Device for Wound Healing
Utilises phononic structures etched into low cost substrates
Blood fluid properties (e.g. liquid to solid) can be easily controlled (even in presence of anti-coagulants. This is a reversible effect.
About Surface acoustic wave (SAW) devices are well known in the electronic industry. Researchers at the University of Glasgow have utilized the functionality of SAW devices to create a range of innovative solutions for different applications within the life sciences and healthcare industries. The innovative technology utilises phononic structures (two dimensional array of regular features) etched into low cost substrates to modify surface acoustic wave propagation to manipulate fluids at the surface of the substrate. Various fluid manipulation functions are achieved through the choice of materials used and the geometry of the phononic arrays. Different functions are selected through adjusting the frequency of the wave generated. Examples of functionality developed include sample movement, splitting, mixing, heating, concentration, atomization and cell lysis, and aggregation (clotting). SAW enable devices have been demonstrated that can be used to alter the fluid properties of blood. The device controls the properties of blood by changing the frequency, power or duration of the ‘acoustic-streaming’ thereby changing its state from a liquid to semi-solid or solid. Key Benefits: Blood fluid properties (e.g. liquid to solid) can be easily controlled (even in presence of anti-coagulants. This is a reversible effect. Devices can be used externally on skin or internally on blood vessels No damage is caused to surrounding tissue Simple to use device; no specialist training required It is gentle and could be used on infants Quickly stops blood flow Leaves wound uncovered Applications: This innovation has potential benefits for a wide range of uses where there is a need to alter or stem the flow of blood permanently or temporarily. The device could be used in the emergency services as an initial treatment for major and minor wounds before transferring patients to the Emergency Room consumer use in the home when treating minor cuts and wounds.
