Double-balloon single-lumen tracheal catheter

Abstract

The invention relates to a double-balloon single-lumen tracheal catheter. The double-balloon single-lumen tracheal catheter comprises a catheter body and a catheter respiration connector; a first catheter balloon and a second catheter balloon are arranged on the head portion of the catheter body, the catheter body is wrapped in both the first catheter balloon and the second catheter balloon, and the first catheter balloon is located between the second catheter balloon and a catheter body end portion hole; the first catheter balloon and the second catheter balloon are connected with a balloon charging and discharging mechanism; and a catheter side hollowed-out area is arranged on the outer side surface of the arc head portion of the catheter body, the catheter side hollowed-out area is located between the first catheter balloon and the second catheter balloon, the catheter side hollowed-out area communicates with a surgery side lung operation pipe, and through the surgery side lung operation pipe and the catheter side hollowed-out area, required operation can be conducted on a surgery side lung. According to the double-balloon single-lumen tracheal catheter, deflation and inflationoperation on the surgery side lung can be effectively achieved, convenience and the controllability of secretion elimination operation in a surgery process are improved, and the stability and reliability of a ventilation state of a single lung or double lungs can be effectively improved.

Description

technical field [0001] The invention relates to a tracheal catheter, in particular to a double-bag single-lumen tracheal catheter, which belongs to the technical field of tracheal catheters. Background technique [0002] In thoracic surgery, in order to free up enough surgical space, it is necessary to suspend breathing of the operated lung to collapse the operated lung, and at the same time, perform one-lung ventilation on the non-operated lung to meet the oxygen supply demand during the operation. After the lung operation is completed, it is necessary to temporarily ventilate the surgical side lung to test the airtightness of the surgical side lung resection margin to avoid complications such as pneumothorax caused by air leakage from the surgical side lung resection margin after the chest wall is directly closed. After the operation, double-lung ventilation is required to re-expand the lung on the surgical side that collapsed during the operation to achieve the purpose of...

AI Technical Summary

Problems solved by technology

[0005] 2) Due to the double-lumen bronchial catheter with two ventilation lumens and the influence of the catheter wall, the overall outer diameter of the double-lumen bronchial catheter is relatively thick, causing greater damage to the glottis and throat during intubation, and more complications. The most common is postoperative sore throat and hoarseness, even leading to dislocation of the arytenoid cartilage;

[0006] 3) The double-lumen bronchial catheter is limited by the inner diameter of the trachea of ​​the human body. Due to the limitation of the inner diameter of the glottis in children, the diameter of a single lumen is small, and it is impossible to produce thinner products that can be used by children, which limits its use in children. applications in groups

The current double-lumen bronchial catheter can only be used in children over 10 years old;

[0007] 4) The double-lumen bronchial catheter is limited by the inner diameter of the trachea of ​​the human body, resulting in a small diameter of a single lumen, which is not conducive to the secretion cleaning operation

[0009] 1) The placement and positioning of the bronchial occluder is difficult and requires the assistance of video tools. That is to say, the video tool and the bronchial occluder need to be operated at the same time. The operation is relatively complicated and requires experienced anesthesiologists to implement it smoothly;

[0010] 2) When positioning the bronchial occluder, the video tool and the bronchial occluder need to be inserted into the cooperating single-lumen endotracheal tube at the same time. For patients over 6 years old, children under 6 years old are difficult to use;

[0011] 3) When in use, the bronchial occluder is used to block the bronchial opening of the surgical side lung, and it is difficult to discharge the gas in the surgical side lung; it is impossible to clean the secretions of the surgical side lung; when the surgical side lung needs to be inflated, the bronchial The gas in the occluder air bag is discharged, and the lung on the operated side is inflated through the single-lumen tube, which will cause blood or secretions in the bronchi of the operated side lung to flow into the main trachea, resulting in pollution of the non-operated side lung and the main trachea;

[0012] 4) The balloon of the bronchial occluder is not easy to fix, and the lung isolation effect is unstable. It is easy to shift during the operation, resulting in poor lung isolation effect, and the high-pressure and low-volume balloon is easy to cause mucosal damage;

[0013] 5) If the tube cannot be extubated after the operation, respiratory support is required, and the single-lumen endotracheal tube used together needs to use subglottic secretions to clean the endotracheal tube, and the cost will increase significantly;

[0014] 6) The production process of the bronchial occluder is relatively difficult and expensive, which is several times that of the double-lumen bronchial catheter, which places a heavy economic burden on the patient

This operation is a positioning operation, the depth needs to be relatively accurate, and it often takes several times to complete, which can lead to mucosal damage, bleeding, and even bronchospasm at the bronchial opening;

[0019] 4) Pulmonary hemorrhage and mucus accumulation on the surgical side above the single-lumen endotracheal tube balloon, lack of effective suction method, easy to cause atelectasis due to blood clots or mucus blocking the bronchial opening of the surgical side, or blood or mucus flowing into the non-operative side bronchus and Main trachea, leading to contamination of non-operated lung and main trachea

[0020] 5) If the tube cannot be extubated after the operation, respiratory support is needed, and the single-lumen endotracheal tube used together needs to use subglottic secretions to clean the endotracheal tube, and the cost will increase significantly

[0021] 6) When the single-balloon single-lumen endotracheal tube is used for long-term respiratory support, the same position may be compressed by the airbag, resulting in ischemia and necrosis of the mucosa in the trachea, and even ulcers and scar formation, resulting in narrowing of the tracheal cavity

[0022] In summary, there is a lack of a simple, effective, safe and practical method that can effectively exhaust, inflate, and clean up secretions on the surgical side of the lung during surgery, and does not require extubation and intubation when respiratory support is required at the end of the operation. It can also clean up subglottic secretions during respiratory support, and the position of the sealed air bag can be rotated to prevent the mucous membrane of the inner wall of the trachea from being compressed by ischemia and necrosis. It is a single-lung and double-lung ventilation management tool
