TWO-COMPONENT SYRINGE FOR ONE HAND Russian patent published in 2020 - IPC A61M5/00 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment, namely to one-hand syringes intended for injections and other medical procedures associated with infusion or suction of fluid. Device represents a disposable syringe made of polymer material consisting of a body, a piston with a rod and a thrust for a finger. 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. To ensure passage of the anvil through the open end face of the body when assembling the syringe, the stop is articulated with the rod and brought into the working position perpendicular to the stock only after passing through the section of the body which does not have a longitudinal cutout. In the working position the support is fixed with a latch.

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.
