Publication number: 20230414251Abstract: An intraosseous access device can include a constant-torque spring assembly disposed in a housing, a drive shaft extending from the housing, and an intraosseous needle coupled to the drive shaft configured to provide intraosseous access to a medullary cavity of a patient. A method of using an intraosseous access device can include inserting a distal end of the intraosseous needle through skin at an insertion site of a patient and applying a contacting force to a bone beneath the insertion site with the distal end of the intraosseous needle. The contacting force can initiate a winding of a metal ribbon of the constant-torque spring assembly from an output spool onto a storage spool, thereby initiating drilling rotation of the intraosseous needle. The method can further include drilling through the bone until the intraosseous needle enters a medullary cavity of the patient.Type: ApplicationFiled: September 11, 2023Publication date: December 28, 2023Inventors: Daniel Pett, Daniel B. Blanchard, Eric W. Lindekugel, Joe Spataro, Ralph Sonderegger

Patent number: 11260173Abstract: A needle assembly including a needle having a sharpened end and an opposing end and a needle tip shield for shielding the needle. The needle tip shield includes a needle shield connectable to a base and a needle hub fixedly connected to the opposing end. The needle shield and needle hub displace relative to each other from a first state, in which the sharpened end of the needle is exposed outside the needle shield, to a second state, in which the sharpened end of the needle is shielded by the needle shield. An actuation button is movably connected to the needle hub to maintain the needle shield and needle hub in a releasable locked state in a first button position relative to the needle hub and to permit the needle shield and needle hub to displace relative to each other in a second button position relative to the needle hub.Type: GrantFiled: September 14, 2017Date of Patent: March 1, 2022Assignee: Becton, Dickinson and CompanyInventor: Ralph Sonderegger
