Patent number: 11583621Abstract: 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.Type: GrantFiled: May 27, 2016Date of Patent: February 21, 2023Assignee: TRIOMED ABInventors: Anders Wallenås, Nina Meinander, Carin Malmborg, Stefan Landholm, Hans Bengtsson

Publication number: 20220162893Abstract: A method for operating a cargo door of an aircraft. The method comprises, opening the cargo door inwardly in relation to a cargo door opening by pivoting the cargo door to an open position adjacent a ceiling of a cargo space. The cargo door is supported by a door frame during opening of the cargo door. The method further comprises, moving the cargo door in relation to the door frame to a position wherein the cargo door opening is substantially free from the cargo door. The cargo door is supported by a support frame, moveable in relation to the door frame, during this movement. The invention also concerns a device for operating a cargo door of an aircraft.Type: ApplicationFiled: March 19, 2020Publication date: May 26, 2022Applicant: SCANDINAVIAN CARGOLOADING TECHNOLOGIES ABInventors: Anders WALLENÅS, Hans BENGTSSON

Publication number: 20200338251Abstract: Method and apparatus for ultrafiltration of a patient being overhydrated due to congestive heart failure, comprising a cassette having four inlets/outlets. A patient tube is connected to a patient connector, intended to be connected to a patient line for access to a peritoneal cavity of the patient. The patient tube comprises a flow pump for addition and removal of a peritoneal fluid between the cassette and the peritoneal cavity. The fluid is introduced into an intermittent bag controlled by an intermittent valve and then returned the same way back to the peritoneal cavity. Glucose is metered into the fluid entering the peritoneal cavity by means of a glucose pump. Glucose is replenished continuously or intermittently for keeping a concentration of the osmotic agent substantially constant in the peritoneal cavity. After treatment, the peritoneal fluid is drained to a drain bag, wherein the drain tube comprises a drain valve and an albumin filter.Type: ApplicationFiled: July 9, 2020Publication date: October 29, 2020Applicant: TRIOMED ABInventors: Anders WALLENÅS, Lars WRAMNER, Stefan LANDHOLM

Publication number: 20200164129Abstract: A dialysis device comprising a dialysis circuit for providing dialysis fluid and returning purified fluid to the dialysis circuit. The device comprises an evaporator/condenser device, provided with an evaporator bag and a condenser bag. The evaporator bag receives dialysis fluid from the dialysis bag and produces steam, whereby a concentrated dialysis fluid is left and drained to a drain bag. The condenser bag receives the steam produced in the evaporation bag and condenses the steam for producing pure water for being returned to said dialysis circuit. The evaporation and condensation takes place at a subatmospheric pressure, such as between 30 and 70 mmHg at a temperature of about 30 to 44° C. Heat energy is provided to the evaporation bag and the condenser bag is cooled. The cooled energy may be absorbed by a heat pump for delivery of heat to the evaporator bag.Type: ApplicationFiled: July 13, 2018Publication date: May 28, 2020Applicant: TRIOMED ABInventor: Anders WALLENÅS

Patent number: 8282828Abstract: A method and a system for regenerating a body fluid, such as a peritoneal dialysis fluid. The body fluid is removed into an extracorporeal circuit comprising an electrofilter for removing charged ions from the body fluid, a nanofilter for removing large molecules, such as Dextran 40, and a reverse osmosis filter for concentrating the body fluid, for producing a synthetic urine to be discarded. The removed ions and large molecules are returned to the patient together with pure water from the reverse osmosis filter through an ultrafilter.Type: GrantFiled: August 16, 2007Date of Patent: October 9, 2012Assignee: Triomed ABInventor: Anders Wallenås
