Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an improved bed rail. Background Art

[0002] 14.0% to 64.5% of stroke patients experience a history of falls during the acute phase, and 10.5% to 47.0% also experience falls during rehabilitation treatment. Falls can not only cause physical damage to stroke patients but also create psychological fear. Some patients may even suffer fractures as a result of falls, increasing treatment costs and hindering recovery. Currently, rehabilitation treatment for such patients is performed on rehabilitation beds, which lack bedrails. Consequently, clinical rehabilitation treatment presents the following challenges: ① Many treatment sessions typically last over 20 minutes. In actual clinical practice, it is not feasible for medical staff to provide one-on-one bedside support from start to finish. Furthermore, the lack of bedrails on rehabilitation beds makes patients prone to falls. ② During treatment, some family members may not be able to accompany the patient throughout the entire process, making falls more likely during the moment they leave. ③ For patients who are agitated, confused, or restless, the lack of bedrails makes falls more likely.

[0003] Therefore, rehabilitation beds without rails are unsafe to use during treatment and pose a high risk of falls. Although many rehabilitation beds with rails are available on the market, replacing all existing beds would waste resources and be costly. This is especially true for functional lift-type rehabilitation beds, which significantly increase the purchase price. Therefore, to avoid excessive resource waste and reduce costs, the problem of rehabilitation beds without rails can be solved by adding additional rails to existing beds.

[0004] To this end, the Chinese utility model patent application number CN202120271910.9 provides an adjustable bed rail for nursing psychiatric patients, which can be installed on existing beds. However, it is not convenient to lower it, which affects patients getting in and out of bed. The second Chinese utility model patent application number CN201921122316.2 provides a bed rail that prevents patients from falling. After installation, the bed rail can be raised and lowered by pressing the handle, making it easier for patients to get in and out of bed. However, in reality, since the bed rail needs to be raised and lowered from the side of the bed, it will be set on the outside of the bed. Even after it is lowered, the bed rail is located on the outside of the bed, not directly under the bed. This affects the patient's ability to get out of bed and put on shoes to a certain extent, that is, there is a certain inconvenience in use. Utility Model Content

[0028] The bed rails designed in the present invention can be retrofitted onto existing rehabilitation treatment beds without replacing the treatment bed, thus saving costs and resources. Moreover, the bed rails of the present invention are height-adjustable and suitable for use with beds 12 having different requirements.

[0029] Specifically, the bed rail designed in this utility model is installed on the bottom of the treatment bed through the base frame 1, and the fixed part 3 on the base frame 1 is used to achieve stable installation with the bed 12. The support legs 2 support the base frame 1 and the sliding frame 4 and movable rail 5 thereon, thereby achieving stable use of the bed rail. Preferably, the fixed part 3 of this embodiment adopts a hoop-like structure, which is connected to the bed 12 by encircling the foot of the bed 12. The specific structure is as follows: Figure 1 As shown, other clamp structures are also possible. The sliding frame 4 is preferably arranged on top of the base frame 1 to provide better support for the sliding frame 4 and the movable fence 5. Furthermore, a pull ring is provided at one end of the sliding frame 4 extending outside the base frame 1 to facilitate pulling out the sliding frame 4.

[0030] The bedrail of the present invention forms a frame structure with a movable rail 5 and a sliding frame 4. The movable rail 5 can be folded onto the sliding frame 4, which can then slide relative to the base frame 1, allowing the folded movable rail 5 to be stored under the bed 12, preventing the peripheral device from interfering with the patient's normal ingress and egress. Furthermore, the movable rail 5 of the present invention slides relative to the sliding frame 4, allowing the height position of the crossbar 6 to be adjusted, thereby making the bedrail height adjustable. In the present invention, after the vertical bar 7 slides, it can be fixed by a locking member 9, ensuring that the bedrail maintains the desired height.
