Abstract
The present invention relates to medical treatment cold compress physical therapy product technical field, specifically refer to a kind of for medical treatment plastic agent for storage of coldness of cold compress physical therapy and preparation method thereof.With polyvinyl alcohol 4% ~ 15%, medical glycerol 10 ~ 40%, surplus be water be raw material, make by adding medical glycerol after polyvinyl alcohol heating for dissolving, preparation technology is simple, easily operated, and product will make gelinite hard because being in for a long time under low temperature state, and plasticity is high, and gelinite will not change after thawing use, can be cost-effective with Reusability.
Description
Technical field
The present invention relates to medical treatment cold compress physical therapy product technical field, specifically refer to a kind of for medical treatment cold compress physical therapy plasticity
Agent for storage of coldness and preparation method thereof.
Background technology
Cold compress physical therapy is one of medical treatment conventional means, generally uses cold compress product to spread on diseased region, and main purpose is to promote
Make local vasoconstriction, control the hemorrhage of thin vessels and alleviate the pain of the bigger lump of tension force, reaching effect of reducing swelling and alleviating pain；Face
To hyperpyretic patient, can reduce body temperature after neck, neck by cold compress product cold compress, improve sense of discomfort.
The at present cold compress series products of commercial type, its internal agent for storage of coldness is the most specially treated liquid or cold compress is coagulated
Glue.Existing cold compress product in use, be placed in-20 DEG C ~-18 DEG C environment, freezing more than 4 hours, then takes out
Use.The typically cold compress product through freezing processing is easily frozen into lump, and plasticity is the highest, has hard when carrying out cold compress physical therapy
Foreign body sensation, at some human body specific paries, such as oral cavity, anus and need to change the portion that cold compress shape of product could use
Position, it is impossible to carry out cold compress immediately, need to be placed under normal temperature environment placement a period of time by cold compress product, treats its internal agent for storage of coldness tool
There is certain pliability, just can act on affected part, but so, the effect of cold compress is greatly diminished, to cold compress product
Use and also bring great inconvenience.
Summary of the invention
For the problems referred to above, the present invention proposes a kind of plasticity phase change cold accumulating agent and preparation method thereof, and this agent for storage of coldness is i.e.
Make to be in-20 DEG C～-18 DEG C of environment, freezing more than 4 hours, be maintained to certain plasticity and pliability.
To achieve these goals, the technical solution adopted in the present invention is: a kind of plasticity phase change cold accumulating agent, its raw material
For polyvinyl alcohol, medical glycerol, water.
Further, a kind of plasticity phase change cold accumulating agent, its raw materials by weight is: polyvinyl alcohol 4% ~ 15%, medical sweet
Oil 10 ~ 40%, surplus is water.
As preferably, described polyvinyl alcohol is medical grade polyvinyl alcohol.
Further, described plasticity phase change cold accumulating agent is solution state at normal temperatures, through-20 DEG C～-18 DEG C of freezings
After more than 12 hours, agent for storage of coldness is hydrogel state.
The preparation method of a kind of plasticity phase change cold accumulating agent as above, comprises the following steps:
1) weighing polyvinyl alcohol, medical glycerol, water are standby in proportion；
2) polyvinyl alcohol is added to the water, is heated to after polyvinyl alcohol is completely dissolved, it is thus achieved that poly-vinyl alcohol solution；
3) poly-vinyl alcohol solution prepared and medical glycerol are mixed, and stir, to obtain final product.
Processing technology of the present invention is simple, it is easy to operation.The agent for storage of coldness made will not be because being under low temperature state for a long time
Making gelinite hard, the position that can directly act on human body after freezing needs change shape to carry out cold compress carries out cold compress physical therapy,
And release cold effect and compare with like product, do not change；Using medical grade polyvinyl alcohol is raw material, has preferable cold-storage and makees
With, increasing cold compress effect and use the time, security performance is high；After thawing uses, gelinite will not change, can be repeatedly
Use cost-effective.
