Alternative Communication Means are found in Alternative displays for Retrieval of Data from the Monitor This includes Retrieval of  Clinical Data on the Patient.

Multi-compartment Monitor

Yet another monitor design incorporates an array of compartments with each compartment holding a day's dose of medication. As shown in Figure 1, access to successive compartments can be controlled by a moveable cover which uncovers successive compartments, one at a time. The exploded view shows the cover belt which consists of a belt of cover material having a series of spaced holes. The cover belt is wound onto a supply reel when the monitor is filled and given to the patient.

The cover is moved by unwinding it incrementally from the supply reel and onto a take up reel. With each incremental movement, a dispensing opening moves over successive compartments in one row of  the array. When the dispensing hole has completely traversed the first row of compartments, a second hole begins traversing the second row of compartments, and so on until medication has been dispensed from all compartments.

Figure 1 shows several other components of the Multi- compartment Monitor: a cover grate which prevents the cover material from being lifted off of the array of compartments, a sprocket for moving the cover in the required increments, and a case. A gravity lock could also be incorporated into the mechanism so that after the cover had been moved one position, it could not be moved again until the monitor was inverted to assure that the medication had been removed.
Since this device does not protect the medication against moisture it would not be possible to use it with hygroscopic medications or preparations that include hygroscopic medications like ethambutol unless additional precautions are taken. The method described in Figure 1 and Paragraphs 2 and 3 in the section: Alternate Means of Achieving Moisture Protection may provide adequate moisture protection.

The multi-compartment monitor shown above is an adaptation of a commercially available device that utilizes standard electric power, not batteries. This commercially available device would be useful for treating TB in homes that have electricity.  The website is http://www.compumed.com.

There are several other companies that make medication monitors for use with standard electric power. Their website for one such company is    http://www.medreadyinc.com.
