Abstract

Systems, devices, and techniques are disclosed for administering and tracking medicine to patients and providing health management capabilities for patients and caregivers. In some aspects, a system includes an injection pen device including a dose setting mechanism, a dispensing mechanism, and an electronics unit to generate dose data associated with a dispensing event of a dose of the medicine dispensed from the injection pen device and time data associated with the dispensing event; a mobile device in wireless communication to receive and process the dose data; and a software application configured to determine a recommended dose based on health data and contextual data associated with a user of the injection pen device, the software application including a learning dose calculator module to adaptively calculate the recommended dose of the medicine based on time-relevant and circumstances-relevant data specific to the user of the injection pen device.

First claim

1 - 20 . (canceled)

21 . An injection pen device for administering medicine, comprising:
a dispensing mechanism configured to dispense medicine from the injection pen device; an encoder configured to generate an analog output signal in response to the dispensing mechanism dispensing the medicine; and a processor in communication with a memory, the memory storing a summation module, which when executed by the processor, causes the summation module to:
receive, as input, the analog output signal generated by the encoder;
determine a number of edges of the analog output signal;
determine a number of the edges of the analog output signal that are out of order; and
determine a direction of movement of the encoder based on a comparison between the determined number of edges and the determined number of edges that are out of order.

22 . The injection pen device according to claim 21 , wherein the summation module, when executed by the processor, is caused to determine the direction of movement of the encoder based on the determined number of edges that are out of order being below a threshold percentage of the determined number of edges.

23 . The injection pen device according to claim 22 , wherein the direction of movement is determined to be a forward direction of movement if the determined number of edges that are out of order is below about forty percent of the determined number of edges.

24 . The injection pen device according to claim 21 , wherein the memory stores a force pattern sequence module, which when executed by the processor, causes the force pattern sequence module, prior to the analog output signal being received by the summation module, to force at least one edge of the analog output signal generated by the encoder to conform to a pattern consistent with a forward direction of movement to determine a quantity of medicine dispensed by the dispensing mechanism.

25 . The injection pen device according to claim 24 , wherein the force pattern sequence module, when executed by the processor, is configured to correct an error in the analog output signal generated by the encoder.

26 . The injection pen device according to claim 21 , wherein the memory stores an asymmetric digital filter, which when executed by the processor, receives the analog output signal from the encoder and, in response to receiving the analog output signal, outputs a filtered digital signal.

27 . The injection pen device according to claim 21 , wherein the encoder is a rotary encoder including a rotatable plate configured to rotate relative to a stationary plate.

28 . The injection pen device according to claim 21 , wherein the processor is configured to generate dose data associated with a dispensing of the medicine and communicate the dose data to a mobile communication device in communication with the injection pen device.

29 . The injection pen device according to claim 28 , wherein the injection pen device is configured to communicate with a mobile communication device, the mobile communication device including a software application configured to determine a recommended dose of the medicine based at least in part on the dose data communicated from the injection pen device.

30 . A medicine administering system, comprising:
an injection pen device configured to dispense medicine, the injection pen device including an encoder configured to generate an analog output signal in response to the injection pen device dispensing medicine; and a software application configured to be installed on a mobile communication device, the mobile communication device configured to communicate with the injection pen device, the software application including a summation module configured to:
receive, as input, the analog output signal generated by the encoder;
determine a number of edges of the analog output signal;
determine a number of the edges of the analog output signal that are out of order; and
determine a direction of movement of the encoder based on a comparison between the determined number of edges and the determined number of edges that are out of order.

31 . The medicine administering system according to claim 30 , wherein the summation module is configured to determine the direction of movement of the encoder based on the determined number of edges that are out of order being below a threshold percentage of the determined number of edges.

32 . The medicine administering system according to claim 31 , wherein the direction of movement is determined to be a forward direction of movement if the determined number of edges that are out of order is below about forty percent of the determined number of edges

33 . The medicine administering system according to claim 30 , wherein the software application includes a force pattern sequence module configured to apply an algorithm that forces at least one edge of the analog output signal generated by the encoder to conform to a pattern consistent with a forward direction of movement to determine a quantity of medicine dispensed by the injection pen device.

34 . The medicine administering system according to claim 33 , wherein the force pattern sequence module, when executed by the processor, is configured to correct an error in the analog output signal generated by the encoder.

35 . The medicine administering system according to claim 30 , wherein the injection pen device includes a processor configured to generate dose data associated with a dispensing of the medicine and communicate the dose data to the software application.

36 . The medicine administering system according to claim 35 , wherein the software application is configured to calculate a recommended dose of medicine based at least in part on the dose data communicated from the injection pen device.

37 . The medicine administering system according to claim 36 , wherein the software application is configured to display the recommended dose of medicine on a display screen of a mobile communication device.

38 . The medicine administering system according to claim 36 , wherein the software application is configured to communicate the recommended dose of medicine to the injection pen device for displaying on a display of the injection pen device.

39 . The medicine administering system according to claim 30 , wherein the encoder is a rotary encoder including a rotatable plate configured to rotate relative to a stationary plate.

40 . A medicine administering system, comprising:
a software application configured to be installed on a mobile communication device; a medicine administering device configured to dispense medicine, the medicine administering device including:
an encoder configured to generate an analog output signal in response to the medicine administering device dispensing medicine; and
a processor in communication with a memory; and
a summation module executable by one of the processor or the software application to cause the summation module to:
determine a number of edges of the analog output signal;
determine a number of the edges of the analog output signal that are out of order, and
determine a direction of movement of the encoder based on a comparison between the determined number of edges and the determined number of edges that are out of order.
