Benefits of technology

[0009] After the increase to a working value, the breast pump may operate at a steady value of positive and / or negative pressure that is adjustable in use, for example, is selected by a control operable by the user. In this case, the pressure may increase from the starting value to a fixed first working value, and then ramp from the first working value to the steady value selected by the user. The fixed first working value may then be within the range of values that can be selected for the steady value.
[0010] In the case of a breast pump in which positive and / or negative pressure is applied to the breast to stimulate it, and negative pressure is applied to the nipple to suck out milk, both pressures may increase from a starting value to a working value. The increases may take place over the same period of time.

Problems solved by technology

Merely attempting to suck milk from the nipple is much less effective, because the breast does not respond well.

Embodiment Construction

[0014] Referring to the accompanying drawings, where like numerals identify like elements, and initially to FIG. 1, one form of breast pump constructed in accordance with an embodiment of the invention, indicated generally by the reference number 20, comprises a breast cup 22, a pump 24, and a pump controller 26.

[0015] The breast cup 22 may be similar to those shown in U.S. Pat. No. 6,273,868 and U.S. Pat. App. No. 2003 / 0153869, in which a first air line 28 supplies negative pressure to a nipple tube 30 of the breast cup 22 in order to suck milk from the nipple into a collecting bottle 32, and at least one second air line 34 supplies air at positive and / or negative pressure to flexible chambers 36 in a conical part 38 of the breast cup 32. In this specification, pressures are described as positive or negative relative to ambient pressure, and are measured from ambient pressure as zero gauge. The chambers 36 may be formed of an elastomeric or other resilient material, so that they c...

Abstract

A breast pump comprises a breast cup and a source of positive and vacuum to the breast cup. The pressure and vacuum are set to an initial value for a fixed period of time, and they are nto adjustable by a user. The initial values are selected to allow the breast cup to be repositioned by a user before higher levels of pressure and vacuum are applied.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority to U.S. Provisional Patent Application No. 60 / 637,709, filed on Dec. 21, 2004, the disclosure of which is incorporated herein by reference.FIELD OF THE INVENTION [0002] The present invention is generally related to breast pumps for extracting milk from the breasts of human females. More particularly, the present invention is related to such a pump that is designed to massage the breast in order to promote the flow of milk. BACKGROUND OF THE INVENTION [0003] For various reasons, a lactating woman may wish to extract and collect her milk, and pumps designed for that purpose are well known. Such a pump typically comprises a cup or funnel that fits over the breast and a neck into which the nipple fits. The other end of the neck is connected to an intake of the actual pumping mechanism, which may be electric or hand operated. [0004] However, the human breast is adapted to respond optimally to suckling by a hu...
