Description

Adjustable negative pressure drainage device

Technical Field

The utility model belongs to the technical field of the negative pressure drainage, especially, relate to a negative pressure drainage device with adjustable.

Background

Present negative pressure drainage tube includes thick rubber tube, and the tail end connection negative pressure suction device of thick rubber tube is through inside and outside atmospheric pressure difference, carries out the drainage to liquid, and the opening is blockked up by the muscle after the drainage needle pierces the skin easily, and the gap of drainage department is less simultaneously can reduce drainage speed, leads to can not normally drainage.

SUMMERY OF THE UTILITY MODEL

To the technical problem, the utility model provides a negative pressure drainage device with adjustable supports the inner wall of muscle through the drainage groove, makes liquid flow from the recess inboard to through the aspirator from the pressure regulation function in area, the adjustment pressure size.

The technical scheme is as follows: an adjustable negative pressure drainage device is characterized in that the front end of a portable aspirator is provided with a pressure regulating knob, and the left upper part of the portable aspirator is in threaded connection with a spiral storage tank; one end of the air suction pipe is communicated with the air inlet end of the portable aspirator, and the other end of the air suction pipe is communicated with the right upper part of the inner side of the spiral storage tank; the lower part of the outer side of the punctured drainage tube is respectively provided with an annular groove and a drainage groove, and the inner side of the punctured drainage tube is respectively provided with a main drainage hole and an auxiliary drainage hole.

Preferably, the upper part of the penetrating drainage tube is glued with the upper left part of the connecting hose, and the inner side of the penetrating drainage tube is communicated with the inner side of the connecting hose.

Preferably, one end of the air suction pipe is glued with the spiral storage tank, and the other end of the air suction pipe is in threaded connection with the portable aspirator.

Preferably, the portable aspirator is a aspirator with the model of JXD, and a pressure gauge, a switch and an indicator lamp are respectively installed at the front end of the portable aspirator.

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

the utility model discloses in, annular groove, main drainage hole, drainage recess and the setting in supplementary drainage hole, be favorable to supporting the inner wall of muscle, be that liquid flows from the gap of inboard, normally introduce through main drainage hole and supplementary drainage hole at last.

The utility model discloses in, the setting of portable aspirator and pressure regulating knob, be favorable to the pressure regulation function through portable aspirator self, the adjustment pierces the inboard negative pressure of drainage tube, prevent that too big muscle that leads to of pressure from hugging closely in the inboard of supplementary drainage hole.
