Embodiment 1
[0038] Melt and mix n-eicosane and n-docosane in different proportions to form a mixture with different phase transition temperatures, then crush the mixture and fill it in a grooved container with a diameter of 3 to 8 mm in sequence according to the phase transition temperature. In the groove of the ring-shaped transparent polyethylene plate ( figure 1 shown), and sealed with a ring cover after filling. The diameter of the transparent polyethylene plate ring is 1.5-3cm, the temperature scale line is arranged around the arc, the scale line length is 2-6cm, the grooves are arranged staggered along the scale line, and the groove size is 2×2mm 2 , 2mm deep. The temperature range is 35-42°C, and the temperature line interval is 0.2°C.
[0039] When in use, put the thermometer under the armpit or in the mouth, and place the groove area in the middle of the armpit or completely submerged in the mouth. Take it out after 1 minute, and the highest temperature corresponding to the ph...
