이러한 무바늘 주사장치는 환자의 피하 조직내에 유체약물을 투여하기 위하여 환자 피부에 접촉하고 특정버튼을 작동시키면 예압된 압력이 팽창하여 피하주사 노즐을 통해 피부를 관통시킴과 동시에 유체약물을 피부 조직내로 주입하게 된다.The needleless injection device is in contact with the patient's skin to operate the fluid drug in the patient's subcutaneous tissue, and when a specific button is activated, the preloaded pressure expands to penetrate the skin through the subcutaneous injection nozzle and simultaneously introduce the fluid drug into the skin tissue. Will be injected.
