Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] Fig. 1 is the information flow chart of traditional auscultation method to measure blood pressure. Insert the stethoscope at the brachial artery under the cuff, first use an inflatable ball to inflate the cuff to exceed the systolic blood pressure of the subject, and then deflate it to decompress. During the decompression process, the measurer carefully captures the Korotkoff sound detected by the stethoscope, and at the same time observes the changing pressure value on the manometer. When the Korotkoff sound appears, the observed pressure value is recorded as the systolic pressure; the Korotkoff sound is represented by From weak to strong, from strong to weak, then from weak to strong, and then quickly turn to disappear, and the pressure value corresponding to the latter transition point, that is, "change of sound", is recorde...

Abstract

The invention relates to a method for measuring blood pressure with electrical korotkoff sound measuring assisted sphygmomanometer. The method comprises detecting korotkoff sound at the brachial artery with korotkoff sound probe and transporting the sound to a korotkoff sound controller through cable; recording, processing, and judging the korotkoff sound with the korotkoff sound controller, suggesting fetching systolic pressure and diastolic pressure by emitting rhythmic call isochronous with the pulse of the detectors according to medical diagnosis requirement (the first sound of the korotkoff sound and the last sound of the changed korotkoff sound); and fetching the systolic pressure at the first rhythmic call and diastolic pressure at the last rhythmic call. The invention strictly adopts korotkoff sound as detecting target for blood pressure measurement, can accurately and reliably transform weak korotkoff sound into isochronous rhythmic call hearable for human, and helps gauger fetch blood pressure measure value directly from matched pressometer, thereby realizing real electronization for measuring blood pressure with korotkoff sound.

Description

technical field [0001] The invention relates to the medical field of human blood pressure measurement, in particular to a method for measuring blood pressure with a Korotkoff sound electronic sphygmomanometer. Background technique [0002] After humans discovered blood pressure and its medical importance, they began to study and try a variety of blood pressure measurement methods. [0003] In 1896, the German pathologist Von Recklinghausen discovered that in the process of measuring blood pressure with the cuff inflated and deflated, as the external pressure drops, an oscillating wave will appear in the gas in the cuff , whose amplitude is related to the blood pressure of the human body. He believed that by measuring the amplitude of this oscillating wave, the systolic and diastolic blood pressure could be obtained through a certain conversion relationship, and he called this method the oscillometric method. But for a long time to come, the so-called conversion relationshi...
