  • Patent number: 7217245
    Abstract: The systems, methods and apparatus of the present invention comprise noninvasive methods of measuring temperature changes and rates of temperature change in selected body tissues and fluids as a result of absorption and/or dissipation of externally applied heat for the purpose of detecting and monitoring disease or dysfunction, and for preparing diagnostic images of the tissues and related areas from such measurements. Some embodiments of the present invention monitor temperatures of heated tissues directly while other embodiments may measure temperatures of tissues which are heated through flow of heated fluid therethrough.

  • Patent number: 6643543
    Abstract: A body water amount condition judging apparatus is provided wherein at least two values selected from intra-cellular water resistance, extra-cellular water resistance, a combined resistance of the intracellular and extra-cellular water resistance, and the ratio of intra-cellular and extra-cellular water are used as the judging parameters, which values are obtained based on the bioelectric impedance measured in multi-frequency bioelectric impedance measurement. Using these parameters, it is possible to judge the body water amount condition considering not only total body water amount condition, but each constituent component of body water as well.

  • Patent number: 6551256
    Abstract: A snore sensor incorporating a piezoelectric polyvinylidene fluoride (PVDF) film material adapted to be adhered to the skin of a sleeping patient on the patient's throat for detecting mechanical vibrations due to snoring. The PVDF film has a layer of metallization on opposed major surfaces thereof which are insulated from one another by the PVDF material itself and elongated electrical leads individually connect to the metallization layers. One major surface of the film layer is covered by a layer of adhesive tape and the opposite major surface with its metallization is underlayed by a thin layer of plastic film having an adhesive on opposed surfaces thereof. The adhesive on one side of the plastic film layer adheres it to the PVDF film while the adhesive on the opposed major surface of the plastic film is used to adhere the device to the patient's skin.

  • Patent number: 4702246
    Abstract: Pliers are disclosed for the treatment of ingrowing nails on the human body. The pliers comprise first and second jaws. The upper jaw has a support member on which there is mounted an electrical heating wire. A slot in the lower jaw is adapted to receive the support member and wire.In use, the pliers grip are ingrowing toe nail, and an electric heating current is applied to the wire, to cause local heating of the nail. The nail thus softens, and can be bent back into better shape, which shape is retained upon subsequent cooling of the nail. The lower jaw is of a relatively great heat mass, so as to ensure that no undue heating of the nail plate occurs. Control circuitry is provided for controlling the heating current through the heating wire, optionally in dependence upon a detected temperature.

  • Patent number: 4693244
    Abstract: A medical and surgical laser probe comprised of a quartz optical fiber and a laser rod member optically connected thereto which is made of an artificial saphire and has a tapered portion so as to emit the incident laser beam from the tip end of the rod member without leaking it out from the tapered face. With this laser probe, laser irradiation in contact with the tissue is enabled and any desired medical and surgical treatment such as incision, coagulation, hemostasis can be attained effectively.

  • Patent number: 4690130
    Abstract: Chemotherapy may be selectively localized to a tumor located at a point well within the human body by physically associating the chemotherapy agent with magnetic material having a Curie point temperature slightly above the normal temperature of the human body. Both materials may be associated with protein microspheres such as human serum albumin. By applying a magnetic field to the tumor location and then applying electromagnetic radiation to heat the Curie point magnetic material (so that it loses its magnetic properties), away from the tumor site, but not at the tumor site, the unheated magnetic material and the physically associated chemotherapy agent will be localized at the tumor. Radioactive material may also be employed to facilitate imaging of the concentration of the microspheres and for radiation treatment.

  • Patent number: 4608980
    Abstract: A laser hand piece comprises a shank on which is attached the light emitting end of a laser transmission means, a head having a laser light reflecting means and a laser light converging means and a head attachment means for releasably attaching the head to the leading end of the shank. A suitable head is selected from the group comprising heads having an optical means of a different focal length, heads provided with optical means for emitting the laser light in different directions and heads provided with a water supply means and/or air supply means. Therefore, depending upon an affected or diseased part of a body to be treated or operated, a suitable head can be selected and releasably attached to the shank by an operator.

  • Patent number: 4567882
    Abstract: An improvement in catheters and other medical tubes and in the method of use thereof, which facilitates the precise positioning of the tips of such tubes within body passages. The improved method and device are particularly useful in the care and treatment of premature infants. The medical tube has a fiberoptic light conductor extending lengthwise through the wall thereof, the conductor ending in a light emitting and redirecting terminus adjacent the tube's free or distal end. The opposite end of the conductor is operatively connected to an external source of high-intensity light in the visible range. Light emitted laterally from the tip of such an indwelling tube may be visually and externally observed through the body wall of the patient for accurately and quickly determining the anatomical location of that tip.

  • Patent number: 4466446
    Abstract: This invention relates to an improved plunger subassembly for use in a blood gas syringe barrel characterized by a pushrod having a piston on its front end with a hollow interior defining a fluid collection chamber communicating with both the front and rear ends thereof by passageways blocked by a filter that will pass gases but is impervious to fluids. With the plunger subassembly in its passive state, blood and gas entering the syringe barrel from the front is free to enter the collection chamber by means of slits on the periphery of the piston at its front end. The contaminated blood that has been in contact with the air originally in the syringe barrel is trapped in the fluid collection chamber inside the piston while the gases pass on through the filter and are vented to the atmosphere. Opposed surfaces on the pushrod and piston cooperate to define an air-tight seal effective to prevent the flow of air past the piston when the plunger subassemlby is actuated to retract same.
