is a compact, portable, battery powered, solid state electronic audio amplifier:

having special characteristics for sensing the low frequency pressure pulses of the cardiovascular system and the sounds of respiration. Heart/pulse and/or respiration sounds are picked up by a sensor unit from an esophageal stethoscope tube or chest piece cup, amplified and presented audibly from a speaker and visually by a flashing red indicator light. A "beeper" sound function is selected by a mode switch for increased audibility in heart monitoring.



Features :

  • Compact: (4"x 6" x 3 1/2" -- l 1/2 lb.) facilitates placing the unit on an operating table or mounting to wall or to anesthesia machine with accessory brackets for unmatched convenience.

  • Greater sensitivity: enabling use with chest piece cups at weaker signal sites, as well as with esophageal stethoscope tubes.

  • Miniaturized sensor unit: suitable for direct connections to accessory sound sources with less clutter.

  • Mode selector switch: for choosing best audibility characteristics for the type of monitoring desired.

  • Pulselite: flashing red light indicator for visual heart/pulse monitoring.

  • Metal case: seamless, deep-drawn, heavy aluminum case with carrying handle provides complete shielding from pick up of electrical interference from other equipment.
