I have read in the news today about a breakthrough in India that could benefit Africa and people with sickle cell (via BBC News.) The device " is a pulse oximeter, a non-invasive method of monitoring the oxygenation of haemoglobin using light. The patient is attached to the machine via a finger clip." You can measure a patient's level of haemeoglobin without requiring a needle. The costs of a machine should be between $200 and $300 for a hospital. This breakthrough should also greatly benefit Africa where sicke-cell anemia is the most widespread genetic disease, the difference between this device and the others that came before it, it that it caters to local needs and just because of that, it's a major plus.
