ABSTRACT:
The syringe has an outer casing open at one end and a cylinder reciprocable within the casing in which latter works a plunger; the cylinder is spaced from the inner periphery of the casing to form an outer chamber and the space within the cylinder forms an inner chamber, each chamber to contain the ingredients to be mixed to form a composition for injection; means being provided at the discharge end of the casing for the attachment of a needle for injection; sealing means at the open end of the casing are extended outwardly along the cylinder to protect the exterior of the cylinder from contamination during its withdrawal for the purpose of mixing. In another form the discharge end of the cylinder is adapted to be extended through the discharge sealing gland to receive the syringe needle; the sealing gland at the discharge end of the cylinder has suitable spiral grooves facing the cylinder so that when the cylinder is retracted its nozzle end discharges into the spiral grooves; the inner and outer chambers are of such capacity that when the cylinder is in mixing position and when the cylinder is retracted to locate the nozzle, it enlarges the capacity of the outer chamber creating suction to facilitate the discharge of the contents of the inner chamber by the plunger without producing undue pressure in the outer chamber, a negative or vacuum effect is created within the combined inner and outer chamber environment when the cylinder is in mixing position.
