SafeGuard-BR-System - Closed intubation systems with improved respiratory tract access for examination equipment

Ref.-No. 6067

Keywords: acute respiratory distress syndrome (ARDS), Bronchoscopy, respiratory system

Many patients underlying artificial respiration – especially COVID-19 patients – suffer acute respiratory distress syndrome (ARDS), the treatment of which requires pressure-controlled respiration with positive end-expiratory pressure (PEEP) and humidified, temperature-controlled ventilation air.

During intensive-care treatment, bronchoscopy with bronchoalveolar lavage (BAL) is regularly used during acute treatment and sample collection. During emergency situations, such as bleeding and airway obstruction, bronchoscopy must be performed quickly. The closed respiration system is opened and the necessary examination performed, releasing aerosols and droplets into the ambient atmosphere. This involves a significant exposure risk in cases of infectious diseases (SARS-CoV-2, MERS, influenza, tuberculosis etc.) to medical health personnel directly involved.

Competitive Advantages

  • Allows hygienic work during bronchoscopies
  • Protects health personnel
  • Avoids contamination of the environment
  • Compatible with other surgical devices

Commercial Opportunities

This invention provides a sealed respiration system that allows hygienic, protected performance of intensive-care examinations without releasing aerosol particles or droplets into the ambient atmosphere.

Current Status

Initial data on model tests and illustrative films on practicability are available.
