Scientists at the Altai State Agrarian University have developed a device for rapid determination of bilirubin and hemoglobin concentration in animals without blood sampling.
The device is based on spectrophotometric analysis of backscattered light passing through the tissues of the eye or skin of the animal. This method allows for non-invasive measurements, reducing stress in animals during diagnosis.
Radiation is directed at the tissues at wavelengths of 460 and 550 nanometers, which corresponds to the absorption spectra of bilirubin and hemoglobin. Analysis of the reflected light provides high accuracy in determining these indicators without the need for skin puncture.
The device is equipped with a color sensor, a light ring, a data processing module, and a Bluetooth transmitter. The compactness and autonomous power supply allow the device to be used in mobile veterinary practice without connecting to stationary equipment.
A special feature of the design is the elastic corrugated cuff on the eyepiece, which ensures a tight fit to the surface, preventing extraneous light from entering. This contributes to the stability of measurements and minimal contact with the animal, which reduces discomfort.
The development is important for veterinary medicine, as it allows for quick and accurate diagnosis without invasive procedures. This improves the quality of animal care and reduces the risks associated with stress and trauma during traditional blood sampling methods.
