Description
Technical field
The present invention relates to technical field of medical instruments, more particularly to a kind of trachea cannula wireless video laryngoscope.
Background technology
Video laryngoscope is that a kind of conventional visual air flue of hospital checks equipment, and video laryngoscope is used for trachea cannula not only
Difficult airway intubation is effectively solved, and is also had great advantage to general patient：Reduce the technical difficulty of trachea cannula, hence it is evident that subtract
The emergency reaction of light trachea cannula, reduces the damage of trachea cannula.
However, generally there is following defect in existing video laryngoscope：Existing video laryngoscope is generally all to carry display,
The video laryngoscope of this kind of structure type not only increases laryngoscope weight, also increases the space-consuming of mirror handle, such as runs into fat, short
Then laryngoscope is difficult to insert oral cavity by neck, mental sternal adhesion patient；Moreover, also causing use cost increase, penetration and promotion is not easy to.
In addition, the eyeglass front end of existing video laryngoscope and guiding groove are all fixed, it is difficult to inserted suitable for tracheae
Various situations in pipe, for example, Airtraq video laryngoscopes, because profile is in " J " type, the patient's glottis for meeting high larynx is difficult cruelly
Dew is, it is necessary to retreat eyeglass and bigger upper lifting force, the compressing regulation of neck outside or joint bougie intubation；Pentax-AWS laryngoscopes are inserted
Glottis exposure is not good during epiglottic vallecula makes eyeglass be placed in behind epiglottis, it is necessary to adjust laryngoscope；Throat anatomical variation person, video laryngoscope
Guiding groove is difficult to be directed at glottis, and the exposure of glottis, intubation can all become intractable.Video laryngoscope with guiding groove is also not suitable for intranasal
Intubation or two-chamber cannula, and without guiding groove Glidescope or UE video laryngoscopes meet some difficult airways when then glottis it is easy
Exposure is difficult intubation.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of wide tracheae of simple in construction, easy to use, applicability and inserted
Effective wireless video laryngoscope.
To solve the technical scheme that above-mentioned technical problem is used：A kind of trachea cannula wireless video laryngoscope, including larynx

Device and the WIFI signal transmitter being respectively connected with microcontroller, video-frequency signal converter, the video-frequency signal converter with
Camera is connected by wire, the laryngeal mirror lens be sleeved on metal hose it is outer and with mirror handle phase clamping, the laryngeal mirror lens
Front end is hinged with hyoplastron part, the lever regulated mechanism that side wall is rotated provided with driving hyoplastron part outside the laryngeal mirror lens,
The laryngeal mirror lens opposite side wall is formed with the trachea cannula guiding groove that can be closed or deploy.
Further, the laryngeal mirror lens side slidably connects L-shaped side plate, when the L-shaped side plate outwards slides, institute
State the gap between L-shaped side plate and laryngeal mirror lens and constitute trachea cannula guiding groove, the land width of the laryngeal mirror lens is more than larynx
The concave surface width of mirror eyeglass, when the L-shaped side plate inwardly slides, the L-shaped side plate fastens to form one with laryngeal mirror lens, institute
The land width for stating laryngeal mirror lens is less than the concave surface width of laryngeal mirror lens.
Further, the laryngeal mirror lens two ends are formed with chute, and the L-shaped side plate two ends have been correspondingly formed embedded chute
Interior slide rail, is embedded with the chute and supports the spring of slide rail so that L-shaped side plate outwards slides relative to laryngeal mirror lens, in institute
Laryngeal mirror lens are stated provided with the strip projection parallel with laryngeal mirror lens, the strip projection front end has slope, the L-shaped side plate
Provided with the recess that can be fastened on strip projection, when the L-shaped side plate inwardly slides, it is convex that the recess correspondence is fastened on strip
So that L-shaped side plate fastens to form one with laryngeal mirror lens on block.
Further, the lever regulated mechanism includes connecting rod, handle, bearing pin, rotating shaft and the torsion spring being sleeved in rotating shaft,
The side of hyoplastron part one is hinged laryngeal mirror lens front end, and another side of hyoplastron part forms fan-shaped lack with laryngeal mirror lens front end
Mouthful, described connecting rod one end is hinged with another side of hyoplastron part, and the connecting rod other end is hinged with handle one end, the rotating shaft
Laryngeal mirror lens rear end is fixed on, the middle handle is hinged with rotating shaft, the torsion spring elasticity in the rotating shaft is supported on handle
So that sector notch is maintained at an initial angle, the bearing pin is fixed on laryngeal mirror lens rear end, on the handle be provided with
The pin-and-hole of bearing pin adaptation, limits it with fixed handle by the mating connection of the bearing pin and pin-and-hole and rotates.
Further, the regulation angle of the openings of sizes of the sector notch is 30 ~ 60 degree.
Further, the mirror handle top detachable connection has Mobile phone holders, leads between the mirror handle and Mobile phone holders
Cross universal joint detachable connection.
Further, the universal joint includes ball rod and bulb cap, and the bulb cap is fixed on mirror handle top, described
Ball rod one end has the bulb being adapted with bulb cap, and the ball rod other end is connected with Mobile phone holders.
Further, there is the charge power supply that electric power is provided to light source, provided with control on the mirror handle in the mirror handle
