Single-cavity single-bag tracheal catheter capable of conveniently implementing single-lung and double-lung ventilation

Abstract

The invention relates to a ventilation catheter, in particular to a single-cavity single-bag tracheal catheter capable of conveniently implementing single-lung and double-lung ventilation, and belongsto the technical field of tracheal catheters. An air bag vacancy area is arranged on the side face of a catheter sealing bag at the head end of the catheter and communicates with a surgical lung operation tube, when the catheter sealing bag is inflated, the sealing air bag with a side groove can be formed, the head opening of the catheter body is placed into a non-surgical-side lung, the non-surgical-side lung bronchial opening is sealed in cooperation with the catheter sealing bag, and respiratory support can be conducted on the non-surgical-side lung. Meanwhile, the air bag vacancy area isadjusted to correspond to the bronchial opening of the operation-side lung, and the operation side lung can be shrunken and expanded and secreta can be cleaned in combination with a operation-side operation tube, so that the convenient management of single-lung ventilation is effectively realized; and the head opening of the catheter body is placed in the main trachea, the catheter sealing bag isalso located in the main trachea and can be used as a single-cavity tracheal catheter, and full-function double-lung or single-lung ventilation management is achieved.

Description

technical field [0001] The invention relates to a ventilation catheter, in particular to a single-cavity single-bag tracheal catheter which can conveniently implement single-lung and double-lung ventilation, and 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 ...

Problems solved by technology

[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, it is necessary to simultaneously place the video tool and the bronchial occluder into the cooperating single-lumen endotracheal tube. 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 orifice 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, it needs to be The gas in the airbag of the bronchial occluder is discharged, and the single-lumen tube inflates the operated lung, which will cause blood or secretions in the operated lung bronchi to flow into the main trachea, resulting in pollution of the non-operated 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] In short, there is a lack of a simple, effective, safe and practical single lung that can effectively exhaust, inflate, and clear secretions in the operated side lung during thoracic surgery. Ventilation Management Tools
