Devices and methods for detection of internal bleeding and hematoma

A device for detection of internal bleeding in a patient's body, the device comprising:

• an IR light source configured to generate light in the Infra-Red (IR) spectral range;
• an IR light detector configured to detect light in the Infra-Red (IR) spectral range;
• an optical interface comprising
• at least one first optical channel configured to transmit IR light generated by said IR light source through an area of a skin of said patient, into an internal layer of the body, and
• one or more collection component, comprising at least one second optical channel, configured to collect reflected IR light from said area of said skin, and deliver said collected IR light to said IR light detector, and
• a reference signal source configured to generate a Radio-Frequency (RF) reference signal at a frequency of about 0.5 MHz-3 MHz,
• a reference signal detector configured to detect said reference signal,
• a reference signal interface configured to directly and independently from the IR source deliver through said area of the skin of the patient the reference signal from said reference signal source into said internal layer and to collect and deliver a collected reference signal to said reference signal detector, and
• a signal processing module comprising a processor configured to normalize measurement results of the detected IR light, detected by said IR detector, according to measurement results of the detected reference signal, detected by said reference signal detector, thereby detecting the internal bleeding in the patient's body.
