Description

Technical Field

[0001] This utility model relates to the field of medical and nursing supplies technology, specifically an inflatable memory foam turning pad. Background Technology

[0002] Positioning care for long-term bedridden patients is a crucial aspect of clinical nursing and a key measure in preventing complications such as pressure ulcers. Clinical statistics show that approximately 95% of paralyzed patients require a change of position every two hours, and this figure reaches over 65% for patients weighing over 80 kg. While tools such as tubular sheets, turning mats, or triangular side-lying pillows are available to assist with turning, their use in practice is often cumbersome, requiring frequent adjustments and involving complex, time-consuming procedures.

[0003] Therefore, there is an urgent need for a new type of turning assist device that can simplify the operation process, reduce the nursing burden, and improve patient comfort. Utility Model Content

[0004] The purpose of this invention is to provide an inflatable memory foam turning pad to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An inflatable memory foam turning pad includes a tubular sheet and a pair of inflatable air bladders. The tubular sheet has a cylindrical structure, is made of soft material, and has a smooth surface. The openings at the front and rear ends of the tubular sheet face the head and foot of the bed, respectively. The rear end of the tubular sheet is level with the patient's shoulder, and the front end is level with the patient's groin. The inflatable air bladders have a strip-shaped structure, with their length parallel to the length of the bed. The pair of inflatable air bladders are located on the upper surface of the upper layer of the tubular sheet. The end of the inflatable air bladder near the bed frame can extend and retract vertically, while the end of the inflatable air bladder near the center line of the bed, which is parallel to the bed frame, cannot extend and retract vertically. When inflated, the air bladders have a fan-shaped cross-section columnar structure.

[0007] Furthermore, each of the inflatable airbags is individually connected to an inflation / deflation tube. The end of the inflation / deflation tube away from the inflatable airbag is connected to an air valve. The air valve contains an air valve core and is connected to an air pump to inflate or deflate the inflatable airbag.

[0008] Furthermore, a row of straps is connected to the upper layer of the cylindrical sliding sheet near the two sides of the bed frame.

[0009] Furthermore, a row of hooks is provided on both sides of the bed frame, and the positions of the hooks and the pull straps correspond one-to-one. The hooks and pull straps are engaged and connected to the bed frame through the hook straps.

[0010] Furthermore, a baffle is rotatably connected to the opening position of the hook, and a torsion spring is installed between the inner walls of the hook and the inner walls of the hook.

[0011] Furthermore, multiple folds are provided on the front and rear sidewalls and the sidewall near the bed frame of the pair of inflatable airbags. The folds open when the airbags are inflated and fold up after the airbags are deflated. After the folds are folded up, the airbags return to their planar structure.

[0012] Furthermore, a pressure-reducing pad is connected to the upper sidewall of each of the pair of inflatable airbags. The edge of the pressure-reducing pad extends beyond the inflatable airbag, and the front and rear ends of the pressure-reducing pad are flush with the front and rear ends of the cylindrical slide.

[0013] Furthermore, the pressure-reducing pad is made of thin memory foam.

[0014] Furthermore, the cylindrical slide is made of nylon.

[0015] Furthermore, a soft and inelastic reinforcing mesh is embedded inside the cylindrical slide.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In use, this utility model simplifies the patient's turning process by allowing caregivers to easily roll the patient's body with a gentle pull. The expansion and contraction of the inflatable airbag reduces the need for caregivers to manually place the side-lying cushion, and provides greater stability and reliability. The cylindrical structure of the tubular sliding sheet, combined with its smooth surface, allows for easy patient movement, reducing the workload of caregivers. Through the synergistic effect of the tubular sliding sheet, inflatable airbag, and pull strap, this utility model not only simplifies the turning process but also significantly reduces the burden on caregivers, improving patient comfort and the efficiency of nursing care.

[0018] 2. In this utility model, the hooks are fixed to the bed frame by hook straps, and are hooked one-to-one with the pull straps to prevent the cylindrical sliding unit from shifting. A baffle is provided at the opening of the hook, and the baffle is automatically closed by a torsion spring to prevent the pull strap from falling off.

[0019] 3. In this invention, the pressure-reducing pad is connected to the upper side wall of the inflatable airbag, with its edges extending beyond the airbag's range. Both its front and rear ends are flush with the cylindrical sliding sheet, fully covering the patient's contact area. The pressure-reducing pad is made of thin memory foam, which can adaptively shape according to the patient's body curves, dispersing pressure and improving comfort. Attached Figure Description

[0028] 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.

[0029] Example 1: Please refer to Figures 1-7 An inflatable memory foam turning pad includes a tubular sheet 7 and a pair of inflatable airbags 10. The tubular sheet 7 is a cylindrical structure with a soft and smooth surface. The openings at the front and rear ends of the tubular sheet 7 face the head and foot of the bed 1, respectively. The rear end of the tubular sheet 7 is level with the patient's shoulder, and the front end of the tubular sheet 7 is level with the patient's groin. The inflatable airbags 10 are strip-shaped structures, with their length parallel to the length of the bed 1. The pair of inflatable airbags 10 are placed on the upper surface of the upper layer of the tubular sheet 7. The end of the inflatable airbag 10 near the bed frame 2 can extend and retract vertically, while the end of the inflatable airbag 10 near the center line of the bed 1 parallel to the bed frame 2 cannot extend and retract vertically. When inflated, the inflatable airbag 10 has a fan-shaped cross-section columnar structure.

[0030] Each inflatable airbag 10 is individually connected to an inflation / deflation tube 11. The end of the inflation / deflation tube 11 away from the inflatable airbag 10 is connected to an air valve 13. The air valve 13 contains an air valve core 14. The air valve 13 is connected to an air pump to inflate or deflate the inflatable airbag 10.

[0031] The upper layer of the tubular sliding sheet 7 is connected to a row of straps 8 near the two side bed sides 2.

[0032] Multiple folds 12 are provided on the front and rear side walls of a pair of inflatable airbags 10 and the side wall near the bed frame 2. The folds 12 open when the inflatable airbags 10 are inflated and fold up after the inflatable airbags 10 are deflated. After the folds 12 are folded up, the inflatable airbags 10 return to their planar structure.

[0033] The cylindrical slide 7 is made of nylon.

[0034] The cylindrical slide 7 has a soft and inelastic reinforcing mesh embedded inside.

[0035] Working principle of this embodiment:

[0036] In this embodiment, the patient lies flat on the tubular sheet 7 with the inflatable airbag 10 in a deflated state and the fold 12 folded up, restoring the airbag to its flat structure. The caregiver pulls the strap 8, utilizing the significant friction between the tubular sheet 7, the bed sheet, and the patient's body to roll the patient to one side, completing the turning motion. Furthermore, because the tubular sheet 7 is soft and smooth, and has a cylindrical structure, the friction between its upper and lower layers is relatively small, but the friction with the bed sheet and the patient's body is large. This allows the caregiver to easily move the patient left and right while they are lying on the tubular sheet 7, adjusting their sleeping position. After turning, the inflatable airbag 10 facing the patient's back is inflated through the air valve 13 and air pump connected to the inflation / deflation tube 11. After inflation, the airbag expands to form a fan-shaped cross-section columnar structure, and the fold 12 opens, supporting the patient's back and helping the patient maintain a stable lateral position. When it is necessary to return to the supine position, deflation is achieved through valve 13, and the inflatable airbag 10 returns to its flat structure, facilitating the next turning operation. The tubular slide 7 is made of soft and smooth nylon material, with an internal reinforcing mesh to enhance its strength and prevent it from tearing.

[0037] In this embodiment, the design of the pull strap 8 simplifies the patient's turning process by allowing caregivers to easily roll the patient's body with a gentle pull. The expansion and contraction function of the inflatable airbag 10 reduces the need for caregivers to manually place the side-lying cushion and provides greater stability and reliability. The cylindrical structure of the tubular slide 7, combined with its smooth surface, allows for easy movement of the patient's body, reducing the workload of caregivers.

[0038] This embodiment, through the synergistic effect of the tubular sliding sheet 7, the inflatable airbag 10, and the pull strap 8, not only simplifies the turning operation process but also significantly reduces the nursing burden, improves patient comfort, and increases the efficiency of nursing work.

[0039] Example 2: Please refer to Figures 1-4 An inflatable memory foam turning-over mattress differs from Embodiment 1 in that each of the two side bed frames 2 is provided with a row of hooks 4, the hooks 4 and the pull straps 8 are positioned one-to-one, the hooks 4 and the pull straps 8 are hooked together, and the hooks 4 are connected to the bed frame 2 through the hook straps 3.

[0040] A baffle 5 is rotatably connected to the opening of hook 4, and a torsion spring 6 is installed between the inner walls of hook 4.

[0041] In this embodiment, the hook 4 is fixed to the bed frame 2 by the hook strap 3, and is hooked one-to-one with the pull strap 8 to prevent the cylindrical sliding sheet 7 from shifting. A baffle 5 is provided at the opening of the hook 4, and the baffle 5 is automatically closed by the torsion spring 6 to prevent the pull strap 8 from falling off.

[0042] Example 3: Please refer to Figures 1-3 An inflatable memory foam turning pad, which differs from Embodiment 1, has a pressure-reducing pad 9 connected to the upper side wall of each of the pair of inflatable airbags 10. The edge of the pressure-reducing pad 9 extends beyond the inflatable airbags 10, and the front and rear ends of the pressure-reducing pad 9 are flush with the front and rear ends of the cylindrical sliding sheet 7.

[0043] The pressure-relief pad 9 is made of thin memory foam. In actual production, a memory foam pad thickness of about 5 cm is optimal.

[0044] In this embodiment, the pressure-reducing pad 9 is connected to the upper side wall of the inflatable airbag 10, with its edges extending beyond the airbag's range. Both its front and rear ends are flush with the cylindrical sliding sheet 7, fully covering the patient's contact area. The pressure-reducing pad 9 is made of thin memory foam material, which can adaptively shape according to the patient's body curves, dispersing pressure and improving comfort.
