Electronic fluid flow rate controller for controlling the infusion of intravenous drugs into a patient
First Claim
1. An electronic fluid flow rate controller for controlling an electronically controllable fluid dispensing means which in turn controls the infusion of an intravenous drug into a patient, wherein the improvement comprises:
- a prerecorded data storage means containing prerecorded data identifying said drug and information about said drug;
patient information means for receiving information characteristic of said patient'"'"'s weight who is to receive said drug and for generating an input therefrom;
input means for automatically reading said information about said drug from said data storage means and for receiving said input from said patient information means and for thereafter automatically generating first signals pertaining to such information about said drug and information characteristic of said patients weight;
control means for receiving said first signals and thereafter generating a second signal derived from said first signals and which is indicative of a prescribed rate at which said drug is to be dispensed; and
means for transmitting said second signal from said control means to said fluid dispensing means for actuating said fluid dispensing means to deliver said drug at a rate dictated by said second signal.

Abstract
An 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.

17. An electronic fluid flow rate controller for controlling an electronically controllable fluid dispensing means which in turn generates signals which control the infusion of intravenous drugs to a patient wherein the improvement comprises:
-
a magnetic media having recorded therein information about an intravenous drug including, the name of the drug, the stock solution concentration of the drug and the recommended dosage range of the drug; magnetic media reading means for reading said magnetic media and for generating information signals indicative of said name, said stock solution concentration, and said recommended dosage range of said drug; patient information means including touchpad means for generating touchpad signals relating to the patient'"'"'s weight and the desired rate of infusion of the drug; display means for displaying said information relating to said name, said stock solution concentration, and said recommended dosage range of said drug; and a controller for receiving said touchpad signals from said touch pad means, and for receiving information signals from said magnetic media reading means generating control signals as a function of said touchpad signals and said information signals and for transmitting said control signals to said electronic controllable fluid dispensing means; and
indicating means for transmitting a signal for indicating if the desired rate of infusion exceeds the recommended dosage range.
