ABSTRACT:
A vacuum flow measurement device measures the quantity of air flowing into a high-volume evacuator (HVE) vacuum tip commonly found in dental treatment rooms. The device includes a tubular member constructed to mimic internal structural characteristics of a HVE tip. The tubular member includes a valve end coupleable with a HVE valve and an open end. A pressure gauge is connected to the tubular member via a port spaced from the open end of the tubular member. When the vacuum flow measurement device is coupled with the HVE valve, an air flow rate is determined as a function of pressure measured via the pressure gauge.
