  • Patent number: 4045364
    Abstract: A disposable paper with a slightly abrasive surface impregnated with an iodophor and detergent is an excellent germicidal pre-wash in the surgical scrub routine or in any situation where it is important to impede the growth of microorganisms. By using substantially dry impregnated papers the product may be packaged and stored for at least 18 months without undue deterioration. In the presence of undue moisture, the paper degrades too fast for adequate storage.

  • Patent number: 3961629
    Abstract: A surgical laparotomy pad having uniquely useful properties comprises a hydrophilic polyurethane sponge in which the sponge pores have a surfactant coating to accelerate absorption of body fluids into the pores at medically desirable rates, the fluids being retained therein by capillarity to affect removal of the fluids from the body. The sponge is flexible, and substantially free from lint, toxicity, and abrasiveness, making it particularly suitable for use in contact with raw living tissue to absorb blood or fluids, and retain tissues temporarily in position during surgical procedures.
