This Small Business Innovation Research (SBIR) Phase II project proposes to develop a cheap and novel needleless injector (NI) that uses a ceramic-based electrokinetic pumping mechanism together with suitable nozzle arrays. The Phase II effort will focus on building numerous prototype pump / nozzle systems and determining the ability to achieve performance adequate for subcutaneous and intramuscular injections. Models for predicting the temporal response of the pump / nozzle systems will also be refined and compared to experimental results.The commercial application of this project will be for delivering therapeutics such as vaccines and drugs for both human and veterinary markets. The ability to precisely control the injection temporal profile with the proposed device will enable injection site pain and trauma to be significantly reduced, thereby increasing effectiveness of NI drug delivery as well as reducing the probability of cross - contamination.

这个小型企业创新研究（SBIR）二期项目建议开发一种廉价且新颖的无针注射器（NI），该注射器使用基于陶瓷的电动泵送机构和合适的喷嘴阵列。第二阶段的工作将侧重于建立大量的泵/喷嘴系统原型，并确定实现皮下和肌肉注射的能力。用于预测泵/喷嘴系统的时间响应的模型也将得到改进，并与实验结果进行比较。该项目的商业应用将是为人类和兽医市场提供疫苗和药物等治疗方法。使用该装置精确控制注射时间剖面的能力将使注射部位的疼痛和创伤显著减少，从而提高NI药物递送的有效性，并减少交叉污染的可能性。
