Description

Endotracheal tube with depth measurement {ENDOTRACHEAL TUBE FOR DEPTH MEASUREMENT}

The present invention relates to an endotracheal intubation tube, and more particularly, to an endotracheal intubation tube that enables measurement of intubation depth during intubation.

Endotracheal intubation is a procedure in which a tube is inserted into the trachea to secure the airway in patients requiring airway maintenance or respiratory therapy. By endotracheal intubation, the airway can be maintained, and ventilation and oxygenation can be efficiently performed, so that effective aspiration and emergency medicine can be administered through the airway.

For example, the procedure involves general anesthesia, emergency cardiac arrest, respiratory failure, severe upper airway obstruction, head and neck injury, severe facial burns, and intratracheal aspiration of gastric contents.

After intubation of the endotracheal tube, the position of the tube may change according to the movement of the head and neck, which may cause serious side effects. This side effect is that the tube can go deep into the trachea and only one lung is ventilated. On the contrary, the tube can be pushed toward the mouth, resulting in a distal tube or damage to the vocal cords. In particular, patients undergoing head and neck surgery change the position of the tube to varying degrees according to head and neck movements (such as bending, straightening and turning sideways).

After endotracheal tube intubation, when the central vein is held or the head is turned or turned sideways for surgery or the like, the cuff of the tube moves upward, irritating or damaging the vocal cords, and in severe cases, tube dissection occurs. Damaged vocal cords cause a variety of side effects, from vocal abnormalities to upper respiratory tract obstructions, so attention is required.

On the contrary, when the endotracheal tube is pushed in the bronchial direction, the pressure in the ventilating lungs increases due to one-pulmonary ventilation, which increases the risk of alveolar damage, pneumothorax, and tonic pneumothorax. need.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

1 is a cross-sectional view of the endotracheal intubation tube capable of measuring depth according to an embodiment of the present invention.

Referring to FIG. 1, the endotracheal intubation tube 100 capable of measuring depth according to an embodiment of the present invention is disposed outside the lower end of the tube body 110 and the tube body 110 that is inserted into the trachea of the patient. And an expandable cuff 120 for pressing the tracheal wall or esophageal wall and a coil 130 disposed inside the tube body 110 provided for the depth of the intubation or the positioning of the inserted tube.

Cuff 120 disposed on the outside of the lower end of the tube body 110 is inflated as a role for preventing air leakage and gastric fluid from being aspirated from the lungs after the endotracheal tube is inserted, pressure is applied to the tracheal wall This is possible.

The coil 130, when measuring the depth of intubation or the position of the tube using the ultrasonic wave, it is possible to check the depth of the intubation or tube by acting as a reflector.

In the form of winding the coil 120 inside the tube body 110 of the present invention, when the coil 120 is wound in parallel, when the tube body 110 is thin when the endotracheal tube is inserted in the process of insertion The coil 120 may be broken.

Therefore, in the form of winding the coil 120 inside the tube body 110, the coil 120 can be wound in a spiral shape, so that the tube body 110 is not broken even when the tube body 110 is thin. It is effective.

In one embodiment, the coil 130 is disposed at an upper end of the cuff 120. Since the length of the cuff 120 and the distance from the upper end to the distal end of the cuff 120 are determined or known in advance, the distal end of the endotracheal intubation tube body 110 is inserted by measuring the position of the upper end of the cuff 120. Accurate confirmation of the location is possible.

The coil 130 is disposed at the upper end of the cuff 120, not at the lower end of the cuff 120 or the distal end of the tube body 110. However, unlike the present invention, when the coil 130 is located at the lower end of the cuff 120 or the distal end of the tube body 110, the position of the coil 130 is measured by ultrasonic waves. When the lower end of the cuff 120 or the distal end of the tube body 110 is intubated in the trachea, ultrasonic waves cannot be reflected by the bone of the patient and thus the coil 130 may not be identified.

Accordingly, the position measurement is possible only when the coil 110 is disposed at the upper end of the cuff 120.

As described above, according to an embodiment of the present invention, by placing the coil 130 inside the tube body 110 and the upper end of the cuff 120, precisely measuring the depth of the intubation or the position of the tube when viewed with ultrasound It has the effect of making it possible.

In the present invention, the coil 130 serves as a reflector of the ultrasonic wave, to measure the position of the coil 130 using the reflection of the ultrasonic wave on the coil 130, through which the depth of the endotracheal tube Since the measurement or positioning of the tube, the better the reflection of the ultrasonic waves, it is possible to accurately determine the endotracheal tube.

Therefore, the coil 130 may be formed of a metal to make the reflection of the ultrasonic wave well when measuring the position of the coil 130 in one embodiment.

In addition, the coil 130 may be provided with one or more grooves so that the reflection of the ultrasonic waves is performed in one embodiment.

Positioning of the endotracheal intubation tube is not only used for accurate intubation during tube intubation, but can also identify the position of the tube when there is movement of the tube, such as the patient moving the neck or head during surgery after the endotracheal tube intubation. In particular, it is useful for patients with congenital malformations such as children and head and neck.

However, as described above, in the case where there is a positional movement of the tube after the tube is inserted into the trachea, when the tube enters a deep part of the trachea and only one lung is ventilated, the pressure of the ventilating lung increases, resulting in alveolar damage or pneumothorax. In addition, the risk of developing tension pneumothorax increases and alveolar contraction may occur in non-ventilated lungs. On the contrary, if the tube is pushed out to the mouth, it may be a detubation or a vocal cord injury.

In order to prevent such side effects, the position of the intubation tube should be continuously checked during surgery.

Ultrasonic waves may be used as described above to check the position of the tube, but since the ultrasonic measuring apparatus is bulky and heavy, it is difficult to continuously measure the position using the ultrasonic apparatus during surgery.

In order to solve the above problem, magnetism may be used to confirm the intubation depth of the intubation tube or the position of the tube during surgery.

In another embodiment, the coil 130 is a metal on which magnetic acts, and may be configured to adjust the position of the magnetic body in the position detector disposed outside the body of the patient. In addition, the coil 130 is another embodiment, as a magnetic material, may be to adjust the position of the magnetic metal in the position sensor disposed outside the body of the patient.

That is, the coil 130 may be a metal on which magnetic acts, or may be a magnetic body.

The endotracheal intubation tube 100 includes an intubation tube body 110, a cuff 120 and a coil 130.

The cuff 120 is disposed outside the lower end of the tube body 110. The cuff 120 intubates the endotracheal tube and acts to prevent pressure from being applied to the tracheal wall to prevent air leakage and gastric fluid from being sucked into the lung.

The coil 130 is made of metal to serve as a reflector when measuring the depth of intubation or the position of the tube by using an ultrasonic device. This allows for intubation depth or tube positioning. Detailed description of the coil structure and the arrangement position described above will be omitted.

In addition, the coil 130, as will be described later, by interacting with the position identifier 210 in the positioner 200 by the magnetic field to enable the positioning position of the intubation tube through the positioner 200.

The coil 130 may be a magnetic material, and the position identifier 210 may include a metal having a magnetic function of which the position is controlled by the magnetism of the coil.

In addition, the locator 200 may be disposed outside the neck into which the tube of the patient is inserted by various methods. In one embodiment, the locator 201 may be physically connected to the intubation tube. For example, the locator 201 may be disposed in the neck region of the patient in a state where the locator 201 is physically coupled to the endotracheal intubation tube region disposed outside the mouth of the patient.

In another embodiment, the position measuring device 202 may be manufactured as a separate module physically spaced from the intubation tube. For example, the locator 202 may be in the form of a band or sticker attached to the outside of the patient's skin. That is, the position measuring device 202 may be attached to the outside of the patient's skin corresponding to the position where the coil 130 disposed inside the tube body 110 should be located.

Hereinafter, a method of guiding a position change of the coil 130 in the endotracheal intubation tube to the medical staff through the position identifier 210 of the position detector 200 will be described in detail.

Referring to FIG. 3, in another embodiment of the present invention, the endotracheal intubation tube device capable of measuring depth is a position measurer 201 in which a position detector 201 is physically coupled to an endotracheal intubation tube region.
