More about us

Since 1912

Originally founded in 1912 as a family-owned manufacturer of surgical instruments Carl Reiner GmbH has known a long tradition in the development and manufacturing of cutting-edge surgical instruments. Especially during the early 20th century, which saw great advances in ENT medicine in Europe (and in Vienna in particular), Carl Reiner GmbH was at the forefront of new developments.

It was no coincidence, therefore, that professor of otolaryngology Oskar Kleinsasser (1929 – 2001), a great pioneer in the development of microlaryngoscopy in the early 1960s, would turn to Carl Reiner GmbH for the first prototypes of the Kleinsasser laryngoscopes. Still today these laryngoscopes bear his name and are widely used. This is but one example of many developments Carl Reiner GmbH was part of in those days.

It wasn’t until the late 1980s that Carl Reiner GmbH would gradually shift its focus towards a particular form of mechanical lung ventilation, called ‘jet ventilation’. The close cooperation with the University Hospital of Vienna, and Dr. Alexander Aloy in particular, demonstrated that there was a real need for a ventilator designed to cater to the specific needs of upper airway surgery.

In 1989 close cooperation with Dr. Forrest M. Bird (1921 – 2015), who had started to develop his own mechanical lung ventilators already in the 1950s, resulted in the first jet ventilator equipped with dedicated jet instruments, called ‘Bronchtron 1G’.

Its modern-day successor, an electronically-controlled jet ventilator with a 10.4” touchscreen first saw the light of day in 2006. Since then the TwinStreamTM jet ventilator has been installed in 40+ countries worldwide and has become an invaluable asset in numerous university hospitals. Needless to say a wide range of carefully crafted jet instruments such as jet laryngoscopes and jet bronchoscopes still set this device apart from any other ventilator.

Jet instruments

How Do They Work?

Jet instruments provide optimal accessibility and visibility of the surgical site, while safely ventilating the patient. When using a Jet Laryngoscope or Jet Bronchoscope there is no need for an endotracheal tube or jet catheter. The integrated channels guarantee optimal patient safety and allow full control of pressures and gas concentrations in the airway.

What is S-HFJVTM?

'Double' jet ventilation provides the best of both worlds

Superimposed High-Frequency Jet Ventilation (S-HFJVTM) combines a pressure-controlled ventilation at normal frequency, e.g. 12/min, with High-Frequency Jet Ventilation (HFJV) at e.g. 600/min. The high frequency is ‘superimposed’ over the normal frequency.

Why use S-HFJVTM?

'Double' jet ventilation or S-HFJVTM allows you to not only optimise oxygenation, but at the same time effectively eliminate CO2.

  • Completely open airway
  • Automatic limitation of airway pressures
  • Monitoring of gas concentrations (FiO2 , EtCO2 )
  • No need to rush the procedure due to rising CO2 levels
  • Allows for a better patient outcome

Supraglottic 'tubeless' ventilation

With a jet laryngoscope you don't need an endotracheal tube or jet catheter anymore. The complete integration of ventilation and airway monitoring into the jet endoscope is an unparalleled advantage in shared airway surgery. 

  • Complete surgical visibility
  • Optimal surgical accessibility
  • Optimal oxygenation
  • Effective CO2 elimination
  • Laser Safe Mode (LSM)
  • Pressure and gas monitoring
