Abstract

A disclosed reclining breast pumping system includes a breast shield that forms a passageway. Material of the breast shield adjacent to a first end of the passageway is shaped to fit over an area surrounding the areola and nipple of a woman'"'"'s breast. Material of the breast shield that extends from a second end of the passageway is formed into a tube. When the breast shield is fitted onto a woman'"'"'s breast, the part of the passageway closest to but not touching the nipple of the breast extends in a direction that is non-perpendicular to the areola. Variations and methods are also disclosed.

Claims

1. A method for a woman to express breast milk, comprising:

(a) placing a breast shield over an area surrounding the areola and nipple of a breast of the woman, wherein the breast shield forms a passageway and;

(1) material adjacent to a first end of the passageway is shaped to fit over the area surrounding the areola and nipple while allowing them to move relative to the material,

(2) material of the breast shield extending from a second end of the passageway is formed into a tube, and

(3) the passageway formed by the part of the tube closest to but not touching the nipple when the shield is so placed extends in a direction non-perpendicular to the areola;

(b) orienting the breast shield such that the passageway formed by the part of the tube closest to the nipple extends downward; and

(c) expressing milk from the breast through the tube while reclining.

2. The method of claim 1 wherein placing the breast shield further comprises using a breast shield suspended from a strap about the woman'"'"'s neck.

3. The method of claim 2 wherein placing the breast shield further comprises using a breast shield coupled to the strap with a trapeze support structure and a flexible cord.

4. The method of claim 1 further comprising repeating parts (a) through (c) for a second breast shield placed over an area surrounding the areola and nipple of the other breast of the woman.

5. The method of claim 4 further comprising suspending the breast shields from a strap placed about the woman'"'"'s neck.

6. The method of claim 5 wherein placing the two breast shields further comprises using a pair of breast shields coupled to the strap with a trapeze support structure and a flexible cord.

7. The method of claim 6 wherein placing the two breast shields further comprises using breast shields having the part of the passageway formed by the tube closest to the nipple having an elliptical cross-section, in a plane parallel to the areola, with a length that is about twice its width.

8. The method of claim 6 wherein placing the two breast shields comprises using breast shields having material adjacent to the first end of the passageway that includes a plurality of ripples at varying radii about the passageway.

9. The method of claim 1 wherein placing the breast shield comprises using a shield having the passageway formed by the part of the tube closest to the nipple extending in a direction that is between about 20 and 40 degrees from perpendicular to the areola.

10. The method of claim 9 wherein placing the breast shield comprises using a shield having the passageway formed by the part of the tube closest to the nipple extending in a direction that is about 26 degrees from perpendicular to the areola.

11. The method of claim 1 wherein material shaped to fit over the area surrounding the areola and nipple transitions gradually to being formed into a tube, whereby abrupt edges are avoided around the nipple.

12. An apparatus comprising:

(a) a flexible strap; and

(b) a breast shield coupled to the strap and forming a passageway, wherein;

(1) material of the breast shield extending from one end of the passageway is shaped to fit over an area surrounding the areola and nipple of a woman'"'"'s breast while allowing them to move relative to the material, and

(2) material of the breast shield extending from the other end of the passageway is formed into a tube;

(c) wherein, when the breast shield is fitted onto the breast, the passageway formed by the part of the tube closest to but not touching the nipple extends in a direction non-perpendicular to the areola.

13. The apparatus of claim 12 wherein the direction is between about 20 and 40 degrees from perpendicular to the areola.

14. The apparatus of claim 13 wherein the direction is about 26 degrees from perpendicular to the areola.

15. The apparatus of claim 12 wherein the part of the passageway formed by the tube closest to but not touching the nipple has an elliptical cross-section, in a plane parallel to the areola, with a length that is about twice its width.

16. The apparatus of claim 12 further comprising a trapeze support structure connecting the breast shield to the flexible cord.

17. The apparatus of claim 12 further comprising:

(a) a second breast shield like the first and a second flexible cord connecting the second breast shield to the strap; and

(b) a pair of trapeze support structures that each connect one of the breast shields to one of the flexible cords.

18. A breast shield forming a passageway, wherein:

(a) material of the breast shield extending from one end of the passageway includes a plurality of ripples at varying radii about the passageway and is shaped to fit over an area surrounding the areola and nipple of a woman'"'"'s breast while allowing them to move relative to the material;

(b) material of the breast shield extending from the other end of the passageway is formed into a tube;

(c) the breast shield is shaped such that, when it is fitted onto the breast, the passageway formed by the part of the tube closest to but not touching the nipple extends in a direction non-perpendicular to the areola.

19. The breast shield of claim 18 wherein the plurality of ripples includes three or more ripples.

20. The breast shield of claim 18 wherein the ripples extend only partially around the passageway.

21. The breast shield of claim 20 wherein the ripples extend about two thirds of the way around the passageway.
