Description

Technical Field

[0001] This invention relates to the field of nursing assistance technology, specifically to an auxiliary device for perianal care. Background Technology

[0002] Common conditions that damage the intestines and anus include hemorrhoids, anal fissures, and anal fistulas. When people have anal conditions, they need to receive medical treatment and follow up with post-treatment care to restore and care for the wounds around the anus and intestines, relieve pain, and promote wound healing. Chinese patent discloses a nursing device for elderly care of anal incontinence, application number CN202322118830.1. The device controls the saline pressure by adjusting the saline output of a micro pump to the required saline pressure. The nozzle is then moved to the anus of the elderly person and then stopped. The elderly person can feel the saline spraying onto the anus. The device is then limited by a limiting component inside the slide rail or by the nurse holding it still, and the anus of the elderly person is then cleaned. However, current nursing procedures require different medications and tools for wounds and treatments. Medical staff have to search for and retrieve these items when performing nursing procedures, which is extremely inconvenient and can easily lead to cross-contamination and infection. Therefore, this invention provides an auxiliary device for perianal care to meet people's needs. Summary of the Invention

[0003] This invention provides an auxiliary device for perianal care, which can effectively solve the problem mentioned in the background art that different medicines and tools are needed for wounds and treatments, and that medical staff have to search for and retrieve these items when performing care operations, which is extremely inconvenient and can easily cause cross-contamination and infection between items.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary device for perianal care, comprising a movable base, wherein movable wheels are installed at the four corners of the bottom of the movable base, and a contamination-proof delivery mechanism is installed at one end of the top of the movable base; The pollution-proof delivery mechanism includes a support base; A support base is installed at one end of the top of the mobile base. A circular hollow storage frame is installed at the top of the support base. A rotating and repositioning circular frame is movably installed inside the circular hollow storage frame. A rotating circular rod is installed in the middle of the rotating and repositioning circular frame. Storage cavities are equidistantly opened along the circumferential direction on the edge of the rotating and repositioning circular frame. An item storage frame is installed at one end of the inside of the storage cavity. A rotary motor is installed in the middle of the back of the circular hollow storage frame, and a guide plate is installed at the top of the back of the circular hollow storage frame. An L-shaped movable seat is movably engaged in the middle of the guide plate. An electric push rod is installed at one end of the L-shaped movable seat, and a delivery push block is connected to the end of the electric push rod. Operating notches are symmetrically opened at both ends of the top of the circular hollow storage frame.

[0005] According to the above technical solution, the edge of the rotating transposition circular frame is in contact with the inner wall of the circular hollow storage frame, and one end of the rotating circular rod is connected to the output shaft of the rotating motor. The delivery pusher has the same shape as the operating notch, and the delivery pusher and the operating notch are positioned corresponding to each other.

[0006] According to the above technical solution, a splicing adsorption block is installed inside the storage cavity at one side of the item storage frame, a positioning shaft is installed in the middle of the splicing adsorption block, and an unbalanced counterweight is installed at one end of the bottom of the item storage frame. An electromagnet is installed at the middle of one end of the delivery pusher, and an adsorption metal block is embedded at the middle of one end of the splicing adsorption block.

[0007] According to the above technical solution, the end of the positioning shaft is rotatably connected to the middle of the item storage frame, the surface of the adsorption metal block is flush with the end of the splicing adsorption block, and the electromagnet corresponds to the middle position of the operating notch.

[0008] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use. 1. Equipped with a contamination-preventing delivery mechanism, this device utilizes a rotating transposition frame and a storage box to facilitate the categorization and sequential storage of medicines and tools used during the nursing process. A drive motor and rotating rod work together to rotate the transposition frame, causing the storage boxes to move sequentially to the operating notch. An electric push rod can adjust the position of the corresponding storage box, allowing it to be moved out of the circular hollow storage box. This greatly facilitates staff in retrieving items and performing nursing care, preventing the accumulation of items that would require staff to search for them. Furthermore, the electric push rods sequentially push out the storage boxes of items in order, which provides a certain degree of assistance and reminder for the staff to perform nursing operations. This allows the staff to perform nursing operations in the order in which the items are pushed out, avoiding errors that could affect the normal wound healing effect and reducing the chance of errors. Even nursing staff who are not familiar with the operating procedures can operate accurately and smoothly.

[0009] 2. By using the unbalanced counterweight bar and the positioning shaft in combination, the storage box can automatically flip downward after extending from the operating notch, so that the stored items can slide down automatically, making it more convenient and faster for staff to retrieve them; At the same time, by using electromagnets and adsorption metal blocks in combination, the delivery pusher and the item storage box that have been moved to the operation gap position can be attracted and fixed to each other, thereby realizing the pushing of the item storage box to deliver items and pulling it back to its original position, making operation and control more convenient.

[0010] 3. The inclined receiving frame provides a temporary storage platform for slipped items, making it convenient for staff to pick them up directly. This reduces the chance of staff's hands coming into contact with other items during handling, preventing contamination. The electric telescopic rod adjusts the position of the arc-shaped fitting and resetting block, which fits against the bottom of the item storage frame. The item storage frame is then adjusted and reset to the angle corresponding to the operating notch, so that it can be smoothly returned to the circular hollow storage frame through the operating notch later.

[0011] 4. By using the inclined foot pedal and traction rope in combination, the positions of the movable round rod and L-shaped moving seat can be adjusted. This allows for easy adjustment of the starting position of the electric push rod according to different needs of storing and delivering items. When delivering items, the electric push rod can push the item storage box out completely from the operating notch, allowing it to smoothly deflect around the positioning axis to deliver the item. When storing items, the starting position of the electric push rod is further away from the operating notch, so that only part of the item storage box extends out of the operating notch when pushed, preventing the item storage box from extending completely and deflecting, which would make it inconvenient to place items.

[0012] 5. It is equipped with an auxiliary support and protection mechanism. The drive motor and vertical rotating screw work together to facilitate the adjustment of the height of the lifting frame and support frame. The patient's lower limbs correspond to the lower limb arc positioning groove, so that the patient's anus can be exposed by pushing the patient's lower limbs upward. There is no need for the patient to lift the lower limbs themselves or for medical staff to lift them up. It is more labor-saving and quick to use, and provides great convenience for caring for paralyzed or elderly patients. Suitable for patients in a supine position, the anus is easily visible to medical staff, providing a better field of vision and reducing unnecessary operations for medical staff during care.

[0013] 6. The mobile flatbed can move along the guide strip to easily insert the inclined sponge lumbar support pad into the lower back of the patient when the patient is raised, providing support and protection for the lumbar region of the patient in a supine position, so that the patient can maintain the posture more easily and stably during care. At the same time, the adjusting stud and L-shaped positioning block work together to facilitate the adjustment of the position of the silicone soft block, so that it fits tightly between the patient's anus and waist during adjustment. This intercepts and isolates the liquid medications used for anal care, preventing them from sliding down the patient's skin and dripping everywhere, causing dirt and mess to the patient's skin and the surrounding environment.

[0014] 7. By using a water pump and an axial flow fan in conjunction, disinfectant liquid and gas are sequentially delivered to the atomizing cleaning nozzle and gas distribution box through the drain pipe and exhaust pipe, respectively. This sterilizes and cleans the silicone soft block and the inclined receiving frame, and dries them with air. No manual disinfection and cleaning is required, which improves work efficiency. Moreover, cleaning can be performed directly after the nursing care is completed, which is convenient for the subsequent nursing care of the next patient and reduces the chance of cross-infection between items used by patients. Meanwhile, the connecting frame and positioning plate can rotate around the positioning cylinder to adjust the position of the positioning plate, preventing the positioning plate and connecting frame from obstructing the nursing operations of medical staff during the nursing process. The height of the two positioning plates is matched with the height of the inclined receiving frame and the attached silicone soft block, so that the connecting frame can smoothly reach the corresponding cleaning position after rotation. The operation and use are simple.

[0015] In summary, by combining a contamination-preventing delivery mechanism with an auxiliary support and protection mechanism, the overall nursing process is facilitated from two aspects: delivering nursing supplies and providing support and protection for the patient's body. This reduces manual operations for medical staff, making nursing procedures more convenient and reducing the chance of errors. Furthermore, automated delivery of items reduces cross-infection caused by handling items, improving the safety of nursing care. The interception and protection of the area below the patient's anus, where liquid medications are prone to slipping, also reduces the chance of infection from dripping medications. Afterward, thorough disinfection and cleaning of easily accessible areas are carried out to maintain the cleanliness of the equipment. Attached Figure Description

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] Example: Figure 1-9 As shown, the present invention provides a technical solution, an auxiliary device for perianal care, including a movable base 1, with movable wheels 2 installed at the four corners of the bottom of the movable base 1, and a contamination-proof delivery mechanism 3 installed at one end of the top of the movable base 1. The anti-pollution delivery mechanism 3 includes a support base 301, a circular hollow storage frame 302, a rotating and shifting circular frame 303, a rotating circular rod 304, a storage cavity 305, a splicing adsorption block 306, a positioning shaft 307, an item storage frame 308, an unbalanced counterweight bar 309, a rotary motor 310, a guide plate 311, an L-shaped moving seat 312, an electric push rod 313, a delivery push block 314, an electromagnet 315, an adsorption metal block 316, an operating notch 317, an inclined receiving frame 318, a waste discharge notch 319, an electric telescopic rod 320, an arc-shaped fitting and resetting block 321, a movable circular rod 322, a compression spring 323, an extension plate 324, a guide post 325, a guide frame 326, a connecting frame 327, a resetting spring 328, an inclined foot pedal 329, and a traction rope 330. A support base 301 is installed at one end of the top of the mobile base 1. A circular hollow storage frame 302 is installed at the top of the support base 301. A rotating and repositioning circular frame 303 is movably installed inside the circular hollow storage frame 302. A rotating circular rod 304 is installed in the middle of the rotating and repositioning circular frame 303. Storage cavities 305 are equidistantly opened along the circumferential direction on the edge of the rotating and repositioning circular frame 303. An item storage frame 308 is installed at one end inside the storage cavity 305. A rotary motor 310 is installed in the middle of the back of the circular hollow storage frame 302. The edge of the rotating and shifting circular frame 303 fits against the inner wall of the circular hollow storage frame 302. One end of the rotating rod 304 is connected to the output shaft of the rotary motor 310. A guide plate 311 is installed on the top of the back of the circular hollow storage frame 302. An L-shaped movable seat 312 is movably engaged in the middle of the guide plate 311. An electric push rod 313 is installed at one end of the L-shaped movable seat 312. A delivery push block 314 is connected to the end of the electric push rod 313. Operation notches 317 are symmetrically opened at both ends of the top of the circular hollow storage frame 302. The delivery push block 314 has the same shape as the operation notch 317. The positions of 317 correspond to each other. The rotating and shifting circular frame 303 and the item storage frame 308 work together to facilitate the classification and storage of medicines and tools used in the nursing process, and to store them in order. After the rotary motor 310 and the rotating rod 304 are used together, the rotating and shifting circular frame 303 is rotated, so that the item storage frames 308 are moved to the operation notch 317 in the installation order. The electric push rod 313 can adjust the position of the corresponding item storage frame 308, so that it can be moved out of the circular hollow storage frame 302. This provides great convenience for staff to retrieve items and perform nursing care, and prevents items from piling up and causing staff to have to search for them when they need to use them. Furthermore, the electric push rod 313 sequentially pushes out the item storage box 308 in order, which provides a certain auxiliary reminder for the staff's nursing operation. This allows the staff to perform the nursing operation in the order in which the items are pushed out, avoiding staff errors that could affect the normal wound healing effect and reducing the chance of errors. Even nursing staff who are not familiar with the operating procedures can operate accurately and smoothly. Inside the storage cavity 305, a splicing adsorption block 306 is installed on one side of the item storage frame 308. A positioning shaft 307 is installed in the middle of the splicing adsorption block 306. The end of the positioning shaft 307 is rotatably connected to the middle of the item storage frame 308. An unbalanced counterweight bar 309 is installed at one end of the bottom of the item storage frame 308. An electromagnet 315 is installed in the middle of one end of the delivery push block 314, and an adsorption metal block 316 is embedded in the middle of one end of the splicing adsorption block 306. The surface of the adsorption metal block 316 is flush with the end of the splicing adsorption block 306. The electromagnet 315 corresponds to the middle position of the operation notch 317. The unbalanced counterweight bar 309 and the positioning shaft 307 cooperate with each other. After the item storage frame 308 extends out of the operation notch 317, it can automatically flip downward, so that the stored items can slide down automatically, making it more convenient and faster for staff to take them out. At the same time, the electromagnet 315 and the adsorption metal block 316 cooperate with each other so that the delivery push block 314 and the item storage box 308 moved to the operation notch 317 can be attracted and fixed to each other, thereby realizing the push of the item storage box 308 to deliver items and the pull of it back to the original position, making operation and control more convenient. A tilted receiving frame 318 is installed at the center of one end of a circular hollow storage frame 302. A waste discharge notch 319 is opened at the center of one end of the tilted receiving frame 318. An electric telescopic rod 320 is installed at an angle inside one end of the tilted receiving frame 318. An arc-shaped fitting and resetting block 321 is connected to the end of the electric telescopic rod 320. The center of the tilted receiving frame 318 and the center of the operating notch 317 are located on the same vertical plane. The arc-shaped fitting and resetting block 321 faces the center of the bottom of the operating notch 317. The tilted receiving frame 318 is used for delivery and sliding. The items are provided with a temporary storage platform, which makes it convenient for staff to directly access them, reducing the chance of staff's hands coming into contact with other items during care, preventing contamination. The electric telescopic rod 320 adjusts the position of the arc-shaped fitting and reset block 321, and uses the arc-shaped fitting and reset block 321 to fit with the bottom of the item storage frame 308, and adjusts and resets the item storage frame 308 to return it to the angle corresponding to the operating notch 317, so that it can be smoothly returned to the circular hollow storage frame 302 from the operating notch 317 later. A movable round rod 322 is installed through the middle of one end of the guide plate 311. A compression spring 323 is sleeved on the surface of the movable round rod 322. An extension plate 324 is connected to one end of the bottom of the guide plate 311. A guide post 325 is installed in the middle of one end of the extension plate 324. Guide frames 326 are symmetrically installed at the top of the movable base 1 below the circular hollow storage frame 302. A connecting frame 327 is connected to the inner side of one end of the movable base 1. Return springs 328 are symmetrically installed inside the connecting frame 327. An inclined foot pedal 329 is movably installed on the top of the connecting frame 327. A traction rope 330 is connected to the top end of the inclined foot pedal 329. The traction rope 330 is sequentially pressed against the top surface of one guide frame 326, the bottom surface of another guide frame 326, and the surface of the guide post 325. One end of 30 is connected to one end of the movable round rod 322, and one end of the movable round rod 322 is connected to the L-shaped movable seat 312. By using the inclined pedal 329 and the traction rope 330 in cooperation, the positions of the movable round rod 322 and the L-shaped movable seat 312 can be adjusted. This allows the starting position of the electric push rod 313 to be adjusted according to different needs of storing and delivering items. When delivering items, the electric push rod 313 can push the item storage box 308 out of the operating notch 317 completely, so that it can smoothly deflect around the positioning axis 307 to deliver items. When storing items, the starting position of the electric push rod 313 is further away from the operating notch 317, so that when the item storage box 308 is pushed, only part of it extends out of the operating notch 317, preventing the item storage box 308 from extending out completely and deflecting, which would make it inconvenient to place items. The top of the mobile base 1 is equipped with an auxiliary support and protection mechanism 4; The auxiliary support and protection mechanism 4 includes a fixed long frame 401, a drive motor 402, a guide vertical frame 403, a vertical rotating screw 404, a drive sprocket 405, a transmission chain 406, a lifting guide block 407, a lifting frame 408, a support frame 409, a lower limb arc-shaped positioning groove 410, an elastic strap 411, a guide strip 412, a moving plate 413, an inclined sponge waist protection pad 414, a splicing moving frame 415, and an L-shaped positioning device.

A drive motor 402 is installed at one end inside the fixed long frame 401. Guide vertical frames 403 are symmetrically installed at both ends of the top of the fixed long frame 401. A vertical rotating screw 404 is rotatably installed in the middle of each of the two guide vertical frames 403. A drive sprocket 405 is connected to the bottom of each of the two vertical rotating screws 404. A transmission chain 406 is sleeved between the surfaces of the two drive sprockets 405. The output shaft of the drive motor 402 is connected to the middle of one of the drive sprockets 405. The drive sprocket 405 and the transmission chain 406 are both located inside the fixed long frame 401. The two vertical rotating screws 404 are respectively movably inserted through two lifting guide blocks 407. The vertical rotating screws 404 and the lifting guide blocks 407 are connected by threads. The two guide frames 403 are each movably connected to a lifting guide block 407. One end of the lifting guide block 407 is connected to a lifting frame 408. The top of the lifting frame 408 is connected to a support frame 409. The top of the support frame 409 has symmetrical lower limb arc-shaped positioning grooves 410 at both ends. An elastic strap 411 is installed on the top of the support frame 409 on one side of the lower limb arc-shaped positioning groove 410. The drive motor 402 and the vertical rotating screw 404 work together to facilitate the adjustment of the height of the lifting frame 408 and the support frame 409. The patient's lower limb corresponds to the lower limb arc-shaped positioning groove 410, so that the patient's anus can be exposed by pushing the patient's lower limb upward. The patient does not need to lift the lower limb by himself or the medical staff need to lift it. It is more labor-saving and quick to use, which provides great convenience for the care of paralyzed or weak patients or the elderly. It is suitable for patients in a supine position. The anus can be easily displayed in front of the medical staff, which provides a better field of vision during care and reduces the unnecessary operation of the medical staff during care. A guide strip 412 is symmetrically installed in the middle of the support frame 409. A movable plate 413 is movably installed in the middle of the support frame 409. An inclined sponge waist protection pad 414 is installed at the top of the movable plate 413. One end of the movable plate 413 is connected to a splicing movable frame 415. An L-shaped positioning block 416 is installed in the middle of the splicing movable frame 415. An adjusting stud 417 is installed through the middle of the L-shaped positioning block 416. A silicone soft block 418 is rotatably connected to the top of the adjusting stud 417. Guide grooves are symmetrically opened at the bottom of the movable plate 413 and the bottom of the splicing movable frame 415. The locking strip 412 is movably engaged inside the guide groove. The adjusting stud 417 and the L-shaped positioning block 416 are connected by threads. The bottom end of the silicone soft block 418 is provided with a circular slot. The top end of the adjusting stud 417 is rotated and engaged inside the circular slot. The angle between the bottom end of the splicing moving frame 415 and the horizontal plane is 2 degrees. The moving plate 413 can move forward along the guide strip 412, which makes it easy to insert the inclined sponge waist protection pad 414 into the lower back of the patient when the patient is raised, so as to support and protect the waist of the patient in the supine position, so that the patient can maintain the posture more easily and stably during care. At the same time, the adjusting stud 417 and the L-shaped positioning block 416 work together to make it easy to adjust the position of the silicone soft block 418 so that it fits tightly between the patient's anus and waist during adjustment. This intercepts and isolates the liquid medication used for anal care, preventing it from sliding down the patient's skin and dripping everywhere, causing dirt and mess to the patient's skin and the surrounding environment. A fixed vertical rod 419 is installed at one end of the top of the mobile base 1. A positioning cylinder 420 is installed at the top of the fixed vertical rod 419. A deflecting long rod 421 is rotatably installed on the middle surface of the positioning cylinder 420. A connecting frame 422 is connected to the bottom of one end of the deflecting long rod 421. Positioning plates 423 are installed at both ends of the bottom of the connecting frame 422. An atomizing cleaning nozzle 424 is installed at one end of the bottom of the positioning plate 423. A gas distribution box 425 is embedded at one end of the positioning plate 423. There is a height difference between the two positioning plates 423. The horizontal plane of one positioning plate 423 is higher than the horizontal plane of the top of the silicone soft block 418, and the horizontal plane of the other positioning plate 423 is higher than the horizontal plane of the top of the inclined support frame 318. A disinfectant storage tank 426 is installed at the top of the mobile base 1, located on one side of the fixed vertical rod 419. A water pump 427 is installed inside the disinfectant storage tank 426. The outlet of the water pump 427 is connected to an infusion pipe 428. A liquid three-way valve 429 is installed at the top of the infusion pipe 428. Both ends of the liquid three-way valve 429 are connected to drain pipes 430. An axial flow fan 431 is installed at the top of the disinfectant storage tank 426. A gas three-way valve 432 is installed at the outlet of the axial flow fan 431. Both ends of the gas three-way valve 432 are connected to exhaust pipes 433. The two drain pipes 430 are connected to two atomizing cleaning nozzles 424, respectively. The two exhaust pipes 430 are connected to the two atomizing cleaning nozzles 424. 3 is connected to the top of the two gas distribution boxes 425 respectively. The bottom of the gas distribution box 425 is provided with an air blowing hole. The water pump 427 and the axial flow fan 431 work together to deliver the disinfectant liquid and gas to the atomizing cleaning nozzle 424 and the gas distribution box 425 through the drain pipe 430 and the exhaust pipe 433 respectively. This sterilizes and cleans the silicone soft block 418 and the inclined receiving frame 318 and dries them with air. No manual disinfection and cleaning is required, which improves work efficiency. Moreover, the cleaning operation can be carried out directly after the nursing is completed, which is convenient for the subsequent nursing of the next patient and reduces the chance of cross-infection between items used by patients. Meanwhile, the connecting frame 422 and the positioning plate 423 can rotate around the positioning cylinder 420 to adjust the position of the positioning plate 423, preventing the positioning plate 423 and the connecting frame 422 from obstructing the nursing operations of medical staff during the nursing process. The heights of the two positioning plates 423 are matched with the heights of the inclined receiving frame 318 and the adhesive silicone soft block 418, respectively, so that the connecting frame 422 can smoothly reach the corresponding cleaning position after rotation, making the operation and use simple.

[0020] The working principle and usage process of this invention are as follows: First, medical staff need to prepare before nursing care by preparing the necessary tools, medicines and other items. The medical staff step on the inclined foot pedal 329, which compresses the return spring 328. The traction rope 330 is pulled and, after being guided and limited by the two guide frames 326 and the guide post 325, the traction rope 330 will pull the movable round rod 322 and the L-shaped moving seat 312 to slide along the guide plate 311. The compression spring 323 is compressed, which increases the distance between the electric push rod 313 and the delivery push block 314 and the circular hollow storage frame 302, thereby making the starting position of the extension of the electric push rod 313 farther away. Then, the electric push rod 313 is activated, extending it forward to push the delivery push block 314 forward and insert it into the operation notch 317. The splicing adsorption block 306 and the item storage frame 308 at the corresponding positions of the operation notch 317 are also pushed forward. The item storage frame 308 extends out of the operation notch 317. Because the electric push rod 313 is pulled backward in advance, the item storage frame 308 is not completely pushed out, and part of it remains inside the operation notch 317. This limits the item storage frame 308 and prevents it from automatically flipping downward. The staff can then place the nursing items inside the item storage frame 308. After the electromagnet 315 is energized, it magnetically fixes and adsorbs the adsorption metal block 316. Then, after the item storage is completed, the electric push rod 313 retracts backward, which can pull the item storage frame 308 back into the storage cavity 305 from the operation notch 317. Next, the rotary motor 310 drives the rotating rod 304 and the rotating transposition frame 303 to rotate, causing the position of the item storage box 308 to change. Under the control of the rotary motor 310, the new item storage box 308 moves sequentially to the operation notch 317. The electric push rod 313 pushes out multiple item storage boxes 308 in sequence for item storage. When storing items, medical staff need to arrange them in the order of use according to the nursing process so that they can be delivered in the order of use when retrieving items later. After the items are stored, the medical staff removes their feet from the inclined foot pedal 329. Under the reset action of the return spring 328 and the compression spring 323, the L-shaped moving seat 312 is pushed forward, pushing the electric push rod 313 close to the circular hollow storage box 302, so that the delivery push block 314 is inserted into the operation notch 317. Before the nursing procedure, the device is pushed to one side of the patient's bed using the mobile base 1. Medical staff adjust the patient's posture to a supine position with the lower limbs extending beyond the bed. The two lower limbs are placed inside the two lower limb arc-shaped positioning slots 410, and secured with elastic straps 411. The staff then starts the drive motor 402. Under the transmission of the drive sprocket 405 and transmission chain 406, the two vertical rotating screws 404 rotate synchronously. The lifting guide block 407 moves upward along the guide frame 403, and the lifting frame 408 and support frame 409 rise synchronously, thereby adjusting the height of the patient's lower limbs. By raising the patient's lower limbs, the patient's buttocks are lifted upward, and the anus is better exposed. This creates a gap between the patient's lower back and the bed. The moving plate 413 and the inclined sponge lumbar support pad 414 are pushed forward along the guide strip 412, inserting the inclined sponge lumbar support pad 414 into the gap below the patient's lower back. This provides support and protection, preventing discomfort caused by prolonged suspension of the lower back. The splicing moving frame 415 and the L-shaped positioning block 416 move together with the moving plate 413, positioning the silicone soft block 418 between the lower back and anus. Medical staff can adjust the height of the silicone soft block 418 by rotating the adjusting screw 417, ensuring it adheres firmly to the skin at a certain distance below the patient's anus. Medical staff begin perianal care. Following the above procedures, the rotary motor 310 drives the rotating transposition frame 303 to rotate, causing the item storage frames 308 to move sequentially to the operating notch 317 and be pushed out by the electric push rod 313. The electric push rod 313 is positioned closer to the circular hollow storage frame 302 than when the items were stored. Thus, when the electric push rod 313 is extended, the item storage frames 308 can be completely pushed out of the operating notch 317. The unbalanced counterweight 309 creates an imbalance of gravity at the bottom of the item storage frames 308 and works in conjunction with the positioning shaft 307 to ensure proper storage of items. The frame 308 automatically tilts downwards, emptying the nursing items stored inside into the inclined receiving frame 318. Subsequently, the electric telescopic rod 320 extends, pushing the arc-shaped fitting and resetting block 321 to tilt forward and fit against the bottom of the item storage frame 308, thus pushing it to reset. When the end of the arc-shaped fitting and resetting block 321 is fully fitted against the bottom of the item storage frame 308, the item storage frame 308 is pushed and rotated back to its original position before tilting, corresponding to the operating notch 317. Under the action of the electric push rod 313 and the electromagnet 315, it can return to the interior of the circular hollow storage frame 302. Medical staff can retrieve the necessary nursing items from inside the tilted receiving frame 318 and repeat the above operation. Different item storage frames 308 are pushed out in sequence to deliver the items, so that medical staff can perform nursing operations according to the delivery order. The operation is more convenient and faster, and cross-infection caused by retrieving items is reduced. When medication is needed during nursing, the medication sprayed around the patient's anus can easily slide down the raised buttocks. However, the silicone soft block 418 intercepts the medication below the patient's anus, preventing it from sliding down and dripping and causing contamination. After the nursing care is completed, both the silicone soft block 418 and the inclined support frame 318 are easily contaminated. Pulling the moving plate 413 and the splicing moving frame 415 back to their original positions ensures that the splicing moving frame 415 and the inclined support frame 318 are on the same vertical plane. Medical staff push the deflection rod 421 to rotate around the positioning cylinder 420, causing the connecting frame 422 to swing 90 degrees. The two positioning plates 423 move to above the silicone soft block 418 and the inclined support frame 318, respectively. Using the water pump 427 and the drainage pipe 430, the disinfectant solution inside the disinfectant storage tank 426 is delivered to the atomizing cleaning nozzle 424, and then through the atomizing cleaning nozzle 424... The spraying process disinfects and cleans the silicone soft block 418 and the inclined receiving frame 318. The sprayed solution falls into the interior of the splicing moving frame 415 and the inclined receiving frame 318, and both the splicing moving frame 415 and the inclined receiving frame 318 maintain a certain tilt angle. The cleaning solution can be automatically discharged outwards. Medical staff can place containers to collect wastewater below in advance. Subsequently, the axial flow fan 431 generates airflow, which is transported and discharged through the exhaust pipe 433 and the gas distribution box 425, blowing it into the interior of the splicing moving frame 415 and the inclined receiving frame 318 to dry the residual cleaning solution, keeping the equipment clean for the next nursing operation.
