Device for Long Term and Reusable Breath Samples

Tech ID: rez000966



In recent years, the development of biorepositories to store various biologic samples has been fundamental in revolutionary advances of drug discoveries, microbiome research, genomics and personalized medicine. Globally, a number of biobanks are available and provide researchers, clinicians and patients with organic samples and associated clinical data. Current biorepositories store biologic samples that include stool, blood, plasma, tissue, urine, hollow organ aspirates and sperm.


Currently, no apparatus exists for bio-reposition of breath samples for long-term storage and subsequent sampling of the breath gas. A system that could store breath gases from research studies long term and allow researchers to extract samples of the gases at future dates could be quite beneficial. A biobank that can store breath samples with their corresponding clinical, radiologic and diagnostic laboratory data will be an invaluable asset.


There are currently multiple breath test bag and tube collection devices available for quick transportation of samples to the gas chromatographers. However, these collection devices usually do not store gasses for longer than 48 hours and actually cannot be used for long-term storage purposes. Furthermore, they are not designed to contain high-pressure gas and therefore would be an inefficient use of space for storage of many samples of breath gases. 


Technology Description

To respond to this unmet and crucial need, Dr. Pimentel and Dr. Rezaie from the Cedars-Sinai Medical Center have developed a system and associated method for long-term breath gas storage and sampling.



• Specific capsule design allows for long-term storage

• Capacity for high-pressure storage enables reduced storage space

• Ability to repeatedly use the same sample for multiple projects due to the valve type
