ABSTRACT:
A disposable esophageal probe incorporating the capability to detect ECG waveforms, heart sounds and to measure body core temperature is described. The probe incorporates a plastic tube with electrically conductive pathways embedded in its side walls thereby eliminating any lumen obstruction. Its distal end is enclosed by a rubber sheath which provides a diaphragm for the transmission of sounds into the lumen of the tube. An integral disposable connector assembly is provided at its proximal end to enable direct connection to be made to the plastic pathways and the lumen. A modification of the probe which allows it to monitor respiration rate is also described.
