Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to a tracheal intubation guiding groove for cooperating with a fiberoptic bronchoscope and a using method thereof. Background Art

[0002] During tracheal intubation, situations such as failed intubation, cancelled surgery, and life-threatening hypoxia and asphyxia of the patient often occur due to difficult airways where the epiglottis and glottis cannot be exposed. The commonly used video laryngoscope technology in clinical practice sometimes can only expose the epiglottis and cannot directly expose the glottis. Therefore, in the existing fiberoptic bronchoscope technology, the fiberoptic bronchoscope is passed through the tracheal catheter and can directly enter under the epiglottis. By bending the front-end lens, the glottis can be directly observed and the airway can be entered, thus solving the problem of exposing the glottis. However, when inserting the tracheal catheter along the fiberoptic bronchoscope into the glottis, it often fails at the "last step" of inserting the tracheal catheter into the airway because the fiberoptic bronchoscope is too soft and has no support. Moreover, the wedge-shaped opening at the front end of the tracheal catheter is similar to a physical inclined plane, which can also cause a certain degree of cutting and damage to the vocal cords on both sides of the glottis and the nearby tissues. Repeated friction causes edema and bleeding in the glottis and pharynx, affecting the patient's life safety, postoperative recovery, and comfort during the perioperative period. Summary of the Invention

[0003] Aiming at the deficiencies of the existing technology, the present invention provides a tracheal intubation guiding groove for cooperating with a fiberoptic bronchoscope and a using method thereof. The specific technical solutions are as follows:

[0004] A tracheal intubation guiding groove for cooperating with a fiberoptic bronchoscope includes a tube body and a guiding hole arranged in the tube body. The guiding hole includes a clamping portion arranged at the front end of the tube body, a guiding portion arranged at the rear end of the tube body, and a clamping portion arranged between the clamping portion and the guiding portion.

[0005] The aperture of the clamping portion is smaller than that of the guiding portion. The wall thickness of the tube body at the clamping portion gradually decreases along the insertion direction close to the tube body, and the wall thickness of the tube body at the guiding portion gradually increases along the direction away from the insertion direction of the tube body. A side opening penetrating through both ends of the tube body is arranged on the side wall of the tube body.

[0006] Preferably, the apertures of the clamping portion and the guiding portion gradually decrease along the direction close to the clamping portion.

[0007] Preferably, the clamping portion is in the shape of a thin-wing fish mouth and an arc surface is arranged at the front end of the clamping portion.

[0008] Preferably, the guiding portion is round and smooth at the side opening.

[0009] Preferably, the tube body is a soft tube with openings at both ends and a shape that can be molded.

[0010] Preferably, an anti-swallowing joint is arranged at the end of the guiding portion, and the tail end of the anti-swallowing joint has a standard aperture and can be connected to a ventilator.

[0011] Preferably, the material used for the tube body is medical silicone.

[0012] A method for using a tracheal intubation guide groove in conjunction with a fiberoptic bronchoscope comprises the following steps in sequence:

[0013] (S1): Bend the tube body according to the actual situation of the patient to ensure that the front end of the clamping part is aligned with the patient's part to be tested when the tube body is inserted;

[0014] (S2): insert the tube into the patient's mouth, then pass the fiberoptic bronchoscope with endotracheal tube through the guide part, and let the front end of the fiberoptic bronchoscope pass through the front opening, and then insert it into the patient's part to be tested under the visual guidance of the fiberoptic bronchoscope. The tube can protect the fiberoptic bronchoscope during the fiberoptic bronchoscope examination and play a role in oxygen supply;

[0015] (S3): After the tracheal tube is inserted in place, the fiberoptic bronchoscope with the tracheal tube is separated from the tube body through the side opening, and the tube body is removed from the patient's mouth. After removal, the fiberoptic bronchoscope is withdrawn along the tracheal tube. After the tracheal tube is successfully fixed, it can be connected to the ventilator for ventilation. If the intubation fails, the front end of the clamping part has been placed in the airway, and the tube body can be left in the mouth. The ventilator or other oxygen supply equipment is connected to the rear end of the anti-swallowing connector to supply oxygen to the patient to ensure life safety.

[0016] The present invention has the following beneficial effects:

[0017] The present invention uses the clamping part of the guide hole as the clamping position of the fiberoptic bronchoscope, and sets the guiding part of the guide hole as a hollow tube type, so as to realize the function of placing, supporting and guiding the fiberoptic bronchoscope. At the same time, the wall thickness of the tube body at the clamping part is gradually reduced along the insertion direction close to the tube body, so as to realize the purpose of passing through the glottis and reducing the physical damage to the glottis accessory tissue; and the present invention improves the clamping force of the tube body on the fiberoptic bronchoscope by coordinating the aperture of the clamping part with the clamping part, and solves the problem of insufficient support force for tracheal intubation under the guidance of the fiberoptic bronchoscope. At the same time, the present invention can be placed in the airway as a ventilation tool in special emergency situations to temporarily solve the patient's oxygen supply problem. During use, the present invention allows for better glottis exposure, higher intubation success rate, less physical damage, and fewer complications, while ensuring the patient's life safety and increasing the patient's perioperative comfort.

[0028] See Figures 1 to 3, in the present invention, a tracheal intubation guiding groove for cooperating with a bronchofiberscope includes a tube body 1 and a guiding hole 2 disposed within the tube body 1 for guiding the bronchofiberscope. The tube body 1 is a soft tube with openings at both ends and a shape that can be molded. The operator can bend and mold the tube body 1 according to the actual situation of the patient to ensure that the tube body 1 can be aligned with the part to be detected when inserted. At the same time, the material used for the tube body 1 is medical silica gel, ensuring that the present invention meets the medical industry standards during use. A side opening 3 penetrating both ends of the tube body 1 is provided on the side wall of the tube body 1, and the guiding portion 22 is round and smooth at the side opening 3. After the bronchofiberscope is inserted in place, the operator removes the tube body 1 along the bronchofiberscope from the patient's mouth and separates the bronchofiberscope from the tube body 1 at the side opening 3.

[0029] Further refer to Figures 1 to 2 , the guiding hole 2 includes a clamping portion 21 disposed at the front end of the tube body 1 for clamping the bronchofiberscope, a guiding portion 22 disposed at the rear end of the tube body 1 for guiding, and a clamping portion 23 disposed between the clamping portion 21 and the guiding portion 22. The clamping portion 21 is in the shape of a thin-winged fish mouth, and an arc-shaped surface 4 is provided at the front end of the clamping portion 21. The arc-shaped surface 4 prevents the tube body 1 from causing a certain degree of cutting and damage to the vocal cords on both sides of the glottis and the nearby tissues during the insertion process of the tube body 1. At the same time, it prevents the repeated friction of the tube body 1 from causing edema and bleeding in the glottis and pharynx, affecting the patient's life safety, postoperative recovery, and comfort during the perioperative period. An anti-swallowing joint 5 is provided at the end of the guiding portion 22, and a standard-caliber interface is provided at the tail end of the anti-swallowing joint 5 for connecting a ventilator, enabling the present invention to be used as a ventilation tool and placed in the airway under special circumstances.

[0030] Further refer to Figures 2 to 3 , the aperture of the clamping portion 21 is smaller than the aperture of the guiding portion 22, and the wall thickness of the tube body 1 at the guiding portion 22 gradually increases along the direction away from the insertion direction of the tube body 1. The wall thickness of the tube body 1 at the clamping portion 21 gradually decreases along the direction close to the insertion direction of the tube body 1. At the same time, the apertures of the clamping portion 21 and the guiding portion 22 gradually decrease along the direction close to the clamping portion 23. In the present invention, the clamping portion 21 of the guiding hole 2 is used as the clamping position of the bronchofiberscope, and the guiding portion 22 of the guiding hole 2 is set as a hollow tube type, realizing the functions of placing, supporting, and guiding the bronchofiberscope. At the same time, the wall thickness of the tube body 1 at the clamping portion 21 gradually decreases along the direction close to the insertion direction of the tube body 1, achieving the purpose of passing through the glottis and reducing physical damage to the tissues near the glottis. And the present invention improves the clamping force of the tube body 1 on the bronchofiberscope through the aperture cooperation between the clamping portion 23 and the clamping portion 21, solving the problem of insufficient supporting force of the tracheal catheter under the guidance of the bronchofiberscope.

[0031] The usage method of a tracheal intubation guiding groove for cooperating with a bronchofiberscope in the present invention successively includes the following steps:

[0032] (S1): Bend and mold the tube body according to the actual situation of the patient to ensure that the front end of the clamping portion is aligned with the part to be detected when the tube body is inserted;

[0033] (S2): Insert the tube body into the patient's mouth, then insert the fiberoptic bronchoscope with tracheal catheter through the guiding part. The front end of the fiberoptic bronchoscope passes through the front opening and is inserted into the part to be detected under the visual guidance of the fiberoptic bronchoscope. The tube body can protect the fiberoptic bronchoscope during fiberoptic bronchoscopy and can also play an oxygen supply role.

[0034] (S3): When the tracheal catheter is inserted in place, separate the fiberoptic bronchoscope with tracheal catheter from the tube body at the side opening, remove the tube body from the patient's mouth. After removal, withdraw the fiberoptic bronchoscope along the tracheal catheter. After the tracheal catheter is successfully inserted and fixed, it can be connected to a ventilator for ventilation. If the intubation fails and the front end of the clamping part has been placed in the airway, the tube body can be left in the oral cavity, and a ventilator or other oxygen supply device is connected to the tail end protrusion of the anti-swallowing joint to supply oxygen to the patient and ensure life safety.

[0035] In the present invention, the clamping part 21 of the guiding hole 2 is used as the clamping position of the fiberoptic bronchoscope, and the guiding part 22 of the guiding hole 2 is set as a hollow tube type, realizing the functions of placing, supporting and guiding the fiberoptic bronchoscope. At the same time, the wall thickness of the tube body 1 at the clamping part 21 is gradually reduced along the insertion direction close to the tube body 1, achieving the purpose of passing through the glottis and reducing physical damage to the tissues adjacent to the glottis. And through the aperture cooperation between the clamping part 23 and the clamping part 21, the present invention improves the clamping force of the tube body 1 on the fiberoptic bronchoscope, solving the problem of insufficient supporting force of the tracheal catheter under the guidance of the fiberoptic bronchoscope. At the same time, in special emergency situations, the present invention can be used as a ventilation tool and placed in the airway to temporarily solve the problem of oxygen supply for the patient. During the use process of the present invention, the glottis is better exposed, the intubation success rate is higher, the physical damage is smaller, the complications are fewer, while ensuring the life safety of the patient and increasing the comfort of the patient during the perioperative period.
