  • Patent number: 8608685
    Abstract: A breast pump can be configured to be capable of easily attaching/detaching a primary side serving as a sealed space which is in communication with a milking space and allows the passage of breast milk, with a secondary side in which a case is connected with a pressure changing apparatus. The breast pump can include a breast pump main body connected to the pressure changing apparatus by a conduit, wherein a milking part is disposed so as to liquid-tightly separate a sealed space (or a space that is in fluid communication with the sealed space), and the pressure changing apparatus from each other. A pressure transmission part for transmitting pressure changed by the pressure changing apparatus can be provided. The pressure transmission part can include a deformable part where a volume in the sealed space can be deformed by a pressure fluctuation generated by the pressure changing apparatus.

  • Patent number: 8221373
    Abstract: A breast-milk pad can be produced relatively easily, such that it reduces an uncomfortable sensation to the skin surface of a user, and has excellent shape retention properties. A method for producing the breast-milk pad is also disclosed. The breast-milk pad can include a material that is made up by stacking: a back sheet that prevents permeation of liquid; a top sheet that contacts the body; and an absorber that is disposed between the back sheet and the top sheet. The top sheet and the back sheet are bonded to each other in an outer peripheral portion. Cutout portions obtained by cutting the absorber can be formed in positions facing each other at the outer peripheral portion such that cutout width of each of the cutout portions gradually narrows down inwardly.
