摘要：
The utility model relates to the field of biomedical technology and, in particular, to devices designed to determine the dependence of sound parameters on temperature used in ultrasonic thermometry during the thermal ablation procedure, mainly of malignant neoplasms. The essence of the utility model consists in the fact that in the device for measuring the dependence of the speed of sound on temperature in samples of tissue-equivalent and biological materials containing a container for liquid, this container is made in the form of a shell with a closed volume, consisting of two equal parts, each of which is placed one of the elements of the acoustic cell, in addition to the latter, an additional acoustic cell is mounted in the shell, whose elements are installed with a gap relative to each other and placed in parts of the shell next to the elements of the main acoustic cell of the same name and parallel to them, each of the shell parts equipped with a fitting that, together with the cavity of the shell, provides a flow system for a thermostatically controlled fluid. In this case, the upper part of the shell is provided with a through hole for introducing a temperature sensor into the cavity of the shell. The technical result consists in the fact that the reference measurement and measurement of a sample of material are carried out simultaneously due to the parallel placement in the device shell of two acoustic cells, which significantly reduces the time of the study for one sample of material and, thus, increases the productivity of research work. 1 s.p. f-ly, 3 ill.Полезная модель относится к области биомедицинской техники и, в частности, к устройствам, предназначенным для определения зависимости параметров звука от температуры, используемой в ультразвуковой термометрии при осуществлении процедуры термической абляции, преимущественно, злокачественных новообразований.
