Problems solved by technology

The result is that less negative pressure may be used
[0005] Furthermore, almost all known breast pumps have the disadvantage of being made up of many parts, most of which also require cleaning
While they may generally be easy to handle, they are relatively bulky, which can be a hindrance especially for their transport, such as is the case in handbags
[0006] Due to the above drawbacks and the fact that the pumping process of known breast pumps differs substantially from the baby's natural sucking, many women find pumping unpleasant and thus prematurely end breastfeeding their infants

Embodiment Construction

[0030] alone figure 1 A typical embodiment of the breast pump of the present invention is shown in cross-section. The housing 1 has a helical peripheral wall and is preferably designed to be openable in order to remove components arranged therein for cleaning purposes. Thus, the housing 1 can be divided, for example, in a plane parallel to the drawing plane and the two half-shells can be connected to each other by a hinge. In the housing 1, a funnel 2 of soft elastic material, eg silicone, is arranged. The funnel 2 is mounted through its wide opening onto the peripheral housing edge 13 and thereby retracts into the interior of the housing 1 and down to the connecting section 9, as will be discussed in more detail below. Advantageously, the cross-section of the funnel 2 remains constant in the last section up to its inner end. It can thus be said that the last section of the funnel 2 is tubular. In the region of the opening of the funnel 2 a pressure chamber is arranged bet...

Abstract

A breast pump for collecting milk, comprising a funnel (2) for accommodating a breast, a casing (1), and a device for generating negative pressure. The funnel (2) comprises a flexible material and extends into the housing (1). Said means for generating negative pressure comprises at least one body (12) movable over a part of the length of said funnel (2) to compress said funnel (2).

Description

technical field [0001] The present invention relates to a breast pump for collecting milk comprising a funnel for receiving a breast, a housing, and a device for producing a pumping effect. Background technique [0002] Expressing milk and storing it for short periods of time allows the breastfeeding mother to become autonomous and uninhibited, and to work. Consequently, many different breast pumps have been developed, almost all of which employ pulsating negative pressure. More precisely, the pressure is typically reduced by 60 to 120 mbar at 1 to 2 Hz by means of a diaphragm pump. The pump is connected via tubing to the inside of a collection container similar to a baby bottle. The container has a funnel-shaped opening held opposite the breast. Due to the negative pressure, the teat is sucked into the funnel in a pulsating manner, which creates a suction effect on the areola, where the milk collects and is drawn out by the negative pressure through the teat. [0003] A...
