Abstract

A disposable, wearable, self-contained insulin dispensing device includes a housing and an insulin source in the housing that is connected to a catheter for injecting insulin into a user.

Claims

1. A medicine dispensing system, comprising:

a wearable pump housing assembly, the wearable pump housing assembly configured to house a medicine reservoir in an interior space such that the medicine reservoir extends in a longitudinal direction along a length of the wearable pump housing assembly;

a piston movably arranged in the housing assembly to dispense insulin from the medicine reservoir;

a drive system to advance the piston toward the medicine reservoir;

a bolus push button arranged on the wearable pump housing assembly so as to activate a bolus dispensing operation in which a bolus dosage of medicine is dispensed from the medicine reservoir;

a combined microphone and audio speaker arranged on the wearable pump housing assembly for recording audio and emitting sounds upon manipulation of the bolus push button; and

a control circuit in the pump housing assembly to communicate drive signals to the drive system to cause the dispensation of the insulin, the control circuit including;

a programmable unit that stores a programmed dosage schedule.

2. The medicine dispensing system of claim 1, further comprising:

a wireless communication receiver within the wearable pump housing assembly and in operative connection with the control circuit; and

a wireless controller to communicate signals to the control circuit in the pump housing assembly indicative of the programmed dosage schedule, wherein the wireless controller is configured to receive user input of glucose level measurements.

3. The medicine dispensing system of claim 2, wherein the wireless controller includes a user interface display screen.

4. The medicine dispensing system of claim 1, further comprising:

a recording and play back circuit operatively connected to the combined microphone and audio speaker such the recording and play back circuit is configured to, in conjunction with the combined microphone and audio speaker, record verbal messages and play back the verbal messages;

wherein the recording and play back circuit is arranged inside the wearable pump housing assembly.

5. The medicine dispensing system of claim 4, wherein the recording and play back circuit is in operative connection with the control circuit.

6. The medicine dispensing system of claim 5, wherein the recording and play back circuit is part of the control circuit.

7. The medicine dispensing system of claim 5, wherein the control circuit is configured to control operation of the drive system in response to signals received from the recording and play back circuit.

8. The medicine dispensing system of claim 4, wherein the recording and play back circuit is configured to record audio signals received by the combined microphone and audio speaker in response to manipulation of the bolus push button.

9. The medicine dispensing system of claim 8, wherein the recording and play back circuit is configured to store a time value in association with the recorded audio signals.

10. The medicine dispensing system of claim 4, wherein the recording and play back circuit is configured to cause the combined microphone and audio speaker to play verbal messages in response to manipulation of the bolus push button.

11. The medicine dispensing system of claim 10, wherein the verbal messages played by the combined microphone and audio speaker are verbal messages that had been previously recorded by the recording and play back circuit using the combined microphone and audio speaker.

12. The medicine dispensing system of claim 4, wherein the recording and play back circuit is configured to cause the combined microphone and audio speaker to play a verbal message at a predetermined time.

13. The medicine dispensing system of claim 12, wherein the verbal message is received from a remote audio input device.

14. The medicine dispensing system of claim 13, wherein the remote audio input device is a mobile telephone.

15. The medicine dispensing system of claim 1, wherein the control circuit is configured to control operation of the drive system in response to audio signals received by the combined microphone and audio speaker.

16. The medicine dispensing system of claim 1, wherein the control circuit is configured to cause the combined microphone and audio speaker to play verbal messages.

17. The medicine dispensing system of claim 16, wherein the control circuit causes the combined microphone and audio speaker to play the verbal messages in response to manipulation of the bolus button.

18. The medicine dispensing system of claim 16, wherein the control circuit causes the combined microphone and audio speaker to play the verbal messages in response to the occurrence of predetermined times associated with the verbal messages.

19. The medicine dispensing system of claim 16, wherein the control circuit causes the combined microphone and audio speaker to play the verbal messages in response to identification of a particular activity of the medicine dispensing system.

20. The medicine dispensing system of claim 1, further comprising:

a wireless controller to communicate signals to the control circuit in the pump housing assembly indicative of the programmed dosage schedule, wherein the wireless controller is configured to communicate with the control circuit via audio signals transmitted to and received from the combined microphone and audio speaker.
