ST-504 safety guide
Why is an open wound a stop-and-ask situation?
Skin integrity changes how a sleeve, pressure, heat, and cleaning question should be handled.
Pause the routine
Do not use pressure to test an irritated area.
Check the care plan
Wound instructions take priority.
Keep equipment clean
Follow the manual and avoid contamination.
An open wound, active skin irritation, or suspected infection changes the question from comfort to suitability. A sleeve can affect contact, pressure, heat, and the ability to observe the skin. A product page cannot decide whether use is safe around a wound.
Follow the wound-care instructions first
Use the current care plan and ask the relevant professional. Do not place the sleeve over a wound because a general article mentions leg comfort. Do not increase pressure to test whether the area tolerates the device.
The safety guide covers non-use and stop signs. The cleaning guide covers device care, but it does not replace wound care instructions.
Stop for skin changes
Stop for pain, burning, bleeding, new redness, unusual warmth, increasing numbness, worsening swelling, or visible device contamination. Keep the device off while the concern is assessed. Record what happened without guessing at an infection or diagnosis.
If the equipment is damaged or contaminated, contact support. Do not open the controller or use a stronger setting to continue the session.
Keep wound care and device care separate
Use clean wound-care materials and the instructions supplied by the treating professional. Do not treat the sleeve as a dressing. Do not apply an unapproved barrier and assume the product instructions still cover the altered setup. If the wound changes, care takes priority over the equipment question.
The instruction for use controls the product boundary. A professional assesses the wound. FDA medical device information provides general context only.
The same boundary applies when the wound is covered by a dressing or when irritation is described as minor. A general page cannot verify the dressing, pressure tolerance, drainage, infection risk, or healing stage. Keep the device off until the care instructions clearly address the situation.
Do not use a product article to judge whether a wound is ready. Ask the care team what contact, pressure, warmth, and cleaning rules apply. If those rules change, update the device plan before using the sleeve again.
The device should remain separate from wound decisions.
