Abstract

Smart sensors are employed to determine one or more of drug identification, dose, flow rate, concentration, agglomeration, and degradation and/or other characteristics of drug administration that can be detected via sensing technology. A smart sensor(s) can be coupled to or retrofitted onto injection pen injectors and/or drug delivery cartridges and/or infusion sets or cannulae, enabling infusion sets, pen injector systems or drug delivery cartridges to improve tracking of drug self-administration and stop medication errors that occur primarily through self or automated injection (e.g., due to incorrect or incomplete dosing, excessive dose or rate, incorrect drug, or drug degradation).

Claims

1. A system for injecting medicament into a patient comprising:

an adapter configured to be detachably coupled between an injection pen housing and its needle assembly and to deliver the medicament from the injection pen housing to the needle assembly;

a sensor configured as a microchip provided in the adapter to sense at least one characteristic about the medicament or its delivery to the patient and generate sensor data; and

a device configured to wirelessly communicate with the sensor to obtain its sensor data.

2. A system as claimed in claim 1, wherein the device is a portable user interface.

3. A system as claimed in claim 1, wherein the device is configured to obtain wireless transfer of the sensor data and to provide wireless power to the sensor.

4. A system as claimed in claim 1, wherein the device employs one of RFID and SAW for providing wireless power to the sensor.

5. A system as claimed in claim 1, wherein the sensor detects at least one of drug identification, concentration, agglomeration, and degradation, and flow rate.

6. A system as claimed in claim 1, wherein the device comprises an application for performing at least one of interfacing with the adapter, processing the sensor data, setting alerts relating to the medicament or its delivery, and graphing and indexing information relating to medicament use and degradation for display.

8. A system as claimed in claim 1, wherein the device is a portable user interface.

9. A system as claimed in claim 1, wherein the device is configured to obtain wireless transfer of the sensor data and to provide wireless power to the sensor.

10. A system as claimed in claim 1, wherein the device employs one of RFID and SAW for providing wireless power to the sensor.

11. A system as claimed in claim 1, wherein the sensor detects dose amount.

12. A system as claimed in claim 1, wherein sensor data can be used to estimate insulin on board and confirm quality of dose.

7. A system for injecting medicament into a patient comprising:

a patch-like infusion device that can be adhered to a skin surface of a patient and comprises a reservoir of medicament and a needle manifold to deliver a designated amount of the medicament from the reservoir to the patient;

a sensor configured as a microchip provided in the patch-like infusion device to sense at least one characteristic about the medicament or its delivery to the patient and generate sensor data; and

a device configured to wirelessly communicate with the sensor to obtain its sensor data.

13. A system for injecting medicament into a patient comprising:

an infusion set that can be adhered to a skin surface of a patient and is configured to deliver a designated amount of the medicament from a pump to the patient;

a sensor configured as a microchip provided in the infusion set to sense at least one characteristic about the medicament or its delivery to the patient and generate sensor data; and

a device configured to wirelessly communicate with the sensor to obtain its sensor data.

14. A system as claimed in claim 13, wherein the device is a portable user interface.

15. A system as claimed in claim 13, wherein the device is configured to obtain wireless transfer of the sensor data and to provide wireless power to the sensor.

16. A system as claimed in claim 13, wherein the device employs one of radio frequency identification (RFID) and surface acoustic wave (SAW) technology for providing wireless power to the sensor.

17. A system as claimed in claim 13, wherein the sensor detects at least one of a site failure, a medication error and compliance.

18. A system as claimed in claim 13, wherein the sensor is a pressure sensor.

19. A system as claimed in claim 13, wherein the sensor detects at least one of a site failure, occlusion, and leakage.
