Description

Technical Field

[0001] The present invention relates to the technical field of medical and nursing supplies, and particularly to an inflatable memory foam turning pad. Background Art

[0002] The body position care of long-term bedridden patients is an important link in clinical nursing work and also a key measure to prevent complications such as pressure sores. According to clinical statistics, about 95% of paralyzed patients need to change their body positions every 2 hours, and the proportion of patients weighing over 80 kg reaches more than 65%. Although tools such as tubular sliding sheets, turning pads, or triangular side-lying pillows have emerged on the market for assisting in turning care work. However, they need to be used in combination during actual operation, and the operation is extremely cumbersome. During actual use, the position needs to be frequently adjusted, the operation process is complex, and it takes a long time.

[0003] Therefore, there is an urgent need for a new type of turning assistance device that can simplify the operation process, reduce the nursing burden, and improve the comfort of patients. Summary of the Invention

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

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] An inflatable memory foam turning pad, comprising a tubular sliding sheet and a pair of inflatable airbags. The tubular sliding sheet is a cylindrical structure with a soft material and a smooth surface. The front and rear ends of the tubular sliding sheet open towards the head and the tail of the hospital bed respectively. The rear end opening of the tubular sliding sheet is level with the patient's shoulder, and the front end opening of the tubular sliding sheet is level with the patient's thigh root. The inflatable airbags are strip-shaped structures, and the length direction of the inflatable airbags is parallel to the length direction of the hospital bed. A pair of inflatable airbags are arranged on the upper surface of the upper layer of the tubular sliding sheet. One end of the inflatable airbag close to the bed rail can be telescoped up and down, and one end of the inflatable airbag close to the center line parallel to the bed rail of the hospital bed cannot be telescoped up and down. After inflation, the inflatable airbag is a fan-shaped cross-section columnar structure.

[0007] Further, each of the inflatable airbags is separately connected to a charging and discharging tube. The end of the charging and discharging tube far from the inflatable airbag is connected with a valve. A valve core is arranged inside the valve, and the valve is connected with an air pump to inflate or deflate the inflatable airbag.

[0008] Further, a row of pulling straps are respectively connected to the positions of the upper layer of the tubular sliding sheet close to the two bed rails.

[0009] Further, a row of hooks are arranged on both bed rails. The hooks correspond to the positions of the pulling straps one by one, and the hooks and the pulling straps are hung and matched. The hooks are connected to the bed rail through hook straps.

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

[0011] Further, a plurality of folding layers are provided on the front and rear side walls and the side wall close to the bed rail of the pair of inflatable air bags. The folding layers open when the inflatable air bags are inflated, and fold up after the inflatable air bags are deflated. After the folding layers fold up, the inflatable air bags return to a flat structure.

[0012] Further, a decompression pad is connected to the upper side walls of the pair of inflatable air bags. The edge of the decompression pad extends beyond the inflatable air bags, and the front and rear ends of the decompression pad are flush with the front and rear ends of the cylindrical sliding sheet.

[0013] Further, the decompression pad is made of a thin memory foam pad.

[0014] Further, the cylindrical sliding sheet is made of nylon material.

[0015] Further, a soft and inelastic reinforcing mesh is embedded inside the cylindrical sliding sheet.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. When the present invention is used, the nursing staff only needs to gently pull to drive the patient's body to roll, simplifying the turning operation process. The inflation and deflation functions of the inflatable air bags reduce the steps of the nursing staff manually placing the side-lying cushions, and are more stable and reliable. The cylindrical structure of the cylindrical sliding sheet and the smooth surface enable the patient's body to move easily, reducing the work intensity of the nursing staff. Through the synergistic effect of the cylindrical sliding sheet, the inflatable air bags and the pulling belt, the present invention not only simplifies the turning operation process, but also significantly reduces the nursing burden, improves the comfort of the patient and the efficiency of the nursing work.

Specific implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1: Please refer to Figures 1 to 7 , an inflatable memory foam turning pad, including a cylindrical sliding sheet 7 and a pair of inflatable airbags 10. The cylindrical sliding sheet 7 is a cylindrical structure with a soft material and a smooth surface. The opening directions of the front and rear ends of the cylindrical sliding sheet 7 face the head and the tail of the hospital bed 1 respectively. The rear port of the cylindrical sliding sheet 7 is flush with the patient's shoulder, and the front port of the cylindrical sliding sheet 7 is flush with the patient's thigh root; the inflatable airbag 10 is a strip-shaped structure, and the length direction of the inflatable airbag 10 is parallel to the length direction of the hospital bed 1. A pair of inflatable airbags 10 are arranged on the upper surface of the upper layer of the cylindrical sliding sheet 7. One end of the inflatable airbag 10 close to the bed rail 2 can be telescoped up and down, and one end of the inflatable airbag 10 close to the center line parallel to the bed rail 2 of the hospital bed 1 cannot be telescoped up and down. After the inflatable airbag 10 is inflated, it is a fan-shaped cross-section columnar structure.

[0030] Each inflatable airbag 10 is separately connected to an air charging and discharging tube 11. The end of the air charging and discharging tube 11 far from the inflatable airbag 10 is connected to an air valve 13. An air valve core 14 is arranged in the air valve 13, and the air valve 13 is connected to an air pump to inflate or deflate the inflatable airbag 10.

[0031] A row of drawstrings 8 is connected to each of the upper layers of the cylindrical sliding sheet 7 near the two side rails 2 of the bed.

[0032] A plurality of folding layers 12 are provided on the front and rear side walls of a pair of inflatable airbags 10 and on the side walls close to the side rails 2. The folding layers 12 open when the inflatable airbags 10 are inflated and fold up after the inflatable airbags 10 are deflated. After the folding layers 12 are folded up, the inflatable airbags 10 return to a planar structure.

[0033] The cylindrical sliding sheet 7 is made of nylon material.

[0034] A soft and inelastic reinforcing net is embedded inside the cylindrical sliding sheet 7.

[0035] Working principle of this embodiment:

[0036] When this embodiment is in use, the patient lies flat on the cylindrical sliding sheet 7. The inflatable airbags 10 are in a deflated state, the folding layers 12 are folded up, and the airbags return to a planar structure. The caregiver pulls the drawstring 8 by hand and drives the patient's body to roll to one side by using the large friction force between the cylindrical sliding sheet 7 and the bedsheet and the patient's body, thus completing the turning-over action. In addition, since the cylindrical sliding sheet 7 is made of soft and smooth material and has a cylindrical structure, the friction force between its upper and lower layers is small, but the friction force with the bedsheet and the patient's body is large. When the patient lies on the cylindrical sliding sheet 7, the caregiver can easily push the patient to move left and right to adjust the patient's sleeping position. After turning over, the inflatable airbag 10 on the side facing the patient's back is inflated through the air valve 13 and the air pump connected by the air charging and discharging pipe 11. After inflation, the airbag expands to form a fan-shaped cross-section columnar structure, and the folding layers 12 open to support the patient's back and help the patient stably maintain the lateral lying position. When it is necessary to return to the supine position, the inflatable airbag 10 returns to a planar structure by deflating through the air valve 13, facilitating the next turning-over operation. The cylindrical sliding sheet 7 is made of soft and smooth nylon material, and a reinforcing net is embedded inside, which improves the strength of the cylindrical sliding sheet 7 and prevents the cylindrical sliding sheet 7 from being torn.

[0037] Through the design of the drawstring 8 in this embodiment, the caregiver only needs to gently pull to drive the patient's body to roll, which simplifies the turning-over operation process. The expansion and contraction functions of the inflatable airbags 10 reduce the steps of the caregiver manually placing the lateral lying cushions and are more stable and reliable. The cylindrical structure of the cylindrical sliding sheet 7 and the smooth surface enable the patient's body to move easily, reducing the work intensity of the caregiver.

[0038] Through the synergistic effect of the cylindrical sliding sheet 7, the inflatable airbags 10 and the drawstring 8 in this embodiment, not only the turning-over operation process is simplified, but also the nursing burden is significantly reduced, and the comfort of the patient and the efficiency of the nursing work are improved.

[0039] Embodiment 2: Please refer to Figures 1 to 4, An inflatable memory foam turning pad, which is different from that of Embodiment 1 in that a row of hooks 4 are provided on both sides of the bed rail 2, the positions of the hooks 4 correspond to those of the draw straps 8 one by one, the hooks 4 are engaged with the draw straps 8 in a hanging manner, and the hooks 4 are connected to the bed rail 2 through hook straps 3.

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

[0041] In this embodiment, the hook 4 is fixed on the bed rail 2 through the hook strap 3 and is engaged with the draw strap 8 one by one, which can prevent the displacement of the cylindrical sliding sheet 7. A retaining piece 5 is provided at the opening of the hook 4, and the retaining piece 5 is automatically closed through the torsion spring 6 to prevent the draw strap 8 from falling off.

[0042] Embodiment 3: Please refer to Figures 1 to 3 , An inflatable memory foam turning pad, which is different from that of Embodiment 1 in that decompression pads 9 are connected to the upper side walls of a pair of inflatable air bags 10, the edges of the decompression pads 9 extend beyond the inflatable air bags 10, and the front and rear ends of the decompression pads 9 are flush with the front and rear ends of the cylindrical sliding sheet 7.

[0043] The decompression pad 9 is made of a thin memory foam pad. When actually manufacturing, the memory foam pad with a thickness of about 5 cm is preferably selected.

[0044] In this embodiment, the decompression pad 9 is connected to the upper side wall of the inflatable air bag 10, the edge extends beyond the range of the air bag, and the front and rear ends are flush with the cylindrical sliding sheet 7, comprehensively covering the patient contact area. The decompression pad 9 is made of a thin memory foam material, which can adaptively shape according to the patient's body curve, disperse pressure, and improve comfort.
