Abstract

One example discloses a handheld medical device, comprising: a patient attribute sensor input configured to receive a patient attribute input signal; a dosage calculator configured to output a prescribed dosage volume output signal in response to the patient attribute input signal; a dosage volume sensor input configured to receive an actual dosage volume input signal; and a dosage comparator configured to generate a comparator output signal based on a comparison between the prescribed dosage volume output signal and the actual dosage volume input signal.

Claims

1. A handheld medical device, comprising:

a patient attribute sensor input configured to receive a patient attribute input signal;

a dosage calculator configured to output a prescribed dosage volume output signal in response to the patient attribute input signal;

a dosage volume sensor input configured to receive an actual dosage volume input signal; and

a dosage comparator configured to generate a comparator output signal based on a comparison between the prescribed dosage volume output signal and the actual dosage volume input signal.

2. The device of claim 1:

wherein the handheld medical device includes both a patient attribute sensor and a dosage injector.

3. The device of claim 2:

wherein the patient attribute input signal is a patient glucose level input signal; and

wherein the dosage injector is an insulin injector.

4. The device of claim 1, further comprising:

a patient attribute sensor configured to directly sense at least one of;

glucose;

a biomarker;

or a molecule.

5. The device of claim 1, further comprising a dosage device having:

a dose reservoir, for long term storage of a set of doses;

a dose chamber, coupled to the dose reservoir, for short term storage of one of the doses;

a dosage volume sensor, coupled to the dose chamber and configured to output the actual dosage volume input signal based on the one of the doses; and

an injector configured to administer the one of the doses.

6. The device of claim 5:

wherein the dosage volume sensor includes a set of capacitive electrodes configured to generate the actual dosage volume input signal.

7. The device of claim 5, wherein:

the dose chamber is a syringe; and

the injector is a needle.

8. The device of claim 1:

wherein the medical device is a single-use disposable device.

9. The device of claim 1:

wherein the comparator output signal is at least one of;

an alarm signal or a display signal.

10. The device of claim 9:

wherein the dosage comparator is configured to generate the comparator output signal if at least one of;

the actual dosage volume input signal is below the prescribed dosage volume output signal;

or the actual dosage volume input signal is above the prescribed dosage volume output signal.

11. The device of claim 1:

further comprising an output display coupled to receive the comparator output signal.

12. The device of claim 1:

wherein the medical device is remotely powered by at least one of;
