Problems solved by technology

so she doesn't have free hands to activate the breast pump
However, if she switches on the breast pump first and only then places the breastshield on the breasts, the negative pressure already created prevents optimal and pain-free placement of the breastshield on both breasts for the mother

Embodiment Construction

[0025] figure 1 A breast pump according to the invention is shown with a housing 1 and a suction connection 13 . Two suction hoses 2 are inserted into the suction connection 13 , which are each led to a breastshield 3 .

[0026] as in figure 2 As can be seen in the housing 1 , a pump assembly 15 with an electric motor, a control unit 14 for controlling the pump assembly 15 , and a display control device 16 are provided in the housing 1 . A connecting channel 12 , usually a hose, leads from the pump assembly 15 to the suction connection 13 . In other embodiments, the pump assembly itself terminates at the suction connection 13 . The control unit 14 has a time delay module, for example a circuit with one or more relays.

[0027] Also arranged on or in the housing 1 is a display unit, here in the form of a display 10, as in figure 1 identifiable in. Furthermore, a switch 11 is present. In this example, the switch 11 is used to switch the breast pump on and off and at the ...

Abstract

An electrically operated breast pump for pumping human breast milk comprises an electrical pump unit (15) and an electronic control unit (14) for controlling the pump unit (15). The pump unit (15) can be activated by the control unit (14) in a time-delayed manner. The breast pump according to the invention allows a stress-free start of the process of pumping breast milk in a simple manner.

Description

technical field [0001] The present invention relates to an electrically driven breast pump for pumping human breast milk. Background technique [0002] Breast pumps for expressing human breast milk are well known. There are basically two different types: the first is manually driven, ie the negative pressure required for pumping is generated by manually operating the vacuum pump. In the second category there are electric pump assemblies which have an electric motor in order to be able to generate the required vacuum. [0003] Electrically driven breast pumps are of varying complexity in terms of their control. There are simple-acting breast pumps which apply a constant, pulsating vacuum to the breast pump, wherein the pumping frequency and the strength of the suction can generally be selected. Other breast pumps can be programmed with relatively complex suction curves in order to be able to produce as realistic a pumping behavior as possible. Many of these pumps also off...
