Common solutions for common problems. Observations.
Device type: Continuous Monitoring [EKG], Make: Philips, Model: MX40
Problem: Device boots up, but does not transmit telemetry to 'central'.
Cause 1: Wet cleaning prior to lead set plug-in mobilizes gold coating during powered state. Corrosion on PIN4.
Solution 1: Using a burnishing tool or similarly hard plastic pick, remove gray-green surface. Remaining usefulness depends on preserving remaining pin height.
Simulate @ 60 BPM and evaluate signal integrity to confirm success.
Cause 2: Wet cleaning prior to lead set plug-in mobilizes gold coating during powered state. Corrosion on PLUG4.
Solution 2: Using a burnishing tool or similarly hard plastic pick, remove gray-green surface. Remaining usefulness depends on preserving remaining plug spring tension.
Material appendices: The rear plastic battery tray cover is comprised of Polysulfone (or PSU).
Exercise left to the reader: How would you design a lead set that has high conductivity, flexibility, and does not corrode in the presence of salts?
Device type: Diagnostic [EKG], Make: Philips, Model: TC50
P1: Device does not boot.
C1: Device side of power cord has backed out.
S1: Secure proximal cable. Simulate flexion. Replace with medical grade (marked with green dot) if back-out reoccurs.
