Abstract:
OBJECTIVE:To observe the changes of insoluble particles in traditional Chinese drugs injections(TCDI)mixed with infusion fluid and to study the way to solve METHODS:61 kinds of TCDI in therapeutic dosages were mixed in 0 9% sodium chloride solution,then the insoluble particles formed with diameters of 2 5?5 0?10 0 and 25 0?m were counted with Coulter counter,and determined with physical method and microscope The precise filter for liquid medicine were investigated in respect to its flow rate,quantity of flow,adsorbability and scavenging action RESULTS:(1)The number of insoluble particles in 26 kinds of TCDI exceeded the standard in ChP accounting for 42 6% of total samples observed (2)The insoluble particles included glass fragments,active carbon,rubber particles,soft flocks and residue of drugs (3)The flow rate and quantity of flow met the clinical requirement with a scavenging rate of 88 5%,and no adsorbability was found CONCLUSION:Precise infilter for liquid medicine can scavenge the particles in TCDI so as to ensure the safe use of drugs for patients
