Attorney, Agent or FirmInternational ClassA61M 005/00AbstractAn electronic controller connected to an electronic infusion pump which regulates the rate at which a drug is infused into a person. A magnetic card reader reads from a magnetic card, the name of the drug, the stock solution, concetration recommended dosage rate and warnings. The weight and the desired dosage rate of the patient is fed by a touch pad to the controller. The controller automatically computes the infusion rate and notifies via a display whether the desired rate exceeds the recommended rate. Also displayed are details about the drug, the length of time the patient has been infused, the amount of drug infused, and the dosage rate since the last rate change.Field of SearchMEANS FOR INTRODUCING OR REMOVING MATERIAL FROM BODY FOR THERAPEUTIC PURPOSES (E.G., MEDICATING, IRRIGATING, ASPIRATING, ETC.)With tubular injection means inserted into body Flow control By self-acting means or condition responsive sensor Material flow varying means controlled by condition responsive sensor Sensor responsive to body condition Sensor controls pump, motor, or pressure driven means Material impelled by pump Means for controlling material flow to or from body, or metering a predetermined dose or amount Having fluid responsive means (e.g., check valve, etc.) Having medical information (e.g., name of patient or medicament, etc.) means | |
