KMB28B型潜水装具模拟480m饱和-493m巡回潜水试验评价

Evaluation of KMB28B Diving Equipment in Simulated Heliox 480 m Saturation and- 493 m Excursion Dives

目的验证和评价KMB28B型潜水装具在480 m饱和-493 m巡回潜水实验中的安全性。方法 4名健康男性潜水员参加模拟480 m饱和-493 m巡回潜水实验,于255 m、486 m干舱停留阶段及493 m巡潜阶段使用KMB28型潜水装具,模拟中等劳动强度进行试验,测定每分钟耗气量。结果各阶段潜水员呼吸顺畅,无不适感觉,4名潜水员的平均耗气量最大为21.77 L/min,满足≤29 L/min的计算要求。结论 KMB28B型潜水装具的防护性能可应用于模拟480 m饱和-493 m巡回潜水。

Objective To validate and estimate the safety of KMB28 B diving equipment in the simulated heliox 480 m saturation and -493 m excursion dives. Methods Total four healthy male divers participated in the simulated heliox 480 m saturation -493 m excursion dive with KMB28 diving equipment. The gas consumption per minute of four divers, to performed the simulated moderate intensitiy labour, was measured in the 255 m, 486 m dry chamber and 493 m excursion dive thai. Results Total four divers felt breathing smooth, comfortbale, maximal gas consumption per minute was 21.77 L/min, under the calculated demand 29 L/min. Conclusion The KMB28B diving equipment can be used for 493 m excursion dive.
