Description

Technical Field

[0001] This utility model relates to an endotracheal intubation tube, belonging to the field of medical supplies technology. Background Technology

[0002] During general anesthesia, the patient loses consciousness, muscles relax, and spontaneous breathing is suppressed. In order to maintain airway patency, ensure that air can smoothly enter the patient's lungs, and prevent airway obstruction caused by factors such as tongue falling back or increased respiratory secretions, endotracheal intubation is required.

[0003] In the prior art, such as the utility model with application number 202322800064.7, a endotracheal tube is disclosed. In order to solve the problem that when the sliding sleeve is fixed on the endotracheal tube, the endotracheal tube is easy to collapse when the spring and clamp are clamped on the outer wall of the tube due to its soft material, which affects ventilation, a support frame made of spiral steel wire is set inside the endotracheal tube body. This supports the tube wall without affecting the bending of the endotracheal tube. The locking mechanism is used to fix the limiting ring to ensure smooth ventilation of the endotracheal tube. In addition, the support frame can also improve the toughness of the endotracheal tube, making it easier for medical staff to intubate.

[0004] The above-mentioned applications still have shortcomings:

[0005] The inflation tube on the endotracheal tube has a certain length and cannot be retracted after use. The inflation tube may be hooked or pulled by other equipment or objects, which may cause the endotracheal tube to shift or even fall out, causing serious consequences for the patient. The inflation tube may also cause interference around the patient's head, affecting medical staff's observation of the patient and other operations. In addition, the endotracheal tube is in a bent state after installation, and the spiral steel wire is located inside the endotracheal tube, which makes the endotracheal tube very elastic. Although it ensures ventilation, it increases the pressure on the patient's trachea, causing pain in the trachea after extubation.

[0006] Therefore, an endotracheal intubation device was designed to optimize the above problems. Utility Model Content

[0007] The main purpose of this utility model is to provide a endotracheal tube. A fixing ring with a first limiting groove is fixed to the top of the endotracheal tube body to limit the top of the inflation tube. An adjusting ring with a second limiting groove is rotatably installed below the fixing ring to limit the middle position of the inflation tube. By controlling the rotation of the adjusting ring, the inflation tube can be wound around the endotracheal tube body, effectively preventing scattered inflation tube from interfering with the operation of medical personnel, thus improving practicality. An anti-bending mechanism consisting of a silicone sleeve and a spring is slidably installed on the endotracheal tube body, providing support and protection only at the bending area during use, ensuring smooth ventilation without increasing the pressure on the patient's trachea.

[0008] The objective of this utility model can be achieved by adopting the following technical solution:

[0009] An endotracheal tube includes an endotracheal tube body, an air bladder installed at the bottom of the endotracheal tube body, a plug located at the top of the endotracheal tube body, an inflation tube installed at the top of the endotracheal tube body and communicating with the inside of the air bladder, and an inflation connector at the top of the inflation tube. A fixing ring is fixedly provided at the top of the endotracheal tube body, and a first limiting groove is provided on the outer side of the fixing ring. An adjusting ring is rotatably installed at the top of the endotracheal tube body, and a second limiting groove is provided on the outer side of the adjusting ring. An anti-bend mechanism is slidably provided at the top of the endotracheal tube body.

[0010] Preferably, the surface of the endotracheal tube body has graduation lines along its length.

[0011] Preferably, the retaining ring is located below the plug, and the distance between the top of the retaining ring and the plug is 5-10mm.

[0012] Preferably, the distance between the bottom of the adjusting ring and the fixed ring and the end of the inflation tube is the same, and the upper and lower sides of the adjusting ring are provided with limiting rings, and the limiting rings are fixed on the outside of the endotracheal tube body and fit against the surface of the adjusting ring.

[0013] Preferably, the anti-bend mechanism includes a silicone sleeve and a spring. The silicone sleeve is fitted onto the endotracheal tube body, and the inner wall of the silicone sleeve fits against the outer side of the endotracheal tube body. A spring is provided inside the silicone sleeve, and the endotracheal tube body passes through the inside of the spring.

[0022] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0023] like Figure 1-Figure 4 As shown, this embodiment provides an endotracheal tube, including an endotracheal tube body 1, an air bag 2 installed at the bottom of the endotracheal tube body 1, a plug 3 located at the top of the endotracheal tube body 1, an inflation tube 4 installed at the top of the endotracheal tube body 1 and communicating with the inside of the air bag 2, and an inflation connector 5 at the top of the inflation tube 4. A fixing ring 6 is fixedly provided at the top of the endotracheal tube body 1, and a first limiting groove 7 is provided on the outer side of the fixing ring 6. An adjusting ring 8 is rotatably installed at the top of the endotracheal tube body 1, and a second limiting groove 10 is provided on the outer side of the adjusting ring 8. An anti-bend mechanism 11 is slidably provided at the top of the endotracheal tube body 1.

[0024] Overall working principle: After the endotracheal tube body 1 is inserted and connected to the ventilator or air source, the weight at the end of the endotracheal tube body 1 will increase, causing the end of the endotracheal tube body 1 to droop and bend. To avoid bending and blockage of the endotracheal tube body 1, the anti-bending mechanism 11 is slid to the stress area to support the endotracheal tube body 1 and ensure the ventilation effect of the endotracheal tube body 1. Then, the top of the inflation tube 4 is locked inside the first limiting groove 7, and the middle position of the inflation tube 4 is locked inside the second limiting groove 10. The rotation of the adjusting ring 8 is controlled to wrap the inflation tube 4 around the outside of the endotracheal tube body 1 and fold the inflation tube 4 to prevent the inflation tube 4 from naturally drooping and affecting the operation and observation of medical staff.

[0025] In this embodiment, the surface of the endotracheal tube body 1 is provided with scale lines along the length direction.

[0026] Local working principle: The use of scale lines makes it easy to determine the insertion depth of the endotracheal tube body 1.

[0027] In this embodiment, the retaining ring 6 is located below the plug 3, and the distance between the top of the retaining ring 6 and the plug 3 is 5-10mm.

[0028] Local working principle: When the inflation tube 4 is inserted into the first limiting groove 7, the fixed ring 6 and the plug 3 have a certain distance, so it will not affect the insertion of the inflation tube 4.

[0029] In this embodiment, the adjustment ring 8 is at the same distance from the bottom of the fixed ring 6 and the end of the inflation tube 4. Limiting rings 9 are provided on both the upper and lower sides of the adjustment ring 8, and the limiting rings 9 are fixed on the outside of the endotracheal tube body 1 and fit against the surface of the adjustment ring 8.

[0030] Local working principle: Since the adjusting ring 8 is located in the middle of the fixed ring 6 and the inflation tube 4, after the middle part of the inflation tube 4 is inserted into the second limiting groove 10, the rotation of the adjusting ring 8 can ensure the winding effect of the inflation tube 4.

[0031] In this embodiment, the anti-bending mechanism 11 includes a silicone sleeve 12 and a spring 13. The silicone sleeve 12 is fitted onto the endotracheal tube body 1, and the inner wall of the silicone sleeve 12 is in contact with the outer side of the endotracheal tube body 1. The spring 13 is provided inside the silicone sleeve 12, and the endotracheal tube body 1 passes through the inside of the spring 13.

[0032] Local working principle: During use, the silicone sleeve 12 is controlled to slide on the endotracheal tube body 1 and move to the force point of the endotracheal tube body 1. The silicone sleeve 12 and the spring 13 work together to support the area to ensure ventilation effect.

[0033] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
