Abstract

1431846 Syringes COMPASELECT GmbH 25 July 1973 [3 Aug 1972] 35408/73 Heading F1R [Also in Divisions AS and A6] A syringe has a contents scale and a comparison mark, either or both of which is displaceable relative to both the cylinder and piston to thereby obtain zero setting irrespective of the longitudinal position of the piston in the cylinder. A scale carrier 4 is frictionally held on a transparent cylinder 1 of a phial for use in a syringe frame. Zero of the scale 5 may be brought over the edge of piston 3 in any longitudinal position. An alternative construction provides graduated piston-rod 9, Fig. 3a, and a ring 11 carrying a mark 10. The ring is loaded by spring 13 into contact with shoulder 12 on the rod, when the mark is aligned with the scale zero. While the scale moves during an injection the ring is held relative to the cylinder by engagement between segmental abutments 16, 16a, formed similar to a screw thread on the ring and handle 8 respectively. Handle 8 is mounted on a phial so that the piston-rod engages the piston stopper of a phial. Engagement and disengagement between the abutments is effected by partial rotation of the handle, the ring being disengaged to be moved to the shoulder by spring 13 to reset to zero. In another construction abutments 16a are carried in a tube (14) Fig. 4a (not shown) fixed against rotation to the end of a phial. A handle (8) rotatably mounted on the phial and tube (14) and linked to the piston-rod by lugs and grooves (23, 17). In a modification the segmental abutments are replaced by a detent (19) Fig. 5 (not shown) releasably engaging serrations along the length of ring 11. An adjustable stop nut (22) Fig. 6 (not shown) on a threaded piston-rod provides a positive limitation of injection quantity. The preparation of solutions may be facilitated by provision of appropriate syringe scales, the syringe contents being injected into containers of solute of standard volumes.
