Area of Science:

  • Anesthesiology
  • Medical Device Engineering
  • Materials Science

Context:

  • Laryngeal mask airway (LMA) use is common in anesthesia.
  • Protecting the LMA from patient biting is crucial for device integrity and patient safety.
  • Existing bite blocks can be costly or have limitations.

Purpose:

  • To develop and evaluate a novel, low-cost bite block for LMAs using repurposed anesthesia equipment.
  • To assess the physical properties, specifically biting resistance and laryngeal mask fit, of the new bite block.
  • To determine the clinical utility and safety of the novel bite block in anesthetic procedures.

Summary:

  • A new bite block was fabricated from a used anesthesia machine connector (ACOMA medical industry CO., LTD.).
  • The connector was modified by lengthwise cutting to create a functional bite block for laryngeal mask insertion.
  • Experimental testing confirmed the bite block's adequate strength to withstand patient biting and its suitable fitness for laryngeal mask application.

Impact:

  • Provides a cost-effective alternative for airway management devices.
  • Enhances patient safety by preventing laryngeal mask damage during anesthesia.
  • Demonstrates the potential for repurposing medical equipment to create innovative solutions.
