A mechanical system that imitates projectile vomiting.
Researchers in North Carolina use the barfing machine to study how human noroviruses, leading causes of upchucking worldwide, spread through the air.
The vomiting device’s tubes, valves, piston and pump imitate a human mouth, throat and stomach at one-quarter size. A clay face mask gives the machine an appropriate expression of misery, but it also provides weight to bend the throat down, simulating the flexed neck of a heaving human.
