The equipment for the destruction of viruses by means of complementary radiation consists of a technology focused on weakening the fatty layer covering certain viruses, to cause the indirect destruction of them. This technology utilizes intense, modulated light radiation, the principal emitters thereof being 460-nanometers LEDs which, with the technology of the invention, emit secondary radiation in a band ranging from 400 to 460 nanometers, in order to achieve the weakening and destruction of the fatty layer that covers viruses such as SARS-CoV-2. This light radiation is complemented with ultrasound pulses that complete the destructive effect of the interior of the virus. For this purpose, technology involving emission by means of stratified quantum excitation is employed, which uses monochromatic light-emitting diodes to achieve very-high-intensity polychromatic emissions highly controllable regarding tissue penetration.

An osseointegrated fixture of a percutaneous osseointegrated prosthesis (POPs) anchors directly into a bone of a residual limb within an amputation stump. By anchoring directly into the bone, the POPs provides improved mobility, comfort, and function for an amputee, but an interface between an opening in the skin and the osseointegrated fixture, which allows the anchoring directly into the bone, is prone to infection by microbes. An anti-microbial device can be attached to and/or embedded within an extracorporeal portion of the osseointegrated fixture to irradiate at least a portion on the interface with at least one wavelength of light selected for its antimicrobial effects.
