Abstract
A pad for treating a perineal area of a woman before or after childbirth includes a foam layer and a substance integrated with the foam layer. The foam layer is flexible, so that it can conform to the perineal area of the woman. The pad may optionally include a skin contact layer made of an impermeable material. The foam layer and/or the optional skin contact layer may include openings, such as perforations or slits. A method of using the pad may involve placing the pad in the perineal area before or after childbirth. The pad may be frozen, cooled or heated before use, in different embodiments.
Claims30
A pad for treating a perineal area of a woman before or after childbirth, the pad comprising:
- an open cell foam layer having a width to fit within the perineal area;
- and
- a substance having a viscosity of at least 400 centipoise integrated with the open cell foam layer which provides a gel like consistency and allows passive diffusion of the substance through the open cell foam layer to give a uniform saturation, the substance comprising witch hazel, aloe vera, and water;
- wherein the open cell foam layer has a thickness of about 1 millimeter to about 30 millimeters such that the open cell foam layer is flexible and can conform to the perineal area of the woman when hydrated and frozen.
A method for treating a perineal area of a woman before or after childbirth, the method comprising:
- applying a pad to the perineal area, wherein the pad comprises:
- an open cell foam layer having a width to fit within the perineal area;
- and
- a substance having a viscosity of at least 400 centipoise integrated with the open cell foam layer which provides a gel like consistency and allows passive diffusion of the substance through the open cell foam layer to give a uniform saturation, the substance comprising witch hazel, aloe vera, and water;
- wherein the open cell foam layer has a thickness of about 1 millimeter to about 30 millimeters such that the open cell foam layer is flexible and can conform to the perineal area of the woman when hydrated and frozen;
- and
- leaving the pad in place on the perineal area for a period of time.
A pad for treating a perineal area of a woman before or after childbirth, the pad comprising:
- a skin contact layer;
- an open cell foam layer coupled with one side of the skin contact layer;
- and
- a substance having a viscosity of at least 400 centipoise integrated with the open cell foam layer which provides a gel like consistency and allows passive diffusion of the substance through the open cell foam layer to give a uniform saturation, the substance comprising witch hazel, aloe vera, and water;
- wherein the open cell foam layer has a thickness of about 1 millimeter to about 30 millimeters such that the foam layer is flexible, and can conform to the perineal area of the woman when hydrated and frozen.
A method for making a perineal pad for treating a perineal area of a woman before or after childbirth, the method comprising:
- providing an open cell foam layer having a width to fit within the perineal area and a thickness of about 1 millimeter to about 30 millimeters such that the open cell foam layer is flexible and can conform to the perineal area of the woman when hydrated and frozen;
- applying a substance having a viscosity of at least 400 centipoise to be integrated with the open cell foam layer which provides a gel like consistency and allows passive diffusion of the substance through the open cell foam layer to give a uniform saturation, the substance comprising witch hazel, aloe vera, and water, and allowing the substance to permeate partway into the open cell foam layer;
- and
- sealing the open cell foam layer inside a sealed package to allow the substance to further permeate into the open cell foam layer within the sealed package over time.
