Abstract

A system for detecting disease progression can include an injection device configured to deliver medicament to a patient, one or more load sensors, one or more motion sensors, and a processor configured to read data from one or more of the load sensors and motion sensors and produce an output for display to a user.

First claim

What is claimed is:

1. A diagnostic measurement system for performing diagnostic measurement of a disease, comprising:
an injection device configured to deliver medicament to a patient, the injection device comprising:
a proximal end;
a distal end;
an upper portion positioned between the proximal end and the distal end;
a lower portion positioned between the proximal end and the distal end, the lower portion being distal to the upper portion; and
a plurality of force sensors disposed on lateral surfaces of the upper portion, each of the plurality of force sensors configured to mate with a finger of a plurality of fingers of the patient, wherein the plurality of force sensors are configured to measure a grip strength of the patient when the patient squeezes the injection device while the plurality of fingers of the patient are mated with the plurality of force sensors; and

a processor configured to read data from the one or more force sensors and display a measurement related to the grip strength of the patient.

2. The system of claim 1 , further comprising one or more motion sensors integrated with the injection device.

3. The system of claim 1 , wherein the one or more force sensors are positioned within the interior of the injection device.

4. The system of claim 1 , wherein the one or more force sensors are positioned on the exterior of the injection device.

5. The system of claim 1 , further comprising a transmitter configured to transmit data to an external device.

6. The system of claim 1 , further comprising a display for displaying the measurement.

7. The system of claim 1 , wherein the processor is further configured to provide instructions to a user to perform one or more actions for detection by one or more of the force sensors.

8. The system of claim 7 , further comprising one or more indicators, wherein the processor is configured to provide instructions by activating one or more indicators.

9. The system of claim 8 , wherein the indicators comprise one or more of visible, audible, and haptic indicators.

10. The system of claim 7 , wherein the processor is configured to provide instructions in response to one or more of receipt of a user input, receipt of a signal from an external device, a predefined time schedule, or an injection event.

11. The system of claim 1 , wherein the grip strength is a measure of a compressive force of the patient's hand and fingers.

12. The system of claim 1 , further comprising one or more overmolds positioned over the plurality of force sensors, the overmolds comprising one or more textured surfaces, each textured surface configured to provide an indication of a position for placement of one of the plurality of fingers of the patient for mating with one of the plurality of force sensors.

13. A diagnostic measurement system for performing diagnostic measurement of a disease, comprising:
an injection device configured to deliver medicament to a patient;
a plurality of force sensors disposed on lateral surfaces of the injection device and configured to measure a grip strength of the patient when the patient squeezes the lateral surfaces of the injection device;
one or more overmolds positioned over the plurality of force sensors, the overmolds comprising one or more textured surfaces, each textured surface configured to provide an indication of a position for placement of a finger of a plurality of fingers of the patient for mating with one of the plurality of force sensors; and
a processor configured to read data from the one or more force sensors and display a measurement related to the grip strength of the patient.

14. The system of claim 13 , further comprising one or more motion sensors integrated with the injection device.

15. The system of claim 13 , further comprising a transmitter configured to transmit data to an external device.

16. The system of claim 13 , further comprising a display for displaying the measurement.

17. The system of claim 13 , wherein the processor is further configured to provide instructions to a user to perform one or more actions for detection by one or more of the force sensors.

18. The system of claim 17 , further comprising one or more indicators, wherein the processor is configured to provide instructions by activating one or more indicators.

19. The system of claim 18 , wherein the indicators comprise one or more of visible, audible, and haptic indicators.

20. The system of claim 17 , wherein the processor is configured to provide instructions in response to one or more of receipt of a user input, receipt of a signal from an external device, a predefined time schedule, or an injection event.
