Patent number: 12502514Abstract: A vascular access device adapter allowing for interchangeable connections between separate components of a larger extravascular system while minimizing exposure to non-sterile environments in point-of-care testing and analysis is provided. The vascular access device adapter includes a body having a self-healing puncturable septum secured by an end cap by which hollow small gauge needles may extract or deposit fluid. The adapter device further includes an end cap enclosing the septum, the end cap having ribs which removably secure the adapter to the inner housing of a sample collection device.Type: GrantFiled: August 26, 2020Date of Patent: December 23, 2025Assignee: Becton, Dickinson and CompanyInventors: Bo Yan, Yueqiang Xue, Xiwei Chen, Jonathan Karl Burkholz

Patent number: 12207926Abstract: A vascular access system which may be configured for blood draw may include a housing, which may include a distal end, a proximal end, and a slot disposed between the distal end and the proximal end. The slot may include a notch. The vascular access system may include a cannula hub, which may be disposed within the housing and movable with respect to the slot. The cannula hub may include a tab extending through the slot. The vascular access system may include a cannula extending distally from the cannula hub. In response to the tab being disposed within the notch, a distal tip of the cannula may be disposed within the housing. In response to advancing the tab along the slot to a distal end of the slot, the distal tip of the cannula is disposed distal to the distal end of the housing.Type: GrantFiled: April 24, 2023Date of Patent: January 28, 2025Assignee: Becton, Dickinson and CompanyInventors: Bo Yan, Xiwei Chen, Tao Jiang, Olivia Hu

Publication number: 20230397859Abstract: A blood draw system may include a catheter adapter connector in fluid communication with a catheter adapter, and a blood draw device in selective fluid communication with the catheter adapter connector. A first valve may be utilized to selectively permit fluid communication between the blood draw device and the catheter adapter connector. A flush device may also be in selective fluid communication with the catheter adapter connector to flush the catheter adapter after a blood draw procedure. A second valve may be utilized to selectively permit fluid communication between the flush device and the catheter adapter connector.Type: ApplicationFiled: November 1, 2021Publication date: December 14, 2023Inventors: Bo Yan, Xiwei Chen, Simon Liu, Yueqiang Xue, Yijie Wu, Jithendra Kumar, Tao Jiang

Publication number: 20230301567Abstract: An insert for a catheter system may include a distal end, a proximal end, and a middle portion disposed between the distal end and the proximal end. The distal end of the insert may include a male port, and the proximal end of the insert may include a female port opposite the male port. The insert may be configured to extend through an adapter and/or a needleless connector of a catheter system to reduce exposure of the adapter and/or the needleless connector to blood, which may flow through a lumen of the insert. The lumen of the insert may extend through the male port, the middle portion, and the female port.Type: ApplicationFiled: October 19, 2021Publication date: September 28, 2023Inventors: Xiwei Chen, Bo Yan

Publication number: 20230233813Abstract: An intravenous (IV) catheter assembly may include a catheter adapter and a catheter extending from the distal end of the catheter adapter. The intravenous (IV) catheter assembly may include an introducer needle. The elongated shaft may include a flashback notch, and the flashback notch may include a distal end and a proximal end. The flashback notch may include a smooth tapered edge extending from the distal end in a direction that increases a depth of the flashback notch. The smooth tapered edge may extend along at least half of an entire length of the flashback notch between the distal end and the proximal end.Type: ApplicationFiled: December 5, 2022Publication date: July 27, 2023Inventors: Xiwei Chen, Linda Kunardi, Xue Guang John Ong, Bo Yan, Gary Liu
