Description

Technical Field

[0001] This utility model relates to the field of drug sampling technology, and in particular to a drug quality inspection sampling device. Background Technology

[0002] Pharmaceuticals are substances used to prevent, treat, and diagnose human diseases, purposefully regulate human physiological functions, and have specified indications, functions, usage, and dosage. The quality characteristics of pharmaceuticals include efficacy, stability, and homogeneity. Efficacy refers to the ability of a pharmaceutical product to produce the expected therapeutic, preventative, and diagnostic effects on a disease under the specified indications, usage, and dosage. Stability refers to the ability of a pharmaceutical product to maintain relative quality stability under specified storage conditions; whether it is a tablet, capsule, or vial of injection, its quality should be uniform. During the pharmaceutical production process, when quality inspection is required, pharmaceutical quality inspection sampling devices are tools used to obtain representative samples from different packaging forms of pharmaceuticals. The main purpose of these devices is to ensure that the samples taken accurately reflect the quality characteristics of the entire batch of pharmaceuticals, providing reliable samples for subsequent quality inspections. However, during the sampling process, different dosages of the drug can have a significant impact on the test results, necessitating quantitative sampling.

[0003] Existing quantitative sampling structures consist of a medicine spoon, a balance, and a container. Electronic balances offer a wide range of accuracy. The medicine spoon is the most common solid sampling device, available in various shapes and materials, including flat, hemispherical, and long-handled types. For containers used for weighing and quantifying medicines, the chemical stability of the material is paramount. Glass containers are commonly used due to their excellent chemical stability and lack of chemical reaction with most medicines. The sampling device is used to slowly extract solid medicines from a pile. For powdered medicines, it can be gently scooped or removed by inserting a sampling probe into the pile and slowly rotating it. For lumpy medicines, tweezers or a medicine spoon can be used to pick them up. The extracted medicine is placed in a peeled container or directly on a weighing pan, and the weighing device reading is observed until the desired mass is reached. However, this sampling method requires manual sampling, which is time-consuming and labor-intensive. Furthermore, solid medicines still need to be crushed for testing, leading to reduced testing efficiency. Utility Model Content
