Specific embodiment

Below with reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear Chu is fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole realities Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art are not under the premise of making creativity labour All other embodiment obtained, belongs to the range of the protection of the utility model.

As shown in Figs. 1-5, a kind of noninvasive decompression mask further includes short including cover 1, the bracket being arranged on the inside of cover 2 Pipe 11, the bracket 2 are two parts, and respectively bracket a3 and the one end bracket b4, the bracket a3 are connected on annulus 6, another End is connected to one end on bracket b4, and the bracket a3 and bracket b4 connect and compose umbrella shape and can strut cover 1；The short tube 11 Short slab 12 is arranged in end, and short tube 11 is fixedly connected in annulus 6 by short slab 12 and can be around the arbitrarily movement of annulus 6, the short tube Unidirectional device 5 is arranged in 11 inside；Bandage 8 is arranged on 7 both sides of fixed plate for mounting plate 7 on 6 side of annulus.

Preferably, the bracket a3 diameter is greater than bracket b4 diameter.

Preferably, the bracket a3 is equipped with several apertures 9 spaced apart, and protruding part 10 is arranged on bracket b4, described The embeddable aperture 9 of protruding part 10.

Preferably, the bandage 8 is equipped with velcro.

Preferably, the bracket a3 and bracket b4 is arc and respectively four.

Preferably, two outlet apertures 13 are set on the cover 1.

Preferably, hydrocolloid coating 14 is arranged close to facing side in the cover 1.

Preferably, the unidirectional device 5 is in splayed configuration.

Preferably, 6 inner ring of annulus is that have notch 15, and short slab 12 is stuck in notch 15.

Preferably, protrusion 16 is arranged close to 13 position of outlet aperture in the cover 1, and the protrusion 16 is equipped with velcro.

Embodiment one:

The bracket b4 of arc is pulled outwardly so that protruding part 10 thereon is embedded in the aperture 9 of bracket a3, will form one A umbellate form covers on cover 1 on umbellate form at this time and umbellate form is equally presented, the hydrocolloid coating 14 on cover 1 can close to face, with This is simultaneously fixed the bandage 8 in fixed plate 7 around head circumference by velcro, and then hydrocolloid coating 14 is maintained tightly to touch Face, then oxygen is entered in mask by short tube 11, due to being provided with the unidirectional device 5 of splayed configuration in short tube 11, therefore oxygen Gas can only enter mask by unidirectional device 5, and without flowing backwards, what the gas of characteristics of contaminated respiratory droplets was merely able to be arranged from cover 1 goes out Gas aperture 13 is discharged.

Embodiment two:

The inside retraction of bracket b4 is equally (specific by the cooperation between protruding part 10 and aperture 9 in bracket a3 Are as follows: when external force inwardly pushes away bracket b4 along bracket a3, protruding part 10 can be embedded into aperture 9, and bracket b4 can contract at this time Enter and be overlapped a part in bracket a3 a part), with the size of overlapping, the umbellate form that decide that bracket b4 and bracket a3 is constituted is big The size that small i.e. cover 1 is softened, and the size that cover 1 is softened can be and be useful in nose, snout or entire face, One multi-purpose stacking mask.

Above description is only a specific implementation of the present invention, but the protection scope of utility model is not limited to This, anyone skilled in the art within the technical scope disclosed by the utility model, the variation that can readily occur in or is replaced It changes, should all cover within the protection scope of utility model.
