Abstract

See full text

The multidose syringe is provided with two pistons which are attached by a string to move simultaneously. A groove in the barrel for delivering fluid into and from the innermost fluid chamber is provided with baffles to create turbulence in the fluid flow to preclude entry of air into the fluid chamber between the pistons during filling of the syringe.
