Abstract
A cartridge to be used for adsorption dialysis. A container having flexible walls are arranged to provide an inner space enclosing adsorption powder, comprising activated carbon, a phosphate adsorbent and a potassium ion adsorbent and other adsorbents. A sufficient amount of activated carbon is provided for adsorption of urea by the activated carbon. The cartridge forms a vacuum-packed transportation cartridge by generating a sub-pressure in the inner space, whereby the powder particles are immobilized and the cartridge becomes stiff. Before use, the cartridge is primed by introducing a liquid into the inner space, which introduction takes place at a low pressure. During use, dialysis solution is circulated through the cartridge, which is still exposed to a sub-pressure, whereby the flexible walls are sucked against the powder material. A peritoneal dialysis circuit comprises a filter, in which a primary circuit is formed with the filter and the peritoneal cavity and a secondary circuit is formed with the filter and the adsorbent cartridge.
