Color-changable Pin / Pin

The iatrical safety is a common problem all over the world, particularly, the problem of injector reuse. The “Color-changeable Pin” is a reliable and safe injector, which prevents reuse by changing the color of its pin. The operator and the sick can tell whether it can be used through the pin’s color, for example, the red color pin means danger and the blue one means safety.Traditionally, we justify the safety of the injector by its sealed plastic cover, which is not good enough. The “Color-changeable Pin” provides a direct identifying pattern by colors, which can not be converse. This makes it safer and more surefooted for the sick.
