Abstract

1451826 Syringes JINTAN TERUMO CO Ltd 27 March 1974 [29 March 1973] 13610/74 Heading F1R A micro-syringe having a cannula 3 inserted in the bore 2 at one end of the syringe has a flexible hollow guide 7 secured to the other end and through which an elongate plunger 8 may be fed into the bore 2, the flexibility of the guide preventing permanent buckling of the plunger. The guide is removably inserted into the flange 5 or may be fixed thereto. Several shapes of guides are described.
