An infusion apparatus.

摘要

A disposable infusion set includes a pressure responsive chamber (1) for location in a key-hole shaped slot (44) in a pressure monitor. The pressure responsive chamber (1) comprises a substantially rigid, hollow housing (10) having a flanged end face (11), and a resilient flexible diaphragm (12) connected to the flange (11) and covering the end face. The housing also includes a liquid inlet (16) and a liquid outlet (17) passage in communication with the inside of the housing (10). The liquid inlet (16) and outlet (17) passage are mutually orthogonal with one of them extending normally away from the diaphragm. Finger gripping means (18,19,20) extending between the liquid inlet (16) and outlet (17) enable the pressure responsive chamber (1) easily to be manoeuvred into the key-hole shaped slot (44).
