Description

Technical Field

[0001] This utility model relates to the field of cell culture technology, specifically a carbon dioxide concentration monitoring system for a cell culture incubator. Background Technology

[0002] Cell culture incubators are advanced instruments for culturing cells, tissues, and bacteria. They can accurately provide parameters such as temperature, humidity, and gas environment required for cell culture. They are stable, responsive, and highly reliable, and can effectively prevent contamination of cultured cells. Maintaining a constant temperature inside the cell culture incubator is an important factor in maintaining healthy cell growth.

[0003] The patent application "202222956300.X" discloses a "carbon dioxide incubator capable of monitoring carbon dioxide concentration," which "includes a chamber body, with partitions fixedly connected to the top and bottom of the rear side of the chamber's inner cavity, a water tray fixedly connected to the bottom of the chamber's inner cavity, a control box fixedly connected to the top of the chamber's inner cavity, a first motor fixedly connected to the right side of the control box's inner cavity, and a threaded rod fixedly connected to the left side of the first motor's output end." This invention uses the threaded rod to cooperate with the first motor to control the position of the threaded sleeve and the disinfection shell, uses an atomizing nozzle to atomize and spray disinfectant, uses the housing to protect the second motor, and uses fan blades to cooperate with the second motor to spray the atomized disinfectant. This solves the problem that after the incubation work is completed, the incubator interior needs to be manually wiped with disinfectant, increasing the workload for staff.
