This invention relates to an endotracheal magnetic tube and safety intubation method. The device is designed with an anti-rust embedded magnetic ring, a powerful magnet is strategically placed under the patient's jaw, and the tube itself is made of high-quality transparent plastic, providing safety and accuracy.

Available in a range of customizable options, the tube can be tailored to fit patients of all age groups. The method involves gently inserting the tube with the magnetic ring into the pharynx, where it is guided by the external magnet into the trachea with zero complications.

By utilizing this non-invasive solution, healthcare professionals can eliminate the risks associated with metal oxidation found in traditional intubation methods. Additionally, the user-friendly design allows the procedure to be performed by individuals at all levels of experience. With its advanced technology and user-friendly features, this invention sets a new standard for safe and effective intubation techniques.

During medical procedures that involve intubation, health care providers usually face issues regarding the proper placement of the endotracheal tube in the esophagus instead of the trachea. This is not a matter of expertise since even by the most experienced doctors could encounter such complications. According to the patient's physical build and medical well-being, the staff's stress levels, the environment where the procedure is happening like a moving ambulance, problems could occur with intubation.

Whether it is pain, discomfort or more serious complications, the need to develop a solution to avoid these existing problems is undeniable. A solution that focuses on minimizing risks and is cost-effective could save lives so the importance of addressing this issue is clear. Here, a safety magnetic intubation device and method is proposed to resolve the health issues that could arise from a failed intubation attempt.

This proposed solution eliminates the need for the presence of experienced personnel and makes the process convenient enough sp that the procedure can be performed by anyone. While existing models require huge funding, this invention is highly reasonable in terms of material and expenses, therefore It can be industrialized easily. A prototype of the device was tested and the results were immaculate, making It a significant step forward and a successful attempt in providing patients with the care they need.

Solution of Problem

In order to tackle the challenges mentioned above, this solution aims to propose a method that can guide the endotracheal tube in a non-invasive and completely safe manner inside the pharynx towards the trachea and move it away from the esophagus.

This flexible endotracheal tube utilizes magnets to increase accuracy when being guided non-invasively and completely safely inside the pharynx towards the trachea. At the tip of the device, there is a magnetic ring, and because of the presence of the head ring, it acquires magnetic properties, interacting with an extremely strong magnet (a standard one obtained from the market) which is placed on the patient's neck.

When the tracheal tube is inserted into the mouth and pharynx, It falls under the influence of the magnetic field of the extremely strong magnet, placed under the patient's lower jaw. Therefore, it is pulled towards the trachea and moves effectively away from the esophagus.

In other words, upon entering the pharynx, the magnetic tracheal tube approaches the trachea-esophagus (laryngopharynx: the last third of the pharynx). However, under the influence of the magnetic field of the super magnet, the magnetic ring at the tip becomes strong and is absorbed by the exterior magnet and enters the trachea with no complications.

It is noteworthy that similar magnetic endotracheal tubes have been introduced for decades, however, a solution that covers all the shortcomings is still needed. This presented device and method ensures safety and has a hundred percent rate success. The material is extremely flexible and non-toxic, so there is no risk of metal oxidation that could cause the patient discomfort or bleeding. The design is customizable in terms of size and capacity, and the comprising elements such as the cuff can be removed or other necessary addendums can be considered.

The difference between this endotracheal tube and prior art is the presence of a magnetic ring at the end, but in terms of classification, size and material, it is not different from common endotracheal tubes, that is, just like the normal endotracheal tube, there are two types, cuffed and non-cuffed, and their material can be simple plastic from polyvinyl chloride or rubber. Fortunately, scientific and medical centers around the world have predetermined these sizes, and children's tracheal tube does not have a fixing cuff or balloon, and the magnetic ring of their magnetic tracheal tube is at the end of the tube. The magnetic chip is placed in order to secure the device. As presented in Table 1, the diameter of the tube can be modified to suit the needs of patients of all sizes and age groups.

The designed magnetic tracheal tube is made of transparent and flexible plastic, and has a magnetic ring embedded in the beginning. This ring is necessarily anti-rust and never comes into contact with moisture and oxygen in the surrounding environment. These properties protect the patient from toxins and prevent metal oxidation. The other important element is the super strong magnet, which is usually made of neodynium and is readily available in the market.

Examples

The invention involves a safe and secure method and device to perform intubation, which was tested with a prototype. In the first step, an extremely strong magnet is attached to the patient's lower jaw near the neck with adhesive tape or other means, which does not take more than 10 seconds. Then the procedures is carried out in turn, chin up back maneuver, and the use of a laryngoscope if necessary and then the use of a magnetic endotracheal tube. After inserting the magnetic endotracheal tube into the mouth, as soon as the end of the magnetic endotracheal tube approaches the part of the larynx (laryngopharynx: two ways of the trachea and esophagus or the last third of the pharynx) It interacts with the magnet. Then the magnet starts to attract the magnetic endotracheal tube to the side of the trachea and pulls it away from the esophagus.

There are a few points to consider when operating this utility model:

1. As soon as the magnetic endotracheal tube approaches the pharynx, the speed of inserting the magnetic endotracheal tube should be reduced to the lowest possible value so that the magnet has enough time to attract the head of the magnetic endotracheal tube.

2. The material of the magnet must be extremely strong

3. In the experiment conducted with the prototype, an extremely strong magnet in the shape of a rectangular cube was used, but if this invention becomes industrialized, I suggest that it is better to use an extremely strong magnet with a special shape, ergonomically designed to complement the neck.

4. The material of the magnet ring in the tracheal tube must be stainless, such as a stainless steel magnet

5. If the patient has trauma to the spinal cord, the jaw thrust maneuver can be used

6. This invention is tested and completely safe.

7. Fix the magnet ring at the end of the magnetic endotracheal tube with money glue on the endotracheal tube so that no oxides are produced.

[Table 1] Contains information regarding the size of the device according to the patient's age group and weight.

Intubation is performed in order to deliver oxygen with a concentration higher than its concentration in the air to the patients. It can also be utilized to deliver other or some volatile gases such as xenon, dinitrogen monoxide, nitric oxide, and hylium which are given to the patient during anesthesia. Moreover, It is used to administer sevoflurane, isoflurane, as desflurane, vipratropium, or epinephrine and atropine, as well as other drugs such as salbutamol and lidocaine bromide. The tracheal tube is used to manage the airway and emergency conditions. The mechanism of intubating patients is similar and It is usually performed on patients who suffer from:

1. Cardiac arrest = atropine and epinephrine + oxygen

2. Distress and respiratory failure = salbutamol + oxygen

3. Head trauma = oxygen

4. Malignant hyperthermia = 111% oxygen + lidocaine

5. Thyroid storm = oxygen

6. Elective intubation patients such as pharyngeal bleeding, tonsils, etc.

7. Patient with lower back = oxygen

8. A patient who is a candidate for surgery without observing the prescribed time = oxygen

Therefore this invention can be industrialized to address the needs of first responders, hospitals, nursing homes, clinics and health care facilities of all kinds.
