【Abstract】 Objective: To provide theoretical basis for the applicability of the field transfusion pressurization device in the outdoor environment by comparing the performance parameters of the field transfusion pressurization devices and the existing similar products. Methods: Professional testing equipment were used to test the torsion of the pressure spring, the flow rate of liquid and the amount of residual liquid, the aging resistance and corrosion resistance of the device in high and low temperature environment drop, tensile strength and other performance indicators. At the same time, a parallel comparison test was carried out with the existing equipment to compare the technical parameters of the two. Results: The transfusion pressure device could obviously increase the flow rate of transfusion, and the pressure fluctuation was between the 7.92 to 8.12 kPa, so the pressure was relatively stable, with the characteristics of flexible withdrawal, corrosion resistance, high tensile and compressive strength, and basically no residue after transportation. Conclusion: The performance indexes of the compression device were obviously better than those of the existing products, and it was more suitable for the field transportation of the wounded.更多还原
