Which non‑expandable medical items can be used?

Non-Expandable Medical Items That Can Be Used

Non-critical medical items that only contact intact skin can be reused after low-level disinfection or cleaning, including blood pressure cuffs, stethoscopes, and similar equipment that does not penetrate tissue or contact mucous membranes. 1

Classification Framework for Medical Device Reuse

The Spaulding classification system provides the definitive framework for determining which medical items can be reused versus those requiring single use:

Critical Items (Cannot Be Reused - Single Use Only)

• Medical devices that enter sterile tissues or vascular spaces
• Examples include injection needles and endoscopic accessories that penetrate mucosal barriers
• These items carry significant infection risk if contaminated and must be sterilized and cannot be reused after single use 1

Semi-Critical Items (Reusable with High-Level Disinfection)

• Devices contacting mucous membranes or damaged skin without penetrating sterile tissue
• Require at least high-level disinfection after use
• Reusable endoscopic accessories (per manufacturer's instructions), endoscopes, and mouthpieces fall into this category 1

Non-Critical Items (Reusable with Low-Level Disinfection)

• Devices that do not ordinarily touch the patient or only contact intact skin
• Can be cleaned using low-level disinfection
• Examples include:
  • Blood pressure cuffs (neonatal, infant, child, and adult sizes) 2
  • Stethoscopes 2
  • Pulse oximeter sensors (when only contacting intact skin) 2
  • Thermometers (with appropriate cleaning) 2

Practical Equipment Examples from Clinical Guidelines

Reusable Equipment in Emergency and Ambulance Settings:

Airway Management (Reusable):

• Laryngoscope handles (with battery replacement) 3
• Magill forceps (adult and pediatric) 2

Monitoring Equipment (Reusable):

• Cardiorespiratory monitors 2
• Defibrillators with replaceable pads 4
• Blood pressure devices and cuffs 4, 5

Orthopedic Equipment (Reusable):

• Splinting materials and commercial devices 4
• Cervical immobilization equipment 2

Single-Use Items That Cannot Be Reused:

Critical Consumables:

• Endotracheal tubes 2, 3
• Suction catheters 2, 3
• IV catheters and needles 3, 2
• Syringes 3
• Nasogastric/orogastric tubes 2, 6
• Urinary catheters 2, 6

Critical Caveats

Manufacturer Instructions Take Precedence: Always follow the manufacturer's instructions for use (IFU) regarding whether a device is intended for single use or reuse 1. The 2024 guidelines explicitly state that reusable endoscopic accessories must be used "according to the manufacturer's instructions for use."

Reprocessing Requirements: For items designated as reusable, proper reprocessing is non-negotiable. The level of disinfection or sterilization must match the Spaulding classification 1.

Developing vs. Developed Countries: While reuse of single-use devices is common in resource-limited settings, this practice carries significant infection risks, particularly for cheap items like needles and syringes, leading to hepatitis B, C, and HIV transmission 7. Reuse of cheap single-use devices should cease in all settings.

Regulated Reprocessing: In developed countries where reuse of expensive single-use devices occurs, it requires ethical and legal considerations, high reprocessing standards, staff training, risk assessment, and validation 7. Well-regulated reprocessing can actually decrease inappropriate reuse.

Storage Considerations

Reusable medical devices require proper storage to maintain their sterility or cleanliness 8. Event-related sterile storage (rather than time-based) is the modern standard, meaning properly packaged sterile items remain sterile until the package is compromised, regardless of time elapsed.
