A device for detecting surface microcirculation blood flow includes a locator ring, an optical probe, a bio-optical blood flow detection device, and a signal processor. The locator ring surrounds a body part of a subject, and a sidewall of the locator ring has an opening. The optical probe is disposed in the opening and contacts a surface of the body part. The bio-optical blood flow detection device is connected to the optical probe to collect a microcirculation blood flow signal of the surface. The signal processor receives and analyzes the microcirculation blood flow signal.一種體表微循環血流檢測裝置,包含定位環、光學探頭、生物光學血流檢測裝置及訊號處理器。定位環用以環繞受試對象之部位,且定位環之側壁具有開口。光學探頭位於開口中,且接觸此部位之體表。生物光學血流檢測裝置連接至光學探頭,以收集體表的微循環血流訊號。訊號處理器則接收並分析微循環血流訊號。10‧‧‧體表微循環血流檢測裝置100‧‧‧定位環110‧‧‧開口200‧‧‧光學探頭300‧‧‧生物光學血流檢測裝置400‧‧‧訊號處理器410‧‧‧傳輸線
