Oxyll selector

Oxyll®ball flowmeters are recommended  for use in oxygen therapy, are lightweight, easy to use, effective and accurate. Flowmeters compensate the variations of pressure of the pipeline since they admit all the pressure in the line, maintain the pressure and supply the patient with the selected flow at atmospheric pressure through the mask, nasal catheter, nebulizer, humidifier, etc…

They have been designed for time and oxygen saving. Via a revolving control knob, oxygen is supplied through a direct outlet to either a face mask, a nebulizer or a humidifier, during which, oxygen is not being interrupted.
