Problem being addressed
Hypertension (also known as high blood pressure) continues to be a large problem globally. Blood pressure monitoring, however has changed little since it was first developed roughly a century ago. The traditional mercury sphygmomanometer is being phased out of use because of the toxicity of mercury. This has led to more widespread use of oscillometric, semi-automatic devices. Semi-automatic devices, however, still traditionally rely on batteries or an electrical connection in order to operate.
Detailed description of the solution
The Omron HEM-Solar fills the gap for an automated blood pressure monitor that can be easily used in rural setting. It does not require the training needed for the manual auscultatory method (using a mercury sphygmomanometer). The Omron HEM-Solar contains a solar panel that recharges the devices batteries allowing it to perform up to 300 readings without needing to be recharged.
Design and Manufacturing
- Designed and manufactured by: Omron Healthcare
When and where it was tested/implemented
- Testing: Field testing in Africa was published in June 2009.
- Implementation: This device is currently on the market, available online. Omron targets Europe, Middle-East and Africa. It is useful in all settings and has been tested specifically for use in low-resource settings.
