A New Method on Detecting the Process of the Blood Plasma Coagulation
Original Abstract
Abstract
Currently, in the researches and applications of the piezoelectric crystal sensors, many phenomenons have been found which can not be explained and consistent to the classical Sauerbrey theory based on the “mass respones”. And scholars often explained those phenomenons with “the non-mass response of the piezoelectric crystal”. In our researches, we improved the detecting equipments and obtained some primary experimental results. The results showed that the non-mass respones are independent of the piezoelectric sensor, but dependent on the characteristics of the liquor itself. Based on these results, it can be deduced that it is a new physical phenomenon, that is to say, the liquor has the electrical resonance characteristic which likes the characteristic of the piezoelectric crystal, and we can identify the characteristic of the liquor using the liquor’s frequency of the electrical resonance. Contrarily, as soon as any of the characteristics of the liquor changed such as component or viscosity, the resonance frequency will changed accordingly. Using the new detecting method grounded on the principle of the liquor resonance, the detection of blood coagulation is introduced in this paper. In the process of blood coagulation, the viscosity of the blood plasma was changed continuously resulting in the sequential change of the electrical resonance frequency. Therefore, it can reflect the process of blood coagulation by measuring the electrical resonance frequency.
