The present invention relates to a 119 emergency rescue video laryngoscope system and an emergency rescue method using the same.Even in a situation where intubation of the laryngoscope is urgently necessary for an emergency patient, such as inhaling toxic gas, a first-class emergency medical technician (a second-class emergency medical technician Laryngoscope tracheal intubation is illegal even if there is a doctor's instruction). And a video laryngoscope system for emergency rescue, and an emergency rescue method using the same, capable of instructing the emergency patient to intubate the laryngoscope for the emergency patient by monitoring the condition of the emergency patient based on the emergency patient monitoring image.

In general, the laryngoscope is an emergency measure for a patient who is unconscious due to an accident or other cause. When it is necessary to perform artificial respiration using an artificial ventilation device, the intubation tube and the intubation tube connected to the ventilation device are secured by securing the patient's airway. It is used as an auxiliary device for inserting the tip of the same tube member into a target site such as a patient's organ. Therefore, in general, the laryngoscope is a first aid tool used to maintain the airway by inserting it into the oral cavity of a patient who cannot breathe or a patient with a closed airway.

These laryngoscopes are classified into a general Mackintosh laryngoscope and a video laryngoscope that provides an improved view by mounting a camera on the blade of the laryngoscope.

A typical Macintosh-type laryngoscope consists of a long member with a curved tip, and is inserted through the mouth of a patient who has lost consciousness, and the appropriate part of the side of the tip reaches the root of the tongue and lifts it to secure the patient's airways. Allows insertion of the intubation tube. However, since the Macintosh type laryngoscope relies on the operator's eyes to check the airway structures, there may be limitations in visual field, and sometimes intubation may be delayed or failed due to the inability to confirm important anatomical indicators.

Meanwhile, the video laryngoscope includes a charge-coupled device (CCD) provided at a tip end of a blade for securing an airway, an imaging unit including a lens, and a display unit for displaying an image captured by the imaging unit. This video laryngoscope makes it easier for the operator to observe the patient's pharynx or larynx, and thus facilitates the procedure for the operator to secure the patient's airway and insert the intubation tube. Therefore, in recent years, the use of video laryngoscopes is increasing.

(119 Emergency Rescue Video Laryngoscope System)

1 is a schematic diagram of an emergency rescue method using a 119 emergency rescue video laryngoscope system according to a preferred embodiment of the present invention, and FIG. 2 is a functional conceptual diagram of a 119 emergency rescue video laryngoscope system according to a preferred embodiment of the present invention, 3 is a view showing the display panel of the 119 emergency rescue video laryngoscope system according to a preferred embodiment of the present invention, Figure 4 is based on the oral image in the 119 emergency rescue video laryngoscope system according to a preferred embodiment of the present invention, each It is a diagram showing the corresponding selection of the first blade to the fourth blade suitable for the emergency rescue situation.

Referring to Figures 1 to 4, 119 emergency rescue video laryngoscope system according to a preferred embodiment of the present invention, grip housing, blade, oral camera, oral lighting, display panel, emergency patient monitoring camera, for monitoring photographing It includes a lighting, a communication module unit, a repeater, and a pseudo terminal.

Here, the grip housing is a housing in which a battery is embedded, and is a body housing held by an emergency rescuer. The cross section of the grip housing can be formed in any one of a circular, hemispherical, or polygonal shape, and a plurality of finger-shaped grip groove patterns are formed in a cylindrical shape that can be easily gripped by the operator. It is desirable to be. The grip housing can be stored separately from the blade. Here, the battery provides driving power to an oral camera, a monitoring camera, a display panel, a communication module unit, a temperature sensor, and a heating element. It is also possible to receive power by connecting a display panel to a power source in an ambulance to be described later.

In addition, the blade is a curved frame that can be attached to and detached from the lower end of the grip housing. The blade is inserted into the pharynx or larynx through the patient's oral cavity to secure the patient's airway, and has a structure that is fitted into the detachable groove of the grip housing. The blade is combined with the grip housing to act as an airway intubator, and thus, the video laryngoscope to which the grip housing and the blade are fastened has a “L”-shaped structure. That is, the grip housing forms a stroke in the vertical direction among the "L" characters, and the blade forms a stroke in the horizontal direction among the "L" characters. When the blade is attached to and detached from the grip housing, the coupling for electrical supply and the transmission of an electrical signal, for example, an image signal captured by an oral camera, are simultaneously combined for the electrical signal. Alternatively, when the blade is attached and detached from the grip housing, only the coupling for supplying electricity is made, and the signal transmission of the image signal captured by the oral camera to the display panel may be performed through a separate wired connection.

In addition, the blade is a first blade including a first oral illumination having an illumination angle of 80 degrees or more and a first oral camera having a viewing angle of 80 degrees or more, and a second oral illumination having an illumination angle of 100 degrees or more, and a viewing angle of 100 degrees. A second blade including a second or more oral camera, a third oral illumination having an illumination angle of 120 degrees or more, and a third blade including a third oral camera having a viewing angle of 120 degrees or more, and an illumination angle of 140 degrees or more It includes a fourth blade including a fourth oral camera having 4 oral illumination and a viewing angle of 140 degrees or more.

In addition, according to the instruction received from the doctor's terminal, when the vocal cords are completely visible in the oral image of the emergency patient, the first blade is shown, when only the fibular muscle is seen in the oral image of the emergency patient, the second blade is shown, and only the epiglottis is visible. In case the third blade is not visible, the fourth blade may be replaced and attached to the lower end of the grip housing.

In addition, the oral camera is installed embedded in the outer surface of one side of the tip of the blade to take an image of the patient's oral cavity. By being embedded and installed on the outer surface of the blade, it can have a waterproof function to prevent the penetration of liquid substances such as saliva, saliva, and bleeding into the oral cavity. In addition, the camera takes a picture of the oral cavity of the patient's larynx, pharynx, and trachea, and transmits the corresponding image signal to the image processing unit provided in the grip housing. Therefore, the oral camera is electrically connected to the image processing unit, and the camera may include an image pickup device (eg, CCD), a light source, and a lens. It is desirable that the tip of the blade is made of a transparent material to facilitate the acquisition of oral images.

In addition, the oral lighting is installed on the other side of the tip of the above-described blade so that the oral image of the emergency patient can be photographed to emit light in the direction of the oral cavity of the emergency patient.

In addition, the display panel is installed on the upper end of the grip housing to display an image of the patient's oral cavity taken by the oral camera. The display panel may have an image recording function, an image capture function, and a screen brightness adjustment function according to the operator's selection. It can rotate up and down at the top of the grip housing, and can also rotate left and right at the top of the grip housing. This is to enable the operator to conveniently observe the insertion path of the tube when intubating the tube into the patient's airway using a laryngoscope. The display panel can be rotated up to 210° up and down and 270° left and right, and 180° screen rotation is also possible on the display panel so that the operator can perform the procedure without being limited by space. In addition, the screen in the display panel can be rotated by 180°, so that the practitioner can eliminate the constraints of space and posture discomfort during the procedure. As shown in FIG. 3, it is preferable to use a high color rendering panel as the display panel.

In addition, the emergency patient monitoring camera is installed on the other side of the display panel to shoot the emergency patient monitoring image so that the condition of the emergency patient's face or the area that needs treatment can be monitored, and the monitoring shooting light is used to shoot the emergency patient monitoring image. Thus, it is installed on the other side of the display panel to emit light toward the face of the emergency patient or a region requiring treatment. In the conventional video laryngoscope, there was no concern about the emergency patient monitoring camera or the lighting for monitoring photographing, but in this application, the emergency patient monitoring image and oral image using a camera and lighting for monitoring photographing in order to instruct the laryngoscope intubation from a remote doctor terminal. Was simultaneously transmitted to enable comprehensive judgment.

Here, it is preferable to form a display panel device by integrating a display panel, an emergency patient monitoring camera, and lighting for monitoring photographing. In addition, the display panel device preferably further includes a microphone and a speaker to enable communication with the doctor terminal.

In addition, the display panel device may display an emergency patient monitoring image and an oral image obtained from a monitoring camera using lighting for monitoring photographing, respectively, or simultaneously display through splitting a screen.

In addition, it is preferable that the edge of the display panel device includes a breakage-preventing protruding edge to prevent the video laryngoscope from falling or being damaged by collision while performing emergency rescue. Through this, it prevents unexpected damage to the display panel due to a fall or a collision while moving in an urgent situation where necessary, and as a result, the possibility of use in emergency rescue is improved.

In addition, the communication module unit transmits the oral image of the emergency patient and the state image of the emergency patient to an external doctor terminal by wire or wirelessly through a repeater. Therefore, peripheral devices can access the wireless Internet network to view and store the treatment scene in real time, leaving it for educational and verification data. In particular, when used for educational purposes, accurate and clear screens can be shown to students using each student's terminal.

In addition, it is set to transmit the image captured by the oral camera to surrounding terminals in real time through the communication module unit. Nearby terminals can download and install a pre-distributed mobile app and receive the transmitted image data when accessing the app. For example, if you set up a program to automatically configure a wireless Internet network a few seconds after the operation of the video laryngoscope, and connect to the wireless Internet network with a large screen and a mobile device in the vicinity during product demonstrations at educational places such as medical schools, You can see vivid treatment scenes. Furthermore, it can be implemented so that only the app distributed by the manufacturer of the video laryngoscope can be accessed.

In addition, the blade has a connector module detachable from the lower end of the grip housing, an open bottom and one end surface having a through hole, and a curved body blade having an oral camera fixed therein so as to be photographed through the through hole. , And a tip blade protruding from the end of the body blade in a curved shape, and a cover body covering the open bottom of the body blade. Here, the material of the main blade and the tip blade is made of SUS 316 series stainless steel.

In the present invention, after mounting the oral camera to the position inside the blade, dehumidifying and insulating epoxy work is performed to completely fix the oral camera to have a dustproof dehumidifying effect. To this end, the coupling gap between the blade housing and the cover surface is epoxy-treated so that the inside of the main blade is waterproofed.

Further, in order to increase the performance of the waterproof treatment, it is characterized in that the blade housing and the cover surface are treated with epoxy and then welded with SUS 316 series stainless steel. Therefore, as it is a part that is inserted inside the human body, it is designed to fit the human body with 316 material, and the high-performance oral camera provided inside is completely disconnected from the outside and has a strong characteristic of waterproof and dustproof.

On the other hand, the blades were coated with an anti-fog coating in front of the lens to prevent fogging. However, when the usage time was prolonged, the fogging coating disappeared, and the clear monitor quality could not be seen. Accordingly, the present invention is to remove the fogging phenomenon by heating the lens temperature of the oral camera to the body temperature within 30 seconds inside the blade and maintaining the temperature.

In order to prevent fogging on the lens of the oral camera during oral examination of an emergency patient, the video laryngoscope of the present invention includes a PCB board provided inside a main blade, a temperature sensor mounted on the PCB board to measure temperature, and , It is mounted on the PCB board and includes a heating element for preventing lens fogging of the oral camera by heating the inside of the body blade so that the internal temperature of the body blade becomes the same temperature as the body temperature.

In addition, when examining the patient's oral cavity using a video laryngoscope, the inside of the body blade is heated to a human body temperature (eg, 36.5° C.) so that there is no temperature difference between the oral camera and the human body, and ultimately, the oral camera 400 It is to prevent the occurrence of lens fogging.

In the above, the human body temperature is preset to a preset temperature, for example, 36.5° C., which is a human body temperature, so that the inside of the main blade is maintained at 36.5° C. during operation of the video laryngoscope.

However, since the body temperature is different for each person, maintaining the inside of the body blade with the body temperature fixed at 36.5℃ cannot completely prevent fogging of the oral camera.

Accordingly, a temperature sensor that measures the patient's body temperature on the fly is installed. To this end, the outer surface of the main blade (hereinafter referred to as'the outer surface of the substrate seating') corresponding to the inner surface area of the main blade on which the PCB board is seated (hereinafter, the'substrate seating inner surface') is made of SUS 316 series stainless steel. It is to be coated with a thermally conductive film having a higher thermal conductivity. In addition, the temperature sensor and the thermally conductive film allow heat to be transferred through a via hole filled with a thermally conductive material. Therefore, the temperature sensor can measure the body temperature transmitted through the thermally conductive film.

For example, when taking a picture of the oral cavity while pressing the blade of the video laryngoscope against the patient's tongue, the patient's tongue comes into contact with the blade surface, so that the patient's tongue body temperature reaches the outer surface of the blade's substrate seating. It is transmitted to the temperature sensor through the thermally conductive film, the via hole, and the substrate mounting inner surface in sequence.

On the other hand, in the case of the existing video laryngoscope, only images are implemented on the monitor screen, but the existing products are falling a lot in response to the demands of modern medical professionals that are changing in various ways.

Accordingly, in the present invention, functions such as selectable screen auto-off, standby time selection, and language selection for various countries are incorporated, and a touch screen monitor is mounted to facilitate the operator's convenience. It will be described in detail below.

The display panel of the present invention operates in a standby mode when there is no user operation until a preset waiting time elapses from the user. In this standby mode, when the waiting time elapses, the screen of the display panel is turned off and then the standby notification lamp provided on the display panel is turned on.

In addition, the display panel, as a touch screen panel, may display a language selection interface screen for selecting a language to be used on the touch screen panel to receive a user's touch selection of a language to be used. Therefore, the user can easily select a language that suits them through touch.

In addition, the repeater is configured to connect the communication module unit and the pseudo terminal to enable communication with each other.

In addition, the doctor's terminal monitors the state of the emergency patient based on the oral image of the emergency patient and the emergency patient monitoring image including the emergency patient's face or areas requiring treatment, and provides the emergency rescue personnel at the site. It includes a doctor's terminal in which a laryngoscope intubation instruction is made to a patient.

In addition, the 119 rescue situation room server receives emergency rescue and instructs an ambulance to be dispatched, transmits a standby notification to the doctor terminal of a situation waiting doctor corresponding to the emergency rescue, and matches the video laryngoscope corresponding to the emergency rescue, The emergency patient transmits a notification to the hospital server to be transferred.

In addition, the physiological signal acquisition unit disposed in the ambulance acquires a physiological signal including at least one of respiration, pulse, heart rate, body temperature, oxygen saturation, electrocardiogram, EEG, and EMG of the emergency patient.
