Abstract:
The concentration of hemoglobin in the blood is an important physical
condition parameter and a low level of hemoglobin in the blood is called
anemia, as the World Health Organization has determined the level of
normal hemoglobin concentration for people on the basis of age, sex and
pregnancy status. One of the most common causes of anemia is nutritional
deficiencies, especially iron deficiency, although deficiencies of folic acid,
vitamin B12 and vitamin A are also important causes. Anemia may cause
several diseases, including infectious diseases such as malaria, tuberculosis,
HIV and infection parasitic.
Our goal in this project is to design a device to detect the presence of anemia
in a non-surgical way, as this disease has become widely spread throughout
the world and the World Health Organization has revealed that there are
more than 1.6 billion people suffering from anemia, and that 42% of
children under 5 years of age and 40% of pregnant women worldwide suffer
from anemia.
This device aims to reduce infections that can spread due to the use of
needles and also reduce pain, and may be needed for patients in emergency
rooms, intensive care units and postoperative follow-up, in addition to the
person's ability to use this device at home and without the need to specialists
or doctors, which in turn makes it easy and inexpensive to follow up on the
condition of the affected person on a continuous basis.
The design of this device requires a source to produce light with
wavelengths of 940 nanometers (infrared), 650 nanometers (red), which are
harmless to humans. On the opposite side of the source is the detector, which
picks up the waves that pass through the finger. Then the captured waves are
processed and the results are displayed on the screen.
