Breast pump bra structure to enhance airtightness and increase milk expression efficiency

Abstract

A milk production-enhancing bra structure for improving airtightness, characterized in that it comprises: a main body (10) with two cups (11) each designed to cover the breasts of a user; two shoulder straps (20), each having a first attachment section (21) detachably attached to a second attachment section (13) arranged on the corresponding cup (11); a first layer (111) arranged on an inner surface of the cup (11) and having a first contour layer (110), the first contour layer (110) being made of an elastic material and being attachable to the breast;and a second layer (112) arranged on an outer surface of the cup (11) and comprising a second contour layer (121) and a constriction section (122), wherein the second contour layer (121) is designed as a structure corresponding to the outer surface contour of an electric breast pump (30), and the constriction section (122) is arranged below the second contour layer (121); wherein, when the first attachment section (21) is attached to the second attachment section (13), the first contour layer (110) is attached to the breast; when the first attachment section (21) is separated from the second attachment section (13), the cup (11) forms an opening that allows the electric breast pump (30) to be positioned between the breast and the first layer (111);and when the first fastening section (21) and the second fastening section (13) are reattached, the second contour layer (121) is narrowed to be attached to an outer surface of the electric breast pump (30), and the narrowing section (122) is appropriately positioned on a lower edge of the electric breast pump (30) to exert a narrowing force on the electric breast pump (30) directed towards the breast, thereby improving the airtightness between the electric breast pump (30) and the breast.
