[0026] The utility model will be described below in detail with reference to the accompanying drawings Figures 1 to 3 And combining with the embodiment, the utility model discloses a kind of improved manual over-bed.

[0027] Overall, the utility model relates to a kind of improved manual over-bed, it includes symmetrically arranged bottom plate 1, the top surface of bottom plate 1 is fixedly provided with the sliding column 101 of top arc shape, the top of sliding column 101 is equipped with the matching and slidingly connected with its top arc and the interface 2, the top of interface 2 is equipped with the connecting groove 201, the connecting groove 201 is rotatably connected with the rotating shaft 4, the one end of rotating shaft 4 is rotatably connected with the inner side wall of connecting groove 201, the other end is from the other side and is sleeved with torsion spring 401 and is exported to the outside of interface 2, one end of torsion spring 401 is fixedly connected with the outer side wall of interface 2, the other end is fixedly connected with the end of rotating shaft 4;Rotating shaft 4 is fixedly connected with the extension rod 301, and the extension rod 301 is in the connecting groove 201, and the top end is fixedly connected with the fixed block 3, and the fixed block 3 between the two sides is fixedly provided with the receiving plate 5.

[0028] In the embodiment, the interface 2 is slidably connected on the sliding column 101, which can drive the receiving plate 5 to be slidably connected, and the patient is transferred from the hospital bed to realize bed changing, so that the receiving plate 5 is prevented from being blocked by the contact with the hospital bed. In addition, the receiving plate 5 is rotatably connected on the interface 2 through the rotating shaft 4, so that the receiving plate 5 can be inclined to form a slope, which is convenient for the patient to move to the receiving plate 5 or move out of the receiving plate 5, and prevents the patient from being injured again during the bed changing process.

[0029] It should be noted that the torsion spring 401 can drive the receiving plate 5 to be reset after being inclined, so as to prevent the patient from sliding off the receiving plate 5 when the receiving plate 5 is in an inclined state.

[0030] As preferred, the bottom of the connecting part 2 is preferably clamped with the top of the sliding column 101, facilitating disassembly while not affecting the sliding connection of the connecting part 2 on the sliding column 101.

[0031] In actual implementation, the bottom plate 1 is placed horizontally between two beds, the patient turns on his side, the limiting part drives the receiving plate 5 to slide to the back of the patient, and the receiving plate 5 is inclined by pressing one side of the receiving plate 5, facilitating the patient to lie on the receiving plate 5. After the patient lies on the receiving plate 5, the receiving plate 5 is manually righted by the torsional spring 401, so that the patient is stably laid on the receiving plate 5. Then, the connecting part 2 drives the receiving plate 5 to slide to the other bed, and after the patient is sent to the designated position, the other side of the receiving plate 5 is pressed to incline the receiving plate 5 in the opposite direction, so that the patient can smoothly slide along the slope of the receiving plate 5 to the bed, realizing the bed changing work.

[0032] Based on the above setting, in order to facilitate the quick disassembly of the receiving plate 5 on the connecting part 2 and facilitate the storage of the whole device, in the embodiment, as shown in Figure 2 and Figure 3 , the fixed blocks 3 and the receiving plate 5 are connected through a connecting assembly, and the connecting assembly includes fixed grooves 302 and bolts 303. The fixed grooves 302 are respectively arranged on the opposite sides of the two fixed blocks 3, the two sides of the receiving plate 5 are inserted into the fixed grooves 302, and the receiving plate 5 is fixedly connected with the fixed blocks 3 through the bolts 303.

[0033] In actual use, the two fixed blocks 3 need to be aligned and parallel to ensure the stability of the receiving plate 5 after installation. In addition, the receiving plate 5 is preferably made of polypropylene material, and when the side of the receiving plate 5 enters the fixed groove 302, the bottom end of the bolt 303 abuts against and presses the receiving plate 5, thereby fixing the receiving plate 5. Two bolts 303 are preferably arranged on each side to ensure the stability of the receiving plate 5.

[0034] As a preferred structure of the utility model, in the embodiment, as shown in Figure 1 , a friction surface 501 is fixedly arranged on the top surface of the receiving plate 5, which can increase the friction between the patient and the top surface of the receiving plate 5, preventing the patient from slipping during the sliding switching of the bed. As preferred, the friction surface 501 is preferably a rubber surface.

[0035] Based on the above setting, in the embodiment, in order to facilitate the operator to slide the receiving plate 5 more conveniently and avoid pushing and pulling the patient, causing discomfort to the patient, in the embodiment, as shown in Figure 1 , a plurality of buckles 502 are fixedly arranged on the top surface edge of the friction surface 501. In actual implementation, the receiving plate 5 is slid by pulling the buckle 502, realizing the bed changing of the patient. As preferred, the buckle 502 is a high-strength nylon rope.

[0036] In addition, in order to further prevent the patient from slipping on the receiving plate 5, in the embodiment, as shown in Figure 1 The friction surface 501 is symmetrically provided with air bags 503 on the top surface of both sides. After the patient is switched to the receiving plate 5, the patient is located in the middle of the air bags 503 on both sides, which can prevent the patient from slipping on the receiving plate 5.

[0037] In addition, in the embodiment, as shown in Figure 1 and Figure 3 The top surface of the connecting part 2 is symmetrically connected with a limiting block 6 in sliding mode, the limiting block 6 is located on both sides of the fixed block 3, and the top surface is in abutment with the bottom surface of the receiving plate 5. The limiting block 6 can limit the receiving plate 5, so that the receiving plate 5 is prevented from tilting due to the weight of the patient being too large and exceeding the limiting range of the torsion spring 401 when the receiving plate 5 is transported. When it is necessary to tilt the receiving plate 5, the limiting block 6 can be slid out of the connecting part 2.

[0038] The above only describes the preferred embodiment of the utility model, and does not limit the utility model, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
