Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical auxiliary products, specifically to a fall-proof transfer flatbed. Background Technology
[0002] Existing patient beds, especially mobile beds used for patient transport, often only have side rails on the left and right sides to prevent patients from falling off. However, this ignores the problem of patients taking shortcuts by not lowering the side rails when getting in and out of bed, and getting out directly from the head or tail, which can lead to falls, slips, or rollovers.
[0003] In addition, the existing patient beds often have side flaps that are fixed at a 90° angle. When the patient is large, the flaps cannot be flipped up, which leads to these patients being pushed through various passageways without any protective measures, resulting in many accidental injuries and medical disputes. Utility Model Content

[0050] This invention can be implemented in many ways and has various embodiments, therefore specific embodiments are illustrated and described in the accompanying drawings. However, this is not intended to limit the invention to specific implementations, but should be understood to include all modifications, equivalents, and even substitutions that fall within the spirit and technical scope of this invention.
[0051] like Figure 1 As shown, this embodiment provides a fall-proof transport flatbed that can provide all-round protection for the patient's head and tail. It includes a patient bed body 100, side guardrails 200 and head and tail guardrails 300.
[0052] Among them, the side guardrails 200 are foldable or flip-up and are installed in pairs on both sides of the length of the patient bed.
[0053] The head and tail guardrails are 300mm in size and can be folded or flipped up. They are installed at the head and tail of the patient bed.
[0054] The specific structure for enabling the guardrail to be folded and flipped is as follows:
[0055] like Figure 1 As shown, another guardrail structure based on rotation to raise the railing is provided, which can be used as a side guardrail 200 and a head and tail guardrail 300. The side guardrail 200 is used as an example below.
[0056] The guardrail 200 includes a lower horizontal bar 221, an upper horizontal bar 222, several vertical bars 223 and a limit valve 224;
[0057] The lower crossbar 221 is fixed to the patient bed body by common methods such as welding, riveting, and screwing;
[0058] Several vertical bars 223 are arranged between the lower horizontal bar 221 and the upper horizontal bar 222, and are rotatably connected to the lower horizontal bar 221 and the upper horizontal bar 222 (e.g., rotating seats 2231 and 2232 are fixed on the lower horizontal bar 221 and the upper horizontal bar 222, and the ends of the vertical bars 223 are all shaped like rotating shafts. The rotating shafts are mounted on the rotating seats to realize the connection between the vertical bar shafts and the upper and lower horizontal bars). That is, during use, the user can stretch the flat guardrail into a baffle by holding the upper horizontal bar and moving it left and right.
[0059] The limit valve 224 is fixed on the upper horizontal bar 222 and located outside the outermost vertical bar 2233. It restricts the rotation of the rotation axis between the outermost vertical bar 2233 and the upper horizontal bar 222, thereby fixing the baffle in an upright state.
[0060] The limit valve 224, such as Figure 2As shown, it includes a pin 2241, an elastic restoring element 2242, and a fixing seat 2243;
[0061] The pin 2241 is movably connected to the fixed seat 2243. One end is directly opposite the rotating shaft 2334 of the vertical rod 2233. Its shape matches the rotating shaft 2234 (the rotating shaft 2234 between the vertical rod 2233 and the upper horizontal rod adjacent to the limit valve 224 has a limiting member 22341, which can be toothed as shown in the figure or hole-shaped). It can lock the rotating shaft 2234 so that it cannot continue to rotate. The other end has a handle.
[0062] When the vertical bar 2233 is perpendicular to the upper and lower horizontal bars, the limiting component 22341 is directly opposite the head end of the pin 2241.
[0063] The top plate 2244 is fixed to the middle or front part of the pin 2241, which is located between the front and rear fixed seats 2243. An elastic restoring element 2242 (such as a spring) is also provided between the top plate 2244 and the rear fixed seat 2243. When the handle is subjected to force and moves away from the fixed seat, the elastic restoring element is compressed, and the head of the pin 2241 separates from the rotating shaft 2234, no longer restricting its rotation. At this time, the entire guardrail can be opened and closed freely under the drive of the upper crossbar. When the handle is not subjected to force, the elastic restoring element returns to its original position, the top plate 2244 abuts against the fixed seat 2243, and the head of the pin abuts against the position of the limiting member 22341 on the rotating shaft, thereby limiting the rotation of the rotating shaft and keeping the guardrail in an upright state. If it is necessary to restore the unused state (i.e., the flat state), the handle is pulled again to release the rotating shaft and make the guardrail lie flat.
[0064] like Figure 3 As shown, another protective barrier structure based on hinges for flipping is provided, which can be used as a side guardrail 200 and a head and tail guardrail 300.
[0065] The guardrail 200 includes a hinge 211 and a guard plate 212;
[0066] One side of the hinge 211 is fixed to the patient bed body 100, and the other side is fixed to the protective plate 212. The fixing in this article refers to traditional fixing methods such as welding, riveting, bonding, and screwing.
[0067] The hinge 211 can be selected according to actual needs, with opening angles of 0-360°, 0-180°, or 0-90°, or multi-angle limiting hinges, such as 0°, 90°, and 180° limiting hinges.
[0068] The aforementioned protective plate 212 is flipped relative to the patient bed body 100 under the action of the hinge 211 to achieve the effect of a baffle.
[0069] Considering the issue that larger patients may not be able to raise the side rails, such as Figure 4 As shown, this embodiment provides a railing with an adjustable angle that is inclined, which can be used as a side guardrail 200 and a head and tail guardrail 300.
[0070] The adjustable guardrail 200 is tilted and includes a bearing 231, a guardrail 232, and a limiting component 233.
[0071] The bearing 231 is installed in pairs on the patient bed body 100;
[0072] The limiting component 233 is fixed to the patient bed body, on the outside of the bearing 231;
[0073] The bottom of the guardrail 232 is a rotating shaft 2321;
[0074] The rotating shaft 2321 is mounted on the bearing 231, and the rotation on the bearing achieves the effect of relative rotation of the guardrail relative to the side of the patient bed body.
[0075] like Figure 5 As shown, the limiting member 233 is used to limit the rotation of the rotating shaft, and it includes a pin 2331, an elastic restoring member 2332 and a fixing seat 2333;
[0076] The pin 2331 is movably connected to the fixed seat 2333, with one end facing the outer viewing surface 23211 of the rotating shaft and the other end having a handle 23311;
[0077] The pin 2331, facing the side of the rotating shaft 2321, is also provided with a top plate 23312 between itself and the fixed seat. The top plate 23312 and the elastic restoring member 2332 are used to compress the elastic restoring member when the handle is subjected to force and moves away from the fixed seat, and the top of the pin 2331 moves away from the outer viewing surface 23211 of the rotating shaft. When the handle is not subjected to force, the elastic restoring member returns to its original state, and the pin abuts against the rotating shaft to restrict its rotation. Its elastic restoring principle is similar to that of the above embodiment.
[0078] The outer surface 23211 of the rotating shaft has several annular through holes 23222. Different through holes correspond to different rotation angles. When the head of the pin 2331 is inserted into different through holes, the rotation of the rotating shaft can be limited, thereby fixing the guardrail at the target angle. Thus, when the patient's body size exceeds the range of the bed, the guardrail can be adjusted to tilted wings to support the patient and prevent accidents caused by inertia when the patient turns.
[0079] While the foregoing has focused on embodiments, these are merely illustrative and do not limit the invention. Those skilled in the art will understand that various modifications and applications not illustrated above can be made without departing from the essential characteristics of these embodiments. For example, the constituent elements specifically shown in the embodiments can be implemented through modifications. Furthermore, various differences related to such modifications and applications should be interpreted as being included within the scope of the invention as defined in the appended claims.
