Description

Technical Field

[0001] This utility model relates to the field of fall prevention bed devices, and in particular to a fall prevention guardrail for hospital beds. Background Technology

[0002] Standard hospital beds typically have relatively large gaps between the bed rails, generally designed to prevent adult patients from falling out of bed. However, these beds can be problematic for special patients, such as children, hemiplegic patients, or patients with impaired consciousness. Children are smaller and more active, and their safety awareness is often lower. Some hemiplegic patients are also hyperactive, easily agitated, and prone to impulsive and reckless actions with a strong desire to get out of bed. Therefore, these special patients are highly susceptible to slipping or climbing over the gaps in the bed rails, posing a significant risk of falling out of bed.

[0003] In response, existing technologies have been improved. For example, patent document CN 222942568 U discloses an adjustable fall protection rail for a hospital bed, which includes a hospital bed body, with supporting crossbeams fixed at the front and rear edges of the bed body, and an adjustable guardrail mechanism at the top of each set of supporting crossbeams; the guardrail mechanism prevents patients from falling from the sides of the hospital bed, and the height of the protective net can be adjusted as needed.

[0004] However, when patients need to get out of bed or medical staff need to receive treatment, the barrier mechanism needs to be disassembled to avoid obstruction. It needs to be reinstalled after the procedure, which is cumbersome and redundant. This greatly increases the workload of medical staff and can delay time in emergency situations, making it impractical. Summary of the Invention

[0005] This utility model provides a fall-prevention guardrail for hospital beds. The technical problem to be solved is that the guardrail frame can be folded without disassembling it, thus avoiding obstruction when patients need to get out of bed or when medical staff are performing treatment.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A fall arrestor for a hospital bed includes a fixing component, a railing frame, and a protective component. The protective component is mounted on the railing frame, and the railing frame is fixed to the bed edges on both sides by the fixing component. The railing frame also includes a fixing element. A rectangular block is provided at the lower end of the railing frame. The fixing component has a movable groove, which includes a rectangular limiting groove that matches the rectangular block and a rotating groove communicating with the rectangular limiting groove. The rectangular block is disposed within the movable groove and can rotate within the rotating groove, thereby allowing the railing frame to be folded downwards or slid into the rectangular limiting groove to restrict the rotation of the rectangular block. The fixing element then abuts against the rectangular block to restrict its sliding.

[0007] As a further improvement to the above technical solution: Compared with the prior art, the present invention achieves at least the following beneficial effects: The fall protection rail for hospital beds in the present invention, through the connection and cooperation between the rectangular block and the connected rectangular limiting groove and rotating groove, can realize the flipping, folding or fixing of the rail. When the rail needs to be folded up, it is only necessary to pull out the fixing piece and slide the rail to the rotating groove to flip it down. When the rail needs to be erected, the rail is flipped up and pushed into the rectangular limiting groove, and the fixing piece is inserted to complete the fixing. There is no need to disassemble the rail, and the operation is relatively simple and quick, thereby reducing the workload of medical staff. Attached Figure Description

Therefore, they should not be construed as limiting the scope of protection of this application.

[0013] To address the shortcomings of existing technologies, such as cumbersome operation and poor practicality, the inventors, after careful analysis, discovered that the main reason for these problems with existing fall arrest railings is that the railings need to be disassembled when patients need to get out of bed or when medical staff need to perform treatment. Based on this analysis, the inventors made structural improvements to the fall arrest railing.

[0014] As shown in the figure, a fall-prevention guardrail for a hospital bed according to this utility model includes a fixing component 1, a guardrail 2, a protective component 3, and a fixing element 4. Example

[0015] The fixing component 1 is used to secure the entire guardrail to the edge of the hospital bed and includes a U-shaped fastener 12, a screw 13, and a pressure block 14. The U-shaped fastener 12 can be snapped onto the bed edge, and a threaded hole is provided on one side wall. The screw 13 is inserted into the threaded hole and threadedly engages with the U-shaped fastener 12. The pressure block 14 is located at one end of the screw 13 that extends into the inside of the U-shaped fastener 12, and a handle 131 for easy rotation by hand is fixedly welded to the other end. Optionally, the pressure block 14 is provided with anti-slip texture.

[0016] Rotating the handle 131 can move the pressure block 14, thereby clamping the bed edge together with the other side wall of the U-shaped fastener 12. At the end of the U-shaped fastener 12 away from the opening, there is a movable groove 11. The movable groove 11 is composed of a rectangular limiting groove 111 with a rectangular cross section and a circular rotating groove 112 with a wider section.

[0017] The railing 2 is installed in the movable groove 11, which is composed of a rectangular limiting groove 111 and a rotating groove 112, by a rectangular block 21 at the lower end. When the rectangular block 21 slides into the rectangular limiting groove 111, it cannot rotate under the restriction of the rectangular limiting groove 111. At the same time, the fixing member 4 abuts against the rectangular limiting groove 111, thereby restricting the sliding of the rectangular block 21, so that the railing 2 and the connecting component are relatively fixed. Alternatively, when the rectangular block 21 slides into the rotating groove 112, the rectangular block 21 can rotate in the rotating groove 112, thereby allowing the railing 2 to be flipped down and folded under the sides of the bed. In this case, the railing 2 will not obstruct the patient from getting out of bed or the treatment operation of medical staff.

[0018] The rectangular block 21, connected to the rectangular limiting groove 111 and the rotating groove 112, allows the railing 2 to be flipped, folded, or fixed. To fold the railing 2, simply pull out the fixing piece 4 and slide the railing 2 to the rotating groove 112. To stand the railing 2 upright, flip it up, push it into the rectangular limiting groove 111, and insert the fixing piece 4. No disassembly of the railing 2 is required, making the operation simple and quick, thus reducing the workload of medical staff. Optionally, to prevent the fixing piece 4 from being lost, it can be connected to the U-shaped fastener 12 via a thin rope.

[0019] In this first embodiment, the fixing member 4 is the insert block 41, and the shape formed by the insert block 41 and the rectangular block 21 is exactly matched with the movable groove 11. Therefore, after the rectangular block 21 slides to the end of the rectangular limiting groove 111, the insert block 41 can be inserted into both the rectangular limiting groove 111 and the rotating groove 112, thereby allowing the rectangular block 21 to move.

[0020] The railing 2 includes a fixed frame 22 and a movable frame 23. One end of the movable frame 23 can be retractably inserted into the fixed frame 22, and the movable frame 23 has multiple fixing holes 231 spaced apart along its height. The upper end of the fixed frame 22 is threaded with a fastening bolt 24, which can be inserted into any of the fixing holes 231 to relatively fix the fixed frame 22 and the movable frame 23, so as to adjust the overall height of the railing 2. For ease of manual operation, the fastening bolt 24 can be a wing bolt. Furthermore, to make the railing 2 more comfortable for the patient, it is made of plastic and covered with a flexible material.

[0021] The protective assembly 3 includes a housing 31, a protective net 32, a spring 33, a sleeve 34, and a rotating shaft 35. The housing 31 is fixedly mounted on the upper end of the movable frame 23. The rotating shaft 35 is fixedly mounted inside the housing 31. The sleeve 34 is rotatably fitted onto the rotating shaft 35. The spring 33 is positioned between the rotating shaft 35 and the sleeve 34, with both ends fixedly connected to the rotating shaft 35 and the sleeve 34 respectively. The rotating shaft 35 has a keyway into which the inner end of the spring 33 is inserted. The inner wall of the sleeve 34 has a retaining groove into which the outer end of the spring 33 is engaged. One end of the protective net 32 ​​is wound around the sleeve 34, and this end has a metal clamping strip, which is fastened to the threaded hole of the sleeve 34 with screws. The other end of the protective net 32 ​​extends out of the housing 31. The protective net 32 ​​is made of woven nylon material, is rollable, and has a certain degree of elasticity.

[0022] A pull rod 321 is provided at one end of the protective net 32 ​​extending outside the housing 31, and a buckle 221 is provided at the lower end of the fixing bracket 22. The buckle 221 is an elastic retaining ring with an opening, into which the pull rod 321 can be inserted. The pull rod 321 can be blocked outside the housing 31 or pulled and then fastened inside the buckle 221. Optionally, the buckle 221 can also be made tamper-proof to prevent children or patients from disassembling it themselves.

[0023] When in use, to prevent patients from falling out of bed, the U-shaped fasteners 12 are fastened to the bed edges on both sides, and the handles 131 are tightened. The handles 131 and 14 are used to secure the guardrails. Then, the rectangular block 21 at the bottom of the guardrail 2 is slid into the rotating groove 112, and the guardrail 2 is flipped up to make it vertical. The guardrail 2 is then pushed along the rectangular limiting groove 111, so that the rectangular block 21 slides to the end of the rectangular limiting groove 111. At this time, since the rectangular cross section of the rectangular limiting groove 111 matches the rectangular block 21, the guardrail 2 cannot rotate. Finally, the insert block 41 is inserted so that it passes through both the rectangular limiting groove 111 and the rotating groove 112, blocking the path of the rectangular block 21 to slide back, thus completely fixing the guardrail 2. Finally, the pull rod 321 of the protective net 32 ​​is pulled out and fastened to the buckle 221 below, so that the sides of the bed can be folded to reduce the risk of falling out of bed. When the patient needs to get out of bed or when medical staff need to provide treatment, simply remove the insert 41, then pull the railing 2 outward so that the rectangular block 21 slides into the rotating groove 112, and the railing 2 can be flipped down and folded under the bed. Example

[0024] The railing 2 is installed in the movable groove 11, which is composed of a rectangular limiting groove 111 and a rotating groove 112, by a rectangular block 21 at the lower end. When the rectangular block 21 slides into the rectangular limiting groove 111, it cannot rotate under the restriction of the rectangular limiting groove 111. At the same time, the fixing member 4 abuts against the rectangular limiting groove 111, thereby restricting the sliding of the rectangular block 21, so that the railing 2 and the connecting component are relatively fixed. Alternatively, when the rectangular block 21 slides into the rotating groove 112, the rectangular block 21 can rotate in the rotating groove 112, thereby allowing the railing 2 to be flipped down and folded under the sides of the bed. In this case, the railing 2 will not obstruct the patient from getting out of bed or the treatment operation of medical staff.

[0025] In this second embodiment, the fixing component 4 is a limiting bolt 42, which is threaded onto the U-shaped fastener 12, and one end can be screwed into the rotating groove 112. When it is necessary to fix the railing 2, after pushing the rectangular block 21 to the end of the rectangular limiting groove 111, tighten the limiting bolt 42 so that its end abuts against the side of the rectangular block 21, and fix it by friction. Conversely, loosening the limiting bolt 42 will release the fixation. For ease of manual operation, the limiting bolt 42 can be a wing bolt.

[0026] It should be understood that all the above embodiments are exemplary and not restrictive. Various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of this utility model should be within the protection scope of this utility model.
