Preparation and Inspection for Use

Prior To Initial Use

Before preparation and set-up of this equipment, check all components received against the list of components (see Components section) to verify a complete set. If parts are missing, please notify Welch Allyn. Review the nomenclature, set-up, operations and cleaning sections to become familiar with the equipment.
Specifically inspect:
VideoPath®Proximal Video Camera
Camera Head – for any cracks, dents, scratches and debris. Camera head cable – for any dents, tears or cracks. Light guide connector – for any cracks, dents, scratches and debris.

Light Source

Cabinet – for any dents, scratches or other abnormalities.

Operations

The methods and techniques of endoscopy are well-defined and documented. Endoscopy training seminars and preceptor programs are also in existence world­wide. No attempt is made in this manual to outline any medical procedures. Before beginning a procedure, the physician should be familiar with it and all possible relative contraindications.
1. Plug the VideoPath scope connector port of the light source. The Video Camera connector terminal should fully engage and “click” into place.
2. Activate the Power switch on the front panel. The green Lamp Ignition/Stand-By light will blink for approximately 11 seconds. Once the LED stops blinking, the lamps are ready to be ignited.

4. Press the Lamp Ignition Switch. The lamps will ignite and the Lamp Ignition/ Standby light will go out. The lamps require 11 seconds to warm up. This length of time will be indicated by the center LED of the Picture Brightness Indicator, which blinks until the lamps are fully warmed up, and the system is ready for use.

WARNING: Once lamps have been lit, do not remove the instrument from the light source without turning the main power switch off or putting the lamps on Stand-By by pressing the Lamp Ignition switch. If the Video­Path Proximal Video Camera is removed from the light source, avoid looking directly into the intense light provided by the light source to prevent damage to your eyes.

6. Connect Video Coupler to the eyepiece of the endoscope. Secure coupler/eyepiece connection by tightening the thumbscrew on the coupler.
White Balance Button
8. After white balancing is completed, focus the image by adjusting the focusing ring on the video coupler.
7. White balance the VideoPath Proximal Video Camera by aiming the distal tip of the endo­scope at a white surface at a distance of one to two inches. Momentarly depress the white balance button on the Proximal Video Camera light source connector. Continue aiming the endoscope at the white surface until the image flickers. Once the image flickers, the system has been properly white balanced.

Focusing Ring
9. After the image has been properly focused, it may be necessar y to further adjust the color. The VideoPath Proximal Video Camera has been preset at the factory for optimal picture quality and performance. Monitors can vary and therefore may require some fine tuning. This can be accomplished by using the controls on the monitor.
In some cases, it may be necessary to reduce the moire effect. Moire is a phen­omenon caused by an interference pixel pattern between a fiberscope and a CCD imager, and can be controlled by either slightly defocusing the image or by rotating the video coupler with respect to the eyepiece of the fiberscope.
The system is now functional. Illumination level is controlled automatically by an electronic shuttering system built into the VideoPath.

PC-20 (Model 65180):

Function Control Switches – The function control switches can be used to control

a peripheral video printer. The RS-232 cable must be attached from the light source (Model VLX-20) to the video printer. The controls are as follows:
F - Freezes the image C - Prints the image V - Returns the system to a live video image
By utilizing these switches, the image may be captured and printed for later observation.

Electrosurgery

The user must read and understand all the instructions in the operating manuals sup­plied with the electrosurgical generator and associated accessories. All electrosurgical equipment must be thoroughly inspected prior to use. Only the user can determine if the condition of the electrosurgical generator and accessories is correct and safe for clinical use. The active portion of the electrosurgical accessory should always be clearly visualized before applying electrical energy to the instrument.
Caution: The chassis of the high frequency surgical equipment, if accessi­ble, should be connected to the Equipotentiality Terminal of the VLX-20 Light Source to eliminate the potential of RF voltage potential between the two devices during electrosurgery.
1. The recurring peak voltage of the high frequency surgical equipment used should
not exceed 300 Volts in any mode of operation.
2. Avoid the use of high frequency endoscopically-used accessories in the presence of
flammable anesthetics or explosive gas concentrations.

Cleaning and Disinfection

Immediately after the endoscope is removed from the patient, put the lamps on stand-by by pressing the lamp ignition/standby switch. This will help maximize lamp life. Next, disconnect the video coupler from the eyepiece of the endoscope.
The VideoPath Proximal Video Camera system and all video couplers should be properly cleaned. Any debris should be wiped from the coupler, camera head and cable with a soft lint-free cloth moistened with mild soap and water. An enzymatic detergent may also be used. See the list below for compatible detergents. (Follow the dilution instructions provided by the manufacturer.)
