Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
169 words
A needle for medical use, provided with a protective cap (2) substantially cylindrical in shape, with one open end (9) and an opposite opening (10), the diameter of the cap (2) being such that it can slide on a cylindrical body provided at the back of the needle to move from a needle covering position to a position in which the needle is uncovered and vice versa, wherein said cylindrical body (7, 7', 7", 7"') is integral with the needle (1) and inside the cap (2), near the open end (9) a seating (14) is provided, suitable for receiving a substantially oval widened base or collar (4) of the needle (1), the seating (14) being limited at the top by a continuous or broken annular projection (12) forming an insurmontable ledge for the base of the needle, and at the bottom by two opposed "half-moon" projections (13), shaped in such a way as to allow the base ( 4 ) of the needle (1) to pass, after correct positioning.
Claim 2
Dependent Claim
169 words
A needle for medical use, provided with a protective cap (2) substantially cylindrical in shape, with one open end (9) and an opposite opening (10), the diameter of the cap (2) being such that it can slide on a cylindrical body provided at the back of the needle to move from a needle covering position to a position in which the needle is uncovered and vice versa, wherein said cylindrical body (7, 7', 7", 7"') is integral with the needle (1) and inside the cap (2), near the open end (9) a seating (14) is provided, suitable for receiving a substantially oval widened base or collar (4) of the needle (1), the seating (14) being limited at the top by a continuous or broken annular projection (12) forming an insurmontable ledge for the base of the needle, and at the bottom by two opposed "half-moon" projections (13), shaped in such a way as to allow the base ( 4 ) of the needle (1) to pass, after correct positioning.
Claim 3
Dependent Claim
39 words
A needle according to claim 1, wherein inside the said seating (14) at least one tooth (6) is provided, acting as a stop for the rotation of the cap (2) with respect to the base (4) or vice versa.
Claim 4
Dependent Claim
46 words
A needle according to claim 1, wherein on the base (4) of the needle (1) at least one notch (8) is provided, suitable for engaging with a corresponding longitudinal guide (15) provided inside the cap (2) for a guided sliding between the needle and the cap.
Claim 5
Dependent Claim
50 words
A needle according to claim 1 wherein at least the projection (12) or the projections (13), or both, have dimensions such that they interfere slightly with the outer surface of the cylindrical body (7, 7', 7", 7"'), so as to make the cap (2) integral with the cylindrical during use.
Claim 6
Dependent Claim
22 words
A needle according to claim 1 wherein the said opening (10) is made centrally at a tapered end of the cap (2).
Claim 7
Dependent Claim
40 words
A needle according to claim 1 wherein said cylindrical body is a tubular support (7) at the back of the base (4) and integral with the needle (1) for connection to a tang (6) of a syringe (7bis) (FIGS. 1-12).
Claim 8
Dependent Claim
33 words
A needle according to claim 1 wherein said cylindrical body is a sleeve (7') integral with the needle (1) and encloses a second needle (1') disposed axially with the needle (1) (FIG. 13).
Claim 9
Dependent Claim
55 words
A needle according to claim 1 wherein said needle (1) is the guide needle or mandrel of a cannula needle, and wherein said cylindrical body is a handle (7") of the guide needle (1) and the cap (2) is located between said handle (7") and a tubular body (21) of the cannula (20) (FIGS. 14-20).
Claim 10
Dependent Claim
18 words
A cannula-needle according to claim 8, wherein two flexible wings (22) are provided outside said tubular body (21).
Claim 11
Dependent Claim

Claim 12
Dependent Claim
36 words
A butterfly needle according to claim 10, wherein pairs of opposed wings (34, 35) forming seats (36) are provided on said cap (2) to house and make the wings (30) of the butterfly needle (1) slide.
