Problem being addressed[edit | edit source]

Postpartum hemorrhage is one of the leading causes of maternal mortality in low-resource settings. The CAPP (Tire/Pressure Circumferential Abdominal-Pelvic Pressure) device is a simple contraption made of basic, local materials such as bike tires that aims to control postpartum hemorrhage by reducing blood flow to the pelvic organs.

Detailed description of the solution[edit | edit source]

The CAPP device consists of three mountain bike tubes that are tied around a woman's waist and legs and function to restrict blood from flowing to the uterus of the hemorrhaging woman. One tube is placed around each leg and one on the lower abdomen/pelvic area. Each tube is then secured tightly with sheets. A bike pump is used to inflate the tire tubes, which apply direct pressure to restrict blood flow to the pelvic area.

Describe its relevance for resource-constrained settings[edit | edit source]

The CAPP device is especially useful in low-income, resource-constrained settings for several reasons. It is comprised of rudimentary materials such as a bike pump, bicycle inner tubes, and sheets that can be easily obtained. It does not rely upon an electrical source. It is also inexpensive, portable, and highly effective.
