    摘要: A valved container assembly comprising a container for containing a fluid, the container extending in an axial direction and having an open front end, a valve disposed in the container; and a plunger element disposed axially rearward of the valve. The plunger element is axially moveable in the container and a first volume is provided in the container between the plunger element and the valve, wherein the plunger element is configured to increase a pressure of the fluid in the first volume upon axial movement of the plunger element relative to the valve. The valve comprises a seal fluidly sealing the valve to an interior of the container along an entire perimeter of the valve, and a channel bypassing the seal, the channel having a first opening in fluid communication with an atmosphere outside of the valved container assembly and a second opening selectively sealed from the first volume by a resilient seal. The resilient seal is moveable between a sealing configuration and an open configuration to selectively seal the channel from the first volume, wherein in the sealing configuration the resilient seal fluidly seals against the container to fluidly seal the valve to the container so as to fluidly isolate the channel from the first volume, and in the open configuration the resilient seal does not fluidly seal against the container to fluidly seal the valve to the container so that the second opening of the channel is in fluid communication with the first volume. The resilient seal is moveable from the sealing configuration to the open configuration upon the pressure of the fluid in the first volume exceeding a first pressure threshold.

    摘要: A medicament delivery device has a syringe, a housing, a needle shield, a biasing member and one or more blocking members. The needle shield is biased axially forwardly by the biasing member so as to selectively cover a needle of the syringe. However, the biasing member is prevented from biasing the needle shield axially forwardly until a radial movement of the blocking members has occurred, which is precipitated by a forward axial movement of the syringe. Consequently, the forward movement of the syringe releases the needle shield to automatically make safe the device.

    摘要: An injection device having an outer housing configured to receive a syringe. The syringe has a barrel for containing medicament and a needle in fluid communication with the barrel. The device further has a needle shield axially moveable relative to the outer housing between a needle covering position and a needle exposing position and a biasing means to bias the needle shield axially forwardly toward the needle covering position. A locking sleeve, axially movable relative to the outer housing between a non-locking position and a locking position, selectively limits axial movement of the needle shield. In a first configuration, the needle shield is axially slideable within the locking sleeve to permit rearward axial movement of the needle shield from the needle covering position to the needle exposing position. In a subsequent configuration, the needle shield is prevented from moving axially rearwardly by interference with the locking sleeve, thereby maintaining the needle shield in the needle protecting position. The device may reduce the risk of needle stick injuries when compared to known injection devices and also may prevent unintentional re use of the device.

    摘要: A medicament delivery device (10) comprising a syringe (12) having a barrel with an open end, and an axially moveable stopper (18) received in the barrel separating a first chamber axially forwards of the stopper from a second chamber axially rearwards of the stopper. The medicament delivery device further including an expandable drive housing (24) arranged to receive a propellant from a propellant source (36) for providing a vapour pressure, the expandable drive housing having a narrow channel in fluid communication with the second chamber. The expandable drive housing is expandable upon receiving propellant from the propellant source and, upon expansion, causes forward axial movement of the syringe. Propellant introduced into the expandable housing may pass through the narrow channel into the second chamber and cause forward axial movement of the stopper in the barrel to expel medicament contained in the first chamber through the open end, where axial movement of the stopper in the barrel commences after axial movement of the syringe.

    摘要: Fluid delivery device for discharging a fluid, having: a housing; piston pump; biasing mechanism; and trigger mechanism. The housing has a basal end and a discharge end with outlet for discharging the fluid. The piston pump has a casing defining a pump chamber for storage of fluid, a piston slidably movable relative to the pump chamber, a piston plunger, and a delivery channel. The trigger mechanism is movable from a cocked configuration wherein the trigger mechanism prevents transfer of a biasing force of the biasing mechanism to the casing to a triggered configuration with the trigger mechanism enabling transfer of the biasing force to the casing to cause movement of the casing towards the housing outlet to discharge fluid from the pump chamber, along the delivery channel and out of the outlet of the housing. The biasing mechanism has one or more flexible catch members and a manually operable trigger.
