Abstract

This specimen collection tool can include a handle including a core manufactured by injecting a first material into a mold; wherein the core includes a flat portion, a protrusion and a proximal portion; a distal end having a cavity for receiving the core manufactured by injecting a second material into the mold wherein the second injection is performed without removing the handle from the mold and the second material surrounds the core; a first set of microfeatures disposed on the distal end having a second set of microfeatures disposed on the first set of microfeatures; a demolding pin included in the distal end; a support surface included on the core to support the core in the mold; and, a tapered tip included in the core operatively associated with a narrowing portion of the distal end to hinder removal of the distal end from the handle.

A specimen collection tool comprising

a handle including a core configured to be manufactured by injecting a first material into a mold during a first injection;
wherein the core includes a flat portion, a protrusion and a proximal portion;
a distal end having a cavity for receiving the core configured to be manufactured by injecting a second material into the mold during a second injection wherein the second injection is performed without removing the handle from the mold and the second material surrounds the core;
a first set of microfeatures disposed on the distal end having a second set of microfeatures disposed on the first set of microfeatures;
a demolding pin included in the distal end and wherein the core extends into the distal end past the demolding pin;
a support surface included on the core to support the core in the mold and configured to reduce curving of the core during the second injection;
and,
a tapered tip included in the core operatively associated with a narrowing portion of the distal end to hinder removal of the distal end from the handle.
