What is electrostatic spraying?

Electrostatic phenomena arise from the forces that electric charges exert on each other.  Such forces are described by Coulomb's law. 

Electrostatic spray systems turn liquid into charged aerosols that are actively attracted to the intended targeted surface.

Advantages of electrostatic application

Through its proven and proprietary electrostatic spraying technology, OMEA is designed to advance the standard of care for acute and chronic wounds and burns.   

 

An enormous amount of published data supports the advantages of using electrostatics to enhance the objective of achieving 100% coverage in applying a topical therapeutic to a specific targeted tissue. 

What is electrospinning?

Using our electospinning cartridge the OMEA is capable of using a number of different polymers which, through electrostatic forces, produces nanofibers on the desired tissue target. This process is called electrospinning.

Advantages of Electrostatic Spraying

Improved Adhesion and Infiltration

Electrostatically charged therapeutics facilitate instant adhesion to the target tissue.

 

The charged particles hold their cationic or anionic charge for several seconds reducing dripping or running of therapeutic material into non-targeted tissue.

More Uniform and Comprehensive Wound Coverage

Electrostatically charged therapeutics facilitate instant adhesion to the target tissue.

 

The charged particles hold their cationic or anionic charge for several seconds reducing dripping or running of therapeutic material into non-targeted tissue.

Clinical Implications

Potential for enhancing and maximizing the desired outcome of applying a specific therapeutic to a targeted tissue.

Electrostatically applied therapeutics enable highly efficient, large surface-area-to-volume ratio, enabling significant greater coverage with less material (volume) use.  

Advantages of Electrospun Wound Bandages

Compositional Mimicry

Electrospinning can produce a 3D ‘basket-weave’ structure which mimics the ordered structure of the dermis. Unlike traditional dressings, the electrospun fibers can conform to the various wound dimensions and contours.

Structural Mimicry

Electrospun fibers conform to the wound bed structure while the semi-permeability of the fibrous matrix facilitate an aerobic healing environment.

Mechanical Mimicry

Electrospun wound dressings exhibit significant tensile strength as well as flexibility of movement.

Electrospun nanofibers form a biodegradable mesh that can promote hemostasis. Additionally, a wide variety of polymers can be used allowing for the incorporation of a wide range of therapeutic molecules.
