Summary
This study introduces a novel, cost-effective bite block for laryngeal masks, repurposed from anesthesia machine connectors. The new device demonstrates sufficient strength and fitness for safe clinical use during anesthesia.
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.
