Title:
ポンプ給送濾過血液処理装置及び方法
Document Type and Number:
Japanese Patent JP4623767
Kind Code:
B2
Abstract:
Automated filtration of whole blood or blood components is accomplished in a manner that ensures consistent flow or pressure characteristics through the filter. A feedback circuit monitors pressure in the vicinity of the filter inlet and controls operation of a fluid pump that sends one or more unfiltered blood components into the filter. Using this arrangement, a variety of parameters relating to filtration efficacy can be precisely controlled, including flow rate, flow pressure, and average pressure over a predetermined volume. The system may provide an alarm or automatic cut-off in the event a maximum value of one of the parameters is reached or exceeded. The system is also capable of serially filtering multiple blood products through the single filter and accommodating different flow or pressure characteristics associated with each such product.
