The subject invention pertains to the efficient and accurate detection and analysis of materials passing through a membrane. In a specific example the transport of materials through skin is analyzed. The subject method can allow accurate, precise, and specific real time measurements of compounds crossing a membrane. Accordingly, the subject method can save time in product development of pharmaceuticals, cosmetics, and protective clothing products, and can also reduce the need for animal and human testing.

Plasma fluid removal is needed in a variety of clinical conditions including congestive heart failure and moderate renal insufficiency. In order to avoid the problems inherent in extracorporeal ultrafiltration methods, the present invention removes fluid using an intravascular or intracorporeal dual-lumen catheter. Plasma fluid is driven across a semipermeable membrane, as in an in vivo vascular catheter. Suboptimal intracatheter flow, luminal collapse, erratic high transmembrane flow with nonhomogenous caking and clotting of the external catheter surface are all avoided by inducing pressure gradients across the wall by means of osmotic forces instead of negative pressures induced by hydraulic pumps. Osmotically induced fluid flow would tend to keep the lumena slightly distended and thereby simplify the fluid delivery systems. Osmotic gradients are maintained by utilizing dual lumen catheters typically placed in large central veins, and attached to pumps supplying high osmolality sterile solutions (such as dextrose or other sugars).

Disclosed herein are methods, systems and devices to monitor vascular volume status during renal replacement therapy utilizing at least one oximetry/photoplethysmography sensor. The methods, systems and devices provide an alternative to conventional vascular volume monitoring methods during renal replacement therapy while enabling reliable, non-invasive, and automatic monitoring of vascular volume to avert patient hypotension. The methods, systems and devices may be employed in the context of both inpatient and outpatient dialysis facilities and may also be incorporated into conventional hemodialysis and hemofiltration techniques and equipment.

This disclosure relates to blood treatment systems and related methods. The systems can include a blood pump arranged to move blood through a blood filter, a pressure sensor arranged to measure pressure of blood flowing through a fluid line between the blood pump and the blood filter, and a controller configured to activate a rinse pump to move rinse fluid through the blood filter based at least in part on the pressure of blood flowing through the fluid line as measured by the pressure sensor.
