Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 and 2 all shows according to the framework 10 for breathing mask of the present utility model and the corrugated hose 20 for this breathing mask.Wherein, this breathing mask can be connected with respirator, to be supplied to wearer breathing the respirable gas exported that picks.
As shown in Figure 1, this framework 10 comprises fastening cover 2.Fasten cover 2 and comprise buckling end 2a and link 2b corresponding thereto, and be configured in the variant part 5 between buckling end 2a and link 2b.In fastening cover 2, variant part 5 can be made up of flexible material, and other parts can be made up of hard material.Described flexible material can be rubber or silica gel; And hard material can be the alloy material of resin or lighter weight.In addition, the various piece fastening cover 2 also can be made up of flexible material.
Buckling end 2a, for installing the liner (not shown) of breathing mask, is provided with the fixed structure 201 for installing this liner at the buckling end 2a fastening cover 2.Fixed structure 201 is chosen as can the structure of clamping liner, is preferably looped around the annular flange flange on the outer wall of the buckling end 2a fastening cover 2.Thus, this liner just can be fixed by annular flange flange after being set to the buckling end 2a fastening cover 2.Fasten cover 2 and join wearer's mouth and/or nose to by this liner, to accept the gas from respirator.Wherein, described liner belongs to well known to those skilled in the art, and no further details to be given herein.
This link 2b has through hole 202 (see Fig. 3), and it is applicable to the corrugated hose 20 connecting breathing mask.Corrugated hose 20 rotatably can be connected to from through hole 202 and fasten cover 2, wearer can be adjusted be connected to the orientation residing for corrugated hose 20 fastening cover 2, thus is convenient to wearer and changes posture, such as, change into from lying low and lie on one's side.Wherein, corrugated hose 20 is chosen as bend pipe or straight tube.In addition, corrugated hose 20 is removably connected to this link 2b, to facilitate, corrugated hose 20 is pulled down cleaning.In other embodiments, corrugated hose 20 also can be arranged to unremovably be connected to this link 2b.
In a preferred embodiment, fasten cover 2 and also comprise the annular fold 8 (see Fig. 3) be looped around outside through hole.Annular fold 8 can be avoided occurring gap between mask body and patient facial region while wearer or other people suitably pull corrugated hose, thus avoids leaking air herein.
According to this utility model, this framework 10 comprises being fixedly installed on and fastens on cover 2 and the forehead support frame 3 be between link 2b and variant part 5.Forehead support frame 3 is preferably made up of resin material.In a preferred embodiment, forehead support frame 3 and the one-body molded design of fastening cover 2, to be easy to simplify production technology.This forehead support frame 3 can comprise the fixed cover 3a being located at and fastening on cover 2.Fixed cover 3a form fit formula can be enclosed within the front end of fastening cover 2 and is fixed in the groove of the outer wall fastening cover 2.
In addition, this forehead support frame 3 also can comprise and against the subsides frontal plate 3b of wearer's forehead, and can be connected the engagement plate 3c of fixed cover 3a and subsides frontal plate 3b.This subsides frontal plate 3b can be the arc suitable with human body forehead, more comfortable to make when pasting when frontal plate 3b is fitted in human body forehead.Wherein, be respectively equipped with the first connector 301 in the both sides of fixed cover 3a, and be also respectively equipped with the second connector 302 in the both sides of pasting frontal plate 3b.First connector 301 and the second connector 302 are all preferably hook formation, for the headband fast, removably installing breathing mask.In addition, the first connector 301 and the second connector 302 also can be configured to the circulus closed.Wherein, described headband also belongs to well known to those skilled in the art, does not repeat them here.
This variant part 5 can be configured to corrugated tube shape, zigzag, along fasten cover 2 the curved distribution of outer wall recess or along the convex shape of the curved distribution of outer wall fastening cover 2, certain those skilled in the art also can be configured to other shape according to real needs.When wearer wears the breathing mask employing this framework 10, this variant part 5 can after fastening cover 2 joins wearer's mouth and/or nose to liner, make forehead support frame 3 fit in the forehead of the wearer of different forehead height by himself distortion, thus realize the object of adjustment forehead support frame 3 automatically.
In addition, the active force of part from headband can be shared by forehead support frame 3 according to the framework 10 for breathing mask of the present utility model, thus reduce the active force that headband is applied to fastening cover 2 and liner, therefore effectively can alleviate the constriction being applied to wearer's face by fastening cover 2 by liner.Meanwhile, according to the framework 10 for breathing mask of the present utility model compared to the existing framework for breathing mask, especially disclosed in Chinese patent CN101472637A, forehead supports has simple structure more, can reduce manufacturing process and manufacturing cost.
In one embodiment, variant part 5 comprises one or more fold 501, and this fold 501 all can be configured to from fastening the top of cover 2 along both sides to the fold of downward-extension, and the fold to downward-extension can surround and fasten the whole circle of cover 2, also only can extend to the sidewall fastening cover 2.When wearer wears in the process of breathing mask, forehead support frame 3 can be allowed backwards or forward to swing, to be suitable for the wearer of different forehead height by the mode of the opening reducing or expand the fold 501 fastening cover 2.In addition, variant part 5 also can be configured to the fold from fastening the bottom of cover 2 and upwards extending along both sides, can also allow forehead support frame 3 to swing backwards or forward by the mode reduced or expand its opening thus.
Consider that the ability to bear of nasal region will be weaker than mouth region, preferably fold 501 is configured to from fastening the top of cover 2 along both sides to downward-extension, so more be beneficial to wearer swing in the process of forehead support frame 3 reduce wearer's nose bear dynamics, thus improve or eliminate the discomfort that wearer's nasal region occurs.
In a preferred embodiment, this variant part 5 is chosen to a fold 501.This fold 501 is limited with opening towards the U-shaped of outside or inside or the depression 501a of V-arrangement that fasten cover 2, and namely longitudinal section view is the depression of U-shaped or V-arrangement.Select the depression 501a of this U-shaped or V-arrangement to be more convenient to manufacture compared to the depression 501a of other shape, its Deformation Demands can be met well simultaneously.
In another preferred embodiment, the opening (L shown in Fig. 3 can illustrate the position of this opening) of depression 501a can be sized to successively decrease gradually to the direction bottom it along from the top fastening cover 2, be convenient to like this reduce processing technique and manufacturing cost as much as possible while meeting its Deformation Demands.
In summary, forehead support frame 3 can automatically be adjusted, with the wearer making it be applicable to different forehead height according to the framework 10 for breathing mask of the present utility model.
Although be described this utility model with reference to preferred embodiment, when not departing from scope of the present utility model, various improvement can be carried out to it and parts wherein can be replaced with equivalent.Especially, only otherwise there is structural hazard, the every technical characteristic mentioned in each embodiment all can combine in any way.This utility model is not limited to specific embodiment disclosed in literary composition, but comprises all technical schemes fallen in the scope of claim.
