Problems solved by technology
There is no automatic preprocessing equipment with high degree of automation, rich functions and general purpose at home and abroad.
The manual pretreatment of medicines has various disadvantages: for example, the container is open or poorly sealed, and the volatilization of organic reagents endangers the health of the inspectors; the volume of the solution after adding pretreatment reagents and extraction treatment is not accurate enough; the pretreatment steps are cumbersome and cumbersome. The inspectors are prone to misoperation; the number of inspection batches is large, the inspection task is urgent, the inspection workload is heavy, the efficiency of manual pretreatment is low, and the repeatability is poor, which cannot meet the requirements of mass inspection; pretreatment requires a variety of operations, and manual operation cannot Simultaneously, etc.

Embodiment Construction
[0040] Aiming at various difficulties in the pretreatment process of test samples in the current drug, food, health care product and cosmetic testing industries, the present invention provides a fully automatic test preprocessing device, which can be widely used in the drug analysis and testing industry, and some functions can also be used It is used in analysis and testing industries such as food, health care products and cosmetics. Fully automatic pretreatment before testing can be performed on various solid, semi-solid, and liquid dosage forms of drugs, as well as some foods and cosmetics. It can realize manual feeding and sampling, ultrasonic, stirring, temperature control, soaking, standing still to take supernatant, extraction, nitrogen blowing, temperature monitoring and early warning, light protection, and precise sampling (four different reagents can be added at the same time ), precision sampling, automatic rinsing, automatic cleaning and other functions. The invent...

The invention discloses an inspection pretreatment device and a pretreatment method. The inspection pretreatment device comprises a carrier platform; a processing unit, which is arranged on the carrier platform and has a chamber for reaction of a reagent to be tested; an ultrasonic vibration unit, which is arranged on the carrier platform and is used for carrying out ultrasonic vibration on the reagent in the processing unit; a stirring unit, which is used for stirring the reagent in the processing unit; and a sample adding and taking-out unit, which is used for adding a test sample into the processing unit and taking out the test sample from the processing unit. The device can realize various functions, such as manual feeding and manual sampling, ultrasonic, stirring, temperature control,soaking, standing and taking supernatant, extraction, nitrogen blowing, temperature monitoring and warning, light avoiding, precise sample adding, precise sample taking out, automatic rinsing and automatic cleaning, in the drug inspection pretreatment process; some functions are also suitable for inspection pretreatment of food, health care products and cosmetics; and the device and method can greatly improve medicine test efficiency.
Description
technical field [0001] The invention relates to an inspection preprocessing machine and a processing method, belonging to the field of drug analysis and detection. Background technique [0002] In the pharmaceutical, food, health care products and cosmetics testing industries, sample pretreatment is a very important link. Various solid dosage forms of medicines, whether it is tablets, capsules, granules, films of western medicine, or pills, powders of traditional Chinese medicine, etc.; various semi-solid dosage forms of medicines, whether it is suppositories, pastes, ointments, or gels Drugs in various liquid dosage forms, whether injections, solutions, sprays, emulsions, liniments, or suspensions, etc., usually require pretreatment to obtain the test solution used for detection. However, the pretreatment process is very professional, and the operation requirements are very high. The steps must be in a standardized order, the volume of reagents added must be accurate, and ...
