Such as according to national statistics office data in 2009,58797.8 ten thousand tons of national special medical water consumption.Wherein Guangdong Province is complete
6044.1 ten thousand tons of medical water is saved, accounts for the 10.28% of the medical water in the whole nation, market scale is very big.Pearl River Delta, Guangdong Province are
There is natural rigidity to the medicinal water purification of more depth or bactericidal unit and the relevant technologies to each medical supply unit of national hospital
Demand also remains long-term, the stable market demand.
Due to life security and the health of the masses of concerning, State-level is to the medical professionalisms such as injection, haemodialysis water product
Quality supervision pipe is increasingly stringent, successively puts into effect《Blood purification standard practice instructions》(version in 2010),《Purified water and injection water gauge
It is quasi-》(2015 editions pharmacopeia),《Medical instrument process water quality management guide (2016 No. 14)》,《Medical institutions are medical
The water hygiene requires (2018 paper for approval)》It (is taken charge of the explanation by People's Republic of China's health and Family Planning Committee, drafting unit
Including Peking University First Hospital etc.) etc. national standards or system, medicinal water is supervised safely from system, source,
Ensure medicinal water safety.This virtually proposes requirements at the higher level with advanced water treatment technology to professional medicals such as injections.
Existing medical professionalism water treatment technology is very different, and some existing medicinal water purification techniques, which still face, to be remained
The risk of machine, inorganic pollution or remaining bacteria.Some existing purification processes are excessively high in cost, cause to relevant enterprise larger
Burden.Medicinal water is made by oneself even with boiling method in the rural medical institutions of part, and medical water safety causes anxiety (Yu Qinger, land
It is flat, Mao Jianxun, wait boiling method prepare medicinal water clinical use observation [J] Chinese countryside Hygienic Undertaking Management, 2006,26
(4):27-27).The investigations such as Shao Weidong discovery, Zhejiang Chinese & Western Medicine Hospital's department of stomatology is in December, -2009 in January, 2008
In period department of stomatology medicinal water, mobile phone water spray hygienic quality qualification rate is 23.1%, triple syringe water spray hygienic quality qualification rate
It is 42.0%.The 3-9 month in 2010, after department of stomatology medicinal water adds filter device, mobile phone water spray hygienic quality qualification rate is
24.7%, triple syringe water spray qualification rate is 36.1%, and source water quality pass rate is 50.0%, and medicinal water safe mass is born
Sorrow, the improvement of simple plus filter effect is unobvious, and (Shao Weidong, Li Yanjuan, Zheng Gang wait department of stomatology medicinal water germ contamination control

Water service condition carries out fishing expedition, spot sampling, bacterial monitoring.Monitoring display：Medicinal water bacterium is exceeded to be concentrated mainly on
The department of stomatology, Drug Manufacturing Room, department of stomatology medicinal water pollute account for the first (Sun Xiao, Hua Weihong, flat medicinal water monitoring and quality control
Tubulation manages [J] modern medicine health, 2011,27 (19):3025-3026).It is attached that Jin Shaozhi etc. reports Medical College of Zhejiang Univ.
The relatively successful experience of Shu Shaoyi husband hospital：The institute establishes medical purifying water system when constructing from capital construction first stage of the project in 1993
System, prepares medical purified water using reverse osmosis technology, is each clinical department of hospital such as haemodialysis, operating room, emergency ward, inspection
Section, the department of stomatology, Pharmacy etc. provide qualified medicinal water.With the expansion of hospital size, medical department is continuously increased, former
It designs the dosage for producing 3 tons of purified water per hour used and has been unable to meet the demand of curative activity, therefore extended the second phase in hospital
Cheng Zhong has created the reverse osmosis purified water system that water yield is 5 tons per hour.The second stage of the project has been drawn first stage of the project and has actually been made
With experience in the process, improve automatic control mode, make full use of purified water waste water produced during the preparation process (Jin Shaozhi,
Jin Chunrong hospital's water purification system and energy-saving design apply [J] China Health quality management, 2003 (6):64-64).Chen Shunhua
Design thoughts application of the hollow fiber ultrafiltration membrane in medicinal water, and the further investigated selection of film, cleaning, disinfection and maintenance
Technical essential, proved technology advantage (Chen Shun China doughnut in terms of degerming, depyrogenation ability, transfusion stabilization
Possibility research [J] pharmaceutical engineering design of the ultrafiltration membrane in medicinal water preparation, 1998 (2):12-14).
As described above, domestic existing medicinal water still meets with certain bottleneck in terms of purification, one
A little medicinal waters face larger security risk.If using the medicinal water for still having residual contaminants or remaining bacteria pollution, easily
Great malpractice is caused, health of the masses is endangered.Purification and sterilizing are also called thoroughly, efficiently in market, the easy inexpensive doctor of device
Treat profession Water warfare new technology and relevant apparatus.
