Title:
医用注射器に関する改良
Document Type and Number:
Japanese Patent JP4070408
Kind Code:
B2
Abstract:
A syringe (1) contains a liquid medical substance which has to be mixed with another substance before use. This is done by interconnecting the syringe (1) and a capsule containing the other substance by a transfer device (2) which screws into a socket (4) in the piston-seal (3) of the syringe (1) and penetrates through into the liquid. The device (2) extends slidably but non-rotatably through a screw cap (8) which fits to the rear end of a housing (13) for the syringe (1). As the cap (8) screws on, so does the transfer device (2) screw into the piston-seal (3). The relationship between the screw threads is such that, on removing the screw cap (8), the transfer device (2) disengages from the piston-seal (3) first, so that the latter cannot be inadvertently removed from the syringe.
