摘要:
An apparatus (1), system and method for monitoring fluid flow in an intravenous drip are disclosed. The apparatus holds a drip chamber (4) in relation to an imaging device or processor (11, 19, 18, 20). Distortion of a background image or pattern due to refraction of light through the flowing, dripping liquid is detected by the processor. The estimated flow rate into the drip chamber (4) is then used to generate an error signal to control a valve actuator (6) with a closed loop control system (14).
