MX960 REUSABLE PRESSURE TRANSDUCER
The MX960 reusable pressure transducer is used to convert hemodynamic pressure waveforms via a piezoresistive bridge circuit into electrical signals which can then be displayed using separate monitoring equipment.
The MX960 reusable pressure transducer is a non-fluid pathway device. A pressure waveform is conveyed through a disposable dome which is coupled to the reusable pressure transducer during pressure monitoring. Both the transducer and dome have mutually exclusive diaphragms. Accordingly, fluid contact is limited to the dome portion of the system. The materials which comprise the MX960 have been aggressively tested per the ANSVAAMI/ISO 10993 "Biological Evaluation of Medical Devices" and the "Tripartite Biocompatibility Guidance for Medical Devices". All materials have successfully met these standards.
The Medex, Inc. MX960 Reusable Pressure Transducer underwent performance testing against the ANSI/AAMI BP22-1994 standard for blood pressure transducers.
