Vaccume therapy Nope, it's not about putting cans in. It is a vacuum therapy that aims to stimulate wound healing. This is achieved by creating a localized negative pressure. The effect of accelerated healing is achieved by: - Reducing the swelling; - Creation of unfavorable conditions for bacterial life; - Increased blood flow to the wound; - Stimulating the process of healing of the wound edges. This method is rarely used. Vacuum therapy of wounds is necessary mainly for people with immunodeficiency.
