TECHNICAL FIELD

[0001] The utility model relates to tracheal catheter technical field more specifically, relate to a kind of for tracheal catheter's fixer. BACKGROUND

[0002] Tracheal catheter intubation refers to the "special tracheal catheter" through glottis into the tracheal catheter technology, which can provide the best conditions for airway patency, ventilation and oxygen supply, respiratory tract suction and prevention of aspiration. Tracheal catheter intubation is also a necessary means for implementing general anesthesia, especially for anesthesia in prone position surgery. It is difficult to observe the tracheal catheter intubation situation because of the special body position of the patient. Therefore, fixing the tracheal catheter is the most important thing to ensure the patency of the respiratory tract of the patient during surgery, especially prone position surgery, and is the most important problem during surgery.

[0003] Current problems: 1. Surgery in special position, especially prone position surgery, tracheal catheter is pulled by gravity and moves out of the mouth. 2. The oil stains and sweat stains on the patient's face, as well as the increased outflow of saliva due to prone position, often cause the adhesive tape fixing the tracheal catheter to be wet, reducing the adhesion of the adhesive tape, and losing the adhesion between the catheter and the skin, thereby losing the fixing effect and causing the risk of tracheal catheter falling out. 3. The position and condition of the tracheal catheter in prone position are not easy to observe. Even if it is found in time, it is very difficult to reinsert and fix due to the influence of the patient's surgical position and surgical site. 4. The conventional soft tracheal catheter intubation is fixed with a hard dental pad. The fixation should not be too tight to prevent deformation of the lumen, nor too loose to prevent loosening, thereby increasing the difficulty of fixation. UTILITY MODEL CONTENT

[0019] EMBODIMENT

[0020] In the embodiment, the fixing device for the tracheal tube is combined with the tracheal tube 1, Figure 1 — Figure 3 as shown in the drawing, which comprises the tracheal tube 1, the material of the tracheal tube 1 can be selected from soft PVC material, silica gel material, polyurethane material or polypropylene material,

[0021] Soft PVC: soft PVC itself is soft, suitable for use in normal temperature environment.

[0022] Silica gel: silica gel is high temperature resistant, non-deformable and non-aging, and the silica gel tracheal catheter has good antibacterial property.

[0023] Polyurethane: polyurethane tracheal catheter has good flexibility and is not easy to break even after repeated bending, and has excellent antibacterial and waterproof properties.

[0024] Polypropylene: the polypropylene tracheal catheter has high strength, good toughness, high transparency and is not easy to deform. The tracheal catheter 1 is sleeved with a fixer 2 for fixing the tracheal catheter 1. The fixer 2 can freely slide on the tracheal catheter 1, so as to conveniently adjust the position of the fixer on the tracheal catheter. The material of the fixer 2 is preferably medical plastic, which has the advantages of low cost, simple processing, toughness, durability, chemical inertness and high biological safety. The fixer 2 comprises a sliding sleeve 21 sleeved on the tracheal catheter 1. The sliding sleeve 21 is annular and is made of medical plastic. The sliding sleeve 21 is uniformly provided with inclined sliding grooves. The sliding grooves penetrate the sliding sleeve and are directed towards the tracheal catheter 1. The sliding grooves are provided with a fixing rod 23 for fixing the sliding sleeve by sliding. In order to avoid damaging the tracheal catheter 1 when fixing the sliding sleeve 21, the end of the fixing rod 23 close to the tracheal catheter 1 is spherical.

[0025] The end of the fixing rod 23 away from the tracheal catheter 1 is provided with a driving ring 24 for driving the fixing rod 23. The small diameter of the driving ring 24 is larger than the diameter of the tracheal catheter 1. The driving ring 24 is provided with a sliding groove 25 for mounting the fixing rod 23. The fixing rod 23 can freely slide on the sliding groove 25. When a force is applied to the driving ring 24, the driving ring 24 will drive the fixing rod 23 to slide on the sliding groove 25 and in the sliding groove, thereby fixing the sliding sleeve 21.

[0026] The two ends of the sliding sleeve 21 are provided with connecting ears 22 for mounting the woven belt. The connecting ears 22 are symmetrically mounted on the circumferential wall of the sliding sleeve 21. The connecting ears 22 are provided with through holes for mounting the woven belt.

[0027] The tracheal catheter 1 is sleeved with a driving sleeve 26 for driving the movement of the driving ring 24. The small diameter of the driving ring 24 is provided with internal threads. The driving sleeve 26 is provided with external threads for cooperating with the internal threads of the driving ring 24. In this way, when the driving sleeve 26 is rotated, the driving sleeve 26 can drive the movement of the driving ring 24 through the thread cooperation with the driving ring 24, thereby driving the movement of the fixing rod 23 to realize the function of fixing the sliding sleeve 21. The use of the driving sleeve 26 can make the fixing operation of the sliding sleeve 21 more convenient.

[0028] The one end of the driving sleeve 26 close to the sliding sleeve 21 is installed on the sliding sleeve 21 through a bearing, so that the driving sleeve 26 can be fixed in position and automatically rotate at the same time, when the driving sleeve rotates, the driving ring 24 can avoid rotating through the cooperation of the fixed rod 23 and the sliding groove 25, and the one end of the driving sleeve 26 away from the sliding sleeve 21 is provided with an extension ring, which can facilitate the control of the driving sleeve 26.

[0029] It should be understood that, for those skilled in the art, improvements or changes can be made according to the above description, and all these improvements and changes shall belong to the protection scope of the appended claims of the utility model.
