Description

Technical Field

[0001] This utility model relates to the field of medical assistive device technology, and in particular to an assistive device to prevent paralyzed patients from sliding down when sitting in bed. Background Technology

[0002] Paralysis is a reduction or loss of voluntary motor function. It is a common symptom of the nervous system and is caused by diseases of the nerves, neuromuscular junctions, or muscles. Treatment should target the primary disease causing the voluntary motor dysfunction, while rehabilitation therapy should be provided at the same time.

[0003] In the nursing care of paralyzed patients, it is inevitable that the patients need to maintain a sitting position in order to facilitate nursing work. However, the patients lack the ability to control themselves and cannot lean on their backs to maintain a sitting position, causing them to slide down involuntarily during the nursing process. This is not only detrimental to the nursing work, but may even cause the patients to bump into the bed during the slide. In this regard, this application proposes an assistive device to prevent paralyzed patients from sliding down when sitting in bed, in order to solve the above problems. Utility Model Content

[0004] To address the above situation and overcome the shortcomings of existing technology, this utility model provides an assistive device to prevent paralyzed patients from slipping while sitting in bed. The technical solution includes a hospital bed and a bed frame integrated with the bed. The bed has a base plate, a backrest integrally connected to the base plate, a seat cushion mounted on the upper part of the base plate, and a lumbar support mounted on the backrest. The base plate has a through groove running front to back. Two crossbars arranged in a front-to-back configuration are fixedly connected to the inner wall of the through groove. A lead screw, rotatably connected to the through groove, is arranged between the two crossbars. The lead screw is threadedly connected to the middle of a moving rod. The moving rod has two sliding sleeves integrally arranged, each corresponding to and slidably connected to one of the crossbars. Mounting rods are fixedly connected to the front and rear ends of the moving rod, and mounting shafts are fixedly connected to the mounting rods. Hip supports located above the seat cushion are fixedly connected to the mounting shafts. A locking plate that engages with the bed frame is integrally arranged on the backrest, and a top screw that abuts against the bed frame is threadedly connected to the locking plate.

[0005] Preferably, the movable rod is integrally provided with a threaded sleeve that is threadedly connected to the lead screw in the middle, and the left end of the lead screw passes through the base plate and is coaxially fixedly connected to a handwheel.

[0006] Preferably, the outer surface of the buttocks support is covered with a sponge pad.

[0007] The beneficial effects of this utility model are:

[0008] In use, the seat cushion, combined with the lumbar support, ensures the comfort of paralyzed patients. After the patient sits on the seat cushion with the assistance of medical staff, a lead screw drives a moving rod to move laterally along the crossbar, allowing the buttock support to move laterally simultaneously. This adjustment of the buttock support provides support against the front of the patient's buttocks, preventing the paralyzed patient from sliding down the seat cushion and ensuring the patient can maintain a sitting posture. Furthermore, the backrest is equipped with a locking plate that engages with the bed frame. Combined with a top screw, this restricts the application from sliding relative to the bed, preventing the paralyzed patient and other components of the application from sliding together relative to the bed, ensuring the stability of the patient while sitting. This application has a simple structure, is easy to use, and is highly practical. Attached Figure Description

[0015] The following is in conjunction with the appendix Figure 1-4 The specific embodiments of this utility model will be described in further detail.

[0016] In the first embodiment, the technical solution is as follows: When in use, the seat cushion 5, in conjunction with the lumbar support 6, ensures the comfort of the paralyzed patient. After the paralyzed patient sits on the seat cushion 5 with the assistance of medical personnel, the moving rod 10 is driven by the lead screw 9 to move laterally along the crossbar 8, thereby allowing the buttock block 14 to move laterally simultaneously. This adjustment of the buttock block 14 provides support against the front of the patient's buttocks, preventing the paralyzed patient from sliding down the seat cushion 5 and ensuring the patient can maintain a sitting posture. Furthermore, the backrest 4 is equipped with a locking plate 15 that can engage with the bed frame 2. Together with the top screw 16, this restricts the sliding of the device relative to the bed 1, preventing the paralyzed patient and other components of the device from sliding together relative to the bed 1, ensuring the stability of the paralyzed patient while sitting. This application has a simple structure, is easy to use, and is highly practical. The base plate 3 has a through groove 7, which conceals the power components such as the crossbar 8 and the lead screw 9.

[0017] In Example 2, based on Example 1, when using this application, the locking plate 15 on the backrest 4 is first fastened to the bed frame 2 of the hospital bed 1, and then the locking screw 16 is tightened. This restricts the application to the hospital bed 1, preventing relative sliding between the application and the hospital bed 1 when the paralyzed patient is sitting, thus ensuring the safety of the paralyzed patient when using the application. Next, the position of the buttock block 14 is adjusted appropriately to facilitate the paralyzed patient's seating. Specifically, the screw 9 is rotated clockwise. A handwheel 18 is provided to facilitate the rotation of the screw 9. The screw 9 can be rotated via the handwheel 18. Clockwise rotation of the screw will act on the moving rod 10 through the screw sleeve 17. The moving rod 10 is slidably mounted on the crossbar 8 through the sliding sleeve 11. Therefore, clockwise rotation of the screw 9 will drive the moving rod 10 to move to the right along the crossbar 8. As the moving rod 10 moves to the right, the mounting rod 12 and mounting shaft 13 will also move to the right simultaneously, and consequently, the buttock block 14 will also move to the right. Correspondingly, turning the lead screw 9 counterclockwise will drive the hip block 14 to move to the left, thereby adjusting the hip block 14 to a position that is roughly suitable for the patient to sit in. Then, the medical staff can further adjust the hip block 14 according to the patient's sitting position using the lead screw 9, so that the hip block 14 fits the patient's hips, thereby improving comfort. The hip block 14 is covered with a sponge pad 19 to ensure the patient's comfort.
