Abstract
An apparatus and method for a ventilation mask. The ventilation mask includes an upper hood and a toroidal tube. The toroidal tube is made of soft silicone, and a tube shape is first formed when the middle part of the tube shape is formed into an 'S' shape, and whenever the lower part of the 'S' is turned upwardly and inwardly, the 'S' part will form the toroidal tube. Air can be injected into the toroidal tube so as to conform the face of the patient. An assembly member is used to assemble the upper hood and the toroidal tube. The advantages of the ventilation mask include added comfort, excellent air tightness, transparency. The toroidal tube can be disassembled to be disinfected for repeated use or for replacement. The upper hood does not have to be replaced.
