Description

{Endotracheal tube}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an intracorporeal tube, and more particularly, to an intracorporeal tube having an indicator portion capable of grasping the shape, position, and mounting state of the inflated balloon.

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.

Further, adequate air should be injected into the inflation section, such as an inflatable cuff, provided in the endotracheal tube. If air is not sufficiently injected into the cuff, it is not possible to prevent leakage of air from the lungs or suction of the gastric juice into the lungs. Conversely, if excess air is injected into the cuff, the volume and pressure of the balloon-shaped bulge can cause damage to the organ.

Therefore, in order to improve the airway maintenance and treatment effect through intubation, it is necessary to accurately grasp the inflated state of the inflating part such as the cuff during the intubation, and the mounting position.

Accordingly, it is an object of the present invention to provide an intracoracal tube having an indicator for understanding the shape, position, mounting state, and the like of the inflated balloon.

According to an aspect of the present invention for achieving the above object, there is provided an intracoracal tube including a tubular body inserted into an organs, an inflatable inflatable portion surrounding one of the tubular bodies, an inflatable portion for inflating the inflatable inflatable portion, And an indicator part for grasping the shape and mounting position of the balloon-shaped bulged part can be disposed in the balloon-shaped bulged part.

The indicator unit may include first and second indicator units arranged vertically in the longitudinal direction of the balloon expanding unit and third and second indicator units disposed on the left and right to surround the balloon expanding unit along the outer surface of the balloon expanding unit. 4 indicator unit, and the indicator unit may be formed of at least one material selected from the group consisting of a metal material, a polyvinyl chloride (PVC) having a color, and a silicone having a color.

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; Disposing an inflation tube into which air is infused to inflate the inflated portion, and disposing an indicator portion for grasping the shape and mounting position of the inflated inflated portion in the inflated inflated portion.

According to the present invention, an indicator portion is disposed in the balloon-shaped expanding portion to form an inflated form and a position of the balloon-shaped expanding portion. Mounting state, etc. can be grasped through an external device. Thus, the intracoracal tube can be inserted at an ideal position, and the inflated portion of the balloon can maintain the proper pressure, thereby preventing the patient from suffering complications due to intubation. It may reduce the inconvenience or foreign body feeling due to the insertion of the tube in the trachea. Further, the balloon-shaped expanding portion may be formed of a soft material, so that inconvenience or foreign matter feeling upon insertion of the intracorporeal tube can be reduced.

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.

The pilot balloon 123 disposed at the end of the expansion tube 120 checks whether the expansion system of the balloon expander 130 is abnormal or not and determines whether a certain amount of air is filled in the balloon expander 130 So that it 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 portion of the balloon-shaped expanding portion in the intracoracal tube of Fig. 1, and Fig. 3 is a sectional view of Fig. 2. Fig. Fig. 4 is a cross-sectional view of the balloon-shaped expanding portion taken along the line X-X 'in Fig. 3;

2 to 4, the intubation tube 100 according to the present invention is provided with indicator units 131, 133, 135, and 137 in a balloon-shaped expanding unit 130. The indicator portions 131, 133, 135, and 137 are used to grasp the shape, position, mounting state, and the like of the balloon expander 130.

The indicator units 131, 133, 135 and 137 include a first indicator unit 131 and a second indicator unit 133 arranged in the longitudinal direction of the balloon expander 130, and a balloon expander 130 And a third indicator 135 and a fourth indicator 137 disposed left and right along the outer circumferential direction of the display unit. The plurality of indicator portions 131, 133, 135, and 137 are formed to prevent the bulb-shaped bulged portion 130 from being disturbed by expansion or contraction.

The first to fourth indicator units 131, 133, 135, and 137 may be made of a metal material or other material recognizable by an external device.

For example, stainless steel, cobalt-chrome alloy, titanium, titanium alloy or nickel-titanium shape memory alloys, The first to fourth indicator portions 131, 133, 135, and 137 may be formed of a harmless metal material.

The first to fourth indicator units 131, 133, 135, and 137 may be formed of a material such as polyvinyl chloride (PVC) or colored silicone. Some of the first to fourth indicator units 131, 133, 135, and 137 may be formed of a metal material, and some of the first to fourth indicator units 131, 133, 135, and 137 may be formed of a colored PVC or a colored silicon.

In addition, the first to fourth indicator units 131, 133, 135, and 137 may include a chip or a sensor that can be used for the purpose of identifying a patient or for other purposes.

The first to fourth indicator units 131, 133, 135, and 137 are photographed or shaped through an X-ray, an ultrasonic wave, a computer tomography or other equipment that can transmit a human body placed outside the patient's body, The degree of inflation of the balloon expanding portion 130, the mounting state of the balloon expanding portion 130, and the position of the balloon expanding portion 130 can be grasped.

If the depth of the intra-tracheal tube 100 is too shallow, the tracheal tendon tends to be easily opened. If the tracheal 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, it has been recognized that an intubation position of the intracorporeal tube 100 is an important problem, and it is generally known that the end of the intracoronary tube 100 is located in the middle of the trachea.

By grasping the positions of the first to fourth integrator units 131, 133, 135, and 137, the position of the balloon expander 130 can be grasped and the in-organ position 100 can be inserted to an ideal position , It can be moved to an ideal position.

By grasping the shapes of the first to fourth integrator units 131, 133, 135, and 137, it is possible to grasp the inflated and inflated state of the inflated inflating unit 130, The air pressure of the expanding portion 130 can be adjusted. The intubation tube 100 may be configured such that the balloon expanding portion 130 can maintain an appropriate pressure because the balloon expanding portion 130 inflated at an excessively high or low pressure may cause complications, So that it is possible to minimize the pain felt by the patient and to prevent a problem from occurring in a body part or the like where the balloon expanding part 130 is contacted.

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 tubular body 110 may be formed from a variety of materials commonly used in medical tubing. The balloon expanding portion 130 can be formed of various soft materials generally used for medical tubes. That is, the inflated bulge 130 may be formed of at least one selected from the group consisting of elastomer, silicone, and soft resin.

By forming the balloon expanding portion 130 using a soft material, it is possible to reduce inconvenience and foreign matter caused by the insertion 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.

5 and 6 are views referred to the description of the endotracheal tube according to another embodiment of the present invention.

Referring to FIG. 5, more than one pair of indicator units 135 and 137 disposed along the outer circumferential surface of the balloon-shaped expanding unit may be disposed. That is, in addition to the indicator units 135a and 137a of the first group, the indicator units 137a and 137b of the second group may be further disposed, or a greater number of indicator units may be disposed. Likewise, the indicator portions 131 and 133 arranged in the longitudinal direction of the balloon expander 130 may be further arranged.

Referring to FIG. 6, the second balloon-shaped expandable portion 140 may be further disposed along with the first balloon-shaped expandable portion 130 disposed in the tubular body 110. At this time, the indicator units 141, 143, and 147 may be disposed in the second balloon expander 140 in the same manner as the first balloon expander 130. .

With this configuration, it is possible to more accurately grasp the position of the intubation tube 100 and the degree of expansion and the like.
