The compact and intuitive AG Cuffill device is an accurate solution for measuring cuff pressure and controlling the volume of air in the cuff of the ET Tube. Its pocket-size and syringe-like design allows a simple and easy operation by vets, nurses and technicians. The operation of the device is the closest to the existing common practice, i.e., filling the cuff with a syringe. The Cuffill is designed and manufactured for 100 measurements and should be discarded when not usable.
