Abstract

The present article is a two-way medical check valve used, for example, in a fluid delivery line for delivering a medicinal liquid to the human body. The medical check valve has two duckbill valves with their tips butted together to prevent backflow or overdosing when negative pressure is generated upstream or downstream of the fluid delivery line.
