Figure 3-10. System components
1 The nebulizer unit holds up to 6 ml of liquid medication.
The nebulizer unit is transparent to allow viewing of medica-
tion levels and aerosolization. After the nebulizer unit is con-
nected into the ventilator circuit, the silicone plug can be
opened and closed in between doses without causing loss of
circuit pressure. Inside the nebulizer unit is an OnQ Aerosol
Generator. This consists of a domed aperture plate with preci-
sion-formed holes to control the size of the aerosol droplets
and a vibrational element that creates a micro-pumping action
to aerosolize medication. Gravity brings the medication in con-
tact with the aerosol generator; where the liquid is drawn
through the aperture plate and converted into an aerosol.
2 The T-piece securely connects the nebulizer unit into the
breathing circuit. The T-piece connections are standard male
and female 22mm conical ports and connect to standard
patient breathing circuits. It is recommended that the Aeroneb
nebulizer be used in conjunction with a relevant T-piece sup-
plied by HAMILTON MEDICAL.
