Microcirculation pulse blood flow monitoring system and method used for liquid therapy and capacity management

Abstract

The invention discloses a microcirculation pulse blood flow monitoring system and method used for liquid therapy and capacity management, and belongs to the technical field of medical treatment monitoring. The monitoring system comprises a data collecting module, a storage module and a comparison module. At different times, repeated positioning is conducted on blood capillaries in the same monitored region, and blood vessel image data is collected and stored; the measurement data of blood vessel images collected at different times are compared, the number of blood vessels where pulse blood flow occurs and/or the speed of pulse blood flow and/or the frequency of pulse blood flow occurrence are used as indexes for making capacity management and liquid therapy accurate, and the problem is solved that liquid therapy and capacity management lack clinical golden indexes. Through the monitoring system, a heart failure, pulmonary edema and tissue edema of lungs caused by excessive transfusionare avoided, the burden of kidneys is reduced, transfusion time is shortened, treatment costs are lowered, and the pains of patients are relieved.

Description

technical field [0001] The invention relates to a microcirculation monitoring system, which belongs to the technical field of medical monitoring. Background technique [0002] Problem statement: During the anesthesia process during surgery, especially after general anesthesia muscle relaxation, blood pressure usually drops. Therefore, in order to prevent excessive blood pressure drop, anesthesiologists usually perform fluid expansion after anesthesia to maintain normal blood pressure. Also in the field of intensive care and emergency medicine, when rescuing critically ill patients, infusions are also required to improve blood volume and tissue microperfusion (fluid therapy). In fact, the ultimate goal of fluid therapy and volume management is to avoid occult hypovolemia and tissue hypoperfusion caused by insufficient fluid infusion, while preventing heart failure and tissue edema caused by excessive fluid infusion. [0003] Fluid therapy is an important perioperative treatm...

Problems solved by technology

[0015] At present, the microcirculation indicators commonly used in the world and in China mainly measure the state of microcirculation based on the vascular density of capillaries, the basic blood flow velocity driven by arteriovenous pressure difference, and the shape of blood vessels. The sensitivity of these indicators is still insufficient. In the process of diagnosis and treatment of acute diseases, it is not possible to better predict the condition in advance
