Method for controlling a thermoregulated ventilation circuit
The present invention relates to a method for controlling a thermoregulated ventilation circuit ( 100 ) equipped with a control unit ( 40 ) and comprising an active humidifier ( 10 ). The active humidifier ( 10 ) further comprises, in turn, a cartridge ( 20 ) equipped with a humidification chamber ( 21 ) adapted to contain water to be heated for the humidification of the air through a heating element ( 30 ), and the thermoregulated circuit ( 100 ) further comprising at least one intake tube ( 120 ) for conveying the air exiting said cartridge and provided with heating means ( 123 ) for heating the air exiting said cartridge ( 20 ). The method according to the present invention is characterised in that said control unit ( 40 ) receives in input the patient's temperature data (Tp) detected by a patient's temperature probe ( 132 ) and regulates the operation of said heating element ( 30 ) of said cartridge ( 20 ) and the operation of said heating means ( 123 ) of the air exiting said cartridge ( 20 ) as a function of said patient's temperature (Tp).
1. A method for controlling a thermoregulated ventilation circuit equipped with a control unit and comprising an active humidifier, said active humidifier comprising, in turn, a cartridge provided with a humidification chamber adapted to contain water to be heated for the humidification of the air through a heating element, said thermoregulated circuit also comprising at least one intake tube for conveying the air exiting said cartridge and equipped with heating means for heating the air exiting said cartridge, the method comprising:
said control unit receiving an input of a patient's body temperature data detected by a patient's internal body temperature probe; and
automatically regulating the operation of said heating element of said cartridge and the operation of said heating means of the air exiting said cartridge as a function of said patient's body temperature.
2. The method for controlling a thermoregulated ventilation circuit according to claim 1 , wherein said patient's body temperature is detected continuously by said patient's internal body temperature probe, and said control unit continuously receives the patient's body temperature data in input and regulates the operation of said heating element and said heating means of the air with every change in patient's body temperature.
3. The method for controlling a thermoregulated ventilation circuit according to claim 2 , wherein said control unit acts on the heating means of the air so that the temperature of the air exiting the ventilation circuit is automatically regulated by the control unit based on the patient's body temperature detected by said patient's internal body temperature probe.
4. The method for controlling a thermoregulated ventilation circuit according to claim 3 , wherein said control unit receives in input, as well as the patient's body temperature, the value of the temperature of the air exiting the cartridge read by a first thermistor.
5. The method for controlling a thermoregulated ventilation circuit according to claim 4 , wherein said control unit also receives as input data the temperature value of the air exiting the intake tube detected by a second thermistor.
6. The method for controlling a thermoregulated ventilation circuit according to claim 5 , wherein said control unit regulates the electric power supplied to said heating element of said cartridge based on the temperature value read by said first thermistor.
7. The method for controlling a thermoregulated ventilation circuit according to claim 5 , wherein said control unit regulates the electric power supplied to said heating means for heating the air exiting said cartridge based on the temperature value read by said second thermistor.
8. The method for controlling a thermoregulated ventilation circuit according to claim 1 , wherein said control unit is equipped with a control display so as to allow the manual adjustment of the temperature parameters of the air exiting the intake tube and of the value of humidity contained in such air to be set by the user.
9. The method for controlling a thermoregulated ventilation circuit according to claim 1 , wherein said control unit receives in input the value of the inner temperature of the heating element of said cartridge from a thermistor integrated in said heating element.
10. A thermoregulated ventilation circuit comprising:
an active humidifier, comprising, in turn, at least one cartridge provided with a humidification chamber adapted for containing water to be heated for the humidification of the air through a heating element;
at least one intake tube to convey the air exiting said cartridge and equipped with heating means for heating the air exiting said cartridge;
at least one acquisition connector for the connection of a patient's temperature probe; and
a control unit configured to receive in input patient's body temperature data detected by said patient's internal body temperature probe, and regulate the operation of said heating element of said cartridge and the operation of said heating means of the air exiting said cartridge as a function of said patient's body temperature.
