Negative pressure drainage to attract the patient's liquid for the purpose of negative pressure is too low or too high will affect the drainage effect. Negative pressure is too low attractive, drainage tube is easy to wound necrotic tissue, pus and other clogging, resulting in drainage failure, the wound can not be closed under negative pressure, affecting the treatment effect. Negative pressure is too high will cause excessive closure of the wound, the organization tightly wrapped drainage tube can not achieve good drainage treatment effect, and will cause tissue damage. The traditional portable negative pressure drainage device is a single negative pressure, can not meet the different needs of different wound pressure requirements.
Yiyang™Negative pressure drainage device with a unique negative pressure regulator, so that the pre-set bottle of high negative pressure (90kpa above) output can be between 10kpa-95kpa free to meet the clinical negative pressure drainage of different negative pressure requirements.
Increase the lymphatic drainage from the wound, the mechanism is by changing the pressure of the lymphatic vessels and colloid osmotic pressure, to speed up the edema and waste exclusion, so that the organization close to increase the organization have the opportunity to rely on the physical strength of the natural adhesion together, Accelerated healing is very useful.
Remove necrotic tissue
Promote leukocyte fibroblasts into the wound, where white blood cells can resist infection, produce growth factors, synthetic fibroblasts can produce collagen, used to fill and repair the wound.
Reduce the number of bacteria in the wound (because bacteria do not survive under negative pressure).
Increase growth factor (due to increased blood flow to the wound).
Increase venous filling, and thus speed up the removal of edema fluid.
Increase wound blood flow by increasing capillary filling.
Reduce edema (ie, extracellular fluid / intercellular fluid).
So that patients as soon as possible activities.
