Which EMC (electromagnetic compatibility) devices are helpful for the design and modification of enteral nutrition pumps?

The EMC design of enteral nutrition pumps shares similarities with that of infusion pumps. The drive circuit of the pump motor (whether a DC motor or a stepper motor) requires proper decoupling and filtering. If the motor casing is metallized, it should be grounded. Signal lines from pressure sensors or photoelectric sensors used to detect tubing blockages should be shielded, and the signal should be low-pass filtered before entering the control board. If the device has wireless capabilities (e.g., Bluetooth data transmission), its antenna should be kept away from the motor and power supply; a ferrite bead can be added to the antenna feed line. For the FPC cabling of the user control panel (especially the touchscreen), conductive cloth can be applied or a common-mode filter can be added to suppress radiated emissions.
