BREAST PUMP Russian patent published in 2021 - IPC A61M1/06 

FIELD: medical equipment.

SUBSTANCE: breast pump (1) for extracting breast milk from the human breast contains pumping kit (2) containing funnel (23) for receiving the breast, milk outlet (24), air outlet (27) and device (26) for preventing milk leakage connected to air outlet (27), which is a partition for human breast milk, allowing air to pass through. Vacuum unit (3) contains air inlet (35), pump (31) for sucking air out of funnel (23) for receiving the breast in kit (2) through air outlet (27) in kit (2) and inlet (35) in vacuum unit (3), as well as electric engine (32) for powering pump (31). A channel is used to establish an air path between air outlet (27) in kit (2) for pumping and air inlet (35) in vacuum unit (3). Control system (33, 34) controls the operation of engine (32) to actuate pump (31), in particular, to control the supply of power to engine (32). Control system (33, 34) contains a microcontroller and memory containing programmed information about the reference value of at least one operating characteristic of the engine and the maximum permissible deviation of the reference value of at least one operating characteristic from the detected at least one operating characteristic. Control system (33, 34) is made with the possibility of: detecting at least one operating characteristic of engine (32), comparing the detected at least one operating characteristic with the reference value of at least one operating characteristic during the operation of breast pump (1), as well as stopping the power supply to engine (32), if it follows from comparison results that the deviation of at least one operating characteristic from the reference value is greater than the specified maximum deviation. Connector (6, 7) contains milk catcher (61, 71), and it is made of transparent material. The breast pump case is also made of transparent material.

EFFECT: providing measures to prevent the penetration of milk that has flowed through the air outlet in the pumping kit into the vacuum unit.
