- the end 7 of the syringe housing 3, is shown having a needle holding hub 2 retained therein, by engagement of the projections 8 thereof into recesses 9 in the syringe housing.
- the needle holding hub is shown having a hypodermic needle 10 attached thereto. Details of the needle holding hub will be described hereinafter with reference to Fig. 2.
- Fig. 1(b) illustrates the hypodermic needle syringe device when the plunger 4 has reached the end of the injection stroke, the end of the plunger 4 consequently abutting the end of the syringe housing 3.
- the release and lock mechanism 5 attached to the end of the plunger 4 has at this stage engaged the needle holding hub 2.
- the projections 11 at the end of the needle holding hub 2 have been biased towards each other by the inclined surfaces 12 on the release and lock mechanism 5, and have come to rest within the indentations 13 behind the inclined surfaces of the release and lock mechanism 5.
- a consequence of this forced movement is that the projections 8 of the needle holding hub have also been biased towards each other and out of the recesses 9 of the syringe housing, releasing the needle holding hub 2 from the syringe housing 3.
- Fig. 1(c) illustrates withdrawal of the plunger in the movement shown by arrow 14, the needle 10 being retracted to within the confines of the housing 3. During such movement, the needle holding hub 2 is locked into engagement with the release and lock mechanism 5 of the plunger 4.
- Fig. 2 illustrates a detailed view of the needle holding hub 2, Fig. 2(a) illustrating a cross-sectional view thereof, and Fig. 2(b) illustrating an end view thereof.
- Fig. 2 clearly shows the construction of the needle holding hub 2 in accordance with the preferred embodiment of the invention.
- the needle holding hub comprises a substantially cylindrical body section 15, with two arms 16 extending transversely therefrom at an angle inclined to the longitudinal axis of the cylindrical body portion 15.
- the overall outside appearance of the arms is of truncated conical shape with splits in opposed sides thereof.
- each arm is provided with a projection 8 extending outwardly therefrom, which forms the first engaging means which allows attachment of the needle holding hub 2 to the syringe housing 3, and a further projection 11 towards the ends of the arms 16 which enables connection of the needle holding hub to the release and lock mechanism 5 attached to the end of the plunger 4.
- the arms are preferably provided with inclined surfaces 17 thereon.
- Fig. 3 illustrates details of the syringe housing.
- Fig. 3(a) illustrating a cross-sectional view thereof.
- Fig. 3(b) illustrating an end view thereof, and
- Fig. 3(c) detailing an enlarged view of the end 18 of the housing 3.
- the end 18 of the syringe housing is correspondingly shaped to receive the needle holding hub 2 therein, and provides inner surfaces, the extremity of which is cylindrical in shape and shown by numeral 19, and the intermediate portion 20 of which is of truncated conical shape.
- the end 18 of the syringe housing 3 is also shown having recesses 21 which are adapted to engage the projections 8 of the needle holding hub 2.
- the end face 22 is also shown having a domed shaped portion in the centre thereof, for the specific purpose of misaligning the needle should an attempt be made to reinsert the needle through the needle receiving hole 23, after an initial use of the syringe device 1.
- Fig. 4 illustrates the plunger portion of the invention, Fig. 4(a) illustrating a cross-section view thereof, Fig. 4(b) illustrating an end view thereof, and Fig. 4(c) detailing an enlarged view of the end portion 24 of the plunger 4.
- the end portion 24 is shown having a substantially concavely shaped recess 25 provided with indentations 26 spaced from the inclined entry surfaces 27 thereof.
- the purpose of the inclined entry surfaces 27 is to bias the arms 16 of the needle holding hub 2 towards each other (as shown in Fig.
- a central conically truncated shaped portion 28 is provided axially in the centre of the concavely shaped portion 25, to facilitate alignment and engagement of the needle holding hub 2 within the release and lock mechanism 5. It will however be appreciated that this central portion 28 is not an essential portion for operation of the invention.
- a hinging tab 34 which may be optionally supplied on the plunger 4 to prevent accidental premature engagement of the plunger 4 with the needle holding hub 2. Obviously, at the intended time of use, the tab 34 is removed.
- Fig. 5 illustrates a seal 29 which may be utilised in conjunction with the present invention. The seal is adapted to be provided about the plunger 4 such that an airtight seal is provided between the plunger 4 and the syringe housing 3. Various other forms of similar or known prior art seals may be provided about the various components of the device, as required.
- Fig. 6 illustrates examples of where two sealing means may be provided on the inner surface of the syringe housing 3.
- the seal indicated by numeral 30 is shown as a circular rib provided on the inside of the cylindrical bore, providing a slight interference fit with the cylindrical body portion of the needle holding hub 15 to provide an airtight seal.
- the seal indicated by numeral 31 shows a short taper on top of the cylindrical section of the needle holding hub 2 which seals against a sharp corner on the inside of the corresponding p .ition in the syringe housing 3. This also gives an airti,_.t seal between the hub 2 and the syrin e housing 3.
- Fig. 7 illustrates an alternatively preferred embodiment of the hub described hereinbefore.
- the hub 2 is provided with two differently shaped arms 32 and 33 thereon, which are obviously adapted to engage correspondingly shaped portions of the plunger 4. This ensures that the needle is retracted to an off-centre position, consequently ensuring that the needle 10 cannot be accidentally inserted within the hole 23 of the syringe housing 3 for a second withdrawal and injection stroke.
- Other methods of embodying the device to ensure that the needle is displaced off-centre will become obvious to persons skilled in the art.
- the needle channel 23 could be constructed to be offset from the axis, to achieve the same result.
- Fig. 8 is illustrated an alternative embodiment of the hypodermic needle syringe device which has a self-retracting means and a self-cleansing means incorporated therein.
- Fig. 8(a) illustrates the device 1 prior to activation of the injection stroke, wherein a sterilising solution is contained within a housing 35 having a repturable membrane 36 along one face thereof.
- the housing 35 is positioned adjacent the needle hub 2.
- the membrane 36 is automatically ruptured by automatic retraction of the needle 10 by a spring 36 into the housing 35, as shown in Fig. 8(c). Therefore, the device illustrated in Fig.
- a resilient material is preferably utilised to construct the needle holding hub, or at least the arms thereof. It will however also be appreciated that whilst this may be one preferred implementation, this component could be rigid in construction and the engaging plunger end and housing end could be provided of resilient material. It will also be appreciated that whilst the needle holding hub has been herein described as having projections which, are adapted to engage correspondingly shaped recesses in the engaging components of the syringe, recesses could alternatively be provided on the needle holding hub which engage projections on the other device components. The size and shape of such engaging means are also obviously variable.
