摘　　要：目的 利用飞行生理参数记录检测仪监测舰艇在遭受水下非接触爆炸冲击时所受冲击力大小及爆炸前后舰员生理参数的变化,为在实船非接触爆炸试验中对舰员进行实时监测提供一种方法和技术手段.方法 利用飞行员飞行生理参数记录检测仪(又称BodyMonBelt生参仪),监测舰艇在遭受水下非接触爆炸冲击前后,处在舰艇不同位置的9名舰员的心电图、心率、呼吸率、体表温度及所受两轴向加速度值(Gz、Gy).统计爆炸点前后30 min内受试者的心率、呼吸率及体表温度变化,进行自身对比分析.结果 人体表心脏部位所受冲击Gz值为0.23～2.17 G、Gy值为-0.39～0.66 G,在人体可承受的冲击力范围内.爆炸前舰员最快心率107～171次/min,最快呼吸率22～29次/min;爆炸后最快心率113～155次/min,最快呼吸率24～33次/min;爆炸后30 min内平均心率和平均呼吸率均高于爆炸前,平均心率前后对比有统计学意义(t=2.929,P=0.019);体表温度无明显变化.结论 BodyMonBelt生参仪可准确记录爆炸试验过程中舰员所受冲击作用的强度,可同步记录舰员在此爆炸试验过程中的有关生理参数变化,是分析人体在危险试验过程中生理心理指标变化的有效监测设备.分析监测结果和比较,人体生理耐限值的结果表明,舰员通过穿戴防护装备和掌握正确防护姿势,可以有效防护本次当量级的冲击作用损伤.Objective To monitor the explosion impact and its influence to the shipboard personnnel's physiological state by BodyMonBelt-a biomedical monitoring equipment for aviation in the experiment of non-contact underwater explosion on warship and to promote a real-time monitoring technique. Methods In the experiment of non-contact underwater torpedo explosion on warship, 9 shipboard personnel and a manikin, who were in different locations, were monitored by BodyMonBelt. The recorded parameters included ECG, HR, respiratory rate, body temperature and bi-axial acceleration values (Gy and Gz), of which only accelerations were recorded on manikin. Several other BodyMonBelt devices were placed in different location for recording the explosive impact to ship body. Self-comparimn analysis on HR,respiratory rate and body temperature that measured in 30 min before and after explosion was taken.Results The acceleration range applied by explosion at heart position was respectively 0. 23-2. 17 G and -0. 39-0. 66 G along Gz and Gy axis and those were in endurable range of human body. The highest HR and respiratory rate prior to explosion could be in the ranges of 107-171 beats/min and 22-29 times/min and average HR and respiratory rate, gathered at 30 min after explosion, were higher than those before explosion (t=2.929, P=0.019). The body temperature had no significant change in experiment. Conclusions BodyMonBelt could accurately record the explosion impact that applied on ship body and shipboard personnel, and simultaneously monitor the related physiological changes. It would be an applicable equipment in analyzing physiological and psychological state of the people who works in hazardous environment. By analyzing the BodyMonBelt recorded results and comparing physiological tolerance limit, it is showed that wearing proper shield and maintaining right posture could effectively protect the shipboard personnel from the explosive impact at experiment equivalent grade.
