The terms "mounted," "one end," "the other end," and the like are used herein for illustrative purposes only.

Please refer to fig. 1 and 2, an embodiment of the present invention provides a visual inflation-free laryngeal mask, which comprises a tube body 1, a mask body and a camera module, wherein the mask body comprises a mask body portion 21, a first opening portion 22 and a second opening portion 23, the first opening portion 22 and the second opening portion 23 are located in the mask body portion 21, the first opening portion 22 is communicated with the second opening portion 23 through a funnel-shaped channel, the second opening portion 23 is connected with a tube opening of a patient end of the tube body 1, and an included angle between a patient end face of the first opening portion 22 and a machine end face of the second opening portion 23 is 40-70 degrees, so that the mask body portion 21 can adapt to the structure of a body cavity channel, and discomfort of a patient is reduced. The patient end and machine end are referred to herein with reference to the operator, the "patient end" being the end at a greater distance from the operator, and the "machine end" being the end at a lesser distance from the operator, specifically the left and right ends of fig. 1 and 2. The machine end of the tube 1 may be connected to a laryngeal mask connector 11, and the laryngeal mask connector 11 may be connected to a ventilator or anaesthetic machine (not shown). The camera module comprises a camera 31, a camera lead 32, a camera joint 33 and a camera channel 34, wherein the camera channel 34 is embedded in the inner walls of the pipe body 1 and the cover body 21, one end of the camera channel penetrates through the cover body 21, and the other end of the camera channel is located at the machine end of the pipe body 1. The camera 31 is disposed in the cover body 21 and located in the patient end of the camera channel 34, and the camera 31 can be fixed in the camera channel 34 by gluing or blocking. The camera wire 32 passes through the camera passage 34, and one end of the camera wire 32 is connected to the camera 31 and the other end is connected to the camera connector 33. Camera joint 33 can be the USB interface, all sets up outside body 1, and camera 31's photographic picture passes through camera wire 32 and camera joint 33 and transmits to display device, supplies medical personnel to observe.

Referring to fig. 2, the camera 31 is disposed in the mask body 21 and near the patient end of the second opening 23, so that the field of view of the camera 31 is clearer, the whole inserting process of the laryngeal mask can be monitored by dynamic video, the laryngeal mask inserting operation can be performed visually, the damage to the body cavity caused by the front end of the laryngeal mask due to 'blind insertion' is reduced, the inserting time is effectively shortened, and the pain of the patient is relieved.

The utility model provides a visual laryngeal mask of exempting from to aerify, body 1 and the cover body 21 integrated into one piece to make by flexible material, because the silica gel surface is smooth, there is not the stimulation to the human body during the use, consequently can adopt silica gel to make. When the medical staff uses the existing inflatable laryngeal mask, the laryngeal mask needs to be inflated according to experience, so that the laryngeal mask is attached to the cavity wall of the laryngeal cavity, the laryngeal mask is prone to bursting due to excessive inflation, or the inflated laryngeal mask can leak air, so that the laryngeal mask cannot be attached to the cavity of a human body. The laryngeal mask integrally formed by using the silica gel has the advantages that the step of inflation can be omitted, the time for inserting the laryngeal mask is saved, the rescue time can be strived for patients, and meanwhile, the laryngeal mask cannot be attached to the wall of the laryngeal cavity due to air leakage of the laryngeal mask can be avoided.

Referring to fig. 1, a barrier 12 is disposed between the first opening 22 and the second opening 23 for blocking the backflow of vomitus. The patient end of the cover body part 21 is a round tip, the cover body part 21 has good elasticity, is not easy to kink and can resist compression, and the round tip is arranged at the patient end of the cover body part 21 to guide the patient end of the laryngeal cover to pass through a narrow body cavity more easily.

Referring to fig. 3, the camera 31 is disposed in the camera channel 34 and is retracted from the machine end of the camera channel 34 relative to the patient end face of the camera channel 34, and the closest distance to the patient end face of the camera channel 34 is kept between 0.2mm and 1mm, so that the camera 31 is not exposed outside the laryngeal mask, thereby preventing the hard camera 31 from touching the body lumen and ensuring the clear picture. A flushing channel 35 is provided in the inner wall of the tube body 1 and the mask body portion 21 adjacent to the camera channel 34, the flushing channel 35 is provided with a flushing hole 36 facing the camera 31 and communicating with the camera channel 34, and the flushing hole 36 is located at the patient end side of the camera 31. The camera channel 34 and the flushing channel 35 are separated by 1-3mm, and the flushing channel 35 is bent 50-80 degrees at a position close to the patient end face of the camera channel 34 and points to the camera 31 to form an inclined flushing hole 36 for flushing the camera 31. To achieve a flushing effect, the flushing hole 36 is located at the front end of the flushing channel 35, substantially flush with the camera head 31. The outside of the tube body 1 is connected with a flushing channel 35, and a flushing pipe and a flushing joint (not shown) are arranged, when sundries in front of the camera 31 block shooting, medical staff can utilize flushing equipment such as a syringe and the like to be connected with the flushing joint, and the sundries in front of the camera 31 can be flushed away by injecting air or liquid. The method is simple and ingenious, has good washing effect, and can effectively reduce the pain of patients.

Referring to fig. 2, a spring 4 capable of matching with the inner wall of the tube body 1 is arranged in the tube body 1, and the spring 4 is wound in the inner wall of the tube body 1, so that the phenomenon that the tube body 1 is unsmooth in ventilation due to the fact that the tube body 1 is folded to form an angle under stress is avoided by utilizing the characteristics that the spring 4 is good in elasticity, not prone to being twisted and capable of bearing pressure, and medical accidents are reduced.
