Germlyser® ENT

Point-of-use hollow fibre membrane filter for ENT treatments

The Germlyser® ENT is a CE-marked, inline sterile grade filter for use in CE-marked ENT units. The filter is installed between ENT handle and the nozzle to prevent bacterial nosocomial infectious diseases caused by Pseudomonas aeruginosa, Legionella pneumophila, Stenotrophomonas maltophilia or Staphylococcus aureus among immunosuppressed and immunocompromised patients.

  • Sterile filtration, 7 log units (Brevundimonas diminuta)
  • Operating time of 4 weeks
  • Sterile CE-marked inline sterile grade filter for use in CE-marked ENT units

Germlyser® ENT

During the caloric check of the equilibrium functions of the ear, water is flushed into the ear to trigger a nystagmus. The Germlyser® ENT is used to prevent bacterial infections caused by Pseudomonas aeruginosa, Stenotrophomonas maltophilia and Staphylococcus aureus among immunosuppressed and immunocompromised patients during this examination.

The operating time of the filter is 4 weeks. Sterile closing cones can be used to ensure hygienic protection during downtimes. The filter can be environmentally put to disposal after usage (plastic collection service).

Germlyser® ENT delivers a constant high flow rate of bacteria-free water over its entire operating time an effectively protects against waterborne bacteria.

Prevention through water hygiene

The flushing of the ear canal requires the use of water that is free from pathogenic bacteria such as Pseudomonas aeruginosa, Legionella pneumophila, Stenotrophomonas maltophilia or Staphylococcus aureus.

However, the narrow water feed lines of ENT treatment equipment can cause heating of the water, and coupled with long stagnation times (overnight or at weekends) creates an ideal environment for bacteria proliferation.

Decontamination of equipment by means of thermal or chemical disinfection can be very difficult due to the build up of biofilm on the inner walls of water-lines or potential damage to the thin plastic walls of the pipes.

Membrane filtration of tap water is an effective method of delivering bacteria free water and protecting patients from the threat of infection.
