Abstract

457,152. Hypodermic syringes. COOK LABORATORIES, Inc., 170, Varick Street, New York, U.S.A.-(Assignees of Montuori, F. C. ; Medical Science Building, Washington, U.S.A.) Jan. 21, 1936, No. 1947. Convention date, Nov. 14, 1935. [Class 81 (ii)] A hypodermic syringe comprises a tubular body having a longitudinal aperture for the insertion of a cartridge, a retaining member adapted to engage with and hold the cartridge in position and resilient means, anchored within the body, which engage with the cartridge when this is inserted into the body and constantly urge it outwards thereby automatically ejecting the cartridge when the retaining means is rendered inoperative. As shown, the hollow barrel 1 of the syringe is provided with a longitudinal aperture 11 through which a cartridge 2 is inserted. The cartridge retaining member consists of a slidable hollow collar 8 which is held in its operative position by a 'coiled spring 9. An outward movement of the plunger rod 7 compresss the spring 9 and frees the cartridge from the locking action of the collar 8 whereupon a leaf spring 16 forces the cartridge 2 out of the barrel. At the same time a leaf spring 15, the end of which lies in a guideway 17 provided in the collar 8 (See Fig. 4), operates to arrest the action of the spring 9 on the collar 8 by resting against a bridge 20. The insertion of a cartridge compresses the left springs and the locking action of the collar 8 comes into operation through the expansion of the spring 9. An inward movement of the plunger-rod 7 then pushes a slidable plug 14 in the cartridge thus ejecting medicament through a needle 4. The barrel of the syringe is provided with an indentation in alignment with the spring 15 which brings the guideway 17 into alignment with the spring. U.S.A. Specification 1,757,809 is referred to.
