Abstract

Изобретение относитс  к медицинской технике, точнее к насосным устройствам с пульсирующим потоком рабочей жидкости. Цель изобретени  - снижение травмы форменных элементов путем неполного последовательного дискретного пережати  трубки. Перистальтический насос содержит трубку 4, установленную по винтовой линии в корпусе 8 с возможностью ее пережати  пальцами, которые последовательно нажимают на трубку 4 от сближени  шнеков 14 и 15 по мере вращени  коаксиальных цилиндров 12 и 13 против часовой стрелки. Неполное пережатие трубки по длине, определ ющей объем изгнани  рабочей жидкости, например крови, обеспечивает уменьшение гемолиза. 4 ил.The invention relates to medical technology, more specifically to pumping devices with a pulsating flow of working fluid. The purpose of the invention is to reduce the injury of shaped elements by incomplete sequential discrete squeezing of the tube. The peristaltic pump contains a tube 4 mounted along a helical line in the housing 8 with the possibility of pressing it with fingers, which successively press the tube 4 against the approach of screws 14 and 15 as the coaxial cylinders 12 and 13 rotate counterclockwise. Incomplete clamping of the tube along the length that determines the volume of expulsion of the working fluid, such as blood, provides for a reduction in hemolysis. 4 il.
