Description

[Technical field]

[0001] The present invention relates to the technical field of medical equipment, specifically to a device that converts oral to nasotracheal intubation. [Background technology]

[0002] Tracheal intubation is an important measure to ensure airway patency, improve ventilation, and maintain oxygenation in critically ill patients, and includes two methods: oral tracheal intubation and nasotracheal intubation.

[0003] Oral tracheal intubation is simple and quick to operate, has a short treatment time, and has a high success rate of intubation. It is often used in the first aid of severe acute patients and can quickly improve the ventilation of patients. However, it has a very significant disadvantage in the subsequent long-term treatment.

[0004] 1. It adversely affects the physiological functions of the patient's oral cavity and related structures. On the one hand, long-term oral tracheal intubation may cause the patient to suffer from complications such as sore throat, hoarseness, bloody sputum, maxillary mucosa damage, tongue swelling due to pressure, and oral venous return disorder. On the other hand, long-term passive "mouth open and holding the tube" posture may cause temporary or permanent dislocation of the mandibular joint.

[0005] 2. It has a negative effect on the oral hygiene of patients. The fixation of oral intubation is affected by many factors, including the integrity of teeth, occlusal function, cough reflex, and state of consciousness. For example, elderly patients have physiological tooth loss, loose gums, and weak occlusion, which makes oral intubation lose a relatively stable fixed point and very easy to escape. In addition, young patients have a strong cough reflex and strong occlusion, but they have poor tolerance to intubation, and are restless and often cough up the intubation, which causes the intubation to be stopped. Or they bite the tube, which causes the intubation to collapse, making it difficult to intubate.

[0006] 3. Oral intubation has a large degree of mobility and is poorly tolerated. Oral intubation is delivered through the oral cavity and can move left and right within the oral cavity, and can also move up and down with the swallowing action, which causes a large irritation to the pharynx and posterior pharyngeal wall, leading to discomfort such as nausea and vomiting, and therefore poor tolerance.

[0007] For this reason, in clinical practice, the duration of orotracheal intubation is often 3-7 days, not exceeding a maximum of 14 days. In patients whose disease course is expected to require a long-term airway passage, conversion to non-invasive nasotracheal intubation or the performance of an invasive temporary tracheotomy should be considered immediately.

[0008] Nasotracheal intubation has the advantages of being easier to tolerate, easier to fix, easier to care for, and longer indwelling time. 1. Unlike oral intubation, nasotracheal intubation is entered through the nasal cavity, so it is less mobile and easier to fix, reducing the risk of detubation and making oral care and oral feeding more convenient for patients. 2. Nasotracheal intubation causes less irritation to the throat and has a lower incidence of gag reflex, making it easier for patients to tolerate, and is favorable for reducing the use of sedatives and analgesics in clinical practice. In clinical practice, some patients do not need to use sedatives and analgesics during the period when nasotracheal intubation is used. 3. Patients who undergo early nasotracheal intubation have a significantly shorter time of relying on mechanical ventilation than those who undergo oral intubation, and some patients have avoided the implementation of tracheotomy. And the patient's family and some patients who are conscious are more receptive to nasotracheal intubation.

[0009] Therefore, in emergency, critical patients who use oral tracheal intubation to open the airway must be changed to nasotracheal intubation after being evaluated by a doctor. Because the oral and nasal passages are not connected, in current clinical operations, the oral tracheal intubation must first be thoroughly removed, and then the tube is inserted again through the nose using methods such as blind intubation, laryngoscope assistance, bronchofiberscope assistance, LED light assistance, and ultrasound assistance. This process has high difficulty and risk. 1. From a physiological point of view, the airway mucosa that has been orally intubated once often has a certain degree of congestion and edema, and the anatomical structure may not be clear even under the assistance of a visual laryngoscope. 2. When oral tracheal intubation is removed in critical patients, a lot of subglottic sputum or airway secretions will overflow, and the visibility of the field of view near the glottis will be reduced. 3. When oral tracheal intubation is removed, it is similar to completely cutting off the respiratory support for a while, and the patient may experience a rapid drop in oxygen saturation or oxygenation. 4. If sufficient amounts of anesthetics or muscle relaxants are used, on the one hand, they can inhibit the patient's spontaneous breathing, and on the other hand, they can reduce body temperature and blood pressure, making it impossible to maintain vital signs and potentially threatening to life.

[0010] Therefore, intubated patients can be assisted in tube exchange, achieve a "tight connection" throughout the entire tube exchange process, access respiratory support equipment at any time, prevent repeated intubation and reduce airway damage, require easy-to-operate and quick auxiliary tools, improve the success rate of tube exchange, reduce the risks during tube exchange, and ultimately achieve the purpose of improving patient prognosis. Summary of the Invention

[0011] The object of the present invention is to overcome the above problems and provide a device that changes oral tracheal intubation to nasotracheal intubation. To achieve the above object, the present invention uses the following technical means.

[0012] A device for converting oral tracheal intubation including a semicircular tube and a guide tube into nasotracheal intubation, in which an opening is provided on the side of the semicircular tube through which the guide tube or the tracheal intubation tube can be inserted, the diameter of the guide tube is smaller than the diameter of the semicircular tube, and magnetic attraction parts are provided on the inner wall of the semicircular tube and at a position near the end of the side wall of the guide tube, which are combined with each other.

[0013] As an improvement, the openings extend to both ends of the semi-circular tube, so that the semi-circular tube assumes a U-shape without being subjected to the action of external forces.

[0014] As an improvement, the guide tube is provided with a scale indicating the insertion depth.

[0015] As an improvement, the scale reading of the guide tube is 5-65 cm, and the length of the guide tube is 65-75 cm.

[0016] As an improvement, the magnetic attraction portion is provided at a position near the middle of the inner wall of the semi-annular tube.

[0017] The advantages of the present invention are as follows:

[0018] The present invention uses a method of matching a semicircular tube with a guide tube to assist in guiding tracheal intubation, which can effectively reduce the difficulty of tube exchange and improve the success rate of tube exchange.

[0019] The present invention can minimize the risk of sudden changes in the patient's vital signs and life-threatening risks caused by the need to take a break from respiratory support during the tube exchange process of "changing from oral tracheal intubation to nasotracheal intubation" and use of anesthetics, muscle relaxants, etc., and can also greatly improve the success rate of one tube exchange and avoid repeated intubation causing further damage to the airway. At the same time, the device is easy to operate and learn, and can be popularized in flagship hospitals to realize its important clinical application value. [Brief description of the drawings]

[0021] In order to make the objectives, technical means and advantages of the embodiments of the present invention clearer, the technical means in the embodiments of the present invention will be described clearly and completely below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of the embodiments. Generally, the assemblies of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

These are merely for the purpose of easily explaining and simplifying the present invention, and do not indicate or imply that the devices or elements shown have a specific orientation, or must be configured or operated in a specific orientation. Thus, they should not be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are merely for the purpose of distinction and explanation, and should not be understood as indicating or implying relative importance.

[0023] Additionally, terms such as "horizontal", "vertical", "suspended" and the like do not indicate that a member is required to be absolutely horizontal or suspended, but may be slightly tilted. For example, "horizontal" only means that the direction is more horizontal than "vertical", and does not indicate that the structure is necessarily perfectly horizontal, but may be slightly tilted.

[0024] In describing embodiments of the present invention, "plurality" means at least two.

[0025] In the description of the embodiments of the present invention, unless otherwise clearly specified or limited, the terms "installation", "mounting", "connection" and "connection" should be broadly understood. For example, they may be fixedly connected, detachably connected, or integrally connected. They may be mechanically connected or electrically connected. They may be directly connected, indirectly connected via an intermediate member, or the insides of the two elements may be in communication. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific situation.

[0026] Example 1 In this embodiment, a device is disclosed that changes oral tracheal intubation to nasotracheal intubation, including a semicircular tube 1 and a guide tube 2. An opening 11 is provided on the side of the semicircular tube 1, through which the guide tube 2 or the tracheal intubation tube is inserted, and the opening 11 extends to both ends of the semicircular tube 1, so that the semicircular tube 1 assumes a U-shape without being subjected to the action of external force.

[0027] The diameter of the guide pipe 2 is smaller than that of the semi-annular pipe 1, and a magnetic attraction portion 3 is provided on the inner wall of the semi-annular pipe 1 and at a position close to the end of the side wall of the guide pipe 2. The magnetic attraction portion 3 is provided on the inner wall of the semi-annular pipe 1 at a position close to the middle portion.

[0028] The guide tube 2 is provided with a scale 4 indicating the depth of insertion. The scale 4 indicates 5 to 65 cm, and the length of the guide tube 2 is 65 to 75 cm.

[0029] The method of using the present invention will now be described with reference to the drawings.

[0030] As shown in Figure 5, after patients receive emergency first aid, they generally use oral tracheal intubation, and some time after first aid is completed, the doctor evaluates that oral tracheal intubation needs to be converted to nasotracheal intubation.

[0031] The specific operation steps are as follows:

[0032] S1. First, the gas in the balloon of the oral tracheal intubation A is released, and then the semicircular tube 1 is covered and attached to the outer edge of the oral tracheal intubation A as shown in Figures 6 and 7, and then lightly inserted into the airway. Because the oral tracheal intubation A exists, the semicircular tube 1 can be guided from the oral tracheal intubation and smoothly inserted into the airway.

[0033] S2. After the semicircular tube 1 was inserted to an appropriate depth (approximately 20-22 cm), the oral tracheal intubation tube A was removed as shown in Figure 8. In this case, the semicircular tube 1 is placed in the airway, so if necessary for the patient's condition, the semicircular tube 1 can be used to connect to respiratory support equipment to maintain the patient's oxygenation.

[0034] S3. As shown in Figure 9 and Figure 10, the guide tube 2 is sent to the glottis position through the nasal passage, and in this case, the magnetic attraction part 3 of the semi-circular tube 1 and the guide tube 2 are attracted to each other near the glottis, so that the semi-circular tube 1 and the guide tube 2 are connected, and then the direction in which the guide tube 2 will soon slide into the airway is precisely positioned, and then, with a little force, the guide tube 2 can slide into the airway. The scale 4 determines whether the guide tube reaches the appropriate dissection depth. Usually, it is about 25 cm for adults, and among them, it is 24 cm for women and 26 cm for men.

[0035] S4. The semi-circular tube 1 was removed from the oral cavity position, as shown in Figure 11. By the action of the opening 11, when the semi-circular tube 1 was removed, the position of the guide tube 2 was not affected, and the guide tube 2 was not pulled, and the patient's airway was not further stimulated.

[0036] S5. As shown in Figures 12 to 14, a nasotracheal intubation tube B was advanced into the airway along the guide tube 1 until an appropriate intubation depth was reached.

[0037] S6. After confirming again that the nasotracheal intubation B was placed successfully using conventional auscultation or end-tidal carbon dioxide detection methods, the guide tube 2 was removed (Figure 15). The nasotracheal intubation B was then fixed in place according to the normal steps and connected to the respiratory support equipment. At this point, the conversion from oral intubation to nasotracheal intubation was completed.

[0038] The present invention can effectively help change oral tracheal intubation to nasotracheal intubation, reduce multiple risks that may exist during the tracheal exchange process, improve the respiratory support method for patients, and improve the prognosis.

[0039] Although the specific embodiment of the present invention has been described in detail above, it is merely an example, and the present invention is not the same as the specific embodiment described above. For those skilled in the art, any similar modifications and replacements made to the present invention are within the scope of the present invention. Therefore, any equivalent modifications and modifications made without departing from the spirit and principle of the present invention should be included in the protection scope of the present invention.
