Timed cut-off system applied to drainage tube

Abstract

A timed cut-off system applied to a drainage tube comprises a positioning mechanism used to position the drainage tube, a cut-off mechanism and a control unit, wherein the cut-off mechanism comprises a slide rail and a main shaft, a round extrusion plate is disposed on the end part of the main shaft, and an arc raised part is disposed on the round extrusion plate; and the positioning mechanism comprises an extending plate and a supporting plate I, an arc raised thin block is disposed on the supporting plate I, a neck I is formed in the arc raised thin block, a fixed stop dog is disposed on the neck I, the other side of the neck I is equipped with a movable clamping block made of an elastic material, the movable clamping block comprises a plate-shaped part and two clamping parts, and slideways clamped on edges of the arc raised thin blocks are formed in the middle parts of the two clamping parts. According to the invention, the drainage tube can be opened and closed at scheduled time; and the system is applicable to drainage tubes with different sizes, so workloads of medical workers are relieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a timing cut-off system for a drainage tube. Background technique [0002] After surgery, in order to remove the fluid (including blood, pus, inflammatory exudate, bile, secretion, etc.) accumulated in the body cavity, joint, organ or tissue from the original place and excreted, it is often necessary to place a drainage tube , to prevent accumulation in the body cavity, secondary compression symptoms, infection or tissue damage, and the observation of the drainage situation through the drainage tube can also detect the changes of the disease early. After the blood, exudate and tissue secretion are drained, the local pressure can be reduced , Reduce the damage of liquid to surrounding tissues, reduce the possibility of co-infection, and facilitate wound healing. [0003] There are many types of surgical drainage tubes used clinically, some are used for catheterization, so...
