Patent number: 5853382Abstract: A system compact enough to be located entirely beside the donor's chair, and able to process the blood while the donor is still resting in the chair after having donated the blood. The separated blood components (plasma and red blood cells) may be stored in their individual optimum environments immediately after the whole blood is drawn, and the blood does not need to be transported back to a separation laboratory for processing. The system includes a needle (72) (or other cannula-like device) for insertion into a vein of the donor and drawing whole blood therethrough, a rotor (2a) for holding the blood after it is drawn, and a motor (50) for spinning the rotor so as to cause the blood to separate into components, for example, plasma and red blood cells. The system also provides for a container for collecting a separated component.Type: GrantFiled: June 13, 1996Date of Patent: December 29, 1998Assignee: Transfusion Technologies CorporationInventors: Gordon F. Kingsley, Thomas D. Headley, Lise N. Halpern

Patent number: 5733253Abstract: A system for separating a fluid having heavier and lighter components. The system includes a rotor having a rigid mounting member and an elastic diaphragm attached to the mounting member, the diaphragm defining a chamber. The system also includes a chuck for holding the rigid mounting member of the rotor and for spinning the rotor around an axis. The pressure of a control fluid, preferably a control gas, disposed adjacent the rotor's diaphragm is varied in order to control the volume of the rotor. Pressurizing the control gas causes fluid to flow out of the rotor; applying a vacuum to the diaphragm draws fluid into the rotor.Type: GrantFiled: October 13, 1994Date of Patent: March 31, 1998Assignee: Transfusion Technologies CorporationInventors: Thomas D. Headley, Edward T. Powers

Patent number: 5728060Abstract: A system for collecting and processing blood from a donor (70), wherein the system may be compact enough to be located entirely beside the donor's chair, and be able to process the blood while the donor is still resting in the chair after having donated the blood. Thus, the separated blood components (plasma and red blood cells) may be stored in their individual optimum environments immediately alter the whole blood is drawn, and the blood does not need to be transported back to a separation laboratory for processing. The system includes a needle (72) (or other cannula-like device) for insertion into a vein of the donor and drawing whole blood therethrough, a variable-volume rotor (2a) for holding the blood after it is drawn, and a motor (50) for spinning the rotor so as to cause the blood to separate into components, for example, plasma and red blood cells. The system also provides for a container for collecting a separated component.Type: GrantFiled: June 13, 1996Date of Patent: March 17, 1998Assignee: Transfusion Technologies CorporationInventors: Gordon F. Kingsley, Thomas D. Headley, Lise N. Halpern

Patent number: 5405308Abstract: An improved centrifuge rotor formed of a bowl body and core for blood processing applications, such as cell washing or pheresis, is described. A tubular core adapted to rotate with the rotor defines a processing region between the core and the interior of the bowl body. A plurality of projections extend into the processing region to minimize formation of fluid Coriolis waves which would otherwise cause undesirable turbulence.Type: GrantFiled: February 22, 1994Date of Patent: April 11, 1995Assignee: Haemonetics CorporationInventors: Thomas D. Headley, Jacques Chammas

Patent number: 5100372Abstract: An improved core member for a centrifuge bowl is described in which a plurality of small size circular openings are formed in the core member between a toroidal blood cell separation chamber and a collection chamber to provide fluid communication therebetween for collection of blood component in one flow direction and removal of stains in an opposite flow direction.Type: GrantFiled: October 1, 1991Date of Patent: March 31, 1992Assignee: Haemonetics CorporationInventor: Thomas D. Headley

Patent number: 4795448Abstract: A suction collection system particularly suitable for drawing fluids from a patient area and storing the fluids for later use or disposal, which is operable in any orientation of the device, thereby providing a field operable system which may be transported in battlefield conditions. The portable suction system consists of a cylindrical evacuating chamber with a top sealing cap. A suction port on the sealing cap is connected to the fluid collection bag, which consists of a laminar flexible plastic bag having an air permeable, liquid impermeable patch or portion through which air may pass for purposes of providing a vacuum suction, yet the collected fluids will remain in the bag. The suction power is provided by a vacuum pump which is electronically regulated by periodically energizing and de-energizing the pump to conserve power supply energy.Type: GrantFiled: December 30, 1987Date of Patent: January 3, 1989Assignee: Haemonetics CorporationInventors: Gary R. Stacey, Wesley H. Verkaart, Thomas D. Headley, Edward T. Powers
