[0034] Bed sheets are a common tool in people's daily life, and people often change and wash them. However, due to the large flow of medical personnel in medical departments, different individuals use medical beds in outpatient wards and examination rooms frequently, which makes medical bed sheets relatively special. In addition, some diseases can be transmitted through physical contact, which will trouble every medical staff and patient.

[0035] In the related art, there is a problem of deviation or the bed sheet gathers toward the center and wrinkles during the process of pulling the bed sheet, which still requires medical personnel to assist in the replacement, resulting in low working efficiency of the bed sheet changing device.

[0036] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a device for changing bed sheets. When the bed sheet 14 needs to be replaced, it is only necessary to release the bed sheet 14 near the end of the bed, and then roll up the old bed sheet through the recycling drum 12. The splint 25 at the head of the bed clamps the bed sheet 14 and moves it to the end of the bed through the moving component 21, so that the new bed sheet 14 can remain flat while being pulled out. At the same time, the splint 25 at the end of the bed is moved to the head of the bed through the moving component 21, and the new bed sheet 14 is clamped and fixed.

[0037] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0039] When in use, the side of the bed sheet 14 is pulled and placed into the fixing frame 23, and then the first threaded rod 24 is rotated. The rotating first threaded rod 24 drives the clamping plate 25 to clamp and fix the side of the bed sheet 14 in the fixing frame 23 to prevent the bed sheet 14 from being displaced when the patient moves on the bed. When the bed sheet 14 needs to be replaced, the fixation of the bed sheet 14 near the end of the bed is released, and then the old bed sheet is rolled up through the recycling drum 12. The clamping plate 25 at the head of the bed clamps the bed sheet 14 and moves it to the end of the bed through the moving component 21, so that the new bed sheet 14 can remain flat while being pulled out. At the same time, the clamping plate 25 at the end of the bed is moved to the head of the bed through the moving component 21, and clamps and fixes the new bed sheet 14, which increases the convenience when replacing the bed sheet 14, reduces the workload of medical staff, and improves the working efficiency of the bed sheet changing device.

When the old bed sheet is rolled up, the rotating rod 123 is driven by the motor 122 to rotate, the old bed sheet is wound and rolled up, and the new bed sheet is pulled out from the replacement drum 13 at the same time.

[0045] In some embodiments, a transmission length sensor 27 is provided at both ends of the bed 11 and is located on one side of the bed sheet 14. When the transmission length sensor 27 detects that the length of the new bed sheet 14 is pulled out to a predetermined value and is covered on the bed 11, the motor is turned off.

[0046] Specifically, the model of the transmission length sensor 27 is DX-25B.

[0047] Specifically, the transmission length sensor 27 controls the switch of the motor through the PLC controller.

[0048] In some embodiments, a sealing door 15 is provided on the recovery drum 12 and the replacement drum 13 , and the sealing door 15 facilitates the collection and placement of the bed sheets 14 in the recovery drum 12 and the replacement drum 13 .

[0049] In some embodiments, a slider 34 slides on the outer side of the bed board, a vertical plate 31 is arranged on the top of the slider 34, the inner side wall of the vertical plate 31 is rotatably connected to a screw rod 35, the outer side wall of the screw rod 35 is threadedly connected to a placement plate 32, a slide groove 36 is provided on one side of the placement plate 32, and the placement plate 32 is slidably connected in the slide groove 36; a bevel gear 2 39 is arranged at the bottom of the screw rod 35, a shaft 37 is arranged on the inner side wall of the gear 211, the shaft 37 is rotatably connected to the bed board, one end of the shaft 37 is connected to a bevel gear 1 38, and the bevel gear 1 38 can be meshed and connected with the bevel gear 2 39.

[0050] Specifically, both sides of the bed board are provided with sliding grooves that match the slider 34. When changing the bed sheet 14, the two bevel gears can be connected together. Through the rotation of the gear 211, the bevel gear 1 38 is driven to rotate, and then the bevel gear 2 39 is driven to rotate, thereby driving the screw 35 to rotate. At this time, the placement plate 32 moves up or down on the vertical plate 31. When it moves to the appropriate position, the slider 34 can be slid to separate the two bevel gears, so as to facilitate the adjustment of the height of the pillow on the placement plate 32 to suit the use of different patients, and also avoid the influence of the pillow following the movement when changing the bed sheet 14. The entire placement plate 32 can also be moved to the middle position of the bed board and adjusted to a certain height for the convenience of patients to dine. When the placement plate 32 moves to the lowest position, it can press the gap between the hospital bed 11 and the bed board to limit one side of the bed sheet.
