SAFETY SUMMARY
WARNINGS
The Matrx by Parker DIGITAL MDM® mixer is a specialized medical device and should be operated ONLY by a
professional trained in the use of nitrous oxide. Nitrous oxide and oxygen mixtures should only be administered by
or under the supervision of a medical professional.
The Matrx by Parker DIGITAL MDM mixer is designed for use with an oxygen supply assuring 100% medical
oxygen concentration. The use of other oxygen sources (i.e., oxygen concentrators) could result in an unsafe
condition to the patient.
Although this analgesia machine is designed to prevent the interchanging of the two gases, it is the responsibility
of the user to determine that only oxygen flows into the oxygen connection and only nitrous oxide flows into the
nitrous oxide connection located on the back of the analgesia head.
ELECTRICAL CONNECTIONS & GROUNDING INSTRUCTIONS
The unit must be grounded. If it should malfunction or breakdown, grounding provides a path of
least resistance for electrical current to reduce the risk of electric shock.
A known Protective Earth (ground) connection must be made via one of the following methods:
1) The third wire on the power cord when plugged into an appropriate outlet that is properly
installed and grounded in accordance with all local codes or ordinances.
2) The external ground lug on the rear of the device.
A Protective Earth (ground) connection is a connection attached to the facility grounding point
outside the facility. A licensed electrical person should be consulted to confirm the Protective
Earth (ground) connection.
Do not use an electrical cord with nicks, cuts, or other damage. Do not use the unit with an
extension cord as it will be subject to electromagnetic interference (EMI).
BAG TEE REQUIREMENTS
A bag tee containing an air inlet valve is required for use with this unit. The bag tee is factory
mounted on the unit or provided separately for remote mounting. Matrx by Parker Scavenging
Nasal Inhalers provide the patient connection.
CAUTIONS
FACTORY SETTINGS
Do not change any internal factory set adjustments. The Matrx DIGITAL MDM mixer is adjusted and calibrated for
proper operation prior to shipment. Any change could alter the specified operation and accuracy.
FACILITY PIPING
The user MUST perform tests independent of the dealer or contractor to verify that all pipelines are connected
correctly. If you are unfamiliar with piping systems, order Matrx manual 10311700. The user has the ultimate
responsibility for properly connected pipelines essential to patient safety.
DIAMETER INDEXED SAFETY SYSTEM
Gas connections in the DIGITAL MDM mixer are mechanically indexed using the Diameter Indexed Safety
System (DISS). This feature helps to prevent the crossing of pipelines. Under no circumstances should these
connections be altered.
DISCONNECT POWER
There are no user-serviceable parts inside this unit. A shock hazard exists if power is not
disconnected prior to any internal servicing or maintenance. Always disconnect the power
source before inspection or repair.
ALARM TEST
The user should test the alarm system for proper operation prior to each clinical use.
