Needle-free injection as a new approach to percutaneous administration , injection traditional acupuncture drugs , compared to show its more attractive features , such as painless injection drug absorption rate, simple operation, no cross-infection I believe that with the jet theory and needle-free injection technology further mature and improve , needle-free injection will replace the traditional injection has become a universal drug injection . In order to promote the development and popularization of needle-free injection technology , a syringe without a needle to trigger use jet injection characteristics of the test evaluation is becoming increasingly important . Test can evaluate feedback syringe structural design optimization results and improve the overall performance of the syringe without a needle on the one hand ; the other hand, through the testing and evaluation of the syringe without a needle jet injection characteristics , will help ensure the quality and the establishment of the syringe without a needle syringe without a needle users' reputations, thus speeding up the needle-free injection technology to the public . Syringe without a needle mathematical model simulation analysis, the proposed syringe performance test methods and test system model ; conducted a test system in a test system based on the analysis of the model simulation , sensor and data acquisition card selection , the sensor is designed conditioning circuit, to complete the electronic structure part of the design of the test system ; for the diversity of the needleless syringe sizes , while taking into account the ease and convenience of the test operation , the mechanical structure of the testing system portion is designed to solve the parts of the installation of the entire test system ; using LabVIEW graphical programming language designed test system software part , and signal generator standard signal test system acquisition program and analysis show program . Finally, build a good no needle syringe test evaluation system easyJet syringe without a needle and independent design and manufacture of needle-free syringe trigger force test experimental jet impact experiments for various internal parameters of the syringe without a needle , evaluation of different parameters on the non- needle - syringe jet injector characteristics . The experiments show that the test system can trigger force jet impact test , and completed by the analysis of experimental data processing , testing and evaluation of the performance of existing syringe without a needle injection syringe without a needle .
