Abstract

The invention is applicable to the technical field of medical monitoring, and provides a method and device for monitoring pulse blood volume parameters. The method comprises the following steps: obtaining at least two-way pulse wave signals at designated parts of a human body, wherein the at least two-way pulse wave signals correspond to at least two-way optical signals with different wavelengths; determining the pulse blood volume parameters according to the at least two-way pulse wave signals and a preset coefficient group. According to the invention, at least two-way pulse wave signals are analyzed and calculated, so that continuous monitoring on the pulse blood volume parameters is realized; at least two-way transmission light signals are obtained through enabling at least two-way light rays with different wavelengths to pass through the artery blood vessels of the designated parts of a human body, so that the at least two-way pulse wave signals are obtained; therefore, the impact of substances except hemoglobin on the measuring result is eliminated, and accurate measurement for the pulse blood volume parameters is realized.

Description

technical field [0001] The invention belongs to the technical field of medical monitoring, and in particular relates to a monitoring method and device for pulse blood volume parameters. Background technique [0002] The main function of blood circulation is to complete the material transport in the body, transport nutrients and oxygen to various tissues in the body, so as to participate in the metabolic activities of cells. Hemoglobin in red blood cells is the main carrier for transporting oxygen, and the amount of hemoglobin determines the oxygen transport capacity. The oxygen demand of the terminal tissues or organs of the human body (such as the head or fingers) is relatively high. If the oxygen supply capacity is insufficient and lower than the normal level, the metabolism of the tissues or organs will not be carried out normally, and these tissues or organs may be severely damaged. injury, even life-threatening. [0003] The body's oxygen supply level is determined by...
