Mircorcirculation observation instrument is an advanced medical instrument, It's use for check up the capillary vessel of finger, it can display realtime and clearly. Abroad use in early diagnosis kinds of deaseases,for example, diseases of blood vessel, hypertension, apoplexy,saccharine diabetes,and rheumatic arthritis etc.Operate is briefness, quick, no hurt and any side-effect.,at the same time , it's very import in the many fileds, like health protection, health consultation, reconnaissance, hairdressing sonsultation.

The effects of Chinese medicines on micro-circulation and blood flow velocity in arteries of the lower limbs were observed in 33 patients with arteriosclerotic obliteration (ASO). The results showed that the integral values of micro-circulation after treatment were obviously higher than those before treatment (P<0.05 or P<0.01). Blood flow velocity in arteries of the lower limbs determined with the color Doppler ultrasound detecting method after treatment were also obviously higher than those before treatment (P<0.05 or P<0.01). In this series of 33 ASO patients, the markedly effective rate was 36.36%, and the total effective rate was 63.64%. The observation indicates that the recipe prescribed according to the principle of supplementing qi and activating blood circulation can effectively improve micro-circulation in ASO patients, and accelerate blood flow in arteries of the lower limbs.
