Affordable Cavitational Ultrasound Heals Chronic Wounds

February 11 - The Qoustic Wound Therapy System, low-frequency cavitational ultrasound designed as an affordable alternative to sharps debridement and other surgical modalities, was released today by Arobella Medical LLC.

The Qoustic Wound Therapy System was designed to remove dead or diseased tissue cells and bacteria, leaving healthy and pre-healing granulation tissue intact. It was also designed to prepare the wound bed for other therapies, such as grafts and flaps.

Low-frequency ultrasound debridement is an emerging method of care for many types of wounds, including pressure ulcers, diabetic ulcers, infected wounds, burns and other chronic wounds, according to the company. Five to seven million people each year in the U.S. require treatment for chronic wounds resulting from ulcers, sores, burns, fistulas and other conditions. A significant number of the people with chronic wounds have diabetes, and rapid growth of the diabetic population is increasing the need for advanced wound care.

The Qoustic Wound Therapy System reportedly removes harmful bacteria and biofilm and improves wound bed circulation. The system’s dome-shaped Qoustic Qurette vibrates at 35 kHz, converting electrical energy to ultrasound waves and focusing them on the wound. Sterile saline solution transfers the ultrasonic energy to the wound, where tiny vibrating gas bubbles and cellular-level fluid movement separate dead and harmful cells from healthy tissue. As a result, dead and harmful cells are fragmented and destroyed, thus aiding in their removal with the edge of the Qoustic Qurette, said the company.

The Qoustic Wound Therapy System is portable and is made to be used in many health care settings - including the bedside - by certified wound care specialists, including physicians, registered nurses, nurse practitioners, physician assistants, physical therapists and podiatrists. The system has FDA 510(k) clearance.
