Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a foldable and retractable limb lifting and turning device. Background Technology

[0002] In medical and home care settings, limb lifting and turning are core care needs for long-term bedridden patients (such as the elderly and frail, post-operative recoveries, and disabled individuals). Due to limited limb mobility, these patients require manual assistance from caregivers or the use of assistive devices to complete turning movements in order to prevent pressure sores, promote blood circulation, and improve respiratory patency.

[0003] Publication (Announcement) No.: CN215938033U A medical care assistive limb lifting and turning device, comprising: "a base plate, a resin insert plate disposed at the right end of the base plate, a plurality of guide rollers disposed on the upper surface of the resin insert plate, a turning support plate pivotally connected to the base plate, a plurality of anti-slip protrusions disposed on the upper surface of the turning support plate, an inflatable cushion layer connected between the turning support plate and the base plate, a folded layer disposed at the left end of the inflatable cushion layer, a deflation valve and an inflation pipe disposed on the inflatable cushion layer, and a foot-operated air pump connected to the inflation pipe." Its beneficial effects are: this utility model achieves assisted turning operation by lifting the base plate in conjunction with the turning support plate, the inflatable cushion layer provides the power for turning, and the foot-operated air pump makes the process easier, allowing medical personnel to operate it alone; However, existing technologies have shortcomings: most devices only achieve the function of turning over or lifting, and lack synchronous limiting design. During operation, patients are prone to body displacement due to the slipping of the bed sheet, which increases the risk of limb sprains and traction pain, making it difficult to meet the needs of safe care. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a foldable and retractable limb-assisted lifting and turning device, comprising a base plate and a turning plate hinged to the base plate, and a foot pump, wherein the output end of the foot pump is connected to an inflation tube, and one end of the inflation tube is provided with an expansion airbag connected between the base plate and the turning plate. A bottom groove is formed in the middle of the bottom end of the substrate. A connecting pipe extending to the inner end of the bottom groove is embedded in the wall of the inflation tube. Multiple sets of rotating rods are rotatably connected to the inner end of the bottom groove. Each adjacent rotating rod is fixedly connected to a Z-shaped lever. A protrusion is fixedly connected to the inner side of each Z-shaped lever. Two horizontal plates are fixedly connected to the inner wall of the bottom groove near the two adjacent Z-shaped levers. A compression airbag is fixedly connected between the two horizontal plates. A through pipe is provided between the compression airbag and the connecting tube. A fixing block is fixedly connected to the inner end of the bottom groove near the rotating rod. A torsion spring is provided between the fixing block and the rotating rod.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5 The present invention provides the following technical solution: Example 1: A foldable and retractable limb-assisted lifting and turning device includes a base plate 1, a turning plate 11 hinged to the base plate 1, and a foot pump 2. The output end of the foot pump 2 is connected to an inflation tube 21. One end of the inflation tube 21 is provided with an expansion airbag 22 connected between the base plate 1 and the turning plate 11. A first valve is provided on the inflation tube 21. An exhaust pipe with a valve is embedded in one side of the expansion airbag 22. A triangular resin insert plate 12 is fixedly connected to the front end of the base plate 1. A guide roller 13 is rotatably connected to the top surface of the resin insert plate 12. The top surface of the turning plate 11 is provided with multiple anti-slip protrusions. A handrail is fixedly connected to the edge of the top surface of the turning plate 11.

[0016] The first valve on the inflation tube 21 is used to control the amount and speed of inflation into the expansion airbag 22 and to adjust the flipping angle of the flipping board 11; the exhaust pipe with a valve on one side of the expansion airbag 22 is used to release the gas inside the airbag. The triangular resin insert plate 12 at the front end of the substrate 1 facilitates the insertion of the device under the patient's body and reduces insertion resistance; the guide roller 13 on the resin insert plate 12 further reduces the friction with the bed sheet during insertion through rolling friction. The anti-slip protrusions on the top surface of the turning board 11 increase the friction between the patient's body and the board surface, preventing slipping during the turning process; the handrails on the edge of the turning board 11 provide grips for the patient, enhancing body stability.

[0017] In use, place the base plate 1 flat on the bed surface. The device can be easily pushed under the patient using the resin insert plate 12. The guide roller 13 reduces friction during insertion, preventing traction on the patient's limbs. The patient lies flat on the base plate 1 and the turning board 11. The anti-slip protrusions on the top surface of the turning board 11 prevent the patient from sliding, and the handrails provide a grip for support. Close the exhaust valve, and the caregiver steps on the air pump 2 to inflate the expansion airbag 22 through the inflation tube 21. The expansion of the airbag pushes the turning board 11 to rotate around the hinge point, allowing the patient's limbs to be lifted and turned. Adjusting the first valve controls the inflation speed, thereby adjusting the turning angle. After turning, open the exhaust valve to release the gas from the airbag, the turning board 11 returns to its original position, and the device can be folded for storage, saving space.

[0018] Example 2: The technical solution of this example, which differs from that of Example 1, includes: a bottom groove 101 is provided in the middle of the bottom end of the substrate 1; a connecting pipe 24 extending to the inner end of the bottom groove 101 is embedded in the wall of the inflation pipe 21; multiple sets of rotating rods 3 are rotatably connected to the inner end of the bottom groove 101; Z-shaped levers 31 are fixedly connected to the walls of two adjacent rotating rods 3; protrusions 310 are fixedly connected to the inner sides of the two Z-shaped levers 31; two horizontal plates 33 are fixedly connected to the inner wall of the bottom groove 101 near the two adjacent Z-shaped levers 31; a compression airbag 34 is fixedly connected between the two horizontal plates 33; a through pipe 35 is provided between the compression airbag 34 and the connecting pipe 24; a fixing block 10 is fixedly connected to the inner end of the bottom groove 101 near the rotating rods 3; a torsion spring 32 is provided between the fixing block 10 and the rotating rods 3; the bottom end of the Z-shaped lever 31 is made of rubber; a second valve 25 is provided on the wall of the connecting pipe 24; and an air outlet pipe with a valve is provided on the connecting pipe 24.

[0019] Among them, the bottom of the Z-shaped lever 31 is made of rubber, which can increase the friction between it and the bed sheet; The second valve 25 on the connecting pipe 24 is used to control the inflation passage to the compression airbag 34, thereby enabling the lifting function to be started and stopped; the air outlet pipe with a valve on the connecting pipe 24 is used to discharge the gas inside the compression airbag 34.

[0020] When in use, to assist in lifting the patient's limbs and prevent slippage, first close the air outlet valve and open the second valve 25. The gas generated by stepping on the air pump 2 is diverted through the inflation tube 21 to the connecting tube 24, and then injected into the compression airbag 34 through the connecting tube 35. The compression airbag 34 expands between the two horizontal plates 33, pushing the protrusions 310 of the Z-shaped levers 31 on both sides, forcing the Z-shaped levers 31 to rotate outward around the rotating rod 3 (at this time, the torsion spring 32 is torsionally charged). At this time, the bottom end (rubber material) of the Z-shaped lever 31 tilts upward and pushes the sheet outward, pushing the edge of the sheet outward and tightening it, forming a lateral limit on the sheet under the patient, preventing the patient from slipping relative to the body weight during the lifting process.

[0021] After the operation is completed, the gas in the compressed airbag 34 is released by opening the air outlet valve. The torsion spring 32 returns to its original position, causing the Z-shaped lever 31 to retract into the bottom groove 101 without affecting the folding and storage of the device. Through the linkage design between the connecting pipe 24 and the compressed airbag 34, the "lifting-limiting" integrated operation is realized, improving the stability and safety of care.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
