PUMPING DEVICE AND BREAST PUMP NODE Russian patent published in 2022 - IPC A61M1/06 F04B53/16 

FIELD: pumping devices.

SUBSTANCE: group of inventions relates to a pumping device and a breast pump node. Device (1), which can be used in the breast pump node, contains pump (10) made with the possibility of movement of fluid, case (40), in which pump (10) is placed, at least one channel (21, 22) for fluid transportation, passing between pump (10) and case (40), thereby connecting pump (10) to a place on case (40), in which at least one hole (41) is made in case (40) for providing a possibility of fluid passage, and installation structure (30) for installation of pump (10) in case (40). At least one channel (21, 22) is a part of structure (30) and has flexibility properties for reducing a degree of transmission of vibrations of pump (10) to case (40) via structure (30) during the operation of device (1). A part of structure (30) is a power supply element, which has flexibility properties for reducing a degree of transmission of vibrations of pump (10) to case (40) via structure (30) during the operation of device (1). The element is at least partially twisted into spiral.

EFFECT: group of inventions is aimed at reduction in noise during the operation of a pumping device.
