Q: Does the use of Q235 steel in the medical industry need to comply with relevant national standards?
A: Yes, it does. The basic standard must comply with "Carbon Structural Steel" (GB/T 700), and it must also meet the stress requirements of structural components in the overall design specifications of medical equipment/facilities (such as the GB 9706 series of medical electrical equipment standards).
Q: Why can't Q235 steel be used in core contact parts of medical devices?
A: It lacks corrosion resistance, is prone to rust, and rust can contaminate human tissue, blood, and medications; it lacks antibacterial properties, and bacteria easily grow on its surface; the material itself is not biocompatible, and contact with the human body can cause irritation or infection.
Q: In which specific parts of medical beds is Q235 steel used?
A: In non-contact parts of medical beds, such as the main frame, bed frame beams, bed leg supports, and side rail frames, formed by welding/bending, bearing the weight of the bed and the human body.
Q: Can Q235 steel be used in the structural fabrication of operating tables?
A: It can be used in non-adjustable, non-contact parts such as the bottom support base of the operating table and the main frame of the lifting bracket. Core adjustment and surgical contact areas must be made of stainless steel.
Q: What are the applications of Q235 in medical trolleys?
A: Metal frames, handrail skeletons, and wheel frame connections of treatment trolleys, nursing trolleys, and waste trolleys, after surface coating treatment.
