A medicament injection device including a needle, a first stage that controls positioning of the needle at a depth into an animal when the device is pressed against the animal, and a second stage that injects the medicament through the needle into the animal after the needle is positioned at the depth and the device is further pressed against the animal. The device preferably includes a mechanism that permits the second stage to inject the medicament only after the needle is positioned at the depth. The depth of the needle preferably is adjustable, as is the amount of the medicament injected. In preferred aspects, these two features are independently adjustable. One or more springs, pneumatics elements, or other elements may automatically reset the first stage, the second stage, or both after the device is withdrawn from the animal. Also, associated methods.

An injector including at least one fluid reservoir having a needle, a surface attached to skin and coupled to the fluid reservoir by at least a first joint and a second joint at least a portion of one of the joints being slidable or having interlocking arms. At least a portion of a path of translation of a slidable portion of the first joint and a portion of a path of translation of the second joint are angled in respect to each another.

A delivery tool connectable with a syringe can be used to deliver a viscoelastic solution. The tool includes a first segment, a second segment and an inner lumen defined by the first and second segments. A distal portion extends from the second segment in a curved manner.

An injection apparatus for injecting a medicament into a patient, the injection apparatus has a stationary head and a movable head that is movable with respect to the stationary head. A needle is attached to a needle holder that is held by the movable head and by the stationary head. When the movable head is urged rearwardly, a front edge of the needle moves forwardly with respect to a front face of the movable head.

The invention relates to a cartridge for storing, discharging and applying a dental compound, in particular a paste for preparing and drying the gingival sulcus (sulcus gingivae) during dental impression taking. The invention relates to a cartridge (1) for storing, discharging and applying a dental compound, comprising a container (2), which has a hollow chamber (4) for accommodating the dental compound, and a cannula (3). The hollow chamber (4) comprises an outlet opening (5) and an actuator opening (6) opposite the outlet opening (5), and the cannula (3) is fluid-connected to the outlet opening (5), is arranged on the container (2) and is straight in the starting state. The cartridge is characterised in that the cannula (3) is made of plastic and is plastically deformable under standard conditions with the application of manual force in such a manner that a permanent bend by an angle of at least up to 65 in comparison with the starting state can be achieved without buckling the cannula (3).

A pharmaceutical delivery device includes a cartridge containing a fluid. The cartridge includes a light pipe section having an input location and a light diffusing section optically coupled to the light pipe. A light source is optically coupled to the cartridge at the input location to the light pipe, such that at least some light from the light source entering at the input location is diffused at the light diffusing section.
