Problem being addressed[edit]

Newborn mortality accounts for over half of all infant deaths. In developing countries, where giving birth at home is common, there may be a lack of electricity to support delivery. Hand cranked heart rate monitors are more suitable for rural settings than expensive Western-derived equipment which can be difficult to repair and often rely on replaceable batteries. Discovering lowered heart rate during contractions gives medical workers a chance to suspend delivery, try to get more sophisticated medical assistance, and protect the well being of the mother and infant.

Detailed description of the solution[edit]

This device measures the infant’s heart rate during birth. The design includes an obstetrics ultrasound device connected to the main unit by a cord. It also contains a power-management electronic module, a sound amplifier and a crank for winding up the device. This robust design is meant to withstand wear and tear. Cranking its onboard power-supply charger for one minute provides 10 minutes of operation.

Designed by[edit]

  • Designed by: Philip Goodwin (industrial designer), Stefan Zwahlen (electronics designer) and John Hutchinson (project leader) in Cape Town, South Africa.
  • Manufacturing: This device is manufactured by Ultrasound Technologies Ltd in Caldicot, South Wales, United Kingdom. Website available here.

When and where it was tested/implemented[edit]
