DETAILED DESCRIPTION

[0056] 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.

[0057] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0058] 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.

[0059] 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.

[0060] like Figures 1 to 6 As shown, the video laryngoscope provided by the utility model includes a mirror body 1. Generally, the video laryngoscope is composed of a mirror body 1, a handle 2 and a display unit. The handle 2 can be mounted on the end of the mirror body 1, and the display unit can be mounted on the handle 2. The user of the video laryngoscope can operate the video laryngoscope by holding the handle 2. The display unit can be, for example, a display screen. The image captured by the camera at the front end of the video laryngoscope can be observed through the display unit, thereby accurately realizing the operation of visual intubation.

[0061] The mirror body 1 includes a mirror body main body 11 and at least one mirror body component 12, and the mirror body component 12 is rotatably connected to the mirror body main body 11. The mirror body component 12 refers to a component that can form a part of the mirror body 1 of the video laryngoscope, and each mirror body component 12 can have the same or similar structure. The mirror body 1 of the video laryngoscope is constructed by combining the mirror body main body 11 with one or more mirror body components 12. The mirror body component 12 usually has a segmented structure to facilitate assembly or disassembly and ensure the flexibility of the mirror body 1.

[0062] The rotational connection between the mirror body component 12 and the mirror body main body 11 can be achieved by hinge or ball-and-socket connection, etc. The mirror body component 12 is rotationally connected to the mirror body main body 11, and / or multiple mirror body components 12 are connected together by rotational connection, which is conducive to controlling the bending angle of the mirror body 1 of the video laryngoscope according to needs, thereby achieving the purpose of flexible deformation of the video laryngoscope.

[0063] When the mirror body 1 includes a mirror body component 12 , the mirror body component 12 is located at the front end (also called the head end) of the mirror body 1 , and the mirror body component 12 is rotatably connected to the mirror body main body 11 .

[0064] When the mirror body 1 includes two or more mirror body components 12, one of the multiple mirror body components 12 is located at the front end of the mirror body 1, and the multiple mirror body components 12 are rotationally connected in sequence, and a mirror body component 12 adjacent to the handle 2 of the video laryngoscope is rotationally connected to the mirror body main body 11.

[0065] The aforementioned front end refers to the free end of the mirror body 1.

[0066] In addition, a structure for connecting or cooperating with the mirror body component 12 may be provided on the mirror body main body 11. For example, a connecting segment 111 may be provided on the end of the mirror body main body 11, and the components that cooperate or connect with the mirror body component 12 may be provided on the connecting segment 111, so as to facilitate the connection of the mirror body component 12 with the mirror body main body 11 and integrate the structure of the mirror body main body 11. The connecting segment 111 may be provided on the mirror body main body 11 by gluing, snap connection or integral molding. If the connecting segment 111 is connected to the mirror body main body 11 by integral molding, the connecting segment 111 and the mirror body main body 11 may have similar or different cross-sectional profiles. For example, the cross section of the connecting segment 111 has a circular or elliptical outer profile, and the cross section of the mirror body main body 11 has a rectangular outer profile.

[0067] The mirror body component 12 has an extreme rotation position. The above-mentioned extreme rotation position refers to the position of the mirror body component 12 when the mirror body 1 of the video laryngoscope is controlled or pulled to the maximum bending angle.

[0068] When the mirror body component 12 is at the extreme rotation position, there is a first gap between the mirror body component 12 and the mirror body main part 11 or the opposite end face of the adjacent mirror body component 12. The above-mentioned first gap is located between the mirror body component 12 and the mirror body main part 11, or between adjacent mirror body components 12. When the sealing sleeve bends with the mirror body 1 of the video laryngoscope, the folds formed by the sealing sleeve at the inner arc of the bending area of ​​the mirror body 1 can be accommodated in the first gap, thereby effectively avoiding the problem that the folds formed by the sealing sleeve due to the bending hinder the bending of the mirror body 1 of the video laryngoscope.

[0069] The size of the first gap can be set according to actual needs, for example, according to parameters such as the material of the sealing sleeve, the thickness of the sealing sleeve, the length of the sealing sleeve, and the maximum bending angle of the mirror body 1. The first gap can be achieved by providing a limiting structure between the mirror body component 12 and / or the mirror body main body 11, or by providing an avoidance structure on the mirror body component 12 and / or the mirror body main body 11.

[0070] When the mirror body component 12 of the video laryngoscope of the present invention is in the extreme rotation position, the first gap between the mirror body component 12 and the mirror body main body 11 can provide a certain accommodation space for the folds formed by the bending of the sealing sleeve, thereby effectively avoiding the problem of difficulty in bending the mirror body 1 of the video laryngoscope due to the abutment between the bending folds of the sealing sleeve and the outer wall of the video laryngoscope.

[0071] In one embodiment of the video laryngoscope of the present invention, the outer contour of the cross section of the mirror body component 12 and / or the mirror body main body 11 is circular or elliptical. By setting the outer contour of the cross section of the mirror body component 12 and / or the mirror body main body 11 to be circular or elliptical, the sealing sleeve can be conveniently and more tightly matched with the mirror body component 12, thereby achieving a better sealing effect.

[0072] In a specific implementation, the outer contour of the cross section of any part of the entire mirror body component 12 is circular or elliptical; or, the outer contour of the cross section of only the connection between the mirror body component 12 and the mirror body main body 11 or the adjacent mirror body component 12 is circular or elliptical;

[0073] The outer contour of the cross section of any part of the entire mirror body main body 11 is circular or elliptical; or, only the cross section of the connecting segment 111 of the mirror body main body 11 is set to be circular or elliptical.

[0074] In one embodiment of the video laryngoscope of the present utility model, a connection portion 121 for rotational connection with a rotating shaft is provided on the mirror body component 12 and / or the mirror body main body 11. The mirror body component 12 and the mirror body main body 11 are connected to each other through the connection portion 121 of the rotating shaft, or the adjacent mirror body components 12 are connected to each other through the connection portion 121 of the rotating shaft, so as to realize the rotational connection between the mirror body component 12 and the mirror body main body 11 or the rotational connection between adjacent mirror body components 12. The provision of the connection portion 121 is conducive to improving the flexibility of the rotational connection between the mirror body component 12 and the mirror body main body 11 or the rotational connection between adjacent mirror body components 12.

[0075] The connecting portion 121 and the rotating shaft may constitute a hinge structure, thereby realizing the rotational connection between the mirror body component 12 and the mirror body main body 11 or the rotational connection between adjacent mirror body components 12. The connecting portion 121 may be, for example, a protrusion disposed on the end surface or outer wall surface of the mirror body component 12 or the mirror body main body 11. When the connecting portion 121 is disposed on the end surface of the mirror body component 12 or the mirror body main body 11, a first gap may be formed by the protruding connecting portion 121.

[0076] Furthermore, the mirror body component 12 and / or the mirror body main body 11 is also provided with an auxiliary connecting portion 122 for arranging the connecting portion 121. The auxiliary connecting portion 122 may have a plate-like structure or a block-like structure. The connecting portion 121 may be integrally formed with the auxiliary connecting portion 122 or be detachably connected. The auxiliary connecting portion 122 may be adhesively connected or snap-connected or integrally formed with the mirror body component 12 or the mirror body main body 11. The arrangement of the connection part 121 on the mirror body component 12 or the mirror body main body 11 is achieved through the auxiliary connection part 122, and the position of the connection part 121 can be designed more flexibly according to actual usage requirements, so that the connection part 121 can be completely hidden in the channel 123 or the cavity in the mirror body component 12 or the mirror body main body 11, or at least a part of the connection part 121 is located outside the channel 123 or the cavity of the mirror body component 12 or the mirror body main body 11, or the entire connection part 121 is located outside the channel 123 or the cavity of the mirror body component 12 or the mirror body main body 11.

[0077] In practical applications, the connecting parts 121 and / or the auxiliary connecting parts 122 on adjacent mirror body components 12 or the mirror body components 12 and the mirror body main body 11 can be arranged correspondingly to modularly manufacture the mirror body components 12 and reduce production costs.

[0078] In one embodiment of the video laryngoscope of the present invention, a channel 123 is provided in the mirror body component 12 and the mirror body main body 11. A traction through hole portion 124 is provided in the channel 123, and a traction through hole 1240 is provided on the traction through hole portion 124. For example, a traction member such as a pull rope can pass through the traction through hole 1240 on the traction through hole portion 124, thereby realizing the routing of the traction member. The traction through hole portion 124 can have a plate-like structure, a block-like structure, or a ring-like structure.

[0079] One end of the traction member (not shown in the figure) of the video laryngoscope can be fixed on the frontmost mirror body component 12, and the other end passes through the traction through hole 1240 on the traction through hole portion 124, and is connected to the pressure rod or angle trigger on the handle 2. When the pressure rod is pressed or the angle trigger is pulled, the traction member can pull the frontmost mirror body component 12, so that the mirror body 1 of the video laryngoscope is deformed and bent into a required shape.

[0080] In one embodiment of the video laryngoscope of the utility model, a relief portion 125 is provided on the mirror body component 12 and / or the mirror body main body 11, so that when the mirror body component 12 is in the extreme rotation position, there is a second gap between the mirror body component 12 and the opposite end faces of the mirror body main body 11 or between the opposite end faces of adjacent mirror body components 12. The width of the second gap is greater than the width of the first gap. The relief portion 125 may be, for example, a chamfered surface provided on the mirror body component 12 or the mirror body main body 11. The chamfering angles of the chamfered surfaces on the mirror body component 12 and the mirror body main body 11 may be the same or different; the chamfering angles of the chamfered surfaces on different mirror body components 12 may be the same or different.

[0081] When one of the adjacent mirror body components 12 is provided with an escape portion 125, a second gap may be formed between the escape portion 125 and the end surface corresponding to the escape portion 125 of the other mirror body component 12 of the adjacent mirror body component 12. The size of the second gap may be defined by the escape portion 125. The escape portion 125 may form a second gap having a larger width than the first gap, thereby providing a larger accommodation space for the folds formed by the sealing sleeve.

[0082] When the mirror body 1 includes a mirror body component 12, and only one of the mirror body component 12 and the mirror body main body 11 is provided with the avoidance portion 125, the avoidance portion 125 can form a second gap between the end surface corresponding to the mirror body structural member (for example, the mirror body component 12 or the mirror body main body 11) without the avoidance portion 125. The size of the second gap can be defined by the avoidance portion 125. The avoidance portion 125 can form a second gap having a larger width than the first gap, thereby providing a larger accommodation space for the folds formed by the sealing sleeve.

[0083] When the mirror body 1 includes a mirror body component 12, and the mirror body component 12 and the mirror body main body 11 are both provided with an avoidance portion 125, a second gap is formed between the two avoidance portions 125. The size of the second gap can be jointly defined by the two avoidance portions 125. The two avoidance portions 125 can form a second gap having a larger width than the first gap, thereby providing a larger accommodation space for the folds formed by the sealing sleeve.

[0084] When the mirror body 1 includes two or more mirror body components 12, and the adjacent mirror body components 12 are provided with the avoidance portion 125, a second gap is formed between the two avoidance portions 125. The size of the second gap can be jointly defined by the two avoidance portions 125. The two avoidance portions 125 can form a second gap having a larger width than the first gap, thereby providing a larger accommodation space for the folds formed by the sealing sleeve.

[0085] In one embodiment of the video laryngoscope of the present invention, a rotation limiting portion 126 is provided on the mirror body component 12 and / or the mirror body main body 11, and the rotation limiting portion 126 is configured to limit the rotation range of the mirror body component 12. For a mirror body 1 including one mirror body component 12, the rotation limiting portion 126 may be provided on at least one of the mirror body component 12 or the mirror body main body 11. For a mirror body 1 having two or more mirror body components 12, the rotation limiting portion 126 may be provided on at least one of the adjacent mirror body components 12, and may be provided on at least one of the adjacent mirror body components 12 and the mirror body main body 11.

[0086] The rotation limiting portion 126 may be, for example, a protruding structure disposed on the mirror body component 12 or the mirror body main body 11, and the protruding structure may, for example, have a plate-shaped, strip-shaped, or block-shaped structure. When the mirror body component 12 or the mirror body main body 11 rotates until one rotation limiting portion 126 abuts against the end surface of another rotation limiting portion 126 or the mirror body structural member, the rotation of the mirror body component 12 is limited, thereby achieving the effect of limiting the rotation range of the mirror body component 12.

[0087] When the adjacent structural members are both provided with the rotation limiting parts 126 , the two rotation limiting parts 126 can cooperate with each other to realize the rotation limiting function.

[0088] In practical applications, the avoidance portions 125 and / or the rotation limiting portions 126 on adjacent mirror body components 12 or the mirror body components 12 and the mirror body main body 11 can be set correspondingly to modularly manufacture the mirror body components 12 and reduce production costs.

[0089] In one embodiment of the video laryngoscope of the present invention, a straightening member (not shown in the figure) is further provided between the mirror body component 12 and the mirror body main body 11, and / or between adjacent mirror body components 12, and the straightening member is configured to apply a force to the mirror body component 12.

When the straightening member is a coil spring, the two ends of the coil spring may respectively abut against the opposite end faces of the adjacent mirror body component 12, or respectively abut against the opposite end faces of the mirror body component 12 and the mirror body main body 11, thereby achieving the effect of applying a force to the mirror body component 12. Through the force applied to the mirror body component 12 by the straightening member, the mirror body component 12 may form an integral structure similar to a straight rod when it is not controlled or pulled, so that the front end of the video laryngoscope can more conveniently enter the pharyngeal cavity.

[0090] When the mirror body 1 includes one mirror body component 12, the straightening member is arranged between the mirror body component 12 and the mirror body main body 11.

[0134] When the video laryngoscope of the second embodiment is in use, the mirror body component 12 is pulled by the traction member so that the mirror body component 12 is pulled to the extreme rotation position relative to the mirror body main body 11. At this time, a second gap is formed between the avoidance portion 125 of the end mirror body component 12 and the avoidance portion of the mirror body main body 11, and between the avoidance portion 125 of the end mirror body component 12 and the avoidance portion 125 of the head mirror body component 12. The folds formed by the support sleeve and the sealing sleeve at the inner arc of the bending area are accommodated in the second gap, so as to achieve the effect of preventing the folds formed by the bending of the sealing sleeve from hindering the bending of the mirror body 1 of the video laryngoscope.

[0135] like Figure 7 and Figure 8 As shown, the utility model also proposes a visual laryngoscope cover 3.

[0136] The visual laryngoscope cover 3 includes a hard cover member 31, a deformable cover member 32 and a cover tongue depressor 33. The hardness of the hard cover member 31 is greater than that of the deformable cover member 32. The hard cover member 31 can be made of plastic or metal, and the hardness of the hard cover member 31 enables it to be stably positioned on the mirror body member 12 and / or the mirror body main body 11. The deformable cover member 32 can be made of a plastic material with a certain elasticity, or a member with flexible deformation ability (such as a bellows), so that the deformable mirror body member 12 can be flexibly bent as the mirror body 1 is deformed. The deformable cover member 32 can correspond to the connection between the mirror body members 12 or the connection between the mirror body member 12 and the mirror body main body 11, so that the visual laryngoscope cover 3 can flexibly adapt to the deformation of the mirror body 1. The length of the hard cover member 31 and the length of the deformable cover member 32 can be flexibly set according to the needs, and the utility model is not further limited here.

[0137] The hard lens cover component 31 and the deformable lens cover component 32 are arranged at intervals, and the hard lens cover component 31 matches with the lens body component 12 and / or the lens body main body 11. The hard lens cover component 31 matches with the lens body component 12 and / or the lens body main body 11 by means of snap connection and / or shape adaptation.

[0138] The hard lens cover component 31 includes a head end lens cover component 311 and a non-head end lens cover component. The head end lens cover component 311 cooperates with the mirror body component 12 at one end away from the handle 2 of the video laryngoscope (which can be called the frontmost mirror body component 12 or the head end mirror body component), and a transparent baffle is provided on the head end lens cover component 311. The transparent baffle fits with the free end surface of the frontmost mirror body component 12 to avoid the problem of unclear image acquisition caused by reflection of the transparent baffle.

[0139] The scope cover tongue depressor 33 is arranged on the head end scope cover member 311. The scope cover tongue depressor 33 can be connected with the head end scope cover member 311 by gluing or integral molding. Generally, the visual laryngoscope scope cover 3 with the scope cover tongue depressor 33 can be used in conjunction with a visual laryngoscope without a scope body tongue depressor member 13. Of course, for a visual laryngoscope with a scope body tongue depressor member 13, the scope cover tongue depressor 33 can be sleeved outside the scope body tongue depressor member 13, so as to realize the matching use of the visual laryngoscope scope cover 3 with the scope cover tongue depressor 33 and the visual laryngoscope with the scope body tongue depressor member 13.

[0140] Generally, a hard mirror cover component 31 may be positioned on each mirror body component 12. For a video laryngoscope having a longer mirror body main body 11 (e.g., the mirror body 1 of the video laryngoscope has only one mirror body component 12), the hard mirror cover component 31 and the deformable mirror cover component 32 of the rear section (except the head end mirror cover component 311) of the video laryngoscope cover 3 are both positioned on the mirror body main body 11.

[0141] The video laryngoscope cover 3 of the utility model can be mounted on the body 1 of the video laryngoscope, effectively isolating the body 1 from the external environment. When in use, only the video laryngoscope cover 3 needs to be replaced without cleaning and disinfecting the body 1, thereby improving the convenience of using the video laryngoscope. Moreover, the video laryngoscope cover 3 formed by the hard cover component 31 and the deformable cover component 32 is convenient to use and can be flexibly and easily mounted on the body 1 of the video laryngoscope.

[0142] In one embodiment of the video laryngoscope cover of the present utility model, the non-head end cover component includes a terminal cover component 312, and the terminal cover component 312 cooperates with the mirror body main body 11 and / or the handle 2 of the video laryngoscope. The head end cover component 311 and the terminal cover component 312 are respectively located at the head and tail ends of the video laryngoscope cover 3. The terminal cover component 312 can be positioned only on the mirror body main body 11, or the terminal cover component 312 can cover the section of the mirror body main body 11 adjacent to the handle 2 of the video laryngoscope and the handle 2 of the video laryngoscope.

[0143] A fixing part is provided on the head end mirror cover component 311 and / or the terminal mirror cover component 312. The fixing part may be, for example, a buckle or a thread or a shrinking structure with a shrinking inner diameter. The head end mirror cover component 311 and / or the terminal mirror cover component 312 may be fixed to the video laryngoscope through the fixing part, so as to prevent the video laryngoscope cover 3 from falling off from the video laryngoscope uncontrollably, thereby improving the stability and safety of the use of the video laryngoscope cover 3.

[0144] In one embodiment of the video laryngoscope cover of the utility model, the fixing portion is a thread or a buckle.

[0145] In one embodiment of the video laryngoscope cover of the present utility model, the hard cover component 31 is made of hard plastic material or metal material.

[0146] In one embodiment of the video laryngoscope cover of the present utility model, the deformable cover component 32 is made of soft plastic material, silicone material or rubber material, or the deformable cover component 32 is a bellows.

[0147] In one embodiment of the video laryngoscope cover of the utility model, at least part of the hard cover member 31 is provided with cover wings, which extend outward from the outer surface of the hard cover member 31. The cover wings can be formed on the hard cover member 31 by integral molding, gluing, snap connection and gluing combination, snap connection and threaded connection. The cover wings can have a plate-like structure.

[0148] When performing endotracheal tube intubation, the side wings of the scope can support and form a channel for inserting the endotracheal tube in the oropharyngeal cavity, thereby providing a more convenient operating space for endotracheal tube intubation.

[0149] Generally, the video laryngoscope cover 3 with cover wings can be used in conjunction with a video laryngoscope without main wings 112 and without body component wings 14. Of course, for a video laryngoscope with main wings 112 and / or body component wings 14, the cover wings can be sleeved outside the main wings 112 and / or body component wings, thereby achieving the matching use of the video laryngoscope cover 3 with cover wings and the video laryngoscope with main wings 112 and / or body component wings 14.

[0150] In one embodiment of the video laryngoscope cover of the utility model, a rotation-limiting structure (not shown in the figure) is provided on the outer surface of the mirror body component 12 and / or the mirror body main body 11. The rotation-limiting structure cooperates with the hard mirror cover component 31 to prevent the hard mirror cover component 31 from rotating relative to the mirror body component 12 and / or the mirror body main body 11.

[0151] The rotation limiting structure may be, for example, a protrusion (for example, a columnar protrusion, a hemispherical protrusion, a pointed protrusion or a conical protrusion, etc.), a groove, or a structure having a polygonal (triangular, quadrilateral or hexagonal, etc.) outer contour in cross section on the outer surface of the mirror body component 12 and / or the mirror body main body 11.

[0152] The hard mirror cover component 31 may be provided with a structure that cooperates with the rotation limiting structure, or the hard mirror cover component 31 may have an inner contour that matches the rotation limiting structure, so that the rotation limiting structure can cooperate with the hard mirror cover component 31 to ensure the stability and reliability of the positioning of the video laryngoscope cover 3 on the video laryngoscope.

[0153] In addition, during specific implementation, the side wings of the mirror body component can be set on the rotation limiting structure.

[0154] Furthermore, the rotation limiting structure is at least one of a protrusion, a groove or a structure with a polygonal outer contour in cross section. The structure with a polygonal outer contour in cross section may be, for example, a polygonal ring that can be sleeved on the outer surface of the mirror body component 12 and / or the mirror body main body 11.

[0155] Furthermore, the structure with a polygonal outer contour in cross section is connected to the mirror body component 12 and / or the mirror body main body 11. The above connection can be achieved by integral molding, snap connection, or gluing.

[0156] The utility model also provides a visual laryngoscope assembly, which comprises the visual laryngoscope of the present application.
