Abstract: The present technology is a device for delivering a medicinal agent to a breastfeeding child. One embodiment comprises a first portion configured to be positioned on the breast during breastfeeding a second portion having an agent region and a sealing region. The agent region is configured to house the agent during breastfeeding and has a first cross-sectional area. The sealing region has a second cross-sectional area at least great enough to surround and engage a circumference of the nipple but less than the first cross-sectional area. When the device is positioned on the breast and the child is breastfeeding, the device is configured such that the nipple extends through the sealing region into the agent region and the portion of the delivery device at the sealing region contacts the nipple, thereby reducing or preventing the flow of breast milk and/or the agent through the sealing region to the first portion.

Abstract: Systems, devices, and methods for delivering a therapeutic or other agent to a breastfeeding child are disclosed herein. A delivery system configured in accordance with the present technology can include, for example, a wearable device configured to be positioned on a breast during breastfeeding. The system can further include an agent source configured to house the agent and a fluid source configured to supply a supplemental fluid. The agent source and fluid source can be fluidly coupled to the wearable device via a connector. When the device is positioned on the breast and the child is breastfeeding, the supplemental fluid mixes with the agent and flows through the connector into the wearable device and into the mouth of the breastfeeding child.
