REF CONTROL
FUNCTION
30. Power Switch Turns power to the Model 3100B System on and off. This power switch also functions as a circuit
breaker in case of a power overload. If the circuit breaker trips, be sure to locate the problem
causing the power overload before resetting the breaker. This switch is a standard rocker switch
which breaks both sides of the power line as does the built-in circuit breaker.
31. Oscillator
Compartment
(Bellows)
Attaches to 1 1/4" I.D. inspiratory limb of patient circuit and is held in place by four quarter-turn
fasteners.
32. Pa Control Valve Green Luer bulkhead fitting for connection to green 1/16" I.D. tubing that runs to the control input
of the Pa Control Valve on the Patient Circuit. Consult assembly procedure in Chapter 6 for
details on attachment of this control line to its valve. This line should be replaced periodically
during scheduled preventive maintenance of the HFOV.
33. Dump Valve Control Red Luer bulkhead fitting for connection to red 1/16" I.D. tubing that runs to control input of Dump
Valve on Patient Circuit. Consult assembly procedure in Chapter 6 for details on attachment of
this control line to its valve. This line should be replaced periodically during scheduled preventive
maintenance of the HFOV.
34. Pa Sense White Luer bulkhead fitting for connection to clear 1/8" I.D. tubing that runs to the Airway
Pressure Port of the Patient Circuit for the purpose of transmitting the Pa signal to the pressure
transducer within the Control Package. Consult assembly procedure in Chapter 6 for details on
attachment.
35. Pa Limit Valve
Control
Blue Luer bulkhead fitting for connection to blue 1/16" I.D. tubing that runs to control input of Pa
Limit Valve on Patient Circuit. Consult assembly procedure in Chapter 6 for details on attachment
of the control line to its valve. This line should be replaced periodically during scheduled
preventive maintenance of the HFOV.
36. Water Trap Condensate should drain into the water trap if the Patient Circuit is positioned properly. There is a
small (.025" diameter) hole at the top of the water trap to allow air to escape as it fills.
37. Water Trap Drain
Valve
Allows draining of water condensate. Water is drained from the bottom when the stopcock is
opened. The contents of the water trap can be drained while the Model 3100B is still operating as
long as the water seal between the ventilator and the bottom drain is not broken. This can be
accomplished by always leaving a small amount of water at the bottom of water trap after
draining. Follow the instructions in Chapter 8 regarding cleaning and disinfecting the water trap
and valve mechanisms.
CAUTION
Ensure that the stopcock is closed prior to performing a Patient Circuit Calibration. If the Water Trap Stopcock is
left open, Patient Circuit Calibration (39–43 cmH20) may not be achievable, and the deliverable Pa will be
reduced.
38. Bellows Fastener Four quarter-turn fasteners that hold the bellows (Oscillator Compartment) in place in front of
the oscillator piston.
39. Patient Circuit Cradle For attachment of Patient Circuit. Refer to Chapter 6 for assembly and adjustment instructions.
40. Humidifier Tubing The external humidifier is connected between the “Outlet To Humidifier” on the rear of the
Control Package and the Bias Flow Inlet on the Patient Circuit. In Figure 4.3, the humidifier
tubing is shown connected to the patient circuit without the humidifier inline.
Only the 3/8" tube supplied with the Patient Circuit should be used.
41. Bulkhead Luer Fittings There are four bulkhead luer fittings on the front of the oscillator compartment for connection to
the three valve caps and pressure sense port on the patient circuit.
42. Hold Down Strap Secures the patient circuit to the Patient Circuit Cradle. This keeps the circuit in a stable
position.
