Description

A kind of visible laryngoscope

Technical field

The utility model relates to medical instruments field more particularly to a kind of visible laryngoscopes.

Background technique

When patient is unconscious, for example, needing to maintain the air flue of patient during general anesthesia.This can be by being inserted in Tracheal catheter in patient airway is completed.The tracheal catheter suitably placed establishes the opening for entering the lung of patient for oxygen Access.One difficult point of trachea cannula is to ensure that tracheal catheter is inserted in the patient airway for lead to lung and leads to trouble without being inserted into In the esophagus of person's stomach.Tool for visually verifying the placement of tracheal catheter is called visible laryngoscope, and tracheal catheter assembly is existed Program in the tracheae of patient is called trachea cannula.

In some clinical settings, the limited neck activity of patient can not allow sufficiently to manipulate head or the neck of patient Portion is with the sight in oral cavity needed for forming trachea cannula to glottis.Visible laryngoscope is the improvement laryngoscope based on common laryngoscope.Visually Laryngoscope is by the laryngoscope blade of general curved in conjunction with setting video camera at the far end.It can be mobile by curved laryngoscope with the smallest neck The oral cavity of piece insertion patient and throat and video camera are connected on image display, which provides for medical staff Correct endotracheal tube places required visual confirmation.

Currently, McCoy type laryngoscope well known in the market, though laryngoscope front end can be adjusted by compression handle, due to this laryngoscope Epiglottis crotch is short, and posting port is intracavitary cannot sufficiently to manifest epiglottis, glottis, and certain difficulty and mistake are caused when to patient cannula It inserts；Though and there is visual camera device in the front end of visible laryngoscope currently on the market, and it is short before glottis can not to provoke gear And small epiglottis, prevent operator from clearly, being accurately inserted into conduit, certain pain is brought to patient.

Summary of the invention

For overcome the deficiencies in the prior art, the utility model provide it is a kind of safe and reliable, can effectively mitigate patient suffering, And the visible laryngoscope for rescuing it in time.

The technical scheme adopted by the utility model to solve the technical problem is as follows:

A kind of visible laryngoscope, including laryngoscope handle, the laryngoscope blade that is connected to laryngoscope handle front end, be connected to laryngoscope handle tail end can Screen curtain；The laryngoscope handle is cylindrical shape, and front end is equipped with threaded handle end cap, and tail end is equipped with the switch of control laryngoscope light source And the loading hatch of battery, it is characterised in that: further include fiber filament, described filametntary one end is connected to visual screen, runs through Along laryngoscope blade laryngoscope handle is stretched out after laryngoscope handle and to laryngoscope blade front end；The part that the fiber filament stretches out laryngoscope handle is equipped with set Pipe, the part beyond casing are mobilizable fiber filament end, and the fiber filament end is equipped with camera；Inside the laryngoscope handle Equipped with for adjusting the control assembly that fiber filament stretches, fiber filament end is swung.

Further, the control assembly includes the plectrum being set on laryngoscope handle, and the fiber filament is corresponding with plectrum Position is equipped with several section card wheels, stirs the card wheel that plectrum makes it block different location up and down, realizes that fiber filament stretches out laryngoscope handle Part is elastic；The control assembly further includes the modulator being arranged on laryngoscope handle, rack gear and is arranged in fiber filament The internal thread in portion, the internal thread are connected to rack gear, and the modulator is equipped with tooth and is engaged with rack, by stirring modulator adjusting tooth Item moves up and down that internal thread is driven to move up and down, final to realize moving up and down for fiber filament end.

After General Anesthesia Undergoing induction, Anesthetist's left hand holds visible laryngoscope described in the utility model, opens laryngoscope blade light Source, closes visual camera head, and conventional merging laryngoscope blade shelters from glottis when encountering short and small epiglottis, can not expose glottis When, visual camera head is opened, the light source of laryngoscope blade is closed, stretches fiber filament forward by adjusting the plectrum on laryngoscope handle, around The epiglottis blocked is crossed, then tilts the fiber filament end with visual camera head by the modulator on laryngoscope handle, by visual Glottis can be seen to screen definition, tracheal catheter is placed in glottis, visible laryngoscope is withdrawn from patient oral cavity by Anesthetist's right hand, after Conventional fixed tracheal catheter, connects Anesthesia machine or ventilator.Generally speaking, the utility model is structurally reasonable, multiple functional, uses behaviour Facilitate, by telescopic fiber filament and movable visual fiber filament end, sufficiently can clearly be manifested by light reflection , there is not error in tracheae, glottis, when intubation, insertion conduit that can be safe and accurate, so that patient is rescued in time, mitigate pain It is bitter.
