CONNECTING DEVICE Russian patent published in 2021 - IPC A61M5/158 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine, to connecting devices for liquid connection of various components of an outpatient infusion pump system, and to connectors of such connecting devices. The first connector (FC) for establishing a liquid connection with the second connector contains a valve with a seat having a valve chamber and a round hole with an annular sealing edge, a shut-off element located in the valve chamber and capable of hermetically closing it when pressed against the round hole of the valve seat, and an elastic element applying a constant force to the valve shut-off element, pressing the valve shut-off element against the round hole of the valve seat. The valve seat contains an annular wall extending around the round hole and located on the opposite side of the round hole to the valve chamber. The annular wall forms a concave socket for receiving the corresponding connecting cone of the second connector, the concave socket having the shape of a truncated cone and facing away from the valve chamber, and the round hole is located in the center of the concave socket. A second connector for establishing a liquid connection with the first connector is also proposed, containing a straight circular truncated cone placed in the corresponding concave socket of the first connector, a recess in the small base of the truncated cone for acting on the shut-off element of the valve of the first connector and a liquid infeed channel. The liquid infeed channel has one or more outlets that open at least partially on the side surface of the cone.

EFFECT: long-term infusion of liquid medications to the patient. Safety and efficiency of use.
