Liquid drug comprises injection, infusion solutions, oral liquid, eye drops etc., usually adopt vial or plastic bottle to carry out can,, cleaning container not good owing to filtering in the production run not thoroughly, the reason such as collide in encapsulation or the transportation, can make container at the visible foreign matters of chips of glass, suspension such as cilium, hair, insoluble particle etc. and other types.On the stricti jurise, " visible foreign matters " refers to the visual insoluble substance that can observe under rated condition, generally is present in injection, eye drops or other liquid preparations, and its particle diameter or length are usually greater than 50 μ m.
China's pharmacopeia was namely stipulated to carry out clarity to the detection of liquid preparation medicine and is detected and the particulate matter inspection from 1985, the foreign matter in the medicine and particulate are strictly controlled.On August 24th, 1999, national Bureau of Drugs Supervision is about enforcement＜GMP〉in the notice of relevant regulations, explicitly call for pharmaceutical producing enterprise must before the end of the year 2000, pass through GMP (good) authentication." Chinese Pharmacopoeia 2005 version execution in 1 day July in 2005, former " clarity test detailed rules and regulations and criterion " revision is " visible foreign matters inspection technique ", the further clear and definite medicines such as injection, eye drops must be produced under the condition that meets GMP (GMP), should adopt suitable method to check one by one before the product export and reject simultaneously substandard product.
At present, for the visible foreign matters inspection method in liquid preparation such as injection, the ampoule bottle lamp test and light scattering method are arranged usually.
In lamp test, how detection is provided is very important with light.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of light supply apparatus for the visible foreign matters detection system is provided, this light supply apparatus can provide the polarized light that is applicable to detect visible foreign matters, when under polarized light, the visible foreign matters in injection, eye drops or other liquid preparations etc. being detected, accuracy of detection can be improved, and the visual fatigue of testing staff when detecting can be eliminated.
One of the purpose of this utility model is to provide a kind of light supply apparatus for the visible foreign matters detection system, it is characterized in that, described light-emitting device comprises light-source box, wherein is disposed with light source body, scattering sheet and the polarizer from light-source box rear portion to front portion.
Two of the purpose of this utility model is to provide above-mentioned light supply apparatus for the visible foreign matters detection system, it is characterized in that, light source body is arranged in the light-source box near the place, rear portion.
Three of the purpose of this utility model is to provide above-mentioned light supply apparatus for the visible foreign matters detection system, it is characterized in that, light source body is comprised of luminophor and holder, and luminophor is arranged on the holder.
Four of the purpose of this utility model is to provide above-mentioned light supply apparatus for the visible foreign matters detection system, it is characterized in that, described luminophor is incandescent lamp, cold-cathode lamp or LED lamp.
Five of the purpose of this utility model is to provide above-mentioned light supply apparatus for the visible foreign matters detection system, it is characterized in that, scattering sheet and the polarizer are arranged at the front portion of light-source box.
Six of the purpose of this utility model is to provide above-mentioned light supply apparatus for the visible foreign matters detection system, it is characterized in that the central axes of light source body, scattering sheet and the polarizer.
Seven of the purpose of this utility model is to provide above-mentioned light supply apparatus for the visible foreign matters detection system, it is characterized in that, the described polarizer is polaroid.
Eight of the purpose of this utility model is to provide above-mentioned light supply apparatus for the visible foreign matters detection system, it is characterized in that, the groove of above-below direction or track is set as guided way in the exterior side surface of light-source box.
Use light with light supply apparatus for generation of the visible foreign matters detection according to visible foreign matters detection system of the present utility model, for the visible foreign matters detection system.The light that is sent by light source body forms uniform optical plane after scattering sheet, again through forming uniform polarized light behind the polarizer.In the utility model, the detection light that light supply apparatus produces is polarized light.Test sample under polarized light can make the observation visual field more clear, and eliminate visual fatigue.This light supply apparatus, simple for structure being easy to made, and production cost is low.
