Abstract
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.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
152 words
Apparatus for providing a safety shield to an operator in the process of transferring body fluids from a syringe to a test container which comprises: a handle for holding the safety shield in the hand of an operator, said handle having the form of an elongated, substantially cylindrical member with a longitudinal dimension which is sufficient to extend transversely across the palm of the operator's hand and having formed therein a longitudinal cavity within the substantially cylindrical member that is long enough to receive the greater part of a test container lengthwise, said cavity being sized for securely holding the test container and a shield extending radially outwardly from the upper end of the handle to a distance such that when the handle is grasped within the operator's palm to form a clenched fist about the handle, the bottom surface of the shield substantially covers the upper side of the clenched fist.
Claim 2
Dependent Claim
152 words
Apparatus for providing a safety shield to an operator in the process of transferring body fluids from a syringe to a test container which comprises: a handle for holding the safety shield in the hand of an operator, said handle having the form of an elongated, substantially cylindrical member with a longitudinal dimension which is sufficient to extend transversely across the palm of the operator's hand and having formed therein a longitudinal cavity within the substantially cylindrical member that is long enough to receive the greater part of a test container lengthwise, said cavity being sized for securely holding the test container and a shield extending radially outwardly from the upper end of the handle to a distance such that when the handle is grasped within the operator's palm to form a clenched fist about the handle, the bottom surface of the shield substantially covers the upper side of the clenched fist.
Claim 3
Dependent Claim
22 words
The apparatus of claim 1 wherein the upper side of the shield has an upwardly extending shoulder about the outer edge thereof.
Claim 4
Dependent Claim
24 words
The apparatus of claim 1 wherein the shield is a substantially flat disc having at least one flat surface on its outer circumferential edge.
Claim 5
Dependent Claim
164 words
Apparatus for providing a safety shield to an operator in the process of transferring body fluids from a syringe to a test container which comprises: a handle for holding the safety shield in the hand of an operator, said handle having the form of an elongated, substantially cylindrical member with a longitudinal dimension which is sufficient to extend transversely across the palm of the operator's hand and having formed therein a longitudinal cavity within the substantially cylindrical member that is long enough to receive the greater part of a test container lengthwise, said cavity being sized for securely holding the test container and a shield extending laterally outward from the upper end of the cavity in the handle, and further including an opening in the side of the cylindrical member for communicating the interior of the cavity within the handle to the outside surface of the handle for permitting contact with a test container in the cavity from the side of the cylindrical member.
Claim 6
Dependent Claim
164 words
Apparatus for providing a safety shield to an operator in the process of transferring body fluids from a syringe to a test container which comprises: a handle for holding the safety shield in the hand of an operator, said handle having the form of an elongated, substantially cylindrical member with a longitudinal dimension which is sufficient to extend transversely across the palm of the operator's hand and having formed therein a longitudinal cavity within the substantially cylindrical member that is long enough to receive the greater part of a test container lengthwise, said cavity being sized for securely holding the test container and a shield extending laterally outward from the upper end of the cavity in the handle, and further including an opening in the side of the cylindrical member for communicating the interior of the cavity within the handle to the outside surface of the handle for permitting contact with a test container in the cavity from the side of the cylindrical member.
Claim 7
Dependent Claim
28 words
The apparatus of claim 4 including means in the side of the handle for observing at least a portion of a test container when positioned within the cavity.
Claim 8
Dependent Claim
34 words
The apparatus of claim 1 wherein the cavity has means forming a top opening for receiving the test container and further including an opening in the bottom of the cavity opposite the top opening.
Claim 9
Dependent Claim
174 words
Apparatus for facilitating the holding of a test tube in a person's hand while transferring fluids from a syringe which has a needle for taking and dispensing body fluids into and from the syringe and for protecting the person's hand from contact by the needle which comprises: an elongated handle sized to be held in a person's hand with the palm and fingers closed about the handle to create the form of a fist; a cavity formed within the handle and sized to receive a test tube, said cavity being in a cylindrical shape having an open upper end, said cylindrical cavity being sized to matingly receive and securely hold the test tube and having a length such that when the test tube is fully inserted into the cavity, the upper end of the test tube projects above the upper open end of the cavity in the handle; and a shield on said handle for shielding a hand closed about the handle when the contents of a syringe are transferred into the test tube.
