A breast shield having an adhesive inner surface for adhering to a woman's breast is disclosed. The breast shield may be connected to an adapter for transferring a vacuum generated by a pump to the breast. The adapter also allows milk expressed from the breast to drain from the adapter to a container. In the alternative, the breast shield may form part of a breast shield adapter system which is connected to a conventional breast shield by a drain line so that a conventional breast pump system is used to supply a vacuum and to collect the milk. ## Claims ### Claim 1 A breast shield adapter system consisting essentially of: a first adhesive breast shield having an opening, the first adhesive breast shield being configured for adhesive attachment of the breast shield to a woman's breast; a flexible elongate drain line having a first end and a second end, wherein the first end is disposed in communication with the breast shield opening for carrying milk from the breast shield opening to the second end of the drain line; and a connector disposed adjacent the second end of the drain line, wherein the connector is sized and shaped to nest in an opening of a second breast shield and/or second breast shield adapter which is part of a breast pump system; wherein the connector comprises two lumens. ### Claim 2 A breast shield adapter system comprising: a first adhesive breast shield having an opening, the first adhesive breast shield being configured for adhesive attachment of the breast shield to a woman's breast; a flexible elongate drain line having a first end and a second end, wherein the first end is disposed in communication with the breast shield opening for carrying milk from the breast shield opening to the second end of the drain line; and a connector disposed adjacent the second end of the drain line, wherein the connector is sized and shaped to nest in an opening of a second breast shield and/or second breast shield adapter which is part of a breast pump system; wherein the connector comprises two lumens; wherein the drain line is connected to the first adhesive breast shield by a coupling, the coupling having a first opening at a first end disposed adjacent the first adhesive breast shield, a second opening at a second end disposed in engagement with the flexible elongate drain line and a channel extending between the first opening and the second opening, the channel narrowing and turning downward as it extends between the first opening and the second opening. ### Claim 3 (depends on 1) The breast shield adapter system of claim 1, wherein the connector comprises a single lumen. ### Claim 4 (depends on 1) The breast shield adapter system of claim 1, wherein the connector further comprises a plug for selectively closing one lumen of the two lumens. ### Claim 5 (depends on 1) A breast milk collection system comprising the breast shield adapter system of claim 1, and further comprising a breast pump system having and at least one of a second breast shield-and a second breast shield adapter having the connector disposed therein, a container disposed in communication with the second breast shield or the second breast shield adapter for receiving milk therefrom; and a pump for selectively applying negative pressure through the second breast shield or the second breast shield adaptor. ### Claim 6 (depends on 1) The breast shield adapter system of claim 1, further comprising a coupling disposed between the first breast shield and the drain line, the drain line being attached on one end of the coupling and the first adhesive breast shield being attached to an opposing end of the coupling. ### Claim 7 A device for hands-free breast pumping comprising: a first adhesive breast shield having an inner surface with adhesive disposed thereon for holding the breast shield to a woman's breast and an opening through which milk from the breast may pass; and a drain line connected to the breast shield in communication with the opening for carrying the milk to a remote location, wherein the drain line is a flexible tube having a first end connected to the first adhesive breast shield and a second end; and a connector disposed adjacent the second end of the drain line, the connector being made of a resilient or semi-resilient material and being sized and shaped to nest in at least one of a breast shield and breast shield adapter and thereby form a seal with a breast pump system, the connector having at least one lumen therethrough for allowing the passage of breast milk through the connector; further comprising a coupling for attaching the first adhesive breast shield to the drain line, the coupling having a body having a first portion having a first opening disposed adjacent the first breast shield and a second portion having a second opening disposed generally opposite the first adhesive breast shield, the second portion being bent downwardly from the first portion and narrowing as it approaches the second opening. ### Claim 8 (depends on 7) The device of claim 7, wherein the drain line is a flexible tube between 6 and 24 inches long. ### Claim 9 A device for hands-free breast pumping comprising: a first adhesive breast shield having an inner surface with adhesive disposed thereon for holding the breast shield to a woman's breast and an opening through which milk from the breast may pass; and a drain line connected to the breast shield in communication with the opening for carrying the milk to a remote location, wherein the drain line is a flexible tube having a first end connected to the first adhesive breast shield and a second end; and a connector disposed adjacent the second end of the drain line, the connector being made of a resilient or semi-resilient material and being sized and shaped to nest in at least one of a breast shield and breast shield adapter and thereby form a seal with a breast pump system, the connector having at least one lumen therethrough for allowing the passage of breast milk through the connector; further comprising a coupling for attaching the first adhesive breast shield to the drain line, the coupling having a body having a first portion having a first opening disposed adjacent the first breast shield and a second portion having a second opening disposed generally opposite the first adhesive breast shield, the second portion being bent downwardly from the first portion and narrowing as it approaches the second opening; wherein the coupling extends through the opening in the first adhesive breast shield. ### Claim 10 (depends on 1) The breast shield adapter system of claim 1, wherein the connector has two generally parallel lumens extending therethrough and a plug for selectively closing one of the lumens. ### Claim 11 (depends on 10) The breast shield adapter system of claim 10, further comprising a second adhesive breast shield and a second drain line connected to the second adhesive breast shield, wherein the second drain line connected to the second adhesive breast shield is connected to one of the two lumens of the connector. ### Claim 12 (depends on 1) The breast shield adapter system of claim 1, wherein the first adhesive breast shield comprises a fragrance. ### Claim 13 (depends on 1) The breast shield adapter system of claim 1, wherein the two lumens of the connector are generally parallel. ### Claim 14 A breast pump system comprising: a breast shield configured for adhesive attachment to a woman's breast; a drain line disposed in communication with the breast shield for carrying milk from the breast to a remote location; and a resilient connector disposed on an end of the drain line generally opposite of the breast shield, the connector sized and shaped for attachment to a second breast shield and/or a second breast shield adapter which is part of a breast pump; and wherein the breast pump comprises a second breast shield or breast shield adapter having the connector disposed therein, a container disposed in communication with the second breast shield or the second breast shield adapter for receiving milk therefrom; and a pump for selectively applying negative pressure through the second breast shield or the second breast shield adaptor. ### Claim 15 (depends on 14) The breast pump system of claim 14, wherein the first breast shield is disposed on a first breast shield adapter and wherein the drain line has a first end attached to the first breast shield adapter, and a second end having the connector disposed thereon.
