Vapotherm (Stevensville, Maryland), a developer of high flow oxygen therapy products reported that its U.S. patent rights have been validated for an apparatus used in the delivery tube technology for respiratory tract therapy. U.S. Patent No. 7,314,046 B2 has been granted through 2022.

The company says that the triple-lumen design is "the vital component for Vapotherm products as it helps deliver humidified air to the respiratory tract of patients." Used throughout all Vapotherm products, including the 2000i and the recently introduced Precision Flow, the apparatus allows Vapotherm to maintain the conditioned breathing gases to the patient to aid in respiratory tract therapy and treatment.

"Our patient delivery circuit design is unique in the field and provides Vapotherm with a competitive advantage through the delivery of optimally conditioned breathing gases all the way to the patient, whereas conventional approaches can result in significant temperature and humidity loss," said William Niland, chief business development officer and company chairman.
