Description
Technical field
The present invention relates to a kind of glass-stem thermometer measurement medium, more particularly to a kind of clinical thermometer with mercury-free liquid alloy and
Clinical thermometer.
Background technology
The clinical thermometer of measurement human body temperature or animal heat is presently used for, is mostly glass-stem thermometer, and mercury conduct
The clinical thermometer of temperature carrier, can volatilize at a temperature of more than 17t, either in the production process of glass-stem thermometer, still
When being damaged during its use, it can all damage to health.For since environment can be endangered using the larger mercury of toxicity
And human body, mouth have been used by limitation outside.Therefore, Mercury-free clinical thermometer is with a wide range of applications.
It is directed to developing Mercury-free clinical thermometer both at home and abroad now, but can effectively substitutes the liquid alloy carrier of mercury to be one
Main key problem in technology.The Chinese patent of Application No. CN03112638.3 discloses a kind of Inductive temperature liquid for glass-stem thermometer, institute
State Inductive temperature liquid for glass-stem thermometer, including following material：45~60 parts of gallium, 20~32 parts of indium, 9~15 parts of tin and 9~
15 parts of zinc, is made through mixing, heating.This temperature sensing liquid, it is nontoxic and will not volatilize, it will not damage to health.
It can be used as measuring the measurement medium of the glass-stem thermometer of human body temperature or animal heat.Patent CN1039162C proposes one kind and contains
The liquid alloy temperature carrier of Ga 65-95, In 5-22, Sn 0-11, Sb 0-2, Bi 0-2, patent CN1142415C propose one
Kind of composition (wt%) be Ga50-67, In23-30, Sn6-16, and Cs0.01-10, Rb0.01-10, the low of Zn0.5-5 are total to solution body
Alloy can be used as clinical thermometer temperature carrier.
But the fusing point of existing mercury-free liquid alloy is although relatively low, may replace mercury under certain condition.But they are protected
The stability for holding liquid still dislikes inadequate.When temperature relatively low (as being less than 5 DEG C) or component fluctuate, deviation and crystallization are easily produced,
Liquid is in viscous pasty state, influences the temperature measuring of temperature carrier.On the other hand, expensive In contains in the alloy described in these
Measure excessive, some also contains the precious metals such as Cs, Rb, this causes liquid alloy selling at exorbitant prices, influences the cost of clinical thermometer, becomes
The serious restraining factors that Mercury-free clinical thermometer promotes and applies.
Further, since liquid alloy is different from mercury surface tension, the adsorption capacity of they and glass tube walls is also significantly greater than mercury
With the adsorption capacity of tube wall, therefore the necking down structure of mercury clinical thermometer glass tube is being measured for the clinical thermometer alloy of new liquid alloy
Afterwards it is difficult to reply, influence body fluid alloy and freely up and down flowed by necking down structure.
The content of the invention
In view of the deficiencies of the prior art, the object of the present invention is to provide a kind of clinical thermometer mercury-free liquid alloy and body temperature
Meter, it has the characteristics that good fluidity, thermometric accuracy rate are high.
