Abstract
Abstract A front element (10) is provided close to the front portion (31) of the needle (3), said element (10) being foldable on itself substantially about a first folding axis (A) parallel to the front portion (31); means (21, 22, 13, 16) are also provided to constrain the rear portion (32) of the needle to the front element (10) such that the needle (3) can rotate with respect to the element (10) substantially about a second folding axis (B) substantially perpendicular to the needle (3). The device (1) can assume a first operating configuration in which the element (10) is folded on itself by rotation along the first axis (A), with the front portion (31) enclosed between the two fins (10') of the element (10), these facing each other in mutual contact; the device (1) can also assume a second operating configuration, by rotating the element (10) with respect to the needle (3) along said second axis (B), in which the front portion (31) freely projects from the element (10).

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
224 words
A needle holding device for penetration into the body, such as a needle for intravenous infusion, dialysis and similar uses, characterised by comprising: - a front element (10) positioned adjacent but not constrained to the front portion (31) of the needle (3), said front element (10) being foldable on itself substantially about a first folding axis (A) parallel to the front portion (31) of the needle; - means (21, 22, 13, 16) which constrain the rear portion (32) of the needle to the front element (10) such that the needle (3) can rotate with respect to the front element (10) substantially about a second folding axis (B) substantially perpendicular to the needle (3); - the device (1) being able to assume a first operating configuration in which the front element (10) is folded on itself by rotation along said first axis (A), with the front portion of the needle (3) enclosed between the two fins (10') of the element (10), these facing each other in mutual contact, the point of the needle (3) not projecting from the element (10); - the device (1) being able to assume a second operating configuration, by rotating the front element (10) with respect to the needle (3) along said second axis (B), in which the front portion (31) of the needle freely projects from the front element (10).
Claim 2
Dependent Claim
31 words
A device as claimed in claim 1, characterised in that when in said second operating configuration, said front element (10) can be folded on itself about said first folding axis (A).
Claim 3
Dependent Claim
68 words
A device as claimed in claim 2, characterised in that said constraining means (21, 22, 13, 16) comprise a bush (21) which surrounds the rear portion (32) of the needle (3) and is rigidly fixed to this portion and to one or more flexile portions (13, 16) which connect it the front portion (10), said flexible portions (13, 16) enabling said rotation about said second folding axis (B).
Claim 4
Dependent Claim
55 words
A device as claimed in claim 2, characterised in that said front element (10) is formed from a thin plate sufficiently rigid to the extent that during normal needle use it cannot undergo deformation such as to enable the point of the needle (3) to project beyond the element (10) when in its first configuration.
Claim 5
Dependent Claim
42 words
A device as claimed in claim 4, characterised in that said front element (10) comprises a folding region (12) enabling rotation about said first axis (A), the front portion (31) of the needle (3) being positioned adjacent to said folding region (12).
Claim 6
Dependent Claim
67 words
A device as claimed in claim 3, characterised by comprising a rear element (22) in the form of a thin plate, joined to the bush (21) in a manner coplanar therewith and joined by said flexible portions (13) to the front element (10) in a manner substantially coplanar therewith, said rear element (22) being foldable on itself about an axis substantially coinciding with the first axis (A).
Claim 7
Dependent Claim
45 words
A device as claimed in claim 6, characterised in that when in said second configuration, the front element (10) faces and is in contact with the rear element (22), said elements (10, 22) being able to be further folded together about said first axis (A).
Claim 8
Dependent Claim
53 words
A device as claimed in claim 3, characterised by comprising a short, flat, flexible thin strip (16) which joins the front edge of the bush (21) to the rear edge of the front element (10), said strip (16) being positioned substantially coaxial to said first axis (A) and defining said flexible portion (13).
Claim 9
Dependent Claim
79 words
A device as claimed in claim 3, characterised by comprising a member (17) joined to the front element (10) and having a channel (17') extending parallel to said first axis (A), said channel (17') projecting outwards from that face of the front element (10) opposite the face which encloses the front portion (31) of the needle when in the first operating configuration, said bush (21) being arranged to snap-penetrate into the channel (17') when in the second operating configuration.
Claim 10
Dependent Claim
39 words
A device as claimed in claim 1, characterised by comprising means (41, 42, 45, 46) for disengagably constraining one to the other the two mutually facing fins (10') of the front element (10) when in its first operating configuration.
Claim 11
Dependent Claim
54 words
A device as claimed in claim 10, characterised in that said constraining means (41, 42, 45, 46) comprise one or more projections (41, 45) provided on relative fins (10') and able to be press-inserted into corresponding cavities (42, 46) provided in the opposing fin (10'), so as to form a constraint of "snap-fastener" type.
Claim 12
Dependent Claim
37 words
A device as claimed in claim 7, characterised by comprising constraining means (42, 43) for disengagably constraining one to the other the mutually facing front element (10) and rear element (22) when in said second operating configuration.
Claim 13
Independent Claim
117 words
A device as claimed in claims 5 and 10, characterised in that said front element (10) comprises a further folding region (15) defining a folding axis (C) parallel to but spaced from the first axis (A), said further folding region (15) defining in a first fin (10') an end portion (10'a) and an intermediate portion (10'b), said front element (10) being folded, when in the first operating configuration, such that the second fin (10') is in contact with the intermediate portion (10'b) of the first fin (10') and the end portion (10'a) is in contact with the second fin (10'), said constraining means (45, 46) being positioned between the end portion (10'a) and the second fin (10').
Claim 14
Dependent Claim
21 words
A device as claimed in claim 1, characterised by being constructed in one piece from synthetic resin by a moulding process.
