Microcirculation pulse flow monitoring system and method for fluid therapy, volume management

Abstract

The invention discloses a microcirculation pulse blood flow monitoring system and method for fluid therapy and volume management, belonging to the technical field of medical monitoring. The monitoring system of the present invention includes: a data acquisition module, a storage module and a comparison module. The present invention repeatedly locates capillaries in the same monitoring area at different times, collects and stores blood vessel image data; compares the measurement data of blood vessel images collected at different times, and uses the number of blood vessels that generate pulsed blood flow and / or the speed of pulsed blood flow And / or the frequency of pulse blood flow, etc., are used as indicators for accurate volume management and fluid therapy, which solves the problem of lack of clinical gold indicators for fluid therapy and volume management. The invention avoids heart failure, pulmonary edema and tissue edema caused by excessive infusion, reduces the burden on the kidneys, reduces infusion time, treatment cost and patient pain.

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 treatment in the per...

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
