[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1-4 The embodiment of the utility model provides a technical solution: a mask for a ventilator, comprising a mask portion 1 and a limiting portion 2 connected thereto; the main body of the mask portion 1 is a mask shell 11 that is sleeved on the outside of the user's nose and mouth, the front side of the mask shell 11 is fixedly connected to an trachea 12, a gas diffuser 13 is fixedly installed in the trachea 12, the output end of the trachea 12 is fixedly connected to a flow guide 15 located on the inner side of the mask shell 11, the output end of the flow guide 15 is fixedly connected to two sets of nasal tubes 16 positioned opposite each other, and the bottom side of the mask shell 11 is provided with an exhaust slot 17 connected to the outside air;

[0027] Among them, the mask for the ventilator can ensure its air supply effect through the setting of two sets of nasal tubes 16 in the mask part 1. Combined with the setting of it probing into the user's nasal cavity, it can prevent the reflux of carbon dioxide exhaled by the patient from affecting the operation of the ventilator. At the same time, the setting of three sets of outward-stretched handles 14 and straps 22 can ensure the pulling effect of the three sets of outward-stretched straps 22 and ensure stability when worn. At the same time, the brain pad 21 can provide overall protection for the back of the user's head from the back, increase the user's comfort, and solve the problems of poor air supply effect, poor wearing stability and limited comfort of the existing device.

[0028] Example 2:

[0029] The nasal tube 16 is an upwardly inclined hose portion, and the outer end of the nasal tube 16 extends into the user's nasal cavity; wherein, the setting of the nasal tube 16 enables the trachea 12 on the front side of the mask shell 11 to transmit gas directly from it to the user's nasal cavity, ensuring that the gas inhaled by the user is the gas input by the trachea 12, avoiding the situation where oxygen reflux causes the ventilator to work poorly.

[0030] A silicone gasket is fixedly installed on the outer edge of the mask shell 11 and contacts the user's skin; wherein, the setting of the silicone gasket can increase the sealing performance when worn, and also ensure the comfort of the user when worn.

[0031] A handle 14 is fixedly connected to the center of the top and the two corners of the bottom side of the head pad 21, and a perforation is opened at the outer end of the handle 14; wherein, the handle 14 and the perforation are arranged to facilitate the hooking of three sets of straps 22 to meet the needs of different users.

[0032] The main body of the limiting part 2 is a brain pad 21 attached to the back of the user's head. Straps 22 are fixedly connected to the center of the top and the two corners of the bottom side of the brain pad 21, and the three groups of straps 22 are hooked into the three groups of handles 14 on the mask shell 11; among them, the hook-mounted arrangement of the straps 22 and the handles 14 can pull and limit the mask shell 11 from three directions, ensuring the stability of the mask part 1 when it is affected by the limiting part 2 when worn.

[0033] The main body of the binding strap 22 is an elastic band, and the outer end of the elastic band is fixedly connected with a folded Velcro.

[0034] The working principle and usage process of the present invention are as follows: when the device is needed to work, the mask part 1 is put on the front side of the user's mouth and nose, and the brain pad 21 in the limiting part 2 is covered on the back of the user's head from the back side. Finally, three groups of straps 22 are used to hook the three groups of handles 14 to ensure the wearing effect and comfort. At the same time, the nasal tubes 16 are slightly inserted into the patient's nasal cavity to ensure the air supply effect.
