摘要： An auto-injector assembly comprises a medicament container defining a substantially cylindrical chamber containing a liquid medicament. A proximal end of the chamber is closed by a piston and a distal end of the chamber is closed by a seal spanning an opening. A biasing means, such as a spring, is coupled to the piston and acts to bias the piston towards the seal, thereby pressurizing the liquid medicament. The assembly also comprises a hypodermic needle and a removable needle cap for maintaining the hypodermic needle in sterile conditions until use. A means for establishes fluid communication between the chamber and the hypodermic needle such that the pressurized liquid medicament is automatically delivered through the hypodermic needle when communication has been established.

摘要： A device (200) for mixing first and second substances. The device comprises a first container (100) for storage of the first substance and a second container (150) received in the first container (100) and for storage of the second substance. An outlet (112) is disposed at the distal end of the first container (100). Valve means (180) are provided for closing a distal end of the second container (150) and a proximal end of the first container (100). A stopper means (166) closes a proximal end of the second chamber (152) and is movable with respect to the second container (150). An operating mechanism drives relative movement between the first and second containers for causing displacement of the second substance into the first chamber (102) through the valve means (180) when the outlet (112) is closed, for mixing the first and second substances in a mixing stroke of the device.

摘要： A blister strip which can be stuck onto the skin, is formed from at least two sheets and has an applicator for applying a medium contained in the blister to the skin, wherein the blister strip includes an upper sheet, with at least one protuberance, wherein the underside of the upper sheet, the underside enclosing the protuberance, is of adhesive configuration. The blister strip has a lower sheet, which covers the lower surface of the blister strip and can be drawn off from the adhesive underside of the upper sheet. The protuberance contains an applicator, separating the protuberance into at least two sub-volumes. Wherein the applicator has at least one opening, which connects two sub-volumes, wherein one sub-volume is located between the applicator and the lower sheet, and wherein at least one sub-volume is entirely surrounded by the inner surface of the protuberance and the applicator, and contains the medium.

摘要： An injection device suitable for use with infants is disclosed. The injection device is formed from a body shield member and a cylindrical handle. The body shield member includes a concave flange at the base, which is pressed against the patient's limb and reduces local compression at the needle insertion site. The injection device also has a softer form and operates through a pressing motion. A catch member is located in the cylindrical handle, and is deployed upon fully depressing the handle. Once the handle returns to its starting position, the catch member prevents the handle from being depressed a second time and permitting the used needle to be exposed.

摘要： Add-on module (100) for logging the value of an expelled dose from a pen-type drug injector (200), comprising a magnetic sensor system comprising first and second sensor means (745/746) as well as a mechanical dose setting and expelling mechanism comprising a magnetic clutch element (240/740) which rotates during drug expelling. The system further comprises processor means configured to determine (i) on the basis of measured values from the first sensor means, a rotational position of the clutch element, (ii) on the basis of measured values from the second sensor means, a high-speed condition in which the rotational speed of the clutch element exceeds a given threshold level, and (iii) indicate an error state if the high-speed condition is detected.

摘要： A fluid delivery device comprises a drive unit including an actuator and one or more first features and a cartridge filled with a fluid prior to being inserted into the housing. The cartridge having a fluid reservoir sealed at one end by a movable piston and sealed at another end by a pierceable septum. The cartridge includes one or more second features that are configured to align and mate with the one or more first features allowing the cartridge to be inserted into the drive unit. The piston is moveabe by the actuator once the cartridge is inserted into the drive unit.

摘要： The present disclosure relates to a medicament delivery device comprising a housing, a reservoir for medicament disposed in the housing and a dispensing member. The dispensing member is moveable relative to the housing from a first position to a second position to dispense medicament from the reservoir when the reservoir contains medicament. The medicament delivery device further comprises first and second biasing members. The first biasing member is configured to urge the dispensing member from the first position to an intermediate position. The second biasing member is configured to urge the dispensing member from the intermediate position to the second position.

摘要： A wearable drug delivery device that can deliver a liquid drug stored in a container to a patient is provided. The container can be a prefilled cartridge that can be loaded into the drug delivery device by the patient or that can be preloaded within the drug delivery device when provided to the patient. A sealed end of the container is pierced to couple the stored liquid drug to a needle conduit that is coupled to a needle insertion component that provides access to the patient. A drive system of the drug delivery device can expel the liquid drug from the cartridge to the patient through the needle conduit. The drive system can be controlled to provide the liquid drug to the patient in a single dose or over multiple doses.

摘要： An autoinjector having a body (1; 2), a reservoir (S), a piston (P), a needle (A), and a piston rod (5) co-operating with the piston. The piston rod is movable between a first rest position, a second pricking position, and a third injection position. An actuator spring (6) is provided to urge the piston rod towards its pricking position and then towards its injection position. A force-adjustment system (7, 8) exerts a force (F1, F2) on the piston rod (5). The force (F1) opposes the force exerted by the actuator spring at the end of pricking to decrease the force exerted on the reservoir by the piston rod at the end of pricking, and the force (F2) adding to the force exerted by the actuator spring at the beginning of injection, to amplify the force exerted on the piston by the piston rod at the beginning of injection.

摘要： A device for injecting a medicament includes a housing for a medicament container assembly, and an activation member axially movable relative to the housing between extended and retracted positions with a gripping member. A movement guide mechanism includes a first guide, a second guide that has a locking portion, and a guide follower that slides along the first guide when the activation member moves from the extended position to the retracted position and that slides along the second guide when the activation member moves from the retracted position to the extended position. The gripping member engages the container assembly when the activation member is in the retracted position. The locking portion interacts with the guide follower when the activation member moves from the retracted position to the extended position to restrict movement of the activation member. A method of assembling a delivery device is also disclosed.
