In many people’s minds, there are two ways to inject drugs, to give or have an acupuncture treatment and Dai pump, in fact, with the development of technology and progress, there has been a new type of drug delivery technology, namely needle-free injection drug delivery system. 

     A needle-free injection drug delivery system uses a mechanical device to generate instantaneous pressure by pushing the drug through a needle-free nozzle through an ion converter and an automatic drug delivery system to form a high-pressure body flow, through the skin and directly into the patient’s subcutaneous tissue. In this process, by controlling the thrust, the depth of the injection can be controlled, the deep tissue can not be damaged, and the injection process is very short, about 0.01 s, compared with 0.2 s of the nerve conduction signal, the patient has no pain and little stimulation, as a result, there is generally not as sharp as needle syringes, and the injection of drugs can be dispersed in a specific range, more conducive to the absorption of the preparation. Speaking of needle-free injection systems, voice coil motors have been used in the Houx injection system, which uses voice coil motor technology to convert electrical energy into magnetic energy to generate high-speed airflow to deliver medicine into the body quickly. Meanwhile, the voice coil motor needle-free injection system is ideal for injecting biopharmaceuticals with higher volume and viscosity, it can be used for patients with Crohn’s disease, ulcerative Colitis, atopic dermatitis, Rheumatoid Arthritis, multiple sclerosis, etc. who need regular injections. 

      Kunshan has been working in the field of voice coil motors for more than 10 years. The machine features simple structure, high frequency, fast response, high speed, zero hysteresis and long life, it is an excellent driving device for needle-free injection system.
