Publication number: 20150073392Abstract: An intravenous infusion system that shows infusion flow rate, volume of medication infused, and alarming during malfunction. User intervention to adjust flow rates deviation is possible, using the data already stored in the system prior to the onset of making the adjustment.

Patent number: 8888758Abstract: A medical connector for minimizing leakage of fluids during connection and disconnection is described. The medical connector includes a body having an inlet port, at least one outlet port adjacent to a male luer portion of the body, and a fluid path between the inlet port and the at least one outlet ports. A retractable seal adjacent to the male luer portion of the body and blocks the outlet ports of the body when the male luer portion of the medical connect is in a disconnected state. The retractable seal is positioned on the body such that it is moved away from the outlet ports upon insertion of the male luer portion of the medical connector into a medical access device thereby unblocking the outlet ports and creating a fluid path through the medical connector.Type: GrantFiled: September 5, 2008Date of Patent: November 18, 2014Assignee: Carefusion 303, Inc.Inventors: George Michel Mansour, Tim L. Truitt, Matthew P. Fried

Patent number: 8882744Abstract: An outflow conduit for a cardiac assist pump has a connector at one end comprised of a main sleeve configured to mate with a pump outlet port. A plurality of prongs extend from the sleeve. Each prong has a distal end with a claw and is bendable so that its respective claw expands over a lip and enters the groove of the outlet port. A lock nut is movable between a retracted position and a locking position. In the retracted position, a soft interconnect is obtained. In the locking position, the claws are prevented from escaping over the lip and a hard interconnect is obtained.Type: GrantFiled: February 27, 2012Date of Patent: November 11, 2014Assignee: Thoratec CorporationInventors: Christopher P. Dormanen, Sunil K. Dasara, Takeshi Tsubouchi

Patent number: 8876798Abstract: A clam shell shaped adapter for retaining a catheter to establish a fluid path between the catheter and a fluid device or line has first and second shells integrally connected by a living hinge. The first shell has a luer end and a catheter end. A flexible tubing at an inner surface of the first shell connects the luer end to the catheter end. The catheter is inserted through the catheter end to extend along the flexible tubing. A retainer structure is provided at an inner surface of the second shell so that when the first and second shells close upon each other, the retainer structure presses against the flexible tubing to fixedly retain the catheter in a fluidly sealing manner. Respective latch mechanisms provided at the shells lockingly couple the first and second shells to each other.Type: GrantFiled: February 23, 2010Date of Patent: November 4, 2014Assignee: Smiths Medical ASD, Inc.Inventors: Geoff Clark, Christian Schlerf

Patent number: 8870849Abstract: A catheter hub includes a distal assembly including a distal hub member adapted to be fixedly attached to an outer catheter and a proximal assembly including a proximal hub member adapted to be fixedly attached to an inner catheter disposed through the outer catheter. An elongate member connects the proximal and distal assemblies such that the proximal and distal assemblies can translate longitudinally relative to one another.Type: GrantFiled: April 8, 2011Date of Patent: October 28, 2014Assignee: BiO2 Medical, Inc.Inventors: Jeffrey N. Steinmetz, Joseph H. Taber

Patent number: 8870238Abstract: A female connector for medical infusion systems has a main body that has two curved wings that extend from the outer circumferential surface of the body. The respective front ends of the wings are joined integrally to a substantially circumferential partition that also extends circumferentially from the outer circumferential surface of the fitting. The connector of the fitting has a non-conventional configuration with at least two protuberances offset at an angle. The non-conventional configuration of the connector allows the fitting to only mate with a counterpart connector that has a complementary non-conventional configuration.Type: GrantFiled: June 14, 2012Date of Patent: October 28, 2014Assignee: Smiths Medical ASD, Inc.Inventors: Renee Robert, Chad Amborn, Geoff Clark

Patent number: 8870850Abstract: A valve for selectively permitting a fluid flow between first and second medical implements is disclosed. The valve has a housing with an interface suitable for receiving a connector portion of a first medical device such as a catheter, and a seal made of a flexible material. The seal has a first end in fluid communication with the interface, a second end suitable for receiving the second medical device, and at least one slit in fluid communication with the first end and the second end. The slit defines a restricted fluid flow path and a relatively small interior volume when in an undisturbed state, defines an expanded fluid flow path and a larger interior volume upon the introduction of the second medical instrument into the slit, and retracts to define a restricted flow path and a small interior volume upon the withdrawal of the second medical device from the seal.Type: GrantFiled: May 20, 2013Date of Patent: October 28, 2014Assignee: ICU Medical, Inc.Inventor: Thomas F. Fangrow, Jr.
