Abstract: A flow passage design for multi-reaction biological detection includes a first temporary tank, a second temporary tank, a first microchannel, and a second microchannel. The first temporary tank is configured to temporarily store a first liquid in an initial state. The second temporary tank is configured to temporarily store a second liquid in the initial state. The first microchannel is located upstream of the first temporary tank. The first microchannel has an outlet end and an inlet end, respectively connecting to the first temporary tank and the second temporary tank. The second microchannel is located downstream of the first temporary tank and connects to the first temporary tank. In the initial state, a portion of the first liquid enters the second microchannel, the outlet end of the first microchannel is covered by the first liquid, and the inlet end of the first microchannel is covered by the second liquid.

Abstract: A blood plasma and blood cell separation device includes a first body, a blood plasma separation membrane and a second body. The first body has an injection port. The blood plasma separation membrane is disposed on the first body. The second body is movably assembled to the first body and has a collecting stage. The collecting stage has a collecting surface and a sampling recess on the collecting stage. When a blood enters the blood plasma separation membrane from the injection port of the first body, a blood plasma in the blood plasma separation membrane is separated by a capillary force between the collecting stage of the second body and the blood plasma separation membrane, and the blood plasma enters in the sampling recess by a relative movement between the first body and the second body.

Abstract: A numerical engineering model system is installed in a computer server and remotely operated by a local device via a network, which includes a user interface showing an operating page and receiving the numerical parameters, an analyzing module having at least one engineering model presented as the numerical parameters and a corresponding picture, a database storing the inputted numerical parameters and the picture, an engineering software means processing the inputted numerical parameters, and building, simulating and analyzing a 2D/3D model, and then storing the 2D/3D model, a simulating result and an analyzing result in the database. It is convenient for the users to remotely operate the system via any computer with network function. It simplifies the design procedures and reduces the design cost and design time because the engineering model is presented as numerical parameters and the corresponding picture. Furthermore, it is easy to understand and operate by common users without engineering knowledge.
