A circuit board for body fluid collection includes a belt-like supporting substrate, and a plurality of measurement units defined in the supporting substrate along the longitudinal direction of the supporting substrate. Keywords include HAVi, Widgets, and BD platform. Moreover, a series of therapeutic procedures can be automated. The at-least-one brake-fluid-accumulating piston bore is fluidly connected to the brake fluid orifice. According to one embodiment, the distorted outlet members are characterized by an outer convex shape.
