Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1, accurate negative pressure drainage device of disposable, including drainage bag 6, its characterized in that, the fixed intercommunication in drainage bag 6 upper end has drain pipe 5, the fixed intercommunication in drain pipe 5 upper end has gasbag 2, the fixed intercommunication in gasbag 2 upper end has liquid inlet head 1, the fixed intercommunication in drainage bag 6 lower extreme has clear liquid pipe 9.

In this embodiment, 6 front ends of drainage bags are fixed along vertical direction and are provided with scale registration 7, through above-mentioned design, can improve the precision of drainage. Be provided with first ooff valve 8 on the clear liquid pipe 9, be provided with second ooff valve 10 on the drain pipe 5, be provided with third ooff valve 11 on the liquid inlet head 1, through above-mentioned design, can be convenient for control the circulation of clear liquid pipe 9, drain pipe 5 and liquid inlet head 1. 2 bottom left ends of gasbag are fixed the intercommunication and are had breather pipe 4, the screw thread is provided with pipe cap 3 on breather pipe 4, through above-mentioned design, can be convenient for clear up the drainage liquid that remains in gasbag 2.
