摘要：
1. A syringe for dispensing a fluid, comprising a cylinder with an outlet end, wherein the outlet channel is formed, and a plunger disposed in a cylinder to be movable therein, so that the plunger and an outlet end forming a cavity of variable volume inside the cylinder and plunger can extrude fluid from the cavity through the outlet port, wherein the syringe further comprises a rotatable member which is rotatable about the longitudinal axis of the syringe, and which may be in a first angular position relative to the outlet end of the cylinder, and on the plunger and / or cylinder has a first abutment, restraining movement of the plunger in the first angular position of the rotary member and the rotary member may be in the second angular position of the outlet end of the cylinder, in which the action of the first detent stops, and the plunger can be moved to the second stop, the plunger is a rotatable element arranged to rotation between first and second angular positions, and has an element that controls the angular position which prevents rotation of the plunger from the first angular position into the second angular position until the piston abuts the first abutment.2. A syringe according to claim 1, wherein the member controlling the angular position, is a slot on the plunger, located, during use of the syringe, a spline groove formed in at least part of the cylinder.3. A syringe according to claim 2, wherein the cylinder comprises a flange at the end opposite the outlet end of the cylinder, and a spline groove is formed in the flange.4. A syringe according to claim 2, wherein the recess is formed in the slot, providing the plunger relative to the cylinder rotation around its longitudinal axis.5. A syringe according to claim 4, wherein the plunger includes a plurality of slots and each slot has an opening, wherein all the recesses are equidistant from one end of the plunger.6. A syringe according to claim 5, wherein the plunger includes a piston disposed within
