SAM IO Driver for Intraosseous Access

Key Specifications

Product Overview

Intraosseous access is a life-saving technique when peripheral IV access cannot be established in a critically injured patient. The SAM IO Driver from SAM Medical offers a uniquely reliable approach: a passive ratcheting mechanical system that spins the needle clockwise only when resistance is encountered, giving the clinician precise tactile feedback during cortical bone penetration. This feedback-driven insertion mechanism reduces the risk of over-penetration and provides a clear, tangible endpoint when the IO needle crosses the cortex into the medullary space.

Unlike battery-powered IO drivers such as the EZ-IO, the SAM IO Driver requires no batteries, eliminating a critical failure mode in austere and extreme-temperature environments. The polycarbonate housing is tested to MIL-STD-810G standards for shock, vibration, and environmental exposure — and the driver itself is multi-use: it can be cleaned between patients and has been tested to hundreds of actuations, making it suitable for both training and sustained operational use. The lightweight 2.5-oz driver is significantly lighter than battery-powered alternatives, contributing to a lower overall IO kit weight.

Catheter placement is achieved by continuously actuating (repeatedly compressing) the trigger assembly while gently guiding the needle assembly into position. The ratcheting mechanism ensures the needle rotates only clockwise under resistance — it does not spin freely — which translates operator force into controlled, incremental cortical penetration. Once the catheter is properly seated, the stylet is removed and the standard Luer-lock port is connected via the SAM IO Adaptor (MEDTAC1061) to begin aspiration, flushing, and treatment.

IO Placement — Step by Step

1. Select appropriate needle size: 15 mm (pediatric/thin), 25 mm (standard adult), 45 mm (obese/proximal humerus).
2. Identify and prepare the IO site (proximal tibia is most common; proximal humerus for adults).
3. Insert the SAM IO Needle into the driver and position the needle tip at the insertion site.
4. Continuously actuate the trigger while applying gentle downward pressure — the ratchet mechanism creates controlled clockwise rotation.
5. Feel for the tactile change in resistance as the needle enters the medullary space (a distinct "give").
6. Remove the stylet. Attach the SAM IO Adaptor and an extension set.
7. Aspirate to verify placement, flush with saline, and begin treatment.
8. Secure catheter with the SAM IO Stabilizer (MEDTAC1059) to prevent dislodgement.
