Description
INJECTION DEVICE
This invention relates to injection devices, and in particular to devices for giving injections of an anaesthetic or other drug to humans preparatory to or during dental, surgical or other medical treatment.
For such purposes it is cu-stomary to provide a disposable hypodermic needle which is secured to a syringe device for use and is then detached from the syringe device and discarded. A container in which the needle is supplied, and its cap, are also disposable, the needle being returned into the container and the cap being replaced on the container prior to such disposal. By this means it is intended to ensure that a patient is not contaminated due to the use of an other than unused needle. Such a needle has a body secured thereto by means of which the needle may be handled and attached to the syringe, the needle protruding from the body at opposed ends thereof.The distal end of the needle is, in use, inserted into the patient, whilst the proximal end is inserted into the syringe device to penetrate a container of anaesthetic or other drug contained in the syringe device. During attachment of a needle to the syringe device, or removal therefrom, it is possible that the proximal end of the needle can come into contact with the end of the syringe device. In consequence, unless the syringe device is sterilised after each use, there is a possibility that a new and unused needle can become contaminated on attachment to the syringe device by deposits left thereon during withdrawal therefrom of a previously used needle.
It is an object of the present invention to provide an injection device the use of which precludes, or substantially reduces the risk of the aforementioned possibility.
The invention provides an injection device comprising a needle and a syringe device, said needle having a body secured thereon and said syringe device comprising a housing adapted to receive # container therein, said body being adapted to be attached to said housing, wherein said device is provided with cooperating formations adapted to permit said attachment but to resist separation thereof.
Embodiments of injection device in accordance with the invention will now be described with reference to the accompanying drawings in which:
Fig. 1 is an exploded view, partly in section, of a
first embodiment;
Fig. 2 is an exploded view, partly in section, of a
second embodiment:
Fig. 3 is an exploded view, partly in section, of a
third embodiment;
Fig. 4 is a sectional elevation, to an enlarged scale,
of part of the injection devices of any one of
Figs. 1 to 3;
Fig. 5 is a sectional elevation of a fourth embodiment
and,
Fig. 6 is a section on line Ul-Vl of Fig. 5 to an
enlarged scale.
Referring now to Fig.l there is shown an injection device 10 comprising a needle 11 and a syringe device 12.
The needle 11 is provided in a container 13 having a cap 14 so as to be fully protected before it is required for use.
The needle 11 has a body 15 secured thereon, for example, a body of plastics material moulded thereon. The body 15 is a push fit in the container 13, which is long enough to receive the distal end 16 of the needle 11 therein. The cap 14 is a push fit on the body 15 and container 13 and has a bore 17 therein to receive the proximal end 18 of the needle 11 therein. The syringe device 12 has a body part 19 with a finger grip 20, a plunger 21 and a housing 22. The housing 22 comprises a hollow cylinder in which a container (not shown) of an anaesthetic or other drug can be placed. The housing 22 is pivotally attached at 23 to the body part 19 so that it can be pivoted out of axial alignment therewith for loading of the drug container when the plunger 21 is fully retracted.To the end of the housing 22 remote from the body part 19 is screwed a housing cap 24 having an end part 25 of reduced diameter to which the body 15 of the needle 11 can be attached. Conventionally the syringe device 12, comprising the body part 19, plunger 21, housing 22 and housing cap 24, is of stainless steel so as to resist corrosion and to be resistant to all of the substances with which it is likely to come into contact in normal use.
However with the conventional arrangement it can be seen that during attachment of the body 15 to the housing cap 24 or removal therefrom normally by means of screwing the former onto or from the latter, it is possible for the proximal end 18 of the needle 11 to come into contact with the housing cap 24. In consequence contamination of a new and unused needle can occur unless the syringe device 12, or at least the housing cap 24, is sterilised between each use of the syringe device 12. To prevent, or at least subtantially reduce the risk of such contamination, the body 15 of the needle 11 and the housing cap 24 are provided with cooperating formations which permit their attachment but prevent or resist their separation, as is described hereinafter.For such a purpose the housing cap 24 is also moulded of a plastics material so that it may be discarded with the needle 11, container 13 and cap 14 after use. In order that the proximal end 18 of the needle 11 is fully protected during such disposal the cap 14 is provided with a second bore 26 to receive the proximal end 18 when the cap 14 is inserted into the housing cap 24. The distal end 16 of the needle 11 is of course replaced in the container 13 for disposal.
Referring now to Fig.2 there is shown an injection device 27 which is similar in most respects with the device 10 described above, and corresponding parts are identified by corresponding numerals. However, in this case the housing 22 is screwed into the body part 19 of the syringe device 12.
In addition the housing 22 is moulded of a plastics material and has a reduced end part 25, to which the body 15 of the needle 11 may be readily attached but not removed. In this case the housing 22 is discarded with the needle 11, container 13 and cap 14. Because the housing 22 is considerably longer than the proximal end 18 of the needle 11, the proximal end 18 is adequately protected during disposal.
Referring now to Fig. 3 there is shown an injection device 28 which is generally similar to the device 27 described above. However in this case the housing 22 is screwed into a "gun-type" plunger operating syringe device 12. With such a device manipulation of the trigger 29 causes progressive movement of the plunger 21 to force the contents of the drug container (not shown) in the housing 22 along the needle 11. In the embodiment shown in Fig.3 the housing 22 is disposable as described in relation to the fig. 2 embodiment. However, a non-disposable housing 22 of stainless steel, having a disposable housing cap 24 of plastics material attached thereto, can be used with the syringe device 12 if preferred, as described in relation to the fig. 1 embodiment.
In each of the above described embodiments the body 15 and the reduced end part 25 of the housing cap 24 or housing 22 have cooperating formations thereon which permit their attachment and prevent or resist their separation. One embodiment of such formations is shown in Fig.4. In this embodiment the body 15 of the needle 11 has a bore 30 provided with at least one and preferably a plurality of annular saw-tooth formations 31 therein, The reduced diameter end part 25 of the housing cap 24 or housing 22 is also provided with at least one and preferably a corresponding plurality of like annular saw-tooth formations 32 thereon. By this means the end part 25 may be readily inserted in the bore 30 of the body 15, but may not be readily removed therefrom.
A second embodiment of such formations is shown in
Figs. 5 and 6. In this case an injection device 33 is shown, which is generally similar to that shown in Fig. 2 and corresponding parts are identified by corresponding reference numerals. In this case the cap 24, to which the body 15 of the needle 11 is attached, is secured in the end of the housing 22. As shown more clearly in Fig. 6 the cap 24, which is preferably of a plastics material, is provided with at least one and preferably a plurality of outwardly extending flexible arms 34, four being shown in this embodiment, but any number of arms 34 may be provided.
A similar number of ratchet teeth 35 are provided around inner surface of the housing 22. In consequence the housing cap 24 can rotate relative to the housing 22 about a longitudinal axis thereof as shown by the arrow A but is prevented from such relative rotation in the opposite direction by abutment of the arms 34 against the ratchet teeth 35. By this means the body 15 of needle 11 can be readily screwed onto the housing cap 24 whilst holding the housing 22 since rotation of the housing cap 24 relative to the housing 22 in the direction of screwing of the body 15 on the cap 24 is prevented. However the body 15 cannot readily be unscrewed from the housing cap 24 when the housing 22 is held since the housing cap 24 can freely rotate in the unscrewing direction relative to the housing 22.In consequence, removal of the housing 22 from the body part 19 of the syringe device 33, preferably by unscrewing one relative to the other, is more readily accomplished. In this embodiment, as with that of Fig. 2, the housing 22 is also preferably of a plastics material so that it may be discarded with the needle 11, container 13 and cap 14, after use. As an alternative, the arms 34 may be provided on the housing 22 and the ratchet teeth 35 on the cap 24.
In each of the embodiments of housing 22 shown in
Figs. 1 to 6, a cartridge 36 containing the requisite anaesthetic or other drug is inserted. Conventionally such cartridges are of glass and have a bung or stopper 37 at each end. One bung or stopper 37 is contacted by the plunger 21 of the syringe cartridge 36 and serves as a piston in the glass whilst the other bung or stopper has a metal rim with a rubber seal insert which is pierced by the proximal end 18 of a needle. Such cartridges can be autoclaved for further use, which is a time consuming operation, or are discarded, which is costly.
To overcome this problem a cartridge for use with any of the syringe devices shown in Figs. 1 to 3 may be a tube of a rigid plastics material having a piston type bung at one end and a thin membrane at the other end which is readily pierced by the proximal end 18 of a needle 11. As an alternative the plastics material may be flexible and the cartridge 36 be compressed under the action of the plunger 21. After use the relatively cheap cartridge 36 may be discarded with the needle 11 and the housing 22. As a further alternative, as shown in Fig. 5 the housing 22 of the Fig. 2 or Fig. 5 embodiments may be of rigid plastics material having a piston type bung 37 at one end of a bore 36 thereof and a thin membrane 38 at the other end which is readily pierced by the proximal end 18 of a needle 11 as the latter is screwed onto the housing cap 24.In this case the anaesthetic or other drug is contained in the housing 22 and not in a separate cartridge.
A further problem associated with conventional syringe devices, particularly of the types shown in Figs. 1, 2 and 5, is that when the plunger 21 is fully extended, the end of the plunger 21 may be spaced too far from the finger grip 20 for small handed people to operate the syringe device properly and conveniently. To overcome this problem the finger grip 20 may be positionally adjustable on the body 19 in the direction of sliding movement of the plunger 21 relative to the body 19, as shown in Fig. 2, but is equally applicable to the embodiments of Figs. 1 and 5. In this case, as shown in
Fig. 2, the body 19 has a screw threaded portion 39 along which finger guard 20 can be slid or screwed and locked in the desired position by means of respectively two or one screwthreaded locking rings 40. Other forms of adjustment may be provided if desired, for example locating pins and a plurality of apertures spaced along the body 19, or a transverse locking screw in finger guard 20.
By means of the invention it is ensured that, together with each used needle, all of the parts of the injection device which are likely to be contacted in use by a needle are discarded after each use of the syringe device so that contamination of new unused needles is prevented, or the risk thereof is substantially reduced.
