36 results about "Microtrauma" patented technology

Microtrauma is the general term given to small injuries to the body. Microtrauma can include the microtearing of muscle fibres, the sheath around the muscle and the connective tissue. It can also include stress to the tendons, and to the bones (see Wolff's law). It is unknown whether or not the ligaments adapt like this. Microtrauma to the skin (compression, impact, abrasion) can also cause increases in a skin's thickness, as seen from the calluses formed from running barefoot or the hand calluses that result from rock climbing. This might be due to increased skin cell replication at sites under stress where cells rapidly slough off or undergo compression or abrasion.

The device has a suction that operates in the casing of the needles. When the stamping of the microneedles occurs, this suction feature lift the skin from it's a regular lying surface. The suction feature promotes blood circulation which will promote cell repair and aide in regeneration. This vacuum like suction separates different layers of tissues, thus microtrauma from the needles is more confined to the layer desired; the epidermis. This also triggers an inflammatory response flooding the area with white blood cells, platelets, and other healing aids for the re-generation process.
