Abstract
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.
