Which EMC (electromagnetic compatibility) devices are helpful for the design and modification of hemodynamic monitoring devices?

The core of this device's EMC protection lies in protecting the sensor interface and signal chain. The analog output signal line of the arterial pressure sensor must use high-quality shielded cable, with the shield grounded at a single point on the device side. After entering the instrument, the signal first passes through a radio frequency interference (RFI) filter (typically an RC or LC network) before entering a high-impedance instrumentation amplifier. The constant current source circuit powering the sensor needs to be exceptionally stable, and its power supply must be well-filtered. The interface for communication between the device and external modules (e.g., a thermal dilution injector) (e.g., RS-232) should use an isolated interface chip and be configured with ESD/TVS protection (e.g., SMBJ18CA). The entire device uses a metal casing and is grounded.
