Claim 1:
2. A process for intelligent injection of a substance using the device according to claim 1, wherein, for a condition where an embryo is touched and where the substance to be inoculated is a nutrient or nutritional vaccine complex, the operational kinematics of the device are defined by the following steps:
descending the support platform until the coupling cup touches the upper surface of the fertile egg, and locking the device in the vertical position;
moving the perforator in linear motion towards a shell;
advancing the injection needle, wherein the stepper motor is activated to provide rotational movement of the spindle axis for downward displacement of the needle support platform and the injection needle, where a Programmable Logic Controller (PLC) calculates the displacement having a reference line and the number of electrical pulses sent by the stepper motor;
interrupting injection needle displacement at the moment when the injection needle touches the embryo, wherein the mass of the embryo shows resistance to perforation, causing an opposite force next to the injection needle that displaces the support platform of the injection needle and the needle coupler upwardly, with also displacement upward from the stepper motor and the platform, wherein when platform stops having contact with the touch sensor, a signal is sent to the PLC that recognises the embryo encounter;
retreating the injection needle when the PLC sends a signal for inversion of the rotation of the stepper motor, and consequent inversion of the rotation of the spindle axis, thereby promoting a discrete displacement of the needle support platform and needle coupler and the consequent slight retreat of the injection needle, wherein the injection needle becomes free in amniotic fluid;
inoculating the embryo when the injection needle is free in the amniotic fluid, the PLC emits a signal to a substance injection mechanism;
retracting the injection needle when the PLC sends a signal for inversion of rotation of the stepper motor, with an inversion of rotation of the spindle axis to retreat displacement of the needle support platform and the needle coupler; and
raising the support platform when the PLC sends a signal to the support platform to provide an upward movement of the support platform, thereby returning the entire device to its original position, and away from the fertile egg inoculated with the nutrient or nutritional vaccine complex.
