ECG Limb Lead - improved connector

An ECG machine is a common piece of equipment in hospitals, giving doctors a visual trace of the electrical signals from a patient's heart. To read these signals, sensors are attached to the patients's ankles and wrists using an ECG limb lead, which uses a plastic clamp to secure the sensor to the desired part of the body.

This part had been printed and tested in Nepal, where a group of doctors were becoming frustrated with a poor design of ECG limb lead, where the plastic clamp kept falling apart. This was due to a connector between the two halves of the clamp which did not fit correctly. Here is our improved design, which forms a very snug fit.

Thank you to Humanitarian Makers, Tho X. Bui and Ross Michaels, for their contributions to this design.
