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, Figure 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 Figures 1A, I B 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] Figure IB 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 oh the material from which it is fabricated.
[003$] As illustrated in Figures 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 Figure 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 anipoule 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 Figure 5,
[0045] A second variation of the ampoule sheath 30 is illustrated in Figure 6.
As seen here, the ampoule sheath 30a" does not extend the full length of the ampoule 40a.
[0046] Figures 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 Figures 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 compiimentarily 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 mat 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 oft the medical ampoule, generally by sliding the ampoule sheath ever the medical ampoule.
[0053] Step 3 - break the breakaway top of die 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 the 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 Figure 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 Figures 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.
