Description

Cross large channel drainage pipe joint device

Technical Field

The utility model belongs to the field of drainage tube connectors for medical surgery and medical treatment, and relates to a cross large-channel connector device.

Background

The cross large channel drainage tube is integrally formed by three sections of different structures, has excellent anti-kink property, is internally broken with four fully-open drainage grooves, can drain any point in the body, has the advantages of good drainage effect, difficult blockage and reduced postoperative infection possibility, and is a medical technology widely applied to guiding pus, blood or other liquid accumulated in human tissues or cavities to the outside. When a patient carries out drainage treatment, one end of the drainage tube is inserted into a human tissue or a cavity, and the other end of the drainage tube is connected with a drainage bag to collect drainage liquid which flows out. For a patient needing long-time drainage, a drainage bag is required to be replaced in drainage, and when the drainage bag is clinically replaced, medical staff can bend the drainage tube so that the drainage tube is bent and sealed, and drainage liquid in the drainage tube does not flow out any more when the drainage bag is replaced. Moreover, such an operation mode usually needs two medical staff to cooperate to perform the operation, which is very inconvenient. In particular, such bending and sealing is firstly unreliable, and the problem of drainage liquid outflow often occurs, and bending the drainage tube can squeeze the drainage liquid in the drainage tube to a certain extent, so that when the connection between the drainage tube and the drainage bag is pulled out, the drainage liquid can splash, and virus pollution is caused.

At present, a flow stopping clamp is installed on a drainage tube, when a drainage bag needs to be replaced, the flow stopping clamp is closed to clamp the drainage tube, and then the connection between the drainage tube and the drainage bag is disconnected, although the sealing reliability of the drainage tube can be greatly improved in such a way, drainage liquid still exists in the drainage tube below the flow stopping clamp after the flow stopping clamp is closed, after the connection between the drainage tube and the drainage bag is pulled out, the drainage liquid at the port position of the drainage tube can possibly shake due to the drainage tube, and under the action of gravity, the drainage liquid drops, so that the risk of pollution of external environment is also caused; when the drainage tube and the drainage bag are reconnected, the drainage liquid still has the problem of outflow pollution of the drainage liquid because the drainage tube below the clamp is internally provided with the drainage liquid.
