Publication number: 20230389919Abstract: A one-handed automatic suturing device with a needle-transfer of a double-ended needle includes a first and a second jaw element that are movable in relation to each other between an open position and a closed position. The first jaw element has an alternating mechanism for alternating, each time the jaw elements are moved to the closed position, between: a retaining position, wherein the alternating mechanism is configured to retain a first end of the double-ended needle with a first retention strength; and a releasing position, wherein the alternating mechanism is configured for releasing said needle. The second jaw element has a holding mechanism for retaining and releasing a second end of the double-ended needle; wherein the holding mechanism is configured to retain the second end of the double-ended needle with a second retention strength that is lower than the first retention strength.Type: ApplicationFiled: October 25, 2021Publication date: December 7, 2023Inventors: Gabriel Börner, Hans Bengtsson

Patent number: 11590269Abstract: An apparatus for ultrafiltration of a patient being overhydrated due to congestive heart failure, comprising a tube set including a connector (21) for connection to a patient line (3) for access to the peritoneal cavity of the patient. A flow pump (41-43) is arranged for addition and removal outflow and inflow (recirculation) of fluid from/to the peritoneal cavity. An osmotic agent peristaltic pump (16) is arranged for replenishment of glucose solution to the fluid added to the peritoneal cavity for promoting ultrafiltration. The glucose is replenished intermittently for keeping a concentration of glucose substantially constant in the peritoneal cavity. The flow pump comprises a pressure chamber (43) with rigid walls and a flexible pump bag (41) arranged therein. An air pump (45) pressurizes the chamber for outflow of fluid from the peritoneal cavity by a sub pressure and inflow of fluid to the peritoneal cavity by an overpressure, which pressures are maintained within safe limits.Type: GrantFiled: February 27, 2020Date of Patent: February 28, 2023Assignee: TRIOMED ABInventors: Mikael Axelsson, Stefan Landholm, Eva Persson, Hans Bengtsson

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

Patent number: 10946130Abstract: An apparatus for ultrafiltration of a patient being overhydrated due to congestive heart failure. The apparatus comprises a dilution syringe for removal of a portion of peritoneal fluid from the peritoneal cavity. A glucose bag comprises glucose concentrate at a concentration of 30%. A small amount of glucose concentrate is mixed with the dilution fluid in the dilution syringe in order to dilute the glucose concentrate to below 3% concentration. Then, the mixture is filled into the peritoneal cavity from the dilution syringe in order to replenish the glucose in the peritoneal cavity for maintaining a substantially constant glucose concentration in the peritoneal cavity. In addition, peritoneal fluid is intermittently removed from the peritoneal cavity for counteracting increased intraperitoneal fluid volume and increased intraperitoneal pressure due to ultrafiltration. A UF bag is arranged for receiving such surplus peritoneal fluid. A glucose syringe may be arranged for metering the glucose concentrate.Type: GrantFiled: August 26, 2016Date of Patent: March 16, 2021Assignee: TRIOMED ABInventor: Hans Bengtsson

Patent number: 6078390Abstract: An optical scanning system uses a low-resolution scanning operation, to automatically adjust the sensitivity of the system. The system performs a low-resolution scanning operation by scanning a line, automatically and iteratively setting the levels of excitation signal power and detector gain, skipping a plurality of lines and scanning a next line, adjusting the levels as appropriate, skipping a plurality of lines and scanning a next line, and so forth. After the system sensitivities have been set, the calibrated system then scans all the lines of the sample to collect data. The calibrated system thus scans for the first time the lines that were skipped during the low resolution scanning operation.Type: GrantFiled: May 4, 1998Date of Patent: June 20, 2000Assignee: General Scanning, Inc.Inventor: Hans Bengtsson

Patent number: 6075613Abstract: An optical scanning system includes a power meter that during calibration operations is illuminated by an attenuated excitation beam. The power meter measures optical power in the attenuated excitation beam at various index settings of a variable optical attenuator, and the system constructs a lookup table that relates incident excitation beam power to the index settings of the attenuator. The system then uses the table to select the appropriate setting for the attenuator in order to deliver to the sample an excitation beam of a specified optical power. The system calibrates the gain of a detector by redirecting, or reflecting, the excitation beam of known intensity to the detector. A photometric device in the detector produces a signal that is proportional to the intensity of the beam at various gain settings. The system then produces a lookup table that relates the gain settings to the actual gain of the detector, that is, to the ratio of the known incident power to the detector readings.Type: GrantFiled: February 26, 1999Date of Patent: June 13, 2000Assignee: General Scanning, Inc.Inventors: Mack Schermer, Hans Bengtsson, Markus Weber
