Description

Technical Field

[0001] This utility model relates to the field of clean bench technology, and in particular to a clean bench for cell processing. Background Technology

[0002] A laminar flow hood, also known as a clean bench, is designed to meet the cleanliness requirements of local working areas in modern industries, optoelectronic industries, biopharmaceuticals, and scientific research. It uses a fan to draw air into a pre-filter, which then passes through a static pressure box and enters a high-efficiency filter for filtration. The filtered air is then delivered in a vertical or horizontal airflow manner, ensuring that the operating area reaches a Class 100 cleanliness level and meeting the environmental cleanliness requirements for production. Laminar flow hoods are used when performing cell processing operations.

[0003] Chinese Patent Publication No. CN216936123U discloses a clean bench for stem cell processing, including a clean bench body with an operating chamber. An air inlet is located at the top of the operating chamber, and a filter is installed at the air inlet. A fan is installed above the filter, and an air outlet duct is installed below the operating chamber. An operating table is located at the bottom of the operating chamber, and an observation window is installed on the front of the operating chamber. An operating passage is provided between the bottom of the observation window and the operating table, and a stretchable and retractable sealing curtain is installed within the operating passage. Gloves are fitted on the sealing curtain. This clean bench for stem cell processing effectively isolates airborne contaminants such as suspended particles and bacteria, while increasing the operator's range of hand movement during operation, facilitating the processing of stem cells.

[0004] Traditional clean benches for cell processing lack auxiliary support structures, making it extremely strenuous for operators during long-term work. This greatly weakens the functionality of the workbench. Furthermore, the ventilation hoods on the workbench lack an effective positioning mechanism, making them prone to displacement and severely affecting their sealing performance. Utility Model Content
