Abstract

A motorized infusion injection system having an information card record side unit 10 and an information card user side unit 20. Unit 10 includes an information card 11 on which medication information is written for a patient, a reader/writer 12 that can read/write the medication information from/on the information card 11, and an input 13 for inputting the medication information. Unit 20 includes a reader 21 for reading out information from the information card 11, an input 22 for inputting personal information of a patient and a controller 23 to generate a medication signal. A transducer 24 receives the medication signal and transduces the medication signal to a mechanical signal, and a motorized PCA pump 25 connected to an infusion storing-container 30 that contains a given infusion 31 and to an injector 40 that injects the infusion into a body of the patient for supplying the infusion 31 from the infusion storing-container 30 to the injector 40.

Claims

1. A motorized infusion injection system comprising an information card record side unit, and at least one information card user side unit, said information card user side unit being physically separate from said information card record side unit;

said information card record side unit being adapted to communicate with an information card on which medication information is written in accordance with a case of a patient and comprising, a reader/writer that can read/write said medication information from/on said information card, and an input means for inputting said medication information into said reader/writer; and

said at least one information card user side unit being adapted to communicate with said information card and comprising a reader for reading out information from said information card, an input means for inputting personal information of a patient into said information card user side unit, a controller for receiving said medication information from said reader and said personal information from said input means of said user side unit to generate a medication signal, a transducer for receiving the medication signal from said controller to transduce said medication signal to a mechanical signal, and a motorized Patient Controlled Analgesia pump, said pump being adapted for connection to an infusion storing-container that contains a given infusion and to an injector that injects said infusion into a body of the patient for supplying said infusion from said infusion storing-container to said injector.

2. An infusion injection system according to claim 1 further comprising an information card coupled to at least one of said units.

3. An infusion injection system according to claim 2 wherein said information card is selected from one of a magnetic card, an IC card, and an optical card.

4. An infusion injection system according to claim 1 further comprising an infusion storing-container that contains a given infusion and to an injector that injects said infusion into a body of the patient for supplying said infusion from said infusion storing-container to said injector.
