SYRINGE GUIDE AND INDICATOR
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.

Description
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.

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
12aand a hypodermic needle 12b, and it also includes a plunger
12cwhich extends into the barrel, and which may be moved axially
with respect to the barrel by means of an actuating knob 12d. The
barrel 12aalso includes a peripheral flange 12e,all of the
aforesaid components being standard parts of a usual present day
hypodermic syringe.
The body portion 10 has an integral end portion 10aat 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 10a, 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 12aof 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 12cdown
into the barrel 12a. Also, the bottle any syringe are held at
predetermined spaced positions by the guide, so that the needle
12dextends the proper distance into the bottle 14, 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 10aand 10bformed 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 12eof 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 "clicking" 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 20a 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 20 to any
desired setting (as set by the selected groove in FIG. 3 or as
locked by the set screw 23 in FIG. 3A), and then turned so that its
end portion 22bacts as a stop for the actuating knob 12dof 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 12aof 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 12cis drawn back
until the actuating knob 12dmeets the end portion 22bof the stop
member 22, as shown in FIG. 4B. 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 FIG. 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 hypodermic 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.
