Abstract
Constant-torque intraosseous access devices and methods thereof are disclosed. 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 such an intraosseous access device can include inserting a distal end of the intraosseous needle through skin at an insertion site of a patient; applying force to bone at the insertion site with the distal end of the intraosseous needle, which starts winding a metal ribbon of the constant-torque spring assembly from an output spool onto a storage spool, thereby starting rotation of the intraosseous needle; and drilling through the bone until the intraosseous needle enters a medullary cavity of the patient, thereby achieving intraosseous access with the intraosseous access device.
