Closed-type pre-treatment device for point-of-care testing of sputum.

ABSTRACT: The procedures and protocols for the pre-treatment of sputum specimens, mainly used for the diagnosis of pneumonia, are complex, labor intensive, and require skilled specialists working in a biosafety containment laboratory because of sample infectivity. In this study, we developed the first portable, low-power pre-treatment device that carries out all sputum pre-treatment procedures (liquefaction, homogenization, dissolution, and inactivation) in an enclosed space. Designed to simultaneously employ chemical and mechanical dissolution in the enclosed chamber, this device eliminates the risk of transmission and improves the effectiveness of sputum dissolution and pathogen detection. This device is expected to allow for the pre-treatment of infectious sputum specimens outside of a biosafety
