Problems solved by technology

[0003] In the course of clinical treatment, it was found that the existing tracheal intubation, especially the children's tracheal intubation, is too short. The connection environment between the intubation tube and the patient's breathing circuit is not loose, which makes respiratory management difficult, and the efficiency of expectoration is relatively low, which affects the patient's respiratory management to a certain extent

Embodiment 1

[0026] The main structure of this embodiment, such as figure 1 As shown, an extended endotracheal intubation tube with an enlarged end and an anti-bending type includes an endotracheal intubation body. One end of the endotracheal intubation body is the front end 1 of the intubation tube. shape, the diameter of the other end gradually increases to form an enlarged end 2, which is screwed together with the intubation joint 3, the front end 1 of the intubation is provided with an anti-leakage device 4, and one side of the tube wall of the endotracheal intubation body is connected with an anti-leakage device. The inflatable tube 6 connected with the leakage device 4 is provided with a small hole 7 between the leakage prevention device 4 and the opening 9, and a metal wire 5 is embedded in the lumen of the endotracheal tube body. In the present invention, the anti-leakage device 4 is provided at the front end of the intubation tube. The anti-leakage device 4 is a thin-walled cuff,...

Embodiment 2

[0028] In this embodiment, on the basis of Example 1, the length of the endotracheal tube body is further limited to 24-36 cm. The length of the existing endotracheal tube apart from the incisors (teeth) is only about 8 cm. If the length is increased by 4cm, the total length of the endotracheal tube will reach 24-36cm, effectively increasing the length of the endotracheal tube located outside the incisors, and ensuring the looseness of the connection environment between the endotracheal tube and the patient's breathing circuit when the patient is under general anesthesia in the prone position . Other parts of this embodiment are the same as those of Embodiment 1, and will not be repeated here.

Embodiment 3

[0030]In this embodiment, on the basis of the above-mentioned embodiments, it is further defined that the initial position of the enlarged end 2 matches the inner diameter of the front end 1 of the cannula, and the inner diameter of the enlarged end 2 gradually increases to 7.5 mm from the initial end to the end. For tracheal intubation in children, the inner diameter and depth of the front end 1 of the intubation should match the age of the child, and the insertion depth of the tracheal intubation body should reach the middle of the trachea of ​​the child. The relationship between the inner diameter of the front end of the intubation tube and the age of the child is: the inner diameter of the front end of the endotracheal tube body ID (mm) = 2.5 + 0.4 × age, and the relationship between the depth of the intubation tube and the age of the child is: the insertion depth of the endotracheal tube body L = 12 +Age / 2, the part other than the depth of endotracheal intubation, that is,...

Abstract

The invention discloses a lengthened fracturing resistant and pressing resistant type trachea cannula with an expansion end. The lengthened fracturing resistant and pressing resistant type trachea cannula with the expansion end comprises a trachea cannula body, one end of the trachea cannula body is a cannula front end, an opening is formed in the pointed part of the cannula front end, the opening is a smooth spoon shape, the other end of the trachea cannula body is enlarged gradually in diameter to form the expansion end, the expansion end is in matching screw connection with a cannula connector, an anti-leakage device is arranged at the cannula front end, an air inflating pipe communicated with the anti-leakage device is connected to one side of the trachea cannula body, a small hole is formed between the anti-leakage device and the opening, and a metal wire is embedded in a cannula cavity of the trachea cannula body. According to the lengthened fracturing resistant and pressing resistant type trachea cannula with the expansion end, due to the fact that the trachea cannula is lengthened, the fitness of the connection environment of the trachea cannula and a breathing pipeline under the situation that a patient is at a prone position under a general anesthesia condition is guaranteed, and the comfort of the patient is improved; the expansion end is arranged, the trachea cannula body is lengthened, the inner diameter of the cannula is enlarged at the same time, air passage resistance is not increased, and sputum can be sucked conveniently; furthermore, the steel wire in the trachea cannula spirally is arranged, twisting and wrinkling are prevented, the service life of the trachea cannula is prolonged, operation is simple, and manufacturing cost is low.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an anti-bending type endotracheal intubation tube with an extended belt and an enlarged end. Background technique [0002] Endotracheal intubation refers to the technique of inserting a special endotracheal tube and intubation tool into the patient's trachea through the mouth to perform endotracheal anesthesia or rescue the patient. It is the most reliable means to keep the upper airway unobstructed. Therefore, endotracheal intubation is widely used clinically. One end is inserted into the trachea through the mouth, and the other end is connected to the artificial ventilator. Establishing an artificial airway to solve the problems of ventilation and expectoration is a very important rescue measure. [0003] In the course of clinical treatment, it was found that the existing tracheal intubation, especially the children's tracheal intubation, is too short. The connection environmen...
