Description

Technical Field

[0001] The utility model relates to the field of visual intubation, and more specifically, to a soft visual laryngoscope and a tracheal intubation device. Background Art

[0002] The soft video laryngoscope has the advantages of both the flexibility of an electronic bronchoscope and the wide field of view of a rigid video laryngoscope, but it usually requires the use of a guiding structure to guide the tracheal tube when used in conjunction with tracheal tube intubation.

[0003] One of the existing ways of cooperating between a flexible video laryngoscope and a guide structure is to set a C-shaped guide groove on the body of the flexible video laryngoscope, and guide the endotracheal tube through a guide tube matched with the C-shaped guide groove. However, during the use of the flexible video laryngoscope, the curved section of the body will bend and deform, and the inner diameter of the C-shaped guide groove will change due to the deformation when the curved section of the body bends, thereby affecting the smoothness of the guide tube moving along the guide channel.

[0004] In order to prevent the C-shaped guide groove from deforming during the use of the soft video laryngoscope and seriously affecting the smooth movement of the guide tube, it is necessary to strictly control parameters such as the groove size and position of the C-shaped guide groove, resulting in high production requirements, difficulty and cost for the C-shaped guide groove.

[0021] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the present invention and, together with the description, serve to explain the principles of the present invention.

[0022] Figure 1 It is a schematic structural diagram of an embodiment of the soft visual laryngoscope of the utility model.

[0023] The following are marked in the figure:

[0024] Mirror body-1, bending section-11, insertion section-12, support section-13, handle-2, guide channel-3, guide channel body-30, bending guide section-301, insertion guide section-302, support guide section-303, flaring section-304, tongue depressor-4. DETAILED DESCRIPTION

[0025] 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 arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0026] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0027] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0028] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0029] like Figure 1 As shown, the soft video laryngoscope provided by the utility model comprises a mirror body 1 and a handle 2. The mirror body 1 may be composed of an insertion section 12, a bending section 11 and a support section 13 arranged in sequence. A lens assembly is provided at the end of the insertion section 12. The support section 13 is connected to the handle 2. A display screen may be connected to the handle 2, and a control member for controlling the deformation of the bending section 11 may be provided. The control member may be, for example, an angle trigger.

[0030] A guide channel 3 is provided on the outer surface of the mirror body 1. The guide channel 3 includes a curved guide segment 301 corresponding to the curved segment 11 of the mirror body 1, and at least the curved guide segment of the guide channel has no opening in the circumferential direction. Since the curved guide segment 301 is not a C-shaped structure, when the curved guide segment 301 is bent and deformed along with the curved segment 11, the inner diameter of the curved guide segment will not be significantly changed due to the bending, and it is not easy to affect the smoothness of the guide tube moving along the guide channel 3.

[0031] The guide channel 3 can be fixed on the outer surface of the mirror body 1 by means of gluing, plastic welding, clamping, sleeve connection, etc. Different sections of the guide channel 3 can be fixed on the mirror body 1 by different fixing methods. For example, the curved guide section 301 of the guide channel 3 is fixed on the curved section 11 by gluing, and the sections at both ends of the curved guide section 301 are fixed on the mirror body 1 by means of buckle fixing or are integrally formed with the mirror body.

[0032] The curved guide section 301 of the guide channel 3 of the soft visual laryngoscope provided by the utility model has a complete structure without openings, is not easily deformed when the mirror body 1 is bent, is simple to manufacture, and has a low manufacturing cost.

[0033] When the soft visual laryngoscope of the utility model is used, the insertion section 12 of the body 1 of the soft visual laryngoscope can be first placed in the oral cavity, and the angle trigger on the handle 2 can be pulled to push the insertion section 12 forward while lifting the tongue and pharyngeal cavity tissue, and the lens assembly at the front end of the insertion section 12 can transmit the image in the oropharyngeal cavity to the display screen in real time. After the insertion section 12 or the tongue depressor 4 exposes the glottis, the guide tube or tracheal tube is inserted into the glottis through the guide channel 3, and then the soft visual laryngoscope is withdrawn.

[0034] In one embodiment of the soft video laryngoscope disclosed herein, in order to simplify the structure of the guide channel 3 , reduce the manufacturing difficulty and control the manufacturing cost, the entire guide channel 3 has no openings in the circumferential direction.

[0035] In one embodiment of the soft video laryngoscope disclosed herein, the guide channel 3 further includes an insertion guide section 302 and a support guide section 303. The insertion guide section 302 corresponds to the insertion section 12 of the mirror body 1, and the support guide section 303 corresponds to the support section 13 of the mirror body 1. The insertion guide section 302, the bending guide section 301 and the support guide section 303 are arranged in sequence. The insertion guide section 302 and the support guide section 303 can be bonded and fixed to the mirror body 1, or the insertion guide section 302 and the support guide section 303 are snap-connected to the mirror body 1, or the insertion guide section 302 and the support guide section 303 are integrally formed with the mirror body 1.

[0036] In a specific implementation, the guide channel 3 can be fixed or connected to the mirror body 1 only by inserting the guide segment 302 and the supporting guide segment 303, while there may be no fixed or connected relationship between the bending guide segment 301 and the bending segment 11 of the mirror body 1. The bending guide segment 301 and the bending segment 11 are in a separated state to more effectively avoid deformation of the bending guide segment 301 when the mirror body 1 bends.

[0037] In one embodiment of the flexible video laryngoscope of the present invention, a flared portion 304 is provided at the inlet end of the guide channel 3, and the inner diameter of the flared portion 304 gradually decreases in the direction away from the inlet end of the guide channel 3. The flared portion 304 may be funnel-shaped or trumpet-shaped. In specific implementation, the flared portion 304 may be provided on the body 1 of the flexible video laryngoscope or on the handle 2 of the flexible video laryngoscope. The guide tube or tracheal tube may enter the guide channel 3 conveniently and quickly through the flared portion.

[0038] In one embodiment of the flexible video laryngoscope of the present invention, a deflection guide portion (not shown) is provided at the outlet end of the guide channel 3, and the extension direction of the deflection guide portion is toward the central axis of the mirror body 1. The deflection guide portion can guide the guide tube or tracheal tube extending from the outlet of the guide channel 3 to the central axis of the flexible video laryngoscope, so that the guide tube or tracheal tube can enter the glottis more smoothly. In specific implementation, the outlet of the deflection guide portion can be flush with the end of the mirror body 1 of the flexible video laryngoscope, or the outlet of the deflection guide portion can extend out of the end of the mirror body 1 of the flexible video laryngoscope.

[0039] In one embodiment of the soft video laryngoscope of the present utility model, a suction channel (not shown in the figure) and a ventilation channel (not shown in the figure) are provided in the soft video laryngoscope. The inlet of the suction channel and the outlet of the ventilation channel are both located at the front end of the body 1 of the soft video laryngoscope.

[0040] The entrance of the suction channel refers to the entrance of contaminants such as secretions and blood in the oropharyngeal cavity, and contaminants can enter the suction channel from the entrance of the suction channel. The outlet of the suction channel can be located on the handle 2 of the soft visual laryngoscope, and contaminants can leave the soft visual laryngoscope from the outlet of the suction channel. The outlet of the ventilation channel refers to the outlet of the gas in the ventilation channel, and oxygen or local anesthetic drugs can enter the oropharyngeal cavity from the outlet of the ventilation channel. The entrance of the ventilation channel can be located on the handle 2 of the soft visual laryngoscope.

[0041] When encountering contaminants such as secretions and blood in the oropharyngeal cavity, the contaminants can enter the suction channel from the entrance of the suction channel and eventually be sucked out of the body, thereby preventing the lens of the soft visual laryngoscope from being contaminated by contaminants. When oxygen needs to be supplied to the patient, oxygen can be supplied through the ventilation channel. The gas ejected from the ventilation channel can also prevent the secretions in the oropharyngeal cavity from approaching the lens, thereby better preventing the contaminants from contaminating the lens. When local anesthetics need to be sprayed on the patient's throat, the medication can be administered through the ventilation channel.

[0042] In one embodiment of the soft visual laryngoscope of the present invention, a tongue depressor 4 is further provided on the free end of the mirror body 1. The provision of the tongue depressor 4 is conducive to lifting the tongue root and epiglottis, expanding the field of view in front of the lens, and more effectively preventing the lens from being contaminated.

[0043] Further, the edge of the end of the soft video laryngoscope opposite to the tongue depressor 4 has a rounded corner. The setting of the rounded corner on the soft video laryngoscope is conducive to preventing the soft video laryngoscope from damaging the fragile posterior pharyngeal wall.

[0044] In one embodiment of the soft video laryngoscope of the present invention, the guide channel 3 includes a guide channel body 30 and a guide channel support (not shown in the figure). The curved guide section 301, the insertion guide section 302 and the support guide section 303 can constitute the guide channel body 30.

[0045] The guide channel support is arranged on at least one of the inner wall surface, the outer wall surface and the inner wall of the guide channel body 30, and the guide channel support at least covers the curved guide section 301. The guide channel support can be fixed on the guide channel body 30 by injection molding, adhesion, etc. The guide channel support can be made of metal or plastic. In specific implementation, the guide channel support can be realized by various structures, such as a support ring, a spiral wire or a mesh structure.

[0046] The provision of the guide channel support helps to more effectively prevent the curved guide section 301 from deforming when the mirror body 1 bends.

[0047] The guide channel support may be located only on the curved guide section 301 to reduce costs;

[0048] Alternatively, the guide channel support may be provided on the entire guide channel body 30 to extend the service life of the guide channel 3 .

[0049] Furthermore, the guide channel support has an annular structure to reduce costs.

[0050] The utility model also provides an endotracheal intubation device, which comprises the soft visual laryngoscope of the utility model.

[0051] When the endotracheal intubation device of the utility model is used, the insertion section 12 of the body 1 of the soft visual laryngoscope can be first placed in the oral cavity, and the angle trigger on the handle 2 can be pulled to push the insertion section 12 forward while lifting the tongue and pharyngeal cavity tissue, and the lens assembly at the front end of the insertion section 12 can transmit the image in the oropharyngeal cavity to the display screen in real time. After the insertion section 12 or the tongue depressor 4 exposes the glottis, the guide tube or endotracheal tube is inserted into the glottis through the guide channel 3, and then the soft visual laryngoscope is withdrawn.

[0052] When a tracheal tube is matched with the guide channel 3, intubation is completed at this time.

[0053] When the guide channel 3 is matched with a guide tube, after the soft visual laryngoscope is withdrawn, the endotracheal tube is inserted into the glottis along the guide tube to complete the intubation.
