DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0031] The present invention is a syringe for direct use with
medical ampoules and vials that includes an ampoule sheath and in
which the syringe plunger is configured to accept insertion of the
ampoule with an ampoule sheath deployed thereon.
[0032] The principles and operation of a syringe for direct use
with medical ampoules and vials according to the present invention
may be better understood with reference to the drawings and the
accompanying description.
[0033] By way of introduction, it will be understood that numerous
devices are in use today to aid users in safely breaking breakable
medical ampoules. Likewise, there are syringe devices for use in
extracting medicines from the broken ampoule. The syringe of the
present invention comes to address both of these issues in a single
device.
[0034] Referring now to the drawings, FIG. 1A illustrates a first
preferred embodiment of the ampoule sheath 30 of the present
invention that is directed to use with a breaking ampoule 40.
[0035] As illustrated in FIGS. 1A, 1B and 1C, the ampoule sheath 30
of the present invention is deployed on breakable ampoule 40 such
that the bottom portion 30a of the ampoule sheath 30 is deployed on
the medicine containing bottom portion 40a of the ampoule and top
portion 30b of the ampoule sheath 30 is deployed on the top
breakaway portion 40b of the ampoule with the "break lines" 32 of
the ampoule sheath 30 aligned with the break line of breakable
ampoule 40.
[0036] FIG. 1B illustrates the bottom portion 30a of the ampoule
sheath 30 is deployed on the medicine containing bottom portion 40a
of the ampoule after breaking.
[0037] It will be appreciated that the ampoule sheath 30 can be
fabricated from substantially any suitable material and variant
embodiments may be rigid, brittle, pliable, flexible or elastic.
When breaking the top off of the ampoule, the ampoule sheath 30 may
be configured to break or tear along the "break line", depending on
the material from which it is fabricated.
[0038] As illustrated in FIGS. 2a and 2B Syringe 2 includes a
syringe body 10 and a syringe plunger 20.
[0039] The syringe plunger 20 is configured with a hollow interior
volume 24 which is open at one end 22.
[0040] Among the unique features of the present invention, as
illustrated here, is the deployment of the medicine containing
portion 40a of breaking ampoule 40 directly in the hollow volume 24
of the syringe plunger 20. Once deployed, the medicine contained in
the ampoule is drawn into the barrel 12 of the syringe body 10
through passageway 28 in the syringe plunger 20 by vacuum pressure
that is created when the plunger 20 is drawing out of the syringe
body 10 as illustrated in FIG. 2B. The use of passages and one way
valves to allow ambient air pressure into the ampoule as the liquid
is drawn out is well known in the art and will not be addressed
herein.
[0041] To assist in the secure deployment of the ampoule 40a in the
hollow volume 24 of the syringe plunger 20 an ampoule sheath 30 is
provided. The ampoule sheath 30, therefore, acts as an ampoule
interface element deployed between an outer surface of the ampoule
40a and the surface of the hollow interior volume 24 so as to hold
the medical ampoule 40a in the hollow interior volume.
Additionally, but not necessarily, the ampoule sheath may provide a
seal between the ampoule 40a in the hollow volume 24 of the syringe
plunger 20.
[0042] As discussed above, the ampoule sheath 30 is configured for
deployment on the ampoule prior to insertion of the ampoule into
the hollow volume 24. It will be appreciated that ampoule interface
that is deployable in the hollow volume 24 prior to insertion of
ampoule is considered within the scope of the present
invention.
[0043] Returning now to the Figures, the ampoule sheath 30 is
configured with an inside surface having a diameter 34 equal to an
outside diameter of the ampoule 40 and an outside surface having
diameter 36 equal to an inside diameter of the hollow interior
volume 24 of the syringe plunger 20. Configured thusly, the inside
surface 34 interacts with an outside surface of the ampoule 40 and
the outside surface 36 interacts with an inside surface of the
hollow interior volume 24 of the syringe plunger 20.
[0044] Due to the numerous variations on sizes on medical ampoules,
especially diameters, the syringe plunger 20 is manufactured such
that the inside diameter of the hollow volume 24 is constant and
the thickness of the wall 38 of the ampoule sheath 30 is varied to
accommodate the size of the ampoule to be used. Therefore, the
ampoule sheath 30 serves to adapt the size of the medical ampoule
40 to fit snugly into the generic size of the hollow volume 24.
This first variation of the ampoule sheath 30a is best illustrated
in FIG. 5.
[0045] A second variation of the ampoule sheath 30 is illustrated
in FIG. 6. As seen here, the ampoule sheath 30a does not extend the
full length of the ampoule 40a.
[0046] FIGS. 3A and 3B illustrate a second preferred embodiment of
the syringe of the present invention, it will be understood that
elements shown here that correspond to elements of the first
preferred embodiment of FIGS. 2A and 2B are numbered the same. As
illustrated here, the outside diameter 36 of the ampoule sheath 30a
and the inside diameter of the hollow interior volume 24 of the
syringe plunger 20 are complimentarily varied along their common
length, so as to enhance the interface action by increasing
friction between the ampoule sheath 30a and the surface of the
hollow interior volume 24, and thereby provide a better fit between
the two elements.
[0047] As shown herein, the variance in the inside diameter of the
hollow interior volume is illustrated as a step change in area 26
of the syringe plunger. However, it should be understood that this
illustration is not intended as a limitation to such a design and
that substantially any variation of the outside diameter 36 of the
ampoule sheath 30 and the inside diameter of the hollow interior
volume 24 of the syringe plunger 20 along their common length is
within the scope of the present invention.
[0048] It will be appreciated that the tip of the syringe barrel 12
is configure to receive a standard medical needle for injection of
the medicine draw from the ampoule, as is well known in the
art.
[0049] Due to the numerous variations on sizes on medical ampoules,
especially diameters, the syringe together with the ampoule sheath
may be provided to the user as a kit containing a syringe body, a
syringe plunger configured with a generically sized hollow interior
volume and a plurality of ampoule sheaths of varying sizes so as to
accommodate use with a range of differing sizes of medical
ampoules.
[0050] The steps for use of the syringe kit of the present
invention are as follows:
[0051] Step 1--choose an ampoule sheath of the correct size for the
medical ampoule to be used.
[0052] Step 2--deploy the ampoule sheath on the medical ampoule,
generally by sliding the ampoule sheath ever the medical
ampoule.
[0053] Step 3--break the breakaway top of the medical ampoule
together with the top portion 30b of the ampoule sheath 30.
[0054] Step 4--insert the medicine containing bottom portion 40a,
with the bottom portion 30a of the ampoule sheath still deployed
thereon, into the hollow interior volume 24 of the plunger 20 with
the open end of the ampoule facing into he hollow interior volume
24.
[0055] Step 5--draw the plunger 20 out of the syringe body so as to
draw medicine from the ampoule into the barrel 12 of the syringe
body.
[0056] Step 6--attach an injection needle to the tip of the barrel
12 of the syringe body.
[0057] Step 7--inject the medicine.
[0058] Regarding the numerous variations in size of medical vials
in use today, the current state of the art is directed to devices
that are dedicated to a particular size. Therefore, as illustrated
in FIG. 7, the feature of the sheath, here a vial sheath 90, of
this embodiment 50 of the present invention may be used to benefit
as an interface element for adapting substantially any size medical
vial 80 for use with the standardized diameter of the hollow
interior volume 74 of the syringe plunger 70.
[0059] It will be readily understood that once the vial 80, with
the vial sheath 90 deployed thereon, is inserted into the hollow
interior volume 74 the operation of this embodiment is essentially
the same as that of the embodiment of FIGS. 2A and 2B.
[0060] It will be appreciated that the above descriptions are
intended only to serve as examples and that many other embodiments
are possible within the spirit and the scope of the present
invention.
