AI Technical Summary

Technical Problem

Existing drainage tubes have limited coverage in multi-regional anastomotic surgeries, lack double-tube flushing and anti-blocking functions, and cannot achieve the correspondence between intra-abdominal multi-regional drainage and extra-abdominal zonal management, making it difficult to accurately intervene in anastomotic leakage and increasing the risk of infection.

Method used

A multi-channel, independent zoned active drainage tube is designed, which adopts a four-branch structure. It has independent channels inside and outside the abdominal cavity and a double-tube structure for dripping. Combined with a negative pressure drainage component and a diversion controller, it can realize zoned monitoring and control and has a flushing and anti-clogging function.

Benefits of technology

It enables precise drainage management of multi-regional anastomoses, reduces the reoperation rate, reduces the number of punctures, prevents blockage, ensures non-invasive tube removal, and reduces the risk of infection.

Abstract

The application discloses a kind of multi-channel independent partition active drainage tube, belong to medical instrument technical field.Drainage tube includes catheter main body, intra-abdominal bifurcated portion, abdominal cavity outside bifurcated portion, drop flushing component, negative pressure drainage component and shunt controller.Intra-abdominal bifurcated portion includes four branch pipes of coaxial double-cannula structure;Four independent longitudinal channels are arranged in catheter main body, four intra-abdominal branch pipes and four extracorporeal branch pipes are communicated one by one and isolated from each other respectively.The application realizes "one pipe four areas" and accurate partition control, and medical staff can intuitively monitor the state of each partition through the pressure indicator of shunt controller, and manually intervene when necessary by operating independent regulating valve and drop flushing component, to realize active flushing suction and online backwashing to prevent blockage.The application can effectively prevent and treat multiple anastomotic fistula after complex operation, avoid the risk of pressure or pipe blockage between different areas, and reduce the rate of secondary operation.
