Figure 1.

Panel A shows the components of the MERM module and its location in the container in which the medication blister cards are stored. As seen in Panel B, the MERM module is removable for discrete transportation by the patient and to facilitate data download and battery replacement, if needed. There is ample flat ‘billboard’ space inside the medication container as well as on the top of the container that can be used for patient instruction labels, as shown in Panel C. The translation of the Chinese characters in the LED label are: “Take dose now”, “refill medications”, and “low MERM battery”. The left pictogram for the Patient Instruction Label says “please take_X_pills (how many pills) per day” and the right pictogram says “please collect sputum and take the sputum container to the hospital on_(agreed date)”. As also shown in Panels A, B, and D, holes in the container match the locations of the three lights on the MERM (the green dose alert light, the yellow medication refill light, and the red low battery warning light). In addition to the green dose alert light, an audible reminder tone sounds as another dose alert.
