Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, and in particular to a turning device for the care of elderly internal medicine patients. Background Technology

[0002] Geriatric diseases, also known as age-related diseases, refer to age-related illnesses that occur in the elderly and have their own characteristics. The elderly not only suffer from more diseases than young people, but also have their own characteristics. This is mainly because as people enter old age, the structure of human tissues further ages, the functions of various organs gradually become impaired, the body's resistance gradually weakens, the ability to move decreases, and the coordination function is lost. When the elderly are hospitalized in the internal medicine department, they have difficulty using their hands and feet, making it difficult to turn over. If they are not turned over in time, lying in one position for a long time can easily lead to problems such as pressure sores.

[0003] A search revealed that Chinese patent number CN216021781U discloses a turning device for nursing elderly internal medicine patients, including a base plate with welded side plates, a main lying plate welded to the upper surface of the side plates, a side lying plate hinged to one side of the main lying plate, a connecting rod provided on the upper surface of the base plate, a rotating shaft fixedly connected inside the connecting rod, a rotating rod connected to the connecting rod through the rotating shaft, and a threaded surface on the rotating rod.

[0004] The aforementioned public document states that when lifting the side-lying board to assist the patient in turning over, the side-lying board is mainly lifted by a rotating rod driving an adjusting rod and a push block on the adjusting rod. However, in actual application, since the push block is located on the side of the side-lying board, the main force point of the side-lying board when the push block initially lifts the side-lying board is on the lower side, not directly below it. Therefore, the initial resistance is too great. At the same time, when the push block pushes the side-lying board up, there is mainly hard friction between the two, and the friction force is relatively large, which makes the operation more difficult. Moreover, after long-term use, the structure of the hard friction part is prone to wear, which reduces the service life of the device.

[0005] To address the aforementioned problems, this application proposes a turning device for the care of elderly internal medicine patients. Utility Model Content

[0008] Two symmetrically distributed lifting mechanisms are installed below the movable plate. The lifting mechanisms are located inside the base, and a drive mechanism is connected through the center of the base, with the drive mechanism located between the two lifting mechanisms.

[0009] Preferably, the base has two slots at the top, and the fixing plate has two front-to-back distributed blocks fixedly connected to the bottom, the blocks being embedded in the slots.

[0026] Please see Figures 1-7 The technical solution provided by this utility model specifically includes the following embodiments:

[0027] A turning device for nursing elderly internal medicine patients includes a base 1, with a bed board 2 connected to the top of the base 1. The bed board 2 is composed of a fixed plate 21 and two movable plates 22, and the two movable plates 22 are respectively connected to both sides of the fixed plate 21 by hinges.

[0028] Two symmetrically distributed lifting mechanisms 4 are installed below the movable plate 22. The lifting mechanisms 4 are located inside the base 1. A drive mechanism 5 is connected through the center of the base 1 and is located between the two lifting mechanisms 4.

[0029] The base 1 has two slots 11 on its top, and the bottom of the fixing plate 21 is fixedly connected to two front and rear distributed blocks 23. The blocks 23 are embedded in the slots 11. The bed board 2 can be fixedly installed on the base 1 through the blocks 23 and the slots 11, while not affecting the auxiliary operation of the movable plate 22 to turn the patient over. It is also more convenient to disassemble and reassemble for later maintenance.

[0030] The lifting mechanism 4 includes a threaded rod 41, which is movably connected to the inside of the base 1 via a bearing seat. A sleeve 42 is threadedly connected to the outer end of the threaded rod 41. A top rod 43 is movably connected between the top of the sleeve 42 and the bottom of the movable plate 22 via a hinge seat. An end face gear 44 is fixedly connected to one end of the threaded rod 41. The lifting mechanism 4 also includes a transmission rod 45, which is movably connected to the inside of the base 1 via a bearing seat. A gear 46 and a bevel gear 47 are fixedly connected to both ends of the transmission rod 45, respectively. The gear 46 meshes with the end face gear 44.

[0031] When the movable plate 22 is lifted to assist the patient in turning over, only the drive mechanism 5 needs to drive the lifting mechanism on the corresponding side. During this process, the threaded rod 41 can be rotated by the bevel gear 47, the transmission rod 45, the gear 46, and the end face gear 44. Since the sleeve 42 is threadedly connected to the threaded rod 41 and is also restricted by the connection of the top rod 43, the sleeve 42 can only move along the threaded rod 41 and will not rotate with it. When the sleeve 42 moves, the movable plate 22 can be lifted by the top rod 43, so that the patient's side can be lifted up and turned over. During this process, there is no hard friction between the movable plate 22 and the parts, so the driving difficulty is small, the wear is low, and the service life is longer.

[0032] The driving mechanism 5 includes a driving rod 51, with two support seats 53 sleeved on the outer end of the driving rod 51. The support seats 53 are fixedly connected to the inside of the base 1. The driving rod 51 is movably connected to the inside of the base 1 through the support seats 53. A double-sided bevel gear 52 is fixedly connected to the outer end of the driving rod 51. The double-sided bevel gear 52 is located between multiple bevel gears 47. Rotary wheels 54 are fixedly connected to both ends of the driving rod 51.

[0033] The drive mechanism 5 is symmetrically arranged, so it can be operated from both ends. It can be driven by simply controlling its left or right movement so that the double-sided bevel gear 52 meshes with the corresponding bevel gear 47.

[0034] The base 1 has storage slots 12 on both sides. The drive rod 51 is located inside the base 1 and extends into the storage slot 12. The rotating wheel 54 is located inside the storage slot 12. When no drive is needed, the rotating wheels 54 at both ends of the drive mechanism 5 are hidden in the storage slot 12, so they will not protrude and cause any problems. When in use, you only need to pull or push the drive mechanism 5 to one end and then rotate the rotating wheel 54 to perform the drive operation.

[0035] Two cross brackets 3 are fixedly connected inside the base 1. The top of the cross brackets 3 contacts the bottom of the bed board 2. The cross brackets 3 inside the base 1 can cooperate with the bed board 2 to support it, so that the bed board 2 has better support when in use.

[0036] Working principle:

[0037] When in use, a soft pad can be placed on the bed board 2. When it is necessary to assist the patient to turn over, the rotating wheel 54 can be held and the drive rod 51 can be pushed or pulled to one side. When the drive mechanism 5 moves to the left, the lifting mechanism 4 can be used to drive the movable plate 22 on the left side to be lifted, so that the patient can turn over to the right. Conversely, turning over to the left is the opposite.

[0038] When the rotating wheel 54 is held and the drive rod 51 is pulled to the left, the rotating wheel 54 is pulled out from the storage slot 12. At this time, the double-sided bevel gear 52 will move with the drive rod 51 and contact and mesh with the bevel gear 47 in the lifting mechanism 4 at the bottom of the left movable plate 22. Then, the drive rod 51 is rotated by the rotating wheel 54, and then the double-sided bevel gear 52 is meshed with the adjacent bevel gear 47 for transmission. Then, the threaded rod 41 is rotated by the transmission rod 45, the gear 46 and the end face gear 44. When the threaded rod 41 rotates, it can drive the sleeve 42 to move along the threaded rod 41. Then, the movable plate 22 can be lifted by the top rod 43. At this time, the left half of the patient's body is lifted by the movable plate 22 so that he can turn to the right.

[0039] When the patient needs to turn to the left, simply move the drive mechanism 5 to the right and continue with the above steps. During this time, the operator can operate from either side of the bed. When there is no need to turn the patient over, the drive mechanism 5 can be pushed in the center so that both wheels 54 are hidden in the storage slot 12. At this time, the double-sided bevel gear 52 does not contact any of the bevel gears 47, and even if it is rotated again, it will not have any effect.
