In this embodiment, the thimble 330 has a triangular shape, and the inner cavity 320 has a funnel shape, which are not specifically limited in this embodiment of the present invention.

[0035] In one embodiment, as shown in FIG. 5, in the rod head 500, the installation height of the lamp 510 and the atomizing head 520 are the same, and the installation height of the camera is slightly lower than the installation height of the lamp 510 and the atomizing head 520. Therefore, the camera does not block the lamp 510 and the atomizing head 520. In order to obtain a clear image of a patient's trachea, the camera may be a high-definition camera, which is not specifically limited in the embodiment of the present invention. In order to improve the visual effect, the lamp 510 may be a high-brightness red light emitter, which is not specifically limited in the embodiment of the present invention.

[0036] In one embodiment, in order to effectively limit the lamp 510, the atomizing head 520 and the camera, a circumferential inner wall of the rod head 500 is inlaid with a porous pad, and the top of the porous pad is provided with round holes matching the lamp 510, the atomizing head 520 and the camera.

[0037] In one embodiment, in order to protect the position of the atomizing head 520, a porous metal mesh is adhered to the output end of the atomizing head 520.

[0038] In one embodiment, as shown in FIG. 1, the handle 100 is a cylinder, and the outer wall is provided with twill 110 to facilitate holding in use.

[0039] In one embodiment, in order to ensure the safety of the patient, the rod body 400, the circuit tube 410, and the rod head 500 may be made of medical-grade materials, which is not specifically limited in the embodiment of the present invention.

[0040] When the present invention is specifically used, firstly, the positions of the thyroid cartilage and the trachea of the patient are determined by observation. Then, open the flip cover 310 of the medicine compartment 300, and use the thimble 330 on the side wall of the inner cavity 320 to pierce the rubber sealing plug of the anti-inflammatory medicine liquid, so that the medicine liquid enters the inner cavity 320 through the thimble hole 340 and/or the filter hole 350, and passes through the transfer tube 360 connected to the inner cavity 320 to allow the medicinal solution to enter the pump body 200. The anti-inflammatory medicinal solution may also be directly poured into the inner cavity 320 of the medicine compartment 300.

[0041] Secondly, place a small cushion on the patient's neck to make the patient's head tilt back slightly to facilitate the patient's mouth opening. Then, pull the first arc frame 640 and the second arc frame 650 to make the first arc frame 640 and the second arc frame 650 unfolded and clamped on both sides of the patient's oral cavity or at the chin position, and the bracket 600 is clamped to the outside of the patient's oral cavity by means of the restoring force of a return spring connected to the first and second arc frames 640 and 650. The rubber plate adhered to the inner wall of the first arc frame 640 and the second arc frame 650 and the rubber block 660 adhered to the bottom thereof will increase the friction force, so that the bracket 600 is more stably fixed to the patient's face, and the skin of patient can be protected. Next, gently lift the patient's lower jaw forward and upward to increase the distance between the patient's upper and lower incisors and create a free space for the insertion of the visible light rod. At this time, pressing the first button 120 turns on the lamp 510 in the rod head 500, and pressing the third button 230 turns on the illumination lamp head 240 of the illumination lamp 220, which is used to illuminate the patient's oropharynx during the intubation process to facilitate observation of the condition of the pharynx of the patient. During the use, it can be determined whether the lamp 510 and the illumination lamp head 240 need to be turned on at the same time according to the needs of the implementation.

[0042] Next, hold the handle 100 in a pen-style manner, and gently insert the rod body 400 of the visible light rod with the tracheal tube into the deep part of the patient's throat along the natural arc of the throat. At the same time, rotate the rod body 400 of the visible light rod by 15° to 20° clockwise until the bright spot of the lamp 510 in the head 500 appears at a deeper level than the thyroid cartilage, at the position of the gap between the trachea and the muscle; then gently rotate the rod body 400 counterclockwise (at this time, it is usually unable to rotate counterclockwise and will be blocked), and retract the rod body 400 of the visible light rod at the same time. When the resistance to rotation in the counterclockwise direction disappears, usually the light of the lamp 510 can illuminate the trachea instantly. At this time, maintain the current position of the rod 500, and rotate it back and forth slightly clockwise and counterclockwise to find the best position of the light that illuminates the trachea, then gently forward the rod 400 by 2˜3 cm across the vocal cords, hold the position of the rod 400 with one's right hand, release the patient's jaw with one's left hand, hold the tracheal tube forward along the visible light rod into the trachea. Carefully observe the characteristics and location of the light spot formed by the lamp 510 on the neck and the distance to the thyroid cartilage and trachea, and adjust it dynamically to find the best position to illuminate the ventilation tube. At this time, the camera at the end of the circuit tube 410 in the rod head 500 can display the condition inside the trachea on the display screen 420 at that time, and can understand the internal condition of the patient's trachea more intuitively.

[0043] During the intubation, the bracket 600 sleeved on the rod 400 can provide support and positioning for the rod 400, which not only improves the stability of the rod 400 during the intubation, but also facilitates the rod body during the intubation. The angle at which the 400 is inserted into the trachea of the patient is adjusted accordingly to improve the efficiency of intubation.

[0044] When exiting the light rod, hold the handle 100 to apply force in the opposite direction, and simultaneously press the second button 210 on the pump body 200, so that the anti-inflammatory medicine liquid flows through the atomizing tube 370 through the pump body 200 and passes through the atomizing head 520 in rod head 500 to be sprayed into the corresponding part in the trachea of the patient, so that the inside of the trachea can be relieved and anti-inflammatory, and the probability of internal infection and the discomfort of the patient can be effectively reduced. Then, relieve the first arc frame 640 and the second arc frame 650 that are clipped to the sides of the patient's mouth or at the chin, the bracket 600 is removed from the patient's face.

[0045] The present invention provides an auxiliary visible light rod for multisource end-expiratory CO.sub.2 monitoring. At the time of intubation for a patient, the rod head is sent to the patient's trachea through the rod body. The cameras in the rod head and the rod body are connected to the rod body. The upper display screen observes the inside of the trachea to avoid the difficulties caused by direct laryngoscope intubation. A thimble with thimble holes is installed in the inner cavity of the medicine compartment. After piercing the top of the bottled anti-inflammatory agent, the anti-inflammatory agent enters the pump body through the transfer tube; during the process of removing the light rod, press the second button to trigger the pump body and spray the anti-inflammatory agent into the patient's trachea through the atomizing tube, so as to relieve the anti-inflammatory purpose, and also reduce the probability of bacterial infection and the patient's discomfort. The oropharynx can also be illuminated by a lamp. The present invention can be used with tracheal intubation for CO.sub.2 monitoring and positioning, and can effectively be used with tracheal intubation, so that the accuracy of tracheal intubation is high, the time is short, and it is not easy to cause side damage to patients. During tracheal intubation for a patient, the stability of the rod during the intubation can be improved by fixing the rod to the external sides of the patient's mouth or the jaw bracket, and the angle of the rod inserted into the patient's trachea can be adjusted during the intubation.
