摘要：
A pressure measurement pod for blood circuits can include a flexible, moveable, fluid-impermeable diaphragm and can be formed via either a one-shot or a two-shot molding process. A method of manufacturing a pressure measuring device can include providing first and second major mold parts having recesses defining major parts of a housing, and inserting pins in the first and second major mold parts, the pins being shaped to define a flow channel of a molded pressure measuring pod. One of the pins may have a major face that defines an internal surface of a diaphragm. The method may further include closing the first and second major mold parts with the pins therebetween and injection molding a pressure pod housing. Finally, the pressure pod is removed from the mold parts and the pins are withdrawn from the flow channel.
