Example 1

Air cover is prevented to noninvasive ventilator, in order to avoid air intake of air cover 1, influence the treatment, the inventor has set up mouth cover 11, and set up silica gel frame 12, as a preferred embodiment, as shown in fig. 2 fig. 3 and fig. 4, including air cover 1, one side of air cover 1 is provided with air outlet sleeve 2, air outlet sleeve 2's top is connected with fixed strip 3, opening 10 has been seted up to one side center department of air cover 1, opening 10's inboard is connected with mouth cover 11, annular 110 has been seted up in mouth cover 11's the outside, one side of mouth cover 11 is equipped with boss 111, through-hole 112 has been seted up to boss 111's top side symmetry, the inboard edge of air cover 1 bonds there is silica gel frame 12.

In this embodiment, the air hood 1 is made of cotton cloth, and is comfortable when contacting with skin, and the mouth sleeve 11 and the silica gel frame 12 are made of silica gel integrally, and are soft when being attached to the periphery of the mouth and the face, so that the air hood is good in sealing performance, and air cannot enter.

Specifically, the mouth sleeve 11 is an oval tubular structure, more fits the mouth shape, covers the mouth for only give vent to anger, no department admits air, annular groove 110 and opening 10 joint cooperation, and bond with sealed glue, through-hole 112 runs through boss 111, and the elastic band 13 has been sewed up to the both sides of gas hood 1, is convenient for hang and wear behind the ear.

Example 2

As the second embodiment of the utility model, in order to avoid the vapor condensation to soak the gas hood 1, the inventor has improved the cover 2 of giving vent to anger, and set up fixed strip 3, as an preferred embodiment, as shown in fig. 1, fig. 5, fig. 6 and fig. 7, the one end center department of the cover 2 of giving vent to anger has seted up cavity 20, heavy platform 21 has been seted up to the inboard bottom of cavity 20, the bottom surface center department of heavy platform 21 is equipped with card post 22, the terminal surface of the cover 2 of giving vent to anger just is located cavity 20's the outside and has seted up recess 23, the outside of recess 23 just is located the side symmetry of the cover 2 of giving vent to anger and has seted up perforation 24, a plurality of air outlet groove 25 have been seted up to heavy platform 21's inboard, the bottom surface symmetry of fixed strip 3 is equipped with inserted column 30, the top surface of fixed strip 3 is.

In this embodiment, it is integrative to go out gas jacket 2 and fixed strip 3 and all adopt the PP material promptly polypropylene to make, and its matter is light, toughness is good and intensity is stiff for wear merrily and lightheartedly, durable.

Specifically, the air outlet sleeve 2 is in an elliptic cylinder structure, the size of the sinking platform 21 is larger than that of the cavity 20, the outer side of the clamping column 22 is clamped with a silica gel sheet 220, the clamping column 22 is clamped with a central circular hole of the silica gel sheet 220, the size of the silica gel sheet 220 is equal to that of the sinking platform 21, the silica gel sheet 220 is positioned at the rear side of the air outlet groove 25, i.e. far away from the bottom of the sinking platform 21, when the patient gives off air, the air flow pushes the silicon sheet 220 to turn upwards, so that the silicon sheet 220 has space to turn, and then the air is discharged from the air outlet groove 25, since the silica gel sheet 220 is made of silica gel, it has flexibility and sealing property, and after the air flow of the air-out disappears, it will immediately recover to block the cavity 20, if the patient carelessly inhales air from the mouth, the silicone sheet 220 will be blocked by the plug 30 and will not be depressed, so that the airflow can not enter, and the patient can only inhale from the nostrils, thereby continuously receiving the treatment of the noninvasive ventilator.
