Description
Technical field
The present invention relates to a kind of double positioning tracheal cannula visual devices.
Background technology
The video laryngoscope of existing trachea cannula（As shown in Figure 1）, its laryngoscope is designed as：There is the arc of certain radian
Eyeglass, its inner arc are the arc-planes for having one fixed width, and first half is 30 to 50 millimeters long of spatula, to provoke patient
Epiglottis exposure glottis；An outer arc part for Arc lenses is the tube chamber of installation pick-up lens, and a part is the row of trachea cannula
Enter space.Because the radian of eyeglass spatula bending is big, the difficulty of trachea cannula also accordingly increases.
The content of the invention
The purpose of the present invention, is to provide for a kind of double positioning tracheal cannula visual devices, the theory of its design with
The design concept of traditional laryngoscope has difference substantially, is designed using the method for opposition thinking, by by the present invention's
Front end is directly sent to the position between " air flue and esophagus ", glottis is located at the top of front end of the present invention, overcomes existing regard
Frequency laryngoscope spatula top is especially solved under difficult airway situation, gas to " being intubated uncontrollable area " between video lens
The problem of cannula difficulty.
The present invention is achieved in that a kind of double positioning tracheal cannula visual devices, and it includes device Host
Mechanism, display, the first half of device Host mechanism are " J " shape conduit guiding bar for meeting human oral cavity arcuate structure, equipment
The latter half of of main unit mechanism is handle；The left and right sides that double positioning refer to " J " shape conduit guiding bar front end is one in front and one in back provided with
Two groups of high-definition camera camera lenses and lighting source；The both sides up and down of " J " the shape conduit guiding bar front end are respectively provided with phlegm suction inlet, are used for
Clean oral cavity；Supply pipeline opening is provided between the high-definition camera camera lens and lighting source of " J " the shape conduit guiding bar front end, is used
In feedwater or oxygen supply or administration；The section of " J " the shape conduit guiding bar is " u "-shaped, and trachea cannula is along "u"-shaped groove
Bottom land inserts air flue.
The both sides up and down of " J " shape conduit guiding bar front end of the present invention are respectively provided with phlegm suction inlet, the phlegm being connected with phlegm suction inlet
Suction pipe road is located at the both sides of J " shape conduit guiding bars.
Supply pipeline is provided between the high-definition camera camera lens and lighting source of " J " shape conduit guiding bar front end of the present invention
Mouthful, the supply pipeline being connected with supply pipeline opening is located at the both sides of J " shape conduit guiding bars.
Handle of the present invention is made up of three parts, is respectively：Handle and " J " shape conduit guiding bar connection unit, handle
Internal cell storehouse, handle and indication mechanism connection unit；The handle and " J " shape conduit guiding bar connection unit be respectively equipped with into
Oxygen, intake, enter medicine interface, and suction sputum interface.
The invention has the advantages that " J " shape conduit guiding bar of the present invention, i.e., into the part in human oral cavity,
With a certain degree of bending, to be adapted to the arc physiological structure of the human oral cavity root of the tongue.The inner arc design of " J " shape conduit guiding bar
For "u"-shaped groove, the outer arc of " J " shape conduit guiding bar is smooth curved surface, and it is very smooth to be contacted with human oral cavity.It is double to position what is referred to
It is that " J " shape conduit guiding bar front end can be pushed directly to the position between the lower end i.e. glottis of glottis and esophagus, preceding high definition is taken the photograph
As camera lens it is observed that the accurate location of glottis, and show over the display；" J " shape conduit guiding bar front end is reached under glottis
After the position at end, now trachea cannula is down pushed away along the "u"-shaped groove on the inside of " J " shape conduit guiding bar, trachea cannula one
The front end that denier leaves " J " shape conduit guiding bar can enter glottis, and rear high-definition camera camera lens is observing and confirm trachea cannula
Really air flue is inserted, is intubated successfully；Afterwards high-definition camera lens shooting to video can also show over the display.
