  • Patent number: 9078962
    Abstract: The invention provides a breast pump capable of effectively preventing the occurrence of leaking of breast milk from a milk expressing section having an enlarged diameter during expression of milk, and also effectively preventing the loss of negative pressure due to leaking. A breast pump has an accommodating vessel for collecting breast milk; a breast pump main body which generates negative pressure for expressing milk; an enlarged-diameter milk expressing section having an enlarged diameter for abutting against a breast of a user; and a shock absorbing section, at least a portion of which abuts against a breast of a user by being formed in a substantially circular trumpet shape following an opening section of the enlarged-diameter milk expressing section, wherein the shock absorbing section includes an abutting section which abuts against an areola of the user and a tight contact section which makes tight contact with the user's breast.

  • 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: 7857153
    Abstract: An artificial nipple can include a nipple body portion connected to a mounting structure that is configured for mounting the nipple on an infant feeding bottle. A mammary papilla leading end portion can be disposed at the leading end portion of a mammary papilla portion and have a leading end opening portion. The inner layer on the inner side of the wall is formed of a shape holding layer made of a material having a rigidity capable of holding the wall shape. The outer layer on the surface side of the wall is formed of a tongue abutting layer having a smooth face. Between the shape holding layer and the tongue abutting layer there is disposed a deformation absorbing layer which is made of a material having a lower rigidity than that of the material of the shape holding layer and the tongue abutting layer.
