Description
I am working on a new device that would restrict breathing.

An air inflated balloon gag is placed in the oral cavity. Compressed air is injected through a solenoid valve. As a result, the balloon gag is inflated in the oral cavity.

An air inflatable plug is also inserted into the nasal cavity. Compressed air is injected through a solenoid valve.

Breathing is thus completely restricted. Exhalation is done through a breathing tube that passes through the center of the balloon gag. Here, too, a solenoid valve is provided for complete control of respiration.
