orlvision
accepts no liability for diagnoses and interpretations of findings made with the aid of medical
products acquired from
orlvision.
The acquisition of medical expertise and its diagnostic and thera-
peutic consequences are solely the responsibility of the user of the medical product.
Before each use, test the direction of movement of the bounce unit by operating the adjustment lever
to avoid incorrect bounce direction. Check a test image to verify colour fidelity.
We recommend the use of a lubricant on the shaft before inserting the shaft into the nasal cavity to be
examined.
4.3
Application
The flexible Video Rhino Laryngoscopes from
orlvision
GmbH (hereinafter referred to as orlvision)
are high-quality medical products. They are used for endoscopic examinations in human ear, nose
and throat medicine. The flexible Video Rhino Laryngoscopes can be used to examine the nasophar-
ynx. The image of the examination region can be displayed on a high-resolution screen and saved.
The RS1/RX1 laryngoscope is intended exclusively for use in clinics and may only be used by person-
nel specially trained in handling endoscopes!
Perform a white balance before each use (see section 7.1). Proceed with cleaning and disinfection as
described in these operating instructions.

How it works
At the distal end of the Video Rhino Laryngoscope is the exit of a light guide that illuminates the obser-
vation region. An attached lens enables imaging at a viewing angle of 90 °. The image thus captured
is recorded by a video camera, converted into an electrical signal and made available at the output of
the Video Rhino Laryngoscope as an analogue video signal for display on a monitor.
The light for illuminating the observation region is obtained from a cold light source. The distal end of
the insertion tube can be angled in a range of
130 ° by operating the adjustment lever.
The supply of electrical energy is ensured by a medical power supply unit included in the delivery.
