Description
Technical field
The invention belongs to bring down a fever in the biological medicine material refreshment paste and preparation field thereof, particularly a kind of BC that is used to generate heat auxiliary treatment and emergent physical cooling bring down a fever refreshment paste and preparation thereof.
Background technology
Bacterial cellulose (Bacterial Cellulose, BC) be a kind of by the synthetic native cellulose of microorganism, see from molecular formula what difference BC and common plant cellulose do not have, but give its high mechanical strength and biocompatibility because of physics, the chemical constitution of uniqueness.The BC that is shaped is made of the fiber of highly crystalline body and highly single guiding banded superfine fibre, intricately is intertwined and forms unique tridimensional network, the unique tridimensional network of BC inside has a lot " duct ", high ventilation, water permeability are arranged, can absorb 60～700 times of moisture content to its dry weight, these moisture are that the form with Free water exists.Use BC can take away the heat of skin as the substrate of the refreshment paste of bringing down a fever by the evaporation of the Free water that wherein is rich in.Simultaneously cellulose not can with the skin adhesion, do not have residual when peeling off yet.
The refreshment paste of bringing down a fever of report mainly is substrate with the non-woven fabrics at present, and coating one deck high molecular weight hydrophilic gel covers one deck isolation protection film more above.Wherein contain natural refrigerant fragrant volatile plant essence oil in the hydrophilic macromolecule gel layer, this quintessence oil has the effect of heat clearing away refreshment.But find the effect and not obvious of bringing down a fever of this refreshment paste of bringing down a fever through overtesting, the contained Free water of high-molecular gel layer wherein seldom can not be taken away the heat of skin by the evaporation of moisture, and only by refrigerant sensation that quintessence oil brought.At present, do not see both at home and abroad the research and development report of the bacteria cellulose-based febrifugal refreshment paste of be used to generate heat auxiliary treatment and emergent physical cooling as yet.
Therefore the bacteria cellulose-based febrifugal refreshment paste of auxiliary treatment and emergent physical cooling of being used to generate heat has very large application prospect in the bio-medical material industry.Simplify production technology simultaneously, reduce production costs BC the applying of refreshment paste of bringing down a fever also played very big impetus.
Summary of the invention
Technical problem to be solved by this invention provides a kind of BC that is used to generate heat auxiliary treatment and emergent physical cooling bring down a fever refreshment paste and preparation thereof, this bacteria cellulose-based febrifugal refreshment paste moisture content height, water evaporates can effectively be taken away the human heat, good biocompatibility, adhesion is chafe not also, safety and environmental protection; And preparation method is easy, and is easy to operate, with low cost, environmentally friendly, has a good application prospect.

4, the bring down a fever effect of bringing down a fever of refreshment paste of the BC for preparing adopts following method to estimate
The prepared refreshment paste and commercially available defervescence plaster used of bringing down a fever of BC film that is obtained by different incubation times that area is identical is wrapped on the vacuole of mercurial thermometer.Be positioned over then in the calorstat,, measure the different defervescence plaster used thermometeies that wrap up under about 20% condition of ambient humidity 0～5 hour registration situation of change at 39 ℃.
Experimental result is seen Fig. 5, and the result shows that under 39 ℃ the various defervescence plaster used thermometer registration rates of change that wrap up 3h before experiment changes greatly.The commercially available defervescence plaster used thermometer registration rate of change that wraps up is 4.6 ℃/h in the 1h, and incubation time is that 4,7,10 days defervescence plaster used thermometer registration rates of change that wrap up of prepared BC then are respectively 4.7 ℃/h, 4 ℃/h and 3 ℃/h; The commercially available defervescence plaster used thermometer registration rate of change that wraps up is 7.25 ℃/h in the 2h, and incubation time is that 4,7,10 days defervescence plaster used thermometer registration rates of change that wrap up of prepared BC then are respectively 6.5 ℃/h, 6.5 ℃/h and 5.5 ℃/h.All illustrate of the present invention defervescence plaster used can be than the commercially available defervescence plaster used more frequent fever amount of taking away; In the 3h, the commercially available defervescence plaster used thermometer registration average rate of change of wrapping up is 5.5 ℃/h, and incubation time is that 4,7,10 days defervescence plaster used thermometer registration average rate of change of wrapping up of prepared BC then is respectively 6 ℃/h, 6.5 ℃/h, 6 ℃/h.This is after scattering and disappearing owing to the moisture in defervescence plaster used is a large amount of, can not walk heat by the evaporator strip of moisture again, thereby delay the rising of temperature, and this moment, defervescence plaster used internal and external environment temperature was almost consistent, no longer there are differences.
Conclusion: in the time of 39 ℃, be wrapped in BC and bring down a fever that to compare the commercially available defervescence plaster used rising of parcel slow for the thermometer registration of refreshment paste, this explanation BC refreshment of bringing down a fever is posted more water evaporates and is taken away heat, and plays the effect of better bringing down a fever; And be wrapped in by the thermometer registration of cultivating 10 days the made refreshment paste of bringing down a fever of BC film rise the slowest.But in the time of 39 ℃, this difference neither be very big.
