Abstract
An electronically controlled syringe system for connection to a balloon catheter for automatically monitoring, displaying and recording inflation or deflation data. A syringe applies and releases pressure to and from the balloon catheter. A transducer housed on the syringe barrel emits at atmospheric pressure a signal by which both the syringe and transducer are recognizable to the system as a particular type of syringe. The system prompts the user to verify the recognized type of syringe. The system prompts the user to verify the recognized type of syringe. The transducer, which can be calibrated, senses fluid pressures applied by the syringe. The signal output by the transducer is input to a controller where the signal is digitally processed so as to derive and record therefrom data representing the magnitude of applied fluid pressure and the length of time that pressure is applied by the syringe. The data is automatically displayed and recorded. The syringe system permits input of various control parameters, such as a maximum positive inflation pressure and maximum duration for applying pressure.
