Abstract
A syringe head for attachment to a syringe, the head comprising a needle (3), a needle holder (1) through which the needle passes, and a shroud (4) attached to the needle holder, and moveable between an extended position in which the needle is covered by the shroud, and a retracted position in which the needle is exposed.
Description
NEEDLE WITH SHROUD
The present invention relates to syringes.
A typical syringe comprises a body for holding a medicament which communicates with a needle. In order to protect the needle and prevent accidental pricking, a shroud may be telescopically attached to the syringe body. When the shroud is in an extended position it covers the needle thereby reducing the risk of accidental pricking. When the needle is to be used, the user presses the shroud against his or her skin causing the shroud to be pushed back to a retracted position and allowing the needle to penetrate the skin.
Needles are generally disposable and reuse is to be avoided. However, cost constraints dictate that syringes should, if possible, be reusable.
According to a first aspect of the present invention, there is provided a syringe head for attachment to a syringe, the head comprising: a needle; a needle holder through which the needle passes; and a shroud attached to the needle holder, and moveable between an extended position in which the needle is covered by the shroud, and a retracted position.
It is preferred that the syringe head comprises attachment means for attaching the syringe head to a syringe, the attachment means selected from any of: a screw thread; a bayonet fitting; a snap fitting; and a friction coupling.
Preferably, the syringe head further comprises a releasable lock configured to hold the shroud in the extended position. The releasable lock may be selected from:
• co-operating screw threads formed on the shroud and the needle holder;
• mechanically interlocking clips formed respectively on the shroud and the needle holder; and
• a lug disposed on the needle holder, the lug configured to snap fit into an opening disposed on the shroud.
Biasing means may be disposed between the needle holder and the shroud, the biasing means arranged to urge the shroud towards the extended position. It is preferred that the biasing means is selected from a compressible material and a helical spring.
Preferably, the syringe head further comprises locking means configured to releasably lock the shroud in the retracted position.
There is also provided a syringe comprising the syringe head described above.
For a better understanding of the present invention and in order to show how the same may be carried into effect reference will now be made by way of example to the accompanying drawings in which:
Figure 1 illustrates various views of a syringe head according to a first embodiment;
Figure 2 illustrates various views of a syringe head according to a second embodiment;
Figure 3 illustrates various views of a syringe head according to a third embodiment;
Figure 4 illustrates various views of a syringe head according to a fourth embodiment; and
Figure 5 illustrates various view of a syringe head according to a fifth embodiment.
A syringe "head" suitable for attachment to a syringe body will now be described. Referring to Figure 1 , the syringe head 1 comprises a needle holder 2, a needle 3 embedded in and extending through the needle holder 2, a shroud 4 attached to the needle holder 2 and moveable linearly relative to the needle holder 2, and a helical spring 5 disposed between the needle holder 2 and the shroud 4.
The needle holder 2 comprises a screw thread 6 to releasably attach the needle holder 2 to a corresponding screw thread on the body of a syringe (not shown). However, other suitable means may be used for attaching the needle holder to the body of a syringe, including a bayonet fitting, a snap fitting or a friction coupling. The needle 3 comprises a first tip 7 for penetrating skin and a second tip at the opposite end the needle 3. The needle 3 extends through the needle holder 2 such that, when the needle holder 2 is attached to a syringe body, the second tip of the needle 3 extends into the body and can therefore pass medicaments stored in the body, or in a cartridge in the body, from the rearward end of the needle 3 to the first tip 7. The first tip 7 extends away from the needle holder 2 such that when in use, it can penetrate skin.
The shroud 4 comprises an opening 8 through which the first tip 7 of the needle 3 can pass. The shroud 4 is moveable relative to the needle holder 2 such that when the shroud 4 is in an extended position the first tip 7 of the needle 3 is covered by the shroud 4, and as the shroud 4 is moved back into a retracted position, against the biasing action of the spring, the first tip 7 of the needle passes through the opening 8 and is exposed.
When a user desires to use the syringe, the user presses the syringe head against the skin, causing the shroud to be pushed back to its retracted position, allowing the first tip 7 of the needle 3 to penetrate the skin.
When the user removes the syringe head, the spring 5 urges the shroud 4 towards the extended position, such that the shroud 4 covers the first tip 7 of the needle 3.
The shroud 4 and the needle holder 2 comprise locking means to lock the shroud 4 in the extended position, thereby protecting the first tip 7 of the needle. The locking means comprises a co-operating screw thread 9, 11 disposed on the shroud 4 and the needle holder 2 respectively.
After use, the entire syringe head may be disposed of and replaced by a new syringe head. As the shroud is urged by the spring towards its extended position, there is very little risk of the used needle accidentally pricking a person once the syringe head has been disposed of.
According to a second embodiment, and referring to Figure 2, the screw threads 9, 10, 11 of Figure 1 are replaced by interlocking projections 12, 13, 14 disposed on the needle holder 2 and the shroud 4. These projections have sufficient force to hold the shroud 4 in the extended position. A user can easily release the interlocking projections, thereby allowing the shroud to move relative to the needle holder during normal use. The second specific embodiment is otherwise compatible with the first specific embodiment.
According to a third embodiment, and referring to Figure 3, the screw threads 9, 10 of Figure 1 that lock the shroud 4 in the extended position are replaced by a co-operating snap fit lug disposed on an outer surface of the needle holder 2 that snaps into a corresponding opening 16 on the shroud. The third specific embodiment is otherwise compatible with the first specific embodiment.
According to a fourth embodiment, and referring to Figure 4, the shroud 4 comprises an L-shaped opening 17, and the needle holder 2 comprises a projecting lug 18 configured to co-operate with the opening 17. When the shroud is in the extended position, the lug 18 snaps into one of the arms of the L shaped opening, thereby maintaining the shroud 4 in the extended position. The fourth specific embodiment is otherwise compatible with the first specific embodiment.
According to a fifth embodiment, and referring to Figure 5, the helical spring 5 or the previous embodiments is replaced by linear biasing means 19. The fifth specific embodiment is otherwise compatible with any one of the first to fourth embodiments.
It will be appreciated by those of skill in the art that various modifications may be made to the above described embodiments without departing from the scope of the present invention.
