Instruction Manual MicroBlender Section 1: Introduction The MicroBlender is a lightweight, compact, air-oxygen blender that provides precise mixing of medical-grade air and oxygen. The MicroBlender provides oxygen concentrations from two gas-outlet ports. Low Flow MicroBlender High Flow MicroBlender The MicroBlender can be used in conjunction with: Oxygen hoods Resuscitation bags Masks Transports Nasal cannulas Treatments L2965–101 Rev.
MicroBlender Instruction Manual Section 2: Operation Overview The MicroBlender provides selection of oxygen concentrations by means of a single control knob located on the front of the unit. Oxygen concentrations ranging from 21 to 100% are available. Outlet Flow Range Bleed Flow Low Flow MicroBlender Primary, Left Side 3-30 LPM No Bleed Flow Auxiliary, Right Side 0-30 LPM 2.5-3.
Instruction Manual MicroBlender Gas Inlets The ports located on either side of the unit allow flexibility for the clinician. The MicroBlender operates by using two 30–75 PSI gas sources that enter the device through DISS or NIST connectors located on the bottom the unit. Air and oxygen hoses are connected directly onto the MicroBlender gas inlets. 30 - 75 PSI Inlet Connectors Each inlet connector incorporates a 30 micron particulate filter.
MicroBlender Instruction Manual Proportioning Module From the balance module, the gases flow into the proportioning module and mix according to the oxygen percentage selected with the MicroBlender control knob. This module consists of a double-ended poppet positioned between two valve seats. One valve seat controls the passage of air and the other valve seat controls the passage of oxygen into the MicroBlender outlets.
Instruction Manual MicroBlender Similarly, if the blender is set to deliver 100% concentration and AIR source pressure is reduced or lost, the unit may not alarm because it will continue to deliver the selected 100% concentration. If the blender is left connected to source gases but is not being used (i.e., no output flow or bleed flow) the unit will not alarm if a 20 ±2 PSI or greater pressure differential develops.

Instruction Manual MicroBlender Section 3: Warnings, Cautions, and Notes The MicroBlender should be operated by trained, qualified medical personnel under the direct supervision of a licensed physician. Before clinical application, the following WARNINGS, CAUTIONS and NOTES should be read and understood. Note: A specific point is made to assist the operator in understanding the equipment. Caution! Conditions may exist that could damage the MicroBlender or other pieces of equipment.
MicroBlender Instruction Manual Warning! 8 If either the air or oxygen gas source fails, the MicroBlender alarm sounds, alerting the clinician that a condition has occurred that may significantly alter the FiO2 and flow output from the MicroBlender. If either the air or oxygen gas source pressure is reduced or increased creating a pressure differential of 20 ±2 PSI, the MicroBlender alarm sounds. This condition significantly alters the FiO2 and flow output from the MicroBlender.
Instruction Manual MicroBlender Section 4: Controls and Alarms The MicroBlender delivers selected oxygen concentrations through two outlet ports. The outlet ports, although similar in appearance, have different flow range specifications. The two outlet ports provide a choice of flow ranges based on the application desired. Both outlets may be used simultaneously, provided the combined flows do not exceed the rated maximum flow capability of the MicroBlender.
MicroBlender Instruction Manual Section 5: Performance Checks Before placing the MicroBlender into clinical use, perform the following performance checks. Warning! flow If the MicroBlender does not function as described below, contact CareFusion (refer to the company information at the beginning of this manual). DO NOT use the MicroBlender until correct performance is verified. Low Flow MicroBlender Alarm / Bypass Check Reverse Flow Check Adjustment Response 1.
Instruction Manual MicroBlender High Flow MicroBlender Alarm / Bypass Check Adjustment Response 1. Connect the 50 ±5 PSIG* air/ oxygen source gases. Adjust the control knob to 60%. Connect the flow meter to the auxiliary outlet and set the flow to 2 LPM. 1. Alarm/Bypass should not activate. 2. Connect an oxygen flow meter to the auxiliary outlet to activate the auxiliary bleed and disconnect the 50 PSIG* air source from MicroBlender. 2.
MicroBlender Instruction Manual Reverse Flow Check 1. 2. 3. 4. 5. 12 Connect both gas supply hoses to the inlet connectors. Connect the oxygen hose to an oxygen pressure regulator, and submerge the free end of the air hose in a container of water. Do not make a connection to either outlet (so that they remain closed). Slowly adjust the oxygen pressure regulator to increase pressure from 0 to 50 PSIG* while looking for bubbles to rise from the submerged air hose connector.
Instruction Manual MicroBlender Section 6: Troubleshooting Guide Problem Potential Cause Corrective Action Oxygen concentration discrepancy between MicroBlender settings and analyzer. 1. Analyzer out of calibration. 1. Calibrate the analyzer 2. Flow requirements are below the specified LPM range. 2. Correct the flow. Verify that the correct outlet port is being used. Each outlet port has a different flow range. 3. Gas supply is contaminated. 3. Correct the contaminated gas supply.
MicroBlender Instruction Manual Problem Potential Cause Corrective Action MicroBlender is accurate only when inlet gas pressures are equal. 1. Balance module not functioning properly. 1. Contact CareFusion for repair. 2. Both air and oxygen gas sources are below 30 PSIG. 2. Correct the low pressure condition. 14 L2965–101 Rev.
Instruction Manual MicroBlender Section 7: Cleaning and Sterilizing Note: User is to consult with the manufacturer of the ETO equipment for aeration time. Use an all purpose liquid cleaner on the exterior. Do not steam autoclave or otherwise subject the MicroBlender to temperatures over 145°F. Do not immerse the assembled Low Flow MicroBlender in liquid decontamination agents. Do not use any strong solvent cleaners on labels or markings.
MicroBlender Instruction Manual Section 8: Maintenance and Service Caution! The MicroBlender should only be serviced or calibrated by a CareFusion trained technician. CareFusion equipment is designed to provide the maximum amount of utilization with a minimum amount of maintenance.
