Portable continuous automatic preparation device and portable continuous automatic preparation method for agar medium containing temperature-sensitive active substance

Abstract

The invention discloses a portable continuous automatic preparation device and a portable continuous automatic preparation method for agar medium containing a temperature-sensitive active substance. The portable continuous automatic preparation device for agar medium containing a temperature-sensitive active substance comprises a thermal insulation and supporting housing unit, a multi-specification culture dish fixing and pushing unit, an electric control unit, a constant-temperature storage and agitating unit, an intermittent rotating unit, an automatic continuous pouring unit, and a disinfection and sterilization unit. According to the invention, the portable continuous automatic preparation device for agar medium containing a temperature-sensitive active substance is of a disassemblableportable design, the design is small, the portable continuous automatic preparation device for agar medium containing a temperature-sensitive active substance can be completely placed for operation under a spatially limited environment, such as a clean bench, the seven units operate in coordination, and can effectively ensure the constant-temperature quantitative pouring of an active substance, and thereby the requirement for the uniformity of medical and biological experiments is met. The invention fills the gap of continuous pouring devices for multiple specifications of agar media containing temperature-sensitive active substances applicable to laboratories in China.

Description

technical field [0001] The invention relates to the field of biological or medical experimental equipment, in particular to a portable continuous automatic preparation device and method for agar medium containing temperature-sensitive active substances. Background technique [0002] The preparation of agar plate medium commonly used in medical and biological experiments needs steps such as weighing, pressure steam sterilization, pouring and subpackaging. Excessively high temperature will easily destroy the activity of temperature-sensitive substances, and low temperature will cause agar to solidify, and most of the agar starts to solidify at about 40°C, and the solidified agar needs to be heated to 95°C before it starts to melt. Therefore, some special agar medium And antibacterial experiments often need to add blood, serum, antibiotics, indicator bacteria and other heat-sensitive substances to constant temperature agar at about 45°C to prepare agar medium containing tempera...

AI Technical Summary

Problems solved by technology

[0004] (1) The production batch of large-scale medium preparation equipment in factory is large, but the types of medium produced are small, which cannot meet the requirements of the laboratory on the variety and content of temperature-sensitive substances due to the diversity of experimental samples.

[0005] (2) Small-scale preparation equipment cannot achieve continuous automatic pouring, and there is no plate fixing device that can fix multiple plates at the same time and the size can be adjusted, so the work efficiency is low
