The I-neb AAD Nebuliser

The I-neb is a small, battery powered, lightweight and virtually silent drug delivery device. It significantly reduces the inconvenience of conventional nebulizer/compressor therapy while delivering a precise, reproducible dose.1

Included as part of the Promixin package. Including replacement if faulty, lost or broken.

I-neb aerosol delivery
Patient's can't turn the I-neb on and walk away like a continuous flow nebuliser...

Unlike a continuous flow nebuliser, the I-neb AAD will only deliver medication when patients inhale, meaning you can be sure that patients are taking their required dose and the medication is not being wasted.


Adaptive Aerosol Delivery (AAD) algorithm for adaptive treatment

The I-neb pulses medication delivery into 50 to 80% of each inspiration, based on a rolling average of the last three breaths. Throughout the treatment, the I-neb provides continuous feedback to the patient. Upon successful delivery, the patient receives audible and tactile feedback.

Adaptive Aerosol Delivery (AAD) system optimizes drug delivery

This technology ensures optimal drug delivery by only delivering medication when the patient inhales. This gives the medication the best opportunity to reach deep into the lungs and greatly reduces waste to the environment. AAD delivers the right amount of medication, regardless of size or breathing patterns.

What is Tidal Inhalation Mode (TIM) and how does it work?

This video explains how the I-neb TIM mode works to deliver superior lung deposition compared with unguided breathing technique

The I-neb will work in TIM mode when the specific mouthpiece is attached. 

You can tell it is a TIM mouthpiece by checking this rectangle is in the corner of the mouthpiece

How does aerosol delivery with an I-neb AAD device compare to a constant flow nebuliser?

The delivery of colistimethate sodium (CMS) by three different nebulisers, using a breath simulator, was investigated in four different inhalation : exhalation (I:E) ratios.

What are Inhalation : Exhalation (I:E) ratios?

Inhalation : Exhalation (I:E) ratios provide the average ratio of time taken on inspiration and expiration.


Resting Inhalation : Exhalation (I:E) ratio times during tidal breathing can vary depending on disease and disease severity.


Patients with cystic fibrosis can exhibit a range of I.E. ratios which vary from approximately 1:1.2 to 1:53.


How does this affect patients using nebulisers?

Continuous flow nebulisers

As displayed in the below diagram, as patients disease progresses and they gradually spend more and more time exhaling than inhaling.


As continuous flow nebulisers are always producing aerosol, this means increasingly more aerosol is pumped into the environment and less into the lungs where it is needed as the disease progresses

I-neb AAD (TIM mode)

As the I-neb AAD only produces aerosol when patients are inhaling, more of the aerosol ends up in the lungs.


The I-neb's AAD algorithm also adapts to patients breathing, encouraging them to take longer, deeper breaths which gives the best opportunity for the aerosol to reach deep into the lungs and greatly reduces waste to the environment

Constant output mesh nebuliser (eFlow rapid)

  • The average results show that the majority of the delivered dose is exhaled.

  • Increasing the time spent during exhalation, as might occur with patients with more severe disease, reduces the amount of drug deposited in the lungs, and increases the amount exhaled.

Pulsed delivery (I-neb AAD nebuliser)

  • The amount of aerosol wasted to atmosphere was very low.

  • The predicted dose delivered to the central and peripheral areas of the lungs was higher than for the constant output nebulizer, despite the fact that for the higher dose only 1 vial of colistimethate sodium was needed to fill the nebulizer.

  • Longer I:E ratios had limited affect on dose delivered to the lungs

How does device orientation affect dose delivery?

The I-neb contains an out of angle sensor helps the patient with nebulizer orientation.

Device orientation

The delivered volume was measured for different nebulisers (I-neb AAD and eFlow rapid) at orientations of -45˚, 0˚ and +45˚

The results show that the eFlow rapid was significantly affected by device orientation compared with the I-neb, which remained consistent at all tested device angles


How does the I-neb deliver different doses?

The I-neb has different chamber types for different medications

I-ne does

The I-neb support three chamber types
