Total Claims: 8
Claim 1
Independent Claim
110 words
A multi-needle syringe particularly for mesotherapeutical applications, comprising a plunger (5) having one end provided with an elastic seal (6) slidable inside a graduated barrel (1) with the end of which there is associated an offtake (2,2a,2b) having several outlet fittings, characterised in that said plunger (5) has a suction conduit extending over its entire length for introducing into said barrel (1) during the drawing step liquid substances to be mixed, there being provided at least one air-tight cap (4,3) engageable during said drawing step on said outlet fittings and during the ejection step of the mixtures on the end of said plunger (5) remote from said elastic seal (6).
Claim 2
Dependent Claim

A multi-needle syringe particularly for mesotherapeutical applications, comprising a plunger (5) having one end provided with an elastic seal (6) slidable inside a graduated barrel (1) with the end of which there is associated an offtake (2,2a,2b) having several outlet fittings, characterised in that said plunger (5) has a suction conduit extending over its entire length for introducing into said barrel (1) during the drawing step liquid substances to be mixed, there being provided at least one air-tight cap (4,3) engageable during said drawing step on said outlet fittings and during the ejection step of the mixtures on the end of said plunger (5) remote from said elastic seal (6).
Claim 3
Dependent Claim
29 words
A syringe according to Claim 1, characterised in that said plunger (5) has the end remote from said elastic seal (6) configured to accommodate an ordinary injection needle (10).
Claim 4
Dependent Claim

3 . A syringe according to Claim 1 or 2, characterised in that said plunger (5,8) has on its cylindrical surface a graduated scale for accurately metering said liquid substances to be mixed.
Claim 5
Dependent Claim
51 words
A syringe according to Claim 1, characterised in that it comprises at least one element (9a,9b) removably associable with the mouth of said barrel (1) and having in one portion thereof at least one elevation (9c) for self-centering on said mouth by reducing the guiding cross-sectional area of said plunger (5-8).
Claim 6
Dependent Claim

Claim 8
Dependent Claim
38 words
A syringe according to Claim 1, characterised in that said multi-needle offtake (7) has at least one siphon-like costrained passage for each of said outlet fittings to even out the amount of said mixture in said outlet fittings.
