The ampoule snapper and hypodermic needle remover, comprising two clamp arms having confronting faces, ampoule head engaging means on the confronting faces of the clamp arms, biasing means biasing the clamp arms to an open position for the reception of an ampoule head or hypodermic needle there between and finger engaging portions on the clamp arms for engagement by a user's fingers to close the clamp arms against the bias of the biasing means so as to grip the ampoule head or hypodermic needle there between. The body of the ampoule or hypodermic syringe can be grasped in one hand and the ampoule head or hypodermic needle engaged between the two clamp arms. The application of torque to the ampoule head then breaks off the ampoule head at the neck, the application of rotation to the hypodermic needle removes the hypodermic needle from the hypodermic syringe. The sharp edges are not in the vicinity of the user's hands, reducing the risk of cuts. The hypodermic needle is not in the vicinity of the users hands reducing the risk of injury. Where the ampoule head engaging means are contoured to fit the head of the ampoule by means of confronting grooves, the ampoule head itself is not broken and the two-separated glass components are readily discarded into a Sharps container.
Where the hypodermic needle engaging means, are normally but not necessarily a straight face resilient block, the hypodermic needle can be engaged and be removed and readily discarded into a Sharps container.
Where the hypodermic needle engaging means, are normally but not necessarily a straight face resilient block, the hypodermic needle can be engaged and be removed and readily discarded into a Sharps container.
Description
AMPOULE SNAPPER AND HYPODERMIC NEEDLE REMOVER
FIELD OF THE INVENTION
The present invention relates to a re-useable device that can easily be disassembled and assembled to facilitate thorough sterilization and is used for removing the heads of glass ampoules and removing hypodermic needles from hypodermic syringes by using interchangeable resilient blocks to suit the application.
BACKGROUND
Glass ampoules are used for containing liquids, especially medicines prepared for injection.
These containers have two parts, a main body for containing the liquid and a break-off head joined to the body by a frangible neck. For access to the liquid contents, the body and neck are normally gripped by the two hands of the user and torque is applied to break off the head from the body. This produces broken glass with sharp edges and frequently results in cuts to the hands of the person opening the glass ampoule.
The removal of hypodermic needles from hypodermic syringes also causes injury.
Replacing the resilient blocks to a straight face resilient block on the instrument will enable the device to remove hypodermic needles and eliminate hypodermic needles to be removed by hand reducing injuries.
The ability to replace resilient blocks of various designs broadens the range of functionality of the device.
The need to have a device that can easily be disassembled and assembled to facilitate thorough sterilization is required in sterile medical environments.
The present invention proposes a device that addresses these problems.

DETAILED DESCRIPTION
Referring to the accompanying drawings, there is illustrated an ampoule snapper and hypodermic needle remover 10 according to the present invention. The ampoule snapper and hypodermic needle remover 10 has an arm 12 with hinge hook 18 upstanding from one side of the arm 12 at one end.
A second arm 16 likewise has hinge support pillars 19 projecting from one side at one end. The support pillars 19 are joined by lateral axle or a removable axle 20 so that the arms 12,16 can pivot with respect to one another around the axle 20. The axle 20 can also be a fixture between support pillars 19 or it can be a removable axle 20 that can be re-installed to facilitate assembly and disassembly to enable improved sterilization. A spring or resilient block 22 biases the arms 12,16 to an open position as illustrated in Figures 2 and 3. The spring or resilient block 22 biasing the arms 12,16 apart are positioned between the arms 12,16. Each of the arms 12,16 carries a resilient block 24 that can be rubber or any other compounded material with the necessary characteristics on the face confronting the other arm. The blocks 24 have respective small grooves 26 that confront one another and large grooves 28 that also confront one another.
Both pairs of grooves 26,28 extend laterally across the arms 12,16, parallel to the axle 20. The resilient blocks 24 can also have a single groove with a cavity 53 inside that will enable the side walls 52 to collapse and conform to large and small ampoule heads as illustrated in Figure 7.
The resilient blocks 24 can also have a straight face 55 without grooves with a cavity 53 inside that will enable the sidewalls 52 to collapse and conform to large and small ampoule heads as illustrated in Figure 8. The grooved resilient blocks 24 can also be interchanged with straight-faced resilient blocks 55 as illustrated in figure 8 to facilitate the removal of hypodermic needles 56. It is to be understood that different designed resilient blocks 24 can be used to facilitate the removal of both hypodermic needles 56 and ampoule heads 36 and 34. It is possible but not necessary to use one set of resilient blocks 24 that can achieve both mentioned tasks.
As illustrated in Figure 1, each arm has an enlarged head 30 at the end opposite the axle 20. This provides for the convenient engagement of the arm with the fingers and thumb of one's hand.
The enlarged head 30 on arm 16 have an arm slip control protrusion 47 that will engage the arm slip control groove 48 in the enlarged head of arm 12 to prevent the arms from slipping out of alignment when torque is applied to snap an ampoule head. When the arms are locked in the slip control groove 48 the closure of the arms are limited to prevent excessive pressure to be applied on the ampoule head causing it to shatter (Figure 4).
Figures 1 and 2 illustrate the manner in which an ampoule is gripped prior to being opened using the ampoule snapper and hypodermic needle remover 10. A first ampoule 32 has a body 34 containing a liquid. A head 36, made of the same glass material as the ampoule body 34, projects from one end of the ampoule 32 and is joined to it by a neck 38. In use, the head 36 is inserted between the appropriately sized pair of grooves 26 and the ampoule snapper and hypodermic needle remover 10 is closed by bringing the two arms 12,16 together and clamping the ampoule head 36 between the two resilient blocks 24. The ampoule snapper and hypodermic needle remover 10 and the body 34 of the ampoule 32 can then be manipulated to break the head 36 from the ampoule 32 at the neck 38. Figures 1 and 2 illustrate a second ampoule 40 of a larger size than the first ampoule 32. The body 42 of the ampoule 40 and the head 44 are manipulated in the same way as the body 34 and head 36 of the first ampoule 32, this time using the larger grooves 28 in the blocks 24 to snap the head 44 of the second ampoule 40 off at the neck 46.
Figures 9 and 10 illustrate the manner in which a hypodermic needle 56 is gripped prior to being removed using the ampoule snapper and hypodermic needle remover 10. At first a hypodermic syringe consist of the hypodermic syringe 57 and a hypodermic needle 56. The hypodermic needle 56 is inserted between the resilient blocks 24. The ampoule snapper and hypodermic needle remover 10 is closed by bringing the two arms 12,16 together and clamping the hypodermic needle 56 between the two resilient blocks 24. The ampoule snapper and hypodermic needle remover 10 can then be manipulated to remove the hypodermic needle 56 from the hypodermic syringe 57.
While a particular embodiment of the present invention has been described in the foregoing, it is to be understood that other embodiments are possible within the scope of the invention and are intended to be included herein. It will be clear to any person skilled in the art that modifications of and adjustments to this invention, not shown, are possible without departing from the spirit of the invention as demonstrated through the preferred embodiment. For example, while one particular type of block 24 has been described above, it is to be understood that this may be replaced with elements of different design to accommodate ampoules and vials of different sizes and configurations. The finger engaging portions 30 could be fitted with elements to improve the user's grip, such as a recess or ridges. The invention is therefore to be considered limited solely by the scope of the appended claims.
