Publication number: 20190184076Abstract: Apparatus for blood processing comprising a blood collection reservoir (30), a blood collection conduit, a blood transfer conduit, and a manually operable pump unit (10) comprising first and second peristaltic pumps (10A, 10B). The first peristaltic pump is mounted about and acts upon the blood collection conduit. The second peristaltic pump is mounted about and acts upon the blood transfer conduit. The pump unit is provided with an actuator (112) adapted to switch the second peristaltic pump between an operative condition and an inoperative condition: in the operative condition the second peristaltic pump is engaged with the blood transfer conduit to convey blood from the blood collection reservoir while the first peristaltic pump is engaged with the blood collection conduit to convey blood from a wound site to the blood collection reservoir, and in the inoperative condition the second peristaltic pump is disengaged from the blood transfer conduit.Type: ApplicationFiled: September 7, 2017Publication date: June 20, 2019Inventor: Terence GOURLAY

Patent number: 10172981Abstract: A device for the concentration of a mixture of fatty material and aqueous fluid comprises a chamber for receiving a mixture of fatty material and aqueous fluid, and a body of absorbent material, the chamber being separated from the absorbent material by a barrier member having at least one opening, and a shutter element movable from a closed position, in which said opening is occluded, to an open position, in which said opening permits fluid flow from the chamber to the absorbent material. It has been found that the use of an absorbent material enables fatty material to be concentrated to the required degree in a passive, single vessel process without damage to the fatty tissue. There are also described methods for the use of the device.Type: GrantFiled: January 6, 2014Date of Patent: January 8, 2019Assignee: Brightwake LimitedInventor: Terence Gourlay

Patent number: 9636446Abstract: The present invention relates to a system, apparatus, and method for separating components of a fluid, e.g. blood, which eliminates the need for expensive hardware and produces a stabilized waste product. The system comprises an apparatus or device (V) for separating components of a fluid (15?) comprising a container (5?) having at least one separation or filtration member (10?) capable of selectively separating or filtering at least one component from the fluid, and a superabsorbent material (20?) capable of absorbing the at least one component separated from the fluid, and thereby providing a processed fluid free or substantially free of said at least one component; and agitation means.Type: GrantFiled: May 18, 2009Date of Patent: May 2, 2017Assignee: University of StrathclydeInventor: Terence Gourlay

Publication number: 20160158425Abstract: A disposable blood transfer conduit is used in association with a pump drive unit, a blood collection vessel and a blood concentration device. The blood transfer conduit comprises a blood transfer tube (13) and a peristaltic pump element (12) having an enclosed housing mounted about the blood transfer tube (12). At least part of the blood transfer tube (13) is resiliently deformable and extends through the enclosed housing of the peristaltic pump element (12). The disposable blood transfer conduit may be used in the concentration of blood for autologous blood transfusion.Type: ApplicationFiled: July 23, 2014Publication date: June 9, 2016Inventors: Stephen COTTON, Terence GOURLAY
