Fact sheet for healthcare providers and patients:

 As an example for a medical gown article made with the HeiQ Viroblock NPJ03 treated textile:

  • Textiles provide a large hosting surface area for bacteria and viruses, benefiting their carryover
  • Viruses and bacteria can remain active on textile surfaces from days to months 1)
  • Human coronavirus (SARS-CoV) can persist for up to 2 days on surgical gowns at room temperature 2)
  • This gown is treated with HeiQ Viroblock NPJ03 actively inhibit viruses and kill bacteria upon contact helping to minimize the potential for re-transmission of pathogens from the gown
  • Strong antiviral and antibacterial effect against enveloped viruses (incl. Coronavirus 229E) and bacteria
  • Residual virus infectivity tested according to a modified ISO 20743 method (Sendai virus), rapid antiviral effect demonstrated within 2-5 minutes (99.99% reduction)
  • Hypoallergenic, provides self-sanitizing and germ resistant surface
  • Patent pending antiviral and antibacterial technology
  • Lasts at least 20 gentle washes at 85°F
  • Wear a gown that is appropriate to the task, to protect skin and prevent soiling or contamination of clothing during procedures and patient-care activities when contact with blood, body fluids, secretions, or excretions is anticipated
  • Wear a gown for direct patient contact if the patient has uncontained secretions or excretions
  • Remove gown and perform hand hygiene before leaving the patient’s environment
  • Routine donning of gowns upon entrance into a high risk unit (e.g., ICU, NICU, HSCT unit) is not indicated
  • Don gown upon entry into the room or cubicle. Remove gown and observe hand hygiene before leaving the patient-care environment
  • After gown removal, ensure that clothing and skin do not contact potentially contaminated environmental surfaces that could result in possible transfer of microorganism to other patients or environmental surfaces.
