Abstract
An angled intraosseous access system including a guide block and/or a guide plate is disclosed. The system includes a driver having a body, and including a needle assembly rotatably coupled thereto, the needle assembly defining a needle axis. One of the guide block or the guide plate is configured to engage a skin surface and align the needle assembly axis at a predetermined angle relative to the skin surface to access the medullary cavity at the predetermined angle. Advantageously, the angled needle of the intraosseous access system can mitigate pain during infusion and mitigate backwalling.
