Nitrogen cylinder in a sealed pressure cylinder, sealed high pressure gas (nitrogen incombustibility). Using this as a high-pressure gas spring reaction force to use. So that patients only big knee bending angle can sit down and relax, can reduce the burden on the knee. Nitrogen cylinder compact and lightweight but great resilience (reaction), the long trip back to stretch almost unchanged. When the patients got ready to lean forward, there is sufficient strength to hold up a patient resilience, helping patients to stand, but is yet to contribute a case of knee, thereby reducing moment in patients with small-angle stand up to knee load.
