Description

Single-cavity single-bag single-double-lung ventilation catheter
Technical Field
The invention relates to a tracheal catheter, in particular to a single-cavity single-bag single-double-lung ventilation catheter, and belongs to the technical field of tracheal catheters.
Background
In thoracic cavity operation, in order to vacate enough operation space, the operation side lung needs to be made to pause breathing so that the operation side lung collapses, and meanwhile, the non-operation side lung is made to be ventilated in a single lung to meet the oxygen supply requirement in the operation. After lung operation is finished, the operation side lung needs to be ventilated temporarily, the airtightness of the operation side lung incisal margin is detected, and complications such as pneumothorax and the like caused by air leakage of the operation side lung incisal margin after the chest wall is closed directly are avoided. After the operation is finished, ventilation of the two lungs is needed, so that the collapsed operation side lung is expanded again during the operation, and the purpose of breathing and exchanging gas is achieved.
Currently, single lung ventilation is performed, most notably and most commonly by the administration of a double lumen bronchial catheter to manage the airway. The double-lumen bronchial catheter has the following disadvantages:
1) the double-lumen bronchial catheter is limited by the inner diameter of the trachea of a human body, so that the diameter of a single lumen is small, and when a single lung is ventilated, particularly asthma and COPD (chronic obstructive pulmonary disease) patients, the airway pressure is high, and the injury of the non-operative side lung can be caused. When a patient is accompanied with the pulmonary bullae, the pulmonary bullae are easy to rupture, and pneumothorax is generated;
2) the double-cavity bronchial catheter is provided with two ventilation tube cavities, and the influence of the catheter wall is added, so that the whole outer diameter of the double-cavity bronchial catheter is thick, the injury to glottis and laryngopharynx during intubation is large, more complications are caused, and most commonly, postoperative throat pain and hoarseness even arytenoid cartilage dislocation is caused;
3) the double-cavity bronchial catheter is limited by the inner diameter of the trachea of a human body, and the diameter of a single lumen is small due to the fact that a child is limited by the inner diameter of a glottis, so that a thin product which can adapt to children cannot be produced, and the application of the double-cavity bronchial catheter in children is limited. The current double-cavity bronchial catheter can be used by children over 10 years old at least;
4) the double-cavity bronchial catheter is limited by the inner diameter of the trachea of a human body, so that the diameter of a single lumen is small, and sputum suction operation is not facilitated. When some patients with poor lung function or patients who need mechanical breathing support cannot recover spontaneous breathing after operation due to other reasons, the double-cavity bronchial catheter needs to be pulled out and the single-cavity tracheal catheter needs to be inserted again, so that breathing management and sputum suction operation during the breathing support period are facilitated. The workload of an anaesthetist is increased, meanwhile, the related adverse reactions caused by intubation of a patient are increased, and in some patients with poor intubation conditions, even the conditions of anoxia, sudden cardiac arrest and even death caused by intubation failure are increased.
The bronchus obturator cooperates with the single-cavity endotracheal tube to be the most common method for ventilating and managing the airway of the single lung outside the double-cavity endotracheal tube, the tube does not need to be replaced when the breathing support of the endotracheal tube needs to be kept after the operation, the bronchus obturator can be pulled out, but the bronchus obturator also has a plurality of defects:
1) the bronchus stopper is difficult to place and position, and needs a video tool to assist, namely, the video tool and the bronchus stopper need to be operated simultaneously, so that the operation is complex and can be smoothly carried out by an anesthesiologist with rich experience;
2) when the bronchial plug is positioned, a video tool and the bronchial plug are required to be synchronously placed into a single-cavity tracheal catheter matched for use, and the lumen of the single-cavity tracheal catheter is determined to be not smaller than 5.5mm, namely, the bronchial plug can only be used for patients over 6 years old, and is difficult to use for children under 6 years old;
3) when in use, the bronchus blocking device is used for blocking the bronchus mouth of the lung at the operation side, and is difficult to discharge the gas in the lung at the operation side; the sputum suction operation cannot be performed on the operated side lung; when the operation side lung is required to be inflated, the air in the bronchus stopper air bag needs to be discharged, and the operation side lung is inflated through the single-lumen tube, so that blood or secretion in the bronchus of the operation side lung flows into the main trachea, and the non-operation side lung and the main trachea are polluted;
4) the balloon of the bronchial plug is not easy to fix, the lung isolation effect is unstable, the lung isolation effect is poor due to easy displacement in the operation, and the mucosa is easily damaged by the high-pressure low-capacity balloon;
5) if the tube can not be pulled out after the operation, the breathing support is needed, and the matched single-cavity tracheal catheter needs to use the subglottic sputum suction tracheal catheter, so the cost is obviously increased;
6) the bronchus stopper has larger manufacturing process difficulty and high price, is multiple times of a double-cavity bronchus catheter, and has heavier economic burden for patients.
At present, when a child lacks an effective single-lung breathing management tool, a single-cavity tracheal catheter is often used to insert a non-operative side for single-lung ventilation, and of course, the single-cavity tracheal catheter can also be used for a group outside the child, but the defect of the single-cavity tracheal catheter is very obvious:
1) the single-cavity tracheal catheter needs to be placed into a non-operative side bronchus, so that the bronchus opening of the lung at the operative side is basically blocked, gas in the lung at the operative side is difficult to discharge, the lung at the operative side is not beneficial to collapse, and sufficient operation space is not beneficial to operation;
2) when the operation side lung needs to be inflated during or after the operation, the single-cavity tracheal catheter needs to be retreated a little, and the opening at the head end of the single-cavity tracheal catheter is retreated into the main tracheal catheter so as to complete the inflation of the operation side lung under the ventilation of the two lungs. The infantile airway is short, the trachea catheter is easy to fall off the airway due to the operation of withdrawing the trachea, and the trachea cannula in an emergency lateral position can be generated, so that oxygen deficiency, even sudden cardiac arrest and even death can be caused;
3) when the operation side lung needs to be expanded temporarily in the operation, the single-cavity tracheal catheter needs to retreat a little, the opening at the head end of the single-cavity tracheal catheter retreats into the main tracheal tube and is completed under the ventilation of the two lungs, and then the head end of the single-cavity tracheal catheter needs to be re-placed into the non-operation side placing tube. The operation is a positioning operation, the depth needs to be accurate, and the operation can be completed only by a plurality of times, so that the injury and bleeding of mucosa at the opening of a bronchus can be caused, and even the bronchospasm can be caused;
4) the operative side pulmonary hemorrhage and mucus are accumulated above the single-cavity tracheal catheter air bag, an effective suction method is lacked, and the operative side pulmonary hemorrhage and mucus are easy to block the opening of the operative side tracheal catheter due to blood clots or mucus, or the non-operative side pulmonary hemorrhage and main tracheal catheter are easy to be polluted due to blood or mucus flowing into the non-operative side tracheal catheter and the main tracheal catheter.
In a word, a simple, effective, safe and practical single-lung ventilation management tool which can effectively exhaust and expand the operation side lung in the operation and does not need to be operated by drawing and inserting a tube when respiratory support needs to be kept at the end of the operation is clinically lacked.

In the embodiment of the invention, the length direction of the catheter balloon 2 is consistent with the length direction of the catheter body 1, but the length of the catheter balloon 2 is far smaller than that of the catheter body 1. In order not to affect the release of gas through the side vent part of the catheter, the catheter balloon 2 wraps the corresponding outer wall of the side vent part of the catheter on the head part of the catheter body 1, and the side vent part of the catheter is positioned between two ends of the catheter balloon 2, namely, the outer ring of the side vent part of the catheter is the catheter balloon 2 wrapping the catheter body 1, and the lower edge of the catheter balloon 2 is positioned between the side vent part of the catheter and the end hole 54 of the catheter body.
When the operation lung is a left lung, the catheter body 1 is inserted into an air passage by adopting a common technical means after anesthesia, the depth and the position of the catheter body 1 are adjusted, the catheter balloon 2 is positioned at the right side of the carina, namely the front half part of the catheter balloon 2 is positioned in the opening of a bronchus at the right side, the rear half part of the catheter balloon 2 is positioned behind the carina in the bronchus, and the side vent part of the catheter is positioned behind the carina in the main bronchus at the moment, so that the side vent part of the catheter is opposite to the opening of the. Appropriate amount of gas is filled into catheter utricule 2, and catheter utricule 2 inflation, first half shutoff right side bronchus of catheter utricule 2, and simultaneously, second half shutoff main trachea of catheter utricule 2, pipe body 1 can breathe through pipe body tip hole 54 and support the right lung, and simultaneously, pipe body 1 can breathe through pipe side portion of ventilating and support the left lung to can implement two lungs and ventilate. In practice, the front half of the catheter balloon 2 refers to the part of the catheter balloon 2 adjacent to the catheter body end hole 54, and the rear half of the catheter balloon 2 refers to the part of the catheter balloon 2 away from the catheter body end hole 54.
Before the operation is started, the connection between the catheter breathing connector at the tail part of the catheter body 1 and the breathing machine/anesthesia machine is disconnected to suspend breathing support for three minutes, negative pressure suction can be carried out in the catheter body 1 if necessary, the gas in the right lung passes through the end hole 54 of the catheter body, the gas in the left lung passes through the side ventilation part of the catheter and is exhausted out of the body through the tail part of the catheter body 1, and at the moment, the left lung and the right lung are both in a shriveled state.

That is, the whole process needs to retreat the catheter body 1 into the main trachea, and only the catheter body 1 needs to be rotated, so that the problem caused by the existing retreat of the catheter body 1 into the main trachea can be avoided, and the convenience and the reliability of the operation during the ventilation of the double lungs are improved.
After the operation of the left lung is finished, the ventilation of the two lungs is required to be recovered in time, so that the collapse time of the operated lung can be reduced as much as possible, the reduction of the surface active substances of the alveoli is reduced, and the occurrence probability of atelectasis caused by the reduction of the surface active substances of the alveoli is reduced. After the left lung operation is determined to be finished, when the thoracic cavity can be closed, the catheter body 1 is retreated by 3cm-5cm, so that the catheter balloon 2 is retreated into the main trachea, the stimulation of the catheter balloon 2 to the carina can be reduced, and the cardiovascular reaction is reduced; at the moment, the side vent part of the catheter corresponds to the side wall of the main trachea and can form a blind hole state, so that the normal ventilation of the double lungs is not influenced.
