Abstract
A novel pressure transducer apparatus for medical pressure monitoring apparatus having a housing with a calibration port. The patient side of the transducer senses fluid pressures to be monitored. The non-patient side of the transducer is hermetically sealed in the housing of the apparatus. The housing has a female calibration port communicating, via a pinhole, with the non-patient side of the transducer. The non-patient side of the transducer can thus alternatively be vented to atmospheric pressure or be exposed to a vacuum calibration pressure.
