In the traditional concept, there are two ways of drug delivery, to give or have an acupuncture treatment and dai-pump. In fact, with the rapid development of science and technology, a new type of drug delivery technology is emerging in recent years, that is, needle-free drug delivery system.

     The needle-less injection system uses a mechanical device to generate an instantaneous pressure, which pushes the liquid through a needle-less injector through an ion converter and an automatic injection system to form a high-pressure body stream, diffuse directly through the skin to the subcutaneous tissue of the patient. In this process, by controlling the thrust, can control the depth of the injection body, without damaging the deep tissue, and the injection process is very short, about 0.01 seconds, compared with the nerve conduction signal 0.2 seconds, the patient self-perception of pain, the stimulus is small, so there is generally not as obvious as a needle syringe tingling sensation, at the same time, the drug can be injected in a specific range of diffuse distribution, more conducive to the absorption of the preparation. 

       Speaking of needle-free injection system, voice coil motor has been used in practical cases, voice coil motor-supported needle-free injection system is the use of voice coil motor technology to convert electrical energy into magnetic energy to generate high-speed airflow, the rapid delivery of drugs into the body. At the same time, voice coil motor needle-less injection system is very suitable for injection of higher volume and greater viscosity of biological drugs, it can be used in patients with Crohn's disease, ulcerative colitis, atopic dermatitis, multiple sclerosis, etc. who need regular injections. 

        For more than 10 years, Kunshan Tongmao Electronics Co. , Ltd. has been deeply engaged in the field of voice coil motors. The voice coil motors are characterized by simple structure, high frequency, fast response, high speed, zero hysteresis and long life, tong Mau teamed up with other companies to develop needle-free drug delivery systems, and Tong Mau was responsible for developing voice coil motors for needle-free drug delivery systems.
