Title:
MICROFLUIDIC DEVICE AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
WIPO Patent Application WO/2020/253647
Kind Code:
A1
Abstract:
A microfluidic device comprising: a first substrate (402,502,602,702,802) having a first assembling side (402a,702a, 802a); and a second substrate (404,504,604,704,804) having a second assembling side(404a, 504a, 604a, 804a ) connectable with the first assembling side (402a,702a, 802a) to assemble the first substrate (402,502,602,702,802) and the second substrate (404,504,604,704,804) together. At least one of the first assembling side (402a,702a, 802a) and the second assembling side (404a, 504a, 604a, 804a ) has a fluid chamber channel (406,706,806), and after the first substrate (402,502,602,702,802) and the second substrate (404,504,604,704,804) are connected together, the fluid chamber channel (406,706,806)forms a fluid chamber having a fluid inlet (408,608,708,808)and a fluid outlet(410,510,610,710,810). The at least one of the first assembling side(402a,702a, 802a) and the second assembling side(404a, 504a, 604a, 804a ) having the fluid chamber channel (406,706,806)has an outlet expansion groove (418,518,618,718,818, 818')adjacent to and extending downstream from the fluid outlet (410,510,610,710,810), and wherein at the fluid outlet (410,510,610,710,810), an outer peripheral profile of the outlet expansion groove (418,518,618,718,818, 818') is located outside an outer peripheral profile of the fluid outlet (410,510,610,710,810).
