Abstract (en)
[origin: WO9302727A1] A syringe device (10) which is not reusable after the first delivery stroke. The syringe has a hollow body (11) slidably containing a plunger (12) in fluid sealing relationship. The plunger (12) has a plunger rod (13) which includes a guide arrangement (17) receiving and guiding a locking member (18). The guide arrangement (17) is adapted to maintain the locking member (18) in an unengaged position relative to the body (11) when the plunger (12) is moved in the direction of a first intake stroke and in a first delivery stroke, and allows relative sliding movement and consequential pivoting movement of the locking member (18) such that, upon commencement of a second intake stroke, the locking member (18) snaggingly engages the inside surface of the body (11) to resist further movement of the plunger (12) in the intake stroke direction. Accordingly, in use, the locking member (18) interacts with the guide arrangement (17) of the plunger (12) and the inside surface of the body (11) so as to allow a first intake stroke and a delivery stroke, but to prevent a second intake stroke of the plunger (12). The syringe device (10) may also allow for aspiration testing, and may have a plunger rod (113) which has two interacting parts (113A, 113B).
