In many cases, awake intubation is required. Anyone who is estimated to have difficulty in tracheal intubation or has one of the following conditions should choose awake endotracheal intubation: (1) Incomplete airway obstruction, such as excessive phlegm, hemoptysis, and neck mass compression Trachea; ② Digestive tract obstruction, such as pyloric obstruction, intestinal obstruction; ③ Satiety, such as acute trauma, labor injury; ④ Inability to tolerate deep anesthesia, such as old age, shock, critical illness, weight loss and frailty; ⑤ Certain patients undergoing acupuncture surgery.

When awake tracheal intubation is performed for a patient, the intubation tube needs to be inserted into the patient's trachea. Since the front end of the intubation tube is operated in the patient's body, it cannot be directly observed. The current operation is performed by the doctor's experience, which is easy to Insertion into the esophagus has a low one-time success rate and requires repeated exploration, which not only delays time, but also increases the pain of the patient despite local anesthesia.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

As shown in Figures 1-5, the present invention provides a gas navigation visualization awake tracheal intubation device, including a gas guide tube 1 and a tracheal tube 3, the gas guide tube 1 is provided with an opening 11 at a position close to the oblique mouth end, It also includes a guide tube 2 inserted from one end of the gas guide tube 1 and extended from the opening 11. The guide tube 2 is provided with a camera 21 and an air guide tube 22 extending through the end. One end of the air conduit 22 is connected to the detector 5 , and the other end is provided with a collector, and the detector 5 is communicated with the air pump 4 .

In order to allow the guide tube 2 to pass through the opening 11 smoothly, a guide plug 12 is provided inside the gas guide tube 1 at the position of the opening 11, and the guide plug 12 is provided with a guide tube 2 is guided through the bevel of the opening 11.

As an embodiment of the present invention, the patient will be supine, take the modified head position, the anesthetist will stand on the patient's head, and before the tracheal intubation operation, the surface anesthesia of the throat must be perfected, and then the tracheal guide tube 1 Insert the esophagus into the esophagus through the nose or through the mouth, and adjust the up, down, reverse, and clockwise directions appropriately until the strongest tubular breath sound can be heard at the outer mouth of the tracheal guide tube 1, which can be regarded as the opening at the beginning of the tracheal guide tube 1. 11 is basically aligned with the glottis, and note the number of graduations on the tube wall.

Next, the guide tube 2 is inserted into the tracheal guide tube 1. When the insertion reaches the mark on the tracheal guide tube 1, the guide tube 2 just slides out of the opening 11 through the guide plug 12 in the tracheal guide tube 1.

The right end of the guide tube 2 is placed at the trachea of the patient's oral cavity, so that the air tube 22 in the guide tube 2 collects the exhaled gas of the patient through the collector at its end, and detects the collected gas of the patient through the detector 5. _CO2 concentration. Constantly change the position of the right end of the guide tube 2 at the patient's trachea, and observe at different positions. At the same time, you can use the camera 21 to observe the environment in the trachea, detect the _CO concentration of the patient's exhaled gas, and then place the guide tube. The right end of 2 is moved to the position with the highest _CO concentration and marked on the guide tube 2. Then pull out the tracheal guide tube 1, re-introduce the corresponding tracheal tube 3, and guide the tracheal tube 3 to the marked position to ensure that the insertion process is uniform and stable, so as to complete the entire intubation operation. After the operation is completed, routine identification is required. The position of the tracheal tube 3, at this time, if the tracheal tube 3 has entered the trachea, the outer port of the tracheal tube 3 can hear and clear air exhalation, and finally the guiding tube 2 is pulled out.

In order to provide illumination for the camera head 21, the end of the camera head 21 is installed with lighting lamp beads 23, and the lighting lamp beads 23 are arranged in a circle around the camera head 21, which can not only provide lighting, but also can be seen from the outside of the patient. Point of light, providing an indication of location.

As an embodiment of the present invention, the air guide tubes 22 are four, which are evenly arranged around the camera 21, and a detachable inner ring 110 is installed at the front end or both ends of the guide tube 2. The inner side of the inner ring 110 is provided with limit sleeves 120 having the same number as the air guide tubes 22 . The limit sleeves 120 are provided with limit holes 130 for the air guide tubes 22 to pass through. Or inner threads 101 are provided on the inner side walls of both ends, the inner ring 110 is connected with the inner thread 101, the inner thread 101 is also connected with a washer 102, the inner ring 110 is abutted against the washer 102, and the guide tube 2. It is integrally formed with the gasket 102, and the limiting sleeve 120 and the limiting hole 130 are integrally formed, so that the strength and stability of the structure can be improved, and the dimensional accuracy can be improved.

According to the different positions where the airway tube 22 is inserted into the trachea, the detected _CO2 concentration is marked according to the position with the highest _CO2 concentration. The following are the _CO2 concentration values measured by the airway tube 22 at four different positions in the trachea:

Table 1: _CO2 Concentration Test Table for Location 1

Table 2: _CO2 Concentration Test Table for Location 2

Table 3: _CO2 Concentration Test Table for Location 3

Table 4: _CO2 Concentration Test Table for Location 4

The farther the right end of the guide tube 2 is from the center of the patient's trachea, the greater the difference in CO ₂ concentration of the gas collected by the collectors on the four air tubes 22 . When the CO ₂ concentrations of the gases collected by the four collectors are similar, it indicates that the right port of the guide tube 2 has been located in the center of the trachea. As shown in Table 1-4 above, the average CO ₂ concentrations of the four tested locations The values are 276ppm, 475ppm, 581ppm and 596ppm respectively. It can be seen that the concentrations at positions 3 and 4 are relatively close, so the center of the trachea is in the area between positions 3 and 4.

In this embodiment, the detector 5 is connected with a trachea 6, and one end of the trachea 6 is connected to the trachea 22 through the flange 7, and the flange 7 can be connected to a plurality of trachea 22 at the same time. The gas in the airway 22 is sucked into the detector 5 .

The detector 5 is connected to the air pump 4 through a connecting hose 8 , and the connecting hose 8 can be deformed to facilitate the moving operation of the guide tube 2 .

The opening 11 is oval in shape with a short axis length of not less than 6 mm and a long axis length of 1-2 cm. This shape allows the guide tube 2 to pass through the opening 11 quickly and is not easily blocked.

Although the present invention has been described above with reference to the embodiments, various modifications may be made and equivalents may be substituted for parts thereof without departing from the scope of the invention. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present invention can be combined with each other in any way, and the description of these combinations is not exhaustive in this specification. For the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
