) BACKGROUND OF THE INVENTION

Endotracheal intubation is one of the most effective and reliable methods for establishing artificial airway and is a necessary technique for general anaesthesia and emergency resuscitation. The traditional intubation method is implementing direct intubation with direct laryngoscope, but the airway conditions of patients vary widely. For some patients with poor intubation conditions, such as small mandible, short thyromental distance, raised glottis, restriction of mouth opening and limited neck movement, it is very difficult for direct laryngoscope intubation. The failure rate of the first intubation is o high. It requires repeated attempts to complete the intubation, which takes a long time and is easy to cause collateral damage to the patient. At present, it needs to cooperate with the monitoring of multi-source end-tidal carbon dioxide for determining the position of the tracheal tube in the body, as it is convenient to adjust the tracheal tube and can increase the efficiency of intubation and improve the above problems. However, this method is not perfect because of its own technical problem. Although it can cooperate with the sensor device to monitor the multi-source end-tidal carbon dioxide, the tracheal tube with sensor head needs to be moved or rotated for collecting data in order to ensure necessary adjustment that the tube can be adjusted during the intubation. These operations will cause synchronous rotation of the screen connected with the tube. It is difficult to observe the data in small display screen. The tracheal tube with integrated screen has relatively simple effect and cannot be stored effectively. Besides, it cannot remotely transfer real-time data during operation to provide effective data support and later communication and reference.

Referring to FIGs. 1 to 5, the device comprises a housing 100, a connection hose 200, a fixing bracket 300 and a display screen 400. Specifically, referring to FIG. 1, a hinge 110 is provided on the front sidewall of the housing 100. In particularly, the hinge 110 is fixedly connected with the front sidewall of the housing 100 by screws, and the movable plate of the hinge 110 is fixedly connected with a flip plate 120 by screws. The left sidewall of the connection hose 200 is fixedly installed on the right sidewall of the housing 100. In particularly, a sleeve ring is fixedly connected with the right sidewall of the housing 100 by bolts. The connection hose 200 is inserted inside the sleeve ring. The inside of the o connection hose 200 is electrically connected with a signal line 210, and the end of the signal line 210 is electrically connected with an tracheal tube 220. The end of the tracheal tube 220 is inlaid with a sensor head 230. The bottom of the display screen 400 is fixed to the top of the housing 100, in particularly the display screen 400 is placed on the top of the housing 100. The display screen 400 is convenient to display data. The display screen 400 can be a conventional model. Referring to FIG. 2, the left sidewall of the fixing bracket 300 is fixedly connected with the right sidewall of the housing 100. In particularly, the right sidewall of the housing 100 is fixedly connected with the sleeve ring and the fixing bracket 300 by bolts respectively. The right sidewall of the fixing bracket 300 is fixedly connected with the limit plate 310 by screws, and the front sidewall of the inner cavity 500 is fixedly connected with a clamping board by bolts. Referring to FIG. 4, the inner cavity 500 is fixedly installed on the housing 100. In particularly, the inside of the housing 100 is the inner cavity 500. The front sidewall of the clamping board is fixedly connected with a carbon dioxide detector 510, a frequency controller 520, a wireless sensor 530, a D/A converter 540, and a battery 550 respectively. The electrical input terminal of the carbon dioxide detector 510 is electrically connected with the electrical output terminal of the signal line 210. D The carbon dioxide detector 510, the frequency controller 520, the wireless sensor 530 and the D/A converter 540 are electrically connected in sequence. The electrical output terminal of the battery 550 is electrically connected with the electrical input terminals of the D/A converter 540, the frequency controller 520, and the wireless sensor 530 through wires respectively. Among them, the models of the carbon dioxide detector 510, the frequency controller 520, the wireless sensor 530, the D/A converter 540 and the battery 550 can be directly selected from commonly used models on the market. When using the device, firstly the operator needs to get familiar with the anatomy of the throat in advance, establishes spatial imaging of oropharyngeal o trachea and related structures in the mind, and observes the position of the thyroid cartilage and trachea of the patient before operation. Secondly, a small pad is placed under the patient's neck to make the patient's head slightly tilted back, which is convenient for the operator to open the mouth and lifts the patient's lower jaw forward and upward to increase the distance between the upper and lower incisors to create free space for the tracheal tube 220. Then the operator needs to hold the tracheal tube 220 in a writing position, and gently insert it into the deep larynx along the natural curve of the throat. During this process, the sensor head 230 of the tracheal tube 220 can detect the carbon dioxide in the patient's airway. When the sensor head 230 is closer to the centre of the trachea, the carbon dioxide concentration it detects is higher. The doctor can roughly determine the location of the front end of the tracheal tube 220 in the patient's throat according to the detected concentration of carbon dioxide and adjust the tracheal tube 220 to the direction with higher concentration of carbon dioxide, thereby rapidly insert the tracheal tube 220 into the patient's trachea. The data of carbon dioxide concentration can be transmitted to the carbon dioxide detector 510, and after analysis, it can be transmitted to the frequency controller 520. The frequency controller 520 contains a chip inside with a preset threshold. When the carbon dioxide concentration exceeds D the threshold, it will be transmitted to the D/A converter 540 and displayed through the display screen 400. Meanwhile, the data can be transmitted by the wireless sensor 530 which is convenient for data transmission, later communication and analysis. The internal situation of the patient can be more intuitively understood to facilitate the control of the tracheal tube 220. After intubation, the operator can remove the tracheal tube 220, press the tracheal tube 220 into the limit plate 310 and fix it with the fixing bracket 300 for storage. Further referring to FIG. 1, in order to shield the housing 100 and dissipate the internal heat, as a specific embodiment, the rear sidewall of the flip plate 120 is inlaid with a buckle while the front sidewall of the housing 100 is provided with a o slot matching with the buckle.

In order to facilitate the fixing of the side frame 140 and the placement of sundries, as a specific embodiment, the left sidewall of the housing 100 is fixedly connected with a cross plate by screws. The top of the cross plate is provided with a through-hole. A side frame 140 is sleeved inside the through-hole. The material of the side frame 140 is preferably a transparent acrylic plate. In order to facilitate the detection of the carbon dioxide concentration, as a specific embodiment, the sensor heads 230 are multiple and equably arranged along the circumference of the inner cavity of the tracheal tube 220. The electrical output terminal of the sensor head 230 is electrically connected with the electrical input terminal of the signal line 210. Referring to FIG.3 to FIG. 5, in order to place the display screen 400 and facilitate data typing, as a specific embodiment, the bottom of the display screen 400 is fixedly connected with the base 410 by screws. The right sidewall of the display screen 400 is provided with a connection hole and a data line is inserted into the connection hole.
