Description

Large balloon small inner diameter anesthesia endotracheal tube

【Technical field】

The utility model belongs to the technical field of medical devices, in particular to a large-sac small inner-diameter anesthesia trachea tube dedicated for maintaining breathing in oral and pharyngeal operations such as glottis and epiglottis.

【Background technique】

At present, there are many types and models of tracheal tubes, which are widely used in clinical medicine, and are very common in emergency rooms, operating rooms and intensive care units. The use of the tracheal tube ensures the normal ventilation of the lungs and avoids the life-threatening of patients due to airway obstruction, respiratory failure or hypoxia.

However, in the anesthesia of some specialized operations, for example, when the anesthesia tracheal tube is used for operations on the epiglottis and glottis, because the existing anesthesia tracheal tube is too thick and the air bag is too small, in the epiglottis, glottis and other parts, the too thick The endotracheal tube will form a certain obstacle to the operation, obstructing the surgeon's surgical field of view, sometimes prolonging the operation time, and even causing incomplete treatment of the surgical site; too small air bag will affect the effect of the anesthesia endotracheal tube; In addition, during the operation, surgical instruments, such as scalpels, surgical scissors, surgical electric knife, etc., may damage the anesthesia endotracheal tube. If the anesthesia endotracheal tube is damaged during the operation, it will cause many unnecessary troubles. If it is replaced in time, if it cannot be found in time, it will affect the smooth progress of the operation, and seriously, it will cause danger to the patient's life.

【Content of utility model】

The purpose of the utility model is to overcome the deficiencies of the prior art, to provide a device that does not affect the surgical field of view of the chief surgeon, can reduce the damage rate of the tracheal tube, and has a functional Prominent large balloon small bore anesthesia endotracheal tube.

The utility model large sac small inner diameter anesthesia tracheal catheter is composed of a tracheal catheter, a catheter front end opening, a catheter front side opening, an air bag, an air bag flushing and deflation opening, an inflation and deflation valve, an inflation and deflation valve connecting tube, and an outlet at the catheter tail end. The opening at the front end of the catheter is a slope-shaped opening, and there is a side opening at the front end of the catheter under the raised end of the opening at the front end of the catheter. The air bag flushing and deflation opening, the air bag flushing and deflation opening is connected with the connection tube of the inflation and deflation valve, and the inflation and deflation valve connection tube runs along the inner wall of the endotracheal catheter for a period of time under the air bag flushing and deflation opening, and then in the middle and rear section of the endotracheal catheter position stretches out the endotracheal catheter, the other end of which is connected to the inflation and deflation valve, and the other end of the endotracheal catheter is the outlet of the catheter tail end. The technical feature of the utility model is that the inner diameter of the air bag is 25 to 40 millimeters (mm), and the The inner diameter of the endotracheal tube 1 is 4.5-6.5 millimeters (mm).

The above-mentioned airbag adopts thin-wall technology and is made of medical soft rubber material, which can produce low-pressure effect and reduce and avoid airway damage of patients.

The small inner diameter anesthesia endotracheal catheter of the utility model adopts a small inner diameter endotracheal catheter, and the enlarged air bag improves the functional effect of the anesthesia endotracheal catheter in surgery, and not only makes the anesthesia endotracheal catheter more effective in ENT and stomatology operations, such as vocal cords During the operation of polypectomy, the surgical field of view is broadened, and the obstacles in the treatment of the epiglottis and glottis are reduced, and the small inner diameter of the large balloon makes the effect of the tracheal tube more obvious, making the operation smooth and the operation site treated more thoroughly . In addition, the use of large balloon and small inner diameter anesthesia endotracheal tube also shortens the operation time, reduces the risk of operation, reduces the damage of anesthesia endotracheal tube caused by surgical instruments, makes the medical effect better, and satisfies doctors and patients.
