동물용 백신 무침 자동 주입 주사기 노즐(Jet Injector Nozzle)의 구동부 설계검토를 통한 노즐 및 목업 형상의 제안 = Proposal of Nozzle and Mockup Dhape through Design Review of Driving Part of Jet Injector Nozzle for Animal Vaccine-free Automatic Injection Syringe

다국어 초록 (Multilingual Abstract)

A needle-free automatic injection syringe is a device that delivers drugs into the skin and tissues using a high-speed fluid jet without using an injection needle. This technology is attracting attention as an efficient means of vaccine delivery in the veterinary and livestock fields that reduce the risk of cross-infection and require mass vaccination. In particular, animal vaccination provides various advantages over conventional needle injection methods in terms of worker safety, inoculation speed, and maintenance cost. This paper was conducted to solve the problem of pressure loss at the nozzle discharge side of the existing Jet Injector in designing the flow path of the animal vaccine-free automatic injection syringe nozzle. To this end, the flow rate of the air tank (receiver) was determined, the needleless injection was basically designed, and the simulation was performed to prove its validity. Through these series of processes, the design review of the driving part was completed, and through this, the nozzle and neck-up shape were proposed to obtain the desired performance. However, it is thought that more trial and error are needed to commercialize such a needleless injection to humans.
