AI Technical Summary

Technical Problem

Existing culturing devices require frequent observation of cultured organisms, leading to potential damage and environmental changes, and are limited by complex system configurations and the inability to install high-resolution imaging due to the dual function of the imaging device as a lid, resulting in a large device size.

Method used

A culture apparatus with a single culture chamber, a drawer system for vessel access, and a compact optical unit for high-resolution imaging, utilizing gas supply for drawer operation and multiple heaters for environmental control, along with monitoring sensors and a buffering mechanism to minimize environmental disruption.

Benefits of technology

The solution allows for rapid environmental recovery, safe culture conditions, and high-quality imaging while maintaining a compact device size, reducing stress on cultured materials and enabling frequent observation without significant environmental changes.

Abstract

[Problem] The present invention addresses the problem of providing a culture device capable of managing the culturing environment of a plurality of culture vessels in a single culture chamber, suppressing an environmental change as much as possible, and rapidly performing restoration associated with environmental change inside the culture chamber. [Solution] A culture device comprises: a single culture chamber in which the environment (indicating gas concentration, temperature, humidity, and other atmospheres, and the same applies hereinafter) is maintained suitable for culturing; and an optical unit for observing an object to be cultured. The culture chamber has a drawer that allows access to culture vessels placed inside the culture chamber.
