Description

Tracheostomy tube occlusion device with video support function

[0001] The present invention relates to a tracheostomy tube occlusion device inserted into the interior of a tracheostomy tube to close the tracheostomy tube, and more specifically, to a tracheostomy tube occlusion device having a video support function that allows monitoring from the insertion point in the neck to the inside of the trachea during the replacement of the tracheostomy tube.

[0002] A tracheostomy tube is a tube inserted into the trachea of ​​a patient who has undergone a tracheostomy for the purpose of maintaining and securing the airway, treating the respiratory system, and removing sputum or foreign substances from the lungs in cases of airway obstruction or respiratory failure, and is typically used to artificially supply oxygen to patients who are unable to breathe on their own.

[0003] These tracheostomy tubes are inserted into the patient's trachea and are replaced periodically to prevent infection, as they become contaminated with tracheal secretions, saliva, or foreign substances. While the passage to the trachea can usually be verified before replacement, there are cases where the passage is not clearly visible depending on the patient; in particular, there is a problem in that the passage cannot be verified once the tube has entered the cervical insertion site.

[0004] Depending on the physician's skill level, a false lumen may be created and a tracheostomy tube inserted, which can damage surrounding tissues and blood vessels. Additionally, the inability of air to enter the lungs can lead to respiratory distress, and pneumothorax may occur in patients receiving mechanical ventilation. In severe cases, such complications can result in death.

[0005] Therefore, there is a need for the development of technology for a tracheostomy tube occlusion device that allows visualization of the inside of the trachea in order to stably advance the tracheostomy tube into the trachea during replacement, prevent the tube from entering the false lumen, and prevent damage to surrounding tissues and blood vessels, thereby preventing fatal accidents caused by complications.

[0009] (Patent Document 2) JP 4634520, Registration Date: March 31, 2011.

[0010] (Patent Document 3) US 2014-0275772, Publication Date: September 18, 2014.

[0011] (Patent Document 4) US 10561822, Registration Date: 2020. 02. 18.

[0012] An endoscope combined with a monitor can serve as an alternative device for visualizing the inside of the trachea applicable to tracheostomy tube closures. Endoscopes are currently in use in medical settings, and various structures have been developed and utilized depending on their intended use.

[0013] US 11559646 proposes a system and method for video-assisted percutaneous bedside thyroidectomy and tracheostomy. In the proposed system, a fiber stylet is installed to penetrate the inside of a hollow needle, and a camera and a lighting device are installed at the end thereof to transmit and display anatomical images of the patient captured by the camera to a display monitor.

[0014] JP 4634520 proposes an endoscopic tracheal intubation device that prevents internal tracheal damage caused by collision of the insertion part when the endoscope passes into the trachea. In the proposed endoscopic tracheal intubation device, a camera unit and a lighting unit are respectively installed at the end of the insertion part that is inserted into the intubation tube, and an image acquired through the camera unit is output through a monitor unit.

[0015] US 2014-0275772 proposes an intubation device having a downwardly extending stylet inserted into an endotracheal intubation tube. The proposed intubation device is equipped with a camera and a light source installed on the end of the distal tip of the stylet, which penetrates the inside of the protective sheath, and is equipped with a video display that can view an image (endoscope view) captured through the camera.

[0016] US 10561822 proposes a bronchoscope in which one end is connected to a plug-in type screen or an external large screen, and the other end includes a handle that is coupled to a catheter. The proposed bronchoscope is equipped with a recording module and a lighting device inside the end of the catheter.

[0017] However, the prior art described above may have structural problems as follows.

[0018] First, while US 11559646 proposes a technique involving creating an initial tracheostomy opening and inserting a tracheostomy tube, replacing the tube is not easy. Ideally, in clinical practice, tracheostomy tube replacement should be performed safely, simply, and with minimal medical personnel (one person), regardless of the patient's location. However, US 11559646 features a structure where the monitor is connected to a connection hub via a stylet, requiring separate space for the monitor. Furthermore, the configuration of a dilator and stylet is essential, resulting in a disadvantage where the length is longer than that of the tracheostomy tube. Additionally, since the dilator and fiber optic stylet are not designed to be combined, at least two personnel are required for replacement—one to operate the fiber optic stylet and another to insert the tube.

[0019] Second, JP 4634520, US 2014-0275772, and US 10561822 are for oral or nasal intubation, and there is a significant difference in function from the occlusion device proposed in the present invention. The tracheostomy tube must be closed through the occlusion device to induce oral and nasal breathing from tracheal breathing in a tracheostomy patient. However, in the prior art, the structure is not fixed and can move easily (there is a gap) while an endoscope equipped with a camera and a lighting device (light source) is inserted, so the occlusion device cannot perform its inherent role (closing the tracheostomy tube).

[0020] Therefore, the problem (objective) to be solved by the present invention is to provide a tracheostomy tube occlusion device equipped with a video support function that allows the inside of the trachea to be viewed conveniently in real time during the replacement of the tracheostomy tube, thereby enabling the stable insertion of the tracheostomy tube into the trachea and preventing the tube from entering a false lumen, while also preventing damage to surrounding tissues and blood vessels, which can prevent death due to complications.

[0021] In addition, another problem to be solved by the present invention is to provide a tracheostomy tube occlusion device having a video support function that allows the monitor and endoscope to be installed and fixed in the occlusion device, so that the length of the endoscope connected to the monitor is almost the same as the total length of the occlusion device, so that no operation of the endoscope is required (easy to handle as it is automatically aligned at the same time as installation and fixation), so that the tracheostomy tube can be replaced by one person, and also does not require space to place the monitor separately, and can stably close the tracheostomy tube to stably perform its original function.

[0022] Furthermore, the problems to be solved by the present invention are not limited to the problems described above, and various additional problems to be solved may be provided through the technologies described in the embodiments below.

[0023] The present invention, according to an embodiment for achieving the above-mentioned purpose, provides a tracheostomy tube occlusion device having a video support function, which is inserted and installed inside a tracheostomy tube, has a connection port formed at the tip portion through which a monitor, equipped with a mounting port on the rear portion, is coupled and fixed via the mounting port, has a hollow formed in the center through which an endoscope connected to the rear portion of the monitor is inserted and penetrates, has an exposed hole communicating with the hollow, and has an extension portion formed at the end portion through which a camera module and a lighting module installed at the end portion of the endoscope are exposed to the outside through the exposed hole.

[0024] In addition, the above endoscope may be formed such that, when the monitor is fully coupled and fixed to the connection port via the mounting port, the end portion does not protrude further outward than the exposure hole of the extension portion through the exposure hole of the extension portion.

[0025] In addition, an extension connection part in which the mounting hole is installed may be formed on the rear part of the monitor.

[0026] In addition, the extension is formed to have an outer diameter larger than the inner diameter of the hollow formed in the tracheostomy tube, so as to seal the end portion of the tracheostomy tube.

[0027] In addition, the connector may be formed to have an outer diameter larger than the inner diameter of the inlet side of the tracheostomy tube so as to be mounted on the inlet side of the tracheostomy tube.

[0028] As described above, according to the tracheostomy tube occlusion device of the embodiment of the present invention, by providing an endoscope that is inserted and installed inside the tracheostomy tube, has a monitor mounted and fixed at its tip, and has a camera module and a lighting module installed at its end, which extends integrally from the monitor and is exposed to the end of the occlusion device, the inside of the trachea can be stably monitored through the monitor when the tracheostomy tube is replaced, thereby preventing the tracheostomy tube from entering a false lumen and preventing damage to surrounding tissues and blood vessels, thus preventing death due to complications.

[0029] In addition, according to the tracheostomy tube blocking device of the embodiment of the present invention, a monitor is integrally mounted and fixed at the tip of the blocking device, and at the same time, an endoscope is inserted and fixed into the interior of the blocking device, so there is no need to operate the endoscope, allowing the tracheostomy tube to be replaced by one person, and there is no need for additional space to place the monitor, making installation and handling easy.

[0030] In addition, according to the tracheostomy tube occlusion device according to an embodiment of the present invention, the inner diameter of the hollow into which the endoscope is inserted is formed to be approximately the same size as the outer diameter of the endoscope so that no gap occurs between the outer surface of the endoscope and the hollow of the occlusion device, thereby stably installing and fixing the endoscope inside the occlusion device, while stably closing the interior (hollow) of the occlusion device through the endoscope so that the occlusion device can stably perform its original function.

[0031] FIG. 1 is a drawing showing a occlusion device for a tracheostomy tube according to an embodiment of the present invention.

[0032] FIG. 2 is a disassembled view of the tracheostomy tube occlusion device shown in FIG. 1.

[0033] FIG. 3 is a view of the tracheostomy tube closure shown in FIG. 1, seen from below upward.

[0034] FIG. 4 is a cross-sectional view of the assembled state of the tracheostomy tube occlusion device shown in FIG. 1.

[0035] The advantages and features of the present invention and the methods for achieving them will become clear from the embodiments described below in detail in conjunction with the accompanying drawings. Throughout this specification, the same reference numerals refer to the same components. Additionally, where "A and / or B" is written, it may mean both A and B, or either A or B. Furthermore, the size and shape of each component shown in the drawings may be exaggerated for convenience of explanation and are not intended to be limiting.

[0036] FIG. 1 is a schematic diagram showing a tracheostomy tube occlusion device according to an embodiment of the present invention, and FIG. 2 is a disassembled diagram showing the tracheostomy tube occlusion device shown in FIG. 1.

[0037] Referring to FIGS. 1 and 2, the tracheostomy tube block (10) according to an embodiment of the present invention is used to guide the tracheostomy tube (40) to easily enter the trachea.

[0038] As shown in FIG. 2, this tracheostomy tube occlusion port (10) is made of a tubular tube with a hollow (10a) formed so that an endoscope (30), which is integrally connected to the monitor (20), can be inserted through an extension connection part (21) formed on the rear part of the monitor (20).

[0039] FIG. 3 is a view of the tracheostomy tube occlusion device shown in FIG. 1 from below to above, and FIG. 4 is a cross-sectional view of the assembled state of the tracheostomy tube occlusion device shown in FIG. 1.

[0040] Referring to FIGS. 1 to 4, the tracheostomy tube closure (10) according to an embodiment of the present invention has a connection port (11) formed so that a mounting port (22) provided on a monitor (20) is coupled and fixed.

[0041] The mounting member (22) and the connecting member (11) may each be composed of a connector or coupler used to interconnect two tubular bodies. Additionally, they may be connected to each other in a one-touch or two-touch manner so that they can be easily attached and detached. As an example, to connect the mounting member (22) and the connecting member (11) in a male-female manner, a locking projection (22a) may be formed on the outer surface of the mounting member (22), and a connecting groove (11a) into which the locking projection (22a) is connected may be formed on the inner surface of the connecting member (11).

[0042] As shown in FIG. 2, the connecting port (11) may be formed to have a larger inner diameter compared to other parts of the tracheostomy tube closure port (10). Accordingly, the mounting port (22) may be inserted at least partially into the interior of the connecting port (11) and mutually coupled and fixed via the locking projection (22a) and the coupling groove (11a). Of course, the connecting port (11) may also be inserted into the interior of the mounting port (22) and mutually coupled and fixed.

[0043] Meanwhile, the tracheostomy tube block (10) can be fixed to the entrance side of the tracheostomy tube (40) so that it does not get inserted deeper or slide in while inserted into the interior of the tracheostomy tube (40). To this end, a connecting groove may be formed on the entrance side of the tracheostomy tube (40) to which the connecting part (11) of the tracheostomy tube block (10) is fixed in a male-female connection. For example, when the tracheostomy tube block (10) is inserted into the interior of the tracheostomy tube (40) and the tracheostomy tube block (10) is rotated in one direction, the locking projection formed on the outer surface of the connecting part (11) of the tracheostomy tube block (10) is connected in a male-female connection to the locking groove formed on the inner side of the entrance side of the tracheostomy tube (40), thereby maintaining the tracheostomy tube block (10) in a fixed state attached to the tracheostomy tube (40).

[0044] As shown in FIGS. 2 and 3, an extension (12) that protrudes outward from the end of the tracheostomy tube (40) may be formed at the end of the tracheostomy tube (10) according to an embodiment of the present invention when the tracheostomy tube (10) is completely inserted into the tracheostomy tube (40).

[0045] An exposed hole (12a) is formed in the extension part (12) to communicate with the hollow (10a). A camera module (31) and a lighting module (32) provided at the end of the endoscope (30) are exposed through the exposed hole (12a).

[0046] The hollow (10a) may be formed to have an inner diameter equal to the outer diameter of the endoscope (30) so that the endoscope (30) does not move when inserted into the hollow (10a). However, in this case, there may be difficulties when inserting the endoscope (30) into the hollow (10a).

[0047] Accordingly, in the present invention, as an example, the outer diameter of the endoscope (30) can be formed to be approximately 0.1 mm to 1 mm smaller than the inner diameter of the hollow (10a). Through this, when the endoscope (30) is inserted into the hollow (10a), the outer surface of the endoscope (30) is closely attached to the inner surface of the hollow (10a), thereby ensuring airtightness, while allowing the endoscope (30) to be inserted smoothly.

[0048] In addition, as another example of the present invention, the hollow (10a) may be structured such that the inner diameter decreases from the tip to the end of the tracheostomy tube closure (10), and correspondingly, the endoscope (30) may also be structured such that the outer diameter decreases from the tip to the end connected to the monitor (20). This makes it easier to insert the endoscope (30).

[0049] Meanwhile, at least a portion of the extension (12) may be inserted into the tracheostomy tube (40) while the tracheostomy tube closure (10) is fully inserted into the tracheostomy tube (40). At this time, the outer diameter of the portion inserted into the tracheostomy tube (40) may be the same as or slightly larger than the inner diameter of the tracheostomy tube (40). Through this, the extension (12) may seal the end portion of the tracheostomy tube (40) while the tracheostomy tube closure (10) is inserted into the tracheostomy tube (40).

[0050] As shown in Fig. 3, a camera module (31) and a lighting module (32) are installed at the end of the endoscope (30).

[0051] The camera module (31) and the lighting module (32) are exposed to the outside through an exposure hole (12a) formed in the extension (12). The camera module (31) may include a camera for capturing images and a camera lens (optical lens). The images captured by the camera module (31) are transmitted to the monitor (20) via the endoscope (30) and displayed in real time. The lighting module (32) may include an LED lamp.

[0052] As shown in FIGS. 2 and 3, a flange (41) may be installed at the tip of the tracheostomy tube (40). The flange (41) is a member to which a strap or the like is secured to fix the tracheostomy tube (40) to the patient's body, and it is placed over the patient's neck area while the tracheostomy tube (40) is inserted into the trachea. This prevents the tracheostomy tube (10) from being inserted too deeply into the bronchial tube or slipping in while the tracheostomy tube (40) is inserted into the trachea.

[0053] As shown in FIGS. 1 and 3, the endoscope (30) is formed so that its end portion does not protrude through the exposed hole (12a) of the extension portion (12). That is, it can be formed to have a length equal to or smaller than that of the tracheostomy tube occlusion port (10) so that the end portion of the endoscope (30) does not protrude outwardly through the exposed hole (12a) of the extension portion (12) when the monitor (20) is completely coupled and fixed to the connection port (11) via the mounting port (22). For example, the length from the tip of the tracheostomy tube occlusion port (10) to the extension portion (12) can be formed to be equal to or longer than the length of the endoscope (30) so that the end portion of the endoscope (30) does not protrude outwardly through the exposed hole (12a) of the extension portion (12) when the monitor (20) is completely coupled and fixed to the connection port (11) via the mounting port (22).

[0054] Hereinafter, the effects of the occlusion device (10) for a tracheostomy tube according to an embodiment of the present invention will be explained.

[0055] According to an embodiment of the present invention, a tracheostomy tube occlusion device (10) has a monitor (20) mounted and fixed at the tip through a connector (11), and an endoscope (30) is provided inside, which is integrally extended from the monitor (20) and has a camera module (31) and a lighting module (32) installed at the end portion exposed to the end portion of the occlusion device (10). This allows for stable monitoring of the inside of the trachea through the monitor (20) when replacing the tracheostomy tube (40), thereby preventing the tracheostomy tube (40) from entering the false lumen and preventing damage to surrounding tissues and blood vessels, thereby preventing death due to complications.

[0056] In addition, the tracheostomy tube block (10) according to the embodiment of the present invention is installed and fixed by integrally mounting the monitor (20) to the front end of the block (10) through a connection port (11) provided at the front end and a mounting port (22) provided at the rear end of the monitor (20), and the endoscope (20) is inserted and fixed into the interior of the block (10), so that the endoscope (20) does not need to be operated separately, allowing the tracheostomy tube (40) to be replaced by one person. In addition, since no additional space is required to place the monitor (20) separately, there are fewer restrictions on the installation space, and installation and handling are easy.

[0057] In addition, the tracheostomy tube closure (10) according to the embodiment of the present invention forms the inner diameter of the hollow (10a) into which the endoscope (30) is inserted into the tracheostomy tube (10) to be approximately the same size as the outer diameter of the endoscope (a difference of about 0.1 mm to 1 mm) so that no gap is created between the outer surface of the endoscope (30) and the hollow (10a) of the tracheostomy tube (10), thereby stably installing and fixing the endoscope (30) inside the tracheostomy tube (10), while stably closing the interior (hollow) of the tracheostomy tube (10) through the endoscope (30) so that the tracheostomy tube (10) can stably perform its original function.

[0058] As described above, preferred embodiments of the present invention have been explained and illustrated using specific terms; however, such terms are used solely to clarify the invention. Furthermore, it is obvious that various modifications and changes may be made to the embodiments and described terms of the present invention without departing from the technical spirit and scope of the following claims. Such modified embodiments should not be understood separately from the spirit and scope of the present invention, but should be considered to fall within the scope of the claims of the present invention.
