Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of medical antibacterial type lucifuge igelite.
Background technology
21 century is the period of World Medical apparatus fast development, along with China's reform and opening-up quickening of paces, people
Living standard and quality of life improve constantly, and medical and health care system is had higher requirement by people.This will necessarily promote doctor
Treat the quick growth in apparatus market, provide wide development space the most also to China's medical plastic product.
Plastics because of excellent performance, the advantage such as cheap and handling ease, obtain more and more extensive at medical field
Application, its importance day by day shows especially.Up-to-date statistics shows, the total capacity of China's Medical Device Market there are about 150,000,000,000 people
Coin, one of current China ten big emerging markets having become as global medical apparatus, are the medical treatment of Fia in addition to Japan
Apparatus market, wherein disposable medical plastics article can improve medical treatment level with it, is prevented effectively from cross-infection and is manufactured into
This advantage such as the lowest and obtained in the whole world being increasingly widely applied.
The Medical transfusion pipe of prior art, woven hose, infusion bag, conduit, intubate with the products such as oxygen mask be the most all by
Medical polyvinyl plastics is made.Medical polyvinyl plastics has a wide range of applications in Medical Devices, is primarily due to
Medical polyvinyl plastics itself has good physical property.These physical propertys include: medical polyvinyl plastics manufacture
Convenience and the compatibility good between parenteral solution and blood of this kind of material and vein (intravenous, IV), so
In terms of medical treatment, this plastic products function admirable, easy to use, the most popular with users.But pure PVC material, its hardness
All cannot meet medical needs with flexibility, plasticizer need to be added it is modified.The effect of plasticizer is: increase polymer
Flexibility, percentage elongation or process (processing) convenience.Plasticised polyvinyl chloride class material also have be more easy to sterilization, more transparent
Feature, and there is more preferable chemical stability and economic validity.At present, the most frequently used for PVC plasticizer is phthalic acid
Di-isooctyl (DOP), but in recent years, the wholesomeness about DOP is disputed on more.European Union determined to forbid in July, 2005
Use the o-benzoic acid esters plasticizer such as DINP；Japan also will add one with soft PVC in food hygiene amendment
In the toy manufactured, prohibit the regulation containing phthalic acid composition.Based on this situation, exploitation toxicity is lower than DOP, migration precipitation
The new plasticizer less than DOP is imperative, and including the citric acid ester type that oneself wholesomeness through developing is good, molecular weight is big
Polyesters and other various polymeric plasticizers.But, these plasticizer still suffer from plasticization effect and include flexible under low temperature and add
Work etc. not as DOP, the shortcoming such as expensive.Exploitation can overcome the plasticizer of drawbacks described above to be igelite research
One important directions.
Additionally, on the one hand, light note promotes some drugs generation photochemical degradation, reduces the curative effect of medicine, produces patient
Harmful effect.Medical polyvinyl plastics is commonly used for preparing lucifuge medical devices, it is common that adds in igelite and keeps away
Photo etching or dyestuff are to meet medical equipment lucifuge requirement, and the lucifuge agent added or dyestuff can to a certain degree be dissolved into liquid
In, and these medical plastic light transmittances are mostly more than 30%, do not reach lucifuge purpose, have a strong impact on the quality of infusion medicine, can
The most serious consequence and harm can be brought to patient.On the other hand, in everyday environments, bacterium, mould etc. are caused a disease
Property microorganism is ubiquitous, and the moment threatens the health of the mankind.The development of anti-biotic material and application, can effectively reduce or avoid thin
The cross infection of bacterium and transmission of disease.The research and development of antimicrobial form polyvinyl chloride are more and more eager.
Summary of the invention
For the defect of prior art, the technical problem to be solved is to provide a kind of with ionic liquid as plasticising
The medical antibacterial type lucifuge igelite of agent.
For solving the problems referred to above, the technical solution used in the present invention is:
