<p><P>PROBLEM TO BE SOLVED: To provide a drip infusion monitoring device and drip infusion monitoring system, capable of accurately detecting liquid drips even when the liquid drips are small, an infusion solution is close to transparency, or a drip infusion cylinder is inclined by the movement of a patient. <P>SOLUTION: The drip infusion monitoring device detects the liquid drips falling inside a light transmissive drip infusion cylinder and calculates the number and interval of the falling drips. The monitoring device includes: a light emitting element and a light receiving element, which are arranged on the same side surface of the drip infusion cylinder; an amplification circuit for amplifying a signal from the light receiving element; a rectifying circuit for rectifying the amplified signal; a central calculation circuit for calculating the signal; a display means for displaying the calculation result; an alarm means for issuing alarm in response to the calculation result; and an interface for connecting the central calculation circuit to a host system. Thus, even when the liquid drips are small, the infusion solution is close to transparency, or the drip infusion cylinder is inclined by the movement of the patient, the liquid drips are accurately detected. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
