Case Study: Reusable ECG pads - Engineering World Health

—Glass bottles with bottle caps all have a thin plastic liners attached to the cap designed to seal the cap against the neck of the bottle. For these reusuable ECG pads, the liners are removed from the bottle caps and a small X is cut into the center of the liner. Then the head of a small metal clothing snap is inserted through the hole in the cap liner. —Disposable ECG pads means the number of test performed depends on availability of pads, with reusable pads made from readily accessible materials means more tests. —This simple device, forming a small disc with the flat part of the snap on one side of the plastic liner and the nub of the snap on the other side, can be attached to an ECG machine to produce a reliable medical test. The electrically conductive gel needed to attach the pad to the patient can be made from water, flour and salt.
