Medical and welfare facilities that have a direct impact on people's lives require a higher level of reliability and safety. With the continuous improvement of people's quality of life and the arrival of an aging society, the market for medical and welfare homes is gradually expanding, and hospital facilities and equipment need to be upgraded and increased. Copper tubing plays a major role in achieving safety and providing a comfortable environment. Copper tubing enjoys high ratings for its durability, corrosion resistance, antimicrobial properties, and economy, and has been identified as the material of choice by experts in the design of medical and welfare facilities.
According to market statistics on the status of tubing used in medical buildings, the market share of copper tubing in the cold water pipe market for water supply systems is about 22% to 25%; in the hot water pipe market, the market share of copper tubing is about 54%?61%. Medical gas systems in the oxygen pipe market, copper pipe market share of about 75% to 85%; negative pressure suction pipe market, copper pipe market share of about 46%?50%.
In terms of foreign medical gas systems, the U.S. NFPA99C specification is updated every three years to provide useful guidance on the manufacture of equipment products, copper tube product standards have ASTMB819-2000 "medical gas devices with seamless copper tubing"; the UK's HTM2022 specification contains the statement, customary practices, design, operation, Management of five aspects, very detailed. European **** body has EN737 "medical gas piping system", copper tube product standards have BSEN13348:2001 "copper and copper alloy? Seamless round copper tubes for medical gas or vacuum".
In our country, the medical building in the gas system has no special acceptance standards, but only the use of a number of industrial standards, norms, these standards, norms and conflict with each other, in the use of the specification preparation date has been a long time, backward and incomplete, do not adapt to the needs of today's hospital construction. In addition, the diameter of the medical gas pipeline, coloring the situation is different, the design level is uneven, there is no perfect medical gas design and construction acceptance regulations to support the guidance, which is difficult for the maintenance of equipment and management. At present, the medical, construction system has entered the development of medical buildings in the gas system standards, norms of the agenda, for medical construction gas piping system with copper pipe standards, China has no product standards, urgently need to develop a special product standards.
Medical gas device with copper pipe special requirements and importance of the decision must pay attention to the construction of this system of standards, combined with the medical center to attract, oxygen system in general and other related technical conditions of the relevant procedures and technical indicators for the clear provisions of the reference to the successful experience of foreign countries and advanced scientific standards to consider the preparation of China's medical gas device with copper pipe standards.
The current medical center suction system, oxygen system general technical conditions YY/T0186 ~ 0187 was released in 1994, has not been able to meet the new requirements of social development and medical and health care undertakings, the need for revision and improvement.
In the building system, the medical gas device pipeline for health care industry, because it is categorized in the equipment and facilities in the supporting, did not form an independent construction acceptance of technical regulations. In the design guidance also lacks a relatively clear targeted provisions.
All these, we can see that the pipeline of the medical system, from the product materials (tubes and fittings) to the design, construction, etc., the need to strengthen the construction of the standard system. Facilities and equipment category, is a hidden system of medical pipeline, more requirements of the various links, the departments of communication, coordination, synchronization of standards and comprehensive supervision and implementation, so as to effectively ensure that China's medical and health care level of improvement, for the benefit of the people.
China's new standards for medical copper pipe how? Medical gas device with copper tube new standard development: to solve the above problem, the new standard has been in the process of development, the new standard for the industry standard YS/Txxxx-xxxx, the name of the "medical gas, vacuum seamless round copper tubes", this standard by the Shanghai on the mass Xin Technology Development Co. Ltd. is responsible for drafting, by the non-ferrous gold M Standardization Technical Committee of Heavy Metals Technical Committee to organize the relevant enterprises and experts to discuss and study, modify, submit for approval, is expected at the end of 2006 through the approval of the implementation.
The newly formulated medical copper pipe standard will put forward clear regulations on the scope of application of medical gas pipes, specifications, pipe cleaning, cleanliness and carbon layer residual children's indicators, testing methods, pipe marking, etc. The preparation of this standard has already been highly valued by the International Copper Association, major design departments, and China's healthcare institutions, which will help the preparation of the specification of the entire medical building and medical equipment system in China, and make China's medical building and medical equipment system more efficient. This will help the whole medical building and medical equipment system standardization in China and make China's medical building and life support system reach the level of advanced countries in Europe and the United States.
