In step 950, the MCD Device 100 determines whether the patient has removed and taken one or more containers 160 corresponding to a dosage of medication for the date and time stored on the prescription schedule. If the MCD Device 100 determines that the medication has been removed, the process may proceed to step 970.
If the medication has not been removed, the process may proceed to step 960 the MCD Device 100 may issue an alert, after a predetermined time-out period, if the patient has not taken any steps to removed their medication after the initial alarm in step 930. In selected embodiments, a time-out period may be stored on the prescription schedule or the time-out period may be sent from the MCC Device 200. A time-out period may be between 5 seconds to 5 minutes. The time-out period may be 30 seconds. The MCD Device 100 may then return to step 940 to determine whether the patient has removed their medication after the alert in step 960. An alert may be sent to one or more of the MCC Device 200 and a MC Device 300 to notify a primary care provider, a homecare provider, and/or a family member that a dosage of the medication for the date and time stored on the prescription schedule has been missed.
In step 970, once it has been determined that the medication has been removed and taken by the patient, the MCD Device 100 may make a record of the action. The MCD Device 100 may store the record in the memory of the control unit 20. The MCD Device 100 may transmit the record to one or more of the MCC Device 200 and a MC Device 300 to provide confirmation and/or a record that the patient has taken their dosage of the medication for the date and time stored on the prescription schedule. The process may then return to step 900 where the MCD Device 100 may check, monitor, and/or proceed with a next medication dosage stored on the prescription schedule.
Turning to the interaction of a MCC Device 200 and a MCD Device 100 to allow a primary care provider to program or alter a prescription schedule, FIG. 10 depicts an exemplary prescription transmission process. In step 1000, the control unit 20 of a MCC Device 200 may establish a data connection with a MCD Device 100. In selected embodiments, each MCD Device 100 connected to the networks 500 may include a unique identifying serial number and/or may be associated with a unique username. A primary care provider or other authorized personnel may use a MCC Device 200 to initiate a connection with a specific MCD Device 100 based on one or more of the identifying serial number and username.
In step 1010, the MCC Device 200 may query the MCD Device 100 to retrieve a saved prescription schedule on the MCD Device 100. The MCC Device 200 may display contents of the prescription schedule including, but not limited to, the types of medication prescribed, the amount of medication prescribed, and the frequency or schedule in which the medication is to be taken by the patient.
In step 1020, the MCC Device 200 may query the MCD Device 100 to retrieve current and/or past health and vital signals transmitted to and stored on the MCD Device 100. The MCC Device 200 may then display the health and vital signals for the primary care provider to review.
In step 1030, the primary care provider may issue a new or replacement prescription schedule from the MCC Device 200 to the MCD Device 100. The new or replacement prescription schedule may replace the previously saved prescription schedule on the MCD Device 100. In select embodiments, the MCC Device 220 may generate the new or replacement prescription schedule, based on health and vital signals received from the MCD Device 100, and the MCC Device 220 may send the new or replacement prescription schedule to the MCD Device 100. The new or replacement prescription schedule may include a listing of dates and times corresponding to new dates and times that a patient is to take their dosage of the medication. The new or replacement schedule may include a new dosage amount of medication for dates and times previously stored on the then most recent prescription schedule, or include a new dosage amount of medication for new dates and times that a patient is to take their dosage of the medication. The new or replacement prescription schedule may include information regarding medication to be dispensed, information regarding a dosage size of medication, instructions on taking the medication, potential drug interaction warnings, and/or potential side effect warnings.
In step 1040, the primary care provider may send a message, send an alert, and/or initiate an audio and/or video connection from the MCC Device 200 to the MCD Device 100 to discuss changes with the patient or provide additional information to the patient regarding a new medication or a new prescription schedule. In selected embodiments, the protective covers 180, 185 may be locked to the housing 110 to prevent removal of containers 160 of medication from the MCD Device 100 at times other than during the dates and times of the prescription schedule. When a present date and time matches the prescription schedule, the MCD Device 100 may unlock one or more of the locking latches 181, 186 in order to allow the protective covers 180, 185 to be opened and containers 160 to be accessed. The locking latches 181, 186 may be opened at times not corresponding to the prescription schedule by entering an authorization code into the MCD Device 100, or by having the MCC Device 200 send an unlock command to the MCD Device 100. In one non-limiting example, a pharmacist may be able to enter an authorization code in order to open up the protective covers 180, 185 in order to refill a prescription for the MCD Device 100. In one non-limiting example, a doctor may be able to send an unlock command from the MCC Device 200 to the MCD Device 100 to open the protective covers 180, 185 in order for a pharmacist to refill a MCD Device 100, or if a patient using the MCD Device 100 needs to access an additional dosage of a prescription at a time other than one set by the prescription schedule.
In step 1050, the MCC Device 200 may terminate the connection with the specific MCD Device 100.
