses a simple anal irrigation cup. In use, the patient places the cup on the ground or toilet seat, sits on the rim, and repeatedly squeezes the air cushion, causing the cleaning solution inside the cup to be sprayed out from the nozzle by the airflow, rinsing the perianal wound. During the rinsing process, fecal residue, secretions, blood, and other contaminants flushed from the wound flow back into the cup along with the cleaning solution, mixing with the remaining cleaning solution. When the patient continues to squeeze the air cushion, the liquid being drawn in or carried away is actually a contaminated mixture. Repeatedly rinsing the wound with this mixture not only fails to achieve effective cleaning but may also re-bring the contaminants to the wound, significantly increasing the risk of infection.

[0004] Therefore, there is an urgent need to provide a cleaning device that can achieve both clean and waste separation and avoid cross-contamination to solve the current technical problems. Summary of the Invention

[0025] like Figures 1 to 6 As shown, a cleaning device for postoperative care of anorectal surgery is disclosed, including a basin 1, an internal receiving groove 13, a backrest 11 fixedly mounted at the rear end of the basin 1, a water outlet 2 extending into the receiving groove 13 fixedly mounted on the backrest 11, and water outlet holes 21 evenly distributed on the water outlet 2; a water storage tank 3 fixedly mounted on the rear side of the backrest 11, an open-top water storage tank 6 disposed inside the water storage tank 3, a flexible hose 32 fixedly mounted on one side of the inside of the water storage tank 3, one end of the flexible hose 32 connected to the water outlet 2, and the other end of the flexible hose 32 extending to the bottom of the inside of the water storage tank 6; a detachable and sealed top cover 4 is provided on the top of the water storage tank 3; an air pumping mechanism 5 is provided on one side of the water storage tank 3 and connected thereto, the air pumping mechanism 5 being used to inject air into the inside of the water storage tank 3 to force the cleaning liquid inside the water storage tank 6 out from the water outlet 2.

[0026] Before use, the user opens the top cover 4 to remove the water tank 6, pours cleaning liquid into the water tank 6, puts it back into the water tank 3, and closes the top cover 4. The user sits on top of the basin 1 with the end of the water outlet 2 facing the area to be cleaned. Air is injected into the water tank 3 using the air pumping mechanism 5 to increase the air pressure inside the water tank 3. The top of the water tank 6 is open, and the high-pressure gas inside the water tank 3 acts directly on the liquid surface inside the water tank 6, forcing the cleaning liquid into the hose 32. The cleaning liquid flows through the hose 32 to the water outlet 2 and is sprayed out from the water outlet 21 to achieve cleaning. It enables seated cleaning, eliminating the need for bending over or assistance, making it convenient to use. The cleaning liquid is stored in the water tank 3, and wastewater is collected through the basin 1, achieving separation of clean and waste water and avoiding cross-contamination. The air pumping mechanism 5 injects air into the water tank 3, and the air pressure acts on the liquid surface in the water tank 6, forcing the cleaning liquid out from the water outlet 2 to form a cleaning water flow. The water tank 6 is independently set and has an open top for easy liquid addition and cleaning. The top cover 4 is removable and sealed to ensure the airtightness of the water tank 3 during air pumping. The hose 32 extends to the bottom of the water tank 6 to ensure that the liquid can be completely expelled, avoiding residue.

[0027] In some embodiments, such as Figure 1 , 4As shown in Figure 5, the air-inflating mechanism 5 includes an air-inflating chamber 51 fixedly disposed on one side of the water storage tank 3. The air-inflating chamber 51 is a cylindrical cavity whose bottom is connected to the water storage tank 3. A support cover 55 is provided on the top of the air-inflating chamber 51. A first air hole 551 communicating with the atmosphere is opened on the support cover 55. A guide rod 53 is slidably disposed on the support cover 55 along its axial direction. A piston plate 57 is slidably disposed inside the air-inflating chamber 51 at the lower end of the guide rod 53. The piston plate 57 is slidably and sealingly connected to the interior of the air-inflating chamber 51. A second air hole is opened on the piston plate 57. Hole 571; An elastic baffle 58 and a support plate 59 are provided below the piston plate 57. The middle part of the support plate 59 is fixedly connected to the piston plate 57, and a gap is left between the outer edge of the support plate 59 and the inner wall of the air chamber 51 for gas to pass through. The elastic baffle 58 is slidably disposed between the piston plate 57 and the support plate 59 along the axis of the piston plate 57, and is used to block the second air hole 571 when the piston plate 57 moves down. A swing arm 56 corresponding to the air chamber 51 is provided on one side of the basin 1. One end of the swing arm 56 is connected to the top end of the guide rod 53.

[0028] Specifically, the swing arm 56 drives the guide rod 53 and piston plate 57 to move upward. A negative pressure is created in the space below the piston plate 57, allowing outside air to sequentially enter the bottom of the air-pressuring chamber 51 and the water storage tank 3 through the first air hole 551, above the piston plate 57, the second air hole 571, above the support plate 59, and the gap along the outer edge of the support plate 59. The swing arm 56 then presses down, causing the piston plate 57 to move downward. The gas below the piston plate 57 is compressed, and the elastic baffle 58 is pressed shut, sealing the second air hole 571. The gas cannot return upward and can only enter the water storage tank 3 through the bottom of the air-pressuring chamber 51, thus achieving air inflation. The reciprocating motion of the manual swing arm 56 is converted into the up-and-down motion of the guide rod 53, which in turn drives the piston plate 57 to inflate the air, making operation effortless and ergonomic. The elastic baffle 58 and the second air hole 571 form a one-way valve, which, in conjunction with the gap along the outer edge of the support plate 59, enables air intake and compression when the piston plate 57 moves up and down, ensuring efficient air inflation. The swing arm 56 is located on one side of the pelvis 1, making it convenient for patients or caregivers to operate while seated.

[0029] In some embodiments, a support 54 is fixedly provided at the top end of the guide rod 53; the middle part of the swing arm 56 is rotatably connected to one side of the basin 1, and a connecting rod 52 is hinged to one end of the swing arm 56 near the air chamber 51. The end of the connecting rod 52 opposite to the swing arm 56 is rotatably connected to the support 54. The connecting rod 52 can compensate for movement deviation, avoid jamming, and improve service life. The swing arm 56 swings around the central fulcrum, and one end of it pushes the support 54 at the top end of the guide rod 53 through the connecting rod 52, causing the guide rod 53 to slide up and down axially.

[0030] In some embodiments, a handle 561 is provided at the end of the swing arm 56 opposite to the air chamber. The handle 561 is located at the end of the swing arm 56. According to the lever principle, the longer the lever arm, the less force is required to drive the air pump. The handle 561 provides a comfortable operating position, facilitates hand application of force, and prevents slippage.

[0031] In some embodiments, a connecting screw 591 is fixedly disposed at the center of the top of the support plate 59. The connecting screw 591 is fixedly connected to the middle of the piston plate 57, and an elastic baffle 58 is slidably fitted on the outside of the connecting screw 591. The center hole of the elastic baffle 58 is fitted onto the connecting screw 591, and it can only slide along the axial direction of the connecting screw 591 without radial displacement. When the piston plate 57 moves downward, the elastic baffle 58, under the guidance of air pressure and the connecting screw 591, flattens and presses against the lower surface of the piston plate 57, sealing the second air hole 571.

[0032] In some embodiments, such as Figure 3 As shown, a connecting hole 511 is provided on one side of the bottom of the air chamber 51, which is connected to the water storage tank 3. The compressed gas in the air chamber 51 enters the water storage tank 3 through the connecting hole 511, thereby realizing pressure transmission.

[0033] In some embodiments, such as Figure 6 As shown, a clearance groove 61 is provided on one side of the water storage tank 6. The clearance groove 61 provides structural clearance so that the water storage tank 6 can be smoothly installed into the water storage tank 3 without interfering with the hose 32. A carrying plate 62 is fixedly installed on the inner top of the water storage tank 6. The carrying plate 62 serves as a handle, making it convenient to lift the water storage tank 6 by hand for adding liquid or cleaning, thus avoiding contamination of the outside of the tank.

[0034] In some embodiments, a positioning ring 31 for positioning the water tank 6 is fixedly provided at the inner bottom of the water storage tank 3. The inside of the positioning ring 31 matches the shape of the bottom end of the water tank 6. The bottom end of the water tank 6 is inserted into the positioning ring 31 to form a fitting position, restricting horizontal movement.

[0035] In some embodiments, an inner pipe 111 is provided inside the backrest 11, the water outlet 2 is fixedly connected to one end of the inner pipe 111, and the hose 32 is fixedly connected to the other end of the inner pipe 111.

[0036] In some embodiments, a groove 12 is provided at the top front end of the basin 1 to facilitate the user's hand to reach in and assist in cleaning.
