Tube Fixation Strap

The Body Surface Conduit Fixing Device - Type G is a Class I medical device specifically designed for the mechanical fixation of medical catheters, tubing, and drainage lines to the patient's body surface . Operating on a strap-based mechanism, Type G devices utilize an adjustable nylon adhesive strap (often hook-and-loop/Velcro material) that wraps around the conduit rather than relying on broad adhesive patches adhered directly to the skin for the primary hold .

For the clinician and wound care nurse, Type G provides a valuable alternative to adhesive-based fixation for patients with fragile, damaged, or sensitive skin. The nylon adhesive strap is loosened, moved to the appropriate position along the catheter line, placed around the tube, and then tightened to the correct tension . This mechanical hold minimizes direct skin contact with adhesives, reducing the risk of medical adhesive-related skin injury (MARSI) while still providing a secure grip on the conduit.

For the patient, especially those with a history of dermatitis, fragile skin, or those requiring long-term catheterization, Type G offers a comfortable, breathable alternative. The use of breathable, comfortable non-woven fabric helps prevent edge warping and moisture accumulation . The strap can be periodically loosened, the skin inspected, and the device retightened without requiring a complete dressing change, preserving supplies and reducing patient discomfort. Type G devices are suitable for securing feeding tubes, drainage catheters, and central lines where a traditional adhesive securement may be contraindicated or where frequent line adjustments are necessary.
