Pressure Output Device For Extracorporeal Hemodialysis Machine |
摘要 |
A pressure output device (POD) assembly for sensing fluid pressure in a fluid processing system, is provided. This POD assembly includes a shell defining a shell interior, and a movable diaphragm disposed in the shell interior and separating the shell interior into a flow-through chamber and a pressure sensing side. A sensor port is in fluid communication with the pressure sensing side. An inlet port and an outlet port are in fluid communication with the flow-through chamber. The inlet port and the outlet port define an inlet and an outlet, respectively, of a flow-through channel that passes through the flow-through chamber. A boss protrudes from the interior wall of the shell and extends into the flow-through channel to prevent occlusion of flow under different pressure conditions within the flow-through chamber. |

1. A pressure output device for sensing fluid pressure in a fluid processing system, the pressure sensing device comprising:
a shell defining a shell interior; and a movable diaphragm disposed in the shell interior and separating the shell interior into a flow-through chamber defined by a lower portion of the shell and a first side of the diaphragm, and a pressure sensing chamber defined by an upper portion of the shell and a second side of the diaphragm, the second side being opposite the first side, the shell further defining a sensor port in fluid communication with the pressure sensing chamber, an inlet port in fluid communication with the flow-through chamber, and an outlet port in fluid communication with the flow-through chamber, wherein the inlet port and the outlet port define an inlet and an outlet, respectively, of a fluid flow path through the flow-through chamber, and the flow-through chamber has an interior wall and comprises a boss along the interior wall, which prevents the diaphragm from occluding flow through the fluid flow path. |
