Specifically, the partition plate is fixedly connected with the upper side wall and the lower side wall of the inner side of the base plate through a plurality of support columns.

Specifically, the upper connecting pipe is a negative pressure resistant steel wire hose, and the lower connecting pipe is a pressure resistant steel wire hose.

Specifically, the air outlet end of the air pump is provided with an air outlet one-way valve

Specifically, the elastic air bag is of a strip-shaped structure and is made of elastic rubber.

Specifically, the upper end of the insertion tube is flush with the upper end of the backing plate.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses, simple structure, convenient operation can adsorb disposable plastic paper fixedly through last sucking disc, prevents its and backing plate separation, and through setting up elastic airbag, elastic airbag aerifys the travelling comfort that the back patient lies on the chair cushion better, and elastic airbag restores under its elastic action and hugs closely the backing plate upper end when not using, and the backing plate upper end is more level and more smooth, consequently conveniently clears up the backing plate upper end.
