Novel structure multifunctional drainage device

Abstract

The invention discloses a novel structure multifunctional drainage device which comprises a drainage bag and a drainage channel. A liquid inlet of the drainage channel is communicated with a chest ofa patient, a liquid outlet of the drainage channel is communicated with a liquid inlet of the drainage bag, the drainage channel comprises a thin drainage pipe and a thick drainage pipe, the outer diameter of the thin drainage pipe is smaller than 2.0mm, the outer diameter of the thick drainage pipe is larger than 10mm, the thick drainage pipe includes a first thick drainage pipe and a second thick drainage pipe, the first thick drainage pipe is communicated with the second thick drainage pipe through a tee valve, and a liquid outlet of the first thick drainage pipe is communicated with a liquid inlet of the drainage bag. According to the device, counter flow of liquid flowing in the drainage bag is avoided, the contact area between the liquid and the chest of the patient is reduced, the discomfort of the patient is relieved, pain of the patient is relieved, contact between the liquid outlet pipe and the ground is avoided, a pollution source cannot enter the drainage bag from the liquid outlet pipe, safety of the drainage device is improved, and air cock formed in the drainage pipe can be effectively avoided, so that continuous and smooth drainage of the drainage pipe can be achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multifunctional drainage device with a new structure. Background technique [0002] After the operation, there is effusion in the patient's body or deep in the surgical site, which needs to be drained with a tube to prevent infection. After intubation, the connector of the drainage bag is connected to the intubation tube, and the effusion is drained into the transparent bag. After a certain amount of liquid, open the liquid outlet valve to discharge the liquid from the liquid outlet pipe. [0003] The prior art drainage bags for pleural effusion have the following disadvantages: 1. In the process of use, the patient accidentally or foreign matter presses the drainage bag, which can easily lead to backflow of the liquid in the drainage bag, causing infection and even affecting the patient's health. Recovery; 2. The outer diameter of the entire drainage tube is the same,...

Problems solved by technology

[0005] In order to solve the problems existing in the prior art, the object of the present invention is to provide a device with reasonable design and simple structure, which can avoid the backflow of the liquid flowing into the drainage bag, reduce the contact area with the chest cavity of the patient, and reduce the discomfort of the patient. Reduce the pain of the patient, avoid the contact between the liquid outlet pipe and the ground, effectively prevent the pollution source from entering the drainage bag from the liquid outlet pipe, improve the safety performance of the drainage device, and effectively avoid the occurrence of air embolism in the drainage pipe. A multi-functional drainage device with a new structure that can make the drainage tube drain continuously and smoothly
