Description

Technical Field

[0001] The utility model relates to the field of surgical nursing, in particular to a turning-over auxiliary device for treating critically ill patients. Background Art

[0002] Prolonged bed rest can lead to various complications, including poor blood flow and bedsores. Therefore, patients who need to rest in bed for extended periods of time usually need to be turned over regularly to prevent complications. However, general surgery patients often find it difficult to turn over on their own after surgery and require assistance from a doctor or nurse. However, these patients are heavy, making direct turning difficult for doctors or nurses. Therefore, a turning aid for critically ill patients is needed.

[0003] A search revealed Chinese patent publication number CN213941261U, which discloses a turning aid device for surgical nursing. The device comprises a bed frame and a turning plate disposed on the left and right sides of the bed frame's upper surface. Drive mechanisms are symmetrically positioned at each end of the turning plate, one end of which is hinged within a placement slot. A placement frame is fixedly connected to the bottom of the bed frame, and hydraulic levers are symmetrically positioned at the left and right ends of the placement frame. The turning plate comprises a turning plate body and mounting slots symmetrically disposed at each end of the turning plate body. The drive mechanism comprises a rotating shaft and a driving belt disposed at each end of the rotating shaft. Two rollers are disposed within the rotating belt, and a drive motor is positioned on one side of the rotating shaft. This utility model employs a hinged hydraulic lever to drive the turning plate, thereby driving the patient's body for easy turning.

[0004] While this technical solution can conveniently help patients turn over, directly driving the bed board to flip over can cause significant damage to the mattress in long-term use. Furthermore, the bed board tends to fold during flipping, resulting in the corners not providing adequate support for the patient. For patients with fractures, this lack of support can interfere with the wound healing process. Therefore, a turning aid device for critically ill patients has been proposed to address these issues.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1-Figure 2 The utility model provides an embodiment of a turning assist device for treating critically ill patients, comprising a rest bed 1 for the patient to rest, with support frames 2 fixedly connected to the left and right sides of the rest bed 1, and two sets of support frames 2 fixed on each side of the rest bed 1, the two sets of support frames 2 are symmetrically arranged on the sides of the rest bed 1, and a rotating shaft 3 is rotatably connected inside the support frame 2, and a winding assembly is fixedly connected to the outer periphery of the rotating shaft 3, and the winding assembly is used to roll up the bed sheet, and the horizontal plane of the rotating shaft 3 is higher than the horizontal plane of the bed board of the rest bed 1. When the patient lies on the rest bed 1, the winding assemblies on both sides and the patient will form a V-shape with the bed sheet, and the rotating shaft 3 The front end is fixedly connected with a rotating bevel gear 4, and the front of the rotating bevel gear 4 is meshed with a transmission bevel gear 5. The rotating bevel gear 4 is much larger than the transmission bevel gear 5. The transmission bevel gear 5 needs to rotate multiple circles when the rotating bevel gear 4 rotates one circle, which reduces the force required for the doctor or nurse to rotate. The transmission bevel gear 5 is fixedly connected with a rotating assembly inside the transmission bevel gear 5. The rotating assembly is used to support and drive the transmission bevel gear 5 to rotate. The rotating assembly includes a handwheel 6 for easy rotation. The inner side of the handwheel 6 is fixedly connected to the inside of the transmission bevel gear 5. The outer periphery of the handwheel 6 is rotatably connected to a rotating bracket 7 that plays a fixed supporting role. The inner side of the rotating bracket 7 is fixedly connected to the outside of the rest bed 1.

[0032] Reference Figure 2-Figure 3 The support frame 2 is provided with a card slot 8, and the card slot 8 is slidably connected to a threaded column 9 that serves as a limit. The inside of the threaded column 9 is fixedly connected to a prism block 10. The outer periphery of the threaded column 9 is threadedly connected to a threaded rotating block 11. When the threaded rotating block 11 is rotated, the threaded rotating block 11 can drive the threaded column 9 to move back and forth along the inner wall of the threaded rotating block 11. The inner side of the threaded rotating block 11 is rotatably connected to a stopper 12 that presses down to limit the position of both sides of the bed sheet. The outer periphery of the threaded column 9 is slidably connected to the inside of the stopper 12, and a prismatic groove 13 is provided inside the stopper 12. The prismatic groove 13 is provided in two groups, and the two groups of prismatic grooves 13 are symmetrically arranged inside the stopper 12 front and back. The outer periphery of the prism block 10 is slidably connected to the inside of the prismatic groove 13. The prismatic groove 13 limits the prismatic block 10 to slide only back and forth along the inner wall of the prismatic groove 13. The prismatic groove 13 and the prismatic block 10 prevent the threaded column 9 from rotating with the threaded rotating block 11.

[0033] Reference Figure 1 and Figure 4The winding assembly includes a winding roller 14 for conveniently winding up the bed sheet. A fixed groove 15 is opened on the outside of the winding roller 14 for conveniently inserting and fixing the bed sheet. A sliding groove 16 is opened on the inside of the fixed groove 15. There are two groups of sliding grooves 16. The two groups of sliding grooves 16 are symmetrically arranged above and below the fixed groove 15. The inside of the sliding groove 16 is elastically connected to a clamping block 18 through a limit spring 17. When the clamping block 18 is not under force, the limit spring 17 will push the clamping block 18 to the middle of the fixed groove 15 to clamp the bed sheet for easy winding. One end of the limit spring 17 is fixedly connected to the inner side of the sliding groove 16. The limit spring The other end of 17 is fixedly connected to the inner side of the clamping block 18, and the outer periphery of the clamping block 18 is slidably connected to the inside of the sliding groove 16. The sliding groove 16 limits the clamping block 18 to slide up and down only along the inner wall of the sliding groove 16. The front and rear ends of the clamping block 18 are in contact with the inclined block 19. The inclined surfaces at the front and rear ends of the clamping block 18 match the inner inclined surface of the inclined block 19. When the inclined block 19 slides inward, the inclined block 19 will squeeze the upper and lower groups of clamping blocks 18 to both sides along the inclined surface to make them open. A sliding rod 20 for easy pressing is fixedly connected to the outside of the inclined block 19, and the outer periphery of the sliding rod 20 is slidably connected to the inside of the winding roller 14.

[0034] Working principle: When you want to turn the patient over conveniently, turn the threaded block 11 to make the threaded column 9 slide into the inside of the baffle 12, and remove one side of the baffle 12. At this time, turn the handwheel 6, and the handwheel 6 drives the transmission bevel gear 5 to rotate, and the transmission bevel gear 5 drives the rotating bevel gear 4 to rotate. The rotating bevel gear 4 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the winding roller 14 to rotate to roll up the bed sheet and straighten it. At this time, the bed sheet is rolled up in a V-shape with one side raised under the patient's pressure. At this time, turn the handwheel 6 on the raised side, and the handwheel 6 rolls up the bed sheet, so that the patient moves with the bed sheet due to friction. The bed sheet fits perfectly with the patient's body to provide support, so that one side of the body is raised. At this time, the nurse can use his hands to help the patient turn over, which is more convenient to use. When you want to conveniently fix the bed sheet on the winding roller 14, squeeze the slide bar 20 inward, and the slide bar 20 pushes the inclined block 19 inward to separate the clamping block 18 from top to bottom. At this time, stuff the bed sheet into the middle of the fixing groove 15, release the slide bar 20, and the limit spring 17 pushes the clamping block 18 inward to clamp the bed sheet, thereby conveniently fixing the bed sheet and preventing it from slipping after winding.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
