Description

{Endotracheal tube}

TECHNICAL FIELD The present invention relates to intracorporeal tubes, and more particularly to intracoracal tubes in which a detection ring surrounding a tubular body is disposed so as to grasp the substance passing therethrough.

Endotracheal intubation is the insertion of an endotracheal tube to secure airway. Intubation is used in cases where respiratory disturbance due to trauma, foreign body, central nervous system diseases, airway obstruction, discharge of secretions, and decrease in respiratory function is needed and artificial respiration is needed. It is necessary to maintain airway openness, Facilitates secretion, oxygenation, and ventilation.

The intubation of the trachea involves oral intubation via the oral cavity and intranasal intubation via the nasal cavity.

Oral vascular endotracheal intubation through the oral cavity of the patient can be performed promptly, avoiding nasal complications associated with nasal insertion, and allowing the use of large caliber tubes, allowing air to flow smoothly and ease the removal of secretions. However, careful nursing intervention is needed to prevent unstable, uncomfortable, unintentional extubation of patients who can not move their neck, difficulty in oral care, communication and swallowing ability It is lost, the vomiting reflex is stimulated, and the fixing tape may loosen by the secretion of saliva.

Nasal dural intubation through the nasal cavity is less likely to cause patient discomfort and anxiety once inserted, facilitates oral care, less complications of oral cavity, less vomiting and irritation, communication, You can swallow a small amount of solution and use less tube, so less damage to the larynx. However, it is more difficult than oral insertion, can cause non-bleeding during insertion, can produce purulent secretions or sinusitis within a few days, and requires relatively few tubes to be used for non-passage, resulting in increased airway resistance, It may be long and suffocated.

On the other hand, if the depth of the intubation tube is too shallow, it is likely to be easily dislodged. If the intubation is too deep, complications such as tension pneumothorax on the ipsilateral side, atelectasis on the opposite side, and hypoxia are likely to occur. Therefore, the position of an appropriate endotracheal tube is recognized as an important problem.

In addition, if it is possible to identify what kind of substance is passing through the tube in the organ, such as food or secretion, and the amount of the substance, it is possible to grasp the condition of the patient and help the treatment.

Therefore, in order to improve the airway maintenance and treatment effect through intubation, it is necessary to know what kind of substance and quantity of the substance through the endotracheal tube during intubation, and in addition, It is necessary to set the position of the intubation tube to an optimal position.

Therefore, it is an object of the present invention to provide an intracavital tube in which a detection ring is disposed so as to grasp the quantity and quantity of substances passing through the intracoracal tube.

In order to achieve the above object, the intracoracal tube according to the present invention comprises a tubular body into which a distal end portion is inserted into an organs, an inflatable expandable portion surrounding the tubular body, a detection ring surrounding the tubular body, And an expansion tube into which air is infused to inflate the inflating portion.

The sensing ring may be made of a material selected from the group consisting of stainless steel, cobalt-chrome alloy, titanium, titanium alloy, and nickel-titanium shape memory alloys. Or the like.

And, the detection ring may include at least one of a chip and a sensor for state recognition or treatment of a patient.

According to another aspect of the present invention, there is provided a method for manufacturing an endotracheal tube, comprising the steps of: providing a hollow tubular main body; disposing a balloon expandable portion to surround one side of the tubular main body; And disposing the detection ring so as to surround the tubular body between the distal end of the tubular body inserted into the engine and the balloon-shaped expandable portion.

According to the present invention, a detection ring is disposed between the distal end portion of the tubular body and the inflated bulged portion so as to surround the tubular body, and substances such as food, secretion, etc. passing through the tubular body can be confirmed through the external medical device. Accordingly, it is possible to grasp the condition of the patient more accurately and to help the patient to be treated. In addition, the balloon expanding portion may be formed of a soft material to reduce the inconvenience and the foreign matter feeling due to the insertion of the intracorporeal tube.

Hereinafter, the present invention will be described in detail with reference to the drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view showing the outline of an endotracheal tube according to an embodiment of the present invention; FIG.

Referring to FIG. 1, intracorporeal tube 100 includes a tubular body 110 having a distal end 111 and a distal end 113. The tubular body 110 is long and hollow and curved so that gas can flow and the tip 111 of the tubular body 110 can be inserted into the patient's airway and attached to the end portion 113, The connector 150 is mounted.

In the tubular body 110, a balloon expander 130 is disposed to surround the tubular body 110. The inflatable bulge 130 is connected to the inflation tube 120 and is inflatable by the air injected through the inflation tube 120. Accordingly, after the tubular body 110 is inserted into the patient's airway, the inflated bulge 130 is inflated by the air injected through the inflation tube 120, and pressure is applied to the patient's organ wall, And gastric juice can be prevented from being sucked into the lungs. .

A pilot balloon 123 disposed at the distal end of the expansion tube 120 checks whether the expansion system of the balloon expander 130 is abnormal or not and determines how much air is contained in the balloon expander 130 So that they can be tactile.

The endotracheal tube 100 having such a configuration is inserted into the organ through the mouth or nose of the patient, and then fixed using a tape or a fixing device.

Fig. 2 is an enlarged view of a tip end portion of the tubular main body in the endotracheal tube of Fig. 1, and Fig. 3 is a side view of Fig.

2 and 3, a detection ring 150 formed of a metal material is inserted between the distal end portion 111 of the tubular body 110 and the balloon expandable portion 130 in the endotracheal tube 100 according to the present invention. And is disposed so as to surround the tubular body 110.

The detection ring 150 may be disposed at any position between the tip end 111 and the inflatable bulge 130 and between the inflatable bulge 130 and the inflation tube 120, .

The detection ring 150 can identify the substance passing through the tubular body 110, such as food or secretion, using the external medical device, and confirm the transfer of the substance. That is, a substance passing through the tubular body 110 can be identified through X-ray, ultrasound, computed tomography, or other devices capable of penetrating the human body, thereby allowing a more accurate grasp of the patient's condition.

Further, by grasping the position of the detection ring 150, the intubation tube 100 can be inserted to an ideal position and can be moved to an ideal position.

In other words, if the depth of the intracoronary tube 100 is too shallow, the intubation is easy. If the intubation is too deep, various complications such as a tension pneumothorax on the ipsilateral side, The position of the ring 150 can be grasped and the intubation position of the intubation tube 100 can be set to the optimum position. It is generally known that the end of the endo-tracheal tube 100 is ideally located in the middle of the trachea.

The detection ring 150 may be formed of a metal material. For example, stainless steel, cobalt-chrome alloy, titanium, titanium alloy or nickel-titanium shape memory alloys, The detection ring 150 can be formed of a harmless metal material.

In addition, the detection ring 150 may include a chip or a sensor that can be used for the purpose of grasping the state of a patient or for other therapeutic purposes.

4 is a cross-sectional view of the tubular main body in the case of cutting in the direction of X-X 'in Fig. 3 to Fig. 3;

Referring to FIG. 4, the sensing ring 150 is disposed to surround the tubular body 110, which, when placed outside the tubular body 110, may cause trauma to the patient during intubation. Therefore, it is preferable that the detection ring 150 is inserted into the tubular body 110 and installed integrally. However, in addition to the position shown in FIG. 4, the position where the detection ring 150 is disposed may vary depending on the use environment.

Meanwhile, the intracorporeal tube 100 can be manufactured in various sizes. That is, the sizes of the throat are different according to the age and sex of a person. The size of the intracorporeal tube 100 can be variously sized based on the inner diameter of the tubular body 110. The size of the endotracheal tube 100 may be determined according to the formula or according to the clinical judgment of a doctor.

In addition, the balloon expandable portion 130 can be formed from a variety of soft materials commonly used in medical tubes. For example, it may be formed of one or more selected from the group consisting of elastomer, silicone and soft resin.

By forming the inflatable expanding portion 130 as described above, it is possible to reduce the inconvenience and foreign matter caused by the intrusion of the intracorporeal tube, and to minimize the complication caused by intubation.

Intra-tracheal tube 100 intubated with an organ can be removed, for example, when the patient can breathe on his own or can discharge sputum himself. In other words, when the baseline condition needed to be improved, there is no new reason to keep the artificial airway and hemodynamically stabilized, when the patient can remove the secretion by himself, In cases such as when the volume is small, when artificial ventilation support is no longer needed, the intracorporeal tube inserted into the patient can be removed.

It is to be noted that the present invention is not limited to the configuration and the method of the embodiments described above, but the embodiments may be modified so that all or some of the embodiments are selectively As shown in FIG.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It should be understood that various modifications may be made by those skilled in the art without departing from the spirit and scope of the present invention.
