A device for dispensing a fluid drop-by-drop can include a fluid connector to supply the fluid to be dispensed, a pump which is fluidically connected to the fluid connector, an outlet nozzle which is fluidically connected to the pump, an actuating element, and a control unit. When the actuating element is actuated, the control unit activates the pump which pumps the supplied fluid to the outlet nozzle for dispensing drop-by-drop. The outlet nozzle has an outlet opening and a fluid channel which extends as far as the outlet opening and which, in the direction of the fluid from the pump as far as the outlet opening, has a first channel portion with a first cross-sectional surface and a second channel portion with a second cross-sectional surface adjoining the first channel portion. The second cross-sectional surface can be smaller than the first cross-sectional surface.

In one aspect there is provided a self-removing animal injection apparatus for injecting an animal with a liquid medication. The apparatus comprises a shaft having a first end and a syringe. A needle is provided at the first end of the shaft and defines a longitudinal direction. The needle is in fluid communication with the syringe. First and second disengaging members are movable substantially along the longitudinal direction and operable to assist with disengagement of the animal injection apparatus from the animal, once at least some of the liquid medication has been injected into the animal.

An arrangement for delivery of a substance to an animal and a method of protection of a winged capsule. The arrangement may include a winged capsule including a capsule and wings, the capsule being adapted to deliver the substance to the animal, and the wings affixed to the capsule and operable to fold for insertion into the animal and to expand after insertion. The arrangement may include a wing protector including a slot sized and configured to receive at least a portion of each of the wings and removably attach the winged capsule to the wing protector. The method may include removably attaching the winged capsule to the wing protector to form a protected winged capsule; inserting a plurality of the protected winged capsule into a bag; removing one of the protected winged capsule from the bag; and removing the wing protector from the protected winged capsule.

A dispenser includes an outer shell and diaphragm pumps that can be operated by an animal to dispense materials, such as a gel, with a flow viscosity between 1-100,000 cps. The outer shell houses a pressure-actuated sound generator and has outer surfaces with tongue cleaners. The outer shell includes receivers wherein diaphragm pumps can be installed. The diaphragm pumps are of a prescribed volume between 0.1 ml and 50 ml so that the amount of oral gel ejected into a dog's mouth can be determined. The outer shell is sufficiently flexible to be compressed by an animal's jaws such that the oral gel is pumped via actuation of the diaphragm pump. Gel is ejected or pumped to the teeth of the animal and in combination of sounds being generated, more or less simultaneously with the distribution of oral gel in a prescribed and measured volume.

Device for dispensing a pulverulent product comprising a reservoir unit (100) connected on the one hand, to an air expulsion system (200) and on the other hand to a dispensing head (300) provided with a dispensing orifice (310), said reservoir unit (100) comprising a reservoir (110) having substantially the form of a hollow cylinder, with a distal opening (111), a proximal opening (112), and a metering passage (113) connecting said distal and proximal openings (111, 112), a one-way valve (115) being positioned between said metering passage (113) and said distal opening (111), said proximal opening (112) of said reservoir (110) forming a filling cone which tapers towards said metering passage (113) to facilitate filling of said metering passage (113) with a dose of powder.

A device for administering a fluid can include a cylinder, a piston connected to a piston rod, and a tensioning device connected to the piston rod. The tensioning device includes a ramp which is rotatable via a motor, a ramp track, and a roller which is in contact with the ramp track and which is mounted rotatably in a driver. The driver can be connected to the piston rod via a joint. In a tensioning procedure, the ramp track is rotated such that the roller runs on the region of inclination as far as the second plateau and the piston is thereby moved to its rear end position. In a dispensing procedure, the ramp track is rotated until the roller runs over a transfer region and, on account of the tensioning, is accelerated toward the first plateau and, as a result, the piston is moved toward the an dispensing end.

A winged capsule (10) including a capsule (14) having a bottom wall (143) and tubular wall (141) extending from the bottom wall, the tubular wall and the bottom wall defining an inner space adapted to contain a substance (17), and the bottom wall having an aperture (144) adapted to deliver the substance to the animal; and a capsule retainer (18) including a central wing portion (180) connected to the capsule and wings (182) connected to and extending laterally from the central wing portion along a wing plane, the central wing portion having a maximum central width (W.sub.t), wherein each of the wings has a distal end having a distal width and an Intermediate portion between the distal end and the central wing portion, the intermediate portion having a width narrowing from a width adjacent the central wing portion to the distal width.
