Hi Oxygen Mask

Features

Simple design with an oxygen mask and an oxygen reservoir bag.
One one-way valve is placed between the mask and the reservoir to prevent exhaled air from entering the reservoir bag.
One or two one-way valves may be placed on the mask to maintain high oxygen concentration in the mask.
Continuous oxygen flow in the reservoir bag will maintain at least 1/2 or 1/3 oxygen supply in the bag during respiration.
Light-weight reservoir bag provides higher efficiency and patient comfort. Aluminum nose clip allows adjustment for stability and patient’s comfort.
Single-patient use to minimize cross contamination.
Latex-free elastic head strap to minimize skin irritation.

Package: 1 package/set, 50 sets/box.
