If there are positive deviation, italics, underlined parameters and other clearly required proof materials, please provide corresponding proof materials and indicate the page number in the deviation table, otherwise the bid evaluation committee has the right to deal with negative deviation.

According to the procurement documents, the bidding for this procurement project of Jiangsu Provincial Health and Health Commission will be closed at 9: 30 on May 24th.

Primary medical institutions give priority to purchasing domestic equipment.

In recent years, the frequency of configuring domestic medical equipment in primary medical institutions has been increasing, and it is actually estimated that all 257 medical equipment in Jiangsu Province will be refused to be imported.

Previously, in 20021Hunan Provincial Health and Health Commission subsidized primary health care institutions, 70,585,500 sets of medical equipment such as DR and color Doppler ultrasound were purchased, all of which were made in China.

In addition, in order to support the popularization and application of domestic medical equipment, Guangdong Province has previously issued a document clearly pointing out that medical institutions below the city (county) level are equipped with large-scale medical equipment for the first time, medical institutions above the city (county) level are equipped with a second and above, and medical institutions above the prefecture level are equipped with a third and above, which are clearly used for specific specialties. In principle, domestic equipment should be selected.

In the relevant policy documents of provincial government procurement of imported products, it is constantly emphasized that unless imported products cannot be obtained at home or on reasonable commercial conditions, and it is really necessary to purchase imported products as otherwise stipulated by laws and regulations, domestic medical devices must be given priority.

Recently, the National Health and Family Planning Commission also announced the list of county hospitals that improved the comprehensive capacity of county hospitals under the "Thousand Counties Project". 1233 Primary medical institutions began to sprint to tertiary hospitals. The first is to complete the necessary medical equipment for tertiary hospitals.

Undoubtedly, with the continuous improvement of the graded diagnosis and treatment system, a large number of primary medical institutions are welcoming large-scale equipment replenishment, which also brings huge market space for domestic medical devices and benefits a large number of medical robots!
