We’re proud to announce that Wei Nasal Jet (WNJ) Tube was successfully launched in the annual meeting of American Society of Anesthesiologists (ASA), in October, 2023 in San Francisco, USA. WNJ has been highly praised and widely received by worldwide anesthesiologists.
Wei Nasal Jet Tube, an innovative device for performing Supraglottic Jet Oxygenation and Ventilation (SJOV), has 2 channels in the tube wall to provide supraglottic Jet pulse oxygen and monitor PetCO2 respectively. Multiple multicenter randomized clinical trials (RCT) have confirmed WNJ is highly effective to prevent hypoxia in patients receiving procedures of upper gastrointestinal or uterus endoscopy under propofol infusion heavy sedation, especially in obese patients, with minimal side effects or complications. Clinical studies also suggest that WNJ is a useful and convenient device to provide oxygenation/ventilation effectively during elective or emergent difficult airway management, with minimal side effects or complications. 
Wei Nasal Jet Tube has been approved by FDA in USA, and registered in Europe, legal to be commercialized in these markets.
