Drainage device capable of regulating drainage area

Abstract

The present invention discloses a drainage device capable of adjusting a drainage area. The drainage device comprises an outer sleeve pipe and also comprises an inner sleeve pipe structure, a connection structure and a suction adjustment structure; a plurality of drainage holes are arranged in an outer circumference of the outer sleeve pipe, the inner sleeve pipe structure comprises an inner pipeand a bifurcation structure; the suction adjustment structure is connected with a top end of the connection structure; the suction adjustment structure comprises a bracket, a bottom end of the bracketis fixedly connected with the top end of the connection structure, the bracket is provided with a space for passing out of bifurcation ends and an adjustment member, and the adjustment member is fixedly arranged on the bracket and contacts with the bifurcation structure to press the bifurcation ends. By arranging the inner sleeve pipe structure, the drainage device in human body can also conductdrainage of liquid near bifurcation suction holes in the bifurcation ends by the bifurcation structure in the inner sleeve pipe structure; and users only need to push the inner pipe, so that the adjustment member of the suction adjustment structure contacts and presses the bifurcation ends to conduct drainage of different areas in body cavities.

Description

Technical field [0001] The invention relates to the technical field of medical drainage equipment, in particular to a drainage device with an adjustable drainage area. Background technique [0002] In medical clinics, in order to prevent postoperative infections and promote postoperative wound healing, it is often necessary to apply a drainage tube device to a patient after surgery. It can remove pus, blood and fluid in the body tissue or body cavity. And so on to the body. Drainage tube devices are used in multiple post-operations, including chest cavity, brain cavity, gastrointestinal tract, biliary tract, etc. [0003] Most of the drainage tubes in the prior art are cylindrical and tubular structures with drainage holes on the outer circumference, which are inserted into the patient's body during use, and negative pressure is connected to the drainage tube, so that the pus, blood and liquid in the body cavity are drained The hole is led out of the body. [0004] However, in the...

AI Technical Summary

Problems solved by technology

[0005] 1) The drainage tube in the prior art is cylindrical, and its adsorption range is limited after entering the body cavity of the human body, resulting in poor drainage effect;

[0006] 2) The drainage tube in the prior art can only drain pus, blood and liquid near the body cavity of the human body, and negative pressure drainage of the same area for a long time will cause damage to the organs there
