A drainage device for use in the care of a gastrointestinal tumor

PendingCN122272933AOncologic NursingGastrointestinal tumor
This invention belongs to the field of medical drainage technology, specifically a drainage device for the care of gastrointestinal tumors. It includes a valve assembly, a valve adjustment assembly, an automatic cleaning assembly, a frame assembly, a liquid storage assembly, and a gas filtration assembly. The valve assembly is mounted on the frame assembly, and the valve adjustment assembly and the automatic cleaning assembly are located within the valve assembly. This invention cleverly utilizes changes in negative pressure within the valve body to trigger a cleaning action. When deposits on the inner wall obstruct the airflow, the reduced air pressure automatically overcomes the spring force, causing the piston to slide. This, in conjunction with a scraper ring, mechanically scrapes away the blockage from the inner wall of the valve body and pushes the obstruction into an independent storage bottle. This process achieves in-situ unblocking without disassembling the tubing, effectively preventing drainage interruption and significantly reducing the probability of cross-infection.
