2. Description of the Related Art As a conventionally known mat of this type, a mat manufactured by Tarley, England, is well known under the trade name "ripple mat".

[0003]

In the above-mentioned known mat, the air cell has a frustoconical shape in which both ends are thick and the central portion is thin, so that the mattress is composed of a plurality of air cells. The contact area with the user becomes wider, and the body pressure can be dispersed or the contact place of the mattress can be changed, but the effect of rolling over cannot be expected. Therefore, an object of the present invention is to improve the shape of the air cell, and to provide the market with an air cell used for a floor-slip prevention mat that can automatically turn over a patient and can sufficiently exert a bed-shedding prevention effect.

[0004]

In order to solve the above-mentioned problems, the air cell used in the floor sore prevention mat of the present invention has a plurality of air cells adjacent to a flat base sheet in the transverse direction. The air cells are detachably provided at both ends, each air cell forms an elongated air chamber, and these air chamber groups are divided into at least two series, and air supply for supplying air to each system over time. In the air cell used for the mat for preventing bedsores connected to the device,
The air cells are in the shape of a truncated cone, and each end of the air cells is provided with a connection port that can be connected to an air supply tube. The air cells have a wide air chamber at one end and the other end. Is characterized in that the width becomes narrower. The air cell has a rubber or soft P inside layer.
The VC layer is preferably formed of a composite material having a cloth layer as an outer layer.

The operation of the invention described in claim 1 which is constructed as described above will be described below together with its usage. A predetermined number of air cells according to the present invention are arranged on a flat base sheet in the transverse direction so as to be removably attached to each other sequentially by adhering means such as male and female hooks so as to be adjacent to each other sequentially. Of the different side edges of the base sheet and the air supply tube arranged near the side edge of the base sheet is connected to a connection port in the air chamber of the air cell group via an appropriate connector or directly. Next, the two air supply tubes arranged along the both sides are connected to a common air supply source.

When it is desired to turn over a user who is a patient such as a bedridden elderly person by using the mat in which the air cell of the present invention is assembled in this way, for example, a common air supply source is used to pass one of the air supply tubes. When air is alternately supplied to the air cell group of the system, the air cell of one system swells first, the air cells of the other system remain flat, and the air chambers of each air cell in the one system that supplied air are respectively The ends of the base sheet on the same side are made wider so that they are thicker, and the ends of the mat on the other side are narrower because the width of the air chamber is narrower.
The mat as a whole is thick on one side and thin on the other side. Next, the air in one system to which air was supplied last time is exhausted from the air chamber of the air cell group, and the air is supplied to the air chamber of the air cell group in the other system in the same manner as the previous time. , It swells in a thickness shape that is the opposite of the last time.

By repeating the above-mentioned operation and alternately inflating and deflating the two series of air cell groups, the postures of the patient and the user on the mat are changed and they are turned over. When air is supplied to both air systems, all the air chambers of the air cell group in all of the mat swell, and as a whole, both sides of the mat are thick and the center swells slightly from the bedside to the feet. When any air cell is damaged during use and air leakage occurs, the supply of compressed air to the air cell group is stopped, only the damaged air cell is removed from the base sheet, replaced with a new one, and re-installed. use. Since the air cell in the invention described in claim 2 is made of a composite material having a rubber or soft PVC layer as an inner layer and a cloth layer as an outer layer, in addition to the above-mentioned action, damage due to air pressure is reduced. To do.
