It should be noted that: unless specifically stated otherwise, the relative arrangement of the components and steps, the numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present invention.

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.

Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.

In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.

As shown in fig. 1 to 4, the laryngoscope sheath provided by the utility model comprises a handle 1 and a sheath main body 2.

The handle 1 is provided with a first tubular core passage (not shown in the figures). When the laryngoscope sheath and the tubular core are combined together, the tubular core can enter the handle 1 from a first tubular core channel on the handle 1 and pass through the handle 1 to enter the sheath body 2. In specific implementation, the tube core can be positioned on the handle 1 by means of snap fixing, embedding and the like.

The handle 1 is fixedly connected with the mirror sleeve main body 2. The fixed connection between the handle 1 and the mirror sleeve main body 2 can be realized by welding or screw thread connection and the like. In order to ensure the stability of the connection between the handle 1 and the mirror sleeve body 2, the handle 1 and the mirror sleeve body 2 can be fixedly connected together by adopting an undetachable connection mode.

The mirror housing main body 2 includes a support member 21 and a cover film (not shown in the drawings). The coating film covers the outside of the support assembly 21. The coating film may function as an auxiliary support member 21 as well as a sealing support member 21. In specific implementation, the covering film is wrapped outside the supporting component 21. The coating film may be made of, for example, a woven fabric or a resin.

The support assembly 21 includes a traction member (not shown) and a plurality of support members 211. One side of the support member 21 is connected to the handle 1. A second die channel 2111 is provided in the support 211, the first and second die channels 2111 communicating such that a die may enter the second die channel 2111 from the first die channel. The second die passage 2111 provided in each support 211 may constitute an integral passage for die passage. In specific implementation, the shape and size of each support 211 can be flexibly set according to actual requirements.

One end of the adjacent sidewalls of each support 211 is connected. The joint of the adjacent side walls of the adjacent supporting pieces 211 is located at the end of each side wall, so that the adjacent supporting pieces 211 can support each other at the end of the side walls when the relative movement occurs, and the effect of stabilizing the mirror sleeve main body 2 in the bending deformation process is achieved. Moreover, the connection point of the adjacent supporting members 211 at the end of the adjacent side wall is also beneficial to increase the moving range of the supporting members 211 and reduce the interference between the adjacent supporting members 211. When the relative position of the adjacent supporting members 211 changes, the adjacent supporting members 211 rotate relative to each other with the joint between the supporting members 211 as a rotation axis. In specific implementation, the connection between the adjacent supporting members 211 can be realized through connecting shafts, flexible connecting sheets and other connecting modes.

In addition, a certain distance may be provided between the connection ends of the adjacent side walls of the adjacent supports 211 to increase the movable range of the supports 211, so that the bending deformation of the mirror sleeve body 2 is more flexible.

A transparent baffle 2112 is arranged on the supporting piece 211 at one end of the mirror sleeve main body 2 far away from the handle 1. The tube core can capture an image outside the mirror housing body 2 through the transparent baffle 2112.

The traction member is used to control the position of the support member 211 to change the bending angle of the mirror sleeve body 2. The pulling member may be, for example, a pulling rope, and a force may be applied to the support 211 by the pulling member to pull the support 211, so that the position of the support 211 is changed. Alternatively, the pulling member may be, for example, a pull rod connected to the support 211, and the pull rod is driven by an electric or manual driving mechanism, so that the position of the support 211 is changed.

In specific implementation, one end of the traction member may be fixedly connected to the supporting member 211 provided with the transparent baffle 2112 in the supporting assembly 21, and the other end of the traction member may penetrate through the supporting member 211 and the handle 1 and then be exposed outside the handle 1, so that an operator may directly apply force to the traction member.

The laryngoscope cover of the utility model can have two states of a relaxed state and a stressed state, and the specific description is as follows:

in the relaxed state, the supporting member 211 is not acted by the pulling member, and the position of the supporting member 211 is not changed by the external force. At this time, the sidewalls to which the supports 211 are connected may maintain a certain interval and have no strong interaction.

Under the stress state, the supporting member 211 provided with the transparent baffle 2112 is acted by a traction member, the position of the supporting member 211 provided with the transparent baffle 2112 is changed relative to the adjacent supporting member 211, the adjacent side walls of each supporting member 211 are jointed or mutual acting force exists between the adjacent side walls of each supporting member 211, so that the supporting member 211 moves under the supporting action of the adjacent supporting member 211. Adjacent side walls of each support 211 are abutted or there is a mutual force between adjacent side walls of each support 211, so that the supports 211 move under the supporting action of the adjacent supports 211.

When the laryngoscope is in a stressed state, the bending angle of the laryngoscope sleeve main body 2 can be flexibly adjusted according to the change of the acting force of the traction piece. The curved body 2 of the sleeve provides a greater lifting force due to the mutual support of the supports 211, so that a laryngoscope fitted with a laryngoscope sleeve will lift the epiglottis directly to expose the glottis.

The utility model discloses a laryngoscope mirror cover is when using, earlier with the tube core through first tube core passageway and second tube core passageway 2111 assembly in the laryngoscope mirror cover, inserts patient's oral cavity with mirror cover main part 2 again, pulls the piece according to bending angle demand control, makes mirror cover main part 2 take place the bending of different degrees. After the camera on the tube core sees the epiglottis through the transparent baffle 2112, the scope housing body 2 is flexed by the action of the traction member on the scope housing body 2, thereby raising the epiglottis to expose the glottis. During glottic exposure, the laryngoscope sleeve may also be lifted appropriately to assist in exposing the glottis and to increase the oropharyngeal space, thereby facilitating insertion of the endotracheal tube.

The utility model discloses a laryngoscope mirror cover accessible pulls the bending angle of a control mirror cover main part 2, and the bending deformation of mirror cover can drive tube core bending deformation. The connection between the ends of the adjacent side walls of the support members 211 of the support assembly of the sheath enables the support members 211 to support each other when the sheath body 2 is deformed, thereby providing a greater uplifting force, enabling the laryngoscope to be directly uplifted at the epiglottis to expose the glottis, simplifying the steps of intubation and facilitating intubation efficiency. Moreover, the tube core can be effectively isolated from the external environment by the laryngoscope cover, and the laryngoscope only needs to be replaced without cleaning and disinfecting the tube core when in use, thereby improving the use convenience of the laryngoscope.

In one embodiment of the laryngoscope cover of the present invention, a tongue depressor 22 is further disposed on the cover main body 2. The tongue depressor 22 may be fixed to the support member 211 provided with the transparent baffle 2112 by welding, integral molding, or the like. When the laryngoscope cover provided with the tongue depressor 22 is used, after the epiglottis is seen by the camera on the tube core, the tongue depressor 22 of the laryngoscope cover extends into the vallecula of the epiglottis, and the epiglottis is lifted to expose the glottis. Moreover, the laryngoscope cover provided with the tongue depressor 22 can increase the visual field at the front end of the laryngoscope and identify the structure of the oropharyngeal cavity more easily in the process of being inserted into the oropharyngeal cavity.

In one embodiment of the laryngoscope cover of the present invention, the pulling element is a pull cord connected to each support element 211. The connection between the pull cord and each support member 211 may be a fixed connection or a slip fit connection. For example, the pulling rope and the supporting member 211 provided with the transparent baffle 2112 can be connected together by welding or by means of a snap fit of a protrusion and a groove. For another example, the connection between the pull rope and the other supporting member 211 without the transparent barrier 2112 can be realized by providing a pull rope through hole on the supporting member 211, and allowing the pull rope to pass through the pull rope through hole; or, the stay cord is arranged on the support member 211, and the stay cord passes through the stay cord ring; alternatively, the stay rope is passed through a stay rope tube provided on the support member 211. In particular implementations, the drawstring loop or drawstring tube may be disposed on an outer surface of the support member 211, or on an inner wall surface of the second tube core channel 2111 or the line channel 2115 within the support member 211.

The pull cord is movable within the cord passage 2113 of the support member 211 such that the support member 211 is moved by the pull cord when the pull cord is moved to a position where the force applied to the support member 211 is sufficiently large (e.g., the pull cord abuts a wall surface of the cord passage 2113 of the support member 211).

In particular implementations, the pull-cord channel 2113 may be a pull-cord via disposed in a wall of the support 211; alternatively, the pull-cord passage 2113 may be a pull-cord tube attached to the inner wall of the second-wick passage 2111 or the line passage 2115 of the support member 211 by welding, bonding, or the like, through which the pull cord may pass; still alternatively, the pull rope passage 2113 may be a pull rope tube attached to the outer wall surface of the support member 211 by welding, bonding, or the like, through which the pull rope may pass.

Further, the support assembly further comprises a drive member 212, the drive member 212 being mounted on the handle 1. The drive member 212 is connected to one end of the pull cord. The driving member 212 can more flexibly and reliably drive the pulling rope, so that the supporting member 211 is pulled by the pulling rope under different stress conditions.

In one embodiment, the driving member 212 is an angle trigger, knob or lever. The angle trigger is connected with the handle 1 in a rotating manner, and the angle trigger can be fixedly connected with one end of the pull rope, so that the pull rope can be driven to pull the supporting piece 211 through the rotation angle trigger. The knob is screwed to the handle 1, and the length of the pulling rope is changed by screwing in and out the knob on the handle 1, thereby pulling the support 211. The pressure bar can be rotatably connected with the handle 1 and can be fixedly connected with one end of the pull rope, so that the pull rope can be driven to pull the supporting piece 211 by applying force to the pressure bar.

Further, the support assembly 21 comprises at least two pulling members, each pulling member being fixedly connected to a different connection location on the support member 211 provided with the transparent barrier 2112. The arrangement of the plurality of traction pieces can more effectively apply force to the supporting piece 211 provided with the transparent baffle 2112, so that the problem that the mirror sleeve main body 2 deviates in the bending deformation process is avoided, and the controllability of the mirror sleeve main body 2 is improved. In a specific implementation, the positions where the plurality of pulling members are connected to the supporting member 211 provided with the transparent barrier 2112 are all located on the same surface of the supporting member 211 provided with the transparent barrier 2112, and the positions where the pulling members are connected to the supporting member 211 provided with the transparent barrier 2112 may be located on the upper edge of the surface of the supporting member 211 provided with the transparent barrier 2112 opposite to the adjacent supporting member 211.

In addition, multiple traction elements may cooperate with the same drive element 212.

Further, a plurality of branch lines fixedly connected with different connection positions on the supporting member 211 provided with the transparent barrier 2112 are provided on the end of the single traction member. The mode that a single traction piece is connected with a plurality of connecting positions on the supporting piece 211 provided with the transparent baffle 2112 can more effectively apply force to the supporting piece 211 provided with the transparent baffle 2112, so that the problem that the mirror sleeve main body 2 deviates in the bending deformation process is avoided, and the controllability of the mirror sleeve main body 2 is improved. In specific implementation, the positions of the plurality of branch lines connected with the traction member on the support member 211 provided with the transparent barrier 2112 are all located on the same surface of the support member 211 provided with the transparent barrier 2112, and the connection positions can be uniformly distributed on the surface of the support member 211 provided with the transparent barrier 2112, and the connection positions of the traction member and the support member 211 provided with the transparent barrier 2112 can be located on the upper edge of the surface of the support member 211 provided with the transparent barrier 2112 opposite to the adjacent support member 211.

In an embodiment of the laryngoscope cover of the utility model, the laryngoscope cover further comprises a suction tube 3. One end opening of the suction tube 3 is positioned on the end surface of the support member 211 provided with the transparent baffle 2112, and the other end opening of the suction tube 3 is positioned on the handle 1. The pollutants such as secretion and blood in the oropharynx cavity can enter the suction tube 3 from the inlet of the suction tube 3 on the end face of the supporting piece 211 provided with the transparent baffle 2112 and leave the laryngoscope cover from the outlet on the handle 1.

When encountering pollutants such as secretion, blood and the like in the oropharyngeal cavity, the laryngoscope sleeve provided with the suction tube 3 enables the pollutants to enter the suction tube 3 from the inlet of the suction tube 3 by controlling a suction unit (such as an air pump) connected with the outlet of the suction tube 3 and finally to be sucked out of the body, thereby achieving the purpose of preventing the transparent baffle 2112 of the laryngoscope sleeve from being polluted by the pollutants.

In an embodiment of the laryngoscope cover of the present invention, the laryngoscope cover further comprises a ventilation tube 4. One end opening of the vent pipe 4 is positioned on the end surface of the support member 211 provided with the transparent baffle 2112, and the other end opening of the vent pipe 4 is positioned on the handle 1. Oxygen or local anaesthetic may enter the laryngoscope sleeve from an inlet on the handle 1 of the ventilation tube 4 and enter the pharyngeal cavity from an outlet on the support 211 provided with a transparent barrier 2112.

A laryngoscope provided with a ventilation tube 4 can provide oxygen through the ventilation tube 4 when it is desired to provide oxygen to a patient. The gas ejected from the ventilation tube 4 can also prevent secretions in the oropharyngeal cavity from approaching the transparent baffle 2112, so that the effect of better preventing pollutants from polluting the transparent baffle 2112 is achieved. When it is desired to spray a local anesthetic to the throat of a patient, the drug can be administered through the ventilation tube 4.

The technical personnel in the field can arrange the suction tube 3, or arrange the breather pipe 4, or arrange the suction tube 3 and the breather pipe 4 simultaneously on the laryngoscope lens sleeve according to the actual demand. When the suction tube 3 and the vent tube 4 are arranged on the laryngoscope mirror sleeve at the same time, a certain distance can be arranged between the outlet and the inlet of the suction tube 3 and the vent tube 4, so that the functions of the laryngoscope mirror sleeve are not mutually influenced when the operations of suction, air supply and drug administration are carried out.

Further, a partition plate 2114 is provided in the support 211. A divider plate 2114 divides the interior cavity of the support 211 into a second die passage 2111 and a line passage 2115. The suction tube 3 and/or the vent tube 4 are disposed within the line passage 2115. The arrangement that the inner cavity of the support member 211 is divided by the partition plate 2114 to form two channels is beneficial to avoiding the interference of the tube core entering the lens sleeve main body 2 with the suction tube 3 and the vent tube 4. The size of the second die channel 2111 and the pipeline channel 2115 can be flexibly set according to actual requirements.

In one embodiment of the laryngoscope cover of the present invention, the supporting member 211 is provided with a wing 213, and the wing 213 extends from the outer surface of the supporting member 211 towards the direction away from the main body 2 of the cover. The side flaps 213 may have a plate-like structure. When performing an endotracheal intubation procedure, the wings 213 may support the formation of a channel for endotracheal intubation within the oropharyngeal cavity, thereby providing more convenient operating space for endotracheal intubation.

In practical applications, the extending direction of the side wing 213 can be parallel to the central axis of the lens sleeve main body 2 in the relaxed state.

In an embodiment of the laryngoscope sheath of the present invention, the supporting component 21 further comprises a guiding channel (not shown in the figure), the guiding channel is disposed on the outer wall surface of the sheath main body 2, and the guiding channel extends along the length direction of the sheath main body 2.

The guide passage may be a groove-like structure directly formed on the outer wall surface of the supporter 211. Alternatively, the guide passage may be a guide tube (having a certain elasticity) attached to an outer wall surface of the support 211. Alternatively, the guide channel may be a guide tube fixed in a groove-like structure on the outer wall surface of the support 211.

The connecting surface 2116 of the supporting piece 211 can combine a plurality of supporting pieces 211 into an integral supporting component 21, and the arrangement of the matching surface 2117 can play a role of mutual supporting of the adjacent supporting pieces 211, so that the endoscope sleeve main body 2 can have larger uplifting force, and the epiglottis can be directly uplifted by the laryngoscope sleeve at the epiglottis valley to expose the glottis, thereby simplifying the steps of intubation operation and being beneficial to improving the intubation efficiency.

The coupling face 2116 of the support members 211 refers to a face on which surfaces may be provided on the support members 211 that couple the support members 211 together. The mating surface 2117 of the support member 211 refers to the surface of the support assembly 21 that abuts or supports each other when acted upon by the puller. The positions of the connection surface 2116 and the mating surface 2117 are different depending on the shape configuration of the support member 211. For example, when the support member 211 is in a truncated pyramid shape, the connection surface 2116 may be located on the bottom surface of the support member 211, the engagement surface 2117 may be located on the side surface of the support member 211, and the engagement surfaces 2117 of adjacent support members 211 may be completely attached together. For another example, when the supporting members 211 are rectangular parallelepiped, the connection surface 2116 may be located on the bottom surface of the supporting member 211, the matching surface 2117 may be located on the side surface of the supporting member 211, and the matching surfaces 2117 of the adjacent supporting members 211 support each other in a line contact or a surface contact manner.

In one embodiment, the supporting members 211 may have a regular shape, but the shape or size of the supporting members 211 is not necessarily the same. Different supports 211 may be provided having different shapes and/or sizes when required for particular uses.

Further, in order to enhance the mutual supporting effect between the supporting members 211 and increase the lifting force of the mirror sleeve body 2, the angle formed between the connecting surface 2116 and the mating surface 2117 is less than or equal to 90 °. Thus, by reasonably setting the distance between the adjacent supporting pieces 211, after the traction piece is applied with force, the matching surfaces 2117 of the adjacent supporting pieces 211 can be completely attached together, so that a better mutual supporting effect is realized, and a larger force is provided when the laryngoscope sleeve is lifted.

Further, the support member 21 further includes a connecting piece (not shown), and both ends of the connecting piece are respectively connected to the connecting surfaces 2116 of the adjacent support members 211. In this embodiment, the edges of the connection surface 2116 of the adjacent supporting member 211 are respectively connected to the two ends of the connection piece, so that a certain distance is formed between the edges of the connection surface 2116 of the adjacent supporting member 211, thereby increasing the moving space of the supporting member 211 and facilitating the realization of more flexible control of the bending angle of the mirror sleeve main body 2.

In specific implementation, the connecting sheet may be made of, for example, silicone, PVC, or rubber, and the connection between the connecting sheet and the supporting member 211 may be achieved by plastic welding or gluing.

Further, the support assembly 21 further comprises a hinge (not shown) connecting the edges of the connection faces 2116 of adjacent support members 211. In this embodiment, the edges of the connection surface 2116 of the adjacent supporting members 211 are respectively connected to two ends of the hinge member, so that the adjacent supporting members 211 can rotate around the hinge member as a shaft, thereby increasing the moving space of the supporting members 211 and facilitating the realization of more flexible control of the bending angle of the mirror sleeve main body 2.

In particular embodiments, the hinged member may be, for example, a rotating shaft or a hinge.

In one embodiment of the laryngoscope sleeve of the present invention, the support assembly 21 further comprises a support strip 2118. The connection surface 2116 of the supporting member 211 is attached to the supporting bar 2118, and the connection surface 2116 of the supporting member 211 is connected to the supporting bar 2118. The connecting surface 2116 of each supporting member 211 is connected with the surface of the supporting bar 2118, the supporting bar 2118 can combine a plurality of supporting members 211 into a whole, and the lifting force of the mirror sleeve main body 2 can be further enhanced by the supporting function of the supporting bar 2118. The support strip 2118 may be, for example, a strip of PVC or adhesive tape having some flexibility.

In one embodiment, the supporting bars 2118 can extend to all the supporting members 211, so that the whole mirror casing main body 2 can be formed as a whole to provide a larger supporting force.

Further, the support 211 has a frame-like structure. The support 211 with the frame structure has light weight, and can effectively reduce the weight of the laryngoscope cover. Moreover, in the process of manufacturing the laryngoscope mirror sleeve, the frame type structure can facilitate the pipe and the wire to pass through the supporting piece 211, and different accessories can be conveniently arranged on each part of the frame on the supporting piece 211 of the frame type structure, thereby realizing the personalized customization of the laryngoscope mirror sleeve.

Further, the cross section of the support 211 along the width extension direction of the mirror sleeve body 2 is square, rectangular, semicircular, oval or trapezoidal. The supporting pieces 211 with different shapes can meet the use requirements of different laryngoscope covers.

Further, the supporting member 211 has a trapezoidal cross section along the longitudinal extension direction of the mirror sleeve main body 2, the connecting surface 2116 is located on the lower bottom surface of the supporting member 211, and the matching surface 2117 is located on the side waist surface of the supporting member 211. When the mirror sleeve main body 2 of the supporting member 211 with such a structure is bent and deformed, the matching surfaces 2117 of the adjacent supporting members 211 can be completely attached together, thereby achieving a more effective supporting effect and providing a larger lifting force to the mirror sleeve main body 2.

Further, in order to allow the pulling member to pull the supporting member 211 more flexibly, the connection point of the pulling member and the supporting member 211 is the farthest point from the connection point 2116 on the supporting member 211. For example, when the support member 211 has a regular frustum shape, the connection surface 2116 may be located on a lower bottom surface of the support member 211, the mating surface 2117 may be located on a side surface of the support member 211, and the traction member is connected to an upper bottom surface of the support member 211.
