Description
Technical field
The present invention relates to medical treatment and nursing equipment technology field, is specifically a kind of oral trachea cannula fixing device.
Background technology
Endotracheal intubation is successfully to rescue one of important measures of urgent patient, and traditional trachea cannula fixing means is always
It is to continue to use bite-block and trachea cannula with patient both sides cheek is adhered directly onto after immobilization with adhesive tape again, since fixing means is simple and crude,
Therefore there are many drawbacks；Using immobilization with adhesive tape, often patient is not felt like oneself, stimulate skin to trigger inflammation or epidermis to fester；Adhesive plaster stays
It is agglomerating to put the easy adhesion of overlong time, is not easy to replace, and easily pollution causes secondary infection, is caused additionally to patient
Pain.Occur dedicated tracheal cannula fixer or fixing device in recent years, be placed on oral area, play fixed tracheae and insert
The effect of pipe.
Authorization Notice No. is that the Chinese patent of CN 103480074B discloses a kind of fixator for tracheal cannule, including tooth
Pad, the bite-block include bite and intubation fixed part, and the bite is adapted with the tooth of oral cavity side, is intubated fixed part

As shown in Figs. 1-5, a kind of oral trachea cannula fixing device, including stent 1, bite-block 2 and fixed band 3, Gu
Fixed band is preferably the elastic webbing with elasticity capacity, can combine the prior art in the art, in order to be fixed on head, carry
The comfort that height uses；The stent includes stage casing 11 and is symmetrical set in stage casing transverse ends and is integrally formed with stage casing
Two sides section 12, the stage casing and two sides section composition glasses frame-shaped, it is described while section have rectangular through-hole 121 and while section it is outer
End is equipped with the perforation 122 for being used for connecting fixed band, and the size of perforation is adapted with fixed band, and preferably stage casing is straight panel shape, is risen
To excessive or two sides sections of connection support effects；
The bite-block includes the upper bite-block 21 of vertical side walls rotation connection same with rectangular through-hole and lower bite-block 22 respectively, and
The vertical side walls of the rectangular through-hole are close to stage casing side, and the upper bite-block is identical with lower gripper pad structure and spacing is set, two sides
The insulating space of tooth, namely the accommodating space of trachea cannula are formed between upper bite-block and lower bite-block in section, avoids tooth from stinging
Close on trachea cannula；
The first fixed mechanism 4 is further included, first fixed mechanism includes fixture block body 41, is arranged on fixture block body upper table
Face and in the lower semi-ring 42 of semicircle shape, be located at stage casing lower surface and upper half ring 43 to stage casing indent, be arranged on fixture block body before
The block tongue 44 at end and the card slot 45 for opening up one side section wherein and the indention close to stage casing side, the block tongue and card slot
It is adapted, the fixture block body rear end connects with another side section and close stage casing side squash, and the upper half ring is mutually fitted with lower semi-ring
Should, and the fixed space 5 of trachea cannula is formed therebetween, fixture block body rear end connects structure type with another side section ball, with reference to
Machinery field common technical knowledge, fixture block body can carry out circumferential rotation or rotary action around the ball place of connecing, can also carry out space
The rotation of interior any angle scope, concrete structure do not repeat herein；
The second fixed mechanism 6 is further included, the tracheae that second fixed mechanism is used to fix on the outside of the fixed space is inserted
Tube portion, namely the part positioned at stent front side or being managed except the part outside fixed space away from oral area side
Section, and the fixed-direction of the second fixed mechanism forms angle with the fixed-direction of upper half ring and lower semi-ring, namely such as above-mentioned technology
The fixed-direction of scheme, upper half ring and lower semi-ring is and the fixed-direction of the second fixed mechanism in vertical direction straight up
For non-vertical direction, its fixed-direction differs, so as to improve the stability fixed to trachea cannula.
Improved as to the further of above-mentioned technical proposal, second fixed mechanism includes being installed in two side sections respectively

Bite-block uses the structure type with side section rotation connection, can be turned when needing bite-block to cradle back, to extend entrance
Chamber, plays the buffer action to tooth, during without bite-block, can be turned out, will not stretch into oral cavity, easy to use,
So as to meet different actual use needs.
As a kind of preferable technical solution, another described extension is equipped with notch 611, and the bandage other end is set
There is the ring buckle 621 to match with the notch, when fixed, by ring buckle hanging sleeve on notch ring buckle can be avoided to slide, Gu
Fixed connection and dismounting are all very convenient.
As a kind of preferable technical solution, the bandage is made of elastic material, namely bandage preferably has elastic energy
Power, can in trachea cannula by external force when factor when acted on buffering, and then ensure the first fixing device stability, improve
To the stability maintenance and reliability of trachea cannula entirety.
As a kind of preferable technical solution, the rotational angle range of the bite-block is 0-90 degree, at 0 degree, the bite-block
It is non-bulging in the back side of stent to take in completely in the rectangular through-hole so that bite-block avoids contacting with oral area, will not make
Into extra interference effect, comfort is improved；At 90 degree, the back side of the bite-block and stent is perpendicular, perpendicular state
When, bite-block can stretch into oral cavity the effect for playing isolation, herein preferably in the upper surface of upper bite-block and the lower surface of lower bite-block
The flexible layer such as silica gel is set, avoid with tooth hard contact, ensure that tooth is injury-free, so as to meet different use need
Will.
As a kind of preferable technical solution, the spacing between the upper surface of the upper bite-block and the lower surface of lower bite-block is big
In the outside diameter equal to trachea cannula, and the fixed position of the trachea cannula is located at the upper surface of upper bite-block and the following table of lower bite-block
Between face, it is ensured that when trachea cannula is fixed between upper lower teeth, meet that the isolation to tooth becomes to avoid dental articulation
The use function of shape needs.
As a kind of preferable technical solution, antiskid rubber 46 is equipped with the inner ring surface of the upper half ring and lower semi-ring,
Be conducive to increase and the frictional force on trachea cannula surface, improve stability maintenance.
As a kind of preferable technical solution, the fixture block body is equipped with operation portion 411, sets operation portion, can be easy to
Operation rotates fixture block body, to improve operability.
As a kind of preferable technical solution, the vertical projection of the stent is arc-shaped, in favor of mutually being fitted with facial contours
Should, improve comfort.
Explanation and embodiment above is only exemplary, does not form any restrictions to the scope of the present invention.This area
