In the initial state as shown in fig. 6, the sealing plate 18 is contracted inside the bottle stopper 2 so as not to affect the movement of the bottle stopper 2; after inserting bottle plug 2 inside drainage bottle 1, rotatory change 19, change 19 drives the closing plate 18 through cylinder 20 and rotates for the closing plate 18 withstands the inner wall of drainage bottle 1, as shown in fig. 2 and 5, the closing plate 18 is connected with the inner wall friction of drainage bottle 1, can strengthen the stability of bottle plug 2, can strengthen the leakproofness between bottle plug 2 and the drainage bottle 1 simultaneously.

The sealing plate 18 can form a circle corresponding to the inner wall of the drainage bottle 1 after being extended in a rotating mode, and the rubber pad is arranged, so that the installation stability and the sealing performance of the bottle stopper 2 can be further improved.

According to specific patient's health condition, accessible vacuum pump 101 carries out the negative pressure increase to drainage bottle 1, is applicable to different patient's treatments.

The front, the back, the left, the right, the upper and the lower are all based on figure 1 in the attached drawings of the specification, according to the standard of the observation angle of a person, the side of the device facing an observer is defined as the front, the left side of the observer is defined as the left, and the like.
