Publication number: 20240123128Abstract: A fluid treatment plant has a filter module including at least a first filter and a second filter connected in series and connectable to a supply of fluid. A pump is fluidly connected to the filter module and a controller with a fluid quality sensor is connected to detect a quality of the fluid between the first filter and the second filter. A filter module detector is connected to the controller configured to uniquely detect a filter module connected to the pump, and the controller is controls the pump responsively to a signal from the fluid quality sensor and the module detector. The controller is configured to continue pumping based on output of the quality sensor and/or based on output from the filter module detector.Type: ApplicationFiled: December 27, 2023Publication date: April 18, 2024Applicant: NxStage Medical, Inc.Inventors: Jeffrey H.

Patent number: 11648179Abstract: A top for a plasma storage container includes a top body that defines the structure of the top and seals an opening of the plasma storage container. The top also includes a first opening and a vent opening extending through the top body. A valve mechanism is located at least partially within the top body and includes an aperture therethrough. The aperture opens upon connection of a blunt cannula to provide access to the interior of the plasma storage container. The top also includes a vent filter. The vent filter allows air to vent through the vent opening during plasma collection.Type: GrantFiled: October 16, 2018Date of Patent: May 16, 2023Assignee: Haemonetics CorporationInventors: Christopher S.

Patent number: 11559464Abstract: A top for a plasma storage container includes a top body that defines the structure of the top and seals an opening of the plasma storage container. The top also includes a first opening and a vent opening extending through the top body. A septum is located at least partially within the first opening and includes an aperture therethrough. The septum allows a blunt cannula to pass through the aperture to access the interior of the plasma storage container. The top also includes a hydrophobic membrane located on underside of the top body. The membrane covers the vent opening and allows air to vent through the vent opening during plasma collection.Type: GrantFiled: May 16, 2017Date of Patent: January 24, 2023Assignee: Haemonetics CorporationInventor: Christopher S.

Patent number: 11446417Abstract: A treatment system for performing a treatment on a patient may include a treatment fluid preparation device having a pump connected by a fluid channel to a reservoir of a source fluid, the pump conveying the source fluid from the reservoir, through a filter, and combining the source fluid with a concentrate by pumping the source fluid with the concentrate to form a treatment fluid in a batch container. The treatment fluid preparation device may have a controller that controls a heater, the pump, and a memory. The controller starts the heater to warm the treatment fluid in the batch container at a time that is responsive to the treatment time stored in the memory. The controller also detects a pressure property of the filter to determine its integrity and outputs an indication of a failed batch if the pressure property indicates the integrity of the filter is insufficient.Type: GrantFiled: October 18, 2018Date of Patent: September 20, 2022Assignee: NxStage Medical, Inc.Inventors: Jeffrey H.

Patent number: 10130746Abstract: Systems, methods, and devices for preparation of water for various uses including blood treatment are described. In embodiments, fluid is passed through a first filtration step which is effective for creating purified water and a pair of ultrafilters placed at the outlet. The ultrafilters are separated by an intervening flow path to prevent grow-through from the outlet end upstream. In embodiments, a recirculation path with an air removing filter helps to eliminate air from the ultimate product water.Type: GrantFiled: June 28, 2016Date of Patent: November 20, 2018Assignee: NxStage Medical, Inc.Inventors: Jeffrey H.

Patent number: 9928457Abstract: A method for securing an RFID tag to an object includes providing an RFID tag and placing the RFID tag on the object. The RFID tag has an RFID chip and an antenna electrically connected to the RFID chip. The RFID tag also has a first and second opening extending through the RFID tag. The object has a first and second protrusion extending from a surface of the object. The first and second protrusions extend through the first and second openings when the RFID tag is placed on the object. The method also includes melting the first and second protrusions to create a single integral boss that covers at least a portion of the RFID tag and secures the RFID tag to the object. The chip may be nonfunctional prior to the securement process.Type: GrantFiled: June 16, 2014Date of Patent: March 27, 2018Assignee: Haemonetics CorporationInventor: Christopher S. McDowell
