SINGLE-HAND SYRINGE Russian patent published in 2019 - IPC A61M5/178 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment, namely to one-hand syringes. Device represents a disposable syringe made of polymer material consisting of a body, a piston with a rod and a thrust for a finger. Thrust during the syringe assembly is rigidly fixed in the eye on the free end of the rod perpendicular to its axis and, therefore, on one side is elevated above the side surface of the body. Length of the syringe body exceeds the length of the rod by more than two times; therefore, the finger support extends outward through the longitudinal cutout in the body wall that does not reach the open end, and is used for longitudinal movement of the piston with the rod within the cutout when collecting and discharging the liquid.

EFFECT: syringe is retained by circular grip of hand in any of the sections of the body, which do not have a cutout, which enables to perform fluid set and release with the thumb of the same hand without the need to change the position of the syringe relative to the hand.
