Abstract：Objective To observe the blood flow perfusion in human hand microcirculation by the laser Doppler perfu -sion imaging ( LDPI) technology .Methods The non-contact LDPI was used to detect the microcirculatory blood perfusion in 10 healthy adults′hands.Results The mean blood flow perfusion in human hand was 60.72 PU;the blood flow perfu-sion in nails of forefinger, thumb, medius, ring finger and little finger was (302.64 ±115.32), (339.99 ±137.53), (353.44 ±131.36), (356.53 ±129.05) and (389.39 ±146.32) PU, respectively;the blood flow perfusion in the upper parts of forefinger, thumb, medius, ring finger and little finger was (238.06 ±139.08), (195.64 ±78.15), (144.80 ± 73.76), (143.85 ±75.34) and (146.74 ±54.80) PU, respectively;and the blood flow perfusion in the lower parts of forefinger, thumb, medius, ring finger and little finger was (128.23 ±50.84), (105.65 ±41.84), (73.16 ±27.79), (81.61 ±31.18) and (71.15 ±25.13) PU, respectively.Conclusions We can observe that there are significant differ-ences among different parts of the back of hands by using LDPI technology .Forefinger and little finger nails show the lowest and highest blood perfusion levels , respectively;the perfusion levels in the upper part of finger nails decrease successively from thumb to little fingers;and in the lower part , thumb nail has the highest level of blood perfusion while little finger nail has the lowest one .
