Abstract
A breastpump, manual or motorized, that includes a mechanism to regulate pressure change, e.g., vacuum, within a breastshield chamber, including in some cases to a maintained minimum pressure that is less than ambient (atmosphere). The pressure regulator provides control for varying negative pressure between a minimum value and a maximum value (and values in between), or to achieve a specific actually measured negative pressure value within a breastshield.
