Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a medical negative pressure suction tube connection device. Background technique

[0002] The negative pressure suction tube is a connecting tube used to connect the negative pressure device and the extraction part. Most of them are rubber tubes. In this case, the joint is subjected to a large force from the outside, which will cause the joint to separate, and the use stability is low, and during use, the transmission material leaks at the joint, and the practicability is low. Contents of the invention
