液体喷射注射器机械性能评价试验

从喷射注射的穿透性能、喷射完全度和扩散性能三个角度出发，对研发的液体喷射注射器分别进行了穿透压强测试、对具有一定硬度不同厚度的硅胶进行喷射注射以及对一定硬度的凝胶进行喷射注射．并与国外同类产品进行了实验对比。测试实验表明，自制液体喷射注射器具有与国外同类产品相一致的机械性能．所构建的穿透性能、注射完全度和注射扩散度评价能反映液体喷射注射器注射的有效性。

The Evaluation of Mechanical Performance of a Jet Injection System

In this study, the mechanical properties of a self-made jet injector and a foreign product are tested from three aspects： penetration ability, injection completeness and injection dispersion. Correspondingly, three different experiments are designed and performed： dynamic pressure measurement, injection into silicon rubbers with fixed hardness yet different thickness and injection into polyacrylamide gels with fixed hardness. The results show similar mechanical properties between self-made system and the foreign system. The evaluation of the mechanical performance of jet injectors that consists of penetration ability, injection completeness and injection dispersion can describe the jet injection process effectively.
