Abstract:
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.
