A continuous arterial blood glucose monitoring device and a control method thereof

Abstract

The invention discloses a continuous arterial blood glucose monitoring device and a control method thereof, belonging to the technical field of medical instruments and methods. By using the three-wayconnection, a pressure tube, a blood collection port, an arterial catheter and other devices of the original arterial pressure measuring monitor, several groups of conductors of continuous arterial blood glucose meter are controlled by program to turn on and off the corresponding device for realizing actions of switching, opening / closing, pinching, rotating, so that the truncation of the anticoagulant saline in the arterial pressure measurement process is sequentially realized, the program-controlled integrated acquisition syringe sucks the liquid in the arterial catheter to realize the program-controlled elevation of the blood surface, The electric clip clamps the small-scale integrated syringe for blood collection and testing, and records, stores and analyzes all kinds of data through the blood glucose meter, at the same time transmits to the outside world and realizes the alarm function, which can greatly reduce the workload of the medical staff and improve the accuracy and effect of blood glucose monitoring at the same time. The invention has the advantages of exquisite thinking, good modularization, strong anti-interference, low cost, easy program control, easy expansion of function and high blood sugar monitoring accuracy.

Description

technical field [0001] The invention belongs to the technical field of medical and health equipment and methods, and in particular relates to a continuous arterial blood sugar monitoring device and a control method thereof. Background technique [0002] Normal blood sugar levels are necessary for the body to maintain physiological functions. However, in the state of emergency and critical illness, patients often experience transient increases in blood sugar due to critical illness and pancreatic islet dysfunction, which is called stress hyperglycemia. Stress hyperglycemia Hyperglycemia was defined as an increase in blood glucose exceeding 11.1 mmol / L in case of acute illness. Studies have shown that the incidence of hyperglycemia in ICU patients is as high as 8O%. It is now accepted that stress hyperglycemia may be the greatest risk factor for increased morbidity and mortality in ICU patients (reference: McDonnell ME, Umpierrez GE. Insulin therapy for the management of hype...

Problems solved by technology

At present, domestic non-invasive and minimally invasive blood glucose monitoring equipment cannot meet the high-precision and real-time requirements (reference: Li Hang, Research on infrared non-invasive blood glucose detection [D], master's degree thesis of University of Electronic Science and Technology of China, Chengdu, 2016.), and it has not met Non-long-term detection, high-precision continuous blood glucose monitoring equipment used by ICU patients

In 2018, the American media mentioned that the "secret team" of Apple's bioengineers is building a non-invasive sensor for the Apple Watch that can continuously monitor blood sugar levels. To a large extent, it is also difficult to meet the special requirements of high real-time and high precision of critically ill patients
