EMBODIMENT OF THE INVENTION Hereinafter, the form for implementing this invention is demonstrated based on drawing. 1 or 2 is a perspective view showing a cushion body according to the present invention. As shown in FIG. 1 or 2, the cushion body 10 comprises a plurality of ellipsoidal balls 11 housed in a stretchable bag 15. As shown in FIG. The plurality of balls 11 are housed in a bag 15 arranged in series or in parallel. The cushion body 10 shown in FIG. 1 has three balls 11 arranged in parallel. In the cushion body 10 shown in FIG. 2(a), three balls 11 are arranged in series in a bag 15 and housed therein. Such a cushion body 10 easily conforms to the body of a person receiving nursing care or rehabilitation using the cushion body 10, and can be easily positioned by being deformed into various shapes. In addition, it is possible to apply a weak correction force that does not cause pain for a long time.

The ball 11 is elliptical and hollow. Also, the ball 11 preferably has a length ratio of its long axis to its short axis of 1.5 to 2.0. The length of the minor axis should be 50-200 mm. Also, the ball 11 is preferably elastic and soft, and can be made of, for example, butyl rubber. The air pressure of the ball 11 is preferably 1-10 kPa. Also, as shown in FIG. 2(b), it is preferable that the surface of the ball 11 has a pattern 11a forming irregularities. This is because such a ball 11 is excellent in positional stability, and the cushion body 10 easily conforms to the body of the user.

The bag 15 can be made of elastic woven or knitted fabric. Knitted fabrics have the advantage of being easy to provide stretchability in the required size and direction. The shape of the bag 15 varies depending on the number of balls to be accommodated and how the balls are arranged. For example, it can be mountain-shaped as shown in FIG. . In the case of the mountain-shaped bag 15, an opening 15a for inserting and removing balls is provided, and it is preferable to provide a window 15b on the opposite side of the opening 15a. This makes it easier to put the ball in and take it out, and increases the positional stability of the ball. Further, the periphery of the opening 15a preferably has rubber elasticity and is reinforced.

When the shape of bag 15 is rod-like, opening 15a is provided at one end. A band 16 can close the opening 15a. In this case, the bag 15 preferably has a surplus length portion 15c so as to have extra space even when a predetermined number of balls 11 are accommodated. By adjusting the length of the extra length portion 15c to adjust the gap 15d between the balls, various positionings can be easily accommodated.

Also, the cushion body 10 according to the present invention can be formed by connecting a plurality of ellipsoidal balls 11 in series or in parallel with a ball connector 17, as shown in FIG. The ball connector 17 of this example is made of an elastic band. This connector-shaped cushion body 10 is preferable as a cushion body configured by connecting about two balls 11 in series or in parallel.
