Technical Field

[0001] This utility model relates to the field of visual intubation, and more specifically, to a endotracheal intubation device. Background Technology

[0002] Flexible video laryngoscopes combine the flexibility of electronic bronchoscopes with the wide field of view of rigid video laryngoscopes, greatly improving the ease of endotracheal tube insertion using video laryngoscopes.

[0003] When using a flexible video laryngoscope for endotracheal intubation, the endotracheal tube needs to be inserted into the pharynx along the scope of the flexible video laryngoscope, which is a relatively complicated procedure.

[0004] Therefore, how to provide an endotracheal intubation device that can effectively improve the convenience of endotracheal intubation has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] One objective of this invention is to provide a new technical solution for an endotracheal intubation device that can effectively improve the convenience of endotracheal intubation.

[0006] According to a first aspect of the present invention, an endotracheal intubation device is provided.

[0007] The endotracheal intubation device includes a flexible video laryngoscope and an auxiliary intubation mechanism; among which,

[0008] The flexible video laryngoscope includes a laryngoscope body, a display unit, and a first handle. The laryngoscope body and the display unit are both connected to the first handle. The laryngoscope body includes a flexible section. A tongue depressor and a first camera unit are provided at the end of the flexible section away from the first handle. A first driving component is provided on the first handle. The first driving component is used to drive the flexible section to bend within a preset angle range.

[0009] The auxiliary intubation mechanism includes a core and a second handle. The core is used to cooperate with the endotracheal tube. The core is connected to the second handle. The core includes a deformable section. A second camera unit is provided on the end of the deformable section away from the second handle.

[0010] The display unit is configured to display images captured by the first camera unit and images captured by the second camera unit.

[0011] Optionally, the first drive assembly includes a first drive element, which is an angle trigger, a knob, or a lever.

[0012] Optionally, the core is provided with a tracheal tube positioning part, which is configured to cooperate with the tracheal tube to position the tracheal tube on the core.

[0021] The auxiliary intubation mechanism of this utility model can fix the endotracheal tube on the stylet during use, assisting in the insertion of the endotracheal tube. When the flexible video laryngoscope does not fully expose the glottis or cannot expose the glottis, the deformation of the deformable section of the stylet of the auxiliary intubation mechanism can bypass the tissue that obstructs the field of vision, thereby assisting in the exposure of the glottis.

[0022] Other features and advantages of the present invention will become clear from the following detailed description of exemplary embodiments of the present invention with reference to the accompanying drawings. Attached Figure Description

[0023] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments of the present invention and, together with their description, serve to explain the principles of the present invention.

[0024] Figure 1 This is a schematic diagram of an embodiment of the endotracheal intubation device of this utility model.

[0025] Figure 2 This is a schematic diagram of the structure of the second drive component of the endotracheal intubation device of this utility model.

[0026] The diagram is labeled as follows: scope body-1, flexible section-101, tongue depressor-102, display unit-2, first handle-3, tube core-4, deformable section-401, endotracheal tube positioning part-402, second handle-5, first drive component-6, second drive component-8, traction component-9, deformable mechanism-10, and rotating wheel-11. Detailed Implementation

[0027] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0028] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0029] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0030] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0031] like Figure 1 and Figure 2 As shown, the endotracheal intubation device provided by this utility model includes a flexible video laryngoscope and an auxiliary intubation mechanism.

[0032] The flexible video laryngoscope includes a body 1, a display unit 2, and a first handle 3. Both the body 1 and the display unit 2 are connected to the first handle 3. The first handle 3 is used by the operator to conveniently hold the flexible video laryngoscope. The display unit 2 may be, for example, a display screen.

[0033] The mirror body 1 includes a flexible segment 101. At the end of the flexible segment 101 away from the first handle 3, there is a tongue depressor 102 and a first camera unit (not shown in the figure). The flexible segment 101 has deformability.

[0034] The tongue depressor 102 can be fixed to the laryngoscope body 1 by welding or integral molding. When using a flexible video laryngoscope equipped with the tongue depressor 102, after the epiglottis is visualized by the first camera unit on the laryngoscope body 1, the tongue depressor 102 is inserted into the vallecula or below the epiglottis, and then the epiglottis is lifted to expose the glottis. Furthermore, during insertion into the oropharyngeal cavity, the flexible video laryngoscope equipped with the tongue depressor 102 increases the field of view at the tip of the laryngoscope, making it easier to identify the structures of the oropharyngeal cavity.

[0035] The first camera unit can be, for example, a camera with a light source. The first camera unit can acquire an image of the front end of the mirror body 1.

[0036] The image captured by the first camera unit can be observed through the display unit 2, thereby accurately realizing the operation of visual intubation.

[0037] The first handle 3 is provided with a first driving component. The first driving component is used to drive the flexible segment 101 to bend within a preset angle range. During the insertion of the flexible video laryngoscope, after the epiglottis is seen through the first camera unit, the first driving component causes the flexible segment 101 at the front of the laryngoscope 1 to bend upward towards the epiglottis, thereby causing the tongue depressor 102 to tilt upward, so as to lift the epiglottis and expose the glottis.

[0038] In specific implementation, the first driving component can adopt a structure well known in the art to drive the flexible segment. For example, the first driving component includes a driving member, a rotating wheel, a traction member, and a snake bone. By controlling the driving member to rotate the rotating wheel, the rotating wheel pulls the traction member to bend the snake bone, thereby enabling the tongue depressor 102 to swing with the flexible segment 101, thus lifting the epiglottis and other pharyngeal tissues.

[0039] The auxiliary intubation mechanism includes a stylet 4 and a second handle 5. The stylet 4 is used to engage with the endotracheal tube. The stylet 4 can be engaged with the endotracheal tube by means of snap-fit ​​or threaded connection, so that the endotracheal tube is secured to the stylet 4.

[0040] The core 4 is connected to the second handle 5. The second handle 5 is used by the operator to conveniently hold the auxiliary cannulation mechanism.

[0041] The die 4 includes a deformable section 401, and a second camera unit (not shown in the figure) is provided on the end of the deformable section 401 away from the second handle 5. The second camera unit may be, for example, a camera with a light source. An image of the front end of the die 4 can be acquired through the second camera unit.

[0042] The deformable segment 401 can be achieved in various ways. For example, the deformable segment 401 can be a malleable segment made of a material such as metal that can be deformed under external force. By shaping the deformable segment 401 into the desired shape outside the body, it can bypass tissues that obstruct the field of vision, thereby assisting in the exposure of the glottis. Alternatively, the deformable segment 401 can be deformed by a second drive assembly with a similar structure to the first drive assembly. This second drive assembly includes a drive member, a traction member, and a deformation mechanism. By controlling the drive member to pull the deformation mechanism, the deformation mechanism can be bent, allowing the front end of the core 4 to change position as the deformation mechanism bends, thereby bypassing tissues that obstruct the field of vision and assisting in the exposure of the glottis.

[0043] The display unit 2 is configured to display the images captured by the first camera unit and the second camera unit, so that not only the images captured by the lens 1 can be observed on the display unit 2, but also the images captured by the core 4.

[0044] The endotracheal intubation device of this utility model is used as follows:

[0045] First, the flexible video laryngoscope 1 is inserted into the pharyngeal cavity, and the glottis is exposed using conventional methods. Then, the stylet 4 of the auxiliary intubation mechanism, which incorporates an endotracheal tube, is inserted into the glottis. The endotracheal tube is then separated from the stylet 4, and pushed into the trachea along the stylet 4. When the flexible video laryngoscope does not fully expose the glottis or cannot expose it at all, the stylet 4 of the auxiliary intubation mechanism, through the deformation of its deformable section 401, bypasses tissues obstructing the view and locates the glottis with the assistance of a second camera unit.

[0046] The auxiliary intubation mechanism of this utility model can fix the endotracheal tube on the core 4 during use, assisting in the insertion of the endotracheal tube. When the flexible video laryngoscope does not fully expose the glottis or cannot expose the glottis, the deformation of the deformable section 401 of the core 4 of the auxiliary intubation mechanism can bypass the tissue that obstructs the field of vision, thereby assisting in the exposure of the glottis.

[0047] In one embodiment of the endotracheal intubation device of this utility model, the first driving component includes a first driving member 6, which is an angle trigger, a knob or a lever.

[0048] In practice, the angle trigger is rotatably connected to the first handle 3, and the angle trigger can also be fixedly connected to one end of the traction member. Thus, rotating the angle trigger causes the traction member to bend the flexible segment 101. The knob is threadedly connected to the first handle 3. Turning the knob in and out of the first handle 3 changes the length of the traction member, thereby achieving the bending of the flexible segment 101. The pressure rod is rotatably connected to the first handle 3, and the pressure rod can also be fixedly connected to one end of the traction member. Thus, applying force to the pressure rod causes the traction member to bend the flexible segment 101. The rotary knob and pressure rod can be used to replace the angle trigger.

[0049] In one embodiment of the endotracheal intubation device of this utility model, the core 4 is provided with an endotracheal tube positioning part 402. The endotracheal tube positioning part 402 is configured to cooperate with the endotracheal tube to position the endotracheal tube on the core 4. The endotracheal tube positioning part 402 may be, for example, a snap-fit ​​or a thread, to cooperate with the endotracheal tube by means of snap-fit ​​or threaded connection, so that the endotracheal tube is fixed on the core 4.

[0050] In one embodiment of the endotracheal intubation device of this utility model, the second handle 5 is further provided with a second driving assembly, which is used to drive the deformable segment 401 to bend within a preset angle range. By controlling the deformation of the deformable segment 401 through the second driving assembly, it bypasses tissues that obstruct the field of vision, thereby assisting in the exposure of the glottis.

[0051] Furthermore, the second drive assembly includes a second drive member 8, at least one traction member 9, and a deformation mechanism 10. The second drive member 8 may be, for example, an angle trigger, a knob, or a lever. The traction member 9 may be, for example, a traction rope. The deformation mechanism 10 may be, for example, a snake skeleton. The deformation mechanism 10 is disposed in the deformation section 401, and the two ends of the traction member 9 are respectively connected to the second drive member 8 and the deformation mechanism 10.

[0052] The user can control the second driving component 8 to make the traction component 9 pull the deformation mechanism 10 to bend, so that the front end of the tube core 4 can change position as the deformation section 401 bends, thereby bypassing tissues that obstruct the view and assisting in exposing the glottis.

[0053] Furthermore, the second drive assembly also includes a rotating wheel 11, and the second drive member 8 is connected to the rotating wheel 11. One end of the traction member 9 is connected to the deformation mechanism 10, and the other end of the traction member 9 is connected to the rotating wheel 11.

[0054] In specific implementation, the traction member 9 may include a first traction member and a second traction member, which are disposed on both sides of the deformation mechanism 10. The second driving member 8 is connected to the rotating wheel 11, and the ends of the first and second traction members away from the deformation mechanism 10 are respectively connected to opposite sides of the rotating wheel 11. When force is applied to the second driving member 8, the second driving member 8 can drive the rotating wheel 11 to rotate. When the second driving member 8 is pulled upward, the rotating wheel 11 rotates clockwise. At this time, the first traction member located on the left side of the deformation mechanism 10 is tightened, causing the deformation mechanism 10 to bend to the left, and the deformation segment 401 bends to the left simultaneously. When the second driving member 8 is pulled downward, the rotating wheel 11 rotates counterclockwise. At this time, the second traction member located on the right side of the deformation mechanism 10 is tightened, causing the deformation mechanism 10 to bend to the right, and the deformation segment 401 bends to the right simultaneously. Thus, by pulling the traction members on both sides of the deformation mechanism 10, the front end of the tube core 4 is bent, thereby bypassing tissues that obstruct the field of vision to assist in exposing the glottis.

[0055] Furthermore, the laryngoscope body 1 is provided with a guide channel (not shown in the figure). The guide channel is located on the outer wall surface of the laryngoscope body 1 and extends along the length of the laryngoscope body 1. By controlling the second driving member 8 to cause the traction member 9 to pull the deformation mechanism 10 to bend, the front end of the stent 4 of the auxiliary intubation mechanism can move within the guide channel, so that the stent 4 of the auxiliary intubation mechanism can move along the flexible video laryngoscope in a more controllable manner.

[0056] The aforementioned guide channel can be a groove-like structure directly formed on the outer wall surface of the mirror body 1. Alternatively, the aforementioned guide channel can be a tubular structure attached to the outer wall surface of the mirror body 1 (this tubular structure usually has a certain degree of elasticity). Or, the aforementioned guide channel can be a guide tube fixed within a groove-like structure on the outer wall surface of the mirror body 1.

[0057] Furthermore, the guide channel is provided with a slit or notch extending along the length of the guide channel, through which the core 4 can be easily removed from the guide channel.

[0058] In one embodiment of the endotracheal intubation device of this invention, the endoscope 1 and / or the core 4 are further provided with a suction channel and / or a ventilation channel. The suction channel can be used to remove contaminants, and the ventilation channel can be used to supply air and / or administer medication.

[0059] The suction channel can be used to drain secretions, blood, and other contaminants from the oropharyngeal cavity. Contaminants can enter the suction channel through its inlet (usually located at the front end of the endoscope 1 or the front end of the stylet 4). The outlet of the suction channel can be located on the first handle 3 or the second handle 5, and contaminants can exit the flexible video laryngoscope or auxiliary intubation mechanism through the outlet of the suction channel.

[0060] The ventilation channel can be used to deliver oxygen or local anesthetic drugs. The inlet of the ventilation channel can be located on the first handle 3 or the second handle 5, and the outlet of the ventilation channel can be located at the front end of the endoscope 1 or the front end of the stylet 4.

[0061] In one embodiment of the endotracheal intubation device of this invention, the second camera unit is wired or wirelessly connected to the display unit 2 to transmit the shooting signal of the second camera unit to the display unit 2. In this way, the display unit 2 can simultaneously display the images captured by the first and second camera units, greatly improving the convenience of using the endotracheal intubation device.

[0062] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
