H.6.Investigation summary: connected the injector part of the actual product (515573-zat, which was discontinued due to clogging) to the spike set (faceal connector luer lock), and confirmed that the liquid flowed.In addition, when the lure connector of the actual product (515573-zat that was blocked and was discontinued) was connected to the mixed injection part upstream of the drip tube of the chemosafe infusion set, liquid flowed out of the end of the chemo safe infusion set without any problems.The cause could not be identified because there was no abnormality such as clogging, and the event was not reproduced.This event is presumed to have occurred due to incomplete connection.In order to prevent the occurrence of poor fluid flow, as part of continuous quality improvement, we changed the shape of the terminal luer connector to the luer lock integrated type (fixed lock) so that the connection can be made more reliably.A review of the device history record revealed no irregularities during the manufacture of the reported lot.H3 other text : see section h.10.
