Publication number: 20220276220Abstract: Embodiments are described for separating collecting components from a multi-component fluid such as whole blood. Some embodiments provide for controlling the amount of a component, such as platelets, introduced into a separation chamber to ensure that the density of fluid in the separation chamber does not exceed a particular value. This may provide for collecting purer components. Other embodiments may provide for determining a chamber flow rate based on a concentration of a component in the multi-component fluid, which may then be used to determine a centrifuge speed, to collect purer concentrated components.Type: ApplicationFiled: May 16, 2022Publication date: September 1, 2022Inventors: Marlene BAINBRIDGE, Todd Curtis GREEN, Logan FENDER

Patent number: 7354415Abstract: Methods and apparatus particularly involving the separation of blood into blood components and the collection of such components are disclosed. In one aspect, an extra-corporeal method for the collection of plasma and red blood cells is provided, wherein the collection of plasma and red blood cells may occur simultaneously or subsequently utilizing the same dual stage blood processing vessel. The flow of blood to the blood processing vessel and return of uncollected blood components may be provided via a single needle, wherein blood is removed from and returned to a donor/patient during alternating blood removal and blood return submodes. Platelet separation and collection options are also described. In either case, prior to red blood cell collection, a set-up phase may be carried out to set a predetermined hematocrit and AC ratio. Replacement fluid delivery may optionally also be provided either substantially continuously during any collection phase(s) and/or in a bolus mode.Type: GrantFiled: April 20, 2004Date of Patent: April 8, 2008Assignee: Gambro BCT, Inc.Inventors: Marlene Bainbridge, Muriel Keller, Timothy M.

Publication number: 20070232980Abstract: This invention provides an apparatus and method for controlling a fluid separation system, preferably a blood apheresis system, by sensing fluid pressure and comparing the sensed fluid pressure to a threshold value.Type: ApplicationFiled: June 11, 2007Publication date: October 4, 2007Applicant: GAMBRO BCT, INC.Inventors: Thomas FELT, Marlene BAINBRIDGE

Publication number: 20070093774Abstract: This invention provides a method for controlling a fluid separation system, preferably a blood apheresis system having a leukocyte reduction chamber. The method utilizes at least a two-level alarm system. A first-level alarm condition is triggered in response to a pressure drop in the system to less than or equal to a specified system pressure and pauses fluid flow in at least a portion of the system. A second-level alarm condition is triggered in response to a specified number of said pressure drops within a specified period and reduces the flow rate of the fluid in the system. The alarm conditions may also trigger a visible and/or audible alarm. These alarm levels permit flow through the leukocyte reduction chamber to continue when the pressure drop is caused by a non-serious, self-resolving or easily-correctable condition such as misalignment of system components.Type: ApplicationFiled: September 8, 2006Publication date: April 26, 2007Applicant: GAMBRO, INC.Inventors: Thomas Felt, Marlene Bainbridge

Publication number: 20070078368Abstract: This invention provides a method for controlling a fluid separation system, preferably a blood apheresis system having a leukocyte reduction chamber. The method utilizes a return-flow alarm system. A return-flow alarm-triggering pressure is specified, and when pressure of the return flow in the system is higher than or equal to the specified pressure, a return-flow alarm is triggered.Type: ApplicationFiled: September 8, 2006Publication date: April 5, 2007Applicant: GAMBRO, INC.Inventors: Thomas Felt, Marlene Bainbridge

Publication number: 20070004997Abstract: This invention provides a method for controlling a fluid separation system, preferably a blood apheresis system having a leukocyte reduction chamber. The method utilizes a three-level alarm system. A first-level alarm condition is triggered in response to a pressure drop in the system to less than or equal to a specified system pressure and pauses fluid flow in at least a portion of the system. A second-level alarm condition is triggered in response to a specified number of said pressure drops within a specified period and reduces the flow rate of the fluid in the system. The alarm conditions may also trigger a visible and/or audible alarm. These alarm levels permit flow through the leukocyte reduction chamber to continue when the pressure drop is caused by a non-serious, self-resolving or easily-correctable condition such as misalignment of system components.Type: ApplicationFiled: September 8, 2006Publication date: January 4, 2007Applicant: GAMBRO, INC.Inventors: Thomas Felt, Marlene Bainbridge

Patent number: 6899691Abstract: A method and apparatus for controlling a fluid separation system in response to fluid pressure changes in a fluid flow, said method comprising the steps of sensing a fluid pressure; comparing the fluid pressure to a threshold value, and if the fluid pressure is below the threshold value, then pausing fluid flow for a selected period. During the selected period, either the fluid pressure sensed automatically resolves or the method further comprises a step of setting a fall alarm condition. The method and apparatus may further include interpreting a particular quantity of below threshold fluid pressure occurrences where the fluid pressure is below the threshold value occurring within a particular time period, and then, signalling an alarm. Threshold values may be calculated by the method or apparatus according to a formula such as the following: Threshold Value=Config+75?0.3309*Qin/(1?Hin)?0.Type: GrantFiled: December 22, 2000Date of Patent: May 31, 2005Assignee: Gambro Inc.Inventors: Marlene A.

Patent number: 6773413Abstract: An extracorporeal blood processing method includes a set-up phase establishing certain conditions in blood being processed prior to separation of the blood into components. Also, a blood processing method contemporaneously extracts selected multiple blood components from a blood processing vessel. Blood is separated into components in the blood processing vessel in a centrifugal field.
