Description

Endo tube and system with internal treatment function {ENDO TUBE AND SYSTEM CAPABLE OF TRACHEA TREATMENT}

The present invention relates to an endo tube inserted into the inside of an organ, and more particularly, to an endo tube to which a function is added to perform a predetermined treatment on the inside of the organ. In addition, the present invention relates to a treatment system inside an organ using an endo tube.

The passage of air entering the lungs of the human body passes through the nose, mouth, pharynx, and larynx, and is divided into trachea, bronchi, bronchioles, capillary bronchi, and alveoli. The respiratory system is divided into upper airways such as the nose, pharynx, and larynx, lower airways such as trachea, bronchi, bronchioles, and capillary bronchi, and lung tissue such as alveoli, alveolar duct, and alveolar sac.

Endo tube is an integrated term that refers to a device including a ventilation tube that is inserted through the patient's airways to the bronchi, and is applied to emergency patients who have difficulty breathing on their own due to loss of consciousness or a part of the path from the larynx to the trachea is blocked. It is used to supply air to the lungs.

Meanwhile, an expandable balloon may be disposed outside a portion of the endo tube inserted into the organ. By inserting the end of the endo tube into the trachea and then injecting air or liquid into the balloon and expanding it, the airtightness between the outer wall of the endo tube and the inner wall of the trachea is maintained, and the end of the endo tube inserted to a specific position is specified. It can be prevented from exiting or going deeper in the position.

Referring to FIG. 1, various endo tubes according to the prior art are shown and described in the form of an improved form of such a general endo tube.

First, referring to Patent No. 10-0868781 (name: airway intubation system), an improved endo tube will be described (hereinafter, referred to as'Prior Art 1').

In the prior art 1, a rear open end having an adapter to which an oxygen supply device is connected, a flexible tube extending from the rear open end and inserted into the patient's airway, is formed at one end of the flexible tube, and is formed on the airway side when the airway is inserted. The front open end, which is formed on one side of the flexible tube and expands by air supplied through the air line, is arranged at a predetermined position on the flexible tube and a flow valve that allows air flow only to the air line side. There is provided an airway intubation apparatus comprising a light emitting part connected to an electric wire extending along the line toward the flow valve.

In (a) of FIG. 1, when the airway intubation system of the prior art 1 is inserted into the patient's airway, the light output by the light emission of the light emitting unit 30 penetrates the skin of the patient's neck so that the doctor can check it. Shows. According to the prior art 1, there is an advantage of being able to accurately and quickly determine whether or not airway intubation.

In addition, as another form of improvement of the endo tube, there may be mentioned Patent No. 10-1413914 (name: tracheal intubation apparatus using an infrared sensor) (hereinafter referred to as'prior art 2').

In the prior art 2, a tracheal intubation apparatus using an infrared sensor capable of inserting a stylet into a precise position within a body organ is disclosed, which is a flexible hollow tube inserted into the trachea, a style inserted into the tube. Let; An infrared sensor provided at one end of the stylet, and a sensing unit connected to the other end of the stylet to sense a predetermined specific distance through the infrared sensor.

In (b) of FIG. 1, an infrared sensor 230 and a light receiving sensor 234 disposed at an end of the tube 210 are shown. Accordingly, since the distance from the distal end of the tube 210 to a specific location can be determined, the tube can be accurately inserted in a specific location in the organ without checking through a stethoscope or the like.

The endo tubes discussed above pursue the purpose of inserting the endo tube to the correct position, and sufficiently achieve such purpose. However, the endo tube according to the prior art can only provide its own basic function, that is, supply oxygen or air into the patient's lungs, and perform other treatments on the patient's organs or lungs. It is impossible to do, nor is it not being considered.

Respiratory infections are caused by bacterial or viral infections. Among them, well-known representative viruses are influenza virus and corona virus. In addition, the location at which the symptoms of respiratory infections are expressed varies depending on the type of bacteria or virus. That is, symptoms of infection may appear in some or complex locations of the upper airway, lower airway, and lung tissue. Influenza virus is known to develop symptoms mainly in the upper airways, and viruses such as Corona-19 are known to develop symptoms mainly in the lower airways and lung tissue.

For patients with such respiratory infections, an existing endo tube can be used.Since the existing endo tube can only provide the function of supplying oxygen or air, the patient can overcome the respiratory infection only by his own immunity. There is.

Therefore, the idea of adding a function that can help overcome respiratory infections to the existing endo tube has emerged.

The present invention intends to additionally provide a useful function other than the oxygen supply function by using an endo tube inserted into an organ to supply oxygen to a patient. That is, the present invention is an internal organ treatment capable of performing a treatment that directly kills antigens present in the interior of the organ or the interior of the lung and/or regenerates or activates the internal tissue cells of the organ or the lung.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of an endo tube and system having an internal treatment function according to the present invention will be described. For reference, since terms referring to each component of the present invention are exemplarily named in consideration of their functions, the technical content of the present invention should not be predicted and limited by the term itself.

First, referring to FIG. 2, a structure and operation method of an endo tube having an internal organ treatment function according to an embodiment of the present invention will be described. Referring to the drawings, the endo tube 100 having an internal organ treatment function according to an embodiment of the present invention is inserted into a patient's organ to directly supply oxygen or air to the patient's organ or lung. , A light-emitting element 210 that emits special light for performing a predetermined treatment on the inside of an organ or lung, based on the structure and shape of a conventional general endo tube, and a controller for operating the light-emitting element It can be understood that 300 has been added. That is, the endo tube 100 having an internal organ treatment function according to the present invention may include a ventilation tube 110, a light emitting element 210, and a controller 300.

Ventilation tube 110, as a main component of the endo tube, is a member in the form of a long tube that can be set one side and the other side. Here, the side inserted from the ventilation tube 110 into the patient's organ is defined as'one side', and the opposite side may be connected to the oxygen supply device 400 and may be defined as'the other side'.

Here, at one end of the ventilation tube 110, one or more murphy eyes may be formed in addition to the end opening of the tube itself and/or the sidewall of the tube. A connector 122 designed to connect the tube to the oxygen supply device 400 or the arm bag may be installed at the other end of the ventilation tube 110.

In addition, a balloon 134 may be disposed on the outside of one side of the ventilation tube 110, and a connection pipe 132 communicating with the balloon 134 is ventilated (for example, through the inside of the ventilation tube wall). The other side of the tube 110 is formed to be exposed to the outside, and a pump 130 capable of injecting or discharging any fluid into the balloon may be connected to the exposed portion of the connector 132. The pump 130 may include a valve capable of controlling the flow of fluid. Using the pump 130, air or water may be injected into the balloon 134 to inflate the balloon, or the air or water injected into the balloon may be discharged to contract the balloon.

The light-emitting element 210 may be disposed at an arbitrary position at least at a portion of the ventilation tube 110 inserted into the patient's organ. In an embodiment of the present invention, the light-emitting element 210 is a first light-emitting element 210 disposed at an end of one side of the ventilation tube 110 and/or a second light-emitting element disposed on a sidewall of the ventilation tube 110 It may include 220.

Ventilation tube 110 of the endo tube according to the present invention, the end of one side may be inserted into at least the keel of the organ.

In addition, the first light-emitting element 210 is preferably disposed to face each bronchi branched to the left and right of the keel, and may include at least two light-emitting elements. Further, each of the light-emitting elements constituting the first light-emitting element 210 may be set in a direction so that light can reach deep inside each bronchi on the left and right sides of the keel. Each of these light-emitting elements may be implemented so that the facing direction can be arbitrarily adjusted from the outside, but in order to reduce the size and simplify the device, it is preferable to be fixed and installed in an optimal direction. For example, each light emitting element can make 45° with respect to the longitudinal axis of the ventilation tube. The light-emitting element may be, for example, an LED. Since the LED has a spreading angle (ie, radiation angle) of about 120°, the angle at which each light-emitting element is directed is completely in the direction of the bronchi of each patient. There is no need to match. Therefore, as described above, even if it is placed in an inclined angle of only 45°, it will be able to sufficiently respond to various directions of the bronchi of various patients.

Naturally, the first light-emitting element 210 and the conductive wire 212 leading to the first light-emitting element should be properly sealed so as not to be exposed to moisture in the patient's body.

The second light-emitting element 220 is for irradiating light to the inner side wall of the patient's organ, and may be disposed on the inner surface of the side wall of the ventilation tube 110 or on the outer surface (even, the second light emission The element 220 may be disposed within the side wall of the ventilation tube 110). In addition, the second light-emitting element 220 is a part inserted into the body of the ventilation tube 110 to irradiate light to a specific part inside the organ (that is, as a part inserted into the patient's organ, reaching the keel in the organ). It may be disposed only in a part of (indicating from the end of one side of the ventilation tube to the part to be located in the oral cavity of the patient), but preferably, the whole of the inserted part to irradiate light evenly to all parts inside the organ Can be placed on To this end, the second light-emitting element 220 may include two or more light-emitting elements distributed in various ways in the ventilation tube 110. For example, a plurality of flexible substrates in which a plurality of light emitting elements are arranged in a row are arranged along the longitudinal direction of the ventilation tube 110, and two or more flexible substrates are arranged at regular intervals along the circumference of the ventilation tube 110. Can be placed. Here, too, since the radiation angle of the LED may be about 120°, it is possible to sufficiently irradiate most of the inside of the engine by arranging 2 to 4 flexible substrates around the ventilation tube 110.

On the other hand, the second light-emitting element 220 and the conducting wire 212 should also be properly sealed so as not to be exposed to moisture in the patient's body. For example, the second light-emitting element 220 is outside the ventilation tube 110. When disposed on the side surface, a covering tube 115 surrounding the second light emitting element 220 from the outside is provided, and open portions of both sides of the covering tube 115 are placed on the outer surface of the ventilation tube 110. Sealing may be achieved by bonding.

Treatment that can be achieved through the light emitting device 210 in the present invention is, for example, a treatment for killing or disinfecting specific antigens (ie, bacteria, viruses, etc.) present inside the patient's organs and/or It may include a treatment to regenerate or activate the tissue cells constituting the organ.

Accordingly, the light emitting device 210 may be selected from emitting light having a wavelength capable of performing at least one of the treatments described above.

In general, UV-C with a wavelength near 254 nm has the effect of sterilizing bacteria and viruses. Therefore, irradiating light of this wavelength to the organs and lungs is effective in treating respiratory infections. On the other hand, light with a wavelength of near 405 nm is effective in removing bacteria and viruses that are deeper than the surface of organs or lung tissues because the transmittance in the body is high, although sterilizing power is lower than that of UV-C. Accordingly, the light emitting device of the present invention can be selected from those emitting wavelengths having such sterilization and disinfection effects. The wavelength range can be selected from 200 to 500 nm.

In addition, in general, it is known that light having a wavelength of 600 to 1000 nm is effective for regeneration and activation of tissue cells. Therefore, by irradiating light of this wavelength to the tissues in the organs with respiratory infections, treatment efficiency can be improved. Accordingly, the light-emitting device of the present invention can be selected from those that emit a wavelength having such a cell regeneration effect. That is, the wavelength range may be selected from 600 to 1000 nm.

The controller 300 is preferably disposed outside the endo tube 100, particularly outside the patient, supplies power to the light emitting element 210 of the endo tube 100, and turns on/off the light emitting element 210 Control off. In particular, the first light-emitting element 210 and the second light-emitting element 220 are individually controlled, and at least two light-emitting elements constituting the first light-emitting element 210 or the second light-emitting element 220 are individually controlled. Thus, it is designed to variously control the emission intensity and emission pattern of light irradiated toward the interior of the patient's organ.

On the other hand, in another embodiment, the controller 300 may be incorporated into the endo tube 100 (including the battery).

The controller 300 disposed outside the patient is connected to the light-emitting element 210 through a wired wire 212, and supplies and controls a voltage or current through the wire 212 to control the light emission intensity and pattern. do. For example, when driving the light-emitting element 210 to provide a sterilization and disinfection effect, to minimize damage to the cells of the organ or lung tissue by the irradiated light, luminous intensity, luminous pattern, light emission Control the time, etc. The control method of the light emission operation includes, for example, continuously turning on or off light, turning on or off light emission in a variable period, intermittently or continuously changing the intensity of light emission in the on period, and emitting light. And changing the wavelength of light.

The conductor 212 connecting the controller 300 and the light emitting element 210 may be preferably disposed inside the wall of the ventilation tube 110 (see FIG. 3).

Referring to FIG. 3, it can be seen that a very thin conductor 212 can extend through the inside of the wall of the ventilation tube 110. In addition, although not shown, it can be understood that the connecting pipe 132 for expanding or contracting the balloon 134 may also extend through the wall of the ventilation tube 110 in a manner similar to the conductor of FIG. 3. will be.

In another way, a method of printing the conductive wire 212 on the outer or inner wall of the ventilation tube 110 may be considered. In addition, when the covering tube 115 is provided, it may be considered to arrange the conducting wire 212 in the space within the covering tube 115.

4 is a diagram schematically showing the configuration of an internal treatment system using an endo tube according to the present invention. The internal treatment system has an endo tube 100 connected to the oxygen supply device 400, a light emitting element 210, and a controller 300 as a basic configuration. Additionally, in the present invention, a temperature sensor 230 may be further included.

For the endo tube 100 and the light emitting device 210, the above description may be referred to.

On the other hand, the controller 300 includes a power supply unit 310 for operating the light-emitting element 210, and also includes a light-emitting element driving unit 320 for operating the light-emitting element 210 with a predetermined intensity and light emission pattern. do.

The temperature sensor 230 may be disposed at, for example, a portion of the endo tube 100 that is closest to or in contact with the surface of the organ at the portion inserted into the body. In particular, the temperature sensor 230 is preferably disposed to measure the temperature of the tissue of the organ to which light is irradiated by the light emitting element 210. Thus, the temperature sensor 230 measures the temperature of the tissue on which a specific treatment is being performed by the light emitting element 210, and the controller 300 checks the measured temperature to control the operation of the light emitting element 210 can do.

When the temperature sensor 230 is used, it is possible to prevent cells of a tissue irradiated with light from the light emitting device from being damaged by high heat.

Further, the temperature sensor may be a temperature switch 230 designed to turn the circuit on or off at a specific temperature. The temperature switch 230 may be, for example, a bimetal or bellows type switch. The temperature switch 230 may be connected in series with the light emitting element 210. That is, the power supplied to the light emitting element 210 is configured to pass through the temperature switch 230. Thereby, by the operation of the temperature switch 230, since the wire connected from the controller 300 to the light emitting element 210 can be turned on or off, the light emitting operation of the light emitting element 210 can be directly and immediately controlled. You will be able to.

Such a temperature switch 230 is disposed in the vicinity of the light-emitting element 210 or outside the ventilation tube 110, so that the light-emitting element is converted to the light-emitting element in response to overheating of the light-emitting element or overheating of the tissue inside the organ irradiated with light from the light-emitting element. It can immediately cut off the supplied power.

In this way, if the temperature switch 230 for physically turning on or off the circuit is used, even if an operation error of the temperature sensor or a control function error of the controller occurs, overheating inside the light emitting element or the engine can still be effectively blocked.

In addition, those of ordinary skill in the technical field to which the present invention pertains will be able to make various modifications and variations without departing from the essential characteristics of the present invention, and all technical ideas within the scope equivalent to the present invention are the present invention. It should be interpreted as being included in the scope of rights of
