Admixture technical parameters of intelligent dispensing robots for cefoperazone sodium and sulbactam sodium for injection

OBJECTIVE To explore the influence of dispensing technical parameters optimization of intelligent dispensing robots on the quality of finished infusions.METHODS Multi-factor orthogonal experiment was used to optimize the solvent volume, needle rotation speed, push-pull times, pump-pull angle, residual dilution, standing time and secondary dispensing parameters of cefoperazone sodium and sulbactam sodium for injection dispensing robots, and the number of insoluble particles in finished infusions were investigated. The pH value, osmotic pressure and number of insoluble particles were measured after stored at room temperature for 8 h. The efficiency, incidence of accidental hand injury and residual amount of liquid medicine between robot dispensing and manual dispensing were compared.RESULTS The optimal dispensing technical parameters of cefoperazone sodium and sulbactam sodium for injection were as follows: medium volume of 10 mL, low needle rotation speed, push-pull 5 times, pump-pull angle of 180°, residual dilution once, standing time of 10 s, and performing secondary dispensing. The determination of insoluble particles in finished infusions conformed to the requirement of pharmacopoeia. The properties, osmotic pressure and pH value of finished infusions did not change significantly within 8 h at room temperature. The residual amount of dispensing liquid prepared by dispensing robots was less than that by manual dispensing, and there was no accidental injury of hand. One person operating two machines at the same time was more efficient than manual dispensing.CONCLUSION The quality of finished infusions can be improved by optimizing the technical parameters of intelligent dispensing robots by orthogonal experiment.
