Parker Nitronox Scavenger FM-1330 Repair

The Medical Breathing Circuit Scavenger System (with Porter Medical Breathing Circuit) is used to deliver a gas mixture to a conscious, alert patient who requires relief from minimal to moderate pain during medical procedures. This system is intended for use by medical professionals trained in use of nitrous oxide and oxygen for medical applications. The Parker Nitronox Scavenger helps maintain the safety of the clinicians and patients during procedures requiring analgesic sedation.

The Medical Breathing Circuit Scavenger System is intended for use in hospitals, clinics, and emergency care settings. This system is appropriate for use during labor and delivery, radiology, oncology, burn units, urology, and medical aesthetics. Request more information about using this system through the official Parker Porter Instrument website.

This model (FM-1330) is designed for use with Nitronox HD Inhalation Analgesia System (refer to FM-1308 instructions) or an Analgesia Conscious Sedation Flowmeter. This Scavenger System removes O2/N2O gas mixtures exhaled by patients during analgesic sedation. Exhaled gases are routed through the Interface to the vacuum system. The Scavenger and vacuum systems dilute and dispose of waste gases.

The medical establishment and acting medical professional must develop specific delivery protocols. The upper limit of the number of hours of transient delivery is at the determination of the medical professional. The acting medical professional will turn on and observe the operating indicators of the device.

The Parker Nitronox Scavenging System (FM-1330) has a box-like appearance with two attached hoses. One of the hoses attaches to the top of the box via a foam resistor. The front of the box features two pressure gauges. The construction materials are plastics: ABS, PVC, polyethylene, and nylon.

To find the model number for your Scavenger System, look for the identification plate on the main unit's housing or cylinder stand. Be mindful that the model number is different from the serial number.

1. Gas flow path starts with patient exhalation from mask into the coaxial tubing of the disposal Medical Breathing Circuit and then to the tee through the one-way valve into the 19 mm scavenger hose.
2. The scavenger hose leads the gas into the Scavenger Interface via a foam resistor at the top.
3. Gas passes through the Interface to the vacuum via a ball-type control valve to a calibrated orifice within the barbed vacuum connector.
4. Finally, the gas passes through the vacuum hose to vacuum outlet.
