We generally use small and medium-sized specifications to wrap the high-frequency electric knife in the inner packaging bag, that is, insert the electric knife into the inner packaging bag of the paste towel, the blade is exposed from the corner, wrap and rotate the handle of the electric knife, so that the plastic bag is flat wrapped in the electric knife, and cut a piece of silk thread to tie the end. The rechargeable electric drill is wrapped in a large plastic bag, and its drill bit and rotating shaft are threaded out of the bag. Because the plastic bag is thin, soft and transparent, the switch of the electric knife and the electric drill is clearly visible, which does not affect the operation of the operator, but also protects the electric knife and the electric drill from being stained by blood, so that the electric knife and the electric drill are clean and convenient for nursing work.
