Hereinafter, with reference to the accompanying drawings will be described in detail a first embodiment of the endotracheal tube of the present invention.

1 is a perspective view of an endotracheal tube in accordance with the present invention.

As shown, the esophageal tracheal tube according to the invention is attached to the tracheal tube outer surface at a position slightly above the elongated soft tracheal tube 10, the distal end 11 of the tracheal tube 10 of a predetermined diameter. Distal air sac 20, a plurality of ventilating openings 15 perforated in the tracheal tube 10 just above the terminal air sac 20, disposed in a predetermined position above the ventilating opening 15 to the outer surface of the tracheal tube Attached to the intermediate bladder 30, the indicator 40 displayed on the outer surface of the tracheal tube at a predetermined position above the intermediate bladder 30, and connected to the terminal bladder 20 to function to expand / contract the terminal bladder A pilot balloon 22 for the terminal vesicle, and a pilot balloon 32 for the middle vesicle, which is connected to the intermediate vesicle 30 and functions to expand / contract the middle vesicle.

The terminal bladder 20 and the pilot balloon 22 and the intermediate bladder 30 and the pilot balloon 32 are connected by soft expansion tubes 24, respectively, and the expansion tube 24 is a tracheal tube ( 10) Although it may be disposed outside, it is preferable to be configured to connect the bladder and the pilot balloon through the tracheal tube (10), respectively. In addition, the distal end 11 of the tracheal tube 10 is blocked and prevents the anesthesia gas from entering the esophagus during use, and is made of a bevel shape to facilitate insertion into the esophagus 60, the other end 13 is open have. In use, the other end 13 is connected to the necessary equipment such as anesthesia, respirator, or oxygen supply.

As will be described later, when the tracheal tube 10 according to the present invention is inserted into the oral cavity of the rabbit, the bladder 20 and 30 attached to the tracheal tube 10 outside by the rabbit incisor 50 are not damaged. The material of the bladder is preferably made of a material that is tough and easy to expand / contract. In addition, the material of the tracheal tube 10 is sterilizable, it is preferable to configure the reusable silicon (autoclavable silicon) about 10 to 20 times. The indicator table 40 is preferably displayed in a solid line between the intermediate bladder 30 and the other end 13, and serves to indicate that the intubated tube is inserted to an appropriate length when the tube is inserted.

In addition, between the distal end 11 and the other end 13, it is preferable that a scale table (not shown), which is expressed in cm, is displayed.

It will be described with reference to Figure 2 how to intubate the tracheal tube according to the invention configured as described above to the trachea of rabbits.

Inhalation anesthesia by forced ventilation method using the tracheal tube according to the present invention is as follows.

First, the tracheal tube 10 is inserted into the esophagus 60 through the throat of the rabbit by the blind eye. In general, when the tracheal tube 10 is inserted into the esophagus 10, the case is rarely inserted into the airway 70. This is because the anatomical structure is more likely to be naturally inserted into the esophagus than the airways. At this time, in order to insert the tracheal tube so that the ventilator 15 is mounted from the throat to the airway entrance, it is preferable that the indicator 40 is inserted until it matches the incisor 50 of the rabbit. When the insertion is completed, using the pilot balloon (22, 32) to inflate the terminal bladder 20 and the intermediate bladder 30 to the appropriate pressure. At this time, the terminal bladder 20 is inserted into the esophagus 60, the intermediate bladder 30 is inserted into the rabbit's oral cavity, and the terminal bladder 20 is in close contact with the inner surface of the esophagus 60 in an inflated state. It is preferable that the gas does not leak out of the oral cavity, and the mid air sac 30 is also in close contact with the inner surface of the rabbit's mouth in an inflated state so that the gas does not leak.

In this state, it is possible to check whether the ventilator 15 is located at the throat, which is an appropriate position, by using capnography, which shows the partial pressure of carbon dioxide as a numerical value and a graph. When the ventilator 15 is located at an appropriate position, the breathing gas is normally entered through the ventilator, so that the carbon dioxide emitted from the lungs during respiration can be confirmed using capnography. In other words, it is possible to simply check whether the ventilating opening 15 of the tube 10 is located in the throat, which is an appropriate position.

When it is confirmed that the tube 10 is inserted into the esophagus 60 in place, the anesthesia 80 is connected to the other end 13 of the tube to send an anesthetic gas. Anesthesia gas is discharged to the lungs through the airway while being discharged in the direction of the arrow (A) through the vent hole (15) of the tracheal tube (10), ventilating the lungs and through the endotracheal tube through the esophageal trachea tube through the anesthesia Discharged. At this time, since the bladder (20, 30) is in close contact with the esophagus and the oral cavity to maintain a state to prevent gas leakage, the anesthesia gas is completely prevented from leaking out of the stomach (stomach) or the oral cavity.

In the above description, the case of anesthesia through anesthesia has been described as an example, but the same applies to an emergency situation in which oxygen supply and controlled ventilation are required. In this case, since the tracheal tube can be inserted into the position much faster than the conventional method, the oxygen supply can be performed quickly, smoothly, and safely in an emergency situation requiring oxygen supply.

Next, a second embodiment of the endotracheal tube of the present invention will be described. 3 is a perspective view of a second embodiment of a tracheal tube according to the present invention; As shown, the esophageal tracheal tube according to the present invention is an elongated soft tracheal tube 90 inserted into the esophagus in use, and an expandable meso sac that is attached to the outside of the tracheal tube 90 and injected with gas therein. And a pilot balloon 112 for an intermediate bladder which is connected to the intermediate bladder 110 and expands the intermediate bladder.

At the end of the tracheal tube 90, an end portion 101 is formed in a bevel shape and has a closed distal end portion 100 having an inner diameter that can be in close contact with the inner wall of the esophagus upon insertion. At the other end of the tracheal tube 90, the other end 93 is formed to be exposed outside the mouth and open to the anesthesia. At this time, a plurality of vent holes 95 are perforated in the upper portion of the end contact portion 100. At this time, the distal end 101 is blocked, thereby preventing the anesthesia gas from entering the esophagus during use. The other end 93 is open, so that in use, it is connected to necessary equipment such as anesthesia or oxygen supply.

The intermediate bladder 110 and the pilot balloon 112 are each connected by a soft expansion tube 114. The expansion tube 114 may be disposed outside the tracheal tube 90, but is preferably configured to connect the intermediate bladder 110 and the pilot balloon 112 through the tracheal tube 90, respectively. At this time, the material of the intermediate bladder 110, as in the first embodiment, when the tracheal tube 90 is inserted into the oral cavity of the rabbit, the material is tough and inflated / contracted so as not to be damaged by the incisor 50 of the rabbit. It is made of easy material. Also, the material of the tracheal tube 90 is also the same as in the first embodiment.

On the surface between the other end 93 and the intermediate bladder 110, the indicator 120 is indicated by a solid line. The indicator table 120 functions to indicate that the endotracheal tube 90 is inserted to an appropriate length when the endotracheal tube 90 is inserted.

In addition, between the distal end 101 and the other end 93, it is preferable that a scale table (not shown), which is expressed in cm, is displayed.

Indicator 120 is located in the oral cavity of the intermediate bladder 110 when the tracheal tube 90 is inserted in the oral cavity of the animal so as to coincide with the incision 50 of the animal. It is completely adhered to. In addition, the end contact portion 100 is positioned in the animal esophagus when the intubation of the tracheal tube 90 so that the indicator 120 is aligned with the incision 50 of the animal so that the esophagus is in close contact with the esophagus.

Ventilation port 95 is mounted from the throat to the airway entrance during intubation of tracheal tube 90.

Since the use of the endotracheal tube as described above is almost similar to the first embodiment, a detailed description thereof will be omitted.

The present invention has been described with reference to the preferred embodiments shown in the drawings, and those skilled in the art will understand that various modifications are possible therefrom, and in accordance with the present invention, the distal end is blocked and into one tracheal tube. It is to be understood that all inhalation anesthesia tracheal tubes are included within the scope of the present invention. Accordingly, the true scope of protection of the invention should be defined by the appended claims.

As described above, according to the first and second embodiments of the inhalation anesthesia endobronchial tube according to the present invention configured as described above, the tube can be quickly and safely using the present invention even in a situation where the endotracheal intubation of the conventional method is difficult. And easily inserted into the esophagus can be easily performed inhalation anesthesia through a controlled ventilation. Of course, anesthesia gas and the like can be completely prevented from leaking out of the esophagus or oral cavity to ensure safety. Because of the ease of use and excellent safety benefits can be greatly utilized in the field of laboratory animal anesthesia, it can also contribute to the activation of animal experiments.
