No, you didn't go into the website far enough. They make hundreds of products. There is an extensive written overview of the proposed use and proof of concept clinical trials of a Healight UV catheter to kill bacteria and virus in intubated patients. The main stream media won't say it, but medical professionals have observed that most intubated COVID-19 patients are dying faster than those not intubated. The thought is that intubation makes the body conditions more favorable for rapid, uncontrollable growth of the virus and related pneumonia bacteria. There has been a huge move to the use of positive pressure breathing machines (CPAP) and far lower mortality in those receiving that form of respiratory assistance. Since certain people with high political profiles have screamed for more respirators the main stream press has no desire to expose their ignorance. Intubation is a horribly invasive procedure, and has been cited as a major cause of infection in physicians, as the patient will always involuntarily struggle and large amounts of sputum hit the physician in the most vulnerable area for infection, the face. Those huge doses of virus have been fatal, and the practice is discouraged. It's all on the website.
