Abstract
Abstract The invention provides an assembly of a needle shield (6) for a needle channel (10) and a self-sealing diaphragm (5), wherein the needle shield (6) is generally cup-shaped and is provided with an aperture (8), said self-sealing diaphragm (5) being retained in the aperture (8), the arrangement being such as to protect the fingers of the operative from needle-stick by the miss-direction of a hypodermic needle. The diameter of the aperture (8) may approximate to, or be smaller than, the internal diameter of the inlet of the needle channel (10) so that not only is needle-stick obviated, but also the tendency of the needle point to tear the seal-sealing diaphragm (5) is significantly reduced.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
117 words
A protective shield assembly for a needle channel comprising a protective shield and a self-sealing diaphragm, wherein the protective shield is generally cup-shaped and is adapted to extend generally radially of the diaphragm to protect the fingers from needle stick, and is provided with an aperture, said self-sealing diaphragm being retained in use in the aperture; wherein the diameter of the aperture approximates to or is smaller than, the internal diameter of the inlet of the needle channel with which it is adapted to be used; and wherein the protective shield is formed of a malleable, non-resilient material to allow the shield to be manually formed to and retained in a shape configured to a body surface.
Claim 2
Dependent Claim
117 words
A protective shield assembly for a needle channel comprising a protective shield and a self-sealing diaphragm, wherein the protective shield is generally cup-shaped and is adapted to extend generally radially of the diaphragm to protect the fingers from needle stick, and is provided with an aperture, said self-sealing diaphragm being retained in use in the aperture; wherein the diameter of the aperture approximates to or is smaller than, the internal diameter of the inlet of the needle channel with which it is adapted to be used; and wherein the protective shield is formed of a malleable, non-resilient material to allow the shield to be manually formed to and retained in a shape configured to a body surface.
Claim 3
Dependent Claim
44 words
An assembly according to claim 1 characterised in that the diaphragm is externally disposed about the needle channel and in that the protective shield is provided with a convergent tubular portion adapted to be a push-fit over the external diaphragm and the needle channel.
Claim 4
Dependent Claim
20 words
An assembly according to claim 2 characterised in that the diaphragm is substantially contiguous with the curve of the shield.
Claim 5
Dependent Claim
31 words
An assembly according to claim 1 characterised in that the diaphragm is internally retained at the entrance to the needle channel by a portion of the protective shield adjacent the aperture.
Claim 6
Dependent Claim
22 words
An assembly according to claim 1 characterised in that the protective shield is provided at its outermost rim with an inturned rib.
Claim 7
Dependent Claim
124 words
A protective shield assembly for a needle channel comprising a protective shield and a self-sealing diaphragm, wherein the protective shield is generally cup-shaped and is adapted to extend generally radially of the diaphragm to protect the fingers from needle stick, and is provided with an aperture, said self-sealing diaphragm being retained in use in the aperture; wherein the diameter of the aperture approximates to or is smaller than, the internal diameter of the inlet of the needle channel with which it is adapted to be used, and wherein the diaphragm is externally disposed about the needle channel and the protective shield is provided with a tubular portion adapted to be a resilient push fit over the external diaphragm when positioned about the needle channel.
Claim 8
Dependent Claim
124 words
A protective shield assembly for a needle channel comprising a protective shield and a self-sealing diaphragm, wherein the protective shield is generally cup-shaped and is adapted to extend generally radially of the diaphragm to protect the fingers from needle stick, and is provided with an aperture, said self-sealing diaphragm being retained in use in the aperture; wherein the diameter of the aperture approximates to or is smaller than, the internal diameter of the inlet of the needle channel with which it is adapted to be used, and wherein the diaphragm is externally disposed about the needle channel and the protective shield is provided with a tubular portion adapted to be a resilient push fit over the external diaphragm when positioned about the needle channel.
Claim 9
Dependent Claim
18 words
An assembly according to claim 6 characterised in that the protective shield is formed of a malleable material.
Claim 10
Dependent Claim
31 words
An assembly according to claim 6 characterized in that the diaphragm is internally retained at the entrance to the needle channel by a portion of the protective shield adjacent the aperture.
Claim 11
Dependent Claim
20 words
An assembly according to claim 6 characterized in that the diaphragm is substantially contiguous with the curve of the shield.
Claim 12
Dependent Claim
22 words
An assembly according to claim 6 characterized in that the protective shield is provided at its outermost rim with an inturned rib.
