Abstract

1,185,659. Hypodermic syringes. R. B. BLACK. 28 April, 1967 [28 April, 1966], No. 19686/67. Heading A5R. A hypodermic syringe comprises a tubular body 102, 103 for receiving a piston and cylinder type of cartridge 105, 106 containing material to be injected, a mount 108 for a hypodermic needle which will penetrate the cartridge, and means on the tubular body for advancing the cartridge in the body while restraining the piston so that aspiration may be effected through the needle, there also being means in the body for advancing the piston into the cylinder to expel the material in the cartridge. As shown, the syringe contains in a capsule 114 gas under pressure which, when a brake device 116 is released, acts on a piston 111 so as to move this piston together with the piston 106 of the cartridge to eject the injection material. In use, the hypodermic needle is inserted into the patient and an operating lever 121 is depressed (to the position of Figure 2, not shown) so that a finger 124 on the lever moves through a slide 125 the cylinder of the cartridge. Aspiration is thus effected since the piston 106 of the cartridge is secured by a harpoon device 113 to the piston 111 which is held stationery by the spring loaded brake device 116. To eject the contents, the operating lever is depressed further (to the position of Figure 3, not shown) and acts on a member 120 so as to release the brake device 116, the gas in the capsule then causing the pistons 111, 106 to move to the left and eject the cartridge contents. After use, the gas may be re-charged into the capsule either by returning the piston 111 to its original position, or by inserting a charging needle through a plug 115 in the capsule.
