Description

Technical Field

[0001] The utility model relates to the technical field of tracheal intubation, in particular to a controllable bending tracheal intubation combined kit. Background Art

[0002] Endotracheal intubation is a method of inserting a special endotracheal tube through the mouth or nasal cavity and into the trachea or bronchus via the glottis, providing optimal conditions for airway patency, ventilation and oxygen supply, and airway suction. It is an important measure to rescue patients with respiratory dysfunction.

[0003] Difficult airway is a common clinical problem and often threatens patients' lives. With the use of visualization technologies, such as video laryngoscopes and electronic flexible endoscopes, the incidence of difficult airway has been significantly reduced. However, there are still a few difficult airways that cannot be solved with current tools, even with visualization technologies.

[0004] The advent of video laryngoscopes has significantly improved the convenience of laryngoscopy and the success rate of tracheal intubation. The most significant feature of video laryngoscopes is that they incorporate a visual system based on the existing laryngoscope, allowing real-time observation and monitoring of the tracheal insertion process, post-insertion, and during intubation. This improves the operator's convenience and intubation success rate, while reducing the risks of hypoxia and airway damage during intubation.

[0005] In a difficult airway, when the existing video laryngoscope passes through the glottis together with the endotracheal tube, the front end of the endotracheal tube will collide with the glottis, causing glottis damage to the patient and inconvenience in inserting the endotracheal tube. In addition, during the use of the video laryngoscope, due to insufficient lifting of the epiglottis and the natural curvature of the larynx, the endotracheal tube needs to be inserted into the guide tube core and shaped before it can be slid into the glottis. However, this increases the complexity and cost of the endotracheal intubation process, and still cannot achieve the effect of accurate guidance, causing inconvenience to clinical use. In response to the above-mentioned defects, this application is proposed. Utility Model Content

[0006] The utility model aims to provide a controllable bending endotracheal tube combined kit, which uses a controllable bending tube core to adjust the insertion angle and posture of the endotracheal tube, so that the endotracheal tube can be inserted smoothly and reduce damage to the patient.

[0007] In order to solve the above problems, the utility model provides a controllable bending endotracheal tube combined kit, including an endotracheal tube and a controllable bending tube core, the endotracheal tube includes a tube body, a balloon and a guide part, the guide part is arranged on the outside of the balloon, at the distal end of the tube body, the controllable bending tube core includes an operating part, a tube core body, a bending part and a movable part, the movable part is connected to the bending part, the operating part includes an adjusting body and a traction body connected to the bending part, the adjusting body is used to control the traction body to adjust the bending degree of the bending part and control the posture of the movable part, thereby realizing the posture adjustment of the guide part.

[0008] The posture adjustment of the guide part can be achieved through two adjustment methods of the adjustment body. One is to change the bending degree of the bending part through the adjustment body and the traction body to adjust the guide part; the other is to make the controllable bending tube core rotate circumferentially through the adjustment body to adjust the guide part; the two adjustment methods are combined to achieve multi-directional posture adjustment of the guide part.

[0009] When in use, the controllable bending core tube is nested in the traditional endotracheal tube. The controllable bending core tube can manually control the free bending and rotation of the front end of the core tube, thereby driving the free bending of the front end of the endotracheal tube, making the endotracheal tube more smoothly inserted into the glottis, avoiding collision between the front end of the endotracheal tube and the glottis, and minimizing glottis damage.

[0010] It should be noted that the regulating body is not limited to a specific component, and can be multiple components combined with the tube core body, or a part of the tube core body.

[0011] According to an embodiment of the present invention, the adjusting body includes a rotating wheel, the traction body includes at least two traction wires, and the rotating wheel controls the traction wires by rotating.

[0012] According to an embodiment of the present invention, the rotating wheel is provided with an anti-slip structure, such as an anti-slip material, an anti-slip shape, etc.

[0013] Optionally, the rotation axis of the rotating wheel is perpendicular, parallel or colinear with the axis of the tube core body.

[0014] According to an embodiment of the present invention, a joint is installed on the pipe body.

[0015] According to an embodiment of the present invention, the controllably bendable tube core further includes a limiting structure, which is used to limit the maximum depth of the controllably bendable tube core inserted into the endotracheal tube.

[0016] Furthermore, the limiting structure includes a tube core seat installed on the tube core body, the tube core seat is a stepped tube, the thin end of which can be inserted into the joint, and the end surface on the side where the thick end is connected to the thin end constitutes a limiting surface.

[0017] According to an embodiment of the present invention, the curved portion adopts a snake-bone structure or a braided tube structure.

[0018] According to an embodiment of the present invention, the controllable bending endotracheal tube combination kit further includes a video laryngoscope, and the video laryngoscope is provided with a guide groove.

[0019] Furthermore, the video laryngoscope also includes a tongue depressor, a light source and a camera.

[0020] According to an embodiment of the present invention, the guide groove has a side seam, the inner width of the guide groove is greater than the width of the side seam, and the width of the side seam is smaller than the outer diameter of the tube body. At least the structure at the side seam is made of elastic material.

[0021] The beneficial effect of the present invention is that by designing the traditional ordinary endotracheal intubation hard guide wire into a controllable bending tube core, the front end of the endotracheal intubation can be swung or rotated in a controlled manner without the need for pre-shaping, which greatly increases the flexibility of the intubation and the success rate of intubation, and reduces the risks of hypoxia, airway damage, etc. during intubation of patients; by using a video laryngoscope and endotracheal intubation together, the tracheal insertion process, the post-insertion process and the endotracheal intubation process can be observed and monitored in real time, thereby improving the operator's convenience in using the laryngoscope and improving the success rate of intubation.

[0033] The following description is intended only to disclose the present invention and to enable those skilled in the art to implement the present invention. The embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0034] [Example 1]

[0035] Steerable bend endotracheal tube combination kit, such as Figure 3 , including a tracheal cannula 12 and a controllable bending tube core 11, the tracheal cannula 12 and the controllable bending tube core 11 constitute a controllable bending tracheal cannula 1.

[0036] When in use, the controllably bendable core tube 11 is nested in the endotracheal tube 12 .

[0037] like Figure 5 The endotracheal tube 12 includes a tube body 122 , a balloon 123 and a guide portion 124 . The guide portion 124 is located at the distal end of the tube body 122 , and a connector 121 is provided at the proximal end of the tube body 122 .

[0038] Preferably, the connector 121 is provided with a protruding disc-shaped structure to facilitate the gripping of the endotracheal tube 12 during operation.

[0039] like Figure 4 The controllable bending tube core 11 includes an operating part, a tube core body 113, a bending part 114 and a movable part 115, wherein the tube core body 113, the bending part 114 and the movable part 115 are arranged in sequence, and the length of the movable part 115 is generally less than, equal to or greater than the length of the guide part 124, and is preferably less than the length of the guide part 124.

[0040] The bent portion 114 can be an integral structure with the tube core body 113 or bonded to the tube core body 113 . In this solution, the bent portion 114 adopts a snake-bone tube structure.

[0041] The operating part includes an adjusting body 111 and a traction body 116 connected to the bending part 114, wherein the traction body 116 includes at least two traction wires, and the adjusting body 111 includes a rotating wheel, and the traction wires are connected to the rotating wheel. By turning the rotating wheel, the traction wires pull the bending part 114 to bend.

[0042] Preferably, tooth-shaped protrusions are provided on the outer edge of the rotating wheel to form an anti-slip structure.

[0043] In this embodiment, the rotation axis of the rotating wheel is perpendicular to the axis of the tube core body 113, so that the two adjustment modes do not interfere with each other and the operation is convenient.

[0044] Specifically, if Figure 8 、 Figure 10 The posture adjustment of the guide portion 124 can be achieved through two adjustment methods of the adjustment body 111. Figure 8 The first adjustment method is to rotate the wheel to bend the traction wire traction bending portion 114. The structural relationship between the bending portion 114 and the traction wire is as follows: Figure 9 As shown; another Figure 10 As shown, by rotating the adjusting body 111 , the controllably bendable core 11 is caused to rotate circumferentially, thereby adjusting the guide portion 124 ; the two adjusting means are combined to achieve multi-directional posture adjustment of the guide portion 124 .

[0045] Furthermore, in order to facilitate the rotation of the adjustment body 111 and the limiting of the controllable bending tube core 11, the controllable bending tube core 11 also includes a limiting structure, which is used to limit the maximum depth of the controllable bending tube core 11 inserted into the tracheal tube 12. The limiting structure includes a tube core seat 112 installed on the tube core body 113. The tube core seat 112 is a stepped tube, and its thin end can be inserted into the joint 121. The end face on the side where the thick end is connected to the thin end constitutes a limiting surface.

[0046] When the controllably bendable tube core 11 is rotated circumferentially, the operation can be performed through the tube core seat 112 or the rotating wheel, and the limiting surface contacts the joint 121 to achieve limiting.

[0047] Example 2:

[0048] On the basis of Example 1, Figure 1 The controllable bending endotracheal intubation combined kit also includes a video laryngoscope 2, on which a guide groove 21 is provided.

[0049] like Figure 2 The main structure of the video laryngoscope 2 can be the same as that of a traditional video laryngoscope, such as a tongue depressor 22, a visual system, etc. The visual system generally includes a light source 23, a camera 24, and a display component.

[0050] In this embodiment, Figure 6 、 Figure 7 The video laryngoscope insertion portion is provided with a guide groove 21, which is designed with an insertion port 211, a side slit 213, and a guide outlet 214. The controllable bendable endotracheal tube 1 enters through the insertion port 211. The insertion port 211 gradually narrows from the proximal end to the distal end in the insertion direction, forming a trumpet-shaped opening, which facilitates the entry of the controllable bendable endotracheal tube 1.

[0051] The guide groove 21 is designed with side edges 212 extending outward, and the two side edges form side seams 213 relative to each other. The function of the side seams 213 is to prevent the tracheal cannula from sliding out of the guide groove 21 during the insertion of the controllably bendable tracheal cannula 1. The width S of the side seams 213 is less than the internal height H of the guide groove 21, and the internal height H of the guide groove is slightly larger than the outer diameter of the tracheal cannula. This design enables the tracheal cannula to be inserted into the guide groove more smoothly without falling out of the guide groove.

[0052] Preferably, the guide groove 21 has a certain elastic deformation capability, and the width S of the side seam 213 can be elastically increased. When the endotracheal tube needs to be separated from the guide groove, it is only necessary to pull the endotracheal tube out from the side seam with a little force. The guide outlet can guide the endotracheal tube to the glottis.

[0053] Usage steps: When the doctor uses the video laryngoscope to perform tracheal intubation, first Figure 1 The video laryngoscope is placed in the patient's mouth, and a tongue depressor is used to lift the epiglottis, exposing the glottis. The video laryngoscope's visual system captures the image and displays it on a monitor. A steerable, flexible endotracheal tube is then inserted into the guide slot and advanced manually or electronically until it reaches the front of the glottis. The wheel is then rotated to drive the active portion of the steerable, flexible endotracheal tube to swing and rotate, directing the tube's guide toward the glottis. Finally, the tube is manually or electronically inserted into the glottis until it stops at the appropriate position. The tube is then left in place, and the video laryngoscope and steerable, flexible tube stylet are removed, completing the endotracheal intubation procedure.

[0054] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments. Any variations and modifications may be made to the embodiments of the present invention without departing from the principles described.
