Laryngoscopes with Removable Endoscope Guides

The present invention relates to a laryngoscope having a removable endoscope guide, and more particularly, to a laryngoscope providing an endoscope guide so that the endoscope can be easily installed in a commonly used laryngoscope.

Laryngoscopes are medical devices used for intubation in the trachea to maintain a person's respiratory tract. The intubation of the patient without artificially maintaining the airway is an important medical procedure directly related to life, and is used for anesthesia surgery, critical care and emergency care.

The laryngoscope, which is essential for respiratory airway management, is a device that is used to secure airway obstruction, aspiration prevention, and respiratory passages. The endotracheal intubation method uses a laryngoscope to mount an endotracheal tube into the trachea. The process of laying is done.

In general, tracheal intubation is often used in medically important situations. The conventional tracheal intubation method using an endotracheal intubation uses a method of securing the airway visually through a common laryngoscope and inserting an endotracheal intubation into the trachea. In this case, when the laryngoscope is inserted or the tube is inserted, the visual field is not properly secured, and when the field of vision is not easily secured, the inexperienced beginners may damage the patient's teeth with the laryngoscope or insert the tracheal intubated by force. Complications can also cause sore throat, so many difficulties are involved in the procedure.

Therefore, when the tube is inserted into the laryngoscopy or trachea, there is a need for an operator to secure a more accurate field of view than a naked eye procedure using a conventional laryngoscope. However, this requires costly inconvenience, such as the use of expensive and completely new equipment.

Accordingly, the technical problem of the present invention is conceived in this respect, the object of the present invention is to provide a laryngoscope having an endoscope guide that can be easily intubated by detachable endoscope using an existing general type laryngoscope. .

The laryngoscope according to an embodiment for achieving the above object of the present invention includes a body portion, a blade, a connecting portion, an endoscope guide, an endoscope, and a display device. The torso may be held by the user. The blade is inserted into the mouth of the patient to maintain a space for securing the airway. The connecting portion connects the body portion and the blade. The endoscope guide is coupled to the blade detachably. The endoscope is inserted into the endoscope guide to take an image of the patient's mouth. The display device is attached to the body portion and outputs an image transmitted from the endoscope. The blade includes a blade coupling portion connected to the connection portion, a main plate formed in the vertical direction and a fixed plate formed in the horizontal direction at the bottom of the blade to fix the tongue of the patient. The endoscope guide is a guide body portion connected along the main plate of the blade in the longitudinal direction, a guide coupling portion attached to the corner portion corresponding to the corner connected to the main plate of the fixed plate of the blade, the guide body portion and And a guide hole connecting the guide coupling part, the guide bottom part connected along the fixing plate of the blade, and a suction hole through which the suction tube can pass. The guide coupling portion of the endoscope guide is formed by a coupling groove that is coupled along one edge of the fixing plate of the blade is removable.

In one embodiment, the endoscope includes a cable for transmitting an image signal, the connection portion may include a connection for connecting the cable.

In an embodiment, the apparatus may further include an image storage device capable of storing an image transmitted from the endoscope.

In one embodiment, the display device includes a screen for outputting an image and a display device connection portion for connecting with the body portion, and on the display device connection portion or the screen of the display device so that a user can easily operate with one hand. The operation unit may be included in the space between the connector and the connection unit.

In one embodiment, the endoscope guide is formed with an endoscope hole formed in the direction in which the blade extends through the guide body portion, the endoscope may be inserted through the endoscope hole.

According to the present invention described above, it is possible to see the situation in the mouth of the patient taken through the endoscope through the display device only by attaching the laryngoscope guide of the present invention to a commonly used laryngoscope, which is superior to visual observation. Good visibility. Therefore, even in the case of a novice, the tracheal intubation of the patient can be performed while checking the image in the oral cavity of the patient through the display device in an emergency. In particular, children and infants who have difficulty in securing a small field of view may use it well.

In addition, since the endoscope guide can be simply attached and used in the existing equipment, it can be demonstrated at a low price. The laryngoscope system, which was newly manufactured including the endoscope, was not very easy because it was very expensive equipment.

In addition, since the general laryngoscope can be used as it is, there is an advantage that the practitioner who was used to the existing equipment can be easily applied in the field without having to practice again for the new equipment.

In addition, since the endoscope guide is easily detachable from the laryngoscope, it can be easily washed after the procedure, there is an advantage in the disinfection of the laryngoscope.

In addition, a separate image storage device can be attached to preserve the patient's procedure records like a black box, so that these images can be used later to verify the procedure and check the patient's mouth or airway. do.

Finally, when detaching the endoscope guide of the present invention immediately returns to the general laryngoscope, the endoscope is not required, or in special circumstances there is an advantage that can be used immediately without using the endoscope.

Hereinafter, with reference to the accompanying drawings, it will be described in detail the present invention.

Referring to Figure 1, the laryngoscope according to an embodiment of the present invention is a body 120 that can be held by the user, the blade 120 is inserted into the mouth of the patient to maintain a space for airway, the body Connecting portion 115 for connecting the blade and the blade, the endoscope guide 130 is coupled to detachable to the blade, the endoscope is inserted into the endoscope guide to photograph the oral cavity of the patient 150 and attached to the body And a display device 140 for outputting an image transmitted from the endoscope.

The three components of the torso 110, the connecting portion 115, and the blade 120 are identical to the components of the laryngoscope which are commonly used. The torso 110 may include a concave-convex pattern on the surface so that the operator can easily hold, the blade 120 may have a variety of sizes and shapes according to the situation or age of the patient. The connection portion 115 includes a structure that can be separated from the blade 120 to facilitate the exchange of the blades manufactured in various types. In addition to these three components, another laryngoscope in one embodiment of the present invention includes an endoscope guide 130 that can be easily installed in a general laryngoscope.

The laryngoscope of the present invention directly photographs the intraoral image of the patient through the endoscope 150 and shows it to the operator through the display device 140. To this end, the endoscope guide 130 fixes the endoscope 150 therein through an endoscope hole 135 formed therein, and the endoscope guide 130 itself is fixed to the lower portion of the blade 120. . Therefore, the commonly used laryngoscope can be performed while checking the image in the oral cavity with a separate display device, and the difficulty of using the completely new type of equipment by the operator who is used to the existing equipment can be minimized. have.

The endoscope hole 135 is formed through the guide body 131 of the endoscope guide 130 to be described later, in this case, the endoscope hole 135 is the coupling groove 137 is the blade 120 It is formed along the extended direction. Thus, the endoscope 150 may be inserted through the endoscope hole 135 to extend to the ends of the blade 120 and the endoscope guide 130, and to easily capture an image of the patient's mouth. It becomes possible.

In addition, the endoscope guide 130 may be generally made of a plastic material or the like used in medical devices. In order not to affect the center of gravity of the laryngoscope itself so as not to create discomfort to users familiar with the underlying laryngoscope, it may be formed of a relatively light material, and is generally coupled and fixed to the latter side of the blade 120, The length of the blade 120 may be less than half.

Since the endoscope guide 130 is formed to be detachable from the blade 120, it can be separated and disinfected for disinfection and the like after the procedure. Similarly, since the endoscope 150 is fixed in the hole through the endoscope hole 135, detachment and individual disinfection are possible with the endoscope 150.

FIG. 2 is a schematic rear view illustrating the laryngoscope of FIG. 1. In Figure 2 it can be seen that the blade 120 and the endoscope guide 130 of the laryngoscope in accordance with an embodiment of the present invention is connected.

Referring to FIG. 2, the blade 120 has a blade coupling portion 121 directly connected to the connection portion 115 and a main plate formed in a vertical direction under the connection portion 115 connected to the body portion 110. 123 and a fixing plate 125 formed in a horizontal direction at the bottom of the blade to fix the tongue of the patient. The main plate 123 divides the patient's oral cavity in the left and right directions, fixes the tongue in the oral cavity to one side, and serves to secure a space for intubation, a space for securing a field of view, and the like. In the case of the blade 120 shown in FIG. 2, the tongue of the patient is positioned on the left side of the blade and the tube is inserted to the right. The fixing plate 125 is connected to the mail plate 123, and is formed only in one direction so that the patient's tongue does not come out downward and serves to fix the patient's tongue in one direction.

Endoscopic guide 130 of the laryngoscope according to an embodiment of the present invention is formed in a form surrounding the fixed blade 125. The endoscope guide 130 includes a fixing groove 137 that can wrap the fixing blade 125 for this purpose. Specifically, the endoscope guide 130, the endoscope guide is a guide body portion 131 is connected along the main plate 123 of the blade in the longitudinal direction, the main plate of the fixed plate 125 of the blade ( The guide coupling portion 139 attached to the corner portion corresponding to the corner connected to the 123 and the guide body portion and the guide coupling portion, and the guide bottom portion 133 connected along the fixing plate 125 of the blade It includes. The guide coupling portion 139 of the endoscope guide is formed with a coupling groove 137 coupled along one edge of the fixed plate of the blade.

The guide body 131 of the endoscope guide 130 is wrapped around the other side of the main plate 123 and fixed. The main plate 123 and the fixing plate 125 of the blade 120 are substantially fixed as a whole. Sliding movement in the front direction of the blade 120 in the rear portion of the blade 120 may be coupled or separated along the coupling groove 137.

In addition, since the endoscope guide 130 must secure a space for intubation even after the endoscope guide 130 is coupled to the blade 120, the endoscope guide 130 is formed to maintain a relatively narrow space in the horizontal direction. The endoscope guide 130 does not take the width wider than necessary except for the space for providing the groove 135 to which the endoscope 150 can be fixed.

The endoscope guide 130 should be manufactured to correspond to the shape of the blade 120 for coupling. Therefore, in the case of a general laryngoscope, a laryngoscope is used that can be replaced with another blade according to the age and oral structure of the patient. In this case, the endoscope guide 130 may be separately manufactured to suit the shape of the blade 120. Since the endoscope guide 130 is a structure that can be separated from the endoscope 150 and the blade 120, respectively, there is an advantage that can be used immediately assembled.

In addition, since the portion of the blade 120 is coupled to the endoscope guide 130 relatively does not affect the procedure, for this purpose, the coupling portion of the blade 120 can be manufactured in a predetermined form. In this case, there is a disadvantage in that the existing laryngoscope 120 cannot be directly applied.

3 is a schematic side view illustrating the laryngoscope of FIG. 1.

Referring to FIG. 3, the laryngoscope according to another embodiment of the present invention has a body portion 110, a blade 120, a connection portion 115, an endoscope guide 130, and an endoscope 150 as in the embodiment shown in FIG. 1. ) And the display device 140.

The laryngoscope according to the present embodiment includes a connection part 165 to which the cable 160 for image transmission of the endoscope is connected to the connection part 115. When the cable 160 connected to the endoscope 150 is extended for a long time, it may be disturbed when a separate tube is inserted into the mouth of the patient. Therefore, since the length of the cable 160 is shortened and a video image is transmitted, the procedure can be performed relatively freely during the procedure.

When the installation is possible, the connection portion may be formed in the blade 120, but the blade 120 is generally manufactured in a plate shape, and thus it is not easy to provide a space for a separate connection portion. Therefore, although the connection part 165 is formed on the connection part 115, if this is not possible, the connection part 165 may be formed on the body part 110. Through this, the operator can freely perform the procedure from the interference of the cable 160 during the procedure, and can prevent the damage of the cable and the failure of the display device according to the procedure. In the case of the laryngoscope according to the present invention, since only the display device is viewed and operated, it may be dangerous when the display device is turned off in the middle, so it is important to secure the stability of the cable 160.

Referring to FIG. 4, the laryngoscope according to another embodiment of the present invention has a body portion 110, a blade 120, a connection portion 115, an endoscope guide 130, and an endoscope 150 as in the embodiment shown in FIG. 1. ) And the display device 140.

In the present embodiment, the suction hole 170 may be connected to the endoscope guide 130 so that the suction can be simultaneously operated when the laryngoscope is intubated. The length and direction of the suction tube 170 can be variously adjusted according to the situation, and in particular, when foreign materials such as blood in the oral cavity are inserted to prevent the endoscope 150 from being photographed, thereby preventing the recording of the endoscope 150. Can be used.

In the present exemplary embodiment, the display device 140 allows the user to easily control the position of the operation unit 147 capable of controlling the endoscope 150 and other suction functions with one hand. The display device 140 may be formed on the display device connection part 145 connecting the body part 110 or in a space between the screen 141 and the connection part of the display device 140.

Since the operator must fix the laryngoscope with one hand and hold the patient's mouth or the tube for intubation with the other hand, it is difficult to use the other hand when the endoscope needs to be operated separately. Therefore, the operation unit 147 can be arranged at a position where operation is easy. The operation unit 147 may control the storage (recording) of the image, the partial enlargement / reduction of the image, the operation control of the suction device, and the like. Helps to ease the treatment and at the same time.

Although described above with reference to the embodiments, those skilled in the art can be variously modified and changed within the scope of the invention without departing from the spirit and scope of the invention described in the claims below. I can understand.

As described above, according to the embodiment of the present invention, by simply attaching the laryngoscope guide of the present invention to the laryngoscope generally used, the situation in the mouth of the patient taken through the endoscope can be viewed through the display device. Compared with the conventional naked eye procedure, even a beginner can easily secure an airway and intubate.

In addition, the endoscope guide is easily removable from the laryngoscope, so that it can be easily washed after the procedure, and also easy to clean and disinfect the laryngoscope, and to preserve the patient's procedure record through a separate image storage device attached, There is an advantage that can be utilized in various ways.
