Description
Technical field
Auxiliary device when this utility model relates to the anesthesia tracheal intubation, especially a kind of electric video laryngoscope.
Background technology
At present, conventional in anesthesia surgery what use is the cassette laryngoscope, is 03264840,5 Chinese utility model patent as the patent No., and number of patent application is 200520041786,8 Chinese utility model application.It is by the deck of double as operating grip and battery case and push down tongue with fork-like farm tool used in ancient China and provoke the card that epiglottis exposes glottis and form.Card is anterior with lampet, throws light on during as intubate.This kind laryngoscope is simple for structure, and operation is convenient, is easy to sterilization.Therefore, in the endotracheal intubation anesthesia surgery of routine, be used widely.But cassette laryngoscope illumination is insufficient, and angle of visibility is little, and intubate gropingly by rule of thumb under dim light is operated careless slightlyly, will cause damage to throat and air flue.Particularly under emergency situation,, cardiac arrest critically ill, throat and air flue damage as the patient, must be rapidly intubate correctly.The intubate operation depends on Anesthetist's operant skill too much, and this is that we are undesirable.
The situation of visual laryngoscope energy clear demonstration throat and gas port, the rapid positive stop of guide cannula is guaranteed patient not to be caused new injury in the intubate process.For example at Chinese technology trade disclosed on the net " double-colored cold light source video laryngoscope ", a kind of visual laryngoscope is disclosed, comprise chassis, be installed in the video laryngoscope handle on the chassis, handle connects the arc oropharyngeal airway and presses tongue cover board component, battery is installed in the described handle, described arc oropharyngeal airway and pressure tongue cover board component front end are installed illuminating lamp and photographic head, at chassis the display that is used for display image are installed, and described photographic head is connected with display by data wire.The defective that this scheme exists: display and handle are installed in the diverse location of chassis, and the doctor needs just can carry out correct operation facing to display when operation, because the position of intubate has specificity, make troubles to doctor's operation.
The patent No. is 200820057809,8 Chinese utility model patent for another example, the visual anesthetic laryngopharyngoscope of a kind of dismountable is disclosed, buckle-type connects between laryngoscope and the handle, both electrical connections are connected by conductive contact after the clamping, the laryngoscope front end has illuminating lamp and imageing sensor photographic head, handle rear end has LCDs, flexibly connects between LCDs and the handle, can rotate and pitching each other.The defective of its existence is: 1, battery is installed in the handle, cause decreased food long, intubate patient lies in a comatose condition, its head can not be steeved backward, therefore, patient's throat and the distance between the anterior part of chest are shorter, especially the bigger aeg of some adiposis patients or chest, because the spatula of laryngoscope is circular arc, if decreased food is long, when inserting patient's mouth, the anterior part of chest and the inconsistent situation of handle end that occur patient easily, therefore the length of handle need be controlled in the particular range, if handle surpasses particular range, then patient's shirtfront can prop up the end of laryngoscope, cause intubate smoothly, and finish because the operating time of intubate was limited in 7 minutes,, bring influence can for patient's life rescue just in case intubate is improper;
2, handle and arc oropharyngeal airway and pressure tongue cover board component are all vertically arranged, during operation, the doctor need finish the pressure tonguing with entire arms, inconvenient operation, especially at the patient of vertebrae injry or the patient of strong spinal column, patient's head can not move, and can not proofread and correct patient's mouth position, operating difficulties by the head of removing patient.
The utility model content
, inconvenient operation long for the handle that overcomes existing visual laryngoscope, to the demanding deficiency of doctor's operating experience, this utility model provide a kind of can effectively shorten decreased food, easy to operate, doctor's operating experience is required lower electric video laryngoscope.
The technical scheme that its technical problem that solves this utility model adopts is:
A kind of electric video laryngoscope, comprise carriage assembly, arc oropharyngeal airway and pressure tongue cover board component, camera assembly, battery case and display, described arc oropharyngeal airway and pressure tongue cover board component are positioned at the front end of carriage assembly, described camera assembly is positioned at described arc oropharyngeal airway and presses the bottom of tongue cover board component, described camera assembly comprises photographic head and illuminating lamp, described display is installed in rotation on the carriage assembly, described photographic head is connected with described display by data wire, described battery case is by electric wire and illuminating lamp, photographic head is connected with display, described electric video laryngoscope also comprises the battery cover box of holding concurrently to operating grip, described battery case is installed in the described battery cover box, and described battery cover box is installed in the side of described carriage assembly.
Further, described display is installed in the display box, and described display box is connected with the rear end of described carriage assembly by universal joint.
Further again, the lower end of described arc oropharyngeal airway and pressure tongue cage plate module back is the indent arc, described camera assembly also comprises the camera assembly cavity, photographic head and illuminating lamp are installed in the front end of camera assembly cavity, the end face of described camera assembly cavity is outer convex, and described arc oropharyngeal airway and pressure tongue cover board component are connected with described camera assembly cavity.
Described camera assembly cavity rear end is provided with dop, and the front end of described carriage assembly is provided with draw-in groove, and described dop is connected in the described draw-in groove.
