Abstract
A device for dispensing viscoelastic solutions, said device consisting of a syringe (1) which contains at least two viscoelastic solutions (V1, V2) having different properties, said solutions (V1, V2) being dispensed in succession, in a predetermined order, said device being characterized in that said syringe (1) includes at least one moving diaphragm (10) that separates said at least two viscoelastic solutions (V1, V2).
Claims20
A device for dispensing viscoelastic solutions, said device consisting of a syringe (1) formed with a single body which contains at least two viscoelastic solutions (V1, V2) having different properties, said solutions (V1, V2) being dispensed in succession, in a predetermined order, said viscoelastic solutions being separated by a single moving diaphragm only incorporating a small opening (11) enabling the viscoelastic solution (V2) disposed upstream from the diaphragm (10) to be discharged after the viscoelastic solution (V1) disposed downstream from the diaphragm (10) has been dispensed in full.
