2019 Year 12 Since January, a number of new infectious diseases caused by new coronavirus infection have been found in Wuhan City, Hubei Province. With the rapid spread of the epidemic, patients with such infectious diseases have been found in other parts of China and abroad. In order to prevent and control the epidemic, the whole country has adopted isolation, restricted personnel from going out, the situation of blood collection and supply is grim, and blood collection has been greatly affected. In addition to the urgent need for blood treatment for trauma, blood diseases, maternal complications, and patients undergoing major surgery, patients with new coronary pneumonia also need blood treatment.

Under the careful organization and leadership of Professor Wang Quanli, chairman of the China Blood Transfusion Medical Equipment Technical Committee, from many blood centers and hospital blood transfusion departments14Experts participated in and completed the preparation of the standard of "preparation and quality control of leukocyte-depleted mixed concentrated platelets. During the preparation of the standard, the opinions of many experts in the field of blood transfusion were widely listened to, and many experts put forward constructive opinions on the standard.2019 Year4 Month13Day from all over the country30 A number of blood transfusion industry experts and scholars gathered at the Nanjing Red Cross Blood Center to participate in the review and approval meeting of the standard. The participating experts had a lively discussion on the standard, which laid a solid foundation for the finalization of the standard.2020Year2Month13Japan China Medical Equipment Association issued the standard of "preparation and quality control of mixed concentrated platelets to white blood cells.

The introduction of the standard helps to standardize the process of preparation and quality control of leukocyte-depleted concentrated platelets in China,ABOThe efficacy and safety of leukocyte-free mixed concentrated platelets prepared by leukocyte-free filtration after collection of the same type of concentrated platelets can be comparable to that of apheresis platelets, thus achieving better utilization of blood resources and ensuring the supply of clinical platelets.

In the new crown virus epidemic period, blood tension, the use of this standard, can make full use of the precious platelets in whole blood, the introduction of the standard to promote the effective utilization of blood resources in China to provide important technical support.

As the first drafting unit of the standard, Nanjing Shuangwei Biology has been paying close attention to the development of blood transfusion industry at home and abroad, and has been committed to the research on the preparation and application of leukocyte-depleted mixed concentrated platelets. Over the years, it has continuously refined the performance of platelet leukocyte-depleted filter products required for the preparation of leukocyte-depleted mixed concentrated platelets, maintained close communication with clinical practice, and actively responded to the call of the state to play a supporting role in technological innovation of enterprises and industries. Ms. Hu Zhengfang, the general technical consultant, actively participated in the drafting and revision of the standard, and was responsible for the summary and sorting of the standard solicitation opinions and the drafting of the standard preparation instructions. It is believed that with the joint efforts of the national blood transfusion community, high-quality whole blood platelet separation and concentration can be widely used in clinical practice.

God bless China! Come on, Wuhan! Come on China!
