H.6.Investigation summary: when i confirmed the actual product, it seems that it was thinly coated near the tip of the drip needle, and adhesion of chemical liquid was recognized.In addition, as a result of confirming dripping, dropping abnormality was observed in which the grain climbed to the upper side of the drip needle without dropping as it was.Based on the contents of the offer and abnormal dropping of the actual product, during the continuous use of this product by the infusion pump in the drip control mode, this event caused the chemical solution to adhere to the drip needle, the dropping mouth portion became hydrophilic.It was estimated that overflow was due to abnormal drip caused by an increase in grain size per droplet.A dhr was not performed as the lot number is "unknown" for this complaint.
