The bite-block of trachea cannula.
In order to achieve the above-mentioned object of the invention, the utility model uses technical solution as described below:
It is a kind of for fixing the bite-block of trachea cannula, including bite-block main body, it is characterized in that: the bite-block main body is spacious in both ends
The hollow cylindrical of mouth, is provided with the fixed part for fixing trachea cannula, the fixed part on the exterior arc surface of bite-block main body
It is to be detachably connected with bite-block main body.
Preferably, the fixed part includes the snap ring for being symmetricly set on bite-block main body two sides, and snap ring is elastomeric material,
Snap ring is C-shape, and the notch of snap ring is outside.
Preferably, it is provided with connecting screw on the snap ring, the spiral shell being arranged in bite-block main body is rotatably connected in by connecting screw
The interior realization snap ring of line through-hole is fixedly connected with bite-block main body.
Preferably, the tapped through hole in bite-block main body is provided at least two, length of all tapped through holes along bite-block main body
Degree direction interval is evenly arranged.
Preferably, the snap ring being arranged on the every side of bite-block main body is provided at least two.
Preferably, elastic rubber set is coated on the exterior arc surface of bite-block main body.
Preferably, it is provided with connection otic placode on the exterior arc surface of bite-block main body, offered in connection otic placode for tying up
The bandage hole of restraint strap.
Preferably, snap ring is that spherical pair is connect with connecting screw, and snap ring can rotate on connecting screw.
Preferably, snap ring is made of two arc panel elastic hinge joints, is connected after one end elastic hinge joint of two arc panels
In the openings of sizes on connecting screw, forming the other end of two arc panels by the elastic hinge joint of two arc panel one end
It can adjust.
Due to the adoption of the above technical scheme, the utility model has following superiority:
Compared with existing bite-block, the bite-block main body in the utility model is cylindrical, patient can be made to use in this way
When, the lip contact area of bite-block main body and patient are small, for a long time with will not generate pressure injury；In addition, in bite-block
Elastic rubber set is coated on body outer surface, so that patient will not damage teeth pad main body；In addition, in bite-block main body
It is upper to make the fixation of trachea cannula more convenient reliable by the way that snap ring is arranged, then by the effect of restraint strap, so that this is practical new
The bite-block of type when in use, will not be skidded off out of patient oral cavity.
