1. A portable ultrasound device for treating wounds, comprising:
- a. A power supply;
b. A generator electrically connected to said power supply;
c. An ultrasound transducer containing a distal end, electrically connected to said generator;
d. An ultrasound tip attached to the distal end of said ultrasound transducer comprising;
i. A proximal concentrator portion, having a longitudinal axis, in contact with said transducer, said concentrator portion tapering toward a smallest cross section at it'"'"'s distal end;
ii. A distal end radiation portion oriented substantially perpendicular to said longitudinal axis of said concentrator portion containing a peripheral boundary, said distal end radiation portion projecting radially from the distal end of said concentrator portion, with a maximum diameter approximately 2 times or greater than the diameter of said smallest cross section of said concentrator portion; and
e. A fluid supply capable of delivering a fluid to the radiation portion.

Abstract
Device and methods for the treatment of wounds using ultrasound energy are disclosed. The portable wound treatment device may deliver ultrasound energy to a wound through direct contact with the ultrasound tip and/or through a liquid coupling medium. Several ultrasound tips specially designed to concentrate and focus ultrasound energy onto a wound are also disclosed. The ultrasound tip may also possess an abrasive peripheral boundary to aid in debriding the wound and/or removing necrotic tissue. The disclosed invention may have multiple beneficial effects in treating a wound such as sterilizing a wound, reducing external bleeding, and/or providing pain relief.
