Anti-blocking drainage tube

Abstract

The invention provides an anti-blocking drainage tube which comprises a main part comprising a first end and a second end. The first end is provided with a guide-in port tube, and a plurality of spindle-shaped drainage holes are formed around the first end of the main part. The problem of blockage of the drainage tube when liquid and solid ingredients are drained and conveyed to other places underaction of negative pressure attraction can be solved effectively. The drainage tube can be used for phlegm suction under action of negative pressure attraction, gastral cavity pressurizing drainage flushing, vomica pus way drainage flushing, drainage and flushing of various osteomyelitis and arthritis and drainage and flushing of various surgical incisions and has anti-blocking effect.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anti-clogging drainage tube. Background technique [0002] In the process of diagnosis, treatment and research of human and animal bodies, some redundant, harmful and pathological liquid solid components often appear, and these components often further cause damage and pathological changes to surrounding tissues. The extraction of these components is often the most important means for diagnosis and treatment of such lesions. However, it is often difficult to extract these components. Because the pipeline or space that is conveyed by drainage is often very small, limited, or even there is no ready-made pipeline or space. Drainage, aspiration and collection of viscous sputum, secretions, necrosis and inflammatory substances in the lungs, trachea and bronchi; case examination and culture; gastric cavity decompression and drainage in cases of food poisoning, gastric cont...

AI Technical Summary

Problems solved by technology

[0003] The invention provides an anti-clogging drainage tube, which can effectively solve the problem of drainage tube blockage when liquid and solid components are drained and transported to other places under the action of negative pressure suction. Sputum, gastric cavity decompression drainage and irrigation, abscess cavity and pus channel drainage and irrigation, drainage and irrigation of various osteomyelitis and arthritis, drainage and irrigation of various surgical incisions, etc., all have anti-clogging effects
