    Abstract: A micro-needle device (100, 200, 300) for delivering a dental local anesthetic that includes a micro-needle array (102, 202, 302) and a hollow spheroid shaped container (108, 208, 308). The micro-needle array has a base (104, 204, 304)and two or more of an elongate micro-needle (106, 206, 306). The elongate micro-needle has an interior surface (110, 210, 310) defining an opening (112, 212, 312) through the elongate micro-needle and the base has a first major surface (114, 214, 314) and a second major surface (116, 216, 316) through which the opening of the elongate micro-needle passes to provide a passage across the base. The hollow spheroid shaped container includes an inside surface (120, 220, 320), where the first major surface of the base and the inside surface of the hollow spheroid shaped container define a volume that is in fluid connection with each opening of the two or more of the elongate micro-needle. This allows the dental local anesthetic to flow from the volume of the micro-needle device through the opening of the two or more of the elongate micro-needle.

    Abstract: A device for mixing and dispensing at least two flowable components comprises a housing front face with an outlet for the components and a piston having a piston front face. The piston is arranged such that the piston front face and the housing front face are facing each other. The piston front face and the housing front face are adapted to form a channel for the components between each other. The device is adapted to reduce the channel upon urging the piston front face and the housing front face against each other and thereby to displace the components to flow toward the outlet. The device facilitates mixing and dispensing a multi-component dental material.

    Abstract translation: 用于混合和分配至少两个可流动部件的装置包括具有用于部件的出口的壳体正面和具有活塞正面的活塞。 活塞被布置成使得活塞正面和壳体前表面彼此面对。 活塞前表面和壳体前表面适于形成用于彼此之间的部件的通道。 该装置适于在将活塞前表面和壳体前表面相互抵靠的同时减小通道，从而使部件移动以朝向出口流动。 该装置促进混合和分配多组分牙科材料。

    Abstract: A dispensing gun for dispensing a dental material. The dispensing gun has a body with a receptacle for receiving a cartridge therein, a plunger that is displaceable relative to the receptacle, and a lever that is suspended pivotally relative to the body. The plunger has a linear toothing and the lever has an annular gear segment. The linear toothing and the annular gear segment are permanently engaged with each other so that any pivot of the lever in a first direction causes the plunger to displace forward and any pivot of the lever in an opposite second direction causes the plunger to displace backward.
