Detection system of visible foreign matters

Abstract

The invention discloses a detection system of visible foreign matters. The detection system comprises a light source device, a detection observation device and a swing arm clamping device. The detection system adopts the lamp detection method principle, checks samples in polarized light and removes fatigue of human eyes. A swing arm mechanism simulating human hand actions is adopted so that action consistency is kept and guarantee is provided for result reproducibility. An observation window can be used for an operator to directly view the detection process, and a liquid crystal screen on the side of the observation window synchronously displays the process. An image collector is used for snap-shooting instant characteristics of the visible foreign matters, distinguishing image information in pictures and verifying accuracy of detection reports in picture mode. Therefore, influence of human factors on detection results is fundamentally removed.

Description

technical field [0001] The invention relates to a system for detecting visible foreign matter, the system is mainly used for detecting visible foreign matter in various injections and ampoules, or for online detection of the production process, belonging to injections, eye drops or other liquid preparations, etc. Solution sample testing and online testing in the production process. Background technique [0002] Liquid medicines include injections, infusions, oral solutions, eye drops, etc., and are usually filled in glass or plastic bottles. Due to poor filtration during production, incomplete cleaning of containers, collisions during packaging or transportation, etc., There will be glass shavings, suspended matter such as cilia, hair, insoluble particles, etc., and other types of visible foreign matter in the container. Strictly speaking, "visible foreign matter" refers to an insoluble substance that can be observed visually under specified conditions, and generally exists...

AI Technical Summary

Problems solved by technology

[0007] 1) Under strong light, it is very easy to cause eye fatigue and affect the test results;

[0008] 2) Factors such as the experience and eyesight of the operator have a great influence on the test results;

[0009] 3) It can be seen that the foreign matter characterization is relatively random in the detection and the reproducibility is poor, which affects the persuasiveness of the detection results

The disadvantages are: 1) limited by the sample fixture, the range of samples that can be inspected is very narrow; 2) the quality of the solution bottle has a certain impact on the inspection results; 3) the detection effect on the bottom of the bottle is poor; 4) the method determines Unqualified samples must be confirmed by light inspection; 5) The production cost of the instrument is relatively high; it is not conducive to the popularization of the application field
