Model RTubeVOC -End Tidal Air Collector
Portable Collection Devices for the Study of Deep-Lung Volatile Organic Compounds (VOC’s). The RTubeVOC™ End Tidal Air Collector is designed for ease of use by the supervised patient in the clinic, home, school, or hospital. This non-invasive handheld device is fully self-contained and disposable. The RTubeVOC selectivly traps the last bit of exhalate containing primarily alveolar air as the subject fully exhales a single breath into the device. This unique feature allows for easy integration of the RTubeVOC into deep-lung VOC studies and when used in conjunction with Mass Spectrometry allows data to be collected with ease from subjects in nearly any environment. The simplicity and environmental flexibility of this collector offers the potential for rapid development of clinical diagnostics utilizing Volatile Organic Compounds derived from the deep lung and alveoli.
- Evolutionary design has been proven safe and reliable in over 200,000 collections
- Sealable collection tube allows short-term specimen storage for transport
- Easily interfaces with any mass spectrometer using our Universal Needle Interface
- Optimized for use with the upcoming Respiratory Research Portable Mass Spectrometer
- Custom valve/piston traps End Tidal Air and allows the controlled, contamination-free discharge of the exhalate into the analyzer
- Disposable design ensures a clean device ready for use at any time with no risk of infectious disease transmission between patients
- Simple handheld device is easy to use by just about anyone
The video outlines the procedures for use. A couple of points to consider:
- In an adult, End Tidal Air is typically considered to be the last bit of exhalate trapped after a single continuous exhalation lasting 6 seconds or more
- In a child, End Tidal Air is typically considered to be the last bit of exhalate trapped after a single continuous exhalation lasting 3 seconds or more
- Continuous exhalation is required for the device to work correctly. Inhaling through the device at the end of the exhalation may contaminate the sample with ambient air
The RTube is CE Marked under the Medical Device Directive (93/42/EEC) and the In Vitro Diagnostic Directive (98/79 EC).
RTube is registered with the United States Food and Drug Administration as a Class I device for the collection of expired gas. The RTube can be incorporated into most clinical investigations in the United States.
This of course does not mean it is exempt from individual entity’s Institutional Review Board or Human Investigation Committee. For research protocols, each individual Institutional Review Board/ Human Investigation Committee may wish to make its own determination as to the non-significant risk nature of the device, especially if the device is modified or incorporated into other equipment such as ventilator circuits.
