ABSTRACT:
A casing (20) includes a casing body (30) defined by a pair of lateral wall portions (32a, 32b) which are symmetric about a longitudinal plane (P) to define an ovoid transverse cross-section. The casing includes a lower fitting (35) that is connected with a source (23) of motive liquid (22) under pressure. A deformable enclosure (38) is sealed to an upper edge flange (41) of the casing. The deformable enclosure is drawn open (FIG. 9b) against a grid or cage (44) to receive a flexible pouch (18) that contains a medical liquid (19). A length of flexible tubing (17) connected to the pouch extends through a passage (37) in a cover or stopper (46) which is received on the casing body with a fluid tight seal. Under further motive fluid pressure, the flexible pouch (18) is squeezed, forcing the medical liquid through the tubing (17, 15, 9) to a cannula or other injection device (3).
