Electromechanical injection apparatus for medical and veterinary use actuated by a trigger
First Claim
1. In an electromechanical injection device for medical and veterinary use comprising a frame (1) having the shape of a pistol provided with a stock and along a longitudinal axis of said frame (2) and bearing a movable carriage (3) that supports a removable syringe (4) having a needle (5) and a piston (6), a first motor (7) actuating a pusher (8) which acts against the piston (6) of the syringe (4), a cradle (9) carried by the frame (1) and supporting the syringe (4) on the movable carriage (3), a second motor (12) actuating the movable carriage (3), the forward portion of the frame having a stabilizing sight (10) for application to the skin which guides and predetermines the degree of penetration of the needle (5), an adjustment wheel (11) which permits adjusting the position of the sight (10) to adjust the depth of penetration of the needle (5), and a trigger (18) to actuate said motors (7, 12);
- the improvement wherein said second motor (12) is fixed to the frame (1) and has a rotatable axle (30), a first cam (29) on said axle, said second motor (12) driving, via said axle (30) and said first cam (29) said movable carriage (3) in movement along said longitudinal axis of said frame (1), a second cam (26) on said trigger (18), said first and second cams (29,
26) coacting with each other according to the translated position of the trigger (18) to control advancement of said piston (6).

Abstract
An electromechanical injection device for medical and veterinary use comprises a frame (1) having the shape of a pistol provided with a stock (2) and bearing a movable carriage (3) that supports a removable syringe (4) having a needle (5) and a piston (6). A first motor (7) actuates a pusher (8) which acts against the piston (6) of the syringe (4). A cradle (9) is carried by the frame (1) and supports the syringe (4) on the movable carriage (3). A second motor (12) actuates the movable carriage (3). The forward portion of the frame has a stabilizing sight (10) for application to the skin which guides and predetermines the degree of penetration of the needle (5). An adjustment wheel (11) permits adjusting the position of the sight (10) to adjust the depth of penetration of the needle (5). A trigger (18) actuates the motors (7, 12). The second motor (12 ) is fixed to the frame (1) and has a rotatable axle (30) and a first cam (29) on that axle. The second motor (12) drives, via that axle (30) and the first cam (29), the movable carriage (3) in movement lengthwise of the frame (1). There is a second cam (26) on the trigger (18). The first and second cams (29, 26) coact with each other according to the translated position of the trigger (18) to control advancement of the piston (6).
