研制一种新型的、适用于中、小动物的迅速减压舱。通过138 次空载实验和36 例动物( 家兔) 实验发现:该装置的减压幅度和减压时间可调,减压幅度最大可达980665Pa,减压时间为7~336ms;减压时间与节流面积近似呈反比关系,与减压幅度呈“负相关”;减压精度较高,可产生不同程度的肺损伤,伤情重复性较好;能模拟多种迅速减压环境,尤其是减压速率很快的减压环境,可为冲击伤和减压损伤的发生机制及救治研究提供重要的致伤模型和实验手段。
Development of a new type of rapid decompression chamber suitable for medium and small animals. Through 138 no-load experiments and 36 animals (rabbits) experiments, it was found that the decompression amplitude and decompression time of the device can be adjusted, the maximum depressurization range is up to 980665Pa and the depressurization time is 7 ~ 336ms; Throttling area is approximately inversely proportional relationship, and the magnitude of decompression was “negatively correlated”; Decompression accuracy is higher, can produce different degrees of lung injury, injury repeatability is good; can simulate a variety of rapid decompression environment, especially Decompression rate decompression environment quickly, for the impact of injury and decompression injury mechanism and treatment of research to provide an important model of injury and experimental means.
