DESCRIPTION
The BlenderBuddy 2 is an accessory designed for use with air/oxygen blenders. It utilizes a Maxtec Designed for Blenders (DFB) flowmeter which is designed and calibrated specifically for air/oxygen blenders to provide increased accuracy compared to standard flowmeters. By utilizing dual-scale graduations, the flowmeter provides two flowmeters in one for increased accuracy at lower flows. The flowmeter features a high-quality acrylic block body and preci-sion valve. The BlenderBuddy 2 also provides a sensor analysis port which may be used to measure the gas concentration from the blender. A small continuous sensor bleed is provided which enables gas analysis regardless of which outlet port is used on the blender.
INTENDED USE
The BlenderBuddy 2 is a flowmeter intended for use with an air/oxygen blender
and is to be used by physicians, respiratory therapists and other authorized
hospital personnel to adminis-ter selected doses of medical gases to a patient
The BlenderBuddy 2 also contains a gas analy-sis port which may be used with a
suitable oxygen analyzer to measure the gas concentration.
WARNINGS
-
Read this User Manual before installing or operating the BlenderBuddy 2.
-
This manual instructs a professional to install and operate the BlenderBuddy 2. This is pro-vided for your safety and to prevent damage. If you do not understand this manual, DO NOT USE the BlenderBuddy 2 and contact your provider.
-
Use BlenderBuddy 2 only for its “Intended Use” as described in this manual.
-
This product should only be used under proper supervision of a healthcare professional.
The BlenderBuddy 2 is for use with air/oxygen blenders only. The accuracy of the flowmeter will be affected if the BlenderBuddy 2 is used in any other way.
Follow all manufacturer instructions for proper air/oxygen blender and bleed operation. -
ALWAYS activate the blender bleed when necessary according to the blender manufacturer instructions. Failure to do so may result in inaccurate concentrations from the blender.
-
The flowmeter is capable of delivering flows greater than the indicated value (flush flow). Adjusting the flow beyond the indicated range will result in an undetermined flow.
-
The BlenderBuddy 2 is capable of delivering gas mixtures at pressures equal to the blender outlet. Always confirm proper setup before patient use.
-
Check for leaks and proper operation before placing the BlenderBuddy 2 into service.
-
ALWAYS confirm prescribed flow and oxygen concentration before administering to patient and monitor on a frequent basis.
-
The BlenderBuddy 2 may contain magnetic, ferrous material and is NOT for use in MRI environments.
-
DO NOT connect to source pressure greater than 100 psi.
-
DO NOT disassemble the BlenderBuddy 2 while pressurized.
-
DO NOT use substitute parts.
-
DO NOT use lubricants on O-rings.
-
DO NOT use the BlenderBuddy 2 if you suspect components are damaged, altered, or missing. Inspect unit before each use.
To Reduce the Risk of Fire or Explosion:
- ALWAYS follow ANSI and CGA standards for Medical Gas Products and Oxygen Handling. DO NOT use or store oils, greases, organic lubricants or any combustible materials on or near the BlenderBuddy 2.
- DO NOT use near any type of flame or flammable/explosive substances, vapors or atmosphere.
- DO NOT smoke in an area where oxygen is being administered.
CAUTION
- The BlenderBuddy 2 must be operated with the Flowmeter in a vertical, upright position.
- Gas temperatures other than 70° F (21°C) may affect the accuracy of the indicated flow. DO NOT drop the BlenderBuddy 2.
- DO NOT attempt to sterilize the BlenderBuddy 2
- DO NOT clean with aromatic hydrocarbons.
- DO NOT immerse the BlenderBuddy 2 in any kind of liquid.
- DO NOT over-tighten knob when turning off. This may damage the flow meter.
DO NOT occlude or plug the gas sensor port.

INSTALLATION/OPERATION
NOTE: Low flow BlenderBuddy 2 models (3, 15 and 30 LPM) should only be used with Low Flow blenders. High Flow BlenderBuddy 2 models (70 LPM) should only be used with High Flow blenders. Use outside these applications may result in flowmeter inaccuracies.
Align the flowmeter in an upright, vertical
position with the blender and firmly tighten the fitting.
NOTE: Ensure the fitting is completely tightened to prevent rotation
during use.
WARNING: Follow all manufacturer instructions for proper blender bleed
operation. A blender bleed is typically required to maintain mixing accuracy
for flows less than 3LPM on low flow blenders and below 15LPM for high flow
blenders. Failure to activate the blender bleed may result in inaccurate
concentrations from the blender. 
NOTE: A small continuous sensor bleed is provided to the analysis port which enables gas analysis regardless of which outlet port is used on the blender.
FLOWMETER OPERATION
Adjust the flowmeter to the desired set-point as read by the center of the float ball
- To increase flow—turn knob counter-clockwise
- To decrease flow—turn knob clockwise
WARNING: The flowmeter is capable of delivering flows greater than the indicated (flush flow). Adjusting the flow beyond the indicated range will result in an undetermined flow.
CLEANING & MAINTENANCE
Cleaning
Exterior surfaces may be cleaned using a cloth and mild detergent, isopropyl alcohol solution, or germicidal wipe.
Maintenance
The BlenderBuddy 2 does not require any periodic maintenance or contain any user service-able components.
