Abstract

The drip chamber 12 has a floating pressure-sensitive ball 68, which responds to priming pressure and the pressure of liquid in the administration set, and a resilient seat 62 shaped so as to provide line contact with the ball. An inwardly- turned lip 66 on the seat inwardly flexes as the ball pushes into the valve seat to maintain the line contact. <IMAGE> [GB2028975A]
