Abstract

1,130,593. Surgical syringes. NOVO TERA PEUTISK LABORATORIUM A.S. 27 April, 1966 [30 April, 1965], No. 18432/66. Heading A5R. A syringe in which a solid 15 and a solvent may be mixed immediately before an injection, comprises an outer cylinder 10 for the solid, within which a foremost plunger 11 defining a chamber 14 for the solvent is slidable, the foremost plunger being locked initially to the cylinder by pawls 32 which are released when a rearmost plunger 12 is projected a predetermined distance in the foremost plunger 11 and ducts 24 in the foremost plunger which open to communicate the foremost plunger chamber 14 with the cylinder chamber 13 before the pawls are released. The ducts 24 are normally closed by an apertured elastic cap 25, the aperture 28 normally receiving a stud 29 fixed to the plunger. On creation of an overpressure in the foremost plunger chamber 14 by projecting the rearmost plunger, the centre of cap 25 is forced away from the stud, thus opening the ducts for passage of solvent into the cylinder chamber 13. A cylindrical skirt 37 secured to the rearmost plunger then disengages the pawls 32 from a shoulder 38 in the cylinder, thus releasing the foremost plunger 11. After the solvent and solid have been mixed, and replacement of a cap 22 at the forward end of the syringe by a cannula 43, which causes a needle 21 to pierce a diaphragm 20, the injection is made by projection of both plungers together. The skirt 37 fits between the foremost plunger and the cylinder to seal the interior of the cylinder at the rear.
