Description

Technical Field

[0001] The utility model relates to the technical field of drug quality detection, in particular to a drying box used for checking the difference in filling amount of sterile powder. Background Art

[0002] Drug filling volume refers to the volume of drug preparations in a unit container. Drug filling volume variance refers to the difference between the drug filling volume in a unit container and the average drug filling volume. Drug filling volume variance inspection is one of the uniformity inspection indicators of drug preparations. Drug filling volume variance inspection is applicable to sterile powder drugs for injection in rubber stopper aluminum cap glass bottles. The purpose of the inspection is to control the consistency of sterile powder drug filling volume to ensure the accuracy of the dosage. Drug filling volume variance inspection plays an important role in ensuring the safety of public drug use and protecting public health.

[0003] Sterile powder for injection should be checked for filling difference. During the inspection, five bottles of samples are taken and a balance is used to check the filling difference between the five bottles of samples by removing the weight difference before and after the sample. During the inspection, the molded bottles containing sterile powder for injection need to be dried and then weighed. Currently, drying and weighing are mostly manual operations. The molded bottles will inevitably come into direct contact with the operators and objects in the surrounding environment to cause collision and friction, which will have an adverse effect on the accuracy of the sample filling difference inspection. This adverse effect is particularly evident on samples with smaller filling amounts. In addition, when multiple batches are inspected, the number of samples is large, and it is impossible to affix labels to the molded bottles containing samples when performing filling difference inspections. The identification and marking of samples greatly increases the workload of inspectors. Utility Model Content
