Specification :

Uses: treatment of various types of trauma, surgical wounds, infected wounds / wound, such as burn wounds, purulent wound / wound, sinus, fistula; difficult to heal wounds, such as diabetes, wounds, pressure ulcers, neurotrophic ulcers, traumatic ulcers, etc.; soft tissue trauma, open fracture, etc.

PATENT TECHNOLOGY

* XN-HW Ultrasonic Wound Debrider designed independence possess China sciential property right invention patent ZL011084596 and New pattern utility patent ZL042328484.

Mechanism of Treatment

* Ultrasonic cleaning incision of pig muscle in vitro -carbon removal 83.8% -93.6%
Simply rinse -31.2% -40.0%

Mechanism of Treatment

* Ultrasonic power of low frequency of the device is transmitted to tissue via vibration of the hollow titanium tip of the hand piece, which creats cavitation, micro-jet and mechanical vibration in water jet, puffed from the hollow tip of the titanium staff of hand piece.The necrotic matter, infected cells, fibrin slough, and biofilms while leaving intact healthy tissue structures are removed by ultrasonic power.Because the tensile stength of necrotic tissue has considerably less, it is easily removed by ultrasonic power of low frequency of the device.

New Concept, Special technology, High Quality, Human Engineering Design

XN-HW ultrasonic wound debrider, based on new concept of ultrasonic and computer technology, is a novel device for treatment of contaminated and infected wound.It can destruct and flush out bacteria, viruses, fungs and necrotic tissue in wound, and prompt wound healing by special low frequency ultrasonic power loading water jet, which initiates cavitation, micro water jet and mechanical effects.Patients received this treatment do not sense pain.

This device applies human engineering design and unique steady-frequency technique, so every hand piece if it' s working is in the best operation state every time.

Clinical application:

* Removal contamination all manner of soft tissue injury, mechanical injury or chemical, such as knife injury, firearm injury, fireburn, chemical burn and warfare-agent injury so on.

* Treatment of infection all manner of acute infective wound or raw-surface, and chronic infective wound, such as diabetes-foot, neurotrophic ulcer, bedsore and surgical-operation infection so on.

The outstanding effects of the debridement

* To destroy and scavenge bacterium in superficial and deep layer tissue, the rate of scavenging bacterium can reach to more than 95%

* To scavenging fibrin and necrotic tissue in chronic infective wound painlessly

* To avoid damaging normal tissue, to preserve and promote growth of granulation tissue

* To stimulate lysomal enzyme activity and to increase protein activity in fibroblast, toevoke mast cell to release pro-inflammatory cytokines and growth factors

* To promote antibiotic in rinse solution into deeper tissue

Lower cost

* The rinse solution is normal saline, about 30-50ml/ min

* Using the special technology of scanning and steady ultrasonic frequency, the device can matcn anyutrasonic hand pieces of the ultrasonic debrider.
