The needle-free insulin syringe is aimed at the water jet sprayed by the skin. The micro-hole at the front end of the ampoule is only 0.17 mm, and the micro-hole of the medicine liquid instantly penetrates the epidermal cells in the form of a "liquid needle", and penetrates into the subcutaneous tissue accurately and accurately to complete the injection. More comfortable and safer than puncturing the skin with a metal needle. Ideal for long-term insulin injections and elderly patients.

The emergence of the needle-free insulin injection system is an epoch-making revolution in the field of injection systems. It replaces the traditional syringe with a needle. It is safe and painless, prevents infection, and is convenient, simple and fast to use. The principle is that after the liquid medicine passes through a very fine hole through high pressure, a liquid column is generated, which penetrates the skin and is sprayed under the skin, so that the absorption effect is greatly improved. It is widely used in the injection of small amounts of liquid medicines such as insulin, interferon, and vaccines.

Insulin needle-free syringes have distinct and outstanding advantages:
1. Avoid needle eyes and pain: needle injection often touches the subcutaneous nerve and causes unbearable pain, and even the needle needs to be pulled out and repositioned. Patients who have been injected for a long time have difficulty finding a place without needle eyes to place the needle. Avoid all.
2. Avoid induration and edema: needle-free injection is mist-like high-speed spray, diffusion absorption, more efficient and uniform.
3. Prevent skin infection: No piercing of the skin ensures aseptic operation to a greater extent, so it will not cause infection.
4. The operation is simple and safe, the dosage is more accurate, and 0.01ml fine-tuning can be achieved. The needle-free insulin injector is aimed at the water jet of the skin, only 0.17 mm, like a "needle" made of water, which accurately enters the skin tissue and is very suitable for patients who have long-term insulin injections. This also marks that patients who have been injected for a long time have said goodbye to the painful era of acupuncture.

Patients who have been taking insulin for a long time need to have two or three injections a day. When the needle is pierced into the human body, it will cause split damage to tissue fibers and capillaries, resulting in pain, bleeding and infection, which will bring more psychological pressure and spirit to the patient. burden. In addition, the local induration caused by long-term injection makes it difficult for the drug to be absorbed and affects the curative effect.
