As shown in fig. 1 to 4, the soft visual laryngoscope of the disclosure comprises a laryngoscope body 1 and a tongue depressing mechanism.
The laryngoscope body 1 is internally provided with a suction channel 11. The entrance to the suction channel 11 is at the capture end of the laryngoscope body 1. The inlet of the suction channel 11 is an inlet for contaminants such as secretions and blood in the oropharyngeal cavity, and contaminants may enter the suction channel 11 from the inlet of the suction channel 11. The outlet of the suction channel 11 can be positioned on the body or the laryngoscope handle of the laryngoscope body 1, and pollutants can leave the soft visible laryngoscope from the outlet of the suction channel 11. The shooting end of the laryngoscope body 1 refers to the end of the laryngoscope body 1 provided with the lens.
The tongue depressing mechanism includes a tongue depressing plate 2 and a suction duct 3. The tongue depressor 2 is connected with the shooting end of the laryngoscope body 1. The tongue depressor 2 extends generally away from the capture end of the laryngoscope body 1. The position of the tongue depressor 2 can also be changed along with the adjustment of the position of the shooting end of the laryngoscope body 1. The inlet of the suction duct 3 is communicated with the outside, the outlet of the suction duct 3 is connected with the inlet of the suction channel 11, and the suction duct 3 extends along the tongue depressor 2 towards the direction far away from the shooting end of the laryngoscope body 1. The shape of the inlet, outlet and cross-section of the suction pipe 3 can be flexibly selected according to the actual requirements, for example, the shape of a circle, an ellipse or a rectangle. The connection between the outlet of the suction duct 3 and the inlet of the suction channel 11 may be achieved by means of an integral molding or a pipe connection. By connecting the suction line 3 and the suction channel 11 together, the suction line 3 and the suction channel 11 form a complete channel for the passage of contaminants.
The inlet of the suction tube 3 is an inlet for contaminants such as secretions and blood in the oropharyngeal cavity, and the outlet of the suction tube 3 is an outlet for contaminants. The contaminants may enter the suction duct 3 from the inlet of the suction duct 3 and enter the suction channel 11 from the outlet of the suction duct 3.
The suction duct 3 may not be connected to the tongue depressor 2, for example, the suction duct 3 is supported only on the tongue depressor 2. Alternatively, the suction duct 3 may be connected to the tongue depressor 2 by welding or integrally molding.
In practice, the inlet of the suction duct 3 may be located on the upper, lower or side surface of the tongue depressor 2. In order to more conveniently attract contaminants, the inlet of the attraction duct 3 may be located on the lower surface of the tongue depressor 2, that is, on the surface of the tongue depressor 2 adjacent to the photographing end of the laryngoscope body 1.
When the soft visual laryngoscope is used, the laryngoscope body 1 is firstly inserted into the pharyngeal cavity of a patient, when the soft visual laryngoscope encounters pollutants such as secretion, blood and the like in the oropharyngeal cavity, the front end of the laryngoscope body 1 is bent forwards by adjusting the angle trigger, and the tongue depressor 2 is bent forwards at the moment to drive the inlet of the suction pipeline 3 to be contacted with the pollutants. The pollutant enters the suction channel 11 from the suction pipeline 3 and is finally sucked out of the body, so that the aim of preventing the lens of the laryngoscope body 1 from being polluted by the pollutant is fulfilled.
The suction pipe 3 of the soft visual laryngoscope of the disclosure contacts with the pollutant before the laryngoscope body 1, the pollutant flows through the suction pipe 3 and the suction channel 11 and is sucked out of the soft visual laryngoscope, thereby effectively avoiding the pollutant from polluting the lens of the laryngoscope body 1.
In one embodiment of the soft visual laryngoscope of the present disclosure, the suction tube 3 is connected with the tongue depressor 2. The connection between the suction duct 3 and the tongue depressor 2 can be achieved by welding or by means of an integral moulding. By connecting the suction duct 3 with the tongue depressor 2, the suction duct 3 can be supported by the tongue depressor 2 more efficiently and reliably. Furthermore, connecting the suction duct 3 to the tongue depressor 2 also facilitates a more flexible movement of the suction duct 3 with the tongue depressor 2.
In one embodiment of the soft visual laryngoscope of the present disclosure, the inlet of the suction tube 3 is spaced from the end of the tongue depressor 2 remote from the laryngoscope body 1. That is, the length of the suction duct 3 should be smaller than the length of the tongue depressor 2. This arrangement is advantageous in improving the comfort of use of the soft laryngoscope and also in improving the efficiency of attracting contaminants.
In one embodiment of the soft visual laryngoscope of the present disclosure, in order to more rapidly suck away contaminants, the plane in which the inlet of the suction tube 3 is located forms an acute angle with the surface of the tongue depressor 2.

Contaminants enter the suction channel 11 from the entrance of the suction channel 11 on the laryngoscope blade 12 and exit the suction channel 11 from the exit of the suction channel 11 on the laryngoscope handle 13.
In particular, an outwardly extending pipe may be provided at the outlet of the suction passage 11 to further improve the convenience of operation.
As shown in fig. 1-5, the present disclosure also provides an endotracheal intubation device including a suction unit (not shown in the figures) and the flexible visual laryngoscope of the present disclosure.
The suction unit may be used to provide suction to the suction channel 11 to suck contaminants out of the suction channel 11. The suction unit may be, for example, a negative pressure aspirator or a suction pump, etc. In specific implementation, the suction unit is connected with the outlet of the suction channel 11, so that pollutants can be sucked out of the oropharyngeal cavity and the flexible visible laryngoscope.
In one embodiment of the endotracheal intubation device of the present disclosure, the endotracheal intubation device further includes an intubation mechanism. The cannula mechanism comprises a guide 4. In particular implementations, the guide 4 may have a tubular configuration to provide oxygen to the patient during intubation of the endotracheal tube.
