摘要：
A method for the non-intrusive measurement of blood pressure in a circuit of a dialysis machine, using a device provided with a sleeve forming a portion of the blood circuit and having at least one part which moves according to the pressure difference between the inside and the outside of the sleeve, and with an emitter and a receiver of electromagnetic waves. The method comprising the emission of a beam of electromagnetic waves and the receiving of a beam of electromagnetic waves reflected from the moving part, in order to measure the displacement of the moving part in such a way as to establish a relationship between the position of the moving part and the pressure of the blood circulating in the sleeve.
