- the invention is directed to the detection problem of the blocked position of the respiratory device, and proposes a monitoring method and device for the blockage of the respiratory device, and specifically describes an embodiment of the monitoring method and device for controlling the blockage of the respiratory device:
- a method for monitoring clogging of a respiratory device includes:
- a detecting the pressure and flow of the inspiratory end and the expiratory end of the respiratory device
- a monitoring display 203 is disposed on the respiratory device host 201, and an inspiratory pressure sensor 207 is installed on the inhalation port 205 of the respiratory device.
- the inspiratory flow sensor 209, the airflow direction enters the analog user terminal 215 along the Y-shaped tee of the user airway 213 along the inhalation duct 211; on the other side of the respiratory device host 201, the exhalation of the respiratory device
- An expiratory pressure sensor 223 and an expiratory flow sensor 221 are disposed on the exhaust end 219 of the port 217, and the airflow direction enters the analog user end 215 along the exhalation duct 225 via the Y-type tee of the user end air passage 213.
- the data measured by the inspiratory pressure sensor 207, the inspiratory flow sensor 209, and the expiratory pressure sensor 223 and the expiratory flow sensor 221 are in error under the same pressure and flow rate conditions.
- the inspiratory tidal volume and the expiratory tidal volume and the minute ventilation amount of the user can be obtained by calculating the data of the above sensor, wherein the inspiratory tidal volume is calculated as the inhalation phase inspiratory flow sensor 209 and the expiratory flow.

- the pressure difference of the pressure sensors is compared, and the pipe blockage is considered to occur continuously over a certain period of time.
- the inspiratory tidal volume When the airway of the user end is blocked, if it is in the tolerance mode, the inspiratory tidal volume will be less than the set value. For the pressure control mode, the inspiratory tidal volume will be relatively small, so the user can be used with the feature of low tidal volume. End airway blockage judgment. The user's breath holding, inhalation, coughing, etc. can also cause a single inhalation The above phenomenon occurs in tidal volume. In order to prevent false alarms, it is necessary to judge the tidal volume of multiple breaths. That is, when the tidal volume of multiple breaths is lower than a certain value, it is considered that the airway of the user end is blocked, and the actual use of minute ventilation is performed. Judge.
- the duct is considered to be blocked.
