ABSTRACT
Through five experiments, such as "Circle", "square", "side that does not shake", "burning edge", "filter", this paper discussed the effect of different experimental methods of polypropylene fiber liquid filtration membrane particles shedding. The results show that: the particles falling off the edge of the polypropylene fiber Double-sided liquid filtration membrane are very important and must be considered off the evaluation of particle pollution.

A comparison test on the number of puncture coring is conducted using the normal needle and the Huber needle in the injection area of the implantable drug-supplying device separately. The result indicates that the number of coring using the Huber needle is much less than that using the normal needle during the puncturing. So it is suggested to popularize the Huber needle in the drug transfusion of the implantable drug-supplying device.
