Description

Technical Field

[0001] This utility model relates to the field of airway intubation technology, specifically a disposable temperature-controlled laryngeal mask airway tube. Background Technology

[0002] Tracheal intubation is a technique that involves inserting a specially designed endotracheal tube through the glottis into the trachea. This technique provides optimal conditions for airway patency, ventilation and oxygenation, respiratory suction, and prevention of aspiration. However, existing tracheal intubation tubes have limitations. The inflation size of the cuff tip is difficult to adjust after insertion into the trachea. Although existing tracheal intubation tubes are equipped with temperature sensors, these sensors cannot make proper contact with the trachea, resulting in inaccurate data. Furthermore, existing tracheal intubation tubes cannot drain refluxed gastric fluid. While some tracheal intubation tubes are equipped with cameras, the images are often unclear, and their functionality is relatively limited. Therefore, a disposable temperature-controlled laryngeal mask airway has been developed to address these issues. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a disposable temperature-controlled laryngeal mask airway to solve the problems mentioned in the background section.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a disposable thermostatic laryngeal mask airway tube, comprising an airbag head and a curved tube, wherein the airbag head and the curved tube are fixedly connected, and the interior of the curved tube is provided with a first insertion channel, a second insertion channel, a water injection pipe, a camera connection line, and a temperature sensor connection line; a temperature sensor is installed on the top surface of the curved tube; a groove is provided at the bottom of the airbag head, the groove communicating with the second insertion channel; a camera is installed inside the groove, and flexible LED light strips are installed on both sides of the camera; a flow channel groove is provided at the end edge of the airbag head, one end of the flow channel groove is connected to a first drainage tube, and the other end of the flow channel groove is connected to a second drainage tube; a pressure gauge is also installed on the curved tube, and the pressure gauge is connected to the airbag delivery tube.

[0005] In a preferred embodiment of this invention, the camera connection cable is connected to both the camera and the flexible LED light strip.

[0006] In a preferred embodiment of this invention, the temperature sensor connection wire is connected to the temperature sensor.

[0007] As a preferred technical solution of this utility model, the first insertion channel, the second insertion channel, the water injection pipe, the camera connection line, the temperature sensor connection line, and the airbag delivery pipe are all integrated in the bend. One end of the first insertion channel and the water injection pipe passes through the side wall of the second insertion channel and communicates with the groove opening.

[0008] As a preferred embodiment of this utility model, the air supply tube of the airbag is connected to the airbag head, and the first drainage tube and the second drainage tube are both connected to the flow channel groove.

[0009] In a preferred embodiment of this invention, the airbag head and the curved tube are integrated.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the cuff head of this endotracheal tube has flow channel grooves on both sides, and the flow channel grooves are connected to drainage tubes. The flow channel grooves and drainage tubes are used to drain the liquid in the patient's airway, so as not to block the patient's airway.

[0011] The temperature sensor of this airway tube is located at the top of the bend. When the airway tube is inserted, the temperature sensor on the bend can fit against the roof of the patient's oral airway, thereby more accurately monitoring the patient's temperature.

[0012] This airway tube is equipped with a camera inside, allowing for a more direct view of the airway and glottis. It also uses flexible LED light strips for illumination, which can capture information inside the airway more clearly.

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0018] Example: Please refer to Figure 1-2This utility model provides a technical solution: a disposable thermostatic laryngeal mask airway tube, including an airbag head 1 and a curved tube 2, which are fixedly connected. The curved tube 2 has a first insertion channel 3, a second insertion channel 4, a water injection pipe 5, a camera connection line 6, and a temperature sensor connection line 7 inside. A temperature sensor 15 is installed on the top surface of the curved tube 2. The bottom of the airbag head 1 has a groove 10, which is connected to the second insertion channel 4. A camera 11 is installed inside the groove 10. Flexible LED light strips 12 are installed on both sides of the camera 11. A flow channel groove 16 is provided at the end edge of the airbag head 1. One end of the flow channel groove 16 is connected to a first drainage tube 13, and the other end of the flow channel groove 16 is connected to a second drainage tube 14. A pressure gauge 9 is also installed on the curved tube 2. The pressure gauge 9 is connected to the airbag delivery tube 8. The pressure gauge 9 can be used to control the expansion pressure of the airbag head 1 in real time.

[0019] The camera connection cable 6 is connected to the camera 11 and the flexible LED light strip 12 respectively. The camera 11 and the flexible LED light strip 12 are used to capture images of the patient's airway and glottis, and the video is transmitted to the monitoring monitor through the camera connection cable 6.

[0020] Temperature sensor connection cable 7 is connected to temperature sensor 15, providing power to temperature sensor 15 and also using temperature sensor 15 to sense the patient's body temperature and output the detection data to the monitoring device in real time.

[0021] The first intubation channel 3, the second intubation channel 4, the water injection pipe 5, the camera connection cable 6, the temperature sensor connection cable 7, and the air bag delivery pipe 8 are all integrated in the bend 2, so that they will not cross or become messy, making it convenient for doctors to use. One end of the first intubation channel 3 and the water injection pipe 5 passes through the side wall of the second intubation channel 4 and connects to the groove opening 10.

[0022] The air supply tube 8 is connected to the air head 1. The first drainage tube 13 and the second drainage tube 14 are both connected to the flow channel 16. The liquid in the flow channel 16 can be transported out by using the first drainage tube 13 and the second drainage tube 14.

[0023] The airbag head 1 and the curved tube 2 are integrated and will not detach.

[0024] Working principle: The disposable temperature-controlled laryngeal mask airway tube is used by expelling the gas from the cuff head 1 and inserting the laryngeal mask airway tube into the patient's trachea. Gas is then injected into the cuff head 1 through the cuff delivery tube 8, causing the cuff head 1 to inflate. The pressure gauge 9 can be used to visually monitor the inflation pressure of the cuff head 1, allowing staff to stop the injection of gas and avoid under-inflation or over-inflation. During insertion, the temperature sensor 15 at the top of the curved tube 2 is in contact with the top wall of the patient's airway for more accurate monitoring of the patient's body temperature. When the cuff head 1 inflates to the set point, the flow channel 16 is opened, and the fluid in the patient's airway flows through the flow channel 16 into the first drainage tube 13 and the second drainage tube 14. One end of the first drainage tube 13 and the second drainage tube 14 is connected to a negative pressure device, which can quickly suction out the fluid in the airway. A camera 11 is also installed inside the cuff head 1, and is illuminated by flexible LED light strips 12 on both sides of the camera 11 to make the camera capture clearer images.

[0025] The above embodiments merely illustrate the implementation of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
