Abstract:
An apparatus for calibrating at least one pressure-sensing catheter, said catheter having at least one transducer supported on a first end for detecting blood pressure pulses, comprising:(a) a vessel having an opening for introducing a fluid into said vessel, said fluid defining a horizontal fluid level line within said vessel;(b) a removable closure means for said opening;(c) at least one catheter port corresponding to each said catheter, said catheter port defined through said closure means through which said transducer on said first end of said corresponding catheter may be introduced into said fluid in said vessel;(d) means for providing an airtight seal between said catheter and said corresponding catheter port;(e) a pressure port defined through said closure means through which at least one known pressure may be introduced on said transducer;(f) means for introducing said known pressure through said pressure port on said transducer; and(g) means for measuring the hydrostatic pressure exerted upon said transducer by said fluid.
