Air Oxygen Blender – 689-B

Air Oxygen Blender: Compact & Reliable

The Air Oxygen Blender offers a compact and reliable solution for managing oxygen supply in medical settings. Made from high-quality plastic, this device features a user-friendly design. Additionally, it has a reserved oxygen battery interface for monitoring oxygen concentration. You can adjust both the concentration and flow rate separately. Specifically, the oxygen concentration ranges from 21% to 100%, while the gas flow can be set from 0 to 20L.

Key Features

• Flow Meter: First, the blender includes a flow meter that shows the flow rate of the mixed gas. This feature ensures accurate monitoring.
• Flow Regulating Knob: Next, use the flow regulating knob to set the mixed gas output between 2 and 20 LPM. This allows flexibility in oxygen delivery.
• Flow-Variable Mixed Gas Outlet: Furthermore, this outlet provides mixed gas output at a fixed flow rate of 2-20 LPM. This feature accommodates various patient needs.
• Oxygen Concentration Regulating Knob: You can easily adjust the oxygen ratio in the mixed gas from 21% to 100%. This meets specific patient requirements.
• Connectors: The air inlet and oxygen inlet connectors both use NIST connectors. This makes it easy to connect to air and oxygen supplies.
• Main Unit Bracket: Additionally, this bracket allows for simple fixing and removal of the main unit.
• Air Source Differential Pressure Alarm: If the pressure difference between the two sources (air and oxygen) exceeds 0.2 MPa, the system will trigger an alarm. The alarm will mute automatically when the gas pressure returns to normal.
• Mixed Gas High Flow Output Port: Lastly, this port allows for a high flow of mixed gas, ensuring quick oxygen delivery to patients.

Intended Purpose

The Air Oxygen Blender serves a medical purpose by integrating with oxygen tubes. It monitors and regulates oxygen concentration in the air-oxygen mixture. Moreover, it effectively controls high-pressure medical oxygen and air, ensuring a steady supply at specified flow rates. This regulation helps avoid the harmful effects of long-term pure oxygen use on the body.

Product Construction

This product consists of the main unit, which contains double gas pressure equilibrium valves, the main air-oxygen control module, and the air source differential pressure alarm module. Additionally, it features connectors and a flow meter.

Functions

The main unit of the Air Oxygen Blender accurately mixes air and oxygen in the preset ratio. It controls the output of mixed gas and adjusts the oxygen concentration and flow rate. Consequently, this ensures optimal patient care.

Operation Instructions

Setting Output Flow and Oxygen Concentration:

• Setting Output Flow: To set the output flow, turn the flow regulating knob counterclockwise to increase flow or clockwise to decrease it. The flow meter will show the current output flow value.
• Setting Oxygen Concentration: To set the oxygen concentration, turn the concentration regulating knob counterclockwise to increase concentration or clockwise to decrease it. The oxygen concentration value aligns with the top-end floating marker.

Limited Warranty

Finally, the Air Oxygen Blender comes with a limited three-month warranty against manufacturing defects. This provides peace of mind for healthcare providers.
