The Equinox Advantage Nitrous Oxide/Oxygen Analgesic Gas Mixing and Delivery System is a portable pneumatically powered device intended to administer an adjustable mixture of Nitrous Oxide analgesic gas and Oxygen to provide pain relief, on demand, to a conscious, spontaneously breathing, patient. The device provides two input connectors for connection with nitrous oxide and oxygen cylinders through pressure regulators. The device has a control knob for turning ON or OFF the device. When it is turned ON, the output of N2O/O2 gas mixture will only be administered by an inspiratory effort by the patient. The output ratio adjustable knob controls the percentage of the out analgesic gas mixture. The adjustable range is from 25% O2 (N2O 75%) to 100% O2 (N2O 0%). The minimum of 25% oxygen output eliminates delivering a hypoxic mixture.The oxygen enrichment button allows 100% oxygen supply in case of emergency.
A device primarily designed to administer analgesic gases to the patient, or produce analgesic vapours for inhalation. The unit will typically include a demand valve; some may be connected to a vaporizer calibrated for the administration of analgesic concentrations of inhalational anaesthetic agents. Typically used: 1) during labour to help the patient retain her consciousness while pain sensations are subdued; or 2) in dentistry.
