  1. Tubing Adapter for Infants and Children Advisor: Professor Chris Brace Client: Christopher Green Team Members: Claire Wardrop-Communicator Beom Kang Huh-BSAC TongKeun Lee-BWIG Kimberli Carlson-Leader

  2. Overview • Angled Adapter • Parallel Adapter • Final Design Selection Matrices • Future Work • Problem Statement • Motivation and Background • Client Requirements • Swivel Adapter

  3. Problem Statement • Tubing adapter used on children and infants is same for adults • Current adapter takes up most of chest • This area accessed to monitor breathing, heart, and abdomen • Difficult to move because of angled tubes • New adapter needs to be sized for smaller patients • Needs to allow for easy access to chest for patient monitoring • Reduce dead space

  4. Motivation and Background • Reduce size to proportional size with child and infant size • Adapter is meant to only occupy upper chest only • Current adapter occupies most of chest and abdomen of infants and child • Allow for easy access for monitoring patient lungs, heart, and abdomen

  5. Client Requirements • Minimal size and weight (less than 0.5 kg) • Pressure sensor and temperature gauge opening • Adapter must not collapse • Material must be patient safe • Standardized 15mm openings • Cost effective

  6. Swivel Adapter • Single unit • Combines elbow piece and adapter • Swivels to allow adapter to rest on patient’s chest • Angled tubing connection • Minimizes dead space Pressure Sensor Temperature Gauge

  7. Angled Adapter Pressure Sensor • Temperature gauge separate • Flexible material • Expiratory connects to adaptor • Angled design spreads tubing • Overall shorter Temperature Gauge

  8. Parallel Adapter • Single Unit Adapter • Inspiratory and expiratory tube is connected directly to adapter • Minimizes area tubing takes up on patient’s chest Temperature Gauge Opening Pressure Sensor

  9. Final Design Selection

  10. Material Selection

  11. Final Design • Parallel Adapter • Allows easy movement • Minimal interference with monitoring patient • Cost effective • Polypropylene will be used to when adapter is manufactured

  12. Future Work • Run test to find optimal distance between pressure sensor and temperature gauge • Build prototype
