Cambridge Design Develops Device to Address Maternal Mortality Rates

Technology and design partner Cambridge Design Partnership has developed a medical device designed to help healthcare workers respond to life threatening situations experienced by mothers after childbirth, specifically in low resource settings.

Postpartum Haemorrhage (PPH) is the term given to severe bleeding within 24 hours of childbirth. It is the leading single cause of maternal mortality and is thought to be responsible for approximately 57,000 deaths each year worldwide, nearly all of which occur in developing regions, according to industry data . With the proper equipment deployed at the right time, PPH can be treated very effectively. In 2012, the World Health Organization (WHO)updated its recommendations to include a Uterine Balloon Tamponade (UBT) as a treatment for PPH when uterotonic drugs are ineffective or unavailable.

Commercially available UBTs can cost as much as $200 each and need to be carefully inserted in theatre by trained clinicians. These factors prohibit their use in low resource areas, where currently a makeshift alternative assembled by tying a condom to a urinary catheter – the ‘condom catheter’ – is being trialled, Cambridge Design executives claim. While this device is certainly cheaper, it still requires careful assembly, significant training and skill to be successful.

The new UBT designed by Cambridge Design Partnership bridges the gap between the more expensive versions used in the West and the ‘condom catheter’. Its novel design combines features that make it intuitive and effective to use, to enable patient safety even in the hands of less experienced users – as well as ensuring cost effectiveness for manufacture.

“To be effective in low resource settings, medical products such as UBTs must be affordable and available; optimized for the intended conditions of distribution, storage, and use. To meet these needs we applied a human centred approach to the innovation process – combining expertise in human factors, risk management and interaction design – to the development of our device,” said Lucy Sheldon, human centred design specialist at Cambridge Design Partnership. “Our aim was to maximize usability in the hands of minimally trained birth assistants and lower the overall costs of the intervention, through reducing the medical professionals, equipment and training required to safely and effectively use the device – to ultimately save lives.”

Cambridge Design Partnership currently is looking for partners and funding to continue the development of its UBT concept, to identify and test progressive training and deployment strategies potentially utilising mobile phones and to quantify the potential of a ‘reduced training’ UBT intervention.

Based in the United Kingdom, Cambridge Design Partnership is a technology and product design partner specializing in the healthcare, consumer, energy and industrial equipment markets.
