Abstract
An intraosseous device may include a chamber portion having a proximal end and a distal end, wherein the proximal end includes a base, a tensile puller configured to extend through the chamber portion and slidingly engage the base, the tensile puller comprising a proximal end and a distal end, an actuator on the proximal end of the tensile puller, and a connector on the distal end of the tensile puller adapted to engage a needle.
Claims20
An intraosseous device, comprising:
- a chamber portion having a proximal end and a distal end, wherein the proximal end includes a base comprising a receiving component and a removable component;
- a tensile puller extending through the chamber portion and slidingly engaging the receiving component, the tensile puller comprising a continuous member extending from a proximal end to a distal end;
- a laterally extending handle configured for pulling the tensile puller and a needle from a bone, the laterally extending handle being arranged on the proximal end of the tensile puller and defining a proximal most end of the intraosseous device;
- a connector on the distal end of the tensile puller adapted to engage the needle;
- and
- a lock arranged on the chamber portion and configured to directly engage with the tensile puller.

A method for extracting an intraosseous needle from a patient comprising:
- providing a medical device comprising a chamber, a tensile puller, a laterally extending handle, a connector, and a lock configured to directly engage the tensile puller, wherein the chamber comprises a base with a receiving component and a removable component;
- coupling the needle to the connector on a distal end of the tensile puller;
- applying a force to the chamber towards a distal end of the chamber such that the distal end of the chamber contacts a patient body;
- and
- applying an opposing force to the laterally extending handle on a proximal end of the tensile puller, the opposing force effectively altering the tensile puller from a deployed position to a retracted position by sliding relative to the receiving component.
