Typical breathing circuits use a wide range of componentry and numerous design options are available, including:
- Facemasks
Injection molded flexible PVC - Oxygen hoods
Flexible PVC film - Nasal canula
Injection molded PVC or Cellene® TPE
- Smoothbore tubing
Coextruded rigid and flexible PVC - Manual inflation bag
Molded Cellene® TPE - Medical gas hose
Antistatic flexible PVC tube
Supraglottic devices, such as the laryngeal mask airway (LMA), are primarily used in operating theater where a patient is under general anesthetic.
Typical components used in a LMA include:
- Multi-lumen airway tubing
Injection molded or Extruded Flexible PVC or Cellene® TPE - Inflation line tubing
Flexible PVC tube - Inflation cuff
Blow molded Flexible PVC or Cellene® TPE with a frosted surface finish
- Back plate
injection molded Flexible PVC - Inflation valve
Injection molded Rigid PVC - Pilot balloon
Molded Flexible PVC with heavily frosted surface finish
Endotracheal tubes come in a range of designs, including oral or nasal, cuffed or uncuffed, preformed, reinforced tubes, and with a double-lumen airway endobronchial intubation.
Most common device components used for a cuffed endotracheal tube include:
- Multi-lumen airway tubing
Extruded Flexible PVC - Inflation line tubing
Flexible PVC tube - Inflation cuff
Blow molded Flexible PVC with a frosted surface finish
- Inflation valve
Injection molded Rigid PVC - Pilot balloon
Molded Flexible PVC with heavily frosted surface finish - Radiopaque stripe tubing
Flexible PVC filled with high level of BaSO4 (or other radiopaque material)
Tracheostomy tubes are preformed, can be reinforced – and can come either cuffed or uncuffed.
Typical components used for a cuffed tracheostomy tube include:
- Multi-lumen airway tubing
Extruded Flexible PVC - Inflation line tubing
Flexible PVC tube - Inflation cuff
Blow molded Flexible PVC with a frosted surface finish
- Inflation valve
Injection molded Rigid PVC - Pilot balloon
Molded Flexible PVC with heavily frosted surface finish
Both tubes can be designed and fitted with a vacuum breaker to control the level of suction being applied and limit the risk of trauma to the patient.
Typical components used for these tube types are:
- Flexible Airway tubing
Extruded Flexible PVC with “satin finish” - Funnel Connector
Injection molded PVC (colour coded for sizing purposes) - Vacuum control valve
Injection molded Rigid PVC (Colour coded for sizing)
- Bubble Airway Tubing
Extruded semi-Rigid PVC
