Detection method and detection system for foreign matters in infusion bottle

Abstract

The invention relates to a detection method and a detection system for foreign matters in an infusion bottle. The detection method comprises the following steps of: rotating a to-be-detected infusion bottle; photographing the bottle by utilizing a camera so as to obtain a multi-frame image; processing the image to obtain feature information of blocks in the bottle; removing the blocks formed by interferences of bubbles and lights; and comparing the feature information of the residual blocks with a detection standard, and judging whether the foreign matters exist, so as to judge whether the infusion bottle is qualified. The detection system comprises an intermittent rotating device and the camera, wherein upper compression devices and lower compression devices for fixing the relative positions of the to-be-detected infusion bottle and the intermittent rotating device are arranged on the intermittent rotating device, and friction wheels for driving the upper compression devices and the lower compression devices to rotate are arranged at the outer side of the intermittent rotating device. By utilizing the detection method and the detection system, the automatic detection on the foreign matters in the infusion bottle can be realized, and the problems of low efficiency, high labor intensity, easiness in generation of quality fluctuation and the like in the conventional detection method are solved; a reliable detection result can be obtained, and the export quality of products is effectively guaranteed.

Description

technical field [0001] The invention relates to a detection method and a detection system for foreign matter in an infusion bottle, which belongs to the technical field of detection and is mainly used for on-line detection of automatic production lines such as food and medicine. Background technique [0002] Medical infusion bottles have very high requirements on the cleanliness of the liquid in the bottle, but due to the production process or production environment, the finished infusion may be mixed with tiny foreign objects such as glass chips, aluminum chips, rubber chips, hair, fibers or insoluble drugs . The particles of these foreign bodies are small, and may enter the human body along with the infusion during intravenous infusion, causing blood vessel blockage, resulting in cystic phenomenon, and seriously endangering the life and health of patients. [0003] According to the provisions of the Chinese Pharmacopoeia, in the production process of infusion bottles, the...

AI Technical Summary

Problems solved by technology

The particle size of these foreign bodies is small. During the intravenous infusion, they may enter the human body with the infusion, resulting in blood vessel blockage and cystic phenomenon, seriously endangering the life and health of the patient.

[0003] According to the provisions of the Chinese Pharmacopoeia, in the production process of infusion bottles, the insoluble substances in the injections in the infusion bottles should be inspected one by one, while the traditional inspection method is to inspect directly through artificial vision. , use human eyes to directly observe the bottled liquid medicine, find out whether there are foreign objects and judge the size of the foreign objects. Visual fatigue and quality fluctuations are prominent problems in automated production lines
