Publication number: 20010038003Abstract: A paraffin bath apparatus for melting paraffin used in therapeutic applications is disclosed. The paraffin bath apparatus comprises a housing having a base, a sidewall and upper opening. An inner tub is formed of a temperature resistant polymeric material is a generally cup shaped member having a bottom wall, an upstanding wall and an open top. The inner tub is received within the upper opening of the housing with the bottom wall of the inner tub overlying the base of the housing. The heating element is located between the inner tub and the housing for providing heat to the inner tub sufficient to melt the paraffin but below the temperature that would adversely affect the polymeric material forming inner tub. A thermostatic sensor is disposed between the inner tub and the housing and is electrically connected to the heating element to control the heat provided to the inner tub. A temperature indicating element may be provided in the inner tub and placed in contact with paraffin melted in the inner tub.Type: ApplicationFiled: June 26, 2001Publication date: November 8, 2001Applicant: HoMedics, Inc.Inventor: Dov Glucksman

Patent number: 6255627Abstract: A thermal treatment system warming basin for warming a sterile liquid or medium includes a heating pad disposed on the exterior surface of the basin floor in various configurations (e.g., spiral, ‘I’, ‘X’ or serpentine configurations, multiple heating pad segments disposed about the basin floor, etc.) to prevent damage to a sterile surgical drape placed over the system when objects are placed within the basin. The configurations cover a portion of the basin floor to permit the basin to absorb thermal energy that may otherwise be absorbed by and cause damage to the drape. In addition, a thermal treatment system and corresponding sterile surgical drape may include a variety of mechanisms to ensure sterility of a sterile liquid within a basin. In particular, the drape may include a reflective material segment to reflect infrared light emitted from an infrared light source toward a detector to indicate the proper positioning and/or presence of the drape on the thermal treatment system.Type: GrantFiled: June 27, 2000Date of Patent: July 3, 2001Assignee: O.R. Solutions, INc.Inventors: Durward I. Faries, Jr., Bruce R. Heymann, Calvin Blankenship
