Description
Technical Field
The invention belongs to the technical field of tracheal tubes used in the operation process, and particularly relates to a laryngeal mask tracheal tube combined tube.
Background
Currently, endotracheal tubes are widely used for clinical anesthesia, ensuring that the patient breathes normally under anesthesia, and are commonly used in long-term surgical procedures. The patient is in an unconscious state in the anesthesia process, the stimulation of the tracheal catheter to the patient can not be generated, but after the anesthesia is finished, the tracheal catheter stimulates the airway when the patient is ready to wake, so that the patient choking cough is generated (the tracheal catheter can be pulled out after the patient is required to wake), and the probability of cardiovascular and cerebrovascular accidents is increased for the elderly hypertensive patient. Especially in neurosurgery patients, ophthalmic patients and the like, in the process of tube drawing after operation, choking cough increases intracranial pressure and intraocular pressure, thereby increasing accidents such as cerebral hemorrhage, eye content injury and the like, and further increasing the probability of postoperative complications of patients.
During the extraction period (peri-extraction period) of the tracheal catheter in the general anesthesia recovery period of craniotomy, along with the reduction of anesthesia, due to pain, sputum suction and stimulation of the tracheal catheter, cardiovascular reactions such as blood pressure rise, heart rate acceleration and the like can occur in the peri-extraction period, and respiratory reactions such as breath hold, cough choking, laryngeal bronchospasm and the like can be induced. Thus, an ideal neurosurgical anesthetic wakeup should transition smoothly without significant metabolic and circulatory fluctuations. How to regulate and control the stress response moderately in the peri-extraction period of craniotomy and maintain stable hemodynamics, so that patients can pass through the peri-extraction period smoothly and have good prognosis, and the method is a research hot spot of neurosurgery anesthesia.
With the arrival of an aging society, more and more advanced patients can be ventilated if the occurrence rate of choking and cough in the process of drawing a tube after operation is reduced, which is really a matter of benefiting the country and the people.
The existing laryngeal mask is widely applied to clinic at present, is mainly suitable for supraglottic ventilation of short and small operations, and has the advantage of good ventilation. And because the utility model is a ventilation tool on the glottis, the occurrence of choking is reduced. Laryngeal masks are not applicable to long term surgery and are particularly inapplicable to prone patients.

Detailed Description
Example 1: the laryngeal mask endotracheal tube combination tube shown in figures 1 and 2 has a tubular configuration with a tracheal body 1, a lower tracheal port 6 which can be inserted into the body, and an upper tracheal port which can be connected to an existing inflation device, such as a balloon or other existing inflation device.
The outer side wall near the lower port of the tracheal body 1 is provided with a sealed spherical small air bag 2, the spherical small air bag 2 is communicated with a small air bag inflation and deflation pipe 3, the tail end of the small air bag inflation and deflation pipe 3 is connected with an inflation and deflation device, for example, an inflation small air bag is connected, a unidirectional air inlet valve is arranged on the inflation small air bag, and a deflation valve is arranged on the small air bag inflation and deflation pipe 3. In fig. 1, it can be seen that the balloon-shaped balloon 2 can be inflated through the balloon inflation/deflation line 3, so that the balloon-shaped balloon 2 is inflated into a sphere, and at this time, the laryngeal mask-shaped balloon 4 has no air pressure therein and is not effective in a contracted state. The respiratory tract of the patient can be sealed by using the spherical small air bag 2, so that the patient under anesthesia can be subjected to auxiliary breathing by using external force to blow air.
A laryngeal mask-shaped large balloon 4 is arranged on the tracheal body 1 near the outer side of the spherical small balloon 2. As can be seen in fig. 2, the laryngeal mask shaped big air bag 4 is an annular air bag, the width of the upper end of the annular air bag is larger than that of the lower end of the annular air bag, the central area of the annular air bag is a laryngeal mask cavity, the laryngeal mask cavity is arranged at the bottom of the laryngeal mask cavity and is provided with a laryngeal mask cavity sealing bottom layer 7, the laryngeal mask shaped big air bag 4 is communicated with a big air bag inflation and deflation pipe 5, and the tail end of the big air bag inflation and deflation pipe 5 is connected with an inflation and deflation device. For example, an inflatable small balloon is connected, a one-way air inlet valve is arranged on the laryngeal mask-shaped large balloon 4, and a deflation valve is arranged on the large balloon inflation and deflation pipe 5. The laryngeal mask shaped big air bag 4 adopts the above structure to draw out the spherical small air bag 2 when the patient is not awake, pull out the tracheal catheter, the laryngeal mask shaped big air bag 4 is inflated to block the esophagus and the oral cavity outlet, and can supply oxygen for the patient when ventilation, and the stimulation of the tracheal catheter in the trachea is reduced, and the occurrence of choking cough is reduced.
As can be seen in fig. 2, the wide end of the upper end of the laryngeal mask shaped large air bag 4 is fixed on the side wall of the air pipe body 1, the tip end of the lower end is a free end, and the length of the tip end part of the lower end of the laryngeal mask shaped large air bag 4 after inflation is longer than that of the lower end of the laryngeal mask shaped large air bag 6, so that the lower end 6 of the air pipe is positioned in the laryngeal mask cavity in the center of the laryngeal mask shaped large air bag 4. The structural design of the laryngeal mask-shaped large air bag 4 can be used for blocking esophagus and oral cavity after the laryngeal mask-shaped large air bag is inflated, meanwhile, the lower tracheal port 6 is located at the inner side of the laryngeal mask cavity, the laryngeal mask cavity and the respiratory tract are in a communicating state, at the moment, the stimulation of the tracheal catheter in the trachea can be reduced, the occurrence of choking is reduced, and the laryngeal mask-shaped large air bag has the advantage of dual purposes.
In order to achieve better matching effect of the laryngeal mask shaped large air bag 4 and the spherical small air bag 2, a part of the laryngeal mask cavity closed bottom layer 7 is attached to one side face of the spherical small air bag 2 into a whole. The lower tracheal port 6 can be a bevel, and the laryngeal mask-shaped large air bag 4 is positioned on one side of the bottom surface of the bevel, so that the lower tracheal port 6 can be ensured to ventilate sideways.
