Abstract

1385531 Drainage appliances PETER STEER DEVELOPMENTS Ltd 5 July 1973 [29 Aug 1972] 39936/72 Heading A5R A surgical drainage device comprises a valve chamber 1 having a liquid inlet 2 and a liquid outlet 4 arranged opposite each other, a main valve 6 inside the chamber 1 in line with inlet 2 and outlet 4, so that a trocar can be passed therethrough, the main valve 6 being opened by passage of the trocar but being unable to open under pressure of liquid, and a non-return valve 7 communicating with the inlet 2 to by-pass the main valve 6 and to permit liquid flow from the inlet 2 into the chamber 1 but not in the reverse direction. Chamber 1 is made of transparent, preferably flexible plastics material, of cylindrical, elliptical or oval cross-section. A catheter 3 is preferably permanently attached to inlet 2. A trocar is inserted through outlet 4, valve 6, inlet 2 and catheter 3. When the trocar is withdrawn, valve 6 closes under spring action. Liquid flows through catheter 3, inlet 2 and a non-return valve 7 into chamber 1 and out by outlet 4. Thus, in case of mishap air entering chamber 1 from outlet 4 cannot enter the patient's body via catheter 3.
