Method and device for detecting flammable and explosive drugs by electronic micropore leak detector

Abstract

The invention discloses a method and a device for detecting flammable and explosive drugs by an electronic micropore leak detector, which belong to the technical field of drug detection equipment. Thedevice comprise an emitter and a receiver for detecting leakage of a drug bottle; a nozzle is arranged on the side edge of the emitter; the inlet of the nozzle is connected with an air pipe; the airpipe is connected with an inert gas source; and the nozzle opening of the nozzle faces the end head of the emitter. According to the electronic micropore leak detector, the fire phenomenon caused by electric arcs during detection of the electronic micropore leak detector can be eliminated, surrounding plastic structural parts are prevented from being ignited, the detection safety is improved, andthe electronic micropore leak detector can detect drugs containing flammable and combustible components.

Description

technical field [0001] The invention belongs to the technical field of drug detection equipment, and specifically relates to a method and a device for realizing the detection of flammable and explosive drugs by an electronic microporous leak detector. Background technique [0002] In the field of pharmacy, after the production of medicine bottles is completed, a leak test is required. At present, the most accurate and reliable test method is to use an electronic microporous leak detector for leak test. [0003] Such as Figure 5 As shown, the emitter of the electronic microporous leak detector generally adopts a needle-shaped structure, and it is easier to generate an arc by using the principle of tip discharge; while the receiver is generally a plate-shaped structure, which is difficult to generate an arc; in actual use, it is due to The emitter generates an arc and ignites the surrounding plastic structural parts (because the electronic microporous leak detector requires i...

Problems solved by technology

[0003] like Figure 5 As shown, the emitter of the electronic microporous leak detector generally adopts a needle-shaped structure, and it is easier to generate an arc by using the principle of tip discharge; while the receiver is generally a plate-shaped structure, which is difficult to generate an arc; in actual use, it is due to The emitter generates an arc and ignites the surrounding plastic structural parts (because the electronic microporous leak detector requires insulation around the detection electrode, plastic parts such as POM are generally used in the industry), resulting in a fire

[0004] For medicine bottles containing flammable and explosive ingredients, electronic microporous leak detectors cannot be used for airtightness testing, only traditional methods can be used for airtightness testing, such as color water method; but traditional methods have low detection accuracy, slow speed, and pollute the environment , has been eliminated, seriously affecting the quality of medicines
