Abstract
Description
Technical Field
[0001] This utility model relates to the field of anti-fall devices, and in particular to an anti-fall device for elderly patients in hospitals. Background Technology
[0002] In hospital settings, elderly patients, due to declining physical function and reduced mobility and balance, are particularly vulnerable to falls, which pose a serious threat to their health and safety. Statistics show a persistently high incidence of falls among elderly patients in hospitals. The resulting fractures, traumatic brain injuries, and other serious consequences not only prolong hospital stays and increase medical costs but can also cause significant harm to patients' lives and health. The risk of falls is particularly high in specific environments such as restrooms, making the development of an effective fall prevention device for elderly patients in hospitals an urgent priority.
[0003] Currently, common fall prevention equipment in hospitals mainly includes anti-slip flooring, such as anti-slip tiles and mats, as well as walking aids such as canes and walking aids. Anti-slip flooring primarily reduces the likelihood of patients slipping by increasing the friction between the floor and the soles of their shoes; canes and walking aids help patients maintain their balance while walking, providing additional support. These devices offer some degree of protection for elderly patients.
[0004] However, existing devices have a significant problem: when elderly patients stand up, their body posture changes rapidly, which can easily lead to insufficient blood supply to the brain, causing symptoms such as dizziness and vertigo. This makes it difficult for them to maintain their balance and increases the risk of falls. Existing fall prevention devices cannot intervene in this sudden situation in time and cannot provide effective support and protection for elderly patients at the critical moment of standing up, leaving them still at a high risk of falling during this process. Therefore, a fall prevention device for elderly patients in hospitals is proposed to solve the above problems. Utility Model Content
[0005] To address the above shortcomings, this utility model provides a fall prevention device for elderly patients in hospitals, aiming to improve the problem that elderly patients are prone to falling due to insufficient blood supply to the brain when they suddenly stand up after using the toilet.

[0013] The locking assembly includes a gear and a locking block. The inner wall of the gear is fixedly connected to the other end of the rotating shaft. The inner wall of the gear engages with the locking block. The gear is located on the inner wall of the protective cover on one side.
[0014] As a further description of the above technical solution:
[0015] A fixing frame is fixedly connected to the outer wall of the limiting plate on the other side, and a rotating bar is rotatably connected inside the fixing frame.
[0016] As a further description of the above technical solution:
[0017] A connecting plate is fixedly connected to the outer wall of the rotating bar. One side of the connecting plate is fixedly connected to the outer wall of the card block. A limiting block is fixedly connected to the outer wall of the connecting plate. The limiting block is in contact with the inner wall of the fixing frame.
[0018] As a further description of the above technical solution:

[0020] As a further description of the above technical solution:
[0021] A fixing block is fixedly connected to the outer wall of the limiting plate on the other side, and an electric telescopic rod is fixedly connected inside the fixing block. The output end of the electric telescopic rod is in contact with the connecting plate.
[0022] This utility model has the following beneficial effects:
[0023] In this invention, a fixed belt connects the device to the elderly patient, and a spiral spring pushes the connecting belt outward. Finally, the engagement between the gear and the locking block prevents the connecting belt from accidentally stretching outward on one side, thus achieving a protective effect for the elderly patient.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1-5This utility model provides an embodiment of a fall prevention device for elderly patients in hospitals, comprising an L-shaped support frame 1. The L-shaped support frame 1 is internally threaded with expansion bolts 2, which are used to firmly fix the L-shaped support frame 1 to a wall or supporting structure to ensure the stability of the entire device. A fixing hook 3 is provided on the outer wall of the L-shaped support frame 1, serving as a connection point for suspending subsequent components. A pull ring 4 is provided on the outer wall of the fixing hook 3, acting as a transition connection to make the force more even. A connecting plate 9 is fixedly connected to one end of the pull ring 4, which serves as a core connecting component integrating multiple functional components. Limiting plates 5 are fixedly connected to both sides of the connecting plate 9, limiting the axial movement range of the rotating shaft 10. The two limiting plates 5 are connected in rotation. A rotating shaft 10 is connected, serving as a central pivot for extending and retracting the connecting belt 6. The connecting belt 6 is fixedly connected to the outer wall of the rotating shaft 10, directly connecting to the user and transmitting tension. A reset component is provided at one end of the rotating shaft 10, providing force for automatically retracting the connecting belt 6. A locking component is provided at the other end of the rotating shaft 10, locking the rotating shaft 10 in an emergency to prevent the connecting belt 6 from extending further. A fixing strap 7 is provided on one side of the connecting belt 6, used to comfortably secure it to the user. Buckles 8 are fixedly connected between the two sides of the fixing strap 7, allowing for quick adjustment of the tightness of the fixing strap 7. The reset component includes a spiral spring 11, which stores elastic potential energy for automatically retracting the connecting belt 6. One side of the spiral spring 11 is fixedly connected to... Inside one end of the rotating shaft 10, a fixed plate 12 is fixedly connected to the other side of the spiral spring 11. The fixed plate 12 fixes the spiral spring 11 to the limiting plate 5. One side of the fixed plate 12 is fixedly connected to the outer wall of one limiting plate 5. Protective covers 13 are fixedly connected to the outer walls of both limiting plates 5. The protective covers 13 protect the internal mechanism from dust and damage. The locking assembly includes a gear 14 and a locking block 15. The gear 14 converts the rotational motion of the rotating shaft 10 into a locking action. The inner wall of the gear 14 is fixedly connected to the other end of the rotating shaft 10. The inner wall of the gear 14 engages with the locking block 15. The locking block 15 prevents the gear 14 from rotating in an emergency. The gear 14 is located on the inner wall of one protective cover 13. A fixed frame 17 is fixedly connected to the outer wall of the other limiting plate 5. The fixed frame 17 is a locking mechanism. The positioning mechanism provides the installation base. A rotating bar 16 is rotatably connected inside the fixed frame 17, acting as a lever fulcrum to allow the locking block 15 to swing. A connecting plate 22 is fixedly connected to the outer wall of the rotating bar 16, linking multiple locking components together. One side of the connecting plate 22 is fixedly connected to the outer wall of the locking block 15, and a limiting block 18 is fixedly connected to the outer wall of the connecting plate 22, restricting the swing range of the connecting plate 22. The limiting block 18 fits against the inner wall of the fixed frame 17. A spring strip 19 is provided on one side of the connecting plate 22, providing the elastic force for the locking block 15 to reset. One end of the spring strip 19 is fixedly connected to the inner wall of the fixed frame 17, and the other end is fixedly connected to the outer wall of the connecting plate 22. A fixing block 20 is fixedly connected to the outer wall of the limiting plate 5 on the other side.The fixing block 20 provides a stable mounting point for the electric telescopic rod 21. The electric telescopic rod 21 is fixedly connected inside the fixing block 20. The electric telescopic rod 21 acts as a power source to control the movement of the locking mechanism. The output end of the electric telescopic rod 21 is in contact with the connecting plate 22.
[0033] Working principle: During equipment use, the fixing strap 7 is first fixedly connected to the user's armpit by the buckle 8. Then, the controller drives the output end of the electric telescopic rod 21 to move. Since the output end of the electric telescopic rod 21 is in contact with one side of the connecting plate 22, the movement of the output end of the electric telescopic rod 21 will drive the connecting plate 22 to rotate around the rotating bar 16, and push the spring bar 19 to compress and the locking block 15 to move out of the inner wall of the gear 14. Next, the connecting strap 6 is pulled outward. During this process, the connecting strap 6 will drive the rotating shaft 10 to rotate clockwise and cause the spiral spring 11 to expand outward. When the connecting strap 6 is stretched outward to a suitable length, the controller drives the output end of the electric telescopic rod 21 to retract. The rebound force of the spring bar 19 pushes the locking block 15 on one side of the connecting plate 22 to move back to the inner wall of the gear 14. At this time, the limiting block 18 on one side of the connecting plate 22 will be in contact with the inner wall of the fixing frame 17. When an elderly patient suddenly stands up after using the toilet, the rebound characteristic of the spiral spring 11 will push the connecting belt 6 to contract. At this time, the gear 14 will also rotate counterclockwise. While rotating, the gear 14 will push the locking block 15 to rotate around the rotating bar 16. The elasticity of the spring bar 19 provides room for the locking block 15 to rotate and move. When the elderly patient suddenly stands up, the blood supply to the brain is insufficient, causing the body to tilt forward during the fall. The gear 14 on the outer wall of the rotating shaft 10 will rotate clockwise through the connecting belt 6, causing the locking block 15 to rotate and move around the rotating bar 16. However, because the limiting block 18 and the fixing frame 17 are in close contact, the locking block 15 is difficult to rotate and moves. It is always locked on the inner wall of the gear 14, fixing the angle of the rotating shaft 10 and preventing the connecting belt 6 from continuing to stretch outward, which would cause the elderly patient to fall. This achieves the protection effect for the elderly patient.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 the present utility model should be included within the protection scope of the present utility model.
