Abstract
A dosing syringe including a hollow cylindrical body and a plunger slidable within the hollow cylindrical body. The dosing syringe includes at least one slider slidable within a distal flange of the hollow cylindrical body transversely to the hollow cylindrical body and at least one wall is formed in the plunger for abutting and blocking the at least one slider during sliding of the at least one slider within the distal flange, wherein the at least one wall provides a mechanical stop which stops a stroke of the plunger at a predetermined volume of product to be aspirated and/or dispensed.
Claims13
A dosing syringe comprising:
- a hollow cylindrical body;
- a plunger slidable within the hollow cylindrical body;
- and
- at least one slider slidable within a distal flange of said hollow cylindrical body transversely to the hollow cylindrical body;
- wherein at least one wall is formed in the plunger for abutting and blocking the at least one slider during sliding of the at least one slider within the distal flange;
- wherein said at least one wall provides a mechanical stop configured to stop a stroke of said plunger at a predetermined volume of product to be aspirated and/or dispensed;
- wherein said at least one slider comprises a first portion projecting from the distal flange and a second portion projecting orthogonally from the first portion and housed within a respective slot of the distal flange;
- wherein longitudinal ribs are formed in said second portion, which are configured to slide within respective longitudinal grooves formed in the respective slot of the distal flange;
- wherein longitudinal and opposite grooves for blocking the at least one slider into position are formed in said respective slot of the distal flange;
- and
- wherein said longitudinal and opposite grooves have a complementary and slightly smaller shape than that of the longitudinal ribs.
A dosing syringe comprising:
- a hollow cylindrical body;
- a plunger slidable within the hollow cylindrical body;
- and
- at least one slider slidable within a distal flange of said hollow cylindrical body transversely to the hollow cylindrical body;
- wherein at least one wall is formed in the plunger for abutting and blocking the at least one slider during sliding of the at least one slider within the distal flange;
- wherein said at least one wall provides a mechanical stop configured to stop a stroke of said plunger at a predetermined volume of product to be aspirated and/or dispensed;
- wherein said hollow cylindrical body and said plunger have a circular cross section, the dosing syringe further comprising an anti-rotation element of the plunger within the hollow cylindrical body, the anti-rotation element comprising a plate-shaped element configured to be removably housed in a respective slot formed in the distal flange of the hollow cylindrical body on an opposite side to that on which a sliding housing slot of the at least one slider is formed, so as to abut against a wall formed in the plunger.
