Abstract

Claims (20)

1. A breast pump system, comprising:

a shell housing;

a chassis received in the shell housing;

a flange assembly including a nipple receiving portion, the nipple receiving portion including a terminal end configured with a flat window configured to allow visualization and confirmation of alignment of the flange assembly on a breast;

a plurality of magnets attached to one or more of the shell housing, the chassis and the flange, the plurality of magnets configured to provide attaching structure between the shell housing and chassis and the flange assembly; and

a sensor and a plurality of shunts, wherein the plurality of shunts are arranged to direct a magnetic field created by the plurality of magnets away from the sensor.

2. The system of claim 1 , wherein one or more of the plurality of magnets are exposed.

3. The system of claim 1 , wherein one or more of the plurality of magnets are hidden.

4. The system of claim 1 , wherein one or more of the plurality of magnets are coated.

5. The system of claim 1 , wherein the plurality of magnets or metal is positioned on both flange assembly and chassis and shell housing portions.

6. The system of claim 1 , wherein the flange assembly is formed from transparent material.

7. The system of claim 1 , wherein the flange assembly includes a magnet and the chassis includes a metal element or wherein the chassis includes a magnet and the flange includes a metal element.

8. The system of claim 1 , wherein the connection between the flange assembly, chassis and shell housing is sufficient to hold the flange assembly, chassis and shell housing together as the breast pump system is filled with milk.

9. The system of claim 1 , wherein the plurality of magnets provides a tactile or audible confirmation of attachment of the shell housing to the chassis and the flange assembly.

10. The system of claim 1 , wherein one or more of the chassis, shell housing and flange assembly are configured to accept additional magnets.

11. The system of claim 1 , further comprising a flange ring surrounding the nipple receiving portion of the flange assembly.

12. The system of claim 1 , wherein the shell housing includes a cut-out that provides visualization of the flange assembly and milk flow.

13. The system of claim 1 , wherein the flange assembly includes a scalloped portion arranged so that a user can visualize milk flow.

14. The system of claim 1 , further comprising a plurality of reaction plates attached to the flange assembly, the reaction plates being aligned with the magnets.

15. The system of claim 1 , the flange assembly further including an in-molded flange ring configured to facilitate confirming nipple alignment, the flange ring creating a contrast via light reflection to assist guiding a nipple into the nipple receiving portion.
