Abstract：To design an abdominal bleeding detecting instrument based on near -infrared intensity and explore the experimental application.A set of abdominal bleeding detecting system based on near infrared light was developped and the in vitro model of abdomi-nal bleeding was established.The distribution of photons in the abdominal tissue and the effective detecting depth of the system were al-so studied.Results showed that light with a wavelength of 760 nm and 850 nm could be clearly distinguished between normal abdomen and the bleeding under the abdomen associated with damage.The effective detection depth of the present system was 2.5 cm.Detection linearity of the light of 760 nm was better than that of 850 nm.Near infrared technology has a potential for the detection sensitivity in the shallow abdominal bleeding detection.
