NOW, PAINLESS INJECTION IS ALMOST A REALITY Scientists after very long research have almost succeeded in finding out a new technique of injecting flu shots, vaccines and other medications, without pain. Researchers led by Mi-ae Park et al, at Seoul National University in South Korea, claims that, this new device uses an erbium-doped yttrium aluminum garnet (Er:YAG, laser), to produce a small stream, accurate dose of liquid drug. It uses laser beam technique at lower energy to inject the drug painlessly. The jet of liquid medicine is slightly thicker than a human hair and ejects out at the speed of 100ft/ second. The pressure applied by the jet is slightly higher than the skin tensile strength. The microjet of liquid drug penetrates into the skin without splashing back. Although various studies were done using Piston-like microjet injectors, but it was very difficult to control the strength of the jet and dose of the drug. The latest laser-driven microjet injector can accurately control the depth that the drug has to penetrate and the dose of the medications.Initially the study was conducted on guinea pigs. The drug was injected up to few millimeters beneath the skin without any damage to the tissue. Now, scientists are working to develop a very low-cost replaceable micro-injectors for clinical use and soon will be used in the settings like mass vaccination of children. #Health #MedicalNews #HealthCareArticles #HealthUpdates medibiztv
