AI Technical Summary
Technical Problem
After the existing hepatic ascites aspirator is suctioned, the residual liquid in the pipe may flow back into the patient's body, endangering the patient's safety.
Method used
A hepatic ascites aspirator for infectious liver disease was designed, and the anti-reflow component was used to set up in the inlet tube. When the liquid was extracted, the anti-reflow component was used to seal the inlet tube to prevent the liquid from flowing back.
Benefits of technology
It effectively prevents the fluid from returning to the patient's body from the ascites aspirator, improving the patient's safety.

Abstract
This utility model relates to the field of medical device technology, specifically a suction device for ascites in infectious disease patients. It includes a collection tank with an air extraction tube connected to an external air extraction device. An inlet tube is also provided on the collection tank, with a needle at the end of the inlet tube furthest from the collection tank. An anti-backflow component is also included, located inside the inlet tube. When the collection tank is full and needs replacement, the air extraction device stops operating. The liquid in the inlet tube may backflow due to the pressure difference between the inside and outside of the body. At this point, the inlet tube can be pulled out slightly. This movement of the inlet tube causes the fixing plate and top cover to move. The top cover, losing the force of the top block, re-fits the fixing plate, sealing the inlet tube and preventing liquid backflow into the patient's body.
