The invention discloses medical equipment, and a non-invasive blood pressure measurement method and device based on PTT. The method comprises the following steps of: obtaining a first PTT characteristic value when the pressure of a cuff is 0 mmHg; controlling the pressure of the cuff to the target pressure; performing step type pressure relief on the cuff, and obtaining two or more second PTT characteristic values under different step pressures when the pressure is not 0 mmHg; and, obtaining the blood pressure value of a detected object according to the first PTT characteristic value and the two or more second PTT characteristic values. According to the method in the invention, in the process of measuring the blood pressure of the detected object, the first PTT characteristic value and thetwo or more second PTT characteristic values are obtained, so that the blood pressure value of the detected object can be obtained; operation is easy; implementation is easy; the reliability is high;furthermore, no special requirement for a measuring environment exists; and the method can adapt to different clinical environments.
Description
technical field [0001] The invention relates to the technical field of blood pressure measurement, in particular to a medical device and a PTT-based non-invasive blood pressure measurement method and device. Background technique [0002] When measuring blood pressure, non-invasive measurement is a very widely used method at present, the most common ones are auscultation and oscillometric method; what they have in common is: they all need to bind a cuff on the patient's arm, through the cuff The subject's blood pressure is indirectly obtained by pressurizing and depressurizing the belt. The difference is that the auscultation method is to obtain the blood pressure value by detecting the change of the sound, which is generally operated by professional medical personnel; while the oscillometric method is to indirectly obtain the blood pressure of the subject by detecting the pulse wave characteristics under different cuff pressures. , can be done automatically by the control u...
