A patient medication use compliance aid which enables the users to readily ascertain the time at which they took a previous dose of medication. A time keeping device is incorporated into a typical container for medicinal products without the need for complicated container construction or complex mechanical parts or expensive electronic circuitry. The time keeping device displays the time and day of the week when the container was last opened by the patient-user and continues to display the same, even after closing of the container, to serve as a reminder. The time keeping device may also be provided with settable alarms to visually or audibly alert the patient as to when the next dose is to be taken. The compliance aid device can be conveniently provided as a separate element or as part of the cap or cover of a container so that it may be adapted for use with standard containers and need not be integral with or part of a medication container as such but rather can be utilized as a reusable item with fresh containers.
A device for providing medication use information to aid in patient compliance with a medication use regimen involving dispensing of medication from a container comprising a time keeping means for keeping the correct time selected from the group consisting of minutes, hour, day, date, week and month, and, combinations thereof, the time keeping means including display means to indicate time, sensor means for sensing when a medication container has been opened or closed to dispense medication, and said signal sensing means providing a signal to the time keeping means in response thereto, and signal processing means within the time keeping means for receiving the signal from the sensor means and activating the display means to indicate the time of the signal, the signal processing means including means for maintaining such indication of the time of the signal until a further signal from the sensor means is received by which the patient-user is provided with an indication of the last time the container was opened or closed.
A device for providing medication use information to aid in patient compliance with a medication use regimen involving dispensing of medication from a container comprising a medication container cover, time keeping means for keeping the correct time selected from the group consisting of minutes, hour, day, date, week and month, and combinations thereof, located within the cover, the time keeping means including display means to indicate time, sensor means capable of sensing when the cover is removed or replaced on a medication container, the sensor means including at least two electrical contact means capable of forming an electrical circuit when contact is made therebetween, conductive means for contacting the electrical contact means in response to removal or replacement of the cover on the container, means for providing a signal to the time keeping means in response to completing or interrupting a circuit between the electrical contact means, processing means within the time keeping means for receiving the signal and activating the display means to indicate the time of the signal, the processing means including means to maintain such indication until a further such signal is received and provide the patient-user with an indicator of the last time the container cover was removed or replaced.
