Abstract
Exemplary systems for small volume collection for a breastpump system are provided. The systems allow breast milk to flow directly from the breastshield to the collection container without leaving the control volume. A valve is present outside of the milk flow path that does not contact breast milk prior to the milk reaching a collection vessel.
Claims7
A system for small volume milk collection comprising:
- a breastshield having a first opening arranged at a first end for receiving at least a portion of a breast, a second opening at a second end configured to mate with a connector, a third opening arranged at a junction between the first opening and the second opening and extending through a side of the breastshield and a fourth opening arranged between the third opening and the second end, wherein the third opening is positioned within a first flow path for expressed breast milk and the fourth opening is positioned within a second flow path for the expressed breast milk, wherein the second flow path extends across the third opening to the fourth opening such that the first flow path is shorter than the second flow path;
- and a first collection container having a first end configured for removable attachment to the third opening of the breastshield, the fourth opening configured to connect to a second collection container;
- the first collection container being in fluid communication with an interior of the breastshield when attached to the third opening to form a liquid flow path for the expressed breast milk thereby, wherein the first collection container is configured to hold a volume of expressed breast milk not exceeding about 25 milliliters.
A method comprising:
- receiving colostrum and expressed breast milk via a breastshield of a breastpump system during a pumping operation, wherein the breastshield has a first opening arranged at a first end for receiving at least a portion of a breast, a second opening at a second end configured to mate with a connector, a third opening arranged at a junction between the first opening and the second opening and extending through a side of the breastshield and a fourth opening arranged between the third opening and the second end, wherein the third opening is positioned within a first flow path for expressed breast milk and the fourth opening is positioned within a second flow path for the expressed breast milk, wherein the second flow path extends across the third opening to the fourth opening such that the first flow path is shorter than the second flow path;
- collecting colostrum in a first collection container via the first flow path through an interior of the breastshield into the third opening, wherein the first collection container is a syringe-style container coupled to the third opening, wherein the syringe-style container is configured to be reachable by a user's hand while the user's hand holds the breastshield;
- and collecting the expressed breast milk in a second collection container via the second flow path through the breastshield into the fourth opening.
