    摘要： Presently disclosed is a hydraulic pump device and its use thereof, especially in a fluid delivery system. In one embodiment, the fluid delivery system is an inexpensive, single-use device for slow dosing medicament applications. The fluid delivery system may employ a spring-compressed bellows crank or other combination of simple mechanisms operating according to the well-known peristaltic principle to force a volume of ultrapure bio-inert hydraulic fluid through an aperture, thereby expanding one chamber of a two chamber hydraulic cylinder. The second, fluid storage chamber, containing the medicament, is emptied through a conventional orifice in response to the expansion of the pump chamber. The medicament may thence flow through any suitable infusion set into a patient removeably attached thereto.

    摘要： The invention features an injection device for needles injection. To inject a drug into the body, the oriface (13) of the syringe assembly is pressed against the skin. Thumb pressure is then used to press an injection button (7). This action locks the button in position at detents (16), actuator (4) seats against the chamered end of opening (11). When gas reservoir (6) hits the pointed end of the actuator (4), a seal is ruptured in reservoir (6) thereby releasing the compressed gas contained therein. The gas escapes through the actuator (4) and into an opening (11) where it impinges upon the bottom of floating plunger (10). The plunger (10) pushes against mated pistons (9a, b) thereby expelling the drug through the oriface (13) and into the skin. The entire injection process is completed in less than 2 seconds.
