DEVICE AND METHOD FOR ADMINISTERING BIOACTIVE SYNTHETIC SUBSTANCE

摘要

PROBLEM TO BE SOLVED: To be capable of precisely controlling the amount of a medicine administered by drip infusion or the like, and automatically changing the amount of the administered medicine corresponding to the situation of administration and the condition of a patient.;SOLUTION: A bioactive synthetic substance is stored in a reservoir 20. The bioactive synthetic substance of the amount corresponding to a control signal inputted from outside is discharged into a mixing chamber 22 by an inkjet type discharge device. Liquid drops of the discharged bioactive synthetic substance are detected by a light sensor 106, and a warning or the like is given when the liquid drops are not detected despite the discharge action is executed. An infusion liquid such as a physiological salt water is mixed with the bioactive synthetic substance when it flows into the mixing chamber 22 from a fluid tube 16 and flows down along an inclined bottom face 92, and is administered to the patient by the method such as drip infusion via a fluid tube 24.;COPYRIGHT: (C)2005,JPO&NCIPI
