AI Technical Summary
Wearable breast pumps cannot pump milk properly due to misalignment between the vent and the breast, and current technology cannot meet the usage needs and comfort requirements of different users.
A breast pumping device was designed, including a fitting, an elastic diaphragm, a horn cover, and a one-way valve for expressing milk. By creating a negative pressure environment, the horn cover is firmly attached to the breast. The pressure inside the sealed cavity is adjusted by using side perforations. Combined with sensors to detect air leakage and adjust the negative pressure, stable attachment and comfort are ensured.
It effectively prevents the breast pump from slipping down relative to the breast, meets the needs of different users, and improves pumping efficiency and comfort.
