1. Prepare a pair of gloves, a pair of scissors, a roll of adhesive tape and a rubber band first.
2. Cut off the finger part of the glove, take out the talcum powder inside, then turn the glove over and poke a hole from the palm of the glove with scissors.
3. Stick the hole in the handle cover with adhesive tape to prevent the hole from being too big.
4. Cut a rubber band, pass the rubber band through the hole in the glove, and tie both ends of the rubber band tightly.
5. At this point, a simple drainage strip is finished.
It should be noted that drainage strips are not suitable for all wounds, and infected wounds and wounds with more bleeding need to be treated according to specific conditions. At the same time, when making and using drainage strips, attention should be paid to hygiene and safety to avoid adverse consequences such as infection.
