Home healthcare equipment: what the ST-504 page can establish
The ST-504 instruction for use lists home healthcare and professional healthcare environments in its EMC section. That wording describes the environment. It does not make the device a substitute for a clinician, prescribed equipment, or a personal treatment plan.
Start with the operating environment
Before use, check the controller, sleeve, tubing, cable, and power source. Use the device while awake and seated. Keep the controller within reach. Follow the current instruction for mode, pressure, heating, vibration, session time, and cleaning.
The environment also matters. Keep the equipment dry and away from MRI, HF surgical equipment, microwave ovens, strong radio-frequency sources, and other equipment that may interfere with operation. Review the EMC guidance for medical devices when the device will be used near electronic equipment.
What home use does not answer
Home healthcare equipment can describe a routine and its operating boundaries. It cannot determine whether compression is suitable after surgery, with unexplained swelling, reduced sensation, a circulation diagnosis, or a new symptom. Use the safety and contraindications guide and ask a qualified clinician when those conditions apply.
A practical support path
Use the ST-504 complete guide for product scope and controls. Use the troubleshooting guide for device behavior that does not match the manual. Contact support when equipment is damaged or continues to operate unexpectedly.
Plain-language check
Keep the room dry. Keep the unit in reach. Stay awake. Sit still. Check the sleeve and tube. Stop if the fit is not right. Ask a care pro if the use is not clear.
