Abstract

An alignment guide for hypodermic syringes for facilitating the withdrawal of fluid samples from one or more bottles. The guide assures perpendicular puncturing of a serum bottle septum and provides for easy disassembly for cleaning. The syringe alignment guide includes an inner tube concentrically disposed inside of a tubular housing. The inner tube has first and second ends, and an internal bore for receiving a hypodermic syringe barrel. The first end of the inner tube includes a means for mounting a hypodermic syringe and a means for removably securing the inner tube within the tubular housing. The second end of the inner tube includes a means for mounting a fluid-containing bottle which extends co-axially from the second end of the inner tube and comprises a plurality of protrusions.

Claims

1. A syringe alignment guide comprising:

a tubular housing;

an inner tube having an internal bore for receiving a hypodermic syringe, said inner tube having first and second ends;

means for mounting a hypodermic syringe adjacent to the first end of the inner tube including a portion which protrudes from the periphery of the first end of the inner tube, said portion is parallel to the axis of the inner tube and has a plurality of projections orthogonally positioned relative to the protruding portion;

means for mounting a fluid-containing bottle extending co-axially from the second end of the inner tube including a plurality of protrusions; and

means for removably securing the inner tube within the tubular housing.

2. The syringe alignment guide of claim 1 wherein the means for mounting a fluid-containing bottle comprises three finger-like protrusions.

3. The syringe alignment guide of claim 1 wherein said tubular housing includes a magnifying lens integral with the outer surface of the housing.

4. A syringe alignment guide comprising:

a tubular housing having a first end and a second end;

an inner tube concentrically disposed in said tubular housing having an internal bore for receiving a hypodermic syringe, said inner tube having first and second ends;

means for mounting a hypodermic syringe adjacent to the first end of the inner tube and protruding from the first end of the tubular housing;

means for mounting a fluid-containing bottle extending co-axially from the second end of the inner tube including a plurality of protrusions; and

means for removably securing the inner tube within the tubular housing including an elastomeric O-ring positioned around the outer surface of the first end of the inner tube and over the top portion of the first end of the tubular housing.

5. The syringe alignment guide of claim 4 wherein the inner tube and housing are axially rotatable relative to one another.

6. The syringe alignment guide of claim 4 wherein the means for mounting a fluid-containing bottle comprises three finger-like protrusions.

7. The syringe alignment guide of claim 4 wherein said tubular housing includes a magnifying lens integral with the outer surface of the housing.
