Abstract
An improved breastshield for breastpumps has a tubular extension with a non-circular internal contour such as an oval, polygonal or fluted shape, among others. In another aspect of the invention, the non-circular contour is provided in the main breast-receiving part of the breastshield. Surface features, such as protuberances, are further provided for the breastshield which yield a non-smooth tactile feel to the breastshield.
Claims5
An improved breastshield having a generally rigid breast-receiving portion with a generally rigid extension within which a nipple is receivable, comprising:
- an interior contour for said breast-receiving portion upon which are formed a combination of at least two types in plurality of different-shaped surface features selected from a group consisting of hemispherical bumps, elongate humps, ridges and ribs, over which a breast moves in use of the breastshield and wherein said surface features are also formed in said extension over which a nipple moves in use of the breastshield.
An improved breastshield for a breastpump comprising:
- a main breast-receiving portion having a downstream opening, an exterior and an interior;
- a generally rigid tubular extension, which does not collapse and retains its shape during use, having a proximal end that extends from and communicates with the opening of the breast-receiving portion;
- said tubular extension having an interior sidewall surface with a non-circular circumferential contour along at least a part of an axial length of said tubular extension adjacent said proximal end, wherein said non-circular circumferential contour is triangular in shape.
An improved breastshield for a breastpump comprising:
- a main breast-receiving portion having a downstream opening, an exterior and an interior;
- a generally rigid tubular extension, which does not collapse and retains its shape during use, having a proximal end that extends from and communicates with the opening of the breast-receiving portion;
- said tubular extension having an interior sidewall surface with a non-circular circumferential contour along at least a part of an axial length of said tubular extension adjacent said proximal end, wherein said non-circular circumferential contour is rectangular in shape.
An improved breastshield for a breastpump comprising:
- a main breast-receiving portion having a downstream opening, an exterior and an interior;
- a generally rigid tubular extension, which does not collapse and retains its shape during use, having a proximal end that extends from and communicates with the opening of the breast-receiving portion;
- said tubular extension having an interior sidewall surface with a non-circular circumferential contour along at least a part of an axial length of said tubular extension adjacent said proximal end, wherein said non-circular circumferential contour is pentagonal in shape.
An improved breastshield for a breastpump comprising:
- main breast-receiving portion having a downstream opening, an exterior and an interior;
- a generally rigid tubular extension, which does not collapse and retains its shape during use, having a proximal end that extends from and communicates with the opening of the breast-receiving portion;
- said tubular extension having an interior sidewall surface with a non-circular circumferential contour along at least a part of an axial length of said tubular extension adjacent said proximal end, wherein said non-circular circumferential contour is hexagonal in shape.
