Automatic injection apparatus
First Claim
1. An automatic injection apparatus, comprisinga housing formed by a plurality of walls,one of said walls extending obliquely and constituting an injection wall,a aperture formed in said injection wall,a syringe disposed within said housing,an injection needle disposed on one end of said syringe,a support disposed within said housing upon which said syringe is tightly mounted and adapted to slide therealong, so that said needle protrudes through said aperture,means for introducing injection fluid into said syringe,a two-way, fluid-actuated, double action piston coupled to said syringe for moving the latter in both a forward and a backward direction along said support,means for fluidly connecting said piston to a source of fluid under pressure, said fluid connecting means includingmeans for introducing pressurized fluid on one side of said piston, to cause the same and said syringe to move in the forward direction, andmeans for introducing pressurized fluid on another side of said piston to cause the same and said syringe to move in the backward direction.

Abstract
The present invention relates to an automatic injection apparatus for animals, in particular for chicks, which comprises a housing, a syringe with an injection needle giving the injection through an aperture on the front wall of said housing, a two-way air double action piston being connected to said syringe and to a source of air, activating means for said piston and means for connecting the syringe to a liquid container. Said apparatus has optionally additional parts, e.g. a timer fixing the length of the period of the injection; an air regulator; means for cleaning the air; counters measuring the numbers of animals being injected and/or pre-setting the number of animals to be injected; and a disinfecting device for the needle.

1. An automatic injection apparatus, comprising
a housing formed by a plurality of walls, one of said walls extending obliquely and constituting an injection wall, a aperture formed in said injection wall, a syringe disposed within said housing, an injection needle disposed on one end of said syringe, a support disposed within said housing upon which said syringe is tightly mounted and adapted to slide therealong, so that said needle protrudes through said aperture, means for introducing injection fluid into said syringe, a two-way, fluid-actuated, double action piston coupled to said syringe for moving the latter in both a forward and a backward direction along said support, means for fluidly connecting said piston to a source of fluid under pressure, said fluid connecting means including means for introducing pressurized fluid on one side of said piston, to cause the same and said syringe to move in the forward direction, and means for introducing pressurized fluid on another side of said piston to cause the same and said syringe to move in the backward direction.

14. An automatic injection apparatus, comprising
a housing formed by a plurality of walls, one of said walls extending obliquely and constituting an injection wall, an aperture formed in said injection wall, a syringe disposed within said housing and comprising a hollow body portion, an injection needle connected to said hollow body portion, means for introducing injection fluid into said hollow body portion, a rod extending into said hollow body portion to define a space therewithin for a finite quantity of fluid to be injected, first means for adjusting position and angle of said syringe within said housing, second means for adjusting position of said rod within said hollow body portion to define the size of said space for receiving the injection fluid, means for extending said rod into said hollow body portion to contract said space and expel injection fluid through said needle, and for retracting said rod out of said hollow body portion to return said rod to the adjusted position thereof, a support disposed within said housing upon which said syringe is tightly mounted and adapted to slide therealong so that said needle protrudes through said aperture, a two-way, fluid-actuated, double action piston coupled to said syringe for moving the latter in both a forward and a backward direction along said support, said piston engaged with said extending and retracting means, means for stopping forward movement of said syringe with respect to said support, means for fluidly connecting said piston to a source of fluid under pressure, said fluid connecting means including means for introducing pressurized fluid on one side of said piston, to cause the same and said syringe to move in the forward direction, and means for introducing pressurized fluid on another side of said piston, to cause the same in said syringe to move in the backward direction.

17. An automatic injection apparatus, comprising
a housing formed by a plurality of walls, one of said walls extending obliquely and constituting an injection wall, an aperture formed in said injection wall, a syringe disposed within said housing, an injection needle disposed on one end of said syringe, a support disposed within said housing upon which said syringe is tightly mounted and adapted to slide therealong, so that said needle protrudes through said aperture, means for introducing injection fluid into said syringe, a two-way, fluid-actuated, double action piston coupled to said syringe for moving the latter in both a forward and a backward direction along said support, means for fluidly connecting said piston to a source of fluid under pressure, said fluid connecting means including means for introducing pressurized fluid on one side of said piston, to cause the same in said syringe to move in a forward direction, and means for introducing pressurized fluid on another side of said piston to cause the same and said syringe to move in the backward direction, means for disinfecting said needle comprising a container for disinfecting fluid, a sprayer disposed adjacent said needle, and conduit means for connecting said container with said sprayer, a fluid filter and lubricator disposed within said fluidly-connecting means, means for fixing said injection needle at a desired angle and at a required distance from an animal to be injected, and said syringe comprising a hollow body portion connected to said needle at one end, a rod extending into said hollow body portion to define a space therewithin for a finite quantity of fluid to be injected, means for introducing injection fluid into said space comprising an inlet and a one-way valve disposed therewithin, a one-way valve disposed between said space and said injection needle, means for adjusting position of said rod within said hollow body portion, and means for stopping forward movement of said syringe after a certain point.
