The intracardiac medicine feeding device according to claim 6, wherein the medicine feeding control unit is provided with a first medicine liquid residue mass percentage standard B1, a second medicine liquid residue mass percentage standard B2, and a dispersion adjustment coefficient α, wherein B1% < B1 < B2 < 10%, and α < 1, and when the medicine liquid preparation unit completes the preparation of the primarily dispersed medicine liquid, the medicine feeding control unit controls the medicine liquid preparation unit to deliver the primarily dispersed medicine liquid into the liquid storage box, the medicine feeding control unit controls the monitoring unit to sequentially detect a total weight mb1 of the primarily dispersed liquid in the mixing bottle and a weight mb2 of the remaining medicine liquid residue in the mixing bottle after the medicine liquid is delivered to the liquid storage box, and calculates a medicine liquid residue mass percentage B from mb1 and mb2, the medicine feeding control unit compares B with B1, B2 to determine a liquid amount of the pre-prepared medicine solution to be introduced, and sets B = mb2/mb1,
when B is less than B1, the medicine feeding control unit judges that the medicine liquid residues meet the standard and controls the medicine liquid preparation unit to introduce a prepared pure water dispersion liquid with the volume of Lb into the mixing bottle to disperse the medicine liquid residues to form a secondary dispersed medicine liquid, and Lb = Lb0 is set, and Lb0 is the volume of a preset dissolved medicine residue dispersion medium;
when B is more than or equal to B1 and less than B2, the medicine feeding control unit judges that the medicine liquid residue does not meet the standard and the medicine liquid residue amount is low, the medicine feeding control unit controls the medicine liquid preparation unit to introduce a prefabricated first viscosity dispersion liquid with the volume of Lb into the mixing bottle to disperse the medicine liquid residue to form a secondary dispersed medicine liquid, and Lb = Lb0 is set;
when B is larger than or equal to B, the medicine feeding control unit judges that the medicine liquid residue does not meet the standard and the medicine liquid residue is high, the medicine feeding control unit controls the medicine liquid preparation unit to introduce a prefabricated second viscosity dispersion liquid with the volume of Lb into the mixing bottle to disperse the medicine liquid residue to form a secondary dispersed medicine liquid, and Lb = alpha x mb 2/(1-B) -mb2 is set.
8. The intracardiac drug feeding device according to claim 7, wherein the drug feeding control unit is provided with a drug solution alert volume height H1, wherein H1 > 0, and when the drug solution delivery unit delivers the mixed drug solution to the patient's mouth, the drug feeding control unit controls the monitoring unit to detect the level H of the drug solution in the patient's mouth and to determine whether to continue to deliver the mixed drug solution to the patient's mouth according to H,
when H is less than H1, the medicine feeding control unit judges that the amount of the liquid medicine in the oral cavity is small and controls the liquid medicine conveying unit to convey the mixed liquid medicine to the oral cavity of the patient;
when H is larger than or equal to H1, the medicine feeding control unit judges that the amount of the liquid medicine in the oral cavity is large, controls the liquid medicine conveying unit to stop working, and determines whether to adjust the medicine feeding mode of the patient according to the liquid level H of the liquid medicine in the oral cavity of the patient.
9. The intracardiac medicine feeding device of claim 8, wherein the medicine feeding control unit is provided with a swallowing marker liquid level H2, wherein H2 is more than 0 and less than 0.6H1, when the medicine feeding control unit determines that the amount of the liquid medicine in the oral cavity is large, the medicine feeding control unit determines whether the patient has swallowing abnormality according to the liquid level H of the liquid medicine in the oral cavity of the patient after a preset time ty and determines whether the anti-choking negative pressure backflow unit is started to work to lead out the liquid in the oral cavity of the patient,
when H is less than H2, the medicine feeding control unit judges that the liquid level in the oral cavity meets the swallowing standard and the patient does not have the choking cough, and controls the anti-choking negative pressure backflow unit to be closed and controls the liquid medicine conveying unit to convey the mixed liquid medicine to the oral cavity of the patient;
when H is larger than or equal to H2, the medicine feeding control unit judges that the liquid level in the oral cavity does not meet the swallowing standard and the patient has chocking cough, and the medicine feeding control unit controls the anti-chocking negative pressure backflow unit to be started so as to suck the liquid in the oral cavity of the patient to the recovery box.
