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.

ALIGNMENT GUIDE FOR HYPODERMIC
BACKGROUND OF THE INVENTION 5
1. Field of the Invention
The present invention relates to an alignment guide for hypodermic syringes.
2. Description of the Prior Art
Injectible medications, pharmaceuticals and other
suspensions are typically stored in fluid-containing
serum bottles that have an elastomeric seal or septum
through which a hypodermic syringe needle is intro-
Conventional methods for withdrawing a measured volume of liquid from a serum bottle involve holding the bottle with the fingers of one hand and inserting the needle attached to a hypodermic syringe through the septum by holding the syringe with the other hand. In the case of self-administered medicaments, such as insulin, where the patient may have a limited supply of extra needles, the needle should penetrate the septum at a right angle in order to avoid possibly bending the needle against an inside wall of the serum bottle. For patients who are aged or infirm, the entire manipulative procedure may be difficult. Moreover, certain medical procedures require the injection of a plurality of liquid medicaments from several bottles. Rather than requiring a patient to self-administer a plurality of injections which can be a painful and difficult process, it would be useful to provide a means for easily introducing more than one type of liquid into a single syringe.
While various syringe guides have been available in the prior art, these guides have lacked positive positioning of the serum bottle to assure right angle puncturing of the septum, whether the syringe is inserted into the guide holding the bottle or a new bottle is inserted into the guide holding the syringe. Such guides have also lacked easy locking of the syringe in the guide and easy disassembly of the syringe for cleaning, as required by government (Food and Drug Administration) regulations.
It is therefore an object of this invention to provide an improved syringe guide. Other objects of the invention are to provide a syringe guide with positive positioning for the serum bottle, which can be easily assembled and disassembled.
SUMMARY OF THE INVENTION
According to the present invention, a syringe alignment guide comprises two primary parts: a tubular housing and an inner tube. The inner tube has a first and second end, 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 barrel. The second end of the inner tube includes a means for mounting a fluid-containing bottle.
In its assembled configuration, the syringe alignment guide of the present invention comprises an inner tube concentrically disposed inside of a tubular housing. The inner tube has a first and second end, 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 barrel and a means for securely mounting the inner tube within the tubular housing, that protrude from the first end of the tubular housing. The
second end of the inner tube includes a means for mounting a fluid-containing bottle.
Once the syringe alignment guide of the present invention is in its assembled configuration, a fluid-containing bottle and a hypodermic syringe may be mounted therein. The fluid-containing bottle may be easily detached from the means for mounting the bottle. Therefore, a plurality of fluids may be withdrawn from a series of bottles into a single syringe mounted on the apparatus. The process for providing a plurality of different fluids to a single syringe includes the steps of mounting a hypodermic syringe by inserting it in the first end of the inner tube and into the bore, rotating the syringe barrel so that the barrel flange is locked in the 15 syringe mounting means, and mounting a fluid-containing bottle by pressing the bottle cap into snap-fit engagement with the bottle mounting means. The syringe needle penetrates the bottle through the elastomeric septum located within the bottle cap, and the first fluid 20 is withdrawn into the syringe barrel. The first bottle can then be replaced with a second bottle of the same or different fluid, and because the syringe is aligned in the inner tube, the needle will penetrate the septum of the second bottle in the same manner as the first bottle. 25 Thus, the present invention provides an alignment guide for hypodermic syringes. Moreover, the guide facilitates the withdrawal of fluid samples from a plurality of bottles. The present invention is particularly advantageous for self-administration of these medicaments 30 since only one hand is needed to operate the unit which accommodates both the hypodermic syringe and the bottle. The present invention also assures perpendicular puncturing of the septum, whether the syringe is inserted into the guide holding the bottle or a new bottle 35 is inserted into the guide holding the syringe. The guide of the present invention also provides for easy disassembly for cleaning, as required by government regulations.
Other objects and features of the present invention will become apparent from the following detailed de40 scription when taken in connection with the accompanying drawings which disclose a preferred embodiment of the invention. It is to be understood that the drawings are designed for the purpose of illustration only and are not intended as a definition of the limits of the invention.
45 BRIEF DESCRIPTION OF THE DRAWINGS
The foregoing and other objects and advantages of the invention will be appreciated more fully from the following drawings in which: 50 FIGS. 1A and IB are side views of the tubular housing and the inner tube respectively of a preferred embodiment of the present invention;
FIG. 2 is a side view of the components of FIGS. 1A and IB in assembled form; 55 FIG. 3 is a side view of the assembly of FIG. 2 in use with a hypodermic syringe and a fluid-containing bottle mounted therein.
DETAILED DESCRIPTION OF THE ^ INVENTION
Turning now to the Figures, FIGS. 1A and IB, show side views of a tubular housing 10 and a inner tube 20, respectively, for a preferred embodiment of the present invention. The tubular housing 10 has a first end 11 and 65 a second end 12. Typically, housing 10 is cylindrical and is slightly tapered toward the first end 11 to accommodate inner tube 20. However, housing 10 may also be cylindrical throughout its entire length, or tapered
