How do jet injectors achieve intradermal injections?
Depending on the device, the depth of a jet injection is determined by the pressure of the liquid stream, the diameter of the syringe orifice, or the distance of the orifice from the skin, as well as the user’s technique. Injecting into the thin dermal layer of the skin with a standard needle and syringe can be difficult; using a jet injector may make it easier for health care workers to deliver reliable intradermal injections.
