Automatic sample packaging mechanism based on sterility testing process

Abstract

The invention discloses a full-automatic sample subpackaging mechanism based on a sterility testing process. According to the full-automatic sample subpackaging mechanism, the controllability of the partial positions of hoses is realized by designing a special clamp for a bacteria collection bottle and a hose needle head of the bacteria collection bottle, mechanical arms are used for only grabbing a cultured product and a needle head clamp in the whole process, the bacteria collection bottle and the needle head are grabbed from a bacteria collection bottle tray by virtue of the two mechanical arms, the mechanical arms are precisely controlled by a servo motor to move the bacteria collection bottle together with the clamp to a push plate of a crank push rod mechanism for fixation, a needle head mechanical arm is used for moving the needle head and the clamp to an appointed position through a fixed route and strengthening the hoses, the three side-by-side hoses are put into a peristaltic pump groove and a flow-limiting groove by virtue of auxiliary mechanisms locate at a peristaltic pump and a flow-limiting device, and the flow limitation of any two of the three side-by-side hoses is realized by virtue of three coaxial cams. According to the full-automatic sample subpackaging mechanism, the problem that the positions of the hoses are unlikely to be determined is solved, the cam is creatively used for limiting the flow of the hoses, the whole flow limiting device is simplified, and the operation is convenient.

Description

technical field [0001] The invention belongs to the field of food and drug testing, and relates to a device for automatically distributing samples contained in a test product into three bacteria-collecting bottles and automatically adding corresponding medium. Background technique [0002] In recent years, many food and drug quality and safety incidents have occurred in my country, making the government and the public attach great importance to the quality assurance of food and drugs. As a key item of food and drug quality control, sterility inspection is clearly required in the latest 2010 edition of GMP "Good Manufacturing Practice for Drugs" and the 2015 edition of the Pharmacopoeia. It is an important item for enterprises and regulatory agencies to inspect qualified products. Routine sterility inspection installs a unidirectional airflow laminar flow table in a controlled environment, and places a bacterium collector on the laminar flow table to complete the sterility te...

AI Technical Summary

Problems solved by technology

Since the gap between the hoses is only 1 to 2 mm, the manual operation at this stage is mainly realized by limiting the flow one by one with the current limiting clamp, and it is easy to make mistakes. However, under the requirements of automation and the environment, such direct manual operation Methods and procedures are not allowed
