OnQ: How does it work?

OnQ is an electronic micropump – a technology that produces liquid aerosol in a manner unlike any other technology currently available. As small as 15mm in diameter and wafer-thin, OnQ is comprised of a unique dome-shaped aperture plate containing over 1,000 precision-formed tapered holes, surrounded by a vibrational element.

When energy is applied, the aperture plate vibrates over 100,000 times per second. This rapid vibration causes each aperture to act as a micropump, drawing liquid through the holes to form consistently sized droplets. The result is a low-velocity aerosol optimized for maximum deep lung deposition.

OnQ aerosolizes efficiently, leaving virtually no residual liquid, and operates without using propellants or generating heat, thereby preserving a drug’s molecular integrity. OnQ works with most pre-existing liquid formulations and can be customized for an individual therapeutic application by adjusting the particle size. Combined, these advantages make OnQ ideal for delivery of a broad range of drugs including small molecules, proteins, peptides and liposome-based therapies.

OnQ Advantages 

• Aerosolizes a broad range of drugs in solution or suspension 
• Produces consistently sized aerosol particles for deep lung delivery 
• Rapidly delivers a predictable and reproducible dose 
• Minimizes deposition in the throat and mouth 
• Leaves virtually no residual drug 
• Emits a low velocity aerosol that adds no pressure or volume to breathing circuit 
• Operates silently, without generating heat or using propellants
