PUMP DEVICE MADE TO BE USED WITH A BREAST PUMP Russian patent published in 2023 - IPC A61M1/00 A61M1/06 

FIELD: medical equipment.

SUBSTANCE: pump device is configured to be used with a breast pump comprising a milk pumping set configured to expose the device user's chest to a pressure profile and to receive milk expressed from the breast. The pumping device includes a pumping element configured to create a pressure profile in the milk pumping set. The pump element has a suction side and an outlet side, an air channel system comprising an air duct of the milk pumping set configured to provide an air connection of the milk pumping set to the pumping device and connected between the pumping set by the suction side of the pumping element. The volume element is configured to accumulate vacuum in the pumping device. The storage switching mechanism is located between the suction side of the pumping device and the air duct of the pumping set and the volume element and is configured to switch between the position of direct connection of the air passage of the milk pumping set with the volume element in a bypass position with respect to the pumping element and the disconnection position the air channel of the pumping set from the volume element. The surrounding switching mechanism is located between the suction side of the pumping device and the air duct of the pumping set and the environment of the pumping device and is configured to switch between the position of connecting the air duct of the pumping set to the surrounding media of the pumping device and the position of disconnecting the air pumping set duct from the surrounding media of the pumping device. A breast pump and a method of operation of the pumping device.

EFFECT: reduction of the size and save energy.
