Abstract

1448129 Syringes SGE RESEARCH PTY Ltd 10 Dec 1973 [18 Dec 1972] 57122/73 Heading F1R [ Also in Division A5] A syringe has a telescopic needle guide 18 with inner section 27 having a bore slidable over needle 7 and a flange 25 to extend the sleeve, the sections being maintained in telescopic relationship, when extended, by shoulder pairs 28, 23 and 29, 30. Outer section 21 is welded at 22 to a nut 10 screwed on to a boss 8 of barrel 6 to hold needle 7 in bore 12, while a seal is maintained by compression spring 14 pushing a needle stop 13 against a washer 16. Button 17 moves plunger 9 in a larger cross-section bore 11. Sections 26, 27 retract when flange 25 contacts the skin or membrane (31) and needle 7 passes through. In modifications, only two guide sections are provided. with a helical spring for automatically extending the sleeve extending coaxially and outside of the sleeve between nut 10 and flange 25 or between nut 10 and shoulder 29 inside the sleeve. The guide may be secured separately from the needle to apparatus into which a syringe needle is to be inserted.
