Abstract

A syringe assembly is made from a co-extrusion of materials which allows a small volume of fluids or vacuum to be drawn when combined with a plunger. The co-extrusion allows the creation of a syringe assembly by extrusion allowing many varying lengths and sizes, as well as various vacuum ratios. The syringe allows deviations to the vacuum or volume of fluids with minor changes to the inner tubing member and will not change or distort the outer dimensions of the device. The syringe differs from traditional syringes in that it does not rely on exacting measurements to determine incremental movement of the plunger to determine volumes, and does not rely on the exacting conformity of such parts to determine volume. The syringe also differs from conventional syringes since conventional syringes are currently made by traditional molding techniques. The assembly will allow the syringe to be made for collecting and dispensing smaller useful volumes, and will be more ergonomically satisfactory to technicians using the syringe assembly.
