Design of first aid module in tent-form field medical system / 医疗卫生装备

Objective To design a multi-function first-aid module integrating instruments with the box to solve the existing problems in integration, operation, deployment, withdrawal, environmental adaptability and etc, so as to realize integrated storage, transport and operation of the instruments. Methods The module had its structure, modes of deployment and withdrawal, instruments buffering and vibration isolation, ergonomics and etc designed with the technologies of integrating box and instruments, integration, buffering and vibration isolation, centralized oxygen and power supply as well as the methods of system modeling,structure simulation and CAD.Results The first-aid module was gifted with the functions of respiratory and circulatory rehabilitation,vital signs monitoring,emergency treatment of complex and multi injuries, which could be used as a 2 000 mm×800 mm×600 mm emergency treatment platform when deployed. There were 4 angles for adjusting the backboard to form anti-shock positions for the severe casualties.The module had the time for deployment and withdrawal not more than 5 min,and was easy to deploy,withdraw,transport and store.Conclusion The module behaves well in structure,function,layout,operation and military service when used for the treatment of the severe casualties in the tent-form field medical system,which contributes to enhancing the casualty treatment efficiency and prognosis.[Chinese Medi-cal Equipment Journal,2018,39(5):12-16]

Research progress on identification of acute respiratory distress syndrome based on noninvasive parameters / 医疗卫生装备

The concept and pathogenesis of acute respiratory distress syndrome (ARDS)were introduced,and the methods for identifying ARDS based on noninvasive parameters in recent years were retrospectively reviewed including regression method, nonlinear fitting method and multi parameter method.The above methods had their advantages and disadvantages summarized. It's suggested that multi noninvasive parameters and machine learning algorithms such as neural network, support vector machine and decision tree be involved in model construction to promote PaO2/FiO2assessment based on noninvasive parameters,so that the rapid diagnosis and real-time monitoring of ARDS can be realized based on noninvasive parameters while there were no need for blood gas analysis.

Evaluation of multiple oxygenation indexes in acute respiratory distress syndrome / 军事医学

Acute respiratory distress syndrome(ARDS)and acute lung injury are grave syndromes associated with high morbidity of the mortality.Currently,the criteria for the classification of the severity of ARDS are the PaO 2/FiO2values, while OI,S/F and OSI values are also used as ancillary diagnostic and grading criteria for ARDS.In this review,we sum-marize the effects of four indicators on the diagnosis and severity of ARDS patients,their respective strengths and weaknes-ses,and predit the future development of the classification of severity of ARDS.

An area CCD-based detection system for up-converting phosphor immune lateral flow assay / 军事医学

Objective To make portable the detector for up-converting phosphor (UCP) immune lateral flow assay portable and increase the test precision by developing an area CCD-based detection system for UCP immune lateral flow assay.Methods The excitation light source was a 980 nm and 300 mW laser diode.In order to decrease the error induced by the un-uniformity of laser irradiation,a uniformity mirror was inserted in the beam and a calibration algorithm was optimized.The residual error from the un-uniformity irradiation was less than 1％.Results Thanks to the adjustability of the exposure time,the dynamic range of detection of the system was as high as 106 dB.The repeat test error for the very low signal was 1％ (variation coefficient).The linear correlation coefficient between the tested T/C value and sample concentration was 0.998.Conclusion Compared to is traditional instrument,this detection system is static,portable and highly precise.

The rescue of the hypothermic patients immersed by seawater / 医疗卫生装备

For the diathermancy of the seawater is much bigger than that of the air, and the heat dispersed from the body exceeds the heat produced by the body, the heat would be lost immediately when people fell into the cold seawater. The temperature of people would drop instantly to frozen stiff. So it has great signification to rescue the people dropped into the cold water at once. This paper will introduce how to rescue, examine, stabilize, insulate, finally transport the patient to the hospital, and some things that should be paid attention to during the whole process.
