detailed description

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations.

Referring to FIGS. 1-3 , a video laryngoscope with a protective channel is shown in the figures, including a handle 100 , a laryngoscope blade 300 and a display 200 .

The monitor 200 is arranged on the top of the handle 100, and the laryngoscope blade 300 has the same arc structure as the physiological curvature of the oral cavity and throat when the human body is in a natural position. A camera 500 is provided, and a light emitting device 600 is provided near the camera 500 , and the camera 500 is connected to the display 200 in communication.

In this embodiment, the light-emitting device 600 is an LED lamp bead. Since the LED is a cold light source, it will not generate a lot of heat, and thus will not cause a lot of discomfort to the patient.

The video laryngoscope with a protective channel also includes an arc-shaped block 400 that is detachably arranged on the laryngoscope piece 300, and forms a gap between the arc-shaped block 400 and the side of the laryngoscope piece 300, which can accurately insert the trachea. The protection channel 700 to the inside of the respiratory tract, with this structure, not only can the position of the glottis be accurately observed, but also the trachea can be inserted into the respiratory tract accurately, and at the same time, it can effectively avoid injuring the glottis or other parts of the oral cavity. parts.

One side of the arc-shaped block 400 is hinged on one side of the laryngoscope blade 300, the other side of the arc-shaped block 400 is provided with a clip 410, and the other side of the laryngoscope 300 is provided with a clip corresponding to the clip 410. The other side of the arc-shaped block 400 is engaged with the engaging slot 310 on the other side of the laryngoscope blade 300 through the engaging feet 410 .

The arc-shaped block 400 is made of soft and tough material, such as nylon, which can prevent the arc-shaped block from scratching the oral cavity, relieve the patient's discomfort, and avoid causing harm to the patient.

When performing endotracheal intubation, first buckle the other side of the arc-shaped block 400 on the other side of the laryngoscope blade 300, then extend the laryngoscope blade 300 into the patient's mouth, and pass the trachea through the protective channel The trachea is accurately inserted into the airway, and finally the laryngoscope blade 300 is taken out from the patient's mouth, and the arc-shaped stopper 400 is opened to remove the laryngoscope.

The position of the end opening of the protective channel 700 corresponds to a fixed alignment mark 800 on the display 200. When the display 200 is aligned with the glottis opening, it means that the end opening of the protective channel 700 is facing the glottis. At this time, the intubation tube and endotracheal tube head The end of the catheter can face the glottis to ensure successful intubation and avoid damage to the local tissue of the glottis due to manual misalignment of the glottis during conventional intubation, and the catheter is limited to the protective channel 700 to avoid damage to the mandible and posterior pharyngeal wall during conventional difficult intubation Scratch scratches.

In summary, the utility model also includes a detachable arc-shaped baffle set on the laryngoscope blade, and a protective channel is formed between the arc-shaped baffle and the side of the laryngoscope blade to accurately insert the trachea into the interior of the respiratory tract. With this structure, not only can the position of the glottis be accurately observed, but also the head end of the trachea can be inserted into the airway accurately. At the same time, due to the protection of the protective channel, even if it is difficult to intubate, it will not be caused by the catheter being in place when the catheter is pushed. The twisting and scratching in the oral cavity will damage the surrounding tissues and reduce the incidence of complications of difficult intubation.

The basic principles, main features and advantages of the present utility model have been shown and described above. Those skilled in the industry should understand that the utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions only illustrate the principle of the utility model. The utility model does not depart from the spirit and scope of the utility model There will also be various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model. The scope of protection required by the utility model is defined by the appended claims and their equivalents.
