Description

Single-cavity single-sac tracheal catheter capable of conveniently implementing single-lung and double-lung ventilation
Technical Field
The invention relates to an air duct, in particular to a single-cavity single-sac air duct capable of conveniently implementing single-lung and double-lung ventilation, belonging to the technical field of air ducts.
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 administering the airway using a double lumen bronchial catheter. 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 because a child is limited by the inner diameter of the glottis, the diameter of a single lumen is small, a thin product which can adapt to children cannot be produced, and the application of the double-cavity bronchial catheter in child groups is limited. At present, the double-cavity bronchial catheter can be used by children over 10 years old;
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 secretion cleaning operation is not facilitated. When the operation is finished, the double-cavity bronchial catheter needs to be pulled out and the single-cavity tracheal catheter needs to be inserted again, so that the breathing management and secretion cleaning 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 bronchial blanking plug is difficult to place and position, and needs a video tool to assist, namely, the video tool and the bronchial blanking plug need to be operated at the same time, the operation is complex, and the operation can be smoothly carried out by an anaesthetist with rich experience;
2) When the bronchus blocking device is positioned, a video tool and the bronchus blocking device need to be synchronously placed into a single-cavity tracheal catheter which is matched with the video tool and the bronchus blocking device for use, and the lumen of the single-cavity tracheal catheter is determined to be not smaller than 5.5mm, namely, the bronchus blocking device 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 stopper is used for blocking the mouth of a bronchus of the lung at the operation side, and is difficult to discharge the gas in the lung at the operation side; the secretion cleaning operation cannot be carried out 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 trachea can not be pulled out after the operation, the breathing support is needed, and the matched single-cavity tracheal catheter needs to be cleaned by subglottic secretions, 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 drop out of 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 catheter 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 mucosa at the opening of a bronchus can be damaged, bleeding can be caused, and even 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, expand and clean the side lung of an operation in a thoracic operation and does not need to be drawn out and inserted into a tube to operate when respiratory support needs to be kept after the operation is finished is clinically lacked.

The end hole 20 of the catheter body is positioned at the end of the head end of the catheter body 1, the end hole 20 of the catheter body is communicated with the catheter body 1, and gas entering and exiting the catheter body 1 can replace the gas in the lung through the end hole 20 of the catheter body in a respiratory support process.
The air bag vacant area does not penetrate through the tube wall of the side of the catheter body 1, namely, the air in the catheter body 1 can not be exhausted through the air bag vacant area. In order to realize the sealing effect during ventilation, a catheter sealing bag 2 needs to be arranged at the head end of the catheter body 1, and the catheter sealing bag 2 is wrapped on the outer wall of the catheter body 1. In the embodiment of the invention, the length direction of the catheter sealing bag 2 is consistent with the length direction of the catheter body 1, but the length of the catheter sealing bag 2 is far less than the length of the catheter body 1, and is generally 3cm-5cm. In order not to influence the function of the air bag vacancy area, the corresponding outer wall of the air bag vacancy area is wrapped by the catheter sealing bag 2 at the head of the catheter body 1, the air bag vacancy area is located between two ends of the catheter sealing bag 2, namely the outer ring of the air bag vacancy area is the catheter sealing bag 2 wrapping the catheter body 1, the lower edge of the catheter sealing bag 2 is located between the air bag vacancy area and a hole 20 at the end part of the catheter body, and the air bag vacancy area is located between the upper edge of the catheter sealing bag 2 and the lower edge of the catheter sealing bag 2.
In the embodiment of the invention, the air bag vacant area is communicated with the operation lung operation tube 13 through the catheter side hole 3, and the operation on the operation lung can be performed by matching the operation lung operation tube 13 with the air bag vacant area, including the steps of shrinking the lung, blowing the lung, supplying oxygen or cleaning secretion, wherein the shrinking the lung specifically means that the air in the operation lung is pumped out, so that the operation lung is shrunk, and the space of the chest cavity of the operation side is vacated to facilitate the operation; the lung bulging specifically means that external air is sent into the lung at the side of the operation to re-expand the collapsed lung; the secretion cleaning operation specifically refers to sucking the secretion generated in the operation process out of the body, reducing atelectasis caused by the blockage of small airways (clinically, usually, small bronchioles with the inner diameter of less than 2 mm) by the secretion, and reducing lung infection caused by the secretion.
When the operation side lung is a left lung during specific use, the right lung is required to support breathing in the operation, 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 sealing bag 2 is positioned on the right side of the carina, namely the front half part of the catheter sealing bag 2 is positioned in the opening of a right bronchus, the rear half part (including an air bag vacancy area) of the catheter sealing bag 2 is positioned behind the carina in the trachea, and the air bag vacancy area is positioned behind the left side of the carina in the main trachea at the moment, so that the air bag vacancy area is opposite to the opening of the left bronchus. The catheter sealing bag 2 is filled with a proper amount of gas, the catheter sealing bag 2 is expanded, the right bronchus is blocked by the front half part of the catheter sealing bag 2, and the main bronchus is blocked by the rear half part of the catheter sealing bag 2. The catheter body 1 can breathe the right lung through the catheter body end hole 20 and support, and at the same time, can manage the left lung through the operation lung operation tube 13 and the balloon vacancy area, as follows: the left lung is communicated with the outside through the operation lung operation tube 13 and the air bag empty area, so that the air in the left lung can be discharged, and the left lung can be deflated; or the operation such as secretion cleaning and the like can be realized when the operation lung operation tube 13 and the air bag vacancy area are connected with external negative pressure suction equipment; when air can be fed into the left lung through the operation lung operation tube 13 and the air bag empty area, the left lung with shrivelled can be expanded, namely, the lung bulging operation can be realized; pure oxygen can be fed into the left lung through the operation lung operation tube 13 and the air bag vacancy area, and auxiliary oxygen supply support can be realized. In specific implementation, the front half part of the catheter sealing balloon 2 is used for guiding the part of the catheter sealing balloon 2, which is adjacent to the end hole 20 of the catheter body, and the rear half part of the catheter sealing balloon 2 is used for guiding the part of the catheter sealing balloon 2, which is far away from the end hole 20 of the catheter body.
Before the operation is started, the catheter breathing connector at the tail of the catheter body 1 is connected with a breathing machine/an anesthesia machine, and the breathing machine/the anesthesia machine carries out breathing support on the right lung to ensure oxygen supply of a patient. Simultaneously, the left bronchus of the left lung is communicated with the outside by utilizing the matching of the air bag empty area and the operation lung operation tube 13, so that the gas in the left lung is discharged, the left lung is shriveled, and the left chest cavity has enough operation space. If necessary, the tail part of the operation lung operation tube 13 is connected with a negative pressure suction device to implement negative pressure suction, so that the gas in the left lung is discharged. When the lung compliance of a COPD patient is poor, negative pressure suction is often needed to assist the intra-operative pulmonary gas discharge.
When the operation is started, the catheter body 1 supports the single lung breathing of the right lung through the end hole 20 of the catheter body, performs the single lung ventilation of the right lung and ensures the oxygen supply of the patient. And the left lung in the shrivelled state avoids damaging the left lung when the chest wall is cut, and meanwhile, the operation side chest cavity has enough space to facilitate the operation in the operation, thereby reducing the operation difficulty and improving the operation safety.
For some patients with poor lung exchange function, the oxygen supply for the right lung for ventilation alone may be insufficient, and the pure right lung ventilation in the operation may cause hypoxemia of the patient, so that the operation risk of the patient is increased, and the patient is not good. At this moment, can be through operation lung operation tube 13 afterbody connection oxygen, to the left lung low pressure oxygen suppliment of operation side, be full of oxygen in the small gas passage that makes the left lung collapse, oxygen can exchange with blood to increase patient's oxygen and supply, improve hypoxemia.
When secretion needs to be sucked and cleaned by the negative pressure of the left lung in the operation, the tail end of the operation lung operation tube 13 is only required to be connected with the negative pressure device. During the operation, operation side lung is at the upside, and non-operation side is located the downside, and when having the secretion in the operation lung, under the action of gravity, the secretion can flow to operation collateral branch trachea oral area, accomodates back rethread operation lung control tube 13 to the secretion through lateral surface recess 4 and can attract the clearance to the secretion. When necessary, a small amount of physiological saline can be injected into the bronchus of the operation side lung through the operation lung operation tube 13, the endocrine of the bronchus of the operation side lung is diluted, and then the negative pressure is sucked and discharged, so that the negative pressure cleaning effect is ensured. In principle, the normal saline for each flushing is controlled within 20ml, so that the condition that the normal saline is excessively absorbed by the lung and the active substances distributed on the inner surface of the alveoli are reduced to cause postoperative atelectasis is avoided. The operation of injecting physiological saline into the operation side lung through the operation lung operation tube 13 and the air bag vacancy area is the same as the operation of flushing and sucking the bronchus anastomotic stoma by using the physiological saline when the transplantation lung anastomosis in the existing lung transplantation operation is completed, which is known to those skilled in the art specifically and is not repeated herein.
When the left lung operation is finished, the tightness of the left lung cutting anastomosis stoma needs to be detected, and the left lung can be inflated by inflating gas through the operation lung operation tube 13 and the air bag vacancy area, so that the lung bulging operation is realized. If the cutting anastomotic stoma leaks air, the left lung is exhausted through the surgical lung operation tube 13 again, so that the left lung is shrivelled, the cutting and suturing part of the leaked air is conveniently reinforced and repaired until the cutting anastomotic stoma is satisfactorily detected, and the surgical operation on the left lung can be completed.
After the operation of the left lung is completed, the ventilation of the two lungs is timely recovered, at the moment, the left lung is firstly sucked and cleaned by negative pressure through the operation lung operation tube 13, the left lung is inflated after the secretion is cleaned, so that the left lung is expanded and re-expanded (the lung re-expanded refers to the situation that the lung is inflated again in the lung tissue), then the catheter body 1 is retreated by 3cm-5cm, and the catheter sealing bag 2 is retreated to enter the main trachea. The air bag empty area corresponds to the side wall of the main air pipe and can form a blind hole state. The breathing machine/anesthesia machine can be connected and matched with the catheter body 1 through the catheter breathing connector at the tail end of the catheter body 1, so that the support of ventilation of the two lungs can be realized. On one hand, the irritation of the catheter sealing bag 2 to the carina is reduced, and the cardiovascular reaction is reduced; on the other hand, the time for collapsing the operation lung can be reduced as much as possible, the reduction of the surface active substances of the alveoli is reduced, and the probability of atelectasis caused by the reduction of the surface active substances of the alveoli is reduced.
Similarly, when the operation lung is the right lung, the left lung is required to support respiration during the operation, the catheter body 1 is inserted into the main trachea by adopting a common technical means after anesthesia, the depth and the position of the catheter body 1 are adjusted, the catheter sealing bag 2 is positioned on the left side of the carina, namely, the front half part of the catheter sealing bag 2 is positioned in the opening of the left bronchus, the rear half part (including the air bag vacancy area) of the catheter sealing bag 2 is positioned behind the carina in the trachea, and the air bag vacancy area is positioned behind the right side of the carina in the main trachea, so that the air bag vacancy area is opposite to the opening of the right bronchus. The catheter sealing bag 2 is filled with a proper amount of gas, the catheter sealing bag 2 is expanded, the left bronchus is blocked by the front half part of the catheter sealing bag 2, and the main bronchus is blocked by the rear half part of the catheter sealing bag 2. The pipe body 1 can breathe through pipe body tip hole 20 and support to the left lung, simultaneously, can manage the right lung through operation lung control tube 13 and gasbag vacancy district, and the process of specific operation is similar with when the operation of left side, and this is no longer repeated here.
Under some special conditions, when the operations on the two lungs are required in sequence, the catheter body 1 is positioned according to the method, so that the front half part of the catheter sealing bag 2 enters the bronchial opening of the lung at the side A, and the vacant area of the air bag is over against the bronchial opening of the lung at the side B until the lung at the side B finishes the required operations. After the lung operation on the side B is finished, the catheter body 1 is retreated by 3cm-5cm, so that the catheter sealing bag 2 is retreated into the main trachea. And the catheter body 1 is positioned again, so that the front half part of the catheter sealing bag 2 enters the bronchial opening of the lung at the side B, and the vacant area of the catheter is opposite to the bronchial opening of the lung at the side A until the operation of the lung at the side A is completed. Thus, bilateral lung surgery can be completed in sequence without replacing airway management tools. The side a lung is one of the left or right lung, and the side B lung is the other lung corresponding to the side a lung. Of course, when the above-mentioned a-side lung and B-side lung are converted, the operations of the above-mentioned sealing inspection of some cutting anastomotic openings, cleaning of secretions and the like also need to be performed, and specific operation processes may refer to the above description and are not described herein again.
In some patients with extremely poor lung function, when the lung function is insufficient to support the spontaneous respiration of the patient after the operation (the judgment standard is that the arterial oxygenation index of the patient is lower than 250 mmhg), the tracheal catheter cannot be pulled out after the operation, and the catheter body 1 is only required to be retracted by 3cm-5cm, so that the catheter sealing bag 2 is retracted into the main trachea. The air bag vacant area corresponds to the side wall of the main air pipe to form a blind hole state. The breathing machine/anesthesia machine can realize the ventilation of the two lungs through the cooperation of the catheter breathing connector at the tail end of the catheter body 1 and the catheter body 1, and the breathing management after the operation is carried out.
