摘要：
1. A syringe including:! a syringe barrel having an inner surface forming a cavity, an open proximal end, a distal end and an outlet near the distal end in communication with the cavity； ! a piston located at least partially inside the syringe barrel and having an elongated piston rod and a piston head with a distal sealing surface and a proximal end surface that has a continuous perimeter line, the piston rod and piston head being connected as a whole； and! an annular locking element located on the inner surface of the cylinder of the syringe, protruding into the cylinder cavity and forming an interaction surface around the perimeter of the cylinder cavity, and the annular locking element is configured to interact with the piston head and hold it in the locked position at least partially inside the cylinder cavity； ! moreover, the interaction surface of the annular locking element is adjacent to the surface of the proximal end of the piston head along the entire continuous line of its perimeter when the piston head is in the locked position. ! 2. The syringe according to claim 1, in which the width of the head of the syringe on the distal sealing surface slightly exceeds the width of the cavity of the cylinder of the syringe. ! 3. The syringe according to claim 1, in which the interaction surface of the annular locking element is continuous along the perimeter line of the cylinder cavity and the annular locking element abuts the surface of the proximal end of the piston head without gaps along the entire continuous line of its perimeter when the piston head is in the locked position. ! 4. The syringe according to claim 1, in which the annular locking e1. Шприц, включающий: ! цилиндр шприца, имеющий внутреннюю поверхность, формирующую полость, открытый проксимальный конец, дистальный конец и выходное отверстие возле дистального конца, сообщающееся с полостью； ! поршень, расположенный по меньшей мере частично внутри цилиндра шприца и имеющий удлиненный шток поршня
