AI Technical Summary
Technical Problem
Existing blood processing filters have a slow filtration speed when processing refrigerated blood, are prone to adsorbing white blood cells, and may clog the filter media flow path during storage, resulting in prolonged filtration time and affecting operational efficiency.
Method used
The filter material has a thickness deviation of 0.30 to 0.80 mm. By adjusting the thickness deviation and weight per unit area of the filter material, the unevenness of the blood flow path is ensured, thereby improving the filtration speed.
Benefits of technology
It enables rapid filtration in refrigerated blood processing, reduces blood loss, improves white blood cell removal capacity and blood recovery rate, and enhances operational efficiency.
