Abstract:
PCT No. PCT/SE94/00864 Sec. 371 Date Mar. 27, 1996 Sec. 102(e) Date Mar. 27, 1996 PCT Filed Sep. 16, 1994 PCT Pub. No. WO95/09020 PCT Pub. Date Apr. 6, 1995An injection cartridge is disclosed which has provision for the after injection of a rinsing solution to wash off the medicament that is first injected. The novel cartridge has a forward compartment and a rearward compartment, each having a piston disposed rearwardly thereof. A by-pass conduit is provided at the forward end of the cartridge which is longer than the thickness of the forwardmost piston. A medicament is positioned in the forward compartment and a rinsing solution is positioned in the rearward compartment. Moving the rearward piston forward forces the rinsing solution against the forward piston which in turn forces the medicament forward and expels it from the forward compartment. After the forward piston has reached its forward stop, the forward by-pass becomes open to the rearward compartment and continued forward movement of the rearward piston causes the rinsing solution to be forced through the forward by-pass and out the outlet end of the cartridge. This arrangement is particularly useful where the outlet is a tube and an injection needle or cannula.
