Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to an air mat for changing the posture of a chronic bed-occupied patient, particularly a posture changing air mat for assisting in turning over.

<Prior art> For patients who cannot move their bodies by themselves, such as chronic bedridden patients, such as bedridden elderly and critically ill patients, nurses can prevent bedsores or keep them on their backs at all times. In order to prevent subsided pneumonia and the like, which are likely to be induced, the work of rolling over is performed at regular intervals, for example, about every 2 hours. These operations are labor-intensive for the caregiver and are often discomforting for the patient. In order to deal with such a problem, a device has been proposed in which an air mat is used for turning over and changing the lateral posture, for example (Japanese Utility Model Publication No. 52-55915).

<Problems to be Solved by the Invention> With the structure described in the above publication, the body of a patient can be tilted at a certain angle, but the tilt angle cannot be changed according to the medical condition of the patient or the weight of the patient. . Generally, it is desirable to increase the tilt angle for patients with mild disease and to decrease the tilt angle for patients with severe disease. Further, in a patient having a heavy weight, the air cell is crushed and the inclination angle becomes small, and conversely, in a patient having a light weight, the inclination angle becomes large. There is a problem that it is difficult to obtain a constant desired tilt angle.

The present invention has been made in view of such circumstances.

<Means for Solving the Problems> A body position changing air mat according to the present invention includes a first cell having an air supply / exhaust port at a front portion and a rear portion, and having an elongated shape in the front-rear direction, and the first cell and the longitudinal direction. A second cell having the same capacity and the same shape as the first cell, which is connected to the object at a predetermined interval and has an air supply / exhaust port at the front and the rear respectively, and an upper surface of the first cell. Part of the upper surface of the second cell, which has a smaller capacity than the first cell and has a supply / exhaust port in the front part and the rear part, respectively. A second auxiliary cell having the same capacity and the same shape as the auxiliary cell and having air supply / exhaust ports at the front and rear portions, first connecting portions formed before and after the first cell, and before and after the second cell. Each having a second connecting portion formed therein Is.

In addition, the posture changing air mat according to the present invention includes a plurality of posture changing air mats arranged in the front-rear direction to connect the first connecting portions and the second connecting portions of the air mats to each other. The air supply / exhaust port of the first cell of the other air mat adjacent to the air supply / exhaust port of the first cell is connected by an air pipe, and the air supply / exhaust port of the second cell of the one air mat and the other air mat of the other adjacent air mat are connected. The air supply and exhaust ports of two cells are connected by an air pipe.

The air supply and exhaust ports of the second auxiliary cell of the air mat are connected by an air pipe.

<Operation> The posture changing air mat is laid under the back and waist of the patient. If the condition is light or heavy, air is supplied to the first cell from the air supply / exhaust port of the first cell, the first cell is inflated, and the patient's body is lifted on the right side (or left side). Is inclined. On the other hand, if the medical condition is heavy or light weight, air is supplied to the first auxiliary cell from the air supply / exhaust port of the first auxiliary cell to inflate the first auxiliary cell, and the patient's body is placed on the right side (or left side). Lifted and body leans. The tilt angle at this time is smaller than the tilt angle due to the expansion of the first cells.

A plurality of posture changing air mats are connected via the first and second connecting members and are set to have a length according to the height of the patient. As a result, an unnatural twisting force is not applied to the patient's body, and a natural rolling motion is performed.
