A gas delivery device is disclosed, the gas delivery device comprising a lumen configured to route a gas into the respiratory system of a mammal, a first meter configured to measure the concentration of nitric oxide gas present in the lumen, a second meter configured to measure the rate of gas flow in the lumen, and a dosimeter that integrates the concentration of nitric oxide measured in the lumen with the rate of gas flow measured in the lumen to determine the amount of nitric oxide delivered by the device to the respiratory system of the mammal. The device may further comprise a vessel with pressurized gas comprising with at least 1 ppm nitric oxide, the vessel having a mechanism for controllably releasing the pressurized gas into the lumen or into a chamber in communication with the lumen. The release of the pressurized gas may be triggered by negative inspiratory pressure of the mammal and limited to the inspiratory cycle of respiration.
本发明公开了一种气体输送装置,该气体输送装置包括一个用于将气体输送到哺乳动物呼吸系统的管腔、一个用于测量管腔中一氧化氮气体浓度的第一测量仪、一个用于测量管腔中气体流速的第二测量仪,以及一个剂量计,该剂量计将管腔中测量到的一氧化氮浓度与管腔中测量到的气体流速进行整合,以确定该装置输送到哺乳动物呼吸系统中的一氧化氮量。该装置可进一步包括一个装有加压气体的容器,加压气体中至少含有 1 ppm 的一氧化氮,该容器具有一个机构,用于将加压气体可控地释放到管腔中或释放到与管腔相通的腔室中。加压气体的释放可由哺乳动物的负吸气压力触发,并仅限于呼吸的吸气周期。
