Description

Novel medical suction tube assembly

Technical Field

The utility model relates to the technical field of suction tubes, in particular to a novel medical suction tube assembly.

Background

The suction tube belongs to medical auxiliary instruments, has a plurality of types, and is mainly used for orthopedics, brain surgery, obstetrics and gynecology, urology, thoracic surgery and the like. The thoracoabdominal suction tube is mainly used for thoracic surgery and general surgery to play a role in sucking fluid in clinical operations.

The existing disposable suction tube has large inner diameter, but the inner diameter of the interface of the two ends of the disposable suction tube is smaller, which easily causes the blockage of the outlet of the suction tube. The reasons for the blockage of the suction tube outlet are generally two: firstly, after the suction tube sucks various residues, the residues cannot be sucked out after the direction and the angle of the residues are changed in a pipeline, so that obstruction is caused; and secondly, the outlet connecting end is conical, gaps exist around the outlet connecting end, and after the residue is sucked by the suction tube, fine residue is filled in the gaps around the outlet connecting end, so that the outlet becomes narrower, and secondary obstruction is caused. Obstruction can also be caused by narrow outlet due to incarceration of residues and foreign matters.

In the operation process, the suction tube is often blocked and needs to be replaced for 2-3 times, so that a large amount of operation time is delayed, and meanwhile, the wound surface and the abdominal cavity are easily infected due to untimely suction, and infection or abscess is formed in the later period. In the orthopedic surgery, because bone fragments are infarcted and the suction is not timely, fat embolism can be caused to endanger life. The bleeding point can not be found and treated quickly in the operation, which causes the increase of the bleeding amount.
