BALLOON INFLATION DEVICE

摘要

A balloon inflation device is provided for inflating a balloon having a neck. The balloon inflation device includes: a source of pressurized gas; an inflation nozzle selectively receiving the neck of the balloon to communicate with the interior thereof, the inflation nozzle including: a fill nozzle having an outlet end, and a pressure sensor nozzle inside of the fill nozzle, the pressure sensor nozzle having an inlet end. The outlet end and the inlet end communicate with the interior of the balloon when the inflation nozzle receives the neck of the balloon. A gas feed line communicates between the source of pressurized gas and the fill nozzle of the inflation nozzle, and a pressure sensor communicates with the pressure sensor nozzle such that the pressure sensor is affected by the pressure of the gas within the balloon as received at the inlet end of the strain gauge nozzle.
