TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, and particularly relates to a tracheal tube with positioning function. BACKGROUND

[0002] The visual tracheal intubation under infrared guidance is an innovative medical technology combining infrared technology and visualization equipment. Its core principle is to emit infrared light through an infrared laser pen, conduct it to the front end of the tracheal tube through an optical fiber to form a light spot, and the doctor observes the light spot position and combines the real-time display of the laryngeal structure by the visualization equipment to accurately guide the intubation path. This technology significantly improves the accuracy and safety of intubation, and is especially suitable for emergency, anesthesiology and intensive care scenes, especially in the treatment of patients with difficult airway or special body position, which can effectively reduce complications such as vocal cord injury and tracheal mucosa injury, shorten the operation preparation time, and compared with the traditional blind insertion technology which relies on experience and hand feeling, the visual tracheal intubation under infrared guidance can provide real-time image feedback, so that the doctor can see the reality, greatly improve the first intubation success rate, and reduce the risk of repeated adjustment, and provide a safer and more efficient respiratory tract management solution for patients.

[0003] In the actual use process of the existing device, the guide wire and the catheter are fixed in a simple way, the slippage rate is high, the operation is easily interrupted due to the change of the patient's body position or the complex airway, the manual control of the tail end of the guide wire depends on the doctor's experience during use, the positioning error is large, and in obese, short neck or airway deformity patients, repeated attempts are required. Therefore, a tracheal tube with positioning function is proposed. SUMMARY

[0021] After the guide wire 3 is installed inside the installation slot 1, the fixed plate 22 arranged at the front end of the installation slot 1 clamps the two sides of the second adjusting shell 15 to ensure the stability of the connection of the guide wire 3, and the guide wire 3 is moved by starting the electric telescopic rod 5, so as to adjust the distance of the guide wire 3 at the front end of the catheter 2 to adjust according to different airway conditions. During the movement of the guide wire 3, the second adjusting shell 15 slides inside the installation slot 1, so that the protruding block 23 drives the friction wheel 17 to rotate through friction, the rotation of the friction wheel 17 drives the first piston 20 to reciprocate, so as to continuously deliver gas into the second air cavity 21 to increase the internal gas pressure, and then drive the second piston 27 to move to both sides, so that the fixed plate 22 automatically separates to both sides during the extension and retraction of the guide wire 3, and the locking is released. When the adjustment is completed, the first piston 20 is automatically reset. The air inlet and the air outlet are arranged on both sides of the first piston 20, and the area of the air inlet is larger than that of the air outlet. After the position adjustment is completed, the air can be discharged through the air outlet to realize the reset.

While the fixed plate 22 moves, the first spring 25 expands and contracts. After the adjustment is completed, the fixed plate 22 can be driven to return to its original position by the first spring 25, thereby continuing to be fixed.
