  • Patent number: 8663158
    Abstract: A method for tilling needleless injector capsules with liquid drug, whereby dissolved gas within the drug is replaced by a less soluble gas in order to reduce the inclusion of gas bubbles, or to prevent the growth of bubbles during storage and thereby prevent breakage of the capsules.
    Type: Grant

  • Publication number: 20130046233
    Abstract: A needleless injector has a syringe body having an opening at one end, a piston housed within the syringe body for urging a liquid within the syringe body through the opening and a ram for driving the piston. A shock absorbing component is provided for reducing an initial transfer of force from the ram to the piston. The initial rate of pressure increase on the liquid is reduced, thereby controlling the rate of collapse of gas bubbles in the liquid.

  • Patent number: 8287489
    Abstract: A needle-free injector device comprising a latch having a safe position which disables the triggering of the device, and a ready position which restrains movement of a dispensing member but enables triggering and a triggered position which permits movement of the dispensing member is disclosed. An additional safety mechanism blocks the triggering of the device until removed. A cap is provided to maintain the sterility and stability of the drug formulation and is configured such that the cap removal is required prior to placing the device in a ready to trigger state.

  • Patent number: 8267903
    Abstract: A casing for an injection device of the type having a safety device which prevents operation of the device, incorporating an actuator means by which the safety means of the device can be actuated to allow operation of the device. Also a casing for a medicament container having an opening closed prior to use by a break-off tip, having relatively moveable first and second casing parts, which on relative movement apply a breaking force to the break-off tip. A preferred embodiment includes both such features.

  • Patent number: 8066661
    Abstract: Formulations are described that are viscous and will benefit from needle-free delivery at high driving pressures. Conventional delivery of these viscous formulations by hypodermic syringes is inconvenient as well as painful. Formulations include those which have a viscosity of about 5 cS or more at about 20° C. and which can have 0.5 ml or more administered by a needle-free injector in about 0.1 second±0.02 seconds.

  • Patent number: 7901385
    Abstract: A casing (50) for an injection device (10) of the type having a safety device which prevents operation of the device (10), incorporating an actuator means (56) by which the safety means of the device (10) can be actuated to allow operation of the device (10). Also a casing (50) for a medicament container having an opening closed prior to use by a break-off tip (135), having relatively moveable first and second casing parts (51, 52), which on relative movement apply a breaking force to the break-off tip (135). A preferred embodiment includes both such features.

  • Patent number: 7320346
    Abstract: A method of proof testing glass containers is disclosed. The method involves applying pressure to a sealed container in two discrete stages as shown in FIG. 1. In the first stage, the pressure is increased to a peak over at a first rate. In the second stage, the pressure is reduced to zero at a much greater rate.
