It has the advantages of being easy to master, convenient and fast, and having a high success rate. It has been widely used in clinical practice and is a relatively effective method for dealing with difficult airways. Therefore, lightwands have been widely used.

[0003] For example, the patent with patent number CN215275231U includes a light guide rod and a handle. The light guide rod is inserted at the left center of the handle. A drug outlet hole for drug administration is distributed on the outer side of one end of the light guide rod away from the handle, and a guide sleeve is fixed to the other end of the handle.

[0004] Although the above-mentioned device can bend continuously to ensure smooth intubation, since the light stick and the tracheal tube are inserted into the patient's trachea in a bent state, after the light stick is in place, the tracheal tube may be moved when the light stick is removed from the tracheal tube, causing the position of the tracheal tube left in the patient's trachea to shift, increasing the patient's discomfort and possible trauma risk, thereby affecting the smooth progress of intubation. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Below is the attached figure Figures 1 to 4 The technical solution of the utility model is further illustrated by specific implementation methods.

[0026] like Figure 1-4As shown, a light stick with a lubricating function comprises a handle 1, a connecting sleeve 2, a light stick body 3 and an LED lamp bead 4, wherein the connecting sleeve 2 is installed at one end of the handle 1, the light stick body 3 is connected to the end of the connecting sleeve 2 away from the handle 1, the LED lamp bead 4 is installed at the end of the light stick body 3 away from the connecting sleeve 2, a liquid reservoir 31 is provided inside the light stick body 3, and lubricating liquid is stored in the liquid reservoir 31, and a plurality of mounting grooves connected to the liquid reservoir 31 are provided on the outer wall of the light stick body 3, and a ball 32 is rollingly installed in each of the mounting grooves.

[0027] In the present solution, a plurality of ball bearings 32 are arranged so that during the process of separating the light stick body 3 from the tracheal tube, the ball bearings 32 on the outer wall of the light stick body 3 and the tracheal tube generate friction, thereby rotating, and then the lubricating liquid in the liquid storage tank 31 is coated on the inner wall of the tracheal tube, thereby reducing the friction between the light stick body 3 and the tracheal tube, making it smoother when the light stick body 3 is taken out of the tracheal tube, and avoiding the tracheal tube being moved when the light stick body 3 is taken out of the tracheal tube, thereby causing the position of the tracheal tube left in the patient's trachea to shift, thereby affecting the smooth intubation. This helps to reduce the patient's discomfort and reduce possible damage to the tissue.

[0028] like Figure 1 , 2 As shown in Figure 4, an oxygen supply tube 33 is installed inside the light stick body 3, and a connector 21 is installed at the outer end of the connecting sleeve 2. One end of the oxygen supply tube 33 is connected to the connector 21. An air outlet hole 34 is opened on the outer wall of the light stick body 3. Both ends of the air outlet hole 34 pass through the side wall of the light stick body 3. The other end of the oxygen supply tube 33 extends into the air outlet hole 34 and is connected to the air outlet hole 34.

[0029] Specifically, the oxygen supply machine is connected to the connector 21, and the oxygen supply machine delivers oxygen to the oxygen supply tube 33 through the connector 21, and then delivers oxygen to the air outlet 34 through the oxygen supply tube 33 for discharge, thereby providing oxygen to the patient during the intubation process and reducing the probability of hypoxia in the patient during the intubation process.

[0030] Furthermore, when oxygen is supplied, part of the lubricating fluid in the endotracheal tube will flow into the inner wall of the patient's respiratory tract, thereby reducing the friction between the endotracheal tube and the inner wall of the respiratory tract during the process of inserting and removing the endotracheal tube, helping to reduce the patient's discomfort and reduce possible damage to the tissue.

[0031] like Figure 4As shown, the two open ends of the air outlet 34 are provided with elastic sealing rings 341, the inner wall of the elastic sealing ring 341 is formed with an annular protrusion 342, the upper end of the annular protrusion 342 is provided with a first elastic sealing pad 343, and the center of the first elastic sealing pad 343 is provided with a cross groove.

[0032] Specifically, during the oxygen supply process, when oxygen enters the air outlet 34, the first elastic sealing pad 343 is affected by the airflow and moves toward the outside of the elastic sealing ring 341 to expand, so that the gas can be discharged from the air outlet 34 to provide oxygen. However, when the first elastic sealing pad 343 is not in the oxygen supply state, it can use its own toughness to reset, and use the annular protrusion 342 to support the first elastic sealing pad 343, so as to prevent the first elastic sealing pad 343 from expanding toward the inside of the elastic sealing ring 341, thereby sealing the air outlet 34 and reducing the probability of phlegm in the respiratory tract entering the air outlet 34 and causing blockage.

[0033] like Figure 2-3 As shown, a liquid injection hole connected to the liquid storage tank 31 is opened on the outer side of the light rod body 3, a second elastic sealing gasket is installed in the liquid injection hole, and a cross groove is provided at the center of the second elastic sealing gasket.

[0034] Specifically, lubricating liquid can be conveniently added to the liquid storage tank 31 through the liquid injection hole, and the second elastic sealing pad is automatically provided to block the liquid injection hole to prevent the lubricating liquid in the liquid storage tank 31 from flowing out through the liquid injection hole.

[0035] like Figure 1-3 As shown, the other end of the oxygen supply pipe 33 is fixedly connected to a conical cylinder 331 which is in communication therewith, and the diameter of the conical cylinder 331 at one end close to the oxygen supply pipe 33 is larger than the diameter of the end away from the oxygen supply pipe 33, and the conical cylinder 331 is located in the air outlet 34.

[0036] Specifically, when oxygen flows out through the conical tube 331, the flow rate of oxygen can be increased, so that the oxygen can push open the first elastic sealing pad 343 to achieve the oxygen supply effect.

[0037] like Figure 2 As shown, a plurality of the balls 32 are distributed in an annular shape and equidistantly on the outer side wall of the light rod body 3 .

[0038] Specifically, the plurality of balls 32 are distributed in an annular shape and at equal intervals, so that the lubricating oil can be applied more evenly, thereby reducing the friction between the optical rod body 3 and the tracheal tube.

[0039] like Figure 1 As shown, the outer wall of the handle 1 is provided with anti-slip grooves.

[0040] Specifically, the anti-slip grooves can increase the friction between the handle 1 and the palm of the medical staff, thereby preventing the handle 1 from slipping during the intubation process.

[0041] like Figure 1 As shown, a positioning plug 35 is detachably sleeved on the outer side wall of the light rod body 3 .

[0042] Specifically, the positioning plug 35 can limit the length of the light stick body 3 inserted into the tracheal tube, and can fix the light stick body 3 after the light stick body 3 is inserted into the tracheal tube.

[0043] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
