Using method and operation principle are as follows: backboard and seat are tilted, patient can with the hands rotate the handwheel that is positioned at a both sides, driving shaft is rotated, small conical gear on the driving shaft drives large conical gear and driven screw rod rotates, integral nut on the driven screw rod moves toward head of a bed direction, tilt in 0 °～90 ° scopes by the relative horizontal direction of pivoted arm pulling backboard, the seat that pulling is simultaneously floated is a rake angle before fulcrum tilts accordingly with the supporting arm on the bedstead side panel, calf plate also produces corresponding top rake, at this moment patient needs the words of defecation, buttocks can be moved on the pit of seat, naturally and understandably aim at defecating hole, comfortable ground defecation.

Compared with the prior art, this utility model has following characteristics:

1, easy to operate.As long as disposable rotation handwheel can be realized the interlock of backboard and seat.

2, use is comfortable.Patient can be adjusted to sleep positions and the defecation position of feeling happy most voluntarily.In addition, corresponding top rake appearred in rake angle, calf plate before the seat that floats produced, and also satisfied patient's physiological function needs.

3, alleviate nursing staff's labor intensity, do not need the nursing staff at every moment to keep at one's side patient.
