Connecting piece and anti-blocking drainage device

Abstract

The invention discloses an anti-blocking drainage device. The device comprises a suction part, a connecting piece and a collecting container. One end of the connecting piece is connected with the suction part; the other end of the connecting piece is connected with the collecting container; the other port of the collecting container is connected with a negative pressure center; the connecting piece comprises a first connecting part, a second connecting part and a transition part; the first connecting part is connected with the transition part, and the transition part is connected with the second connecting part; and port sections of the two ends of the transition part are smaller than port sections of the first and second connecting parts respectively, and bosses are formed at joints of ports of the two ends of the transition part and ports of the first and second connecting parts. According to the device, the suction part and the collecting container form a channel with a smooth pipeline inner wall through the connecting piece, soft tissue or crushed bone scraps in the operation process can be smoothly conveyed to the collecting container, smooth completion of operations is ensured, the caliber of the connecting piece is matched with the caliber of the suction part and the caliber of a container port of the collecting container, and the phenomenon of accumulation and blockage in a pipeline is prevented.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anti-blockage drainage device for a connecting piece. Background technique [0002] In surgical operations, it is usually necessary to use methods such as excision, cleaning, flushing and scraping. The soft tissue and bone debris generated during the operation should be removed in time. Generally, various drainage devices or drainage devices are used. Drainage devices are used after body cavity surgery. Medical supplies used for drainage and collection of body fluids outside the body; the drainage device in the prior art is aimed at the working surface in the body cavity that needs to be cleaned through the drainage tube, and the free soft tissue or bone debris is transported to the drainage bag or drainage bottle behind through the drainage tube However, due to the relatively thin drainage tube and the inappropriate connection between the drainage tube and the drainag...

[0002] In surgical operations, it is usually necessary to use methods such as excision, cleaning, flushing and scraping. The soft tissue and bone debris generated during the operation should be removed in time. Generally, various drainage devices or drainage devices are used. Drainage devices are used after body cavity surgery. Medical supplies used for drainage and collection of body fluids outside the body; the drainage device in the prior art is aimed at the working surface in the body cavity that needs to be cleaned through the drainage tube, and the free soft tissue or bone debris is transported to the drainage bag or drainage bottle behind through the drainage tube However, due to the relatively thin drainage tube and the inappropriate connection between the drainage tube and the drainage bottle interface, soft tissue or bone fragments will accumulate in the narrow part of the tube, which will cause blockage and hinder the smooth progress of the operation, sometimes even The operation will be interrupted, and the blockage in the pipeline must be cleaned up before the operation can be performed again
