Description
The tool of the instant invention has been primarily designed for
administering liquid as well as tablet and capsule medicants to
felines. It is very difficult to administer oral medicants to cats.
In most cases when capsule or tablet medicants are to be
administered the tablet or capsule must be placed in the back of
the cat's mouth with the fingers. This of course presents one or
more of the fingers of the person administering the medicants in
full exposure to the fangs of the cat which can result in those
fingers being bitten. In addition, placement of the hands of the
person administering medicants to felines closely adjacent to the
head of the feline also presents the hand in eacy reach of the
front claws of the feline.
It is accordingly the main object of this invention to provide a
tool for administering medicants to felines with the tool
constructed and operational in a manner whereby the person
administering the medicants may maintain their hands out of reach
of the fangs or front claws of the felines.
Another object of this invention is to provide a tool whereby
capsule and tablet medicants may be more efficiently placed in the
back of the mouth of a cat so as to ensure that the cat will not
repeatedly spit out the medicant being administered.
Another object of the present invention, in accordance with the
immediately preceding object, is to provide an elongated medicant
administering tool including a soft tip for insertion into the back
of the mouth of the feline having medicants administered thereto
whereby there will be little chance of injury to the feline.
Still another object of this invention is to provide a tool in
accordance with the preceding objects that may be readily
dismantled for cleaning and sterilizing.
Another important object of this invention is to provide a tool
including structural and operational features enabling the tools to
be utilized by untrained personnel as well as professionals.
A final object of this invention to be specifically enumerated
herein is to provide a medicant administering tool specifically
designed for use in conjunction with felines and which will conform
to conventional forms of manufacture, be of simple construction and
easy to use so as to provide a device that will be economically
feasible, long lasting and relatively trouble free.
These together with other objects and advantages which will become
subsequently apparent reside in the details of construction and
operation as more fully hereinafter described and claimed,
reference being had to the accompanying drawings forming a part
hereof, wherein like numerals refer to like parts throughout, and
in which:
FIG. 1 is a perspective view of the tool in its form for
administering capsule and tablet medicants;
FIG. 2 is a longitudinal sectional view taken substantially upon a
plane passing through the longitudinal center line of the tool;
FIG. 3 is a fragmentary sectional view comprising an enlargement of
the left hand portion of FIG. 2 and with a tablet supported within
the split sleeve portion of the tool and the plunger of the tool
disposed immediately adjacent to the tablet for expelling the
latter from the split sleeve tool portion;
FIG. 4 is a perspective view of a squeeze bulb attachment for the
tool for adapting the latter to administer liquid medicants upon
removal of the plunger and the split sleeve portion of the
tool;
And FIG. 5 is a side elevational view of the tool with the squeeze
bulb attachment applied thereto, portions of the main sleeve body
of the tool being broken away and illustrated in vertical
section.
Referring now more specifically to the drawings the numeral 10
generally designates the animal pill administering tool of the
instant invention. The tool 10 includes an elongated tubular body
12 including first and second ends 14 and 16 and provided with a
longitudinal bore 18. The bore 18 extends through the body 12 and
is of substantially constant diameter, except in the first end 14
of the body 12 wherein the bore is slightly tapered as at 20.
The second end 16 of the body 12 includes a circumferentially
extending and slightly radially outwardly projecting retaining
flange 22 and also a considerably diametrically enlarged portion 24
spaced slightly toward the first end 14 from the retaining flange
22. The diametrically enlarged portion 24 includes a wide and
relatively deep circumferentially extending semi-circular groove
26.
An elongated plunger 28 is reciprocal through the bore 18 and
includes a diametrically enlarged head 30 on its end projecting
outwardly of the second end 16 of the body 12. The head 30 is
circular in cross sectional shape and the end of the plunger 28
remote from the head 30 includes a diametrically reduced terminal
end 32 for reciprocation through the tapered end of the bore 18
formed in the first end of the body 12.
A resilient and slightly radially expandable sleeve 34 is provided
and has a first end 36 thereof telescoped over and frictionally
retained on the end 14 of the body 12. The second or other end 38
of the sleeve 34 is provided with circumferentially spaced and
longitudinally extending tapered slots 40 which render the second
end 38 of the sleeve 34 more readily expandable than the end 36 of
the sleeve 34. The slots 40 taper in width inwardly of the terminal
end of the second end 38 of the sleeve 34 and it may be seen from
FIG. 3 of the drawings that a pill or capsule 42 may be
frictionally seated between the resilient fingers 44 defined
between adjacent slots 40.
In operation, with the pill or capsule 42 frictionally retained
between the fingers 44 and the plunger 28 withdrawn to the position
thereof illustrated in FIG. 3 of the drawings, a person wishing to
administer the pill or capsule to an animal such as a feline may
project the first end 14 of the body 12 into the mouth of the
animal with the resilient slotted end of the sleeve 34 disposed in
the back of the animal's mouth.
In manipulating the tool 10, the first and second fingers of the
hand holding the tool are seated in diametrically opposite portions
of the groove 26 in order to firmly support the tool 10 from the
hand. Then, firm pressure is applied to the head 30 to advance the
plunger 28 to the left as viewed in FIG. 2 of the drawings whereby
the diametrically reduced terminal end 32 of the plunger 28 will
forcibly eject the pill or capsule from the slotted end of the
sleeve 34.
By this manner of administering a pill or capsule to a feline, the
hand holding the tool 10 is positioned outwardly of the front of
the mouth of the feline and out of reach of the claws carried by
the front legs of the feline. Therefore, there is little likelihood
of the person administering the pill or capsule 42 being bitten or
scratched by the feline.
With attention now invited more specifically to FIGS. 4 and 5 of
the drawings, there may be seen a resilient squeeze bulb referred
to in general by the reference numeral 50. The squeeze bulb 50 is
closed at one end 52 and open at its other end 54. In addition, the
other end of the squeeze bulb 50 is provided with a radially
outwardly projecting and circumferentially extending reinforcing
rib 56 whereby the open end 54 of the squeeze bulb 50 may be
slightly expanded over the end 16 of the body 12 with the flange 56
disposed inwardly of the retaining flange 22. In this manner, even
though the first end 52 of the squeeze bulb 50 is squeezed, the
bulb 50 will be frictionally retained on the end 16 of the body 12
in fluid tight engagement therewith.
The body 12 is constructed of transparent material such as plastic
and has longitudinally spaced indicia 58 thereon adjacent the first
end 14. Accordingly, by removal of the plunger 28 and the
application of the squeeze bulb 50 on the end 16 of the body 12,
the tool 10 may be utilized in the manner of an eye dropper whereby
measured portions of liquid medicants may be administered to
felines.
The foregoing is considered as illustrative only of the principles
of the invention. Further, since numerous modifications and changes
will readily occur to those skilled in the art, it is not desired
to limit the invention to the exact construction and operation
shown and described, and accordingly all suitable modifications and
equivalents may be resorted to, falling within the scope of the
invention.
