FIELD: medicine.
SUBSTANCE: group of inventions relates to medical equipment. Pump unit for a breast pump for expressing milk from a human breast comprises an electric motor for actuating a pump assembly which is configured to provide a feedback signal of the electric motor. Control unit serves to provide control signal to control electric motor. Calculation module is used to calculate the pressure provided by the pump unit based on the feedback signal of the electric motor and the control signal. Control unit is configured to obtain the required pressure set by the user through a user interface or predetermined in the pump unit, and control signal adjustment based on difference between said required pressure and design pressure. Disclosed is a method of controlling pressure created by a pump unit.
EFFECT: invention enables accurate and reliable control of the pressure provided by the pump.
