Surgical recovery brassiere

The present invention, in the preferred embodiment, is a surgery recovery brassiere which resolves many of the problems faced by women who have undergone breast surgery and particularly, mastectomy. The present invention comprises front panels, prosthesis panels, rear panels, torso band, straps, drain tube apertures and fluid collection storage pouch.More specifically, two front panels each comprise a cup portion and a conforming portion. The prosthesis panels are attached to the rear facing of the cup portion of the front panel to form enclosed pockets to hold one or two prosthesis. Each of the two rear panels are joined at one end to the front panels and extend to meet the opposing rear panel at a back closure. The free end of each of the front panels meet to form a front closure. Straps extend from the top of the front panel to the top of the adjacent rear panel. The torso band extends around the lower edge of the surgery recovery brassiere to form an almost continuous strip of material along the lower edge of the front and rear panels.The surgery recovery brassiere further accommodates post-operative surgical drainage systems composed of one or more drain tubes and associated fluid collection bulbs. The position of drainage tube apertures, generally located proximate to the joint between the front and rear panels, allow drainage tubes to protrude from the chest wall, through the apertures and into the collection storage pouch. Tab closures allow the wearer to secure the drainage tubes within the aperture to further reduce movement of the tubes and disturbance of the drainage system. The storage pouch provides pockets with elastic top entry so that collection bulbs are within easy, convenient reach for emptying lymphatic fluids and other waste materials. The upper edge of the storage pouch releasably attaches to the torso band with a hook-and-loop fastener system.

Pad for use with continent ostomy port

A continent ostomy port device has a generally planar face plate defining a selectively sealable aperture which is alignable with the opening of a stoma formed in the body of a user of the device. A closure portion is connected to the generally planar face plate adjacent to the aperture and is adapted to permit selective and repeatable covering and uncovering of the aperture in the generally planar face plate. A catheter portion extends from one side of the face plate and extends proximally, and one end of the catheter portion is disposed interior of the user's body, within the ostomy site, when the port device is in normal use position. The catheter portion has continuous and generally cylindrical exterior and interior side walls, the latter defining a major lumen. The catheter portion is sized and shaped appropriately for non-surgical insertion through a stoma to a sufficient distance that the presence of the catheter portion within the stoma provides a physical barrier which reduces the incidence of stoma prolapse, without the use of extraneous, externally applied materials or additional surgery. A removable cartridge is sized and shaped to fit snugly and slideably within the major lumen of the catheter portion of the device so as to be liquid-tight and to thereby prevent inadvertent escape of body waste material from the stoma through the device when the cartridge is in place, so that the user is not required to wear an ostomy bag, and to further thereby clean the interior side wall of the catheter portion as the cartridge is pressed into the major lumen of the catheter. A selectively operable anti-reflux valve that is attached internally of the proximal end of the catheter portion and is activated when it is desired to prevent escape of body waste through the port device, and deactivated when it is desired to permit passage of fluid through the port device. Retaining structure is connected to the catheter, and is non-surgically, snugly fittable into the stoma, to cause the port device to be self-retaining in a normal use position within a stoma of the user, without the need for special surgery and extraneous, external fixation materials such as tape, belts, and adhesives.

Nasal Dilator and Method of Manufacture

A nasal dilator comprises a laminate of vertically stacked layers forming a unitary, or single body, truss where each layer includes at least one member. The truss features horizontal regions adapted to engage outer wall tissues of first and second nasal passages and to traverse the bridge of a nose therebetween. When in use the dilator acts to stabilize and/or expand the nasal outer wall tissues and prevent said tissues from drawing inward during breathing. Manufacturing methods produce dilator layers and/or finished nasal dilator devices efficiently at the same or lower cost as traditional methods by fabricating dilator elements in whole or part along common lines or edges. Said common lines define peripheral dimensions and form spaced apart relationships between dilator layers, members and finished dilator devices without sacrificing usable material to do so. Manufacturing steps include cutting through a fabrication laminate along lines defining at least portions of one or more layers, members, and the truss's peripheral edges. Manufacturing methods further maximize material usage by incorporating waste material into a subsequent fabrication process. Dilator embodiments further include means for providing disparate dilating force to opposing nasal passages, and means for incorporating promotional printing into the dilator fabrication process.

Method and apparatus for producing superheated steam using heat from the incineration of waste material

PCT No. PCT/JP97/00573 Sec. 371 Date Jan. 12, 1998 Sec. 102(e) Date Jan. 12, 1998 PCT Filed Feb. 27, 1997 PCT Pub. No. WO97/32161 PCT Pub. Date Sep. 4, 1997According to the present invention, boiler water is pressurized so that its boiling point is set at approximately 200 DEG C. to 320 DEG C. The boiler water is heated in at least two stages. Thermal energy of gases containing chlorine compounds is used to heat the water to its boiling point. Thermal energy of gases which do not contain chlorine compounds is used to heat the water from its boiling point until superheated steam of a given temperature is generated. The heating which uses the thermal energy of gases containing chlorine compounds is accomplished using the thermal energy from the combustion of pyrolysis gases obtained from a pyrolysis means in which waste material is supplied into a chamber containing a fluidized bed medium which has been heated to at least 300 DEG C., and a pyrolytic reaction is induced. The heating which uses the thermal energy of gases which do not contain chlorine compounds is accomplished using the thermal energy obtained from a char combustion means to combust char in which a char mixture consisting of unpyrolyzed residue and fluidized bed medium removed from the pyrolysis means is fluidized by a stream of air, and the unpyrolyzed residue is combusted.
