ABSTRACT:
The particular embodiment described herein as illustrative of one form of the invention incorporates a round elongated handle sized for holding in the fisted grip of a person. A shield is positioned on top of the handle and extends radially outwardly therefrom to an extent sufficient to substantially shield the fisted hand of a person gripping the handle. An opening in the center of the shield communicates with a cavity in the handle for receiving a test tube therein. When transferring fluids from a syringe to a test tube, one inserts the test tube into the cavity in the handle and then inserts a syringe needle into the upper end of the test tube with the other hand. If the person performing the operation were to miss the end of the test tube with the needle, the hand of the person holding the device holding the test tube would be shielded from the needle. A ridge on the outer peripheral edge of the shield will pervent a needle from sliding off the edge of the shield should the needle strike the shield.
A sighting window in the handle permits the operator to view the level of fluid transferred into the test tube. An opening on the side of the handle permits the test tube to be contacted from the side of the handle to facilitate its ejection from the cavity in the handle, its being held in the handle while a syringe needle is extracted from the test tube, and the gripping of the handle with the fingers to prevent slippage of the hand from the handle. A small opening in the end of the handle prevents a vacuum from forming between the bottom of the test tube and the bottom of the test tube cavity in the handle.
