Embodiment Construction

[0023] The present invention is a method for automatic detection of sterile liquid injections. The realization of the method is based on an aseptic detection system, and the aseptic detection system includes three work areas: a 10,000-level preparation area (10,000-level cleanliness level), an isolation and sterilization area , 100-class ultra-clean work area (100-class cleanliness level), and several conveying mechanisms that can carry out conveying operations in the three work areas. The method includes the following steps in turn:

[0024] S1. Preparatory work: Install the items required for the aseptic test operation on multiple conveying mechanisms in the 10,000-level preparation area in sequence. The items required for the aseptic test operation include bacteria collectors, sample ampoules, rinse solution bottles and Culture bottle;

[0025] S2. Sterilize in the isolation sterilization area: Three conveying mechanisms transport multiple bacteria collectors, sample ampoul...

Abstract

The invention provides a method for automatically detecting sterile liquid injections. The method specifically comprises the following steps: sequentially mounting articles required by sterile test operation on a plurality of conveying mechanisms in a ten-thousand-level preparation area; conveying a bacterium collector, a sample ampoule, a flushing liquid bottle and a culture liquid bottle to an isolation sterilization area and a hundred-grade ultra-clean working area through a conveying mechanism, and after surface sterilization is conducted, installing a liquid suction needle of the bacterium collector on a liquid suction mechanism; breaking a sample ampoule and absorbing liquid in a hundred-grade ultra-clean working area, and injecting the sample ampoule into a bacterium collector; then filtering the sample preparation in the bacterium collector; then flushing the bacterium collector and injecting culture solution into the collector, and finally, respectively returning and conveying the bacterium collector, the sample ampoule, the flushing liquid bottle and the culture liquid bottle to a ten-thousand-level preparation area, and taking down the bacterium collector, the sample ampoule, the flushing liquid bottle and the culture liquid bottle by an operator. According to the method, external pollution can be isolated, and sterility test work is guaranteed.

Description

【Technical field】 [0001] The invention relates to the technical field of pharmaceutical production inspection methods, in particular to an automatic inspection method for sterile liquid injections. 【Background technique】 [0002] Microbial contamination is one of the main causes of adverse drug events. Preventing contaminated drugs from entering the market is of great significance for ensuring the safety of patients. Strict control of microorganisms will be required in clinical medicine, so there is a practical demand for strict control and inspection of microorganisms in the production process and quality inspection process. The detection operation in the prior art is performed manually on an ultra-clean workbench, which is relatively open, and it is difficult to avoid contamination of the items to be inspected during the operation process, which affects the detection results. A method for automatic detection of sterile liquid injections is now proposed. 【Content of inven...
