In Australia April 21, 1947 i 7 .3Claims. (01. 128-218) This invention relates to an improved device for injecting penicillin-or similarliquids. It is well known that penicillin in oi1,'or similar relatively viscous liquids, are difficult to inject through the ordinary medicinal syringe for the reason that the liquid cannot beg readily drawn into the syringe and in some cases must be heated to enable filling of the syringe. e
Heating is undesirable in the case of penicillin which deteriorates under these conditions and according to an earlier invention of mine it has been proposed to store and distribute the penicillin or the like inrcontainerszwhich are'provided at one gend with means whereby they can be engaged on the buttrend of thelsyringe when the needle is removed therefrom and a plunger then actuated at the other end to positively force the contents of the container into the syringe, it being possible in this way to handle relatively thick or viscous liquids in that displacement from the container is by positive pressure and not by suction.
This method still makes it necessary to use the ordinary syringe which must be sterilised and dried before use and cleaned after use, and it is therefore the object of this invention to provide means whereby injection can take place directly from the improved container without first having to transfer from the container to the standard syringe.
In order however that the invention may be more clearly understood, it will now be described with reference to the accompanying drawings in which:
Fig. 1 is a perspective view of a device according to this invention, and
Fig. 2 is a central longitudinal section of the device showing a container and needle in place as when efiecting an injection.
A hollow body I formed by bending a strip of metal has at its one end a cap 2 which serves to take a double ended hollow connector 3 tapering outwardly from a screw threaded central section 4 which engages in the cap 2.
The hollow body I is of a sufficient size to take the container 5 of penicillin or the like, the body being tapered at the cap end to engage a resilient closure 6 disposed on the discharge end of the container 5, the inner face of'the cap 2 engaging this resilient closure to lock the container in position and effect the required seal.
The part 8 of the connector 3 is adapted, when the container 5 is placed into position, to be forced into an aperture 9 in the resilient closure 6 of the container, part IU of the connector 3 be- 2 ing adapted to take a needle H. Different size connectors can be provided to fit different needles or different containers.
Disposed through an aperture at the other end of the hollow body I in which the container 5 is held is a stem l4 carrying a piston l5 at its one end which is adapted to fit into the container 5 to actuate a wad or piston l6 disposed within such container, the lengthyof the-'stem1l4 beingsuch that when pressure is applied .to its external end,- which is provided with a flange or pressmeans H, the wad 16 within the container 5 is pushed forward to cause the penicillin or the like to be forced out of. the containerv 5 through the hollow connector 3 and thus into and through the needle I I; the stem l4 being stopped when the wad l5 within the container 5 reaches the end of such container.
Finger grips I 8 are provided on the rear end of the hollow body I in a manner somewhat similar to a syringe.
To allow the containers 5 to be positioned or removed, the hollow body I is provided with means whereby the body may be sprung outwardly, such means comprising an end 20 having through it an aperture "2| in which is engaged a tongue 22 projecting from the other end 23. This arrangement allows the body I to be opened out by distorting the metal of the body I to cause the tongue 22 to be disengaged from the aperture 2|. To prevent the body from collapsing inwardly too far when pressure is applied to the finger grips l8 during an injection, a tongue 25 is provided which projects down into the path of the end 20 of the body.
The described device can oi. course be materially varied in its construction but the underlying principle consists in providing a body I in which a container 5 of penicillin or the like can be held and which incorporates means whereby a connector 3 is projected into an aperture '9 through the closure 6 at the end of the container 5, pressure means such as the stem [4 and piston [5 allowing the penicillin or the like to be forced out of the container '5 through the connector 3 and into and through the needle II.
In this way a device is provided which can be used to effect the actual injection of the content of the container, the penicillin or the like requiring no transfer from its initial container to any other container and thereby greatly enhancing the hygienic aspects while at the same time removing the need of cleaning and sterilising a syringe. The operation of filling the usual syringe is also entirely removed. The connector 3 is made detachable so that this can be sterilised,
it being possible to carry this in a small sterile container and to position same just before use, thus obviating the need of complete sterilisation of the unit. The connector 3 can be taken from the sterile container byengaginggthe needle H on the connector 3 .andthen screwing the'c'onnector into the cap 2, thus avoiding direc handling of the sterile connector. 1
Another advantage is that thecontainer of penicillin or the like can still be used With the normal syringe if such is thought desirable or necessary. i
