Abstract: A priming indicator for a fluid infusion system includes a luer cap or other component of the infusion system having an indicator surface covered by a membrane. The membrane exhibits a first visual characteristic, such as being opaque, when dry and exhibits a second characteristic, such as becoming less opaque, when wet. Once the membrane becomes wet, indicia on the surface, which may be provided on a rod at least partially covered by the membrane, becomes visible, thereby indicating an intravenous tube to which the luer cap is secured has been primed or is nearly primed. The indicator may alternately be employed at an upstream end of an infusion set, such as at the port of a medical bag providing a supply of fluid, to indicate a low level of fluid in the medical bag.

Abstract: Membranes are made from polymers and heat treated so that they have at least two zones with pores of different sizes. Pores with a smaller size have a lower molecular weight cut off than pores with a larger size. Zones with pores of different sizes may also be made by coating portions of membranes with polymer coatings. Membranes with pores of different sizes may be used in dialyzers for hemofiltration, hemodiafiltration, and other hemodialysis procedures. The membranes may also be used in other separation processes.

Abstract: A medical device, such as a vascular access device, is disclosed for providing access to a medical fluid flow path for the introduction or withdrawal of medical fluids to and from the flow path. The access device includes an indicator for providing a visual indication when the access device has been exposed to an antiseptic agent.
