Abstract:Objective To develop a kind of waterproof sterilization indicator card to solve the problem of uneven discoloration occurred in the sterilization process of common indicator cards. Methods A kind of waterproof and protective film was designed and coated on the surface of the common sterilization indicator cards. Then the waterproof effect experiment was conducted by packing ordinary sterilization indicator cards and waterproof indicator cards into gauze bags and metal bags to sterilize them (132 ℃, 3 min). Then the numbers of qualified cards and unqualified cards were recorded. Results There were significant differences between waterproof cards and ordinary cards on the numbers of qualified cards and unqualified cards (P<0.05), which indicated that the waterproof property and discoloration effect of waterproof cards were better than those of ordinary cards. Conclusion The waterproof effect of the waterproof sterilization indicator card with normal indicator discoloration performance is good .
