    摘要: A plasma concentrator for producing plasma concentrate from a plasma from which erythrocytes have been substantially removed. The device comprises a concentrating chamber having an inlet port and an concentrate outlet, the concentrating chamber containing hydrogel beads and at least one inert agitator; and a concentrate chamber having an inlet communicating with the concentrator outlet through a filter, and having an plasma concentrate outlet port. A process for producing plasma concentrate from plasma from which erythrocytes have been substantially removed, comprising the steps of a) moving the plasma into a concentrating chamber containing hydrogel beads and an agitator to form a hydrogel bead-plasma mixture; b) causing the agitator to stir the hydrogel bead-plasma mixture, facilitating absorption of water by the beads from the plasma, until a hydrogel bead-plasma concentrate is formed; and c) separating the plasma concentrate from the hydrogel beads by passing the plasma concentrate through a filter. The concentrator can be one or more syringe devices coupled for multiple concentrations.

    摘要: A dialysis system and a method for automatically priming a dialyzer are provided. The priming of the dialyzer is accomplished in two steps; namely, the use of a blood pump to prime a dialyzer followed by the use of the blood pump and a dialysate pump to prime the dialyzer. The dialysis system filters a fluid through an extracorporeal circuit, a balanced flow loop and a dialysate loop which is connected to the dialyzer. The dialysis system and method may prevent air or air bubbles from entering the blood stream of a patient during dialysmis. Moreover, the dialysis system may be, for example, a hemodialysis or peritoneal dialysis system.

    摘要: The present invention relates to the recovery of heat energy, e.g., the heat of compression, from the production of pressurized gases, in particular nitrogen (N2), but also other gases such as compressed dry air. This invention is directed to a system and method for increasing the efficiency in use of energy by recovering energy normally wasted in one device and using the energy in another device needing the energy. In particular, this invention is directed to recovering the heat of compression from a gas generation plant to warm cooling water that is also used as feed water to an ultra pure water generation plant.
