ULTRASONIC NEBULIZER
Accessories, consumables and spare-parts are no longer available from the manufacturer in 2022.
Stopped in June 2018 and becomes NST in consultation of the TB working group (Gabriella Ferlazzo). The ultrasound nebulizer can be replaced by the Nebulizer + compressor PARI Boy Pro EEMDNECE6-- (see “replaced by” at bottom of the page).
Definition
Used with a medication cup this device generates aerosolised medication (finely dispersed airborne droplets) for inhalation by a patient with respiratory disorders.
Without a medication cup, the device can be used for induction in order to obtain sputum samples necessary for the diagnosis of tuberculosis.
It consists of a mains electricity (AC-powered) electronic oscillator, an ultrasound transducer (piezoelectric crystal), a coupling basin, a nebulizer chamber and a fan. A high frequency (e.g., 1-2 MHz) electrical current is applied to the crystal within the oscillator circuit converting it to mechanical vibrations which produce sound waves of 1 to 2 MHz. The coupler (water or saline) transmits the sound waves to the (medicated) solution in the nebulizing chamber.

Instructions for use
Read carefully instructions manual before use.
It is recommended to follow the manufacturer's instructions for use and maintenance of the device.
Precautions for Use
Contact your biomedical officer in order to see the need to protect the apparatus with a double conversion UPS (see related articles below).
Maintenance
- The anti-bacterial filter is for single use it should be replaced between each patient and at least every week if used with the same patient.
- All other parts must be sterilized by steam autoclave. CAUTION: remove the quartz module before!
- Mind not to scratch the piezoelectric crystal when cleaning.
- The machine should be dismantled, cleaned and disinfected after each patient with 0.5% detergent-disinfectant solution for medical equipment (i.e. 25 ml = 1 stroke of dosing pump for 5 litres water).
