Trivia Quiz: What Do You Know About King Vision Video Laryngoscope?

OLED is short for organic light-emitting diode, a display device that sandwiches carbon-based films between two charged electrodes, one a metallic cathode and one a transparent anode, usually being glass. Unlike LCDs, which require backlighting, OLED displays are emissive devices - they emit light rather than modulate transmitted or reflected light. It is beginning to replace LCD technology in handheld devices such as PDAs and cellular phones because the technology is brighter, thinner, faster and lighter than LCDs, uses less power, offers higher contrast and is less expensive to manufacture.

Overmolding is a manufacturing process that essentially combines materials (in this case with different performance characteristics) into one part without adhesives. This allows for a supportive channel where strength is needed and a soft, smooth edge where pliability is required.

Simply turning the Display ON the battery indicator light will come on. The screen displays a static, snowy image because the camera (which is in the blade, not the display) is not attached. A green light indicates adequate battery life. A flashing red light or no image indicates that you should change the batteries before the next case.

King Vision is 510k Exempt.

The King Vision does not contain natural rubber latex. All components and materials have certificates supporting this claim.

If possible, position the patient’s head and neck as you would for any normal intubation, including raising the shoulders and head for obese patients. Scissors the mouth open to gain space to introduce the Blade into the mouth. A lateral approach (like oropharyngeal airway insertion) can be employed with rotation back to the midline once the Blade tip has been advanced to the base of the tongue. In extreme cases, the Blade can be introduced separately followed by Display installation after the blade has been advanced into the posterior pharynx.

The serial number is located on the box label that your device was shipped in. Additionally, the serial number is safely located on a label inside of the battery compartment of the Display underneath the batteries.

You can record an image from the King Vision Display. It requires that you use the King Vision Cable to connect to a video capture device. The Cable is sold separately and is 9’ in length.

Each King Vision disposable blade comes with a factory-applied anti-fog coating on the distal lens. This lens, or window, covers and seals the digital camera and LED light as well. Because this window is treated with a coating, no warm-up is required and the anti-fog feature is effective immediately.

Lubrication of the King Vision Blade and the endotracheal tube is recommended prior to use. With the Standard (non-channeled) Blade, lubricate the distal tip of the blade, taking care to avoid the lens, camera, and light assembly. The endotracheal tube should be lubricated in a normal manner. The Channeled Blade should be similarly lubricated, but its posterior aspect should also be lubricated since it may contact the posterior pharyngeal wall. Lubricate the endotracheal tube and ensure that it slides easily within the blade channel.

Pronounced see-moss, CMOS is a widely used type of semiconductor. Short for complementary metal-oxide-semiconductor. CMOS semiconductors use both NMOS (negative polarity) and PMOS (positive polarity) circuits. Since only one of the circuit types is on at any given time, CMOS chips require less power than chips using just one type of transistor. This makes them particularly attractive for use in battery-powered devices.

The King Vision blades have been engineered to be appropriate for the same patients as a standard Macintosh 3 laryngoscopy blade.

Do not submerge the Display. Use moistened wipes/gauze/swabs, not dripping wet.

No Blade was attached to the Display. The Display can be turned on prior to inserting a blade, but only for a battery life check. Because the camera is in the Blade and there is no Blade attached, the Display cannot provide an image. This results in a snowy screen. Turn off the display and attach a blade before powering on again. This will provide a functional image.

The King Vision consists of two primary components: the display and the blade. The display is used to visualize the airway and guide the intubation process, while the blade is the instrument used to open the patient's mouth and provide a clear view of the airway. The battery is not a primary component of the King Vision, as it is necessary for powering the device but does not directly contribute to its functionality.

While lithium batteries generally last longer than standard alkaline batteries, the power curve with lithium falls off quickly. This rapid loss of power shortens the user’s time to respond at the end of the batteries’ life once the King Vision battery indicator light begins to flash red. The power stored in alkaline batteries is reduced more gradually, allowing sufficient time to finish a typical procedure prior to replacing the batteries. Replace the batteries prior to the next use.

The King Vision Display is covered in the warranty. Warranty coverage begins from the date of purchase and lasts for one year.

While the cover can't be easily replaced, it is covered in the warranty program. Follow the warranty procedure and your sales representative will provide you with a loaner device while we repair or replace your video-out port cover.

The King Vision is a Class 1 device (rigid laryngoscope- Product Code CCW)

The King Vision video laryngoscope blade differs from a direct laryngoscope blade in several key ways. Firstly, the King Vision uses a digital camera to view the vocal cords indirectly by looking around the corner under the base of the tongue. This indirect view allows for a curved blade that approximates typical anatomy, resulting in less manipulation of soft tissue compared to direct laryngoscopy. However, minor manipulation or lifting of soft tissue may still be necessary and acceptable. Additionally, although not its intended function, the King Vision Blade meets the lifting strength requirements for direct view laryngoscope blades according to the ISO 7376 standard. Therefore, all of the above statements are true.

Under continuous use, three AAA batteries should last over 90 minutes. Your actual experience may vary based on a number of factors including, but not limited to; the age of the batteries, a number of on/off cycles, length of procedures, use of video output. Follow the battery manufacturer’s guidance on specific battery use.

The design of the King Vision blade allows either technique to be used successfully. We recommend starting with the Blade tip in the vallecula (Mac approach) to avoid going too deep, but the tip can also be placed under the epiglottis (Miller approach). Direct clinicians to the IFU for more information.

The King Vision is not sterile. However, the Display and Blades are packaged and delivered clean and ready to use.

While there is no replacement for the rubber gasket, it is covered under the warranty program. If a display’s gasket is in disrepair, follow the warranty procedure. A sales representative may provide a loaner device if necessary while we repair your gasket.

The King Vision comes with three alkaline batteries, factory packaged. Once installed, the portable, high density, closed-cell foam display carrying case has a storage location for extra batteries.

King Vision uses a sophisticated power management system that is designed to conserve power. It will automatically power off when the Blade is removed from the Display. With the Blade attached, it will power off after 60 seconds once placed on a non-moving surface due to an integral motion sensor. After power-on of the Display only (i.e., to check battery status), power-off occurs after 20 seconds.

You can disinfect the Display if it becomes soiled, but do not sterilize it. The Blades are single patient use and cannot be cleaned or sterilized. Refer to the IFU for instructions on how to clean and/or disinfect the Display.

While not required, it is often advantageous to preload the endotracheal tube into the guiding channel of the Blade. Alternatively, the user may elect to place the lubricated endotracheal tube in the channel after the Blade is inserted into the patient’s mouth.

Although the video out on the King Vision Display appears to be a mini-USB connection, it is not a standard fitting in that only video out is permitted. Other cables, though they may appear to fit the small USB port, may damage the display or your monitor. This action also voids the warranty. The cable connects to the monitor using a standard RCA connector.

The Channeled Blade is designed to guide the endotracheal tube to the vocal cords. The channeled portion of the Blade is comprised of a combination of a rigid plastic forming the support of the channel and a soft, over-molded portion comprising the outer edge and external lower portion of the channel. This soft, outer edge facilitates easy removal of the endotracheal tube from the Blade after placement and provides a soft posterior blade surface during insertion. No other channeled video laryngoscope has this feature.
