Abstract: Devices and methods for an autovance intraosseous device. The autovance intraosseous device can include a trigger activated system or pressure activated system that causes a needle to advance distally for a predetermined distance. The predetermined distance ensures a needle tip extends through the bone cortex, to access the medullary cavity, without penetrating a far wall of the medullary cavity. The advancement can be driven by a spring based system or an electric motor.

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.

Abstract: Disclosed herein are intraosseous access devices having various operating mechanisms, as well as methods of the intraosseous access devices. For example, an intraosseous access device includes, in some embodiments, a constant-torque spring assembly, a drive shaft, an intraosseous needle, and an interlock mechanism. The constant-torque spring assembly is disposed in a housing, and the drive shaft extends from the housing. The drive shaft is coupled to the constant-torque spring assembly. The intraosseous needle is coupled to the drive shaft. The intraosseous needle is configured for drilling through bone and providing intraosseous access to a medullary cavity of a patient. The interlock mechanism is configured to prevent rotation of the intraosseous needle and the drilling therewith until the interlock mechanism is disengaged.

Abstract: A pole system comprising a continuous elongated frame forming both structural and functional geometries relating to the handle and shaft portions. The continuous elongated frame may include an internal cavity and a variable wall thickness along the lengthwise dimension. The handle portion of the continuous elongated frame includes a cap region, grip region, and a retention region. The independent regions of the handle portion may include substantially different cross sectional shapes to facilitate the corresponding functional characteristics. For example, the grip region may include an ergonomic tapered oval cross sectional shape to facilitate optimal engagement with a user's hand. The shaft portion of the continuous elongated frame is disposed between the handle portion and the bottom end of the continuous elongated frame. The tip is either integrated as a portion of the continuous elongated frame or translatably coupled via a lower pole member.

Abstract: One embodiment relates to a snow shovel system with an extended and collapsed state. The system includes a blade member, handle, lower shaft member, and upper shaft member. One end of the lower shaft member is coupled to the blade member and the other is slidably coupled with the upper shaft member. A first end of the upper shaft member is coupled to a handle and the second end is slidably coupled with the lower shaft member. The slidable coupling between the lower and upper shaft members includes an extended state and a collapsed state in which the handle is separated from the blade member a greater distance in the extended state. The collapsed state includes translating a portion of the lower shaft member beyond the first end of the upper shaft member.

Abstract: One embodiment of the present invention relates to a dual mode snow shovel system including a hoe mode and a shovel mode. The system includes a blade member, shaft member, and handle. The shaft member may include an upper and lower shaft member slidably intercoupled to facilitate extended and collapsed configurations. A first end of the shaft member is releasably coupled to the blade member in a radially reversible orientation to facilitate either the shovel mode or the hoe mode. The shaft member includes a curvature disposed in proximity to the first end, and the blade member includes a corresponding curvature. The shovel mode includes a substantially parallel orientation of the blade member and the substantially straight lengthwise orientation of the shaft member. The hoe mode includes a substantially orthogonal orientation of the blade member and the substantially straight lengthwise orientation of the shaft member.
