Abstract
An injector to deliver a variable dose into a living creature, such as an animal, the injector having a mounting element with an elongated, straight handle to be gripped by the user, a cylinder fixed to the mounting element, a piston movably associated within the cylinder to define a variable volume working space, a tube connected to the piston and fluidly connected to the space through the piston, a needle fluidly communicating with the space, check valves controlling the flow of fluid, a pad associated with the needle and the mounting element, the pad having a face with an oblique angle of engagement with the animal, the piston movable to a cocked position by the tube where it is retained until automatically released upon said pad contacting the animal and being moved toward the body, and thereby permitting the needle to be inserted into the animal, the pad engaging a latch binding the tube in the cocked position for releasing the tube and piston for passage of fluid from the space through the needle, a pawl for holding the latch in a non-tube binding position until a full dose of fluid has been ejected through the needle and further ensuring full needle penetration, and an element connected to the tube for engagement with the handle for varying the amount of the working space.
