| abstract | (57) [Summary] A supply device includes a first chamber for containing a penetrant, a membrane for forming a wall of the first chamber for sucking a fluid by an osmosis phenomenon, and a second chamber for containing an effective substance for supply. And a movable piston separating the two chambers. An orifice having a slit valve is in liquid communication with the second chamber. In the presence of pressure, the active substance pushes the slit, opening the passage for the supply of the active substance and forming a flow. If there is no flow (or if the pressure is below the pressure required to open the slit), the slit remains closed, so there is no back diffusion of the external fluid, and thus the active substance in the second chamber is It is not contaminated by. In addition, when the slit is closed, the active substance is also prevented from diffusing forward from the capsule. The slit valve only opens to the minimum size required for the flow generated by osmotic pumping. The slit valve also forms a flow path around the obstacle to prevent clogging even when there is an obstacle in the slit valve. |
