Description

Movable air cushion

Technical Field

The invention belongs to the technical field of mattresses, and particularly relates to a movable air cushion.

Background

In the field of the existing medical industry, the medical air cushion bed can help the skin of a patient to be necrotized due to long-time local compression, and can effectively reduce the occurrence of bedsore. When a bedridden patient needs to transfer or replace a bed after an operation or in an operation, the patient needs to be lifted and transferred by matching with the sliding pad, and the patient can be helped to ventilate the skin of the patient for the usual bedridden transfer of the patient, so that the cell necrosis caused by local compression is reduced. Among the prior art, there is an inflatable sliding mat, the bottom of which is provided with an exhaust hole, so that certain buoyancy can be generated when gas is exhausted from the exhaust hole, the friction coefficient of the bottom of the inflatable sliding mat is reduced, and the difficulty of lifting and transferring is reduced. Because the air exhaust holes of the inflatable sliding cushion need to be continuously exhausted to generate buoyancy, the air in the inflatable sliding cushion needs to be ensured to be sufficient during the transfer process of the bedridden patient.

Some technical schemes related to a movable air cushion also appear in the prior art, for example, a chinese patent, patent No. 2018100701137, the invention provides a movable air cushion, which comprises an inflatable cushion, a blocking cloth, a cleaning layer, an inflating nozzle and an inflating pump, wherein the inflatable cushion is in a hollow structure, the hollow structure forms an airtight cavity, and the lower surface of the inflatable cushion is provided with an exhaust hole in a penetrating way; the blocking cloth is arranged in the inflatable cushion and divides the airtight cavity into at least two air chambers; the cleaning layer is detachably covered on the upper surface of the inflatable cushion; the inflating nozzle is arranged on the inflating pad, the inflating nozzle is communicated with the airtight cavity, and the inflating nozzle limits the gas in the airtight cavity to flow outwards along the inflating nozzle in a single direction; the inflator pump is arranged on the inflation pad, and the output end of the inflator pump is connected with the inflation nozzle; the movable air cushion has good air tightness, effectively reduces the friction coefficient, is convenient to carry and inflate, and is clean and sanitary.

Although the air cushion in the above-mentioned technique has the gas tightness good, effectively reduce coefficient of friction, conveniently carry, aerify convenient and clean sanitary advantage, but when the patient size is heavier, ordinary air cushion this moment can't provide sufficient buoyancy because bottom exhaust is limited, thereby make the air cushion because of the great condition that can't easily remove of coefficient of friction of lower surface, simultaneously because the exhaust hole of air cushion bottom is in normally open state, after the air cushion just begins to use or finishes using, the inside some gas of air cushion can follow the exhaust hole outflow this moment, in order to make the air cushion can effectual work or carry out effectual support to the patient, need utilize the pump to last high strength aerify the air cushion this moment, thereby lead to the inside gas of air cushion and the waste of electric quantity, and be unfavorable for the air cushion to carry out stable effectual work.

In view of the above, the invention provides a movable air cushion, which is characterized in that a suspension plate is arranged in a cushion body and a blocking structure is arranged at an exhaust hole, so that the cushion body is easier and more stable in the transferring process, the situation that a patient is difficult to transfer due to a heavier body is reduced, the situation that gas in the cushion body runs off from the exhaust hole when the air cushion is not in operation is reduced, and the energy conservation and the rapidness of the cushion body in use are greatly improved.
