Benefits of technology

[0012]A significant, and heretofore unavailable advantage realized by the present invention is the ready ability to modify the breastpump suction action to a variety of desired conditions, and provide this ability to the end-user. An attendant advantage is that, as the science of breastpumping continues to make advances, new and improved suction curves and sequences can be made available on further cards, or other program-inputting means.

Problems solved by technology

Being manually driven, however, stroke rate and suction pressure produced can be uneven, and operating the pump can ultimately be tiring.

Embodiment Construction

The Breastpump Assembly

[0046]Referring to FIGS. 1 through 7 initially, a breastpump assembly of the present invention in one form has an aesthetically pleasing and compact design. The housing for the major components of the assembly is a casing 10 made of a rigid high impact plastic. As shown, it has a generally ellipsoidal cross-section along its vertical axis, yielding a pleasing smooth curving look to the casing exterior. The casing 10 is closed at its upper end by an upper housing part 11, to which is affixed a carrying handle 12.

[0047]In this first embodiment, carrying handle 12 has a pair of cradles 15 formed in opposite ends thereof. These cradles 15 are adapted to receive and support the funnel portions 16 of respective breastshields 17. These breastshields 17 (sometimes referred to themselves as breastpumps) are of the type shown and described in U.S. Pat. Nos. 4,964,851 and 4,929,229, for instance. Further detail regarding the breastshields 17 may be obtained through refer...

Abstract

A breastpump is provided with one or more novel suction sequences. which are considered to produce advantageous particularized results. Such sequences include a suction method for increased milk production and an improved suction method in general.

Description

[0001]This application is a continuation-in-part of U.S. patent application Ser. No. 09 / 476,076, filed Dec. 30, 1999, which claims the benefit of U.S. Provisional Application No. 60 / 170,070, filed Dec. 10, 1999.FIELD OF THE INVENTION[0002]This invention relates to breastpumps for drawing breastmilk, and particularly to a motorized, such as electrically driven, breastpump.BACKGROUND OF THE INVENTION[0003]Breastpumps for use by nursing mothers are well known. They allow the nursing woman to express the breastmilk as necessary or convenient, and further provide collection of the breastmilk for later use. For some mothers, breastpumps may be a necessity, such as when the child has suckling problems, or if the mother has problems with excessive or deficient milk production, or soreness, deformation or injury of the mammilla.[0004]Manual breastpumps are commonplace, primarily because they are relatively inexpensive and easy to transport. Being manually driven, however, stroke rate and suc...
