LINEAR PERISTALTIC PUMP Russian patent published in 2017 - IPC A61M1/00 F04B43/12 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment. Improved linear peristaltic pump comprises central member mounted for rotation about a central shaft, several planetary gear mounted on axles in the central member, ring gear in a mesh engagement with each of the planetary gear, roller located on each of said planetary gear with an offset from the corresponding axis of the planetary gear. Flat compression surface located relative to said central shaft to allow insertion of flexible tube between the said flat surface compression and at least one of said several rollers. Motor is connected with the pump mechanism with possibility of relative rotation between the above central member and said ring gear so that said multiply rollers sequentially clamped flexible tube and move linearly along the said flat surface of the compression for pumping a fluid through a flexible tube. There are disclosed alternative versions of a peristaltic pump and transfer system for fluid using pump.

EFFECT: invention provide simplification and ease of use and production of the pump.
