Publication number: 20230256205Abstract: An introducer needle may include a proximal end, a distal tip, and a needle lumen extending therebetween. The introducer needle may include a wall defining the needle lumen, a first notch formed through the wall, and a second notch formed through the wall. A catheter system may include a catheter adapter, a catheter extending distally from the distal end of the catheter adapter, a flash chamber coupled to the introducer needle, and the introducer needle, which may extend through the catheter. The first and second notches and the flash chamber may facilitate pressure-driven blood flow into the catheter for improved flashback and detection of transfixation when the catheter is primed prior to insertion into vasculature of a patient or otherwise.Type: ApplicationFiled: April 24, 2023Publication date: August 17, 2023Inventors: Yiping Ma, Bryan G. Davis, Weston F. Harding, Jonathan Karl Burkholz

Patent number: 10182753Abstract: A blood sampling device useful for collecting a blood sample from a separate vascular access device is described herein. The blood sampling device includes a body shaped and sized for partial insertion into a separate vascular access device. The body includes a reservoir defined within the body, which has an internal volume sufficient to contain enough blood for use in a diagnostic blood test. The body also includes a gas permeable vent disposed on the body, in which the gas permeable vent is in gaseous communication with the reservoir. When connected to a separate vascular access device the blood sampling device collects a blood sample as blood flows into the reservoir from the separate vascular access device and as gases pass out the reservoir via the gas permeable vent.Type: GrantFiled: October 26, 2015Date of Patent: January 22, 2019Assignee: Becton, Dickinson and CompanyInventors: Bryan G. Davis, Jonathan Karl Burkholz, Minh Quang Hoang, Yiping Ma

Patent number: 9750922Abstract: A handheld antiseptic dispensing applicator device having a reservoir for storing an antiseptic agent, the reservoir being coupled to an applicator pad, and a defeatable membrane or barrier being interposed between the reservoir and the applicator pad. Embodiments of the device comprise a squeezable reservoir, wherein the internal hydraulic pressure of the squeezable reservoir is increased via user applied forces to thereby defeat the membrane releasing the antiseptic agent contained therein which is then absorbed by the applicator pad. The defeatable barrier or membrane is also removable or may be defeated in connection with other mechanisms according to various embodiments.Type: GrantFiled: February 20, 2014Date of Patent: September 5, 2017Assignee: Becton, Dickinson and CompanyInventors: Minh Quang Hoang, Huibin Liu, Jonathan Karl Burkholz, Bryan G.

Patent number: 9549701Abstract: A vent plug is disclosed that includes a body having a distal end, a proximal end, and a lumen extending through the distal and proximal ends. A membrane is disposed across the lumen, the membrane being hydrophobic and air permeable. A fluid chamber is formed within the lumen distal the membrane. A distal lumen opening being shaped and sized to retain blood within the lumen until the internal pressure of the lumen increases in response the a finger pressing against a proximal lumen opening.Type: GrantFiled: July 18, 2011Date of Patent: January 24, 2017Assignee: Becton, Dickinson and CompanyInventors: Bart D.

Publication number: 20160213862Abstract: An IV set can include an air stop membrane and one or more additional components including a zero dead space luer access device, a vent cap, a bubble removal component, an antimicrobial coating, insert, or filter, or a precision flow controller. An air stop membrane can be used within the IV set to maintain a fluid column within the IV set downstream of the membrane even after a fluid bag has emptied. By maintaining a fluid column downstream of the membrane, air is prevented from entering into the tubing that couples the IV set to a vascular access device. For this reason, once a fluid bag has emptied, a new fluid bag can be coupled to the IV set without needing to re-prime the IV set. Therefore, a clinician need not be present as a fluid bag is emptying to ensure that air does not enter the tubing.Type: ApplicationFiled: January 25, 2016Publication date: July 28, 2016Inventors: Weston O. Whitaker, Shaun Staley, Bryan G. Davis

Patent number: 9283321Abstract: A system for recording the wasting of fluids includes a waste disposal unit and a sensor system, having a sensor. The sensor can have one or more sensor elements in fluid communication with a fluid as it is wasted from a container into the waste disposal unit. The sensor system is configured to identify one or more drugs within the fluid and record the identity of the one or more drugs in a computer-readable medium electrically coupled to the sensor system.Type: GrantFiled: March 1, 2012Date of Patent: March 15, 2016Assignee: Becton, Dickinson and CompanyInventors: Elizabeth Nelson, Bart D.
