METHOD FOR MANUFACTURING MEDICAL FILTER

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a medical filter which can stably manufacture a medical filter having excellent pressure resistance for a long period of time.SOLUTION: A method for manufacturing a medical filter includes a process in which a plurality of thermoplastic sheets are welded by sandwiching the plurality of the thermoplastic sheets sandwiching a filter member by facing electrodes 71, 72, and applying a high frequency voltage by a semiconductor type high frequency oscillator 1 to the electrodes 71, 72. In the method for manufacturing a medical filter, a power circuit 100 including the semiconductor type high frequency oscillator 1 outputs a high frequency for a certain period of time.SELECTED DRAWING: Figure 6
