[0001] The present invention relates to the technical field of medical instruments, and in particular to a breathing-guided endotracheal intubation guide wire and an application thereof in endotracheal intubation. Background Art

[0002] At present, it is well known that endotracheal intubation is often required to rescue patients clinically. Since the endotracheal tube is too soft, a guide wire needs to be added to the endotracheal tube when inserting it into the patient's trachea in order to form a certain curvature and strength. The original guide wire is generally ordinary copper wire. Although it has a certain curvature and strength, its disadvantage is that it can only be inserted blindly. Summary of the invention

[0003] The present invention provides a breathing-guided endotracheal intubation guide wire and its application in endotracheal intubation. The image of the front end of the guide tube can be viewed in real time through a monitor, and the forward direction can be adjusted under the guidance of the monitor, thereby improving the success rate of intubation.

[0004] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a breathing-guided endotracheal intubation guidewire, comprising: a guide tube, a main channel is provided in the center of the guide tube along the length direction, and a first air groove and a second air groove are distributed on both sides of the main channel, and a storage groove is provided at one end of the guide tube corresponding to the main channel, and the inner side wall of the storage groove is provided with a plurality of guide grooves connected to the first air groove and the second air groove; the outer wall of the guide tube at one end away from the storage groove is respectively provided with air vents connected to the first air groove and the second air groove; a camera and a monitor, the camera is embedded in the storage groove, the monitor is arranged at the end of the guide tube away from the storage groove, and the camera is electrically connected to the monitor through a video cable running through the main channel, and the outer wall of the video cable is in contact with the openings of the first air groove and the second air groove.

[0005] Preferably, a medicine channel is also provided along the length direction on one side of the guide tube corresponding to the main channel, and the medicine channel and the first air groove and the second air groove are evenly distributed around the main channel; a plurality of injection holes connected to the medicine channel are provided on the outer wall of the storage groove; a medicine interface is provided on the outer wall of the guide tube away from the camera end.

[0006] Preferably, three control channels are evenly distributed around the main channel in the guide tube, each of the control channels is provided with a control wire, a control ring is provided around the main channel at the bottom end of the storage groove, and each of the control wires is connected to the control ring; it also includes a control handle connected to the end of the guide tube away from the camera, and three toggle sliders are circumferentially provided on the outer wall of the control handle, and each of the control wires is connected to the toggle slider.

[0007] Preferably, the control ring is an iron component.

[0008] Preferably, the use of a breathing-guided endotracheal intubation guide wire in endotracheal intubation includes the following steps: putting the endotracheal intubation tube on the outside of the guide tube, and exposing the front end of the guide tube by more than 30 centimeters; connecting any one of the ventilation ports to the oxygen supply interface for oxygen delivery; pushing the guide tube to the glottis through the patient's mouth; using a monitor to observe the forward direction and advancement angle of the guide tube; adjusting the direction of the guide tube head by controlling the sliders on the handle; when the camera reaches the patient's glottis, pushing anesthetic into the drug channel through the drug interface, and spraying the anesthetic outward through the injection hole to anesthetize the patient's glottis; after anesthesia is completed, continuing to push the guide tube to complete the guidance; pushing the endotracheal intubation tube, and when the endotracheal intubation tube is in place, retracting and pulling out the guide tube to complete the intubation operation.

[0009] Preferably, the orientation guidance of the head of the guide tube is achieved by placing and moving a magnet on the patient's neck.

[0010] The beneficial effect of the present invention is that the guide wire function can be realized according to the mechanical properties of the video line, and the tracheal insertion and guidance can be completed. The monitor collects images in real time through the camera, and the camera is equipped with a fisheye lens, so that the front end and lateral images of the guide tube can be seen without adjusting the camera angle, and the image viewing in various directions can be realized with the video software in the monitor. The first gas groove and the second gas groove are used for the delivery of oxygen and the discharge of carbon dioxide, and because the video line is used for isolation, when there is resistance to gas supply or exhaust, as the side walls of the first gas groove and the second gas groove are elastically deformed, the two are interconnected by the main channel, thereby realizing gas pressure release. The drug channel is used to deliver anesthetics. Since the drug channel is not connected to the first gas groove, the second gas groove and the main channel, the delivery pressure of the anesthetic drug can be guaranteed, and it can be sprayed to the anesthesia area by the injection hole. The control handle and the control wire are similar to the traditional direction adjustment sheath tube, so the three control wires are pulled and released by three sets of toggle sliders to break the force balance of the control ring, so that the guide tube is bent and deformed, and the forward direction is adjusted under the guidance of the monitor, thereby improving the success rate of intubation. In addition, during the insertion of the guide tube, the position of the head of the guide tube can be guided by placing and moving a magnet on the patient's neck. BRIEF DESCRIPTION OF THE DRAWINGS
