The solution aims to prevent the rubber retainer 103 from being exposed to air for extended periods during endotracheal tube use, thus preventing bacterial growth and protecting the patient's health. It is also more convenient to use and helps prevent the sliding ring 105 from causing the protective ring 106 to detach from the endotracheal tube body 101.

[0022] In this specific embodiment, the surface of the airway body 101 is provided with the rubber fixing plug 103. The airway body 101 passes through the tube sleeve 102. The sputum collection chamber 104 is installed at the end of the airway body 101 away from the tube sleeve 102. The surface of the airway body 101 is provided with the rubber fixing plug 103. A soft pad is installed on the surface of the rubber fixing plug 103, and a fixing iron ring is installed inside the rubber fixing plug 103. The tube sleeve 102 is provided inside the fixing iron ring. The airway body 101 passes through the tube sleeve 102, and a rubber column is installed on the airway body 101. The rubber column is located on one side of the rubber fixing plug 103, and a square rubber block is installed on the rubber column.

The other end of the endotracheal tube body 101 is equipped with the sputum collection chamber 104. The rubber fixing plug 103 has a frustum-shaped structure. When using the endotracheal tube, the rubber fixing plug 103 is held in the mouth for fixation. The fixing ring can ensure the compactness of the rubber fixing plug 103 structure and prevent wrinkles, making it convenient for people to use the endotracheal tube. At the same time, when there is pain, the rubber fixing plug 103 can be used to relieve pain, improving the practicality of the endotracheal tube. When the endotracheal tube is not in use, one end of the endotracheal tube body 101 can be inserted into the round hole on the square rubber block to fix the endotracheal tube. It also facilitates the carrying of the endotracheal tube and improves the applicability of the endotracheal tube for bronchoscopy. The above are all prior art, so this application does not describe them in detail.

[0023] The sliding ring 105 is slidably connected to the air duct body 101 and located on one side of the air duct body 101. The protective component is disposed on the sliding ring 105, the fixing component is disposed on the air duct body 101, and the limiting component is disposed on the side of the air duct body 101 away from the fixing component. The sliding ring 105 is sleeved on the air duct body 101 and can move along the direction of the air duct body 101. The upper surface of the sliding ring 105 is provided with the protective component. When the sliding ring 105 moves, it drives the protective component to move. When the protective component moves toward the rubber fixing plug 103, it can cover the rubber fixing plug 103. The fixing component is disposed on the air duct body 101 and is located between the sliding ring 105 and the rubber column in the prior art. After the protective component covers the rubber fixing plug 103, it can be in contact with the fixing component. The protective components work together to maintain a stable state, thus keeping the rubber fixing plug 103 within a sealed space. This prevents the rubber fixing plug 103 from being exposed to air for extended periods, thereby preventing bacterial growth. The limiting component is located on the side of the airway body 101 near the sputum collection chamber 104. When using the rubber fixing plug 103, the limiting component limits the sliding ring 105, preventing the sliding ring 105 from causing the protective component to detach from the airway body 101. During the use of the endotracheal tube, the sliding ring 105 allows the protective component to move on the airway body 101. This allows the protective component and the fixing component to work together to enclose the rubber fixing plug 103 within a sealed space, preventing the rubber fixing plug 103 from being exposed to air for extended periods and thus preventing bacterial growth. This protects the patient's health and is convenient to use.

[0024] Secondly, the protective ring 106 is fixedly connected to the sliding ring 105 and is located on one side of the sliding ring 105; the opening of the placement groove 107 is located on the side of the protective ring 106 away from the sputum collection chamber 104, the protective ring 106 is fixed to the upper surface of the sliding ring 105, the inner diameter of the protective ring 106 is larger than the maximum diameter of the rubber fixing plug 103, the protective ring 106 has the placement groove 107 inside, and the rubber fixing plug 103 can be completely located in the placement groove 107, thereby reducing the contact between the rubber fixing plug 103 and the air.

[0025] Meanwhile, the top ring 108 is fixedly connected to the air guide tube body 101 and located on one side of the air guide tube body 101; the positioning block 109 is fixedly connected to the top ring 108 and located on the side of the top ring 108 away from the protective ring 106; the insertion block 110 is fixedly connected to the protective ring 106 and detachably connected to the insertion block 110; the top ring 108 is fixed on the air guide tube body 101, the top ring 108 is located above the rubber fixing plug 103, the positioning block 109 is provided on the upper surface of the top ring 108, and the bottom of the positioning block 109 is connected to the top ring 106. The top ring 108 is connected, and the inner surface of the positioning block 109 is inlaid with a magnetic material. The insertion block 110 is fixed to the upper surface of the protective ring 106. The position of the insertion block 110 corresponds to the position of the positioning block 109. The insertion block 110 can be inserted into the top ring 108 and the positioning block 109. The insertion block 110 is made of metal, so that the insertion block 110 and the positioning block 109 generate mutual attraction and maintain a stable state. This allows the protective ring 106 to maintain a stable state after covering the rubber fixing plug 103, preventing the rubber fixing plug 103 from being in contact with air for a long time.

[0026] When using the endotracheal tube for bronchoscopy in this embodiment, during the use of the endotracheal tube, the sliding ring 105 causes the protective ring 106 to move on the endotracheal tube body 101. This allows the insertion block 110 at the top of the protective ring 106 to be inserted into the positioning block 109 of the top ring 108. This ensures that the protective ring 106 can maintain a stable state after covering the rubber fixing plug 103, keeping it within a sealed space. This prevents the rubber fixing plug 103 from being exposed to air for extended periods, thus preventing bacterial growth and protecting the patient's health. The method is also convenient to use.

[0028] Based on the first embodiment, please refer to Figure 4 , Figure 4 This is a schematic diagram of the overall structure of the catheter for assisting bronchoscopy in the second embodiment. The limiting component in this embodiment includes a limiting ring 201 and a protective pad 202.

[0029] In this specific embodiment, the limiting ring 201 is fixedly connected to the airway body 101 and located on the side of the airway body 101 near the sputum collection chamber 104; the protective pad 202 is fixedly connected to the limiting ring 201 and located on one side of the limiting ring 201. The limiting ring 201 is located below the sliding ring 105, and the limiting ring 201 is fixed together with the airway body 101. The protective pad 202 is provided on the upper surface of the limiting ring 201. The pad 202 is made of soft rubber and has anti-slip and wear-resistant properties. When the rubber fixing plug 103 is needed, the sliding ring 105 moves the protective ring 106 downward, so that the protective ring 106 moves onto the limiting ring 201, thereby limiting the sliding ring 105. The protective pad 202 also provides a buffer protection for the sliding ring 105, preventing the sliding ring 105 from pulling the protective ring 106 away from the air guide tube body 101, making it easy to use.

[0030] When using the bronchoscope catheter of this embodiment, when the rubber retainer 103 is needed, the sliding ring 105 moves the protective ring 106 downward, so that the protective ring 106 moves onto the limiting ring 201, thereby limiting the sliding ring 105. The protective pad 202 provides buffer protection for the sliding ring 105, preventing the sliding ring 105 from pulling the protective ring 106 away from the airway body 101, thus facilitating use.
