Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary devices, in particular to a bed turning auxiliary device. Background Art

[0002] Nursing home beds are specially designed for the elderly. Most nursing home beds have adjustment functions, that is, they can adjust the position of the back and legs so that the elderly can sit up or lift their legs. Refer to the nursing bed with patent publication number: CN108378999A. Nursing home beds are mostly made of metal and plastic materials, and the bed body is mostly sprayed with medical coatings to provide additional hygienic protection and easy cleaning capabilities for the bed body.

[0003] When there are elderly people who are unable to move or have difficulty in moving lying on the bed, they are prone to pressure sores if they stay in bed for a long time. When the elderly need to be medicated and wiped on the back, they need to be turned over. However, when turning over the elderly, most of the existing methods use manual force on the elderly's body to drive the elderly to turn over, which is quite laborious. When encountering an elderly person who cannot be touched (contagious through contact with the body surface), it is necessary to wear protective clothing and then touch the elderly to turn them over, which is quite cumbersome. In order to solve the above-mentioned problems, a bed turning assist device is provided. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example

[0018] See also Figure 1-4 This embodiment provides a bed turning assistance device, including a bed frame and a fixing plate 1.

[0019] Specifically, the fixing plate 1 is fixedly connected to the upper end of the bed frame, such as Figure 2 As shown, rotating plates 2 are hinged on both sides of the fixed plate 1.

[0020] In order to conveniently control the rotation of the rotating plate 2, a rotating mechanism 3 and a linkage mechanism 4 are provided in the bed frame.

[0021] Specifically, the rotating mechanism 3 includes a connecting rod 31, a pull rod 32 and a driven gear 33, wherein the driven gear 33 is rotatably mounted in the bed frame, and one end of the pull rod 32 is rotatably connected to the edge of the end surface of the driven gear 33, as shown in FIG. Figure 2 As shown, a support rod 21 is fixedly connected to one end of the rotating plate 2 below the fixed plate 1 , one end of the connecting rod 31 is rotatably connected to the lower end of the support rod 21 , and the other end of the connecting rod 31 is rotatably connected to the other end of the pull rod 32 .

[0022] like Figure 4 As shown, the lower end of a single rotating plate 2 is fixedly connected to two support rods 21, that is, a rotating mechanism 3 with two rotating support rods 21 is installed in the bed frame. Of course, the support rods 21 and the rotating mechanism 3 are not limited to two. Theoretically, the more the number, the more stable the rotation of the rotating plate 2.

[0023] Specifically, two linkage mechanisms 4 are provided, the two linkage mechanisms 4 are symmetrically arranged, and the two linkage mechanisms 4 are respectively located below the two rotating plates 2 .

[0024] The linkage mechanism 4 includes a rotating rod 41, a driving gear 42 and a rocker 43, wherein the rotating rod 41 is rotatably mounted in the bed frame, and two driving gears 42 are provided, and the two driving gears 42 are fixedly sleeved on the outer wall of the rotating rod 41. Figure 4 As shown, the two driving gears 42 are meshed with the two driven gears 33 respectively. Figure 1 As shown, the rocker 43 is rotatably mounted on the end surface of the bed frame, and one end of the rotating rod 41 passes through the outer wall of the bed frame and is fixedly connected to the rocker 43. Rotating the rocker 43 can drive the rotating rod 41 to rotate.

[0025] The fixed plate 1 and the rotating plate 2 form a bed board. When an elderly person lies on the bed board and needs to be turned over, the rocker 43 is rotated to rotate the rotating rod 41 and the driving gear 42. The driving gear 42 rotates to drive the driven gear 33 to rotate, that is, the pull rod 32 is driven to rotate synchronously. The pull rod 32 rotates to pull one end of the connecting rod 31, and the connecting rod 31 pulls one end of the support rod 21, driving the support rod 21 to rotate, that is, the rotating plate 2 is driven to rotate through the lever principle, and the rotating plate 2 can drive the elderly person at the upper end of the bed board to turn over.

[0026] like Figure 4 As shown, the diameter of the driving gear 42 is much smaller than the diameter of the driven gear 33. Compared with directly rotating the driving gear 42, the driving gear 42 is driven to rotate by the driven gear 33, which increases the torque, improves the transmission efficiency, reduces the rotation speed of the driving gear 42, and prevents the rotating plate 2 from flipping too fast.

[0027] In order to make the elderly lying on the bed more comfortable, a mattress 5 is fixedly installed on the bed board composed of the fixed plate 1 and the rotating plate 2.

[0028] like Figure 1 As shown, the upper end of the mattress 5 is provided with two indentations, and the rotating connections between the fixed plate 1 and the two rotating plates 2 are aligned with the two indentations respectively, so that the mattress 5 is folded when the rotating plate 2 rotates.

[0029] When the elderly person needs to turn over to the right side, he needs to rotate the rotating plate 2 on the left side. At this time, the rotating plate 2 on the left side will exert a thrust on the elderly person, causing the elderly person to easily slide from above the rotating plate 2 on the right side. Therefore, when the elderly person needs to be turned over, the right rotating plate 2 can be rotated first to make the right rotating plate 2 slightly rotate and tilt to prevent the elderly person from sliding, and then the left rotating plate 2 can be rotated to make the elderly person turn over to the right side.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
