When the cover body is completely covered on the mirror body, the transparent layer is opposite to the end of the mirror body, and the elastic ring is just covered on the outer periphery of the tracheal tube fixer.

[0007] The beneficial effect of the above scheme is that when the sleeve body is completely arranged on the periphery of the scope, the elastic ring is connected to the endotracheal tube fixer, so that the sleeve body keeps completely covering the scope body. At this time, when using it, the scope body will not directly contact the patient. After use, only the protective sleeve needs to be replaced.

[0008] The above-mentioned video laryngoscope also has the following characteristics: the tracheal tube fixer includes a positioning body and a sleeve body, the positioning body and the sleeve body are both sleeved on the periphery of the scope body, the positioning body is provided with a positioning portion for fixing the positioning body and the scope body, and the sleeve body is provided with an annular protrusion on the periphery of the sleeve body.

[0009] The beneficial effect of the above scheme is that the position of the positioning body on the mirror body can be adjusted through the positioning part. When the positioning body is fixed, the elastic ring is set on the outer periphery of the sleeve body. When the elastic ring passes over the annular protrusion, the protective cover can remain on the mirror body.

[0010] The above-mentioned video laryngoscope also has the feature that the number of the annular protrusions is at least three, and the plurality of annular protrusions are distributed in parallel and at intervals around the outer periphery of the positioning body.

[0011] The beneficial effects of the above solution are as follows: the plurality of annular protrusions are distributed at intervals, and a groove is directly reserved between every two annular protrusions for the elastic ring to be inserted into.

[0012] The above-mentioned video laryngoscope also has the following characteristics: the locking assembly includes a tightening body and a locking hoop, the tightening body is an elastic body with an opening on one side, the tightening body is sleeved on the outer periphery of the sleeve body, and the locking hoop is sleeved on the outer periphery of the tightening body. When the tightening knob of the locking hoop is rotated, the locking hoop is gradually tightened, causing the tightening body to deform, thereby pressing the elastic ring sleeved on the outer periphery of the sleeve body onto the sleeve body.

[0013] The beneficial effect of the above solution is that the tightening body is deformed by the locking hoop, and the elastic ring is pressed against the sleeve body, which can further prevent the protective cover from slipping off.

[0014] In summary, the beneficial effects of this scheme are:

[0015] In the video laryngoscope provided by the utility model, the protective cover is sleeved on the mirror body to avoid the mirror body from needing to be cleaned and disinfected each time it is used, and the sleeve body and the locking assembly cooperate with each other to achieve the effect of preventing the protective cover from slipping off. The video laryngoscope provided by the utility model simplifies the work of medical staff and avoids the need to clean and disinfect the mirror body each time it is used.
