Injection videos

In these movies 0.15 mL saline is injected perpendicularly into the skin, on a regular 1.0 mL Luer-Lock syringes. Bella-mu 1.4 mm is placed loosely onto the skin of the deltoid area (the needle disappears in the skin), after which the liquid is injected. Intradermic injections can require a bit more injection pressure/force on the syringe than hypodermic injections, due to the elastic properties of the skin in which the liquid is injected. The formed bleb/wheal indicates a successful intradermal injection. All subjects have agreed to the publication of the below learning/instruction videos.
