Abstract

271,645. Groves, W. W., (Cook Laboratories, Inc.). May 25, 1926. Syringes.-A hypcdermic syringe 1 has an end cap 11, hinged thereto about an axis normal to the section shown and held in position during use by a spring-pressed locking sleeve 16 through which the plunger 4 passes. The lock is released to open the syringe by pulling out the plunger 4 the head 18 of which engages the locking sleeve. The end of the syringe barrel 1 is cut obliquely providing a cam surface which presses back the sleeve 16 automatically during the closing of the syringe and provides clearance for the cap 11. The syringe barrel 1 is adapted to receive a medicament-containing ampoule 5, closed at one end by a flanged hollow plug 6 which can be pierced by a cannula 3 formed integrally with the hypodermic needle. 2, and at the other by a plug 7 engaged and pressed inwards bv the head 18 of the plunger 4. The sleeve 16 engages and presses upon the end of the ampoule 5 when the syringe is closed.
