  • C-shaped heat pack for thermal treatment of breast
    Patent number: 6261313
    Abstract: The present invention relates to a C-shaped thermal heat pack for heating the female breast during post partum nursing and, more particularly, to a thermal heat pack which readily conforms to the contours of different sized female breasts to provide therapeutic heat to an adjacent breast to reduce swelling and irritation. The present invention overcomes the disadvantages of the prior art by providing a bendable thermal heat unit which assumes a cup or cone shape upon application to the breast. The present invention adjusts and conforms to various sizes of the female breasts to which it is to be applied. The present invention provides a layered conformable member with a C-shape having a selected indentation to permit formation of various sized rounded conical cups. A centrally located hole is provided for insertion of a nipple therethrough.
