AI Technical Summary

Problems solved by technology

However, these devices are limited to only being able to inspect small surfaces, typically less than 1mm 2
Therefore, implementing the technique to detect one or more assay media, such as membranes or agar media, is time-consuming and expensive due to the several minutes required to observe each square centimeter and the necessity of using a scanning system

Abstract

The incubation and detection device includes a heater, a detection surface with at least one receptacle including a growth medium, and a detection system. There is also a system for preventing the formation of condensation in the receptacle, which includes a temperature-control formed by temperature sensors, heaters, coolers, and management device capable of collecting and analyzing the information collected by the sensor and controlling the heater and cooler so as to generate the desired incubation temperature and permanently apply a temperature gradient to the surface of the receptacle.

Description

technical field [0001] The invention relates to the field of detection of growth stages of microorganisms. [0002] The present invention is mainly applied in the field of industrial and clinical microbiology, such as pharmacy, biotechnology, agricultural product industry or in hospitals or medical analysis laboratories. [0003] In particular, the invention relates to a device for the cultivation and rapid detection of the presence of microorganisms in a sample as colonies formed on the surface of a membrane or a solid or semi-solid medium. Background technique [0004] Currently, many techniques are available to detect contaminants, such as bacteria, in the samples to be tested. [0005] The most common and oldest method involves precipitation on the surface of an agar medium that is more or less selective for one or several types of microorganisms. [0006] The medium is then incubated for up to several days at the appropriate temperature required for microbial growth. ...
