This is a disposable entry needle design, which is made up of three parts: the needle, the drug liquid and the paperboard that plays the role of the structure of cylinder. There is a tiny gap on the needle. When users use it up, the gap part will contact with skin cortex or blood and turn red, preventing the secondary use of the needle, reducing the spread of the virus, and ensuring the safety of the user's health. At the same time, the environmental protection of the structure has greatly reduced the cost, which can be provided to more patients who cannot afford the cost of the common syringes.
