Aequitron Model 9500 / 9550 Repair

Aequitron's Model 9500/9550 is an apnea monitor used to measure respiration and heart rate in one device. This device monitors the rhythm of patients' respiration to prevent apnea caused by anything from throat spasms to cardiac arrest as well as monitoring arrhythmia and other irregular heartbeats. The device is to be used by medical professionals in hospitals.

Being able to monitor patients' irregularities in breathing and heart rhythms allows for medical staff to make swift decisions to allow for optimal patient care and outcomes. With the warning alarm and lights, medical staff can easily determine the cause of a patient's medical distress, assess how to regulate the issue, and provide the necessary care to alleviate the symptoms.

Aequitron, Inc. was acquired by Mallinckrodt in 1989.

The Aequitron Model 9500/9550 has two panels: front and back.

The front panel has red lights for human alarms (apnea, heart fast, heart slow) and yellow lights for equipment alarms (battery, lead, monitor), a reset button, a power switch, a patient cable jack, green lights for breathing effort and heart beat, and an alarm speaker.

The back panel has the serial number, battery charger jack, battery charger light, interface for recording respiration and heart rate, ECG and RESP outputs, remote alarm jack (for optional alarm), controls, and function display.

The device will be white all over and have gray panels on the front and back where the alarm lights, buttons, and switches are located.
