Description

X-shaped bronchial suction catheter

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction catheter for removing sputum, and more particularly, to an economical and easy-to-use sputum removal suction catheter for a patient requiring an artificial sputum discharge.

Secretions from healthy human lungs or bronchi (commonly referred to as 'sputum') can be removed through mucociliary ciliary movement and cough reflexes. However, in respiratory-related patients, the secretions become too large or too viscous to be discharged in a normal manner, and secretions become lodged in the lungs or bronchi. These secretions filled with lungs or airways are dangerous because they can interfere with the patient's breathing and cause bacterial infections.

A method of discharging sputum is known as a position therapy such as inverting the upper body so that sputum can flow out by gravity, a vibration therapy for allowing the sputum to be discharged through vibration using a massage machine or a vibrator, etc. have. However, this method is possible when the patient's condition is relatively good.

Patients with tracheostomy or tracheal intubation, patients with pneumonia, acute respiratory failure, sequelae of pneumonia, patients with mucus impaction, neurological problems with difficulty in sputum production, neurosurgery, rehabilitation medicine, etc. . In the case of patients who are unable or unable to cope with a large amount or high viscosity sputum by incontinence therapy or vibration therapy, it is necessary to continuously or periodically discharge artificial sputum by forced suction.

Suction therapy can be performed by suction catheter or bronchoscopy. The former is for relatively easy removal of secretions from the trachea or bronchus, and the latter is a procedure performed by a skilled worker when there is secretion to the lower lobe of the lung.

The conventional suction catheter has one or more suction holes formed at its upper end and a thin tube made of a material having appropriate flexibility and equipped with a sound pressure control part and a connection part at the other side as shown in the conceptual diagram and actual example attached to FIG. . The connecting portion is coupled to the suction unit via a predetermined pipe. In use, the negative pressure control part is closed or opened to form a negative pressure in the tube, and the secretion is discharged to the suction bottle at the front end of the suction device through the suction hole. In practice, a suction catheter is inserted through the nose or mouth, or in the case of airway incision patients, through a tube (see FIG. 1B). However, in the conventional suction catheter, since the length of the tube is short in consideration of the removal of the secretion in the trachea, it is difficult to reach the lower side of the bilateral lungs where the secretions are accumulated. Even if a suction catheter with a long tube length is inserted in a blind state, it is very difficult to insert the suction catheter into a lung of a desired direction. Because the diameter of the right airway (bronchus) is larger and closer to vertical, it is known that the inserted suction catheter is mostly advanced to the right lung. Therefore, it is very difficult to remove secretions from the left lung.

Therefore, it is common to use a bronchoscopy with suction function to remove the secretions in the lower lung of the left lung. However, because bronchoscopy requires specialist personnel such as respiratory therapists, nurses, and bronchoscopy equipment, it is time and costly. In the case of the intensive care unit, complications such as decreased oxygen saturation during the procedure or moving to the laboratory are also possible. Therefore, it is often difficult to treat patients even if they are necessary.

PCT / US2014 / 029265 (Korean Patent Laid-open Publication No. 10-2015-0140295) discloses a catheter having two bifurcated catheters inserted into one intubation-envelope, inserting an intubation tube into the trachea, A suction catheter device that can be inserted into the bronchus (see Fig. 2a). 2B, the end of each catheter is bent, the end of the catheter has a half-moon cross-section, and the end of the endotracheal intubation has a joint corresponding to the cross-section of each catheter, . When the endotracheal intubation of the device is inserted into the patient's organs, the end of each catheter (shown in red) is positioned towards the left and right bronchi as shown in Figure 2c. However, since the ends of the respective catheters are hardly arranged in the direction of the left and right bronchi as shown in FIG. 2c, the joint connected to the ventilation adapter is controlled to control the direction.

Such a catheter device is required to have a special structure (a half-moon-shaped flexible tube with a cross section, a joint-joint fitting with two half-moon openings, a structure for rotating a joint fitting, etc.) So it is not convenient to use.

In addition, the endotracheal tube has a built-in catheter, the catheter has a half-moon cross-section, and the joint is prevented from twisting or bending, so that the distal end of the catheter is substantially rigid. There is also a risk.

On the other hand, the anatomical distribution of the tracheal segment in the respiratory tract is divided into the right branch and the left branch of the organ. The right main bronchus is divided into the right upper bronchus and the right middle bronchus intermedius. The right middle bronchus is divided into the right middle lobe bronchus and the right lower lobe bronchus. On the other hand, the left main bronchus is divided into left upper lobe bronchus and left lower lobe bronchus. The organs are about 11 ~ 13 ㎝ in length and 1.5 ~ 2.5 ㎝ in diameter. The right main bronchus is inclined about 20 ~ 25 degrees with respect to vertical, and the length from the branch of bronchus to the lower bronchus of right lower lobe is about 7 ~ 10 ㎝. The left main bronchus is about 40 ~ 50 degrees from the vertical and the length from the branch of the trachea to the lower bronchus of the left lower lobe is about 8 ~ 10 ㎝. (see http://www.bronchotraining.org/spip.php?article11)

However, up to now, there is no known suction catheter considering the anatomical characteristics of the trachea of both lungs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the accompanying drawings. It should be understood, however, that the appended drawings illustrate only the contents and scope of technology of the present invention, and the technical scope of the present invention is not limited thereto. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the technical idea of the present invention based on these examples. Also, when reference numerals are used in the drawings, the drawings are used only for illustration purposes and are not intended to limit the elements.

In the present invention, the lower end, the lower end, the lower end, and the like refer to the side or portion to be inserted into the bronchial tube at the time of use, and the upper end, upper end, upper end,

As described above, according to the present invention, there is provided a suction catheter comprising: a suction catheter having a connection portion connected to a suction device at an upper end thereof and a sound pressure control portion; and two suction catheters having one or more suction holes formed at a lower end thereof, The present invention relates to a suction catheter for simultaneous aspiration of both lungs, wherein the distal ends of two separated lower tubes of the suction catheter when there is no external force (hereinafter referred to as "separation tube" for convenience of explanation) are spaced apart. Briefly, the suction catheter according to the present invention can be seen to be a combination of the middle portions of two suction catheters having a longer tube length than those conventionally used. Through such a simple coupling, which has not been considered in the past, it can be used in a totally different manner from the conventional suction catheter, and a completely different effect can be obtained.

An example of a suction catheter according to the present invention is shown in Fig.

As shown in the drawing, the suction catheter according to the present invention is characterized in that a middle portion of two suction catheters, in which a normal connection portion and a negative pressure control portion are mounted on an upper end thereof and one or a plurality of suction holes are formed on a lower end thereof, (Coupling portion) and has a topology and a bottom (separation tube) separated from each other and has a topology of substantially X-shaped structure.

The material of the suction catheter tube portion is a plastic material such as non-toxic medical grade PVC, silicone, latex, PE, teflon or the like which is a material of a normal suction catheter tube. The outer diameter of the tube may also be determined in the usual range of 5 to 24 gauge (4.6 to 0.5 mm), but theoretically it should be less than 1/2 of the diameter of the trachea and less than the diameter of the lower bronchus. However, the bottom of the suction catheter must reach the trachea to the lower bronchus in use. Since the length from the bronchus to the lower lobe is about 7 to 10 cm on the right side and about 8 to 10 cm on the left side, the suction catheter according to the present invention It is sufficient that the length of the separation pipe below the coupling portion is about 10 cm. If no external pressure or restriction is applied to the suction catheter according to the present invention, it is preferable that the two separating pipes have a 'splashing elasticity' that elastically flares slightly (at intervals of several millimeters). It will be appreciated by those skilled in the art that the ends of the side-by-side plastic tubing can be slightly widened by employing suitable means and means.

Naturally, when the suction catheter according to the present invention is applied to a patient, the X-plane structure formed by the two side-by-side suction catheter tubes is inserted so as to coincide with the inverse Y- . However, when the suction catheter enters the oral cavity, the nasal cavity, or the tube, it becomes blind, and it is not known how the X-plane of the suction catheter is oriented. However, according to the present invention, since the parallel direction of the exposed upper tube is the same as the parallel direction of the inserted tube to be inserted, the practitioner must adjust the direction of the plane formed by the two tubes of the exposed portion to be the plane formed by the patient's bronchus For convenience, it can be simply controlled).

Thus, the practitioner rotates the entire suction catheter according to the present invention with reference to the exposed portion at the time of the procedure, thereby aligning the orientations. Therefore, it is preferable that the tube used in the suction catheter according to the present invention has a certain degree of resistance to twisting. The degree of resistance to distortion is sufficient so that the ends of the two separate tubes will not naturally spread when the two bronchial tubes are inserted respectively.

The suction catheter according to the present invention is characterized in that at least one of the two ends of the separation tube is bent away from the center so that the distal end of the separation tube can be well separated and introduced into the left and right bronchi 3a). In particular, in the case where only one end is bent, it is preferable that the one to be inserted into the left bronchus is bent. However, if the distal end of the separator is bent outward, it may damage the trachea during insertion. Therefore, it is desirable that the distal end portion of the separation tube is designed so as to slightly bend inward again.

FIG. 3B is a conceptual diagram of a process of inserting a suction catheter according to the present invention into a lung. For the sake of convenience, the ~ bronchus ~ (under the middle) and the soreness catheter were expressed, and the upper part of the suction catheter was omitted. Various preparatory procedures and precautions to be performed at the time of aspiration of the sputum are the same as those in the conventional art, so that the description thereof is omitted.

First, in patients with oral or nasal cavity or airway incision, insert the two ends of the separation tube all at once through the tube and gradually push it while adjusting the orientation. When the end of the separation tube passes through the organ (A in the figure) and reaches the branch of the organ - the two ends of the separation tube are slightly open due to the widening elasticity - the ends of the separation tube enter the right bronchus and the left bronchus respectively B in the drawing), and then to the right and left lower left bib branches (C in the drawing). Then, sputum aspiration is performed according to a conventional method. The subsequent process is the same as usual.

On the other hand, as described above, the length from the branch of the trachea to the tracheal bronchus is about 7 ~ 10 ㎝ on the right side and about 8 ~ 10 ㎝ on the left side. Therefore, when using the suction catheter according to the present invention, the length of the isolation tube may be set to a length difference of about 1 to 2 cm (not shown) so as to correspond to the length of the isolation tube. For example, the length from the tracheal branch to the left and right lower lobe of the trachea varies from patient to patient. In this case, the patient's thoracic tomography photograph is used to estimate the length and the angle of branching if necessary (see FIG. 4) A suction catheter can be provided. For example, a basic suction catheter having a sufficiently long separation tube is provided, and the ends of the separation tube (for example, 8 and 10 cm in the case of the patient shown in Fig. 4) are cut to meet the anatomical characteristics of the patient And the sucking hole is pierced, so that a patient-customized suction catheter can be made.

If the length of the dissection tube is different, add information about the direction in which the dissection tube length is different to the exposed part of the suction catheter. For example, when the color of a longer pipe is changed or an arrow or the like is displayed, the orientation control can be performed so that the long separation pipe can be inserted to the left.

As described above, according to the present invention, the orientation can be controlled by various methods. However, the suction catheter according to the present invention may have an additional structure capable of making the orientation more clear. For example, a guide pipe slidably installed near the distal end of the separation tube may be further included (not shown). According to this, the operator inserts the suction tip of the two separation tubes into the airway at the same time with the tip of the suction tube being built in the guide tube. When reaching the branch of the engine, the guide tube is stopped and the catheter is pushed in. Then, the two separators are exposed outside the guide tube and naturally inserted into the left and right bronchi as they open. Since the guide tube houses the two separation tubes side by side, it is in a flat shape, and the orientation control becomes very easy.

In accordance with the present invention as described above, it is possible to provide a patient with airway incision or airway intubation, patients suffering from pneumonia, acute respiratory failure, sequelae of pneumonia, mucus impaction, patients who need sustained release of sputum, It is possible to remove secretions of both lungs at the same time by convenient and safe application to medical patients.
