Abstract
The invention provides a syringe for detecting pressure change. The syringe includes a barrel defining a reservoir for receiving a constituent, a piston movable within the reservoir and a plunger. The barrel further includes a proximal end and a distal end with an outlet, an engaging member with a pair of fingers formed on an outer periphery of the barrel and a rib extending from the outer periphery of the barrel and disposed proximally to the engaging member. The plunger includes a first plunger part, a second plunger part and a baseplate supporting the first and second plunger parts. The first plunger part is partially received by the reservoir and slidably engaged with the piston. The second plunger part further includes at least one stop ledge to which the fingers of the engaging member releasably latch, and the stop ledge formed on a periphery of the second plunger part, and a compartment for accommodating a first biasing member with first and second ends. The first and second ends of the first biasing member engage with the rib and the baseplate respectively.
