  • Patent number: 10734835
    Abstract: A power bypass apparatus with a current-sharing function includes at least two bypass switch assemblies and a control unit. Each bypass switch assembly includes a controllable switch, a cooling unit, and a temperature detection unit. Each the temperature detection unit, correspondingly disposed to a heat-dissipating unit, detects a temperature value of the controllable switch to produce a temperature detection signal. The control unit receives the temperature detection signals and outputs at least two switch control signals to control at least one of the controllable switches or outputs at least two cooling unit control signals to control at least one of the cooling units, thus making currents flowing through the controllable switches identical. Accordingly, it is to increase overall efficiency of a power system and implement current-sharing function of the power system providing high power.

  • Patent number: 8475510
    Abstract: Disclosed are embodiments of airflow applicators used for delivering directional, heated air to, for example, the scalp and hair of humans and/or animals to eliminate ectoparasites, such as lice and lice eggs. In preferred embodiments, the applicators are configured to deliver heated airflow (from a separate device, or from another portion of a single device, that generates heated airflow) efficiently right to where ectoparasites and their eggs most frequently reside. Also disclosed are treatment methods, including preferred treatment patterns, for delivering heated airflows for use in eliminating ectoparasites and their eggs on an animal.

  • Publication number: 20130103127
    Abstract: A hand-operated cooling device for cryotherapy for treating pain, inflammations, muscle tensions or the like, includes a main body and a receptacle, which can be inserted at least partially into the main body, for the exchangeable accommodation and insertion of a gas pressure vessel. The main body includes a gas outlet actuation arrangement, which can effect, by manual actuation, the outflow of a gas from the gas pressure vessel when the receptacle is inserted, and the receptacle includes a cooling surface, which can be cooled by the outflowing gas and by the gas pressure vessel jacket, wherein the gas can be conducted inside the main body and inside the receptacle by a gas conducting arrangement and can exit at the receptacle adjacent to the cooling surface.

  • Publication number: 20130103126
    Abstract: The present invention provides a method and device for non-invasive anatomical and systemic cooling. The method and device provide for cooling of various bodily fluid- containing spaces or surfaces, such as mucus-containing spaces or surfaces via delivery of a dry fluid not including a coolant into or upon the mucus-containing space or surface. Exposure of such mucus to the dry fluid results in evaporation and cooling of the anatomical feature and/or systemic cooling, as intended. In this fashion, therapeutic hypothermia may be achieved to provide for neuroprotection of various organs after ischemic insult, such the brain after cardiac arrest.

  • Publication number: 20130041438
    Abstract: A convective thermoregulation blanket (204) includes an exterior surface (220), a plurality of interconnected distribution channels (940, 941) and a first inlet opening (1244). A portion of the exterior surface is configured to be in contact with a patient. The interconnected distribution channels are located internal to the convective thermoregulation blanket and include a primary distribution channel (940) having an interior surface. The first inlet opening extends between the exterior surface of the convective thermoregulation blanket and the interior surface of the primary distribution channel to deliver thermal regulated convective air into the primary distribution channel. At least a portion of the primary distribution channel includes a filter material. The filter material filters unfiltered thermal regulated convective air in the primary distribution channel and provides the remaining plurality of distribution channels with filtered thermal regulated convective air.

  • Patent number: 8372129
    Abstract: A patient warming device includes a gasket coupled to an interior surface of a base film to define a target region that is attachable to a body surface of a patient. The base film extends from a perimeter of the gasket to provide a surgical drape. An evacuation port is in fluid communication with the target region. When attached to the patient, suction applied to the target region via the evacuation port vasodilates the body surface of the patient such that a heat source communicating with the target region increases a core temperature of the patient.

  • Patent number: 8317849
    Abstract: An underbody convective warming blanket that may be used by a pediatric or neonate patient includes a head portion configured with multiple substantially U-shaped channels each having a plurality of adjacent rows of apertures that circumscribe the head of the patient positioned on the blanket. The adjacent rows of apertures are configured on the upper layer of the blanket so as to be positioned at an orientation or angle relative to the base plane of the blanket or the head of the patient such that those apertures would substantially face the head of the patient when the blanket is inflated, so that the heated air output from the apertures is directed substantially towards the head of the patient to thereby effect an invisible dome of heated air that envelopes the head of the patient.

  • Patent number: 8313519
    Abstract: A multifunction warming device includes a clinical garment having an inside surface supporting a convective apparatus disposed to provide therapeutic warming of a patient's upper body during surgery. The warming device includes a clinical garment with an elongate convective apparatus supported on the inside of the garment, transversely to the garment, and running between its sleeves. The positioning of the convective apparatus in the clinical garment locates it against the chest of a patient wearing the garment and permits it to be deployed and used on the patient's upper body during and after surgery without removal of the clinical garment from the patient or removal of the convective apparatus from the clinical garment.

  • Patent number: 8308788
    Abstract: An externally-applied heat exchange pad has three layers laminated together, an inner and outer non-conductive layer and a middle conductive layer. A leak in the inner layer causes coolant to contact the middle layer and change impedance, which can be sensed and used as an indication of an impending total leak of the pad.

  • Patent number: 8308785
    Abstract: A convective warming blanket has a head portion and a plurality of peripheral sections extending orthogonally from each side of a central section that extends uninterrupted from a proximal end below the head portion to a distal foot end of the blanket. Each peripheral section is separable from its adjacent peripheral section by a frangible or tearable common seal. At least one through passage connects each peripheral section to the central section, so that the peripheral sections are inflated when heated air is input to the blanket. The multiple peripheral sections each are movable relative to the central section, so that different body parts of the patient may be selectively accessed. The head portion of the blanket is formed by two tubular sections that extend from the proximal portion of the blanket to encircle the head of the patient, when the blanket is placed over the patient.
