The Need:

A problem facing much of the developing world is unreliable power grids. Power outages are common, but power surges cause the most damage to healthcare equipment. The issue is multiplied by many hospitals having older wiring, lack of grounding, and even the bypassing of integrated fuses due to lack of spares. The result is that parts of the powerboard or more sensitive components in the machine are ruined, requiring ordering of replacement parts that can cost hundreds of dollars and take months to arrive.

Some hospitals are able to add additional protection to machines, in the form of a electro-mechanical voltage regulator or a uninterruptible power supply. However these are complex, expensive and often break or need other service.

The Technology:

EWH is interested in developing a low-cost surge protection device that can provide precise, reliable protection for an individual device.

Specifications and Restrictions:

This device is for developmental purposes only and should not be used on any critical medical equipment.

Alert the user when a surge has been detected, and possibly have the ability to automatically re-set.
Connect in a way that is easy for untrained users to install, such as standard wall plugs.
Applicable to a wide range of devices: Centrifuge, patient monitor, small exam lights, etc….
