UWI-E debridement machine is an ultrasound device for wounds treatment, which generates 40Khz ultrasonic wave power and magnifies it through a transducer. The power is carried via the handle piece probe, and conducted to human tissue & work on the wounds through medical normal saline. The purpose is to fast remove the necrotic tissue, bacterium, debirs, fibrin slough, etc. from the wounds, and keep wounds surface fresh to promote wounds healing.

KEY FEATURES

1. EEEICIENT DEBRIDEMENT
The device removes particulate pollution, activated carbon and bacterial contamination. Hospital clinical therapeutic obvious effect reaches 86%, and wounds surface healing reaches more than 80%.
2. LOW FREQUENCY ULTRASOUND
Low frequency of 40-50Khz comes with very weak penetrability of about 1mm at most, which is not provided with complete penetrability to contaminated, infected and decayed tissue. The removal of abnormal tissues and debridement accomplished by probes moves back and forth on the wounds surface. There is no any damage to the normal tissue.
3. FOUR TYPES OF ULTRASONIC TRANSDUCER PROBES
4 kinds of probe shapes designed for different wounds, targeted to achieve better effects. Hand pieces are resuable, able to sterilized and easy to clean and maintain.
4. EASY OPERATION
Human-computer interface simplifies the operation. It doesn't need  special experts and complicated training.
5. LIGHTWEIGHT AND PORTABLE DESIGN
4.5kg lightweight and portable design enables it easy transported to a variety of clinical settings, such as community sites, clinic or at home, between ward units, and even field hospital. Easier carriage and wider applicability.
6. SMALL HANDPIECE
The handle transducer weighs about 400g, and long about 200mm. The lightweight and small size enable the operation easy and flexible, which saves the workload of medical staff, and shorten the time of wounds treatment.

ADVANTAGES

1. PAINLESS DEBRIDEMENT
The low working frequency of ultrasound does no damage to surrounding nurves and blood vessels, and to the normal tissue & new granulation tissue. But it can remove the fibrous protein and necrotic tissue of chronic infection wounds without much trauma, which free the patients from the pain of traditional debridement methods.  
2. PROMOTE WOUNDS HEALING
• It can activate the fibroblasts protease, promote the formation of fibrin layer, and improve the wound surroundings
• Return of the wound to an acute stage thereby promoting granulation
• Existing granulation tissue is preserved
• Necrotic tissue is detached and flushed out
3. THOROUGH DEBRIDEMENT
Which can be achieved by adjusting the distance between the probe and the wound according to the depth of wounds, and applicating in wound areas that ordinary debridement couldn't access e.g. fistula tracts.
4. HIGH RATE OF BACTERIUM REMOVAL
Ultrasound removes bacterium, fungus, and virus of the wounds surface and deep wounds, which reaches up to more than 96%.
5. HIGH SPEED DEBRIDEMENT
The ultrasound wave spray from the handpiece probe, features in large area, even strength, fast speed and short time-consuming.
6. CLOTING EFFECT
With the action of ultrasonic wave, biological tissue dehydrated and generates oxygen, and evaporates, which leads to the capillaries shrinkage, at last effects in stopping bleeding. The in time hemostasis duration debridement provides maximum protection for the patients.
