Definitions
- the present invention relates to an apparatus for measuring the temperature of inspired air used for artificial respiration, particularly the temperature of inspired air in a breathing circuit.
- a humidifier is installed in the middle of the intake channel to provide necessary humidity to the intake.
- the intake air may be cooled by room temperature in the middle of the intake passage. This not only lowers the temperature of the inspired air itself, but also reduces the amount of saturated water vapor, resulting in dew condensation, which may cause a problem that the inhaled humidity at the time of delivery to the patient may decrease. This problem is not negligible if the child is a patient with weak respiratory function.
- a temperature sensor that detects the intake air temperature in the flow path is provided to appropriately control the temperature of the heater.
- a heater for heating the inside for example, an infrared heater, is arranged in the incubator. Therefore, if the temperature sensor is placed in the incubator, the temperature sensor may be heated by the heater and the detection accuracy may be degraded.
- the temperature sensor outside the incubator.
- the sensor detects the temperature of the inspired air at a position distant from the patient.
- the disturbance conditions for the inspired air after heating (example For example, cooling at room temperature) must be predicted.
