Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

The utility model aims at providing a visual intubate laryngeal mask adjusts through the position and the angle to first port to the position of placing to the camera is adjusted, can guide trachea cannula to the disease trachea by the first side of cover body plane of symmetry, avoids trachea cannula touching epiglottis and shelters from the observation angle of camera.

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description. As used herein, "upper airway end" and "upper esophageal end" refer to the end of the body that is adjacent to the head of a patient. In addition, the visual intubation laryngeal mask can be used for not only humans but also animals.

Referring to fig. 1 to 3, the present embodiment provides a visual intubation laryngeal mask 100, which includes a main tube 1 and a mask body 2, wherein one end of the main tube 1 is connected to the mask body 2. The main tube 1 is provided with a first channel 11 through which an air supply tube cannula or bronchofiberscope passes, and the first channel 11 has a first port 111 located on the mask body 2. The cover body 2 has a symmetrical surface 21, and a placing position 22 for placing a camera is arranged on the cover body 2. The first port 111 is located at a first side a of the plane of symmetry 21, the first port 111 being inclined towards the plane of symmetry 21. The placement site 22 is located at the second side B of the symmetry plane 21. Here, "obliquely oriented" means that the first port 111 is oriented neither parallel to the symmetry plane 21 nor perpendicular to the symmetry plane 21, for the same reason as described below. In use, the first port 111 is directed towards the upper end of the trachea.

When the visual intubation laryngeal mask 100 is used, after the endotracheal tube or the bronchofiberscope is inserted into the first channel 11, the endotracheal tube or the bronchofiberscope extends out from the first port 111, and enters the trachea of the patient from the first side a of the symmetry plane 21 at a certain angle under the guidance of the first port 111, so that the endotracheal tube or the bronchofiberscope is prevented from touching the epiglottis. Meanwhile, because the first port 111 of the first channel 11 and the placement position 22 of the camera are respectively located on two sides of the symmetry plane 21, the epiglottis is prevented from being shielded by a tracheal cannula or a bronchofiberscope when the epiglottis is photographed by the camera.

The angle of the first port 111 can be flexibly selected by those skilled in the art as needed. For example, referring to FIG. 1, in the present embodiment, the axis of the first port 111 forms a first included angle α,7 ≦ α ≦ 20, with respect to the plane of symmetry 21.

The camera can transmit shooting data to the external display equipment in a wireless communication mode, and can also transmit the shooting data to the external display equipment through a wire. Referring to fig. 1-3, in the present embodiment, the main tube 1 is provided with a second channel 12 for the camera and the lead thereof to extend into, the second channel 12 has a second port located on the cover body 2, and the location of the second port is the placement position 22. The second port is inclined towards the plane of symmetry 21. When the device is used, the camera does not extend out of the second port or partially extends out of the second port, so that the shooting angle of the camera can be positioned through the contact of the second port and the camera, and the camera is aligned with the epiglottis.

The angle of the second port can be flexibly selected by those skilled in the art according to the needs. For example, referring to FIG. 1, in the present embodiment, the axis of the second port forms a second angle β with the plane of symmetry 21, with β being 0.5 ≦ 8.

Referring to fig. 1-3, in order to prevent aspiration caused by regurgitation of the stomach, in this embodiment, the main tube 1 is provided with a third channel 13 for passing the esophageal drainage tube, the cover body 2 is provided with a fourth channel 23 for passing the esophageal drainage tube, one end of the fourth channel 23 is communicated with the third channel 13, the other end of the fourth channel 23 forms a third port on the cover body 2, and the third port is located at one end of the cover body 2 away from the main tube 1. In use, the third port is directed towards the upper end of the patient's esophagus. When the visual intubation laryngeal mask 100 is used, the esophageal drainage tube can extend into the esophagus along the third channel 13 and the fourth channel 23 to suck gastric reflux.

Referring to fig. 1 to 3, in order to avoid the fog or the body fluid of the patient from contaminating the window or the mirror surface of the camera to affect the shooting effect, in the present embodiment, the main pipe 1 is provided with a fifth channel 14 for the cleaning pipe to pass through. When the visual intubation laryngeal mask 100 is in use, the cleaning tube can be passed through the fifth channel 14, and the mirror surface of the window or the camera can be washed or flushed by cleaning liquid in the cleaning tube. The window is usually a structure which is arranged on the cover body 2 and is positioned between the camera and the epiglottis, and when the window is arranged on the cover body 2, only the window can be washed. When the window is not arranged on the cover body 2, the mirror surface of the camera can be washed.

In order to be able to extend the endotracheal tube or bronchofiberscope while maintaining ventilation, the present embodiment further comprises a three-way connection (not shown in the drawings). The first end of the three-way joint is communicated with the first channel 11, the second end of the three-way joint is used for being connected with a breathing machine, the third end of the three-way joint can be opened and closed, and when the three-way joint is opened, an air supply pipe cannula or a bronchofiberscope penetrates through the three-way joint. The opening and closing of the third end of the three-way joint can be realized by the disassembly and the installation of a rubber plug or other sealing elements.

Referring to fig. 4, in order to facilitate the cover body 2 to extend into the throat, in this embodiment, the main tube 1 is integrally curved in an arc shape, and the bending angle is γ, γ is greater than or equal to 95 degrees and less than or equal to 160 degrees, so as to adapt to the physiological structure between the oral cavity and the throat of a human body.

Referring to fig. 1-4, in this embodiment, the cover 2 includes an airbag. The air bag can deform so as to keep close contact with the throat part of a human body and avoid the injury of human tissues. However, example embodiments are not limited thereto. For example, the mask body 2 may further include a mask body and a rubber pad mounted on the mask body, the rubber pad is in close contact with the throat of the human body, and the rubber pad may be a silica gel pad.
