Abstract

1513463 Syringes W WAGNER 9 May 1975 15550/75 Addition to 1494646 Heading A5R A syringe comprises a muzzle 1 for placement against the skin and within which a vacuum is generated, for example by spring- loaded piston 12 which is held is displaced position shown by detent means including a latching member 2 on piston rod 24 engaging the edge of an aperture in a stem 13 carrying a plunger 49 which is depressed on contact with the skin to release latching member 2 whereby piston 12 moves back to effect a vacuum in muzzle 1 thereby drawing skin into the muzzle. The vacuum also acts through bore 6 on a piston 112 which is drawn downwardly in its housing 109 thereby releasing a catch 110 to permit a cross head 114 to move downwardly, an anvil 5 on the cross head striking the syringe to effect injection. Cross head 114 strikes piston 112 and moves it into contact with a valve member 119 which moves downwardly permitting air to flow through port 108 upwards alongside member 119 past the upper edge thereof into bore 6 and thence to muzzle 1 to break the vacuum therein.
