Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of in-home bathing assistance industry, and particularly relates to a manually adjustable and folding bathing bed and a bathing assistance method. Background Technology
[0002] With the country's population aging rapidly and the rise of the in-home bathing service industry, the existing equipment in this industry is mainly of two types: inflatable bath tubs and split-type bathtubs. Inflatable bath tubs need to be operated while the elderly are lying in bed, requiring the user to turn over multiple times to get in and out of the tub. Water and drainage are very difficult, and storage is cumbersome, with inflation and deflation taking a long time. Split-type bathtubs are bulky and cannot be transported by car. Moving them on a ladder is very strenuous, requiring two or more people to lift the elderly into and out of the tub. The process is extremely painful and inconvenient, and there is a high risk of injury such as bumps and slips.
[0003] Current market-available structures fail to address the issues of transport volume and operational safety; their lack of convenient water and drainage, lifting functionality, and reliance on caregivers' physical strength for transfer increases the risk of secondary injury to the elderly. Summary of the Invention
[0004] This invention provides a manually adjustable and foldable bath bed and a bathing assistance method, the specific technical solution of which is as follows: A manually adjustable folding bath bed includes a foldable segmented bed frame, guardrails, scissor legs, sliders, lead screws, lead screw bearing seats, stabilizer bars, stabilizer bar seats, lifting cranks, casters, folding hinges, and a matching bath tub. The foldable segmented bed frame consists of three bed boards connected by folding hinges, forming a compact cuboid structure when folded. The guardrails are symmetrically arranged on both sides of the foldable segmented bed frame and are connected to the foldable segmented bed frame by hinges, and can be flipped outward or folded inward. The foldable segmented bed is provided with a lead screw bearing seat and a stabilizer seat underneath, with the stabilizer seat located on both sides of the lead screw bearing seat. The stabilizer bar is installed inside the stabilizer seat to prevent tilting during lifting; The scissor legs are located below the foldable segmented bed, and the scissor legs are connected to the lead screw via a slider; both ends of the lead screw are fixed to the bottom of the foldable segmented bed via lead screw bearing seats. The crank handle is connected to one end of the lead screw, and the lead screw is driven to rotate by the crank handle; The casters are located at the ends of the scissor lift legs for easy movement and fixation; The bath tub can be detached and embedded into the unfolded foldable segmented bed frame.
[0005] The preferred embodiment of the manually adjustable folding bath bed is that the guardrail has a segmented structure, each segment of which can be hinged to flip upwards and lock, forming a safety guardrail during bathing. When in use, the guardrail can be horizontally overlapped onto the bed at a 90° angle, providing a seamless connection to improve safety when the elderly are being pulled in. When folded downwards, it can be flush with the bed frame, and the upright guardrail can be flipped 180° to form a flat, embedded storage. The foldable segmented bed frame includes a first bed board, a second bed board, and a third bed board, which are connected by folding hinges. The first and third bed boards fold in opposite directions to the bed surface at 90°, which can prevent the bed surface from folding due to force. When the bed frame is folded, the guardrails flip down 180° and fold into the middle of the two sides of the bed board. When unfolded, they are fixed in an upright state by limiting buckles.
[0006] The preferred embodiment of the manually adjustable folding bath bed is that the scissor legs adopt an X-shaped cross hinge structure, connected by a pin in the middle, with a hinged caster at the bottom, and a slider and lead screw transmission at the top. The casters are silent swivel casters, and at least two casters have a brake locking function.
[0007] The preferred embodiment of the manually adjustable folding bath bed is that the matching bath tub is made of foldable soft waterproof material with hard edging, and is matched and fixed with the slots of the foldable segmented bed frame, forming a seamless bath tub space when unfolded; the edge of the matching bath tub is provided with a drain outlet for easy drainage after use.
[0008] The preferred embodiment of the manually adjustable folding bath bed is that the height adjustment range of the folding bath bed covers 350mm-750mm, which is suitable for the height of home beds, wheelchairs and nursing tables, and the crank is located on the side of the foot of the bed for easy operation.
[0009] The preferred embodiment of the manually adjustable folding bath bed is that the overall folding bath bed adopts an aluminum alloy frame, the key load-bearing components are reinforced, the net weight is ≤20kg, and it forms a rectangle of 750×920×200 after folding.
[0010] A method for assisting bathing with a manually adjustable and folding bath bed includes the following steps: Step 1: Unfold the folded bathing bed, adjust the bed height to be level with the elderly person's bed, and place the matching bathing tub; Step 2: Gently move the elderly person to the bathing bed using a sheet or transfer cloth; Step 3: Flip and lock the guardrail, then push the shower bed into the bathroom; Step 4: Perform the bathing procedure; Step 5: After bathing, drain the water, push the elderly person back to their original position, and then reverse the process to move the elderly person back to their original bed.
[0011] When folding, lower the bed to its lowest position, rotate the crank counterclockwise, the screw drives the slider to move outward, and the scissor legs fold to their minimum height to fit against the bed bottom; the third bed board flips down 90°, the first bed board flips down 90°, and at the same time the guardrail flips horizontally 180° and stacks it on the side of the bed; the third bed board and the first bed board are both perpendicular to the second bed board, and the three bed boards form a parallel stack after folding. Beneficial effects
[0012] This invention features a three-section folding bed frame with embedded guardrails for storage. When folded, it forms a rectangle measuring 750×920×200 mm, fitting easily into a car trunk. The aluminum alloy frame weighs ≤20 kg, allowing a single person to carry it upstairs using a ladder. The bed height is adjustable from 350mm to 750mm for elderly bed users, facilitating easy movement with bed sheets. The guardrails have no protruding parts when folded, preventing scratches during transport. The height adjustment range covers various scenarios including hospital beds, wheelchairs, and home care tables. The quick-release design of the washbasin allows it to be used as a medical examination bed.
[0013] This invention provides a technical infrastructure-level solution for home-based elderly care by systematically addressing the three major pain points of bathing equipment: "inability to transport, poor usability, and lack of safety". Attached Figure Description
