Apparatus and methods for the treatment of avian influenza with ultrasound

The method and device of the present invention for the treatment of avian influenza and other viruses, bacteria, and infectious agents with ultrasonic waves includes a generator and a transducer to produce ultrasonic waves. The ultrasonic transducer has a specially designed ultrasound tip that is able to radiate ultrasound energy toward the body of the target animal or human at a level higher than a traditional ultrasound tip. The apparatus delivers ultrasonic energy without contacting the target through an air / gas medium or through a spray, or by contacting the target with or without a coupling medium. The ultrasonic waves provide a therapeutic effect such as destroying viruses, bacteria, or other infectious agents, increasing blood flow, or stimulating the immune system, etc; additionally, breathing ability is enhanced through the ultrasonic delivery of a medicament to the target's lungs.

Methods and apparatus for adjusting blood circulation

Embodiments of the invention include a method and a device for increasing blood flow and controlling the temperature of a mammal by applying a desired pressure to extremities of a mammal. The device generally includes one or more collapsible and pliant body elements, capable of expanding from a first volume into an expanded second volume so the device can receive a portion of an extremity of the mammal therein and then be reduced from the expanded second volume into a pressurized third volume to conformably enclose the portion of the extremity. One or more thermal exchange units can be positioned in the one or more collapsible and pliant body elements. Accordingly, the temperature of the extremity of a mammal can be regulated by providing a heated or cooled fluid medium or electric thermal energy to the one or more thermal exchange units. Next, by evacuating the region in which the extremity is enclosed the contact surface area between the extremity of a mammal and the one or more thermal exchange units is increased, due to the external atmospheric pressure acting on the pliant body elements against the skin of the extremity of the mammal. The application of pressure assures that sufficient contact and thermal heat transfer (heating or cooling) is provided to the extremity of the mammal.
