Abstract: A drug delivery device includes a housing, a fluid reservoir received within the housing, a drive assembly configured to dispense fluid from the fluid reservoir, a needle hub actuator attached to the housing, and a needle hub at least partially received by the housing. The needle hub includes a hub body, a needle holder with a needle attached to the needle holder, and a cannula holder with a cannula attached to the cannula holder. The needle hub actuator is configured to move the needle holder and the cannula holder from a retracted position where the needle and the cannula are positioned within the hub body to an insertion position where the needle and the cannula are positioned within the hub body. The needle hub is detachable from the housing.

Abstract: A needle hub for a drug delivery device includes a needle holder and a needle attached to the needle holder, a needle actuation assembly configured to move the needle holder from a retracted position, to an insertion position, and back to the retracted position, and a pressure interlock comprising an inlet configured to be in fluid communication with a fluid source, an outlet in fluid communication with the needle, and a lock member. The lock member having a first position where the lock member prevents actuation of the needle actuation assembly and a second position where the lock member allows actuation of the needle actuation assembly. The lock member is moved from the first position to the second position based on a pressure within the pressure interlock.

Abstract: An aerosol generation device has a heating chamber into which an aerosol substrate is insertable for being heated to generate an aerosol. The heating chamber is housed in a casing and an aperture is provided, through which the aerosol substrate is insertable into the heating chamber, e.g. through an open end of the heating chamber. Insulation is disposed between the heating chamber and the casing and a thermal bridge is arranged to dissipate heat from the heating chamber to the casing, for example in the vicinity of the aperture or from the open end of the heating chamber.

Abstract: An aerosol generation device has a body, a closure, and a resilient element. The body has an aperture through which an aerosol substrate is receivable. The closure is moveable relative to the aperture between a closed position in which the closure covers the aperture and an open position in which the aperture is substantially unobstructed by the closure. The resilient element is arranged so as to bias the closure towards the closed position from a first range of positions between the closed position and the open position and to bias the closure towards the open position from a second range of positions between the closed position and the open position. The first range of positions of the closure is closer to the closed position than the second range of positions. The second range of positions of the closure is closer to the open position than the first range of positions.

Abstract: An aerosol generation device has a body and a closure. The body has an aperture through which an aerosol substrate is receivable into the aerosol generation device. The closure is moveable relative to the aperture between a closed position in which the closure covers the aperture and an open position in which the aperture is substantially unobstructed by the closure; the closure is stable in each of the closed position and the open position. The closure is further moveable from the open position to an activation position. At the activation position, the aerosol generation device is operable to initiate an activation signal.

Abstract: The present invention provides a riser apparatus which is configured to rise the height of a seat, such as a toilet seat. The present invention also provides a kit comprising a riser apparatus of the invention and a seat arrangement and provides for the use of the riser apparatus and kit in order to assist a mobility impaired subject to use a seat.
