There is provided a humidification system for a breathing circuit that can detect abnormality in flow of intake air inside an inspiration tube. A humidification section is arranged inside an inspiration tube of a breathing circuit. Further, the humidification system is constructed capable of supplying moisture into intake air flowing inside the inspiration tube by using, for example, hydrophobic hollow fibers or a hydrophobic membrane. The flow section comprises a supply section for supplying moisture to the humidification section and a delivery section for delivering moisture that has been supplied to the humidification section. The control section detects intake air abnormality using difference information for water temperature of the supply section and water temperature of the delivery section.

1. A humidification system for a breathing circuit, comprising: a humidification section, a flow section, a control section, a reservoir, and a pump, wherein the humidification section is constructed using one of hydrophobic fiber and hydrophobic membrane wherein heated water can pass through inside one of the hydrophobic fiber and the hydrophobic membrane,the humidification section being arranged inside an inspiration tube of the breathing system,the humidification section being constructed to allow the heated water to pass through inside one of the hydrophobic fiber and the hydrophobic membrane to supply moisture derived from the heated water into intake air flowing inside the inspiration tube and flowing outside one of the hydrophobic fiber and the hydrophobic membrane,the flow section comprising a supply section for supplying the heated water to the humidification section, and a delivery section for delivering the heated water that has been supplied to the humidification section to the reservoir,the control section being configured to detect abnormality using difference information for the heated water temperature of the supply section and the heated water temperature of the delivery section, andthe pump being configured to apply pressure to the heated water for delivering the heated water to the supply section in positive pressure so that pressure of the heated water delivered to the flow section and the humidification section is higher than inner pressure in the inspiration tube of the breathing system. 2. The humidification system for a breathing circuit as disclosed in claim 1, wherein the humidification section is arranged close to a patient side end section of the inspiration tube. 3. The humidification system for a breathing circuit as disclosed in claim 1, wherein the supply section and the delivery section are constructed using flexible tube and wherein part or all of the supply section and the delivery section of the flow section is arranged inside the inspiration tube. 4. The humidification system for a breathing circuit as disclosed in claim 1, wherein the control section performs the abnormality detection on condition that a difference between the heated water temperature in the supply section and the heated water temperature in the delivery section is less than or equal to a specified value. 5. The humidification system for a breathing circuit as disclosed in claim 1, wherein the temperature of the heated water delivered to the supply section is set between about 60-70 degrees. 6. The humidification system for a breathing circuit as disclosed in claim 1, wherein the temperature of the heated water in the supply section and the heated water in the delivery section is measured outside of the inspiration tube. 7. A humidification system for a breathing circuit, comprising: a humidification section, a flow section, a control section, a reservoir, and a pump, whereinthe humidification section being arranged inside an inspiration tube of the breathing system,the humidification section being constructed to supply moisture derived from heated water into intake air flowing inside the inspiration tube,the flow section comprising a supply section for supplying the heated water to the humidification section, and a delivery section for delivering the heated water that has been supplied to the humidification section to the reservoir,the control section being configured to detect abnormality using difference information for the heated water temperature of the supply section and the heated water temperature of the delivery section, andthe pump being configured to apply pressure to the heated water for delivering the heated water to the supply section in positive pressure so that pressure of the heated water delivered to the flow section and the humidification section is higher than inner pressure in the inspiration tube of the breathing system. 8. The humidification system for a breathing circuit as disclosed in claim 7, wherein the humidification section is arranged close to a patient side end section of the inspiration tube. 9. The humidification system for a breathing circuit as disclosed in claim 7, wherein the supply section and the delivery section are constructed using flexible tube and wherein part or all of the supply section and the delivery section of the flow section is arranged inside the inspiration tube. 10. The humidification system for a breathing circuit as disclosed in claim 7, wherein the control section performs the abnormality detection on condition that a difference between the heated water temperature in the supply section and the heated water temperature in the delivery section is less than or equal to a specified value. 11. The humidification system for a breathing circuit as disclosed in claim 7, wherein the temperature of the heated water delivered to the supply section is set between about 60-70 degrees. 12. The humidification system for a breathing circuit as disclosed in claim 7, wherein the temperature of the heated water in the supply section and the heated water in the delivery section is measured outside of the inspiration tube.
