    摘要： The invention provides a device which seeks to ensure that substantially all the particles delivered avoid interaction with the so-called “starting process”. There is provided a needleless injection device comprising a driver chamber (51) arranged, in use, to contain a charge of pressurised gas, a duct section (52) connected to the driver chamber (51) to receive gas therefrom and a closure means (53) for preventing the flow of gas from the driver chamber (51) to the duct section (52) until the closure means (53) is opened. Further, a dose of particles (58) is positioned within the device in the region of the closure means (53). The device is so constructed and arranged that upon opening of the closure means (53), a primary shock wave is produced to travel along the duct (52) in a downstream direction so that a substantially quasi-steady gas flow is established in the duct (52) upstream of the primary shock wave, with the dose of particles (58) being substantially wholly entrained in the substantially quasi-steady flow to be accelerated thereby and expelled from the device.

    摘要： A needleless syringe device for accelerating particles into a target tissue of a vertebrate subject is provided. The syringe features an elongate, tubular duct having a lumen for delivering the particles towards the target tissue. The duct may have a constant cross-sectional area. The device further features a receptacle holding the particles and a gas discharge chamber upstream of the receptacle. On actuation the gas discharge chamber discharges pressurised gas having a maximum total pressure of about 10 bar or less. Methods of using the device for delivering particles to a target tissue are also provided.
