Abstract
Abstract An improved hand-held test-tube holder is disclosed. It is a safety device to prevent the contraction by health-care professionals of Acquired Immune Deficiency Syndrome (AIDS), when dealing with infected blood samples. In the preferred embodiment, the invention comprises an oval base; a plurality of vertical shafts for housing vials; and an overlying, horizontal shield. The shield is designed to completely cover the user's cupped hand that grasps the shafts and lifts the holder. It thereby protects that hand from being accidentally pricked by a contaminated needle during the process of drawing blood from an infectious sample in a vial housed in the holder, or during the similar process of depositing a sample into the vial.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
100 words
A hand-held test-tube holder comprising: a. a horizontal base; b. a row of tubular shafts that are integral with the base and which extend vertically therefrom, wherein the shafts are each adapted in size and shape to house a test tube; and c. an overlying horizontal top that is integral with the shafts wider than a user's cupped hand which grasps the shafts to lift the holder, whereby the top acts as a shield to prevent that hand from being accidentally nicked by a needle when a sample is attempted to be drawn from the test tube, or deposited therein.
Claim 2
Dependent Claim
100 words
A hand-held test-tube holder comprising: a. a horizontal base; b. a row of tubular shafts that are integral with the base and which extend vertically therefrom, wherein the shafts are each adapted in size and shape to house a test tube; and c. an overlying horizontal top that is integral with the shafts wider than a user's cupped hand which grasps the shafts to lift the holder, whereby the top acts as a shield to prevent that hand from being accidentally nicked by a needle when a sample is attempted to be drawn from the test tube, or deposited therein.
Claim 3
Dependent Claim
35 words
The test-tube holder of claim 1 wherein each shaft has a frontal slot, which allows a user to press the thumb of his cupped hand against a housed test tube to hold it in place.
Claim 4
Dependent Claim
28 words
The test-tube holder of claim 1 wherein the top has a series of holes that overlie the shafts to allow test tubes to be inserted into the shafts.
Claim 5

Claim 6
Dependent Claim
146 words
A hand-held test-tube holder comprising: a. an elongated base that extends horizontally; b. a plurality of parallel tubular shafts that are integral with the base and which extend vertically therefrom, wherein each shaft is shorter than a test tube yet wide enough to loosely house that tube within it; c. an elongated top that overlies and extends horizontally above the shafts and which is integrally attached to them, said top having a series of holes that align with the shafts to allow test tubes to be inserted into the holder; and d. wherein the top is wider and longer than a user's cupped hand which grasps the shafts to lift the holder, whereby the top acts as a cover to prevent that hand from being accidentally nicked by a needle when a sample is attempted to be drawn from the test tube, or deposited in it.
