Abstract
Description
Technical Field
[0001] This application relates to the field of medical bed technology, and more particularly to a device for assisting patients to turn over in bed. Background Technology
[0002] In the field of medical care, regular turning and transferring patients from bed to bed are crucial aspects of care for those who are bedridden, comatose, or too weak to move independently. However, traditional care methods have many drawbacks.
[0003] In terms of patient turning, in the past, it mainly relied on manual assistance from medical staff or family members. This is not only labor-intensive, usually requiring at least two caregivers to operate together, but also requires a high level of physical strength from the caregivers. At the same time, during manual turning, due to the lack of precise assistive tools, it is difficult to ensure the correct body posture of the patient, which can easily lead to uneven pressure on the patient's body and increase the risk of complications such as pressure sores. Therefore, this patent needs to upgrade and modify the existing technology. Utility Model Content
[0004] In view of the shortcomings of the prior art, this application provides a device for assisting patients to turn over in bed, which overcomes the shortcomings of the prior art and aims to solve the problem that in the past, patients mainly relied on manual assistance from medical staff or family members for turning over. This is not only labor-intensive, but also usually requires at least two nurses to operate together and has high physical requirements for nurses.
[0005] To achieve the above objectives, this application provides the following technical solution: a device for assisting a patient to turn over in bed, comprising a bed body, a connecting layer fixedly connected to the outer side of the bed body, a connecting groove provided inside the connecting layer, a sliding block slidably connected inside the connecting groove, a top fixing layer fixedly connected to the top of the sliding block, connecting blocks fixedly connected to both ends of the outer side of the top fixing layer, a rotating rod rotatably connected inside the connecting block, a fixing groove provided at one end of the top of the bed body near the connecting layer, a fixing rod fixedly connected inside the fixing groove, an auxiliary strap sleeved on the outside of the fixing rod, the auxiliary strap extending outward from one end of the top until it reaches the other end of the bed body.
[0006] By adopting the above technical solution, when in use, the patient only needs to lie flat on the top of the bed. At this time, medical staff can perform basic examinations and treatments on the patient. When the patient becomes unconscious or is unable to turn to the side on their own, but needs to be examined or treated in a lateral position, the sliding block is slid upward along the connecting groove, thereby causing the top fixing layer to rise a certain distance. At this time, the end of the auxiliary belt is grasped and fixed to the outside of the rotating rod. The auxiliary belt then wraps around the patient. Then, the rotating rod is rotated so that the auxiliary belt rotates around the rotating rod and rolls up on the outside of the rotating rod. As the auxiliary belt rolls up on the outside of the rotating rod, it will cause the patient to turn to the side towards the top fixing layer. At this time, the rotation of the rotating rod is stopped, thereby supporting the patient's lateral position. Then, medical staff can perform further examinations and treatments on the patient.
[0007] As a preferred technical solution of this application, a fixing block is fixedly connected to the bottom of the bed body directly below the fixing groove. The sliding block has a sliding groove inside. A fixing screw is fixedly connected to the outside of the fixing block. The fixing screw passes through the sliding groove and is threaded to the outside of the fixing nut. The fixing nut is tightly fitted to the outside of the sliding block.
[0008] By adopting the above technical solution and setting the fixed screw, when the patient needs to turn to the side, the fixed nut can be loosened and the sliding block can be slid upward. Since the sliding block has a sliding groove inside, the sliding groove can limit the sliding block. After the sliding block rises to the limit height, the fixed nut is tightened to fix the position of the sliding block. At the same time, the setting of the sliding block can play a certain protective role for the patient and prevent the patient from falling out of the bed when turning to the side.
[0009] As a preferred technical solution of this application, a hanging rod is fixedly connected to the outer side of the rotating rod, and a hook is fixedly connected to the end of the auxiliary belt.
[0010] By adopting the above technical solution, the hook can be locked inside the hanging rod during use, thereby fixing the auxiliary belt to the outside of the rotating rod.
[0011] As a preferred technical solution of this application, a rocker arm is rotatably connected to one end of the outer side of the connecting block, and the rotating end of the rocker arm passes through the connecting block and is fixedly connected to the rotating rod.
[0012] By adopting the above technical solution, after the auxiliary belt is fixed on the outside of the rotating rod, the operator can manually rotate the rocker to drive the rotating rod to rotate, and then the rotation of the rotating rod will cause the outer auxiliary belt to be rolled up to the outside of the rotating rod.
[0013] As a preferred technical solution of this application, the top of the bed is provided with a flip-up layer, one end of which is fixedly connected to a hinge, and a flip plate is rotatably connected to the outside of the hinge.
[0014] By adopting the above technical solution, the flip panel can rotate around the hinge, thereby tilting one end of the bed upwards and helping the patient to sit up.
[0015] As a preferred technical solution of this application, the bottom of the bed body is provided with a rack groove directly below the flipping layer, the bottom of the flipping plate is fixedly connected with a rack, the bottom of the bed body is fixedly connected with a motor at the position outside the rack groove, the drive end of the motor is fixedly connected with a gear, the gear and the rack are meshed with each other, and the rack has a semi-circular arc structure.
[0016] By adopting the above technical solution, the motor is started, which drives the gear to rotate. During the rotation of the gear, the outer meshing rack moves. The movement of the rack drives the top flap to rotate around the hinge, thereby enabling the patient to get up.
[0017] As a preferred technical solution of this application, bed legs are fixedly connected to both ends of the bed body.
[0018] By adopting the above technical solution, the bed legs can provide overall support for the bed frame.
[0019] The beneficial effects of this application are:
[0020] In this invention, medical staff can achieve the patient's side-turning by simply performing a few steps, such as sliding the sliding block, fixing the auxiliary belt, and turning the rocker arm. This eliminates the need for multiple people to work together or to expend a lot of physical strength, greatly improving nursing efficiency. In particular, it can quickly adjust the patient's position in emergency situations. This device is suitable for patients who are unable to turn over on their own due to coma, physical weakness, or other reasons, providing an effective turning solution for patients with different symptoms and physical conditions.
[0021] 2. In this utility model, the automatic rotation of the flip plate is achieved by the meshing of the gear and rack driven by the motor, thereby helping the patient to stand up. This automated design is more labor-saving and precise than the traditional manual method of raising the bed, and the angle of standing up can be flexibly adjusted according to the patient's needs.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0030] Reference Figure 1-6 A device for assisting a patient to turn over in bed includes a bed body 1. The device is characterized by a connecting layer 2 fixedly connected to the outer side of the bed body 1, a connecting groove 3 inside the connecting layer 2, a sliding block 5 slidably connected inside the connecting groove 3, a top fixing layer 6 fixedly connected to the top of the sliding block 5, connecting blocks 7 fixedly connected to both ends of the outer side of the top fixing layer 6, a rotating rod 8 rotatably connected inside the connecting block 7, a fixing groove 9 located at one end of the top of the bed body 1 near the connecting layer 2, a fixing rod 10 fixedly connected inside the fixing groove 9, and an auxiliary strap 11 sleeved on the outer side of the fixing rod 10, extending outward from one end of the top to the other end of the bed body 1. In use, the patient simply lies flat on top of the bed body 1, at which point medical personnel can assist the patient. For basic examination and treatment, when a patient is unconscious or unable to turn to their side but requires examination and treatment, the sliding block 5 is slid upward along the connecting groove 3, thereby causing the top fixing layer 6 to rise a certain distance. At this time, the end of the auxiliary belt 11 is grasped and fixed to the outside of the rotating rod 8. The auxiliary belt 11 then wraps around the patient. The rotating rod 8 is then rotated, causing the auxiliary belt 11 to rotate around the rotating rod 8 and roll up on the outside of the rotating rod 8. As the auxiliary belt 11 rolls up on the outside of the rotating rod 8, it will cause the patient to turn to their side towards the top fixing layer 6. At this time, the rotation of the rotating rod 8 is stopped, thus supporting the patient's side-lying position. Medical staff can then conduct further examination and treatment on the patient.
[0031] In this embodiment, as Figure 1 - Figure 6 As shown, a fixing block 4 is fixedly connected to the bottom of the bed 1 directly below the fixing groove 9. A sliding block 5 has a sliding groove 16 inside. A fixing screw 17 is fixedly connected to the outside of the fixing block 4. The fixing screw 17 passes through the sliding groove 16 and is threaded to the outside of the fixing nut 18. The fixing nut 18 fits tightly against the outside of the sliding block 5. With the setting of the fixing screw 17, when the patient needs to turn to the side, the fixing nut 18 can be loosened and the sliding block 5 can be slid upward. Since the sliding block 5 has a sliding groove 16 inside, the sliding groove 16 can limit the sliding block 5. After the sliding block 5 rises to the limit height, the fixing nut 18 is tightened to fix the position of the sliding block 5. At the same time, the setting of the sliding block 5 can play a certain protective role for the patient to prevent the patient from falling out of the bed 1 when turning to the side.
[0032] In this embodiment, as Figure 1 - Figure 6 As shown, a hanging rod 24 is fixedly connected to the outer side of the rotating rod 8, and a hook 23 is fixedly connected to the end of the auxiliary belt 11. In use, the hook 23 can be locked inside the hanging rod 24 to fix the auxiliary belt 11 to the outer side of the rotating rod 8.
[0033] In this embodiment, as Figure 1 - Figure 6 As shown, a rocker arm 12 is rotatably connected to one end of the outer side of the connecting block 7. The rotating end of the rocker arm 12 passes through the connecting block 7 and is fixedly connected to the rotating rod 8. When the auxiliary belt 11 is fixed to the outside of the rotating rod 8, the operator can manually rotate the rocker arm 12 to drive the rotating rod 8 to rotate. Then, the rotation of the rotating rod 8 will drive the outer auxiliary belt 11 to be wound to the outside of the rotating rod 8.
[0034] In this embodiment, as Figure 1 - Figure 6 As shown, a flip-up layer 13 is provided at the top of the bed 1. A hinge 14 is fixedly connected to one end of the flip-up layer 13. A flip plate 15 is rotatably connected to the outside of the hinge 14. The flip plate 15 can rotate around the hinge 14, thereby tilting one end of the bed 1 upward, thus helping the patient to sit up.
[0035] In this embodiment, as Figure 1 - Figure 6As shown, the bottom of the bed body 1 is provided with a rack groove 19 directly below the flip layer 13. A rack 20 is fixedly connected to the bottom of the flip plate 15. A motor 22 is fixedly connected to the bottom of the bed body 1 at the position outside the rack groove 19. A gear 21 is fixedly connected to the drive end of the motor 22. The gear 21 and the rack 20 are meshed with each other. The rack 20 has a semi-circular arc structure. By starting the motor 22, the gear 21 is driven to rotate. During the rotation of the gear 21, the outer meshing rack 20 will be moved. The movement of the rack 20 will drive the top flip plate 15 to rotate around the hinge 14, thereby enabling the patient to get up.
[0036] In this embodiment, as Figure 1 - Figure 6 As shown, bed legs 25 are fixedly connected to both ends of the bed frame 1. The bed legs 25 can provide support for the entire bed frame 1.
[0037] Working principle: When a patient needs to turn to the side for examination and treatment but cannot turn to the side independently, first loosen the fixing nut 18 on the outside of the fixing screw 17 on the fixing block 4. Since the sliding block 5 has a sliding groove 16 inside, the sliding groove 16 can limit the sliding block 5. At this time, slide the sliding block 5 upward along the connecting groove 3, driving the top fixing layer 6 to rise to a suitable distance. After rising to the position, tighten the fixing nut 18 to fix the position of the sliding block 5. Grasp the end of the auxiliary belt 11 and lock the hook 23 at the end of the auxiliary belt 11 onto the hanging rod 24 on the outside of the rotating rod 8 to fix the auxiliary belt 11 on the outside of the rotating rod 8. At this time, the auxiliary belt 11 covers the patient. Manually rotate the rocker arm 12 on the outside of the connecting block 7. The rotating end of the rocker arm 12 passes through the connecting block 7 and is fixedly connected to the rotating rod 8. Therefore, the rotation of the rocker arm 12 will drive the rotating rod 8 to rotate, thereby causing the auxiliary belt 11 to rotate around the rotating rod 8 and roll up on its outside. When belt 11 is wound up, the auxiliary belt 11 will cause the patient to turn to the side towards the top fixed layer 6. When the patient turns to the appropriate angle, the rocker arm 12 will stop turning. At this time, the auxiliary belt 11 will support the patient's side position, and medical staff can conduct further examinations and treatments on the patient. If it is necessary to assist the patient to get up, the motor 22 located outside the rack groove 19 at the bottom of the bed 1 will be started. The gear 21 at the drive end of the motor 22 will start to rotate. Since the gear 21 and the semi-circular rack 20 fixedly connected to the bottom of the flip plate 15 are meshed, the rotation of the gear 21 will drive the rack 20 to move. The movement of the rack 20 will cause the top flip plate 15 to rotate around the hinge 14, thereby tilting the flip layer 13 at one end of the bed 1 upward, causing the patient to get up. When the patient gets up to the appropriate angle, the motor 22 will stop working. When the patient needs to lie down again, the motor 22 only needs to be controlled to rotate in the opposite direction to drive the flip layer 13 back to its original position.
[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
