Soft breastshield
A breastshield is constructed of a low Durometer material. The breastshield includes a nipple tunnel that generally accommodates the shape of a nipple and an aperture that conveys fluids through the breastshield.
1. A breastshield, wherein the improvement comprises: a soft breastshield constructed from a low Durometer material having a nipple receptacle volume defined therein wherein a woman's nipple is received in use, said breastshield being self-supporting such that said breastshield surrounding said nipple receptacle does not substantially collapse upon the nipple when said volume is subjected to vacuum in use, and wherein said soft breastshield has a Shore A hardness of less than about 20.
2. The breastshield of claim 1 wherein said soft breastshield is substantially solid with a nipple receptacle formed therein, said receptacle extending into a fluid conduit.
3. The breastshield of claim 1 wherein said soft breastshield is cylindrical in shape, substantially along its entire length, with said nipple receptacle extending into a nipple tunnel.
4. The breastshield of claim 1 , further having a changeable diameter.
5. The breastshield of claim 4 , further including one or more sizing rings sized to fit over an outside surface of said breastshield.
6. The breastshield of claim 4 , wherein said one or more sizing rings is a plurality of sizing rings, each having a different internal diameter.
7. A breastpump, comprising: a breastshield having a Shore A hardness of less than about 20 including a nipple opening at a first end extending into a nipple tunnel and which communicates with a fluid conduit of said breastpump, said breastshield not requiring any external supporting structure for said nipple tunnel to substantially retain its internal shape and volume under vacuum in use, wherein said nipple tunnel is sized and shaped to receive a nipple; a collection container for receiving fluid expressed from the nipple in communication with said fluid conduit; and a pressure source communicating with said nipple opening for applying an intermittent pressure thereto.
8. A breastshield made of a material having a Shore A hardness of less than about 20 and having a nipple receptacle volume defined therein wherein a woman's nipple is received in use, said breastshield being self-supporting such that said breastshield surrounding said nipple receptacle does not substantially collapse upon the nipple when said volume is subjected to vacuum in use.
9. A breastshield made of a material having a Shore A hardness of less than about 10 and having a nipple receptacle volume defined therein wherein a woman's nipple is received in use, said breastshield being self-supporting such that said breastshield surrounding said nipple receptacle does not substantially collapse upon the nipple when said volume is subjected to vacuum in use.
10. A breastshield made of a material having a Shore 00 hardness in the range of about 20 to about 45 and having a nipple receptacle volume defined therein wherein a woman's nipple is received in use, said breastshield being self-supporting such that said breastshield surrounding said nipple receptacle does not substantially collapse upon the nipple when said volume is subjected to vacuum in use.
11. A breastshield comprising: an elongated breastshield member having a nipple receptacle at one end of a nipple tunnel, said nipple tunnel extending along a longitudinal length of said breastshield member and wherein said breastshield member is formed of a flexible material that is bendable in use, and wherein said soft breastshield having a nipple receptacle volume defined therein wherein a woman's nipple is received in use, said breastshield being self-supporting such that said breastshield surrounding said nipple receptacle does not substantially collapse upon the nipple when said volume is subjected to vacuum in use, and cylindrical in shape substantially along its elongated length.
12. The breastshield of claim 11 wherein said breastshield member is curved along said longitudinal length.
13. The breastshield of claim 11 wherein an adjustable ring is positioned on an outside wall of said nipple tunnel.
14. The breastshield of claim 11 wherein one of a plurality of rings is positioned on an outside wall of said nipple tunnel and wherein each of said plurality of rings has different internal diameters.
