During use, gas-pressurized advances in first group of air induction conduit 74 by adapter 90 inputs of flow generator adapter 84 and by second group of air induction conduit 76, enters into two side frame member 32 of framework 16 again.Gas enters the base part 48 and the mouth of pipe 50 by framework 16, is input to patient's nasal passage 12 then.Can discharge by the steam vent 78 that is located at the framework 16 from patient's nose expellant gas.

Headgear assemblies 20 is detachably connected on second link 26 that is connected with framework 16 so that framework 16 and mouth of pipe assembly 18 can remain on the desired position of adjusting in patient face.As shown in figure 18, headgear assemblies 20 comprises two lateral parts 92, makes aft section 94 connect this lateral parts 92.Each lateral parts 92 comprises side band 96.The aft section 94 that is connected with two lateral parts 92 comprise cross the patient crown on 98 with walk around the back of patient's back of head and be with 100.But headgear assemblies can be fixedly connected on the framework.

Each side band 96 is detachably connected on second link 26.Specifically, each side band 96 end has the width that reduces, the cross bar 70 that makes this side band 96 can reel and be arranged on second link 26.This side band 96 is fastened on and can adopts hook and annular material on each cross bar 70, as Velcro .Thereby side band 96 can carry out accommodation with respect to second link 26.

On with 98 and after be detachably connected on the side band 96 by the bracelet 102 that is arranged on the side band 96 with 100.These bracelet 102 useful binders, stitching and/or other known modes are bonded on the side band 96.In example embodiment, bracelet 102 comprise single cross bar so that on be with 98 and after be with 100 to combine.But, can adopt any other Fastener structure that is fit to make to be with 98 and after be with 100 to interconnect with side band 96.

Headgear assemblies 20 be with 96,98 and 100 can make with soft and flexible composite.For example, can comprise one deck of constituting by textile material with 96,98 and 100 and the two layers of material of another layer of constituting by polymer.In addition, headgear assemblies 20 can comprise one or more rigid members that are connected thereto with the rigidity in specific plane and direction increase headgear assemblies, and nasal assembly 10 is stabilized in patient head when helping to use.

In addition, headgear assemblies 20 can comprise that multi-ribbon is to support nasal assembly 10 in patient head.For example, shown in Figure 11 and 12, each bar side band 96 can comprise a pair of band that is used for second link 26.Perhaps, headgear assemblies 20 can be made into the structure of one.

As shown in Figure 1, base part 48 stretches out so that extra surface area or bottom area to be provided from framework 16.When the air admission framework 16 of pressurized, base part 48 inflation, it moves the mouth of pipe 50 and makes itself and patient's nasal passage 12 sealed engagement.For example, base part 48 makes the mouth of pipe move and patient's nasal passage 12 sealed engagement along the expansion of nostril direction.

In addition, a part of sealing force can be provided by the first 56 of the nostril prestrain of withstanding patient as spring.

That is to say that the base part of this structure 48 is expansible and shrink to change the distance between the framework 16 and the mouth of pipe 50.Base part 48 make the mouth of pipe 50 the close primary importance of the mouth of pipe 50 and patient's nasal passage 12 and the mouth of pipe 50 moves and the second position of patient's nasal passage 12 sealed engagement between move.Specifically, under the situation of unaerated, the mouth of pipe 50 is separated with patient's nasal passage 12 or is slightly contacted.When nasal assembly 10 was subjected to gas pressure, base part 48 inflation and the mobile mouth of pipe 50 made itself and patient's nasal passage 12 sealed engagement, thereby made that formation seals between nasal assembly 10 and patient's the nasal passage.Along with air pressure increases, the power that is added to the nasal cavity downside increases by base part 48.

Base part 48 provides extra surface area or bottom area for framework 16, its correspondingly line up 50 provide extra power to increase the leakage efficiency of the mouth of pipe 50.That is, base part 48 settings and location so that the mouth of pipe 50 contact with patient's nose.Power on patient's nose or pressure and: (a) pressure in framework 16 and the mouth of pipe assembly 18; (b) extra surface area on the base part 48; And/or (c) from the mouth of pipe 50 or base part 48, comprise the center wall 54 and the first 56 of base part 48, material and the preloading that forms of geometry proportional.Thereby the surface area of base part 48 can change, and for example, is added to power or pressure on patient's nose with change.

The sidewall 52 of base part 48 can be used as spring structure to provide component by the mouth of pipe 50 in patient face.This power can be carried out adapt by the thickness of adjusting sidewall 52.In addition, the thickness of sidewall 52 can change in conjunction with the additional surface that base part 48 provides is long-pending.Thereby the power that base part 48 provides provides effective sealing force with patient's nasal passage 12 with air pressure.

Base part 48 makes the tension force that is suitably sealed needed headgear assemblies reduce.That is, the sealing force that is added to patient's nose can be provided by base part 48, preloading and/or air pressure, rather than is provided by the tension force of headgear assemblies 20.This improves patient's comfort level and sealing characteristics.

Therefore, when adjusting headgear assemblies 20, it is desirable to make the mouth of pipe 50 only near or with patient's very slight the contacting of nose.By this way, base part 48 reality pressurized not.Do not need during use fully to contact and seal.

Base part 48 also provides the decoupling joint between the framework 16 and the mouth of pipe 50, thereby allows motion relatively between nasal assembly 10 and the patient face.As a result, the mouth of pipe 50 can adapt to the various little variation of patient's nose shape facility and not produce unsuitable power, and can solve the little motion of nasal assembly 10 with respect to patient's nose in use, and the sealing of remaining valid.

In addition, coupling assembling 22 comprises first and second links 24,26, makes the position of the mouth of pipe 50 be easy to the nose adjustment with respect to patient.Specifically, patient can make framework 16 rotate to adjust the position of the mouth of pipe 50 with respect to headgear assemblies 20.

In addition, base part 48 needs not to be above-mentioned single pedestal form, and can have other structure.For example, base part 48 can be two and more forms of the base parts of arrangement according to the order of sequence.

As illustrated in Figures 5 and 6, the end of base part 48 is in certain angle so that the mouth of pipe that is connected thereto 50 is in certain angle.This angle also can be referred to as wing angle, is adjustable to adapt to difform patient's nose.For example, mouth of pipe assembly as illustrated in Figures 5 and 6 has scope at 135-155 ° wing angle, preferably at about 145 °, to adapt to flat substantially nose (seeing Figure 19).Perhaps, the scope at wing angle can be at 70-90 °, preferably at about 80 °, to adapt to basic point or precipitous nose (seeing Figure 20).But this wing angle can have any suitable national size to adapt to the nose of Any shape.The mouth of pipe mobile helps to be fit to steeper nose.

As shown in figure 21, the seal area of the mouth of pipe 50 can extend with an angle from the only about half of height of the mouth of pipe.In example embodiment, the height of the mouth of pipe 50 is about 9mm.But the mouth of pipe 50 can have any suitable height and any suitable seal district can be provided.(if wish that deletion Figure 21 please advise from this application.)

The mouth of pipe 50 suitably separates on base part 48 each other.The distance that separates is based on the size of the mouth of pipe 50 and the free space of base part 48.

The size of the mouth of pipe 50 is based on the girth in patient nostril.In one embodiment, ellipse ratio can be used for determining the geometry (seeing Figure 22) of the mouth of pipe.For example, ellipse ratio 0.7 (meansigma methods+1 standard deviation) can be used for determining the geometry of the mouth of pipe.As shown in figure 23, the basic main shaft of the mouth of pipe 50 can be determined by the distance of measuring center, nostril and upper lip.As shown in figure 24, the basic minor axis of the mouth of pipe 50 can be determined by availability interval maximum between the mouth of pipe.But, can adopt any other method that is fit to determine the size of the mouth of pipe.(if wish that deleting Figure 22-24 from this application please advise.)

The interval between above-mentioned wing angle, seal area, the mouth of pipe and the size of the mouth of pipe can be determined to be applicable to various patients.And, the nasal assembly of different size can be provided, for example, trumpet, medium size, large size is to adapt to the patients of various different sizes.But, can adopt any other method and mode so that the patient's who is fit to maximum magnitude nasal assembly to be provided.

An aspect of of the present present invention relates to a kind of sealing and isolating nasal assembly of stability force of making.That is, nasal assembly has this structure, and the sealing force that make to keep nasal assembly seal between the stability force of patient face and maintenance nasal assembly and patient's face is separated or differentiated at least better.During use, sealing force acts on the more responsive zone of patient face, and as nose, and stability force acts on the not too responsive zone of patient face, as the rear portion of upper lip, buccal and patient's head.And stability force is tending towards greater than sealing force.Thereby nasal assembly is configured to make bigger stability force to separate substantially to improve patient's comfort level with less sealing force.

Specifically, the structure of nasal assembly can make the added stability force of headgear assemblies be distributed to rear portion, patient's the buccal of patient's head and patient's upper lip to remain on nasal assembly patient's face in use.This nasal assembly applies the mouth of pipe assembly of sealing force to patient's nasal passage when comprising use.The feature of headband makes sealing and stability force to adjust substantially respectively.Thereby higher stability force can similarly not influence the more sensitive zone of patient face, as nose etc.

Another aspect of the present invention relates to the mouth of pipe and applies force to contact between the base part of patient face.Specifically, base part is configured to add component and becomes to add component to patient face to patient face and nozzle construction.

As shown in Figure 1, for example, base part can have abundant hard structure so that it adds relatively little component to patient face, that is to say that base part can not expand or expand by gas pressurized the time substantially.On the contrary, the mouth of pipe can have flexible structure so that it can provide relatively large component to patient face.That is, the first 56 of the mouth of pipe 50 can be used as a spring structure, and for example, spring loads or elasticity, with by the mouth of pipe 50 in the patient face power of plusing fifteen.To load by spring, to mean the purpose in order sealing, the mouth of pipe adds a predetermined power and arrives patient's nasal cavity sealing area.As preferably, the mouth of pipe is thought that by prestrain the user provides sealing force before the input gas-pressurized.As a result, the base part and the mouth of pipe provide power together so that seal between nasal assembly and patient's the nasal passage.

Perhaps, base part can have flexible structure, makes it apply big relatively component patient on the face when expanding.On the contrary, the mouth of pipe can have more inflexible structure, makes it apply relatively little component patient on the face.As a result, the base part and the mouth of pipe provide power together so that seal between nasal assembly and patient's the nasal passage.

Therefore, the structure of mouth of pipe assembly can be used for sealing to apply enough component so that the mouth of pipe is spring loaded or has elastic force.Thereby base part can have harder structure to apply less component for sealing.Perhaps, mouth of pipe assembly can be configured such that base part can fully expand with add enough component in order to the sealing, and the mouth of pipe can have harder structure with add less component in order to the sealing.Perhaps, the mouth of pipe can be a substantially rigid, for example, and under the situation for concrete customization.These changes can with formerly embodiment in conjunction with (relevant rigid base partly and spring-loaded (as prestrain) mouth of pipe).In this case, the structure of the base of the mouth of pipe can provide variable pre-load amount, and the hermetic unit of the mouth of pipe, is preferably customization, can be harder relatively.And the structure of this mouth of pipe assembly can make the base part and the mouth of pipe provide similar substantially component to supply sealing.
