JET INJECTION UNIT WITH RESILIENT LIQUID CHAMBER

摘要

A jet injection device comprising a base member (160), a load member (130), a resilient liquid chamber (143) being in fluid connection with an outlet orifice (142) in one end and an inlet channel (156) in the other end, an impulse transferring member (164), and a coil spring (127) suited for being rotationally pre-stressed by manipulation of the load member (130). When released the coil spring (127) will rotate and undergo a radial contraction which activates the impulse transferring member (164) to squeeze the resilient liquid chamber (143), thereby forcing the contents of the resilient liquid chamber (143) out through the outlet orifice (142).
