DESIGN CHALLENGE: ECG LIMB LEAD

Dr Rockey Prajapati is a Medical Officer at Nuwakot District Hospital. ECG machines are an essential piece of medical equipment for any hospital around the world, and are used to enable doctors to visualize heart activity, by detecting electrical activity within the heart and outputting it on a screen. ECG limb leads are clamped to a patient's wrists and ankles in order to detect heart activity. However, at Nuwakot District Hospital they are experiencing problems with their ECG limb leads, in that the plastic clamp that holds the sensors to the skin keeps breaking whilst in use. 

PROBLEM DESCRIPTION

The white plastic clip holding the two halves of the clamp together is a poor fit, and slides out of its seating whilst the clamp is in use causing the halves of the clamp to separate.

 

CAN YOU HELP?

We would like to develop an improved ECG clamp design that can be used with the existing sensors. Ideally this clamp should be:

  • 3D printable as a single item (not made up of multiple parts)

  • Similar dimen
    sions to the original part

  • Quick, easy and intuitive to use

  • Contain an appropriately placed hole such that existing sensors can be attached
