Abstract

Dissertation for the candidate’s degree of technical sciences by speciality 05.11.17 – Biological and Medical Devices and Systems. – National Technical University "Kharkov Politechnical Institute", Kharkov, 2016. The work is dedicated to developing the methods and means of thermometry in order to increase the likelihood of diagnosing of female mammals reproductive function by temperature indicator. The physico-mathematical models of internal temperature distribution in the genital tract are built. Its accuracy and adequacy are valued on the example cattle females. Modeling results are allowed to determine the conditions for experimental research. Electrical analogy of heat conduction and electric model of the temperature gradient in the female genital tract are used for explanation of temperature difference changes. This paper shows the results of development and metrological attestation of portable device for measuring small changes of temperature with a resolution to hundredths of a degree units. Based on the model and experimental data was showed that the specified level of temperature difference in the vagina of females can be used as a threshold criterion for increasing the likelihood of sexual cycle phase and of ovulation determining. An automated implementation of diagnosis of the cycle phase and ovulation by temperature difference is considered.
