Breast cup

A method for operating a breastpump unit for expression of human breastmilk, wherein the breastpump unit has a vacuum pump for generating pressures and at least one breast shield for sealing application to a breast to be pumped, wherein the breast shield has a flexible inner part having an inner chamber for receiving a nipple (W) of the breast and at least one outer chamber which at least partially surrounds the nipple (W), wherein a first pressure is applied to the inner chamber by the vacuum pump and at least one second pressure is applied to the at least one outer chamber by the vacuum pump, the method including pressurizing the flexible inner part such that the latter fits on the nipple (W) in an annular manner in a first position and such that it frees the nipple (W) in the radial direction in a second position.

A breastpump unit for expression of human breastmilk, wherein the breastpump unit has a vacuum pump for generating pressures and at least one breast shield for sealing application to a breast to be pumped, wherein the breast shield has an inner chamber for receiving a nipple (W) of the breast and also at least one outer chamber which at least partially surrounds the nipple (W), wherein the inner chamber is configured to be subjected to a first pressure by the vacuum pump and the at least one outer chamber is configured to be subjected to at least one second pressure by the vacuum pump, wherein the first pressure is an approximately temporally constant pressure and the at least one second pressure is a pulsating pressure.

A breast shield of a breastpump unit for expression of human breastmilk, wherein the breast shield has an application region for sealing application to the human breast and an inner chamber for receiving a nipple (W) of the breast, wherein the breast shield is provided with at least one sensor for determining the position of the nipple (W) and/or the position of a closure of the inner chamber during the pumping operation.

A breast shield of a breastpump unit for expression of human breastmilk, wherein the breastpump unit has a vacuum pump for generating pressures, wherein the breast shield has an application region for sealing application to the human breast and an inner chamber for receiving a nipple (W) of the breast, wherein the inner chamber has a longitudinal axis (L) and wherein the inner chamber collapses in accordance with an applied pressure, wherein the breast shield is provided with at least one sensor for determining the position with regard to the longitudinal axis (L) at which the inner chamber collapses.

A breast shield of a breastpump unit for expression of human breastmilk, wherein the breastpump unit has a vacuum pump for generating pressures, wherein the breast shield has an application region for sealing application to the human breast and an inner chamber for receiving a nipple (W) of the breast, characterized in that the application region ends in an encircling, soft and sealing pad on the breast side.

A breast shield of a breastpump unit for expression of human breastmilk, wherein the breast shield has an application region for sealing application to the human breast and an inner chamber for receiving a nipple (W) of the breast, wherein the breast shield has a receiving pocket on the breast side for collecting breastmilk drops when the breast shield is removed.

A breast shield of a breastpump unit for expression of human breastmilk, wherein the breastpump unit has a vacuum pump for generating pressures, wherein the breast shield has an outer breast shield body and a flexible inner part, wherein the flexible inner part

• forms an application region for sealing application to the human breast, and
• subdivides the breast shield into an inner chamber for receiving a nipple (W) of the breast and into at least one outer chamber which at least partially surrounds the nipple (W),
• wherein the inner chamber is configured to be subjected to a first pressure by the vacuum pump and the at least one outer chamber is configured to be subjected to at least one second pressure by the vacuum pump, wherein the flexible inner part is configured in one piece and the breast shield has a further chamber in the form of a cavity which is subdivided by the at least one outer chamber, wherein a fixed or releasable connection between the flexible inner part and the breast shield body forms an encircling partition wall, and wherein the additional chamber is arranged in the application region of the breast shield.

A breast shield of a breastpump unit for expression of human breastmilk, wherein the breastpump unit has a vacuum pump for generating pressures, wherein the breast shield defines a longitudinal axis (L), wherein the breast shield has an application region for sealing application to the human breast and an inner chamber for receiving a nipple (W) of the breast, wherein the inner chamber is bounded by an outer region which is formed in an asymmetrical manner, and in that at least one subregion of the outer region has an outer chamber, the inner side of which is able to be subjected to a pressure.

A breast shield unit of a breastpump unit for expression of human breastmilk, wherein the breastpump unit has a vacuum pump for generating pressures, wherein the breast shield unit comprises a breast shield having an interior space for receiving a nipple (W) and a flexible milk collection container, wherein the interior space has a first opening for receiving the nipple (W) and, as the only other opening, a connecting opening to the milk collection container, wherein the breast shield is connected to the milk collection container in an airtight manner via this opening, wherein means are provided which cyclically enlarge the interior space for the purpose of generating a negative pressure in the interior space for expression of the breastmilk.

A breast shield of a breastpump unit for expression of human breastmilk, wherein the breastpump unit has a vacuum pump for generating pressures, wherein the breast shield has an application region for sealing application to the human breast and an inner chamber for receiving a nipple (W) of the breast, wherein the breast shield also has a fan which blows air in the direction of the breast.
