Description

Technical Field

[0001] The utility model belongs to a device for preventing bedsores or helping patients turn over, such as the technical field of special mattresses used for this purpose, and specifically relates to a novel multifunctional bedsore-preventing air cushion suitable for prone ventilation treatment to prevent potential bedsore risks. Background Art

[0002] At present, the anti-bedsore air cushion related products on the market are:

[0003] (1) An anti-bedsore inflatable mattress, which is composed of a strip-shaped inflatable bag and can be placed flat on the bed. An air pump is used to inflate the air bag. After inflation, the air nozzle cap is plugged in tightly, and the mattress is fixed to the bed with a rope through the hole, and a bed sheet is placed on the mattress.

[0004] (2) Fluctuating inflatable anti-bedsore air cushion, which is composed of strip-shaped inflatable bags. The bags are divided into odd and even airways from top to bottom. Two groups of airways are cyclically inflated and deflated every 12 minutes. After the airways are inflated, they fluctuate, giving the air cushion the function of alternating massage, improving local pressure and air permeability.

[0005] (3) Spherical inflatable anti-bedsore air cushion, which is composed of regularly arranged spherical air bags and can be placed flat on a bed or chair. The spherical air bags can move in groups and can shift the position of supporting the body, thereby reducing and shortening the pressure and time on the surface of fixed parts of the body.

[0006] (4) Home medical nursing beds can use hand-cranked mechanical arms to adjust the inclination of the left and right bed boards to allow patients to turn over.

[0007] During long-term use of the above four conventional air mattresses, it will be found that the turning over airbags and the alternating inflatable massage airbags will experience varying degrees of wear and tear, resulting in poor turning over and alternating inflatable massage effects in the later stages of use.

[0008] The inventor applied for an invention patent in April 2017, with application number 201710284140X, and the patent name is a multifunctional inflatable nursing mattress, which includes: a frame for users to lie down; a turning assembly, which has a first turning airbag and a second turning airbag arranged symmetrically on the left and right; a suspension assembly, which has a bag body connected by multiple air paths and arranged along the length direction of the frame; a massage assembly, which has multiple massage airbags arranged along the width direction of the frame; a control box, which is independently arranged outside the frame, and is provided with a control circuit, and a first air pump, a second air pump, a first air path switch, and a second air path switch connected to the control circuit; the mattress is separated from gas and electricity, has no hard objects, is safer and more reliable, and has multiple working modes such as turning over, alternating support, massage, and assisted sleep through the setting and control of multiple airbags. Automatic turning over and alternating massage care can be directly realized through the mattress, which can effectively prevent the patient's body from being subjected to long-term pressure, promote the patient's blood circulation, and prevent bedsores, while reducing the cost of care and labor intensity.

The three-way valve Ⅰ13 is arranged on the side wall of the pressure relief pad 2, and the switch knob on the three-way valve Ⅰ13 extends out of the outer wall of the pressure relief pad. In this embodiment, the head support pillow 5 adopts a gel pillow. This structure is provided with a head lifting airbag 7 and a gel pillow. The head lifting airbag 7 can be used to avoid the patient's face from being suspended and stiff during the prone treatment course, especially when the prone treatment course lasts for 12-16 hours, or even more than 16 hours. The head lifting airbag can not only provide lasting support and adjust the patient's treatment head position, but also improve facial pressure.
