We have had a stainless steel well constructed * for use in extracorporeal circulation systems. This apparatus facilitates: (1) measurement of perfusion pressure; (2) addition of materials to the system; (3) withdrawal of samples for analysis; (4) monitoring of the temperature of the perfused blood; (5) removal of trapped air by external venting.

Description  The chamber is constructed of highly polished stainless steel (Figs. 1 and 2). It is 4.7 cm. in depth and has an inner diameter of 2.1 cm. and a capacity of 16 cu. cm. The cap is screwed into the main chamber over a rubber gasket. Into the top of the cap is welded a ridged stainless steel nipple which is adapted to plastic tubing (Mayon) of 1/4 in. internal diameter. In the perfusion system, this nipple is connected by a 25 cm. length of tubing, loosely plugged above with sterile cotton to a Tycos manometer. Air
