Reich Atzorneylessup & Beecher ABSTRACT: An improved guide is provided for use with hypodermic syringes so as to facilitate the loading of the syringe from a bottle containing a drug, medicine, or other liquid. The improved guide has utility for both sighted and blind persons, since it permits the syringe to be held in proper relationship with the neck of the bottle containing the liquid, and since it serves to guide the needle part of the syringe through the cap and into the bottle a proper distance so as to assure the correct dosage. The guide may also include an adjustable stop member which serves to limit the loading stroke of the plunger part of the syringe so that a predetermined amount of the liquid is drawn into the syringe without the need for the careful reading of scales, calibrations or the like.

SYRINGE GUIDE AND INDICATOR BACKGROUND OF THE INVENTION It is often difficult for both sighted and blind persons to use hypodermic syringes of the usual prior art type. Even nurses or other trained personnel find the administration of drugs by a hypodermic syringe to be a somewhat painstaking operation, since in each instance, they must be sure that the proper dose is drawn into the syringe, and this is usually ascertained by the careful reading of scales and calibrations on the wall of the barrel part of the syringe. The task of self-administration of drugs in correct dosages is almost impossible for blind persons, yet a large number of the blind suffer from ailments and diseases, such as diabetes, which require periodic hypodermic injections of insulin, and the like.

A primary object of the present invention is to provide an improved guide which may be used in conjunction with standard hypodermic syringes, and with the standard sealed bottles containing the liquids to be administered by such syringes. The guide of the invention serves to hold the hypodermic syringe and the bottle in a firm and properly aligned relationship so as to enable the hypodermic needle to be pierced through the sealed cap of the bottle, and inserted into the neck of the bottle the proper distance to assure that a full dosage is drawn into the syringe from the bottle, even though the contents may not actually be observed. The guide also may include an adjustable limit stop, as mentioned above, so that the amount of liquid drawn into the barrel of the syringe may be precisely predetermined. For example, this stop may be set initially at a particular setting, and then without any further reading, the correct dosage may be drawn into the barrel of the syringe each subsequent time the assembly is used.

Another object of the invention is to provide such an improved guide which is simple and inexpensive in its construction, and which is easy to use. The guide of the invention is light and does not add in any measurable way to the weight of the syringe and bottle. Moreover, the guide is constructed so that it in no way interferes with the ease of operation of the syringe. Also, both the bottle and the syringe may easily be removed from the guide after each use and disposed of, and the guide may be retained for subsequent use.

SUMMARY OF THE INVENTION A guide for a hypodermic syringe is provided which may be attached to the neck of a standard drug bottle and which holds the bottle and a standard syringe in proper aligned relationship with one another. The guide serves to permit the hypodermic needle of the syringe to be easily inserted through the cap of the bottle and into the bottle by a proper amount so that a full dosage is assured. In addition, the guide may incorporate an adjustable stop which may be initially set, and thereafter predetermines the amount of liquid which is to be drawn into the barrel of the syringe for each subsequent use of the guide.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective representation of one embodiment of the guide of the invention, and of a hypodermic syringe and bottle which may be supported by the guide,

FIG. 2 is an elevational representation of the guide, syringe and bottle, including a side sectional view of the guide, showing the syringe and bottle in place, with the bottle being shown as partially broken away to illustrate more clearly the manner in which the syringe pierces the cap of the bottle and enters the neck thereof FIG. 3 is a exploded perspective view of a second embodiment of the invention, and showing one of the components thereof removed from the central body portion; and FIG. 3A is a perspective representation of a modified form of guide of the invention; and

FIGS. 4A, 4B and 4C are side elevational views showing the various positions in the use of the embodiment of FIG. 3 in conjunction with a hypodermic syringe.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS The guide shown in FIG. 1 includes an elongated trough like body portion 10 which is adapted to receive a standard syringe 12 in coaxial relationship. The standard syringe 12 includes a barrel l2aand a hypodermic needle 12b, and it also includes a plunger l2cwhich extends into the barrel, and which may be moved axially with respect to the barrel by means of an actuating knob 12d. The barrel l2aalso includes a peripheral flange l2e,all of the aforesaid components being standard parts of a usual present day hypodermic syringe.

The body portion 10 has an integral end portion l0aat the end to the right in FIG. 1, and the end portion 10a defines a transverse channel which receives the flange 12eas best shown in FIG. 2, so as to support the syringe 12 in the body portion 10. The syringe is so supported in a readily removable manner, but against any longitudinal movement within the body portion due to the channel formed by the end portion 100, and against radial movement by the configuration of the body portion 10 itself.

The troughlike body portion 10 has a second end portion at the opposite end thereof, and this second end portion 10bdefines a diametrically enlarged cavity for receiving the head of a bottle 14, and for holding the bottle firmly and securely in, for example, a press friction fit. However, as was the case with the syringe 12, a bottle 14 may be readily removed from the guide, when so desired.

The bottle 14 may be of the type usually provided for containing drugs, and the like. It includes on its head a metal cap with a central opening, and a rubber diaphragm sealing the opening. The diaphragm is pierced by the hypodermic needle 12b, and the contents of the bottle may then be drawn into the barrel l2aof the hypodermic syringe 12.

It will be appreciated that the guide described above provides a simple and expeditious means for supporting the bottle 14 and the syringe 12 in an aligned manner, so that the needle 12dmay be inserted into the bottle 14, merely by moving the plunger l2cdown into the barrel 12a. Also, the bottle any syringe are held at predetermined spaced positions by the guide, so that the needle l2dextends the proper distance into the bottle l4, and not too far, so as to assure a full dosage when the syringe is loaded.

The guide 10 described above may be formed by a simple molding operation of any appropriate plastic material, with the end portions l0aand l0bformed integral with the central trough like portion. The other'guides to be described herein may also be formed of appropriate plastic.

For example, the guide 20 of FIG. 3 includes a U-shaped body portion having resilient characteristics, and which is transversely slotted to receive the flange l2eof the hypodermic syringe 12, as shown in FIGS. 4A, 4B and 4C. The guide 20 also includes a slotted bore 21 which receives a rod like stop member 22. The rod like stop member 22 is slidable in the bore 21. The stop member 22 may be moved axially in the bore 21, and yet it is supported in a relatively close press fit by the body portion.

The rod like stop member may include a plurality of peripheral grooves 22a, for the convenience of blind persons, and these grooves contact a peripheral ridge of conventional form within the bore 21. Then, as the stop member 22 is moved back and forth in the bore 21 to a preset position, the axial movement thereof may be determined by the clieking" action between the ridge and the successive grooves 22a.

For the sighted person, the guide may take the form shown in FIG. 3A in which it is designated 20a. The guide 200 is similar to the guide 20 except that the bore 21ais not slotted and a setscrew 23 is provided. For the latter guide, the stop member 22 is not grooved, and it may be locked in any position by the sighted person, merely by tightening the setscrew 23.

The rod like stop member 22 has a radially extending and portion 22bat its free end. As shown, for example, in FIGS. 4A, 4B and 4C, the stop member 22 may be withdrawn from the body portion to any desired setting (as set by the selected groove in FIG. 3 or as locked by the set screw 23 in F IG. 3A), and then turned so that its end portion 22bacts as a stop for the actuating knob l2dof the plunger 12cof the syringe 12.

The first step in the procedure, as shown in FIG. 4A, is to move the plunger down into the barrel l2aof the syringe 12, so that the hypodermic needle 12b may pierce the cap and enter the neck of the associated bottle (not shown). Then, the plunger l2cis drawn back until the actuating knob l2dmeets the end portion 22bof the stop member 22, as shown in FIG. 48. At this point the predetermined amount of liquid has been drawn into the barrel of the syringe 12. The stop member 22 may then be turned so that its end portion 22bis out of the way, as shown in F [(3. 4C, and the syringe is then ready for the injection to be made.

It will be appreciated that once a desired setting is established for the stop member 22, the assembly may be used over and over again, without the need for any further setting. In each instance, exactly the proper dosage is drawn into the barrel of the syringe 12 for the injection.

The invention provides, therefore, an improved, inexpensive and sturdy guide which has utility for supporting a hypoden'nic syringe and bottle in proper relationship, so that the hypodermic needle associated with the syringe may be easily and expeditiously inserted into the bottle. Moreover, the improved guide of the present invention may be constructed to incorporate an adjustable stop member, so that a predetermined dosage may be drawn into the syringe in a simple and convenient manner.
