The present invention relates to a mat which forms an elongated air chamber, and the air chamber groups are divided into at least two series, and each system is connected to an air supply device that supplies air over time.

[0002]

2. Description of the Related Art As a conventionally known mat of this type, a mat manufactured by Tarley, UK is well known as a product name "ripple mat".

[0003]

In the above-mentioned known mat, since the shape of the air cell is formed in a truncated cone shape having a narrow central portion, a mattress consisting of a few sub-air cells and a user The contact area is increased and the body pressure can be dispersed or the contact place of the mattress can be changed, but the effect of turning over cannot be expected. Therefore, an object of the present invention is to improve the shape of the air cell, to automatically turn over the patient, and to provide a mat that can sufficiently exert the bed sore prevention effect.

[0004]

In order to achieve the above object, the mat for preventing bedsores of the present invention is provided with a plurality of air cells detachably provided adjacent to a flat base sheet in the transverse direction. , Each air cell forms an elongated air chamber, and these air chamber groups are divided into at least two series, and in a mat connected to an air supply device that supplies air over time for each system, The plurality of air cells are formed into two series as a whole by making the series the same every other series, and the air is piped along the side edges of the base sheet which are different side edges of the base sheet for each series. The tube is connected to a supply tube via a T-shaped connector, the tube communicates with a common air supply source, and the air cells of each series are different from each other in one side edge of the base sheet. In the air chamber Wherein the width enough to become the other side edge thicker is are to thin form. It is preferable that the width of the narrower end of each air chamber is wider than that of the most narrowed portion. The width of the thicker end of each of the air chambers is 1.5 to 4 times the width of the thinnest part to maximize the rolling over effect. The air cell is preferably formed of a composite material having a rubber or soft PVC layer as an inner layer and a cloth layer as an outer layer. The air cell may be a rubber tube covered with a cloth bag.

[0005]

The operation of the present invention, which is constructed as described above, will be described below together with the method of use. A predetermined number of air cells in a transverse direction on a flat base sheet are removably attached adjacent to each other by attaching and detaching means such as male and female hooks, and different side edges of the base sheet for each series and the base sheet The air chamber of the air cell group is connected to the air supply tube arranged along the side edge via a T-shaped connector. Next, the two air supply tubes piped along the both side edges are connected to a common air supply source. By using the mat of the present invention assembled in this way, when wanting to turn over a patient such as a bedridden elderly person, the user, for example, from a common air supply source through one air supply tube to the air cell group of each system When air is alternately supplied to the first system, the air cells of one system swell and the air cells of the other system remain flat, and the air chambers of the air cells of the one system that supplied air are respectively on the same side of the base sheet. Since the ends of the mat are wide, they become thicker, and the other side of the mat bulges thinly because the width of the air chamber is narrowed, and the mat as a whole swells on one side and thinly on the other side. Then, the air in one system to which air was previously supplied is exhausted from the air chambers of the air cell group, and the air is supplied to the air chambers of the air cell groups in the other system in the same manner as the previous time. The group bulges into a thickness shape that is the opposite of the last time. By repeating such operations and alternately inflating and contracting the two series of air cell groups, the postures of the patient and the user on the mat are changed and the patient is turned over.
Further, 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 central part swells slightly from the bedside to the feet. In the case where the width of the narrow end of each air chamber is formed wider than the most narrowed portion, even when air is supplied only to the air chamber group of one system, The thin tip of each air chamber also bulges slightly thicker. When any air cell is damaged during use and air leakage occurs, the supply of pressurized 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. When the air cell is formed by covering a rubber tube with a cloth bag, liquid such as water or hot water is supplied to and discharged from the air cell by using an underwater pump to expand and contract the air cell. ..
