Patent number: 12270807Abstract: A reacting device of dual path synchronous immunochromatographic platform includes a seat, an upper housing, and a fluid dividing funnel. The seat contains two immunochromatographic carriers. The hollow pipe portion has two sloped structures. A force bearing portion of the fluid dividing funnel can be pressed down, so two fluid exits of the fluid dividing funnel move towards these two sloped structures. The specimen drops and is guided into these two immunochromatographic carriers respectively. A reaction result can be observable. The fluid dividing funnel can divide the specimen into two immunochromatographic carriers evenly. The sloped structure can increase the accuracy of specimen supply. Excess specimen can be scraped off for enhancing the solving accuracy. In addition, it can decrease the possibility of false positive problem.Type: GrantFiled: July 4, 2021Date of Patent: April 8, 2025Assignee: TAICHUNG VETERANS GENERAL HOSPITALInventors: Ming-Feng Wu, Hui-Chun Chang, Jing-Lian Jheng, Yi-Yun Hung, Jen-Ying Li, Hui-Chen Chen, Jiunn-Min Wang
