Background
The nasal high flow humidification oxygen therapy (high-flow nasal cannula oxygen therapy, HFNC) in 2014 starts to be applied in China, and is rapidly popularized clinically in a short period of time, the clinical curative effect of the HFNC is widely accepted by clinicians, and a plurality of large-sample prospective clinical researches are sequentially published in recent years in the International journal of famous medicine, so that the HFNC is proved to have the treatment value in light and medium pure low oxygen respiratory failure (type I respiratory failure). Furthermore, HFNC has been shown to provide better clinical efficacy in patients with stable, slow pulmonary resistance (type II respiratory failure), and recent data also indicate that HFNC may play a role in the treatment of patients with acute exacerbations of slow pulmonary resistance. Currently, HFNC enters the rapid development and wide clinical application stage, and the international mainstream HFNC device adopts the working principle of a noninvasive ventilator: that is, the air-oxygen mixture is performed by an air-oxygen mixer, and the concentration of inhaled oxygen (FiO) 2 ) 21-100%, high flow gas is provided by using turbine, and heating and humidifying are performed by using breathing machineThe device and the pipeline heating heat conducting wire are used for heating and humidifying the inhaled gas in the whole process, and the temperature and the oxygen concentration are monitored in real time through the near-patient end to carry out dynamic regulation and control.
While the aerosol therapy (aerosol inhalation therapy) is to make bronchodilators, hormones or antibacterial drugs into aerosol, and deliver the aerosol or the aerosol into the airway and the lung, thereby achieving the purpose of treating diseases or relieving symptoms. In recent years, continuous innovation and improvement of the aerosol inhalation technology improves the drug output and inhalation efficiency, so that the concentration of the drug in the lung is increased. The small-capacity atomizer is a common clinical atomizing device, is mainly used in critical care units and emergency departments, is widely applied to clinical and family treatment at present, and is particularly suitable for infants and patients incapable of breathing coordination. The small-capacity atomizer mainly comprises a spray atomizer, an ultrasonic atomizer, a vibrating screen mesh atomizer and other structural forms, wherein spray atomization is one of common atomization methods, and oxygen or air can be used as a spray atomization air source.
Currently, patients who clinically receive HFNC treatment often need to perform aerosol inhalation treatment, but currently, a common way is to continuously perform aerosol inhalation through an aerosol mask at the same time of high-flow oxygen therapy, or to connect the high-flow inhalation through a T-shaped pipeline of an atomizer, and continuously perform aerosol inhalation during the whole inhalation and exhalation phases, or to disconnect the high-flow oxygen therapy and perform aerosol inhalation in a common way. Above-mentioned atomizing mode probably leads to exhaling a large amount of atomized medicine waste in the stage, and then causes atomization inefficiency, if adopt atomizing antibiotic then lead to the resistant probability to increase easily, in addition, can also lead to atomizing granule to be blockked by the nasal obstruction pipe of high flow oxygen therapy through the face guard atomizing inhalation, atomizing granule can't get into the respiratory track, high flow oxygen therapy is also not recommended clinically and is carried out atomizing inhalation through mouth and face guard simultaneously, high flow oxygen therapy is also not recommended simultaneously to break off, this can lead to high flow oxygen therapy breathing support's interruption, in addition, atomizing cost is also higher to valuable medicine. The above-described problem is clearly solved if an automatic identification of patient inhalation and start of the nebulization function, i.e. nebulization therapy only during the inhalation phase and nebulization is stopped during the exhalation phase, can be achieved on a high-flow oxygen therapy device.
