More Information
Summary:Medication delivery devices are provided having a sensor in the form of a single- pole double-throw (SPDT) switch, a conversion control module that receives signals from the SPDT switch and generates an outputs a signal, and related power control circuitry. The SPDT switch may interact with a rotating component having a plurality of teeth that slide against the arm during dose delivery. Contact of an arm of the SPDT switch to a peak of a tooth places the SPDT switch in a set state, while lack of contact between the arm and the peak of the tooth places the SPDT switch in a reset state. The SPDT switch and SR logic switch may be used to sense dosage of medication delivered during dose delivery. The power control circuitry can include a sleep state the reduces battery drain during non-use, and a wakeup state that senses the administered dose.
