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...

Abstract

The invention discloses a disposable annular thermometer. The disposable annular thermometer is mainly used for measuring a body temperature. The disposable annular thermometer is prepared from organic matters and can be burned after use. Phase-change material powder is arranged in a plastic annular container and a body temperature is characterized through phase change of different phase-change materials at different temperatures. The phase-change materials comprise aliphatic hydrocarbons, fatty alcohols, aliphatic acids and aliphatic esters. The aliphatic hydrocarbons comprise n-nonadecane to n-tetracosane. The fatty alcohols comprise n-tridecanol to n-hexadecanol. The aliphatic acids comprise n-decadecanoic acid to n-octadecanoic acid. The aliphatic esters comprise methyl stearate, ethyl stearate, methyl nonadecanoate, ethyl nonadecanoate, methyl arachidate and ethyl eicosadioate. The phase-change material with different phase-change temperatures is a mixture of two or three different phase-change materials. The disposable annular thermometer is cheap, does not need disinfection and can be treated easily.

Description

technical field [0001] The invention relates to a disposable ring thermometer. Background technique [0002] There are three types of medical thermometers, glass mercury thermometers, electronic thermometers and ear thermometers. Three kinds of thermometers are all expensive, and cannot be used in one go. Reusable thermometers need to be disinfected after each use. If the disinfection work is not in place, it may lead to cross-infection. [0003] After searching, it is found that the currently valid utility model patent for disposable thermometers (application number: N200610029740) is made using the principle of liquid thermal expansion and cold contraction, and glass is still used in the selection of materials, and it also needs to be used in the treatment of medical waste. classification processing. Contents of the invention [0004] In order to meet the objectives of the disposable ring thermometer being cheap, no need to sterilize and easy to handle, the present in...
