Abstract

The invention relates to medical equipment, in particular to single-use devices for injection. The syringe consists of a needle, a barrel, a plunger, and a plunger stopper. The plunger with the plunger stopper has the same length as the syringe barrel and a specific form of a cylindrical handle stop. In order to release the solution, the syringe has not one but several small holes allowing the solution to pass through smoothly, while preventing the plunger from being pushed out from the needle fitting tip. The technical result consists in preventing reuse of the syringe with full immersion of the plunger.

Claims

1. A single-use syringe, comprising a needle, a barrel, a plunger stopper with a plunger, and a handle stop which is cylinder-shaped with a diameter equal to an inner diameter of the barrel, which does not allow the plunger to be moved to its operational position after complete injection of a solution, wherein the syringe has more than one openings for the solution to be released thus preventing the plunger stopper with a plunger from pushing on a side of a needle fitting.
