The research is designed to evaluate the effectiveness of the application of the pulsed xenon ultraviolet (PX-UV) disinfection device in reducing the Healthcare-associated infections (HAIs) and the recovery of healthcare-associated pathogens.


The PX-UV device reduced recovery of MRSA, C. difficile, and VRE on glass carriers and on frequently touched surfaces in hospital rooms with a 10-minute UV exposure time.

Disinfection distance will affect the effectiveness of the disinfection. The PX-UV device also has some potential limitations. The efficacy of PX-UV was dramatically reduced as the distance from the device was increased. Therefore, it is recommended that commonly touched surfaces (eg, bedside table, call button, telephone) be arranged close to the device for optimal exposure to irradiation.

To solve this issue, we have developed a comprehensive disinfection system that may help, the Pulsed Xenon UV Disinfection chamber (PX-UV chamber) will be used for the disinfection of most reused medical instruments, which is powered by a high-intensity Pulsed Xenon UV disinfection robot or PX-UV robot. Besides, we have other equipment for whole room disinfection, such as Upper-Room Ultraviolet Germicidal Air Disinfection and Portable UV Ultrasound probe sterilizer and other UV area sanitizer and UVD robot. All these will help to reduce the HAIs and can generate great revenues.

The research also compares the effectiveness of Pulsed Xenon Versus Continuous Mercury UV for Killing of Pathogens.

Other discussions provided:

The PX-UV device has some important potential advantages over other UV disinfection devices. First, unlike continuous UV-C devices, xenon flash lamps do not contain mercury. Therefore, there are no safety hazards associated with disposal or exposure to mercury. Second, the manufacturer recommends a relatively brief disinfection cycle (10–20 minutes per room versus up to 45 minutes for spore-killing cycles of some UV-C devices) which may facilitate greater use of the devices.
