论文摘要
无针头喷射技术（NFIT）由于其优势引起了人们的注意。通过使用NFIT，它可以与常规针一样几次使用。而且，它使患者摆脱疼痛。由于喷射注射的NFIT是通过在高压下通过狭窄的孔口驱射液体药物来实现的，因此可以产生高速流体射流，可以容易地穿透皮肤和组织。直到最近，所有喷射器都使用了力和压力生成原则，这些原理以无调的方式进行注射，并有限地调节输送量和注入深度的能力。为了解决这些缺点，我们基于自定义的高速线性洛伦兹 - 力电机开发了可控的喷气喷射设备。使用此设备，我们能够连续监测和调节药物射流的速度，并准确调节注射过程中输送的药物量。
Needle-free injector technology (NFIT) has drawn attention due to their advantages. By using NFIT, it can be used several time unlike a conventional needle. Also, it makes patients free from pain. Since NFIT by jet injection is achieved by ejecting a liquid drug through a narrow orifice at high pressure, thereby creating a fine high-speed fluid jet that can readily penetrate skin and tissue. Until very recently, all jet injectors utilized force-and pressure-generating principles that progress injection in anuncontrolled mannerwith limited ability to regulate delivery volume and injection depth. In order to address these shortcomings, we have developed a controllable jet injection device, based on a custom high-stroke linear Lorentz-force motor. Using this device, we are able to monitor and modulate continuously the speed of the drug jet, and regulate precisely the volume of drug delivered during the injection process.
