MILK SUCKING SYSTEM Russian patent published in 2018 - IPC A61M1/06 

FIELD: medicine.

SUBSTANCE: invention relates to medical devices. Milk-sucking system comprises a breast pump comprising a funnel for receiving a mammary gland fluidly connected to the pump unit, vacuum channel for creating a pressure reduction on the mammary gland and a pump unit configured to generate a pressure reduction in the vacuum and discharge channel containing a vacuum pump configured to reduce pressure in the vacuum channel. Leakage opening is configured to allow a drop in pressure reduction at least in the portion of the vacuum channel, so that the pressure reduction at least in the portion of the vacuum channel is reset if the pump unit does not relieve the pressure drop in the vacuum channel. At that, the vacuum pump has an outlet port for discharging air coming from the vacuum channel. Leakage hole is located near the outlet port in such a way that the airflow from the outlet port is directed through the leakage port.

EFFECT: invention makes it possible to exclude injury and discomfort of the user, which may arise as a result of maintaining the vacuum acting on the mammary gland.
