Abstract

A cartridge-based computer controlled self-injection device automatically regulates time and dosage administered to a patient. Cartridges can be electronically tagged so the injection device can determine the content, volume, expiration date, and physician prescribed dosage timetable. Authentication verifies the device and ensures the proper patient is using the device with the appropriate therapeutic injectant. Authentication further provides information controlling device operation including expiration dates and clock synchronization. Therapeutic injectant administration statistics, such as date and time of administration of a therapeutic injectant are stored and provide to a health care provider for monitoring. Patients can be notified of nearing or missed administrations.

Claims

1. A method for controlling an injection device, comprising:

receiving, via a receiver located in the injection device, control signals that include information concerning an injection, wherein the information includes a time of day when the injection is scheduled to be performed;

monitoring the time of day using a microprocessor located in the injection device; and

providing a notification to a patient through a transmitter located in the injection device that instructs the patient to perform the injection at the scheduled injection time of day.

2. The method claim 1, wherein the injection device is configured to accept a cartridge that contains the injectant to be injected into the patient, wherein the cartridge includes an electronically readable marking that includes the information concerning the injectant, further comprising reading an electronically readable marking on a cartridge to obtain the information concerning the injectant.

3. The method of claim 1, further comprising sending information about the injection via the transmitter to a health care provider for monitoring.

4. The method of claim 1, further comprising:

monitoring when the injection is performed using the microprocessor; and

notifying a health care provider via a message sent through the transmitter if the scheduled injection time of day passes without the injection being performed.

5. The method of claim 1, further comprising validating one or more settings of the injection device using the microprocessor prior to injecting the patient using the injector device.

6. The method of claim 1, further comprising determining whether the injection device is properly configured using the microprocessor prior to allowing an injection.

7. The method of claim 6, further comprising disabling the injection device using the microprocessor if the injection device is determined not be properly configured for an injection.

8. The method of claim 1, further comprising:

receiving one or more control signals in the receiver; and

automatically configuring the injection device for an injection using the received control signals.

9. The method of claim 1, further comprising controlling a plunger via the microprocessor to inject an injectant into a patient using the information.

10. The method of claim 9, wherein the injection device includes an actuator and a dosage control, further comprising, controlling the actuator using the microprocessor to rotate the dosage control by an amount sufficient to cause a proper dosage of injectant to be administered to the patient.

11. The method of claim 1, further comprising sending injectant administration data back to a health care provider using the transmitter.

12. The method of claim 1, wherein the injection device includes a memory, further storing injectant administration data in the memory.

13. The method of claim 11, further comprising sending injectant administration data stored in the memory to a health care provider.

14. A method for controlling an injection device, comprising:

reading an electronically readable label on a cartridge placed in the injection device to obtain information concerning an injection, wherein the information includes information concerning the injection to be performed;

monitoring conditions using a microprocessor located in the injection device to determine whether the monitored conditions have been satisfied to perform the injection; and

providing a notification to a patient through a transmitter located in the compartment of the injection device that instructs the patient to perform the injection when the conditions required to perform the injection have been met.

15. The method claim 14, wherein the information includes dosage information, further comprising controlling a plunger via the microprocessor to inject an injectant into a patient using the information.

16. The method of claim 14, further comprising sending information about the injection via the transmitter to a health care provider for monitoring.

17. The method of claim 14, wherein the information includes a time of day for performing the injection, further comprising:

monitoring the time of day using the microprocessor;

determining whether the injection was performed at the time of day included in the information using the microprocessor; and

notifying a health care provider via a message sent through the transmitter if the scheduled injection time of day passes without the injection being performed.

18. The method of claim 14, further comprising disabling the injection device if the injection device is determined not be properly configured for an injection.

19. The method of claim 14, further comprising sending injectant administration data back to a health care provider using the transmitter.

20. The method of claim 14, further comprising receiving one or more control signals from a health care provider that are used to control the injection.
