Abstract
An intraosseous access system includes a driver, a needle, and an obturator positioned in the needle to prevent entry of bodily tissues into the lumen. The driver includes control logic configured to modify operation of the driver upon an indication that a change in modality is detected. The obturator includes a sensor such as an electrical impedance sensor. The electrical impedance sensor can include a passive RFID chip configured to activate when the change in modality is detected.
Claims10
An intraosseous access system, comprising:
- a driver including a control logic configured to modify operation upon an indication that a change in modality is detected;
- a needle defining a lumen and including a beveled tip defining a facet extending at an angle relative to a longitudinal axis of the needle, an aperture disposed in the facet communicating with the lumen of the needle;
- and
- an obturator positioned in the lumen of the needle, a planar distal surface of the obturator aligned with the aperture of the needle and angled to align with the facet to prevent entry of bodily tissues into the lumen of the needle, a distal-most tip of the needle disposed distally of a distal-most tip of the obturator when the planar distal surface is aligned with the facet, the obturator comprising an electrical impedance sensor including a passive RFID chip configured to activate when the change in modality is detected.
