INFUSION SYSTEM AND ITS COMPONENTS Russian patent published in 2021 - IPC A61J1/20 A61M5/14 

FIELD: medicine.

SUBSTANCE: group of inventions relates to the field of medicine, namely to infusion systems for the delivery of several medicines to a patient. A system contains two tank sets, including an inlet connector made with the possibility of interaction with a medicine tank containing a tank port and a medicine, while the inlet connector is made with the possibility of connection to at least part of the port of the medicine tank. Each inlet connector contains a needle designed for receiving a medicine, and a meshing element made with the possibility of interaction with a part of the medicine tank to connect the inlet connector to the medicine tank. The first inlet connector additionally contains a check valve to ensure the flow of the medicine from the medicine tank in response to the application of threshold liquid pressure to the first medicine, which is greater than gravitationally induced hydrostatic pressure caused by the placement of the first tank set over a site of infusion to a patient. A set for infusion is also proposed, containing the specified system, as well as guide elements for inlet connectors made with the possibility of placement in a corresponding hole of a pump case and prevention of the insertion of the inlet connector into an erroneous receiving part of a pump tank.

EFFECT: invention ensures the correct direction of each medicine to a patient and prevents erroneous direction or cross-channeling of medicines.
