Progress and Application of Bioelectrical Impedance Measurement Methods / 中国医疗器械杂志

The bioelectrical impedance measurement is a detection technique that uses the electrical characteristics and changes in human tissues and organs to detect biomedical information related to human physiological and pathological conditions. This article makes a comprehensive introduction from the aspects of impedance cardiography, electrical impedance respiratory monitoring, electrical impedance tomography, electrical impedance gastric dynamics detection technique, contact impedance and so on, as well as comprehensively introduces the progress and application status of bioelectrical impedance measurement methods.

Research of Perioperative Muscle Relaxant Monitor / 中国医疗器械杂志

Muscle relaxant monitor is a research hotspot in the field of clinical anesthesiology. According to the research status at home and abroad, combing the developing history of muscle relaxant monitor, detecting principle, a variety of electrical stimulation mode, and a variety of detection ways, this study reviews and analyzes the advantages and disadvantages of various testing methods and application status, provides technical research foundation for the degree of nerve block for quantitative assessment of muscle relaxant monitor instrument design. Meanwhile, we advocate that clinicians should use quantitative muscle relaxant monitor as much as possible in the perioperative period to reasonably guide the use of muscle relaxants so as to reduce the risk of complications caused by residual effects of muscle relaxants and provide more scientific and accurate digital guidance for assessing the degree of muscle relaxants of patients.

Development of a New Type of Atherosclerosis Detection Device / 中国医疗器械杂志

This paper describes how to develop a practical new type of atherosclerosis detection device, which can realize real-time measurement and analysis of human atherosclerosis. According to the mechanism of human atherosclerosis, the design objectives of the system are formulated to determine the construction of the platform. The system calculates the pulse wave velocity by measuring the pulse wave of human fingers and toes, adds four blood pressure measurements to the system design, calculates the ankle-brachial index, and comprehensively measures and analyses the degree of human arteriosclerosis.
