Title: Injection pistol for inoculations is operated by compressed gas - with automatic reloading under restoring spring force (BE 11.8.77)
Inventor: CLERC ROBERT
IPC: A61M5/20
Filed: 1976-02-13
Abstract: A press.-injection appts., esp. for inoculations, has the general form of a pistol in which the barrel constitutes the main cylindrical guide for the moving components. At the front end of the 'barrel', is a small batch torage chamber for the quantity of liq. to be injected together with an injection aperture forming its outlet. The press. is applied to this liq. by an axially slidable piston having a small, coaxial duct which acts as the refilling duct for the chamber. Behind this main piton, an axially slidable auxiliary piston transmits the forward thrust from the actuating means providing the injection force. Ths auxiliary piston contains a communicating duct which forms the connection between the supply duct in the main piston and the supply line from the main liqs. reservoir. The front end of the auxiliary piston has a seating, cooperating with a valve cone at the rear end of the main piston. During the forward stroke, the seating and valve cone are in close contact, thus sealing off the liq. supply duct and line leading to the chamber; by contrast, on the return stroke, the main piston initially falls a behind the rearward movement of the auxiliary piston, thus opening a gap between the seating and the valve cone and permitting a renewed supply of liq. to pass to the chamber; immediately following this opening of the valve, the main piston follows the rearward movement of the auxiliary piston, as a result of the press. of the liq. at the nozzle end in the chamber. Used as an intradermic injection appts. for inoculations and vaccinations, in partic. for use by relatively unskilled persons, for example in developing countries. The appts. is simple to maintain, reliable in use and extremely easy to operate.
