The invention relates to a medical supply, in particular to an
intramuscular injection plaster, namely a wound protector for closing small needle holes after treatments such as infusion,
intramuscular injection and
blood collection in clinical medical units. The
intramuscular injection plaster is formed by sequentially stacking a PU (
polyurethane) film layer, a foam layer and a release paper layer. The PU film is at the top, the foam is in the middle, and the release paper is at the bottom. The intramuscular injection plaster is applicable to assisted coagulation and aseptic closure for small
skin defects such as needle holes in
clinical diagnosis and treatment, potential infections caused by the
exposure of small wounds left after clinical
blood collection, injection and the like are avoided, and
wound healing is assisted. Iatrogenic environmental
pollution is less, the iatrogenic environmental
pollution caused by patients discarding the used hemostatic materials such as
cotton balls and cotton swabs can be avoided, and disinfection cost is lowered.
