Mesh-type nebulizers

There are two categories of mesh-type nebulizers: static mesh and vibrating mesh nebulizers.

  • Static mesh nebulizers apply pressure on the inhalation solution in order to force it through a static sieving mesh.
  • Vibrating mesh nebulizers work by using deformations or vibrations of the mesh to push the inhalation solution through the aperture plate. A ring-shaped piezoelectric element having contact with the mesh plate sets same into vibrations. The inhalation solution is in direct contact with the sieving mesh. Mesh plate apertures are ca. 3.8 Ám in diameter, which is the smallest size technically achievable (for reasons of blocking). The mesh generates a monodisperse aerosol cloud whose finest droplets are only slightly smaller than the aperture diameter. Larger droplets are then formed by coagulation while the smaller ones are formed by evaporation.

Mesh nebulizers can be operated on battery supply, and they are small and portable units. Mesh-type nebulizers are efficient, quiet, and suited to aerosolize all inhalation solutions. They generate monodisperse aerosols containing particles in the size range of up to 4.5 or 5Ám. Aerosol losses may occur since mesh nebulisers work by discharging the aerosol in a continuous manner. Mesh-type nebulizers require intensive cleaning and careful handling. Their membrane is prone to getting blocked and may need to be replaced several times a year.
