A blood coagulation force detection system and method thereof. Wherein, the object-carrying table is used to carry a wave-carrying plate, to place the blood sample, so that when the blood sample is in contact with the air, a plurality of blood corpuscles will move to a blood coagulation place. The illumination device is used to illuminate the wave- carrying plate, to facilitate the micro-object lens aimed at the object- carrying table to observe the blood sample. A laser device, used to emit laser light, to clamp an observed blood corpuscle in the blood sample. Then, gradually reduce the intensity of laser light, when the observed blood corpuscle starts to move to the blood coagulation place, an instantaneous value can be obtained, and that is used to calculate the blood coagulation force. Through application of the system, the blood coagulation force can be detected with medical instrument in a scientific approach.本發明提供一種血液凝血力檢測系統及其方法,其係一載物台,可載放一載波片內可放置血液樣本,並使血液樣本與空氣接觸後,複數血球則會往一凝血處移動,並利用照明裝置以照明載波片,使對準載物台之顯微物鏡利於觀測血液樣本,以及一雷射光裝置,可發射出雷射光,以鉗住血液樣本內之一觀測血球後,再逐漸減弱雷射光線之強度,當觀測血球又開始往凝血處移動時,可得出一瞬間數值,並藉由瞬間數值得出血液凝血力。本創作可藉由醫學儀器,以科學的方式檢測血液凝血力。10...血液凝血力檢測系統12...載物台14...載波片16...照明裝置18...顯微物鏡20...雷射光裝置22...雷射光線24...透鏡26、26’...分色鏡28...電腦系統30...監控裝置32...載物台控制裝置34...取像元件
