ABSTRACT:
An injection device such as a syringe, which has a helical flow path for a solution in which the solvent and solute have been introduced. The helical flow path is formed by a helically configured member which has general overall configuration of a helical coil spring. Individual coils may be formed to have a groove located along the length of the helix. When compressed, the novel member effectively takes on a cylindrical outer configuration. Because the groove is covered and sealed by the surface of the next turn of the helix when compressed, an enclosed helical flow path is formed in the compressed member. The invention may be an injection device using the novel flow path forming member or alternatively, the flow path forming member itself.
