Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical equipment, and in particular to an adjustable protective bed rail. Background Technology
[0002] In the field of medical care, hospital beds, operating beds, and other similar facilities are usually equipped with guardrails to prevent patients (especially those who are post-operative, comatose, or unconscious) from falling out of bed while in bed, thus ensuring their safety.
[0003] However, most existing bed rails are of fixed height or offer only a limited number of fixed positions, failing to flexibly adapt to the specific needs of patients of different heights and body types, nor can they be quickly adjusted according to the needs of clinical procedures (such as surgery, dressing changes, and vital sign monitoring). Overly high rails may cause inconvenience for medical staff, while overly low rails pose safety hazards.
[0004] Furthermore, traditional safety railings are mostly foldable or detachable as a whole. When folded down, they take up a lot of space, and when disassembled, they are inconvenient to store. They are also not convenient to operate when assisting patients to get in and out of bed, which affects nursing efficiency. Therefore, there is an urgent need for a safety railing structure that can be infinitely adjustable, easy to operate, and can be flexibly opened and closed.
[0005] Therefore, a technical solution to the above problems is needed. Utility Model Content
[0006] In order to solve the technical problems existing in the prior art, the purpose of this utility model is to provide an adjustable protective bed rail to solve the above-mentioned technical problems.
[0007] To achieve its purpose, the present invention adopts the following technical solution: An adjustable safety bed rail includes: Bed frame; A guardrail is installed on the side of the bed. The guardrail includes a fixed block installed on the side of the bed, an adjustment structure set on the fixed block, and a handrail connected to the adjustment structure. The adjustment structure can adjust the distance between the handrail and the fixed block, thereby controlling the height of the handrail. Furthermore, the fixing block is rotatably connected to the bed body, and the bed body is also provided with a fixing component for locking the fixing block in the protective state.
[0008] In some embodiments, the adjustment structure includes a drive device, a lead screw driven to rotate by the drive device, a first slider cooperating with the lead screw, a second slider connected to the handrail, and a scissor arm connected between the first slider and the second slider. When the drive device rotates, it drives the lead screw to rotate, which in turn moves the slider, thereby changing the included angle of the scissor arm and realizing the lifting and lowering of the handrail relative to the fixed block.
[0009] In some embodiments, the fixed block is hollow and has a groove, the lead screw and the slider are housed in the groove, and the scissor arm passes through an opening on the fixed block and is connected to the slider.
[0010] In some embodiments, the scissor arm includes two connecting rods rotatably connected at the middle, one end of each connecting rod being hinged to slider one and the other end being hinged to slider two.
[0011] In some embodiments, the lead screw is provided with multiple sets of adjusting threads, each set of adjusting threads including two threaded segments with opposite directions of rotation, and the two sliders connected to one of the scissor arms respectively engage with the two threaded segments in one set of adjusting threads.
[0012] In some embodiments, the driving device is a drive motor, which is connected to the lead screw drive.
[0013] In some embodiments, the fixing component includes an elastic element and a locking element, the bed body has a mounting cavity, and the elastic element and the locking element are housed in the mounting cavity; the fixing block has a locking hole, the elastic element acts on the locking element, so that the locking element partially extends into the mounting cavity and engages with the locking hole; the locking element is connected to a handle for controlling the locking element to disengage from the locking hole, and the handle at least partially extends out of the bed body.
[0014] In some embodiments, the bottom of the bed is provided with casters equipped with foot brakes.
[0015] In some embodiments, the guardrails are symmetrically arranged on the left and right sides of the bed.
[0016] This invention utilizes an adjustment structure composed of a lead screw and a scissor arm to achieve smooth, stable, and stepless height adjustment of the safety railing. It allows for precise adjustment to the optimal height based on the patient's specific condition and medical procedure requirements, effectively preventing falls from bed while avoiding the limitations of fixed heights, thus offering wider adaptability. Furthermore, the height adjustment process can be easily completed manually or electrically, saving time and effort, and the flexible height adjustment provides patients with a more comfortable protective experience.
[0017] This utility model's protective railing can be flipped open close to the side of the bed without taking up extra space, solving the problem of inconvenient folding of traditional railings. The unique side-flipping design, combined with easy-to-operate locking components, allows medical staff to quickly open or close the railing, greatly facilitating patient entry and exit from bed and daily care, reducing feelings of oppression and constraint, and significantly improving work efficiency.

[0026] See Figure 1 The diagram shown is a structural schematic of an adjustable protective bed rail according to this utility model.
[0027] See Figures 1 to 7 An adjustable protective bed rail includes a bed frame 100 and a protective rail 200 disposed on the side of the bed frame 100. The protective rail 200 is installed on the bed frame 100 and can be adjusted in height and flipped. In use, the protective rail 200 can be easily adjusted to effectively protect patients while stopping at different heights to adapt to the needs of different patients and facilitate use by medical staff, thereby improving work efficiency, increasing the stability of the operating table, ensuring patient safety during use, and guaranteeing comfort. In addition, the protective rail 200 can be flipped and opened on one side of the bed frame 100 to facilitate patients getting in and out of bed.
[0028] The bed 100 mentioned in this utility model can support the patient during surgery and adjust the patient's position according to the needs of the surgical procedure, providing a convenient surgical environment for the doctor. The bed 100 is a basic piece of equipment in the operating room, and generally consists of a support plane 110 and support legs 120. Specifically, in this embodiment, the support plane 110 of the bed 100 is a large cuboid shape, and the support legs 120 are installed at the bottom of the support plane 110. Four support legs 120 are provided to support the four corners of the roughly cuboid support plane 110 respectively, maintaining the stability of the support plane 110.
[0029] Preferably, see Figure 1 The bed 100 is also movable to accommodate adjustments made by medical staff. Specifically, in this embodiment, casters 130 are provided on the bottom surfaces of the support legs 120 at the bottom of the bed 100. In particular, casters 130 are provided on the bottom of all four support legs 120, allowing the bed 100 to be easily adjusted in position. Foot brakes can also be installed on the casters 130 to fix the bed 100 in place, ensuring it remains stationary when not in use, preventing unnecessary displacement, and guaranteeing stable and safe operation.
[0030] See Figure 2 and Figure 3 The guardrails 200 are installed on the left and right sides of the bed 100. Each guardrail 200 on the left and right sides of the bed 100 includes a fixing block 210 installed on the bed 100, an adjustment structure 220 installed on the fixing block 210, and a handrail 230 connected to the adjustment structure 220. By adjusting the adjustment structure 220, the height of the handrail 230 of the guardrail 200 can be adjusted, thus making the height of the guardrail 200 adjustable.
[0031] Specifically, in this embodiment, the fixing block 210 is a long, rod-shaped structure with a length approximately the same as that of the bed 100, and is installed on the side of the bed 100. The fixing block 210 has a hollow interior forming a sliding groove 211. (See reference...) Figure 2 and Figure 4 The adjusting structure 220 includes a lead screw 221 installed in the fixed block 210, a slider 222 installed on the lead screw 221, a slider 223 installed on the handrail 230, and a scissor arm 224 connecting the slider 222 and the slider 223. The slider 222 can move on the lead screw 221, and the slider 223 can move on the handrail 230. The scissor arm 224 includes two connecting rods 2241 rotatably connected in the middle. The two connecting rods 2241 of each scissor arm 224 are respectively connected by two... Slider 1 222 and two sliders 223 are respectively connected to the fixed block 210 and the handrail 230. That is, one end of the connecting rod 2241 is connected to slider 1 222 and the other end is connected to slider 223. When the two sliders 1 222 or the two sliders 223 move relative to each other, the end distance between the two connecting rods 2241 changes, the scissor angle of the scissor arm 224 changes, and the height of the scissor arm 224 changes. In other words, the height of the handrail 230 on the fixed block 210 can be changed, and the height of the guardrail 200 can be changed.
[0032] The fixed block 210 has an opening 212, the slider 222 is mounted on the lead screw 221, and the scissor arm 224 can extend into the slide groove 211 through the opening 212 to connect with the slider 222.
[0033] Preferably, when the connecting rod 2241 is connected to the first slider 222 and the second slider 223, the connecting rod 2241 is hinged to both the first slider 222 and the second slider 223. The connecting rod 2241 can rotate relative to the first slider 222 and the second slider 223, so that the first slider 222 or the second slider 223 can move relative to each other. The scissor arm 224 can change its angle and height.
[0034] Preferably, the lead screw 221 is provided with multiple sets of adjusting threads 2211, each set of adjusting threads 2211 including two opposing threads. Two sliders 222 connected to a scissor arm 224 respectively engage with the two opposing threads. When the lead screw 221 rotates, the two sliders 222 can move relative to each other, changing the height of the scissor arm 224, thereby completing the adjustment of the height of the guardrail 200.
[0035] Alternatively, in some other embodiments, the interior of the handrail 230 can be hollow to form a groove 211, and the lead screw 221 can be set in the groove 211. The slider 223 can be moved by rotating the lead screw 221, so that the two angles of the scissor arm 224 can be changed, thereby raising and lowering the handrail 230 and adjusting its height.
[0036] Preferably, the system further includes a drive device 225 for driving the lead screw 221 to rotate. The drive device 225 is connected to the lead screw 221 in a transmission manner. By setting the drive device 225, the lifting and lowering of the handrail 230 can be automatically controlled, making it convenient for patients to use. Specifically, in this embodiment, the drive device 225 is a drive motor.
[0037] The fixing block 210 is rotatably mounted on the side of the bed frame 100, allowing the armrest 230 to be flipped on the side of the bed frame 100 and opened on one side of the bed frame 100, facilitating the patient's getting in and out of bed. Specifically, in this embodiment, the fixing block 210 has cylindrical protrusions 213 at both ends, and the bed frame 100 has a circular groove. The fixing block 210 is mounted in the circular groove through the cylindrical protrusions 213 at both ends, and can rotate on the bed frame 100.
[0038] See Figure 1 , Figure 5 , Figure 6 and Figure 7 It also includes a fixing component 300 for fixing the fixing block 210. When the handrail 230 is in normal use on the side of the bed 100, the fixing component 300 fixes the fixing block 210 on the bed 100 so that it cannot be flipped over, so that the handrail 230 can be used normally. When the patient needs to get out of bed, the fixing component 300 no longer fixes the fixing block 210, and the handrail 230 can be flipped over and opened on one side of the bed 100 to facilitate the patient getting in and out of bed.
[0039] Specifically, see Figure 5 and Figure 7 In this embodiment, the fixing component 300 includes an elastic element 310 and a locking element 320. The bed body 100 is also provided with an installation cavity. Both the elastic element 310 and the locking element 320 are disposed in the installation cavity. The installation cavity communicates with the circular groove of the cylindrical protrusion of the fixing block 210 on the bed body 100. The cylindrical protrusion 213 on the fixing block 210 is also provided with a locking hole 214. The elastic element 310 acts between the wall of the installation cavity and the locking element 320. Under the elastic action of the elastic element 310, the locking element 320 can partially extend into the circular groove and engage with the locking hole 214 of the cylindrical protrusion 213, thereby fixing the fixing block 210. Furthermore, the locking component 320 is provided with a handle 330, which can extend out of the mounting cavity and the bed 100. When in use, the locking component 320 can be controlled by the handle 330, so that the locking component 320 overcomes the elastic force and is no longer fixed to the fixing component, allowing the fixing component to rotate and the armrest 230 to be opened on the side of the bed 100.
[0040] When using the device of the present invention: First, the bed 100 is moved and fixed by the foot brake moving wheel 130. When it is necessary to adjust the height of the guardrail 200, the lead screw 221 in the fixing block 210 can be electrically driven to unfold or retract the scissor arm 224 structure connected thereto, thereby smoothly raising and lowering the handrail 230 to the required height to meet the needs of different patients or medical operations.
[0041] When a patient needs to get in or out of bed, the handle 330 located on the side of the bed is operated, causing the locking element 320 to overcome the internal spring force. The locking element 320 then disengages from the locking hole 214 of the fixing block 210, allowing the entire guardrail 200 to flip outward and open the safety passage. After assisting the patient in getting in or out of bed, the guardrail 200 is returned to the vertical position. The internal spring will cause the locking element 320 to automatically spring back and lock, ensuring that the guardrail 200 is stable and reliable.
[0042] The entire process achieved flexible and adjustable height of the 200mm guardrail, with convenient flip-opening and closing. While providing effective safety protection, it greatly facilitated medical staff operations and patients' daily lives, improving overall safety and work efficiency.
[0043] The above are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
