Patent number: 11291766Abstract: A pressure jacket for use with a fluid injector may have a pressure jacket body having a proximal end, a distal end, and a circumferential sidewall extending between the proximal end and the distal end along a pressure jacket longitudinal axis. The pressure jacket may further have at least one resiliently deflectable retaining member having a first segment attached to the pressure jacket body and a second segment protruding from the first segment toward the distal end of the pressure jacket body and deflectable relative to the first segment. The pressure jacket may further have at least one actuation member associated with the at least one resiliently deflectable retaining member. The at least one actuation member may interact with a housing of the fluid injector when the pressure jacket is connected to the housing to deflect the at least one resiliently deflectable retaining member upon rotation of the pressure jacket.Type: GrantFiled: October 28, 2016Date of Patent: April 5, 2022Assignee: BAYER HEALTHCARE LLCInventors: Michael J. Swantner, Richard A. Seman, Barry L. Tucker, Arthur E. Uber, III, Kevin P. Cowan, James A. Dedig, Christopher D. Capone

Publication number: 20180064866Abstract: A pressure sensor for use with a fluid delivery system having good sensitivity at low pressure, but also configured to remain in operating condition after being exposed to high pressures is disclosed herein. In one variation, the pressure sensor includes a fluid path set, a deformable element associated with the fluid path set and configured to deform in response to an external pressure, and a pressure transducer for monitoring deformation of the deformable element. In certain embodiments, the pressure sensor is configured to measure fluid pressure within the range of between about 0 mm Hg to about 300 mm Hg. However, the sensor pressure is also be configured to remain functional after being exposed to pressure in excess of about 60,000 mm Hg.Type: ApplicationFiled: November 6, 2017Publication date: March 8, 2018Inventors: MICHAEL A.

Patent number: 9669206Abstract: A fluid path set and method of use thereof is disclosed. The fluid path set includes a multi-patient fluid path section adapted for fluid connection to at least one pressurizing device, a per-patient fluid path section adapted for fluid connection with a patient, and a connector for removably and fluidly connecting the multi-patient fluid path section with the per-patient fluid path section. The connector includes a first connector member having an outer housing member and a first luer member recessed within the outer housing member, and a second connector member having a second threaded member and a second luer member recessed within the second threaded member. The first luer member and the second threaded member cooperate to securely and releasably connect the first connector member with the second connector member to establish removable fluid connection between the multi-patient fluid path section and the per-patient fluid path section.Type: GrantFiled: August 12, 2014Date of Patent: June 6, 2017Assignee: BAYER HEALTHCARE LLCInventors: Michael A.
