The transfer tube 1 comprises a tube 2 and a thermochromic sheet 3. The tubular body 2 has a Y-shaped connecting portion 21 and two long tubular portions 22, the γ-shaped connecting portion has two branching ports 211 and a confluence port 212, and each of the branching ports 2 is connected to the long tube portion 22, and the tubular body 2 is defined A passage 20 for the fluid to flow in and out. The tubular body 2 further has a groove 23 provided in the γ-shaped connecting portion 21 and recessed inwardly from the outer surface, so that the wall 2 between the groove 23 and the channel 2 is thinner, and the wall can be reduced. The thickness affects the heat conduction and accelerates the heat transfer rate' while the temperature sensitive color changing sheet 3 is disposed at the groove 23, and is attached to the surface of the tube 2 to sense the fluid in the channel 20 (the gas in this embodiment) Warm production. In the present embodiment, the thermochromic sheet 3 is used to monitor the wetness of the channel 2 () (10). The thermochromic sheet 3 has a preset π 燹 chromatic cylinder circumference. Since the transfer tube 1 is used for non-invasive treatment or invasive treatment, the temperature of the delivered gas is slightly different from 201125603 when the transfer tube 1 For non-invasive treatment, the delivered gas undergoes normal nasal breathing, and the required gas temperature is approximately 31 to wc, when the delivery tube 1 is used for invasive treatment, such as intubation therapy and gas incision cannulation 'The required gas temperature is about 37 to 40 ° C, depending on the transfer tube! For non-invasive treatment or invasive treatment, the thermochromic sheet 3 corresponding to the color temperature range of the safety gas temperature is selected. When the transfer tube 1 is used for non-invasive treatment, the selected thermo-sensitive color change sheet 3 can be converted into three colors, corresponding to a first color according to the sensing temperature range of 31 to 34 ° C, exceeding the aforementioned temperature range (ie 34) °C) corresponds to a second color, and corresponds to a third color below the temperature range (ie, 31 ° C), wherein the first color, the second color, and the third color are respectively different colors. When the transfer tube 1 is used for invasive treatment, the selected thermo-sensitive color change sheet 3 can also be converted into three colors, corresponding to a first color according to the sensing temperature range of 37 to 40 ° C, exceeding the aforementioned temperature range (ie 40 °C) corresponds to a second color, and corresponds to a third color below the aforementioned temperature range (ie, 37 ° C). By the thermochromic sheet 3 exhibiting a different color 'the temperature of the gas in the channel 20 can be monitored to maintain the gas within an appropriate temperature range. Referring to Figures 4 and 5, a second preferred embodiment of the transmission tube having a thermochromic sheet of the present invention is also applicable to a respiratory medical device for transmitting a gas that is breathed by a human body. The transfer tube 1' includes a tube 2' and a thermochromic sheet 3'. The tubular body 2' has a Y-shaped connecting portion 21' and two long tubular portions 22'.
