Estimating the term…
The automatic injection device of the invention comprises an injection syringe having a syringe body provided with a lateral injection-liquid supply tubulure, retention means for retaining the animal to be treated, enabling the latter to be placed in a given transverse position and at a given angle with respect to the syringe, syringe displacement means for advancing and withdrawing the syringe at each injection, and piston displacement means for displacing the piston with respect to the syringe body. Such a device enables for example about at least 2000 chicks to be vaccinated per hour, while at the same time ensuring a dosing accuracy on the order of 1/100 and an exact location of the point of injection.
Automatic injection device comprising a casing formed by a plurality of peripheral walls, syringe support means rigidly mounted in said casing, an injection syringe located within said casing and including a syringe body slidably mounted on said syringe support means and provided with a lateral injection-liquid supply tubulure, a syringe piston provided with a piston rod and adapted to slide in said syringe body, and an injection needle rigidly secured to said syringe body, retention means for immobilizing a part of an animal to be treated, said retention means comprising at least one retention plate formed by one of said peripheral walls and having an external surface which is a part of the outer surface of the casing, and at least one stop member rigidly secured to said retention plate and extending outside of said casing, parallel to and in contact with a part of the external surface of said retention plate, said stop member having a plane elongated main abuutment face and at least one auxiliary abutment face, each face being substantially perpendicular to said retention plate and being angularly related one to the other, first displacement means for advancing and withdrawing the syringe body, at each injection, with respect to said retention means, and piston displacement means for displacing said piston with respect to said syringe body, said retention plate being provided with an aperture which opens at a point located close to said main abutment face and in the vicinity of said auxiliary abutment face, on a part of the external surface of said retention plate which is clear of said stop member, through which aperture said injection needle may be displaced with respect to said retention plate by said first displacement means so as to protrude outwardly beyond the external surface of the retention plate in the advanced position of the syringe body thereby enabling injection, said injection needle being inwardly disposed relative to said external surface in the withdrawn position of the syringe body.
