9. A heat preservation method of a heat preservation type effusion censorship test tube for an endocrinology department comprises the following steps:
heat exchange media are stored in a medium space (12) formed by the inner wall of the outer pipe body (1), the outer wall of the inner pipe body (2) and the inner cover surface of the cover body (3),
liquid loading is stored in a liquid loading space (23) formed by the inner wall of the inner pipe body (2) and the inner cover surface of the cover body (3),
it is characterized in that the preparation method is characterized in that,
the inner tube (2) is arranged in such a way that its thermal conductivity is greater than the thermal conductivity of the outer tube (1) and the thermal conductivity of the cover (3),
a heat exchange circulation passage which can lead the heat exchange medium from the medium space (12) to the liquid accumulation space (23) and is used for enabling the temperature of the liquid accumulation to be uniformly distributed is arranged in the liquid accumulation space (23), so that when the ambient temperature is higher than the active temperature of the liquid accumulation, the liquid accumulation can transfer heat to the heat exchange medium through the heat exchange circulation passage and the wall surface of the inner pipe body (2) under the condition that the medium space (12) and a refrigerating device (4) form a refrigerating circulation channel which can cool the heat exchange medium; or when the environment temperature is lower than the active temperature of the accumulated liquid, the heat exchange medium can transfer heat to the accumulated liquid through the heat exchange circulation passage and the wall surface of the inner pipe body (2) when an electric heating piece (6a) arranged in the medium space (12) is electrified.
10. A method according to claim 9, characterized in that the refrigerating device (4) is capable of forming with the medium space (12) a refrigerating cycle channel which reduces the temperature of the medium, whereby the liquid charge is capable of transferring heat to the medium through the inner tube (2) and the heat exchange cycle passage in such a way that its temperature is maintained within its active temperature range.
