20090254049 | SYSTEMS AND METHODS FOR PROVIDING AN AUTOMATIC OCCULSION DEVICE - An auto-occlusion safety device is provided for use in preventing rupture of infusion components during rapid infusion procedures. An occlusion valve is disclosed having a threshold pressure that is less than a rupture tolerance of the infusion system components. As the fluid pressure of the infusion system increases beyond the threshold pressure of the occlusion valve, the occlusion valve is automatically activated thereby occluding fluid flow upstream from a vulnerable infusion component. An accumulator is further disclosed for use in combination with the safety device to compensate for time delays in full activation of the occlusion valve. | 10-08-2009 |
20090287186 | SYSTEMS AND METHODS FOR IMPROVING CATHETER HOLE ARRAY EFFICIENCY - A peripheral catheter having a catheter tip diffuser for reducing an exit velocity of an infusant within the catheter. Pluralities of diffusion side holes are provided on the tip portion of the catheter. Some examples further include pluralities of annularly arranged, staggered diffusion holes provided on the tip portion of an intravenous catheter to streamline infusant issued from the diffusion holes. An inner surface of each diffusion hole is further angled relative to the inner surface of the catheter lumen such that an infusant within the lumen exits the catheter though the diffusion holes at an angle less than 90°. | 11-19-2009 |
20100324503 | CATHETER HOLE HAVING A FLOW BREAKING FEATURE - A peripheral catheter having a catheter tip diffuser for reducing an exit velocity of an infusant within the catheter. Pluralities of diffusion side holes are provided on the tip portion of the catheter. Some examples further include pluralities of annularly arranged, staggered diffusion holes provided on the tip portion of an intravenous catheter to streamline infusant issued from the diffusion holes. An inner surface of each diffusion hole is further angled relative to the inner surface of the catheter lumen such that an infusant within the lumen exits the catheter though the diffusion holes at an angle less than 90°. | 12-23-2010 |
20110130745 | CATHETER HOLE HAVING AN INCLINED TRAILING EDGE - A catheter having a catheter body with a lumen and a distal lumen opening. The catheter's lumen extends through the catheter body along a longitudinal axis of the catheter body. A hole is formed through a wall of a distal portion of the catheter body. A portion of the proximal surface of the hole is inclined at an acute angle with respect to the longitudinal axis of the catheter body. The acute angle of the proximal hole surface opens proximally with respect to the catheter body. | 06-02-2011 |
20110307117 | SYSTEM AND METHOD FOR HEATING AND INSULATING CONTRAST MEDIA - A system for heating and insulating contrast media is disclosed herein. A thermal insulating cover sized to cover at least a portion of a contrast media container is provided with a heating element. A temperature sensor measures the temperature of the contrast media and communicates this temperature to a temperature controller, which controls the heating element in order to maintain the contrast media near a predetermined temperature. Temperature data is transmitted to a computer system by a data communicator. | 12-15-2011 |

20160073937 | BLOOD SAMPLING SYSTEM FOR IMPROVING DRAW SUCCESS AND REDUCING HEMOLYSIS - An intravenous system can be optimized to improve blood draw success and reduce hemolysis within the blood sample. Multiple optimizations can be made to an intravenous system, such as a peripheral intravenous catheter, to enhance the system's ability to provide blood samples having sufficient quality for many different tests. These optimizations can include features which enable an intravenous system, such as a peripheral intravenous catheter, to continue to perform efficiently when used to obtain blood samples even after the system has been placed within the patient's vasculature for a substantial duration of time. Also, these optimizations can include features for optimizing the fluid path and flow characteristics during blood withdrawal to minimize the amount of hemolysis that may be caused during withdrawal. Further, these optimizations can include features for integrating blood acquisition and dispense capabilities within the system. | 03-17-2016 |
