Description

Reinforced bronchial catheter with plugging and hemostasis functions
Technical Field
The invention belongs to the technical field of bronchial catheters, and particularly relates to a reinforced bronchial catheter with a plugging and bleeding stopping function.
Background
The trachea cannula is a special trachea catheter which is placed into a trachea or a bronchus through a glottis through an oral cavity or a nasal cavity, provides the best conditions for unobstructed respiratory tract, ventilation and oxygen supply, respiratory tract suction and the like, is an important measure for rescuing patients with respiratory dysfunction, and is mainly suitable for rapidly establishing an artificial respiration channel to maintain patients with unobstructed airways during clinical anesthesia, emergency treatment and resuscitation.
Pulmonary nodules, pulmonary infection and the like need to be diagnosed by a bronchofiberscope, but the painless popularization rate is low, the development is limited, and the method is mainly related to certain defects of the current anesthesia method.
Currently, there are three main ways of painless bronchofiberscope anesthesia and ventilation:
1. intubating-free general anesthesia for keeping spontaneous respiration
The advantages are that: simple operation and quick revival.
The disadvantages are as follows: hypoxemia caused by respiratory depression, glossoptosis and the like is easy to occur, and the safety is not high.
2. Laryngeal mask general anesthesia
The advantages are that: can effectively prevent hypoxemia caused by respiratory depression, glossoptosis and the like which may occur in general anesthesia.
The disadvantages are that: when major bleeding occurs in the air passage, the ventilation efficiency is reduced due to the rise of the air passage pressure, effective lung isolation cannot be carried out, and the rescue opportunity can be delayed by temporarily replacing the tracheal catheter.
3. General anesthesia of trachea cannula
The advantages are that: can safely and effectively maintain oxygen supply, and can supply oxygen to healthy side lungs through the tracheal catheter after the plugging device is placed in the case of sudden heavy bleeding, thereby ensuring the oxygen supply.
The disadvantages are that: conventional endotracheal intubation stimulates more, requires greater depth of anesthesia, and may result in increased recovery time and reduced comfort over previous methods. When sudden heavy bleeding occurs, the plugging device needs to be temporarily placed, and the rescue opportunity can be delayed.
4. Double-cavity tube general anesthesia
The advantages are that: can effectively isolate the two lungs and can effectively protect the healthy lateral lung when the lung has huge abscess and hemorrhage.
The disadvantages are as follows: the double-cavity tube has a large outer diameter and a small endoscope, so that the under-endoscope diagnosis and treatment are not facilitated through a thick bronchoscope; the double-lumen tracheal intubation has large stimulation, generally needs muscle relaxing medicines, leads to the prolonging of the awakening time and possible damage to the glottis, and has lower comfort compared with the prior method;
in order to solve the above-mentioned problems, a bronchial tube is proposed that can significantly improve the safety of anesthesia.

According to the invention, one end of the guide part 107 is reduced, so that the tracheal catheter can pass through a glottis conveniently, vocal cord injury can be reduced, the tracheal intubation guided by a bronchofiberscope is smoother, and in sudden heavy bleeding, the tapered distal end can be inserted into the distal end of the bronchus, so that the balloon can be opened after the catheter goes deep into the bronchus, the effect of the stopper is exerted to perform compression hemostasis, and the holes on the two sides of the tapered tube are opened to prevent airflow limitation caused by the reduction of the distal end of the catheter, so that the ventilation effect is achieved.
In this embodiment, the first inflation cuff 2 is 0.5-1.5cm in length, the second inflation cuff 3 is 1.0-3.0cm in length, the first inflation cuff 2 is located on the side closer to the guide portion 107, and the second inflation cuff 3 is located on the side away from the guide portion 107. The present invention employs a double cuff design, with the first inflation cuff 2 being about 0.5-1.5cm in length and the second inflation cuff 3 being about 1.0-3.0cm in lengthcmThe condition that half of the cuff is on the bronchus to be blocked and half of the cuff leaks outside due to overlong length of the single cuff to cause insufficient pressure is avoided; when required in the main air passageWhen oxygen is supplied by pressurization, the double air bags are inflated simultaneously, so that the contact area between the air bags and the air pipe can be increased, and the effect of closed ventilation can be achieved by lower pressure.
The spacing between the first inflation cuff 2 of this embodiment 1 and the end of the guide portion 107 is 1.0-4.0mm, and the guide portion 107 of this embodiment 2 is of a tapered tubular structure. The two embodiments can reduce the distance from the far end of the cuff to the tip of the catheter, are favorable for opening the air bag after sudden heavy bleeding is inserted into the bronchus, and play the role of the stopper to perform compression hemostasis.
The first inflatable cuff 2 and the second inflatable cuff 3 of the embodiment are made of transparent silica gel, and are tightly attached to the periphery of the outer wall of the intubation body 1 when not inflated, and are hidden on the tube wall, so that vocal cords are not easily damaged, and the operation of a bronchoscope is not influenced. After inflation, the maximum diameter of the first inflatable cuff is 1.5-2.5cm, which can effectively block the bronchus, and the maximum diameter of the second inflatable cuff is 2.0-4.0cm, which can effectively block the bronchus.
The length of the intubation tube body 1 is 19-41cm, which is larger than the distance from the incisor teeth to the far end of the bronchus, so that the catheter can be ensured to penetrate into the far end of the bronchus to perform plugging hemostasis.
The inner diameter of the inner tube 104 of this embodiment includes the following two embodiments:
example 1: is consistent with common clinical tracheal catheters, including 3.5mm, 4.0mm, 4.5mm, 5.0mm, …, 8.5mm and the like.
