Patent number: 11413432Abstract: A self-slitting open lumen cannula may be used with catheter adapters to reduce manufacturing complexity and costs, as well as improve the safety of the catheter adapters against fluid leakage. The open lumen cannula may also include one or more notches to facilitate flashback visualization. The catheter adapters may further include a catheter adapter body formed of a compliant material that houses one or more compression resistant septa with at least one lumen formed by the proximal end of the needle during a self-slitting process as the catheter adapter is assembled. The compression resistant septum may also be coupled to a compression cap that imparts a radial compression force on the one or more compression resistant septa such that the at least one lumen narrows and seals when the cannula is removed.Type: GrantFiled: October 1, 2019Date of Patent: August 16, 2022Assignee: Beeton, Dickinson and CompanyInventors: Daniel Kirk Hyer, Christopher Maul, Eric Davis, Bin Wang, Carl Ellis, Corey Christensen, Jonathan Karl Burkholz, Bart D.

Publication number: 20200294071Abstract: In one implementation, a method for determining user intents for a website includes accessing, by an analytics system, site search data for the website. The website can include a plurality of webpages and the site search data can include (i) site search queries for the website and (ii) site search user behavior that identifies particular webpages from among search results for the site search queries. The method can further include determining query-page scores for each pair of the site search queries and the plurality of webpages based on the site search data. The method can additionally include generating combined scores for the site search queries based on the query-page scores. The method can also include identifying groupings of the site search queries based on the combined scores, determining user intents for the website based on the groupings of the site search queries, and outputting the determined user intents.Type: ApplicationFiled: March 12, 2020Publication date: September 17, 2020Inventors: Corey Christensen, Niels Ebbe Ebbesen

Patent number: 9675752Abstract: A drug delivery device, including a body (104, 116) having a reservoir (160) disposed therein for containing a medicament and an injection needle (152) for penetrating the skin of a patient, the needle (152) providing a path for the medicament between the reservoir (160) and the patient. The device also includes a rotor (580) rotatably disposed in the body (104, 116) for activating the device upon rotation of the rotor (580), a needle cover (112) for covering the injection needle, and a needle cover clip (560) disposed on the needle cover (112) to rotate from a first position preventing rotor rotation to a second position permitting rotor rotation.Type: GrantFiled: December 22, 2014Date of Patent: June 13, 2017Assignee: Becton, Dickinson and CompanyInventor: Corey Christensen

Patent number: 9677390Abstract: A reciprocating pump drive assembly for driving a reciprocation of a polish rod relative to a well casing includes a support frame which supports a pair of hydraulic actuators such that the cylinder portions thereof are fixed relative to the well casing. A mounting frame is supported at a top end thereof on the top ends of the piston portions of the hydraulic actuators so as to extend downwardly to a polish rod mounting bracket at the bottom end of the mounting frame. The top end of the polish rod is thus supported by the mounting frame so as to be suspended below the top end of the hydraulic actuators for improved access during servicing and for greater overall lateral stability of the drive assembly.Type: GrantFiled: December 4, 2014Date of Patent: June 13, 2017Assignee: AMIK OILFIELD EQUIPMENT AND RENTALS LTD.Inventor: Corey Christensen

Patent number: 9108021Abstract: A septum is disclosed that can be utilized in a catheter assembly to selectively seal an opening in the catheter assembly. The septum has a tube portion and a plug portion. The plug portion has a slit extending through it. The septum can transition from a non-collapsed state to a collapsed state. When the septum is in a non-collapsed state, the plug portion is offset from the tube portion such that some of the length of the slit extends outward from the distal end of the tube portion. When the septum transitions to the collapsed state, the plug portion is moved inward into the internal cavity such that some of the length of the slit may or may not extend outward from the distal end of the tube portion.Type: GrantFiled: February 22, 2012Date of Patent: August 18, 2015Assignee: Becton, Dickinson and CompanyInventors: Daniel Kirk Hyer, Corey Christensen, Carl Ellis
