, Description:(1) FIELD OF THE INVENTION
The present invention generally relates to the field of visualization of the larynx; visualizing the larynx facilitates endotracheal intubation. This activity helps in revieing the indications received, contraindications & complications (if any) and highlights the role of the interprofessional team in the management of person under the process. The invention, particularly relates to video laryngoscope with oxygen delivery port for apneic oxygenation .

(2) BACKGROUND OF THE INVENTION
A number of different type of Laryngoscopes are available in the prior art. For example, the following literature is provided for their supportive teachings:
Endotracheal intubation is a routinely performed procedure in operation theaters, emergency, triage and Intensive Care Units (ICU). Endotracheal intubation is placement of tube through the glottis into the trachea. This procedure is carried out by using a device called Laryngoscope. Laryngoscope helps in direct visualization of glottis (Conventional Laryngoscopes) or visualization of glottis using camera (Video laryngoscopes). Oxygen saturation frequently falls in critically ill patients during intubation with routinely used conventional laryngoscopes and video laryngoscopes.
Various laryngoscopes are available in the market like McIntosh (Curved blade), Miller (Straight blade) which helps in direct Visualization of glottis. Relatively newer technology called video laryngoscope has a camera and screen to visualize the glottis.
Video-laryngoscopes have been shown to provide an enhanced view of laryngeal structures compared to direct visualization. They have been shown to improve the visualization in difficult laryngoscopy and improve success of intubation. Commercially available video-laryngoscopes in the market are C-MAC (Karl Storz Gmbh & Co., Tuttlingen, Germany), GlideScope (Verathon Medical Inc., Bothell, USA), Airtraq (Prodol Meditec, Vizcaya, Spain), Ambu Pentax-AWS (Ambu A/S, Ballerup, Denmark), McGrath (Aircraft Medical Ltd., Edinburgh, UK) and King Vision laryngoscope (King systems, Noblesville, USA). There are only few video laryngoscope available in the market which has oxygen delivery port like Trueview PCD Video Laryngoscope and APA video laryngoscope with Oxyblade.
Prior art document, US5800344A discloses a laryngoscope having an image sensor assembly mounted thereto for providing video imaging of a patient's airway passage. The laryngoscope includes a distal end having a tip adapted for contact with tissue of an airway passage and an image sensor assembly mounted to a convex surface
However, above mentioned references and many other similar references has one or more of the following shortcomings:
1) Most available video laryngoscopes need introduction of the blade in midline along the tongue, so the Doctors/paramedics have to re-learn the technique of intubation as the device is different from existing traditional laryngoscope
2) Commercially available video laryngoscopes cost ranges from 1lac - 11 lac rupees (1500$ to 15000$) with additional cost of disposable blades
3) Commercially available device uses batteries which also adds to the cost
4) Requires maintenance frequently.
5) Expensive Video laryngoscopes are not easily available for use and for training purposes to the students and paramedics.
6) Most of the laryngoscopes available in the market does not have oxygen delivery port for apneic oxygenation.
The present application addresses the above-mentioned concerns and shortcomings (and other similar concerns/shortcomings) with regard to providing an improved solution with improved properties.
There remains a constant need in society for a continuous flow of new and innovative novelty systems for with improved properties. It is in this context, that the subject invention is useful, not only to provide cheap and easy to use but to provide solution with improved functionalities such as oxygen delivery port for apneic oxygenation.
SUMMARY OF THE INVENTION:
In the view of the foregoing disadvantages inherent in the known types of solutions now present in the prior art, the present invention provides an improved and cost effective video laryngoscope.
As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved cost effective video laryngoscope with oxygen delivery port for apneic oxygenation which has all the advantages of the prior art and none of the disadvantages.

Before describing the detailed embodiments that are in accordance with the present disclosure, it should be observed that the embodiments reside primarily in combinations arrangement of the system according to an embodiment herein and as exemplified in FIG. 1.

Figure 1 illustrates a video laryngoscope with oxygen delivery port for apneic oxygenation into the alveoli in which device is having a handle (1) and curved blade (2) made of medical grade stainless steel for making blade and handle. The device is also having a borescope camera (4) (at tip (3) of laryngoscope blade) , which was designed for visualizing the interior of engines, and works with similar principles to that of the endoscope. In present invention the diameter of borescope is 5mm-8mm and length is minimum 2 meters. The tip of the borescope has multiple light emitting diodes around the waterproof camera which can be connected to a display device for an example even a mobile phone using an application and/or connecter (8). The camera (4) of the borescope is fixed at 40mm from the tip of the laryngoscope for optimal visualization of glottis. There is integrated oxygen channel with oxygen inlet (11) at the base of handle (4) which can be connected to oxygen flowmeter via kink resistant tube (10). During laryngoscopy oxygen is insufflated via oxygen outlet (5) which is present at 4 cm proximal to the tip of laryngoscope to the upper airway and this will help in maintaining oxygen saturation during intubation. There is a knob (7) for increasing or decreasing the intensity of light. There is button (6) for capturing the images of laryngoscopic view for training and documentation.

Functioning of the Device: In one of the embodiments, oxygen tubing is connected to oxygen inlet port and flowmeter and the video laryngoscope cable is connected to display unit/ mobile / tablet/ laptop/ desktop via USB type connecter and/ or an application. Video laryngoscope is inserted from the right side of the mouth and pushing the tongue to the left. The glottis is visualized on the display unit/ mobile/tablet/laptop screen and the tube is passed into the glottis under video image guidance. Real time video recording of the tube passing through the glottis can also be done for documentation and training purposes. After use the laryngoscope blade and handle were washed with soap and water before being wiped with a 70% alcohol swab. The oxygen channel was filled with 2% glutaraldehyde, kept for 20 minutes, drained off and flushed with normal saline for the next use.
Advantages of this Device over the commercial video laryngoscope:
1) The device is designed similar to McIntosh Laryngoscope so that any healthcare provider who is trained in conventional laryngoscopy can use it without any additional training
2) The deep laryngeal oxygen insufflation can be done throughout the procedure of laryngoscopy via integrated oxygen channel and this will prevent decrease in SPO2 level during intubation
3) Oxy- video laryngoscope is 10 times cheaper than commercially available video laryngoscopes with a manufacturing cost between 150$
4) It’s Plug and play device which can be directly connected to mobile phone or laptop via USB
5) With the help of 2 m long cord, the screen of the mobile can be placed conveniently without hindering the procedure.
6) The device can be connected to laptop or big LED screens which is helpful in teaching and training the medical and paramedical staff
7) The device can be beneficial for fast tracking the training of non-anesthesiologists in techniques of intubation in pandemics like COVID-19
8) Does not require battery
9) Device has a waterproof camera which can be easily cleaned like any conventional laryngoscope and can be reused multiple times.
10) It’s a cheap and maintenance free device which can be easily made available in all the hospitals.
