Abstract:David Fernandez Rivas developed a new technology for needle free injection. With this technology, he wants to participate in the needle free injector market. The assignment is to design a needle free injector for either vaccines, insulin or pigmentation. Injecting needle free is done by shooting liquid at a high velocity as a thin jet that creates its own needle to penetrate the skin. This new technology works with a laser that beams in the liquid, which causes a bubble to grow. This bubble creates so much pressure that the liquid will leave the chamber via a narrow channel, which causes a high velocity jet. The pigmentation application has been chosen for further development. So the injector is going to be a needle free injector for tattooing. The focus is not on the ordinary tattoo industry, but on the Permanent Make Up industry. This is a specialized type of tattooing of the eyebrows, eyelids, lips and also scarring and nipple areolas. In case of scarring and nipple areolas, the tattoo is meant as repigmentation of the skin. Needle free tattoo machines do not exist yet, so this could be a very interesting new product for the industry. Needle free injectors for vaccine, anaesthetic or insulin delivery do exist, but are somehow not well known. The final concept is based on a pen, since the intention is to draw on the skin. The ink will be inside a cartridge, which is inserted in the injector. The injector will be wireless, by using battery power and Bluetooth connection with a control panel. The concept uses a foot pedal for shooting the ink jets. After performing a user test, it became clear that the design needs some modifications.
