FLUSHING SYSTEM Russian patent published in 2020 - IPC A61M25/00 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment. Catheter washing system comprises a feed line having a pump compartment, a discharge line having a pump compartment and a pump. Diameter d2 of discharge line pump compartment is less than diameter d1 of pump compartment of supply line to ensure interaction of pump with pump compartment of supply line to feed the flushing fluid into the catheter and to allow the pump to interact with the pumping compartment of the discharge line to withdraw the flushing fluid from the catheter. Provided is a bearing element, to which a supply line and a discharge line are fixed. Bearing element is located along the main extension plane, the supply line and the discharge line pass through the bearing element in the specified main extension plane, the bearing element has a hole. Pumping compartments of supply line and discharge line pass along hole. Pump is designed as a linear peristaltic pump; the pump has a cam shaft having a plurality of cams, each cam being coupled with a pin in motion. Each finger is made interacting with supply line and discharge line for fluid substance transfer, and pins are arranged in series compressing feed line and discharge line for fluid flow generation. Invention discloses cantilever for washing system, bearing element for flushing system and catheter pump system.

EFFECT: technical result consists in preventing formation of deposits in the catheter and simplifying the design.
