Description

Tongue advancement device and method of use thereof

The present invention generally refers to a medical tool, and more particularly to a breathing airway space that can easily open the mouth and throat after the tongue is mentioned, so that it is optimal to provide an early advancement of the tongue in the tracheal intubation environment. And its use.

Endotracheal intubation is the insertion of the endotracheal tube into the trachea of the patient through the mouth or nasal cavity to perform artificial respiration or pressurized oxygen to maintain airway patency.

Endotracheal intubation plays an important role in the treatment of respiratory tract. However, when intubation, it is often due to obesity, structural abnormalities and improper use of the patient, which increases the difficulty of intubation, even The patient's throat and airway cause significant damage, so it is extremely important to make the tracheal intubation operation simple.

Current tracheal intubation is commonly performed with a Laryngoscope and a Videolaryngoscope. The method of opening the airway is to place the front end as far as possible at the base of the tongue, then push the tongue forward and push it up to open the temporomandibular jaw. Close the TMJ to open the throat space. Usually, these laryngoscopes can open the respiratory tract. However, there are still missing. For example, in patients with small chin, obesity and big tongue, the length and curvature of the laryngoscope are often too deep in the narrow oral space. In addition, the laryngoscope itself is limited by its thickness and volume. When it is extended into the cavity, it will move the tongue inward, causing the position of the throat to change, the space is reduced, and then try to open the throat. At this time, there are often techniques. Difficulties and limitations in vision, even if experienced physicians often complete intubation at a rate of less than 90%, multiple attempts are required to achieve a success rate of around 95%, and the success rate of novices is even lower. When the intubation process is not smooth, in addition to causing damage to the internal tissues of the mouth, it also endangers the safety of the patient's life, especially in the case of intubation failure.

In addition, endotracheal intubation is also assisted by intubation using a videostylet (Videostylet) and a fiberoptic scope. However, the visible rigid tube mirror directly places the lens in the middle of the mouth without opening the throat, so only the local closeness can be seen, and the tongue above it tends to move it together into the throat, changing it. The normal structure of the throat, and because it does not open the space in front, the lens is often affected by saliva, resulting in blurred images, it is easy to lose the orientation and direction, so the success rate is not high; and the fiber optic bronchoscope is large The use process is quite time-consuming, expensive, easy to damage, and long-term learning. It is usually only used when it is difficult to intubate, and often requires multiple attempts to succeed. Therefore, by both (visible tube and fiberoptic bronchoscope) for tracheal intubation, there are also obvious missing, and there is a need to improve. Therefore, how to improve the problems of the existing tracheal intubation operation should be an important direction for the industry to solve and overcome.

The key problem in the operation of the auxiliary device required for the above-mentioned endotracheal intubation is that the tongue cannot be smoothly opened to open the throat. The prior art has a lack of effective design and double-effect combination with the tongue and the forward tongue. effect. However, due to the operation of lifting the tongue and moving the tongue, it is necessary to further consider the design of the force-applying device of the tongue-lifting device and the moderate micro-deformation consideration after the force application, so that the advancement device on the tongue can achieve its intended effect. Therefore, how to impart an advancement on the tongue while facilitating the operation of combining the upper tongue and the forward tongue is the focus of the technical feature design of the present invention.
