To design and produce serial shock tubes and further examine their application to experimental studies on blast injury.
Bio-medical engineering technique was used for the design and development of the serial shock tubes. One thousand four hundred and fifty nine animals (757 rats, 105 guinea pigs, 335 rabbits, 240 dogs and 22 sheep) were then used to test the wounding effects of the shock tubes.
Three types of bio-shock tubes, that is, large-, medium- and small-scale shock tubes were made in our laboratory. The large-scale shock tube is 39 meters long; the inner diameter of the test section is 1 meter; and the maximum overpressure in the driving section is 10.3 MPa. A negative pressure could be formed by means of the reflected rarefactive wave produced by the end plate. The medium-scale shock tube is 34.5 meters long; the maximum overpressure in the driving section is 22 MPa; the test section is designed to be a knockdown, showing 5 basic types with inner diameter of 77 to 600 millimeters, which could be used for researches on overpressure, explosive decompression, underwater explosion, and so on. The small-scale shock tube is 0.5 meter long with the maximum endured overpressure of 68.6 MPa. Results from animal experiments showed that this set of shock tubes could induce various degrees of systemic or local blast injury in large or small animals.
This set of bio-shock tubes can approximately simulate typical explosive wave produced by nuclear or charge explosion, and inflict various degrees of blast injury characterized by stability and reproducibility. Therefore, they can meet the needs of blast research on large and small animals.
设计并制造系列激波管，并进一步研究其在爆炸伤实验研究中的应用。
采用生物医学工程技术设计并研制系列激波管。随后使用1459只动物（757只大鼠、105只豚鼠、335只兔子、240只狗和22只绵羊）来测试激波管的致伤效果。
在本实验室制造了三种类型的生物激波管，即大型、中型和小型激波管。大型激波管长39米；试验段内径1米；驱动段最大超压为10.3兆帕。通过端板产生的反射稀疏波可形成负压。中型激波管长34.5米；驱动段最大超压为22兆帕；试验段设计为可拆卸式，有5种基本类型，内径为77至600毫米，可用于超压、爆炸减压、水下爆炸等研究。小型激波管长0.5米，最大耐受超压为68.6兆帕。动物实验结果表明，该系列激波管可在大小动物中诱发不同程度的全身或局部爆炸伤。
该系列生物激波管可近似模拟核爆炸或装药爆炸产生的典型爆炸波，并造成具有稳定性和可重复性的不同程度的爆炸伤。因此，它们能够满足大小动物爆炸伤研究的需求。
