Description
Technical field
The present invention relates to a kind of new medical is defervescence plaster used, be specifically related to it is a kind of in use can changing according to color
Become and intuitively observe that the temperature-sensitive three-level discoloration of body temperature situation of change is medical defervescence plaster used, belongs to the field of medical instrument technology.
Background technique
Children fever is one of the cardinal symptom for threatening children's health, especially low fever's phenomenon of underage child group, because
Be not easy to express its subjective feeling for one side underage child, on the other hand, due to the factors such as environment influence, low fever tend to by
Ignore, which results in the delays of the state of an illness, gently then affect the normal development of children, heavy then can cause life threat to children;Cause
This, in order to which the generation of such carelessness is effectively reduced, it is defervescence plaster used that discoloration occurs in market, on the one hand can be directly by defervescence plaster used
Color change and the physical condition for recognizing patient, on the other hand being capable of fast cooling treatment.
Change colour defervescence plaster used because of its validity and convenience, so that it has just been liked by the majority of consumers since listing, closely
It several years, is constantly innovated by industry, various Novel color-changings are defervescence plaster used to put goods on the market in succession.
However, it is all that can only become two colors that discoloration currently on the market is defervescence plaster used, i.e., it can only distinguish fever and have no temperature,
Low fever and high fever cannot be effectively highlighted, and is very different for the therapeutic scheme of low fever and high fever, especially for baby
This kind of special population, in order to not influence its normal growth and development, unless last resort, general it is not recommended that therefore medication is opened
Send out that a kind of three-level discoloration that can highlight low fever and high fever is defervescence plaster used to have more practical value;In addition, currently used heat
Sensitive allochromatic material is easy to react with outside environmental elements such as water etc., is easy to happen physical chemistry in the case where no protection
Matter changes, and so as to cause product failure, therefore, the thermo-sensitive material for how solving conventional type is easy to maintain, easily change affected by environment
The defect of matter color development is the method for industry research.
Summary of the invention
The object of the present invention is to provide a kind of temperature-sensitive three-level discoloration it is medical defervescence plaster used so that the variation of color can not only be passed through
The physical condition of user is got information about, and can also be provided just by colouring discrimination high fever or low fever for further treatment
Benefit accelerates Rehabilitation rate.
Change colour medical defervescence plaster used preparation method it is a further object of the present invention to provide the temperature-sensitive three-level, by its technique
Optimization determine, on the one hand, promoted its change colour sensitivity, on the other hand, promote defervescence plaster used mechanical performance, thus promoted in fact
The property used.
Technical scheme is as follows:
A kind of temperature-sensitive three-level discoloration is medical defervescence plaster used, including spunlace non-woven cloth base fabric, thermosensitive aquagel layer and PP isolation film, temperature-sensitive
Hydrogel is applied in spunlace non-woven cloth base fabric, then goes up PP isolation film again to obtain the final product;Wherein, thermosensitive aquagel layer directly contacts people's
Skin absorbs human heat in colloid, then takes away intracorporal heat by the large quantity of moisture rapid evaporation stored in hydrogel
Amount, to play cooling effect.
A kind of medical defervescence plaster used preparation method of temperature-sensitive three-level discoloration, includes the following steps:
