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.
30 - 75 PSI Inlet Connectors
Each inlet connector incorporates a 30 micron particulate filter. After passing
through the filter, the gases travel through duckbill check valves that prevent
reverse gas flow from either the air or oxygen supply systems.
30 - 75 PSI Inlet Connectors
The MicroBlender is tested for compliance with ISO 11195E (1995), clause 6,
regarding reverse-gas flow as delivered.
Balance Module
The gases then enter the balance modules, which equalize the operating
pressures of the air and oxygen. The diaphragm in the balance module responds
to a difference in pressure and directs the movement (stroke) of each poppet
contained within the air and oxygen chambers. The movement of each poppet
adjusts the amount of gas fl owing through the balance module, equalizing
the air and oxygen pressures.
Air and oxygen hoses are
connected directly onto the
MicroBlender gas inlets.
