MULTIFLUID CONTINUOUS PUMPING DEVICE, DRIVE AND ACTUATING SYSTEMS, AND METHOD Russian patent published in 2017 - IPC A61M5/142 

Abstract RU 2624327 C2

FIELD: medicine.

SUBSTANCE: valve includes: a valve opening communicating for fluid discharge; the first outlet channel; the second outlet channel and a selector valve housing comprising a valve stem located in the valve bore and comprising a flow passage. At that, the selector valve body is configured to provide passage fluid communication for the flow in fluid communication with one of the first outlet channel and the second outlet channel, as well as with the closed position. At that, the flow passage contains a sealing device, selected from the group consisting of sealing collar device, elastomeric core, located in the thin-wall valve stem, multiple o-ring seals, segmented valve stem containing several pin elements between the radial ribs of the interactive socket, valve stem containing the lower part made of a compliant material and the upper part made of a rigid material, inner sleeve made of compliant sealing material, located in the valve hole between the valve cylinder outer wall and the valve stem, and an actuator coupling head with the ability to interface with the valve actuator connected to the drive and actuating system. At that, the valve actuator is designed to control the selector valve housing. At that, the said actuator coupling head and valve actuator are configured to engage only in one particular orientation.

EFFECT: efficiency enhancement.
