SYRINGE FOR IMPLANT Russian patent published in 2020 - IPC A61M5/315 

FIELD: medical equipment.

SUBSTANCE: invention refers to syringes for implant. Implant syringe has an injection needle holder that holds an injection needle, an axially adjacent portion intended for placement of the preparation, and outer sleeve with front gripping section radially protruding on its rear end section. At that, holder of injection needle and outer sleeve are connected to each other for joint axial movement, inner sleeve, on which the outer sleeve is movably mounted and in which the movable injection needle with the part intended for placement is made. At that, the inner sleeve has axial slots, which penetrate the ribs, which connect the external sleeve to the holder of the injection needle, besides, rod-shaped piston, which is attached to rear gripping portion and partially enveloped by rear sleeve, which movably enters inner sleeve, wherein the rod-shaped piston is movable through the portion intended for placement of the preparation into the injection needle so that a distance is left between the tip of the injection needle and the head end of the piston, which is approximately equal to the length of the preparation to be administered, and the piston forward movement is limited by the fact that the rear gripping section reaches the back lateral edge of the inner sleeve. At that, outer sleeve in advanced initial position with free-lying injection needle with possibility of release is blocked by means of locking device, which is located on inner sleeve and protrudes radially outward, and when moving back sleeve in its end position locking device moves radially inward, as a result, outer sleeve is released and by means of front gripping section is retracted back on inner sleeve.

EFFECT: disclosed is syringe for implant.
