The utility model provides a laryngoscope, it is spacing to pipe 20 through first spacing hole 101 and the spacing hole 102 of second, pipe 20 wears to take place to buckle behind first spacing hole 101 and the spacing hole 102 of second, therefore only drive body 10, to the in-process of pipe 20 application of force, pipe 20 leads to pipe 20 and body 10 to form fixedly because of being spacing and buckling, pipe 20 and body 10 integration, make pipe 20 be in the first operating condition that can follow body 10 synchronous motion, because pipe 20 carries on spacingly through first spacing hole 101 and the spacing hole 102 of second, therefore, when driving pipe 20, pipe 20 can slide along first spacing hole 101 and the spacing hole 102 of second, pipe 20 is in the second operating condition that relative body 10 removed promptly.

When the laryngoscope according to the present embodiment is used, an endotracheal intubation procedure will be described as an example:

as shown in fig. 2, when the operator only drives the body 10 to move into the patient's mouth, the body 10 will carry the conduit 20 together to move into the patient's mouth, so that the end of the laryngoscope reaches the throat of the patient, and the conduit 20 is at the first position (a) shown in fig. 2, and after the patient's entrance to the trachea is exposed by the body 10, the conduit 20 is in the second working state by applying force to the conduit 20, so that the conduit 20 is inserted into the trachea of the patient, and the conduit 20 is at the second position (b) shown in fig. 2.

Therefore, according to the laryngoscope provided by the embodiment, the conduit 20 is in place (reaches the throat part of the patient) along with the body 10 in one step, and the conduit 20 does not need to be controlled independently to enter the oral cavity, so that the operation steps are simplified, the labor is saved, the operation is convenient, the operation time is saved, the operation efficiency is improved, and particularly, the gold time for rescue is greatly saved in the treatment of critically ill patients. In addition, the first limit hole 101 and the second limit hole 102 can circumferentially limit the conduit 20 through the inner walls of the holes, and in the process that the conduit 20 moves along with the body 10, the conduit 20 is effectively prevented from moving in the radial direction of the limit hole, namely, in the direction away from the body 10, so that the probability that the conduit 20 moves to damage the oral cavity of a patient is reduced, the conduit 20 is prevented from moving to block the trachea cannula from going on smoothly, the operation is more convenient, and the success rate of disposable intubation is improved.

In one embodiment, as shown in fig. 2, the body 10 is provided with a wire cavity 11, and the upstream of the wire cavity 11 is provided with a through section 12 communicating with the first limiting hole 101 for passing the conduit 20.

Through setting up lead wire chamber 11, can accomodate the connecting wire of the camera element of setting on body 10, reduce the connecting wire and expose, reduce the probability that the electric leakage accident takes place. The lead wire cavity 11 makes the body 10 hollow, which helps to reduce the total weight of the body 10 and facilitates flexible operation. In addition, the connecting wire is prevented from contacting with the oral cavity of a human body, the whole device is sterilized after the use is convenient, and the sanitation of the device is ensured. The upper reaches of lead wire chamber 11 set up through section 12, and through section 12 limits the track that the straight line of pipe 20 slided with first spacing hole 101 jointly, and pipe 20 can adapt to the less space of human throat along through section 12 rectilinear movement, avoids pipe 20 skew body 10, consequently, prevents that pipe 20 from touching patient's throat and causing the damage.

It should be noted that the storage of the connection wire is not limited to be realized through the lead wire cavity 11, for example, in another embodiment, as shown in fig. 3, a lead wire groove 13 and a buckle 14 are arranged at the upstream of the body, and the connection wire is compressed in the lead wire groove 13 through the buckle 14, so that the storage of the connection wire is realized, and the danger of the movement of the connection wire is avoided.

In a preferred embodiment, as shown in fig. 2, the end of the body 10 is provided with a stopping portion 15, the stopping portion 15 is located outside the lead cavity 11, and the stopping portion 15 is formed with a second limiting hole 102.

The stopping portion 15 is provided with a second limiting hole 102, so that the catheter 20 is prevented from interfering with a connecting wire and the like in the lead wire cavity 11 during the moving process, and the stopping portion 15 plays a role in limiting and fixing the catheter 20 during the process that the catheter 20 enters the oral cavity of the patient along with the body 10. One side of the stop 15 may also serve as a tongue depressor 151 to facilitate manipulation and to expose the view in the throat.

In a more preferred embodiment of the present embodiment, as shown in fig. 3, the main body 10 is provided with a fixing portion 16 for attaching an image pickup device (such as an endoscope), and the stopper portion 15 is provided with a cutout groove 152 for avoiding image blockage on a side facing the fixing portion 16.

Realize the installation of the component of making a video recording through fixed part 16, form through breach groove 152 and dodge, avoid backstop portion 15 to cause to block the angle of making a video recording and the blind area of making a video recording appears, and then guarantee the success rate of intubate.

In another more preferred embodiment of the present embodiment, as shown in fig. 4, the downstream a portion of the lead cavity 11 is inclined with respect to the upstream B portion of the lead cavity 11 to form an escape space between the stopper portion 15 and the through section 12, and the guide tube 20 passes through the through section 12, passes through the escape space, and then passes through the second stopper hole 102.

With reference to fig. 4, by forming the avoiding space, the operator can conveniently install the guide tube 20 in the preparation stage of the operation, and only needs to penetrate the guide tube 20 out of the through section 12, and bend the guide tube 20 in the avoiding space to penetrate the second limiting hole 102 to form fixation, so that the installation is rapid, the resistance in the installation process is small, and the operation is simple. In addition, in the operation process, after the catheter 20 is inserted into the trachea of the human body and fixed, the body 10 needs to be moved out of the oral cavity of the patient independently, so that the avoiding space reduces the friction between the catheter 20 and the body 10, and the movement of the body 10 is facilitated.
