Publication number: 20230172542Abstract: Disclosed herein is a system, apparatus and method directed to patient temperature control. The system can include a control module configured to provide fluid that is heated or cooled, a heating and cooling system configured to couple with the control module and receive the fluid, and a temperature sensor coupled to the control module, the temperature sensor configured to measure a body temperature of a patient and provide signals to the control module that indicate the body temperature. The system can include a neurostimulation device coupled to the control module to provide neurostimulation to the patient. The control module can include logic, stored on non-transitory, computer-readable medium that, when executed by one or more processors, causes performance of operations including generation and transmission of first instructions to the neurostimulation device causing initiation of a first neurostimulation procedure.Type: ApplicationFiled: May 11, 2021Publication date: June 8, 2023Inventors: Jeff Baker, Patrick Downie, Jesse Smith, Eric A. Fallows, Michael Yarger, David Bostick

Patent number: 11344851Abstract: A biological fluid separation device adapted to receive a biological fluid sample having a first portion and a second portion is disclosed. The device includes a housing having a first chamber having a first chamber inlet for receiving the biological fluid sample therein and a first chamber outlet. The housing has a second chamber having a second chamber inlet and a second chamber outlet, and a separation member separating at least a portion of the first chamber outlet and the second chamber. The separation member is adapted to restrain the first portion of the biological fluid sample within the first chamber and to allow at least a portion of the second portion of the biological fluid sample to pass into the second chamber. An actuator, such as a vacuum source, draws the biological fluid sample into the first chamber and the second portion into the second chamber.Type: GrantFiled: October 21, 2019Date of Patent: May 31, 2022Assignee: BECTON, DICKINSON AND COMPANYInventors: Qihua Xu, Kristin Weidemaier, Christopher Basciano, Sivaramakrishnan Balasubramanian, Patrick Downie

Patent number: 10064574Abstract: A flow regulator for a blood collection assembly includes a housing having an inlet and an outlet, which defines an interior space between the inlet and the outlet. A membrane having a first surface and a second surface is disposed at least partially within the interior space. The membrane has a first position where a flow path between the inlet and the outlet is substantially open, and a second position where the flow path between the inlet and the outlet is at least partially restricted. The membrane is configured to move between the first and second positions in response to a pressure differential acting on the membrane.Type: GrantFiled: January 9, 2013Date of Patent: September 4, 2018Assignee: Becton, Dickinson and CompanyInventors: Patrick Downie, Jamieson W.
