Haemoglobin

Haemoglobin Meter

The Elcomatic Haemoglobin Meter is the latest development in a range of instruments designed for use in environments where access to power sources and laboratory facilities is severely restricted. The low cost battery operated instrument incorporates sophisticated electronics to provide essential diagnostic information at the touch of a button reducing the measurement cycle to less than ten seconds.

Designed primarily for use in developing countries the unit is supplied with a range of accessories which includes a mains battery charger or optional solar panel, reusable cuvettes and all materials necessary to prepare lyssed blood samples.

The cuvettes, specially designed for use with the Elcomatic Haemoglobin Meter, are easily cleaned thus removing the need for a continuous supply of expensive disposables

Haemoglobin

Haemoglobin is an iron-containing protein found in red blood cells. It enables the red cells to carry oxygen from the lungs to the rest of the body and carry carbon dioxide back.

The haemoglobin level indicates the blood's oxygen-carrying capacity and can play a major role in the early diagnosis of many illnesses such as Thalassemia, Sickle cell anemia, Leukemia, Malaria and Hook worm.

Principle of Operation

The meter uses a photometric method to determine the haemoglobin concentration in the sample. The principle has been used for haemoglobin detection by sophisticated laboratory analysis equipment for many years and is a well established technique.Using state of the art L.E.D. technology the meter produces three distinct wavelengths of light each of which is projected through the sample and measured by a sensitive photovoltaic cell.

A microprocessor compares these values against stored measurements obtained from a "reference" cuvette during the zero/calibration procedure and calculates the percentage transmission at each wavelength. These are used in a mathematical model to determine the haemoglobin concentration. This is then displayed on the L.C.D. panel.

Battery Operation

Using sophisticated electronics and power management software the meter is capable of processing over 100 samples from a fully charged battery. In addition the exceptionally low standby current required means the unit can be charged days or even weeks before use without the battery being discharged. This removes the need to have the unit continually charging and extends battery life.
