With the formation of international medical device industry division of labor, labor-intensive or technology content is not \"traditional\" medical device products (such as disposable medical latex gloves, disposable syringes, infusion / transfusion bags, conventional surgical instruments, etc.) since the 1990s have been gradually transferred to the Asian countries (especially to countries with lower labor costs in China, India, Bangladesh, Thailand) production.
R & D and production base in Europe and the United States to become the high-end medical equipment (such as MRI, CT, PET, high-definition X-ray machines and other medical diagnostic instruments and advanced stent implanted medical device products, etc.) . In the foreseeable future, this pattern will not be any major changes.

India:

Rapid development of the medical device industry

In Asia (excluding Japan), China and India has undoubtedly become Asia\\ s two medical device manufacturing and exporting countries. India with China in the production of medical devices originally a large gap in recent years, the central government of India strongly support the national industrial development of pharmaceuticals and medical devices, and export preferential tax rebate policy, so that India\\ s imports of medical devices from 10 years ago the country became the exporting country. Which India\\ s exports of medical products and similar products of China\\ s fierce competition for our products, constitute a considerable threat.

According to reports from the foreign medical device information magazine in 1996, Indian hospitals most of the required medical equipment and medical products are required from overseas input. The United States is India\\ s largest medical products supplier. U.S. medical device industry in the past 10 years, every year to India to send a delegation to promote U.S. production of medical products. Such as 1997, a total of exports to India $ 57 million of medical equipment products, accounting for 40% of the Indian medical device market share. In India, only 90 medical device company, producing one of the few hundreds of medical products (mostly low value-added products). With the steady development of the country\\ s national economy, the middle class continues to expand the medical device industry in India \"taking off\" began in the late 1990s, the medical equipment industry in India began to accelerate the pace of development. By 2006, India has become Asia\\ s fourth largest medical equipment producer and exporter of (only lives in Japan, China and South Korea).

U.S. medical device information site that the medical equipment industry in India will reach 12% ~ 16% annual growth rate in the next five years, and has the potential to surpass South Korea to become the third largest producer of medical devices in Asia. In the past 10 years, China and India, Asia\\ s newly industrialized countries of medical products and sales growth rate is much higher than other Asian countries and regions, because these two countries have large labor force and a large number of middle-income , which constitutes the basis of the rapid development of Sino-Indian medical device industry.

According to foreign media, the Indian medical equipment industry in 2004 total sales of approximately $ 1.26 billion (exports is estimated at about three hundred million U.S. dollars) this year is estimated to be 1.4 billion to $ 1.5 billion, to $ 1.7 billion in 2010 to 19 billion, of which exports will account for one quarter. But compared with Japan and China, the medical device industry in India in terms of output value, the scale of production and exports varieties, the number of still lags behind more.

China:

High-end products to be developed

Nearly according to the U.S., a leading consulting firm DATAMONITOR reported 2006 global hospital supplies and medical equipment market total sales of approximately $ 220 billion (some say has reached $ 260 billion), of which GE, Siemens, Shimadzu, Fujitsu and other international big-time production of high-end medical products account for about 30% share of the international market, the remaining 70% of the medical device market share of many small and medium-sized companies compared to other countries and regions of the world shared. China and India (as well as the emerging Bangladesh and Thailand, etc.) compared to the international medical device market, \"rising star\".

Currently about 60 percent of the U.S. market to 70% of disposable syringes, hypodermic needles, intravenous infusion sets, scalp vein needles, blood transfusion sets, collection bag, catheter, vaginal endoscope, medical gloves and condoms and other latex products, machinery / electric wheelchair, medical products and medical gauze variety of Propylene and practice of dental products, etc. from Asia, especially China and India product-based. Over the past 15 years, Chinese production of medical products meet the ISO9002 standards have been exported to more than 200 countries and regions around the world, including developed countries in Europe and the United States has become of major medical equipment exporting country.

The past, according to domestic media reports, in the first half of this year, total exports of 98 categories of medical device products, the total value of over 1.5 billion U.S. dollars. Estimated that this year exports of medical products worth more than three billion U.S. dollars should not be a problem. Medical Devices in China the largest exporter to the United States, Japan and Germany accounting for about half of China\\ s medical device exports (exports to the three countries), while the bulk of medical products (such as disposable latex gloves, infusion sets, syringes, sterile gauze, the ordinary bandages, conventional surgical instruments, etc.) exports to the countries of Southeast Asia and Africa, and Latin American countries. Most of these products for low value-added products. Price high B ultra-high-resolution X-ray machines and other products in China is still difficult in the international market with similar products in Japan, Germany to compete (in China there are competitive room for the ultra-export markets of the low value of B) .

China although it has become the big countries of Asia and the world medical device manufacturer, but by no means medical equipment production of power. Because the vast majority of China\\ s exports of medical products is the low-end products, so the export value-added is not very high, such joked, according to industry insiders, the United States to China\\ s export of a drug coating vascular stents \"can be arrived too price on China\\ s exports to the U.S. thousands of dozen medical disposable latex gloves. In view of this, China\\ s medical device industry in the international market with the developed countries to compete on the same stage, will take some time.

China should increase the intensity of R & D expenditure and medical equipment and new products development. In particular, should accelerate the development welcomed by the international market permanent implantable cardiovascular disease treatment medical devices (such as pacemakers, vascular stents, as well as more advanced cochlear implant can be used to restore the deaf children of hearing, etc.) to catch up with developed countries in Europe and America advanced level of medical equipment. If the medical device industry in China continues to adhere to the exit routes of the low-end products, most likely in the next few years, the world\\ s medical device market share will shrink.

The other hand, India\\ s medical device industry, although its overall level of backwardness in China, but in recent years with the Indian central government policy to support efforts to increase the country\\ s medical devices that have been made impressive progress. For example, India has spared no effort in the development of ophthalmic medical device products, and has listed the development of a variety of high value-added ophthalmic medical devices and a variety of ophthalmic assistant, product, such as the treatment of glaucoma, advanced slit lamp to dilate medicine, nursing mirror solution (referring to the care of contact lenses syrup), etc., these products are our Yixie industry \"soft underbelly\". It is reported that India\\ s production of ophthalmic medical devices and ophthalmic assistant, product become its strong products exported to overseas market.

All in all, China\\ s medical device industry intends should remain vigilant and cognizant of the gap with developed countries and India and other emerging industrial nations on the product, do not rest on its laurels, fighting for the upper hand in the new round of competition in the international medical device market.

On top of crystal lighting style many people to see dazzling, then how to choose for their own products? I came up with about additions to the crystal lighting should pay attention to.
We must first consider the room structure and decor. Regardless of floor level, interval room, the decoration and distribution of the beam ceilings, interior design style, these problems are to select the factors to be considered and when the device lighting.
Second, we must consider the lighting area. Crystal lighting, indoor lighting effects also play an important role, in general, can be measured according to the diameter of the crystal lamp or light bulb wattage to the illuminated area. But generally crystal lamp as the indoor light source, with some other lights to achieve the proper effect. The designer said that some owners to buy the crystal light, only used on special occasions, usually only room lamps, crystal lamps as the refractive effect of the decoration is very beautiful.
Of course, the most important lighting effects. Light source must be clear, crystal lighting to give full play to its effect, do not use frosted or color bulb, simply accompanied by the ordinary clear and bright bulbs can reach the magnificent effect of crystal light color. The customer may also require the installation of a brightness adjustment button, to better meet the needs of different occasions. The quality of the crystal light pendant link can not be ignored. Crystal lighting, radiant, flawless, safe and cost-effective, in addition to the exterior design of the lamp itself, the selected crystal pendant is also very important. Pendant quality and price of different brands can have great differences, all too easy it would be easy to be fish. In foreign countries, the top crystal lighting and high-end watches, automobiles, is a reasonable investment, collectors. Crystal lighting price of a stock ", there is some imitation of crystal lamps, at first glance shape with little genuine difference, but a closer look at the materials, or lighting effect can not be compared and genuine. Many of the customers is not deep understanding on the pros and cons of crystal lighting, caused by some unscrupulous companies to reap huge profits to deceive customers, its deception range, and some made beads or low-quality imported beads posing level lamp beads, some manufacturers are still Crystal Light at the periphery or attention, coupled with high-quality light beads; but the lights inside the location or a conspicuous place, while the charge.
In addition, some fake crystal chandelier pendant hole if not standard, will be beneficial to the edge, wear, sizes, etc., not only affect the appearance of crystal light, it will crack, crystal chandelier pendant from the ceiling fell, resulting in injury. If the crystal chandelier pendants different shapes and sizes, tall, short, fat and lean in different shapes, which will greatly affect the beautiful appearance of the Crystal Light.

 The power transformer market demand. The power transformer is a labor-intensive products-based and customized production, demand of domestic and international markets in recent years, the rapid development of the popular products. According to statistics, in recent years, China\\ s Taiwan Province, the production of power transformers is expected to grow 50%, Hong Kong will increase by 20 percent, while India will grow by 25 percent.

At present, the demand for global color TV receivers drop has seriously affected the flyback transformer production in Asia. Taiwan, China flyback transformer is now about six manufacturers, while the vast majority have shifted their production bases to the mainland.

    Flyback transformer is a labor-intensive products to be manufactured in Taiwan is more difficult, combined with the LCD monitor not flyback transformer, and its development is ahead of the CRT monitor, mainland enterprises began to produce the LCD monitor with the transformation device. Taiwan flyback transformer product development focus on two aspects:

    First, the development of short-necked CRT with small flyback transformer;

    The second is to enhance the sense of quality, most manufacturers have UL, CSA, VDE, CE, EMI and TCO of class certification as a major goal of improving product quality.

    , Japan flyback transformer has shown signs of excess supply, mainly due to oversupply of Chinese factories of Japanese companies. Enterprise of the flyback transformer with a large number of investment into mainland China, the oversupply situation will continue, and expect this situation will continue for a period of time. Price decline of traditional TV receivers and PC monitors with the flyback transformer, Japanese manufacturers are committed to the production of value-added products, such as projection television flyback transformer.

    In order to avoid price competition, most manufacturers have turned to high-end product market, such as the focus of Japanese media and electronics companies have turned to high-end HDTV receivers and high-resolution monitor flyback transformer. Manufacturers in order to maintain its international competitiveness, is actively using its high-quality technology to develop high-end products.
