面罩和其组成部件 Mask and component parts thereof

技术领域 FIELD

本发明一般涉及用于非侵入性正压供气装置(NIPPA)、连续气管正压力装置(CPAP)和供气装置的整个脸部面罩。 The present invention relates generally to non-invasive positive pressure supply means (NIPPA), continuous positive airway pressure device across the face mask (CPAP) and an air supply means.

背景技术 Background technique

将正压可呼吸气体从供气装置输送到患者需要在机器和患者之间的某种界面。 The pressure of breathable gas from the supply means to the patient in need of some kind of an interface between the machine and the patient. 通常采用放在气管内的管作侵入性供气的患者界面。 Usually placed endotracheal tube for supply of invasive patient interface. 在非侵入性供气时,采用某种形式的面罩作患者的界面。 When non-invasive gas, some form of the mask as the patient interface.

面罩通常包括一个室,该室具有由外壳或者框架形成的接收鼻子的空腔。 The mask generally comprises a chamber, the chamber having a nose receiving cavity formed by the housing or the frame. 该面罩通常还包括可舒适接触面部的部分,例如软垫,该软垫固定于外壳或者框架的边缘。 The mask portion may also typically includes comfortable contact face, e.g. cushion, the cushion is fixed to the edge of the housing or frame. 面罩通常用头戴具,例如一组弹性带,固定在患者面部的适当位置。 Usually wearing a mask with, for example, a set of elastic bands, fixed in position in the patient's face. 改进面罩的舒适度,特别是在面罩需要戴若干小时时,一直是对面罩设计人员的挑战。 Improved face mask comfort, especially in the need to wear a mask for several hours, it has been a challenge for mask designers.

除非对各个使用人定制面罩,因为面形很不相同,所以面罩的大部分装置是一种折中设计。 Unless custom mask for each use, because surface shape very different, so that most of the mask means is a compromise design. 一种面罩设计可能很配合一小部分患者群的鼻子形状(例如高鼻梁骨),但是对具有不同形状鼻子(例如矮鼻梁骨)的另一部分人群就不能很好配合。 Towards a mask designed with the shape of the nose might be a small portion of the patient population (e.g., high nose bone), but another portion of the population having a different shape of the nose (e.g. short nasal bone) can not be fit well. 设计一种面罩来很好地密封鼻梁部分是特别困难的,因为面部的该区域是特别容易感受的。 To design a good seal nose mask portion is particularly difficult because the surface area is particularly easy to feel.

在面罩软垫上的折皱,在长期戴用时,可能会使患者的面部很不舒服。 In wrinkles on the face mask cushion, in the long-term wear, it may cause the patient's face uncomfortable. 另外尽管使用软垫,仍然能够通过软垫感受到面罩框架的边缘,对着患者的面部形成不舒服的表面,特别是软垫受到压缩时。 Although additional cushion, still be able to feel the edge of the mask frame by a cushion, facing the face of the patient uncomfortable formed surfaces, particularly when subjected to compression cushion.

在一些情况下,面罩适合包括通气孔隙,这种排气孔隙除其他许多东西而外,允许受控的漏气流出面罩,以便防止在面罩内积存CO2。 In some cases, the mask comprises a suitable ventilation apertures, which apertures inter exhaust many other things out, to allow a controlled outflow of mask leak, to prevent the accumulation of CO2 within the mask. 例如,在面罩和患者皮肤之间的结合部,也存在疏忽的或者无意的面罩漏气。 For example, between the mask and the binding portion of the patient's skin, there is inadvertent or unintentional mask leak. 采用形成低或者零无意漏气的面罩可以改进供气装置特别是响应呼吸气流信号的供气装置中高级控制算法的操作。 Formed using low or zero unintentional leak supply means mask can be improved in particular in response to operation of the air supply means algorithm senior respiratory flow control signal.

在睡觉期间,患者可能会动。 During sleep, the patient may move. 另外,由于例如肿胀,在睡觉期间患者头部的形状可能改变。 Further, since the swelling example, may change the shape of the patient's head during sleep. 尽管在开始配接时面罩很贴合患者,但是因为夜间的这种动,面罩随后贴合便不太好。 Although the mask is fitting the patient at the beginning of mating, but at night because of this dynamic, face mask and then it is not a good fit. 现有技术面罩通常包括弹性头戴具带,这些带可以缩短或者伸长,或者可以重新配置在头部上,使面罩回到舒适的漏气小的位置。 Prior art masks typically comprise an elastic band with a headset, which can be shortened or elongated strip, or may be reconfigured on the head, the mask for the comfort of a small leak location.

在治疗期间可以改变由供气装置提供的维持压力。 It can be varied during the treatment to maintain pressure provided by the air supply means. 一些连续的气管正压力(CPAP)装置形成一种从低压到治疗压力的初始斜坡。 Some continuous positive airway pressure (CPAP) apparatus to form a ramp from low to initial treatment pressure. 其他CPAP装置可以按照气流范围的指示,自动调节压力。 Other CPAP device can follow the instructions airflow range, automatically adjust the pressure. 其他装置可以在患者的呼吸周期内改变维持压力,例如在吸入时提供较高的维持压力,而在呼出时,提供较低的维持压力。 Other means may be varied within the patient's respiratory cycle to maintain the pressure, such as providing a higher pressure is maintained in the suction, while the outgoing call, to provide a lower pressure is maintained. 弹性头戴具带必须配置成适合于这种维持压力。 The elastic band must be configured with the headset is adapted to maintain this pressure. 如果弹性带配置成适合高压力,则有这样的危险,即弹性带在低压力时,绷得太紧而不舒服。 If the elastic band is configured for high pressures, there is a danger that the elastic bands at low pressure, stretched too tight and not comfortable.


本发明的一方面,是提供一种用于非侵入性供气装置的舒适的漏气低的面罩,该面罩可以克服现有技术面罩的局限性。 In one aspect of the present invention, a low leakage comfortable mask provides a non-invasive means for gas supply, the mask may overcome the limitations of the prior art mask.

在另一方面,希望提供一种面罩系统,该系统具有一个或多个以下的特征,其中各个特征有助于改进患者的顺从性和/或治疗:头戴具,包括基本上不能伸缩和/或可以微调的带;和/或面罩和/或软垫,这些面罩和/或软垫包括各种部件,以便增强/改进密封,和/或贴合患者面部的选出位置。 In another aspect, it is desirable to provide a mask system that has one or more of the following features, each of which features contribute to improved patient compliance and / or treatment of: wearing a tool, comprising substantially not stretching and / or may trim the tape; and / or mask and / or cushion, these masks, and / or cushion includes various components to enhance / improve the sealing and / or bonding the selected position of the patient's face.

框架组件70包括具有一个或多个横向部件100的底盘95(在图3中清楚示出)。 The frame assembly 70 includes a one or more transverse chassis 95 (best shown in FIG. 3) of the member 100. 该横向部件100支承悬臂延伸部件90,该延伸部件又连接于前后向带25的前端55。 The cantilever support member 100 transversely extending members 90 which in turn extends to the longitudinal member 25 to the front end of the belt 55 is connected. 该前后向带25的前端55具有螺纹部件105,该螺纹部分穿过延伸部件90形成的接收孔91,如图1和2清楚示出的。 The front has a distal end 55 to the tape 25 is threaded member 105, the threaded portion extends through the receiving hole 90 formed in member 91, as shown in FIG. 1 and 2 clearly shown. 螺母110可以在螺纹部分105上转动,从而可以调节延伸部件90和患者前额50之间的距离。 Nut 110 can be rotated on the threaded portion 105, which can adjust the distance between the members 90 and 50 extend the patient's forehead. 因此,可以细调带的张力,特别是在前后向带25如上所述,用基本上不能伸缩的材料制作时。 Accordingly, fine tune the tension of the belt, when made with the material substantially not stretchable band 25 as described above especially around.

图3示出面罩组件10的前视图。 Figure 3 shows a front view of the mask assembly 10. 从图3中可以看到,底盘95包括许多从底盘95伸出的指形部件115。 As can be seen in FIG. 3, the chassis 95 includes a plurality of projecting fingers 95 from the chassis member 115. 在底盘95各个侧面上的最下指形部件115包括孔120,该孔构造成为可以接收从水平带30各个端伸出的螺纹部件105。 On each side of the chassis 95 of the lowermost finger member 115 includes an aperture 120, the aperture may be configured to receive a threaded member 30 from the horizontal with the respective projecting ends 105. 螺母110可以用螺纹固定于螺纹部分105,使得可以细调面罩组件15和患者面部之间的距离。 Nut 110 can be screwed to the threaded portion 105, making it possible to fine-tune the distance between the mask assembly 15 and the patient's face. 因此,这些条可以以很高的准确度拉紧,使得在给定的约2到40cm水柱高的压力范围内,作用在面部的力恰如其分。 Thus, the strips can be tightened with high accuracy, so that within a given about 2 to 40cm of water pressure in the high range, the force of the face appropriately.

如图3和4清楚示出的,该螺纹部分105基本上为长方形横截面,包括两个相当平的侧面和具有螺纹部分的两个侧面。 3 and 4 clearly shown, the threaded portion 105 is substantially rectangular in cross-section, comprising two relatively flat sides and two sides with a threaded portion. 孔91和120的形状与螺纹部分105的形状是互补的。 Shape 91 and the threaded hole 120 of portion 105 are complementary. 例如,孔91和102具有大体长方形形状,由此在调节螺母110时,可以防止螺纹部分转动。 For example, the holes 91 and 102 has a generally rectangular shape, whereby when the adjusting nut 110, the threaded portion can be prevented from rotating. 虽然未示出,但是螺纹部分105的端部也包括具有长方形孔的部件,从而有助于防止螺纹部分105的转动。 Although not shown, the end of the threaded portion 105 also includes a rectangular member having a hole, to help prevent rotation of the threaded portion 105.

图4是侧视图,更清楚示出各个水平带30和框架组件70之间的连接。 FIG 4 is a side view more clearly show the connection between the respective horizontal band 70 and a frame assembly 30. 另外,图4示出,各个指形部分115可活动地例如可转动地连接于底盘95的横向部分96和97。 Further, FIG. 4 shows the respective finger portion 115 may be movable, for example, is rotatably connected to the chassis 95 of the lateral portions 96 and 97. 在此特殊例子中,顶部两个指形部分115连接于横杆125,而底部的两个指形部分115连接于类似的横杆130。 In this particular example, the top two finger portions 115 is connected to the crossbar 125 and the two fingers is connected to the bottom portion 115 of rail 130 similar. 因此,在底盘各个侧面上的两个顶部指形件和两个底部指形件分别可以协调一致地运动,从力的分布观点看这是有利的。 Thus, two on each side of the top chassis and two bottom fingers are fingers can be coordinated movement, from the viewpoint of the force distribution of view this is advantageous. 然而应当考虑到,各个指形件相对于底盘95的横向部件96和97可以独立活动。 It should however be taken into account, the respective fingers 96 relative to the transverse chassis members 95 and 97 may be independent activities.

在此实施例中,从各个水平带30端部31伸出的螺纹部分105穿过形成在下部两个指形部分115上形成的接收孔120。 In this embodiment, a threaded portion 31 extending through the receiving holes 105 formed in a lower portion of the two finger portions 115,120 are formed from the respective horizontal band end portion 30. 这样,当拧紧螺母110时,将会张紧在水平带30上的任何松弛。 Thus, when the nut 110 is tightened, the tension will be in the horizontal strip 30 on any slack. 当张紧所有的松弛以后,螺母110的进一步拧紧将会导致右手侧下部两个指形部分115相对于软垫支承件80顺时针方向转动(从上面观看)。 When all the tension relaxation after tightening nut 110 is screwed further will result in a lower part of the right-hand side of the two fingers 115 with respect to the cushion support member 80 is rotated clockwise (viewed from above). 左手侧下部两个部分,在从上面观看时将反时针方向转动。 The left-hand side of the lower two portions in rotation counter-clockwise as viewed from above. 软垫支承件80在至少靠近指形部分115的侧部分82是可形变的。 Cushion support member 80 at least near the side portion 115 of the finger portion 82 is deformable. 由于这种形变,该侧部分82可以向软垫75中的相应部分施加力,从而压紧患者鼻子的两侧。 Due to this deformation, the side portion 82 may apply a force to the respective cushion portion 75, thereby compressing the sides of the patient's nose.

如图4所示,软垫75与柔性的或者可形变的软垫支承件80可以通过例如指形件115形成一体,从而更好匹配各种脸面的轮廓。 4, the cushion 75 and the flexible or deformable cushion support member 80 may be integrally formed by, for example, the fingers 115, to better match the contour of the various face. 在制造很软和极软软垫支承件之间需要折中,很软是为了更好地贴合面部,极软造成面罩内部体积随每次吸气过分改变(例如大于20毫升)这使得测量潮流体积很困难。 The tradeoff between manufacturing very soft and very soft pad supports, very soft in order to better fit the face, resulting in a very soft interior volume of the mask changed over with each inhalation (e.g., greater than 20 ml) which makes measurements current volume is very difficult. 约1-3mm厚度的常规硅橡胶是合适的。 Conventional silicone rubber thickness is about 1-3mm suitable.

图5是后视图,示出面罩组件15,在此组件中,在患者面部左侧的上部两个指形部分115可以手推压在软垫支承件80的一个侧部分82上。 FIG 5 is a rear view showing the mask assembly 15, in this assembly, the upper portion of the left side of the patient's face two finger portions 115 can push against the upper side of a support member 80 of the cushion portion 82. 上部两个指形部分115作用于软垫侧部分82的力可以使软垫75发生形变,使得它可以推压鼻子的侧面,由此可以接纳不同形状的鼻子,并增强软垫75的密封性能。 Two upper finger portion 115 the force acting on the cushion side portion 82 of the cushion 75 can be deformed so that it can be pressed against the side of the nose, thereby receiving the nose of various shapes, and to enhance sealing performance cushions 75 .

在图1-5中,带的张力和支承件80的两个侧边82的可形变性一起可以使指形件转动并同时推压,由此可以挤压鼻子的两侧和一部分患者脸面。 In Figure 1-5, the belt tension and the support deformability two side edges 82 of the can 80 with the fingers and rotates while pushing, thereby squeezing both sides of the nose and the face portion of the patient. 因此,利用独立的转动性可以适配形状不规则的脸面。 Thus, use of an independent rotation of irregular shape can be adapted to the face. 这也有助于将作用力均匀分配在脸面上,由此松开高接触力的区域。 This also contributes to uniform distribution of the force on the face, whereby the areas of high contact force release.

图5示出增加顶部条(未示出)张力的结果,张力的这种增加导致压迫患者的鼻梁区域。 FIG. 5 shows the results (not shown) to increase tension top bar, this increase results in tension compression nasal bridge region of the patient. 对于双压力的治疗,这是特别有用的,使得在低压力下,只作用很低的力,而在高压下,作用高的力,这有助于改进舒适程度和密封。 For the dual treatment pressure, which is particularly useful, such that at low pressure, low force acting only, and under high pressure, high force, which helps to improve comfort and sealing. 用非弹性材料制造头戴具,有助于防止面罩在脸面上的“活塞作用”,即,在双压力治疗期间,在高压时升离面部和/或在低压时进入面部。 With non-wearing resilient material, it helps prevent the "piston effect" of the mask on the face, i.e., during the two-pressure treatment, when the high pressure lift off the face and / or into the surface at low pressures.

在图1-5所示的实施例中,形成在底盘95各个横向部分96和97上的两个上部指形部分图中表示为连接于头戴组件20的任一带部件上。 In the embodiment illustrated in Figure 1-5, the chassis 95 is formed in an upper finger portion of each of two lateral portions 96 on FIG. 97 and shown connected to a headset on either assembly 20 along the member. 然而,这种上部带部分的定位可以如图2中想象线135和140所示。 However, this positioning of the upper belt section 2 may be an imaginary line in FIG. 135 and 140 shown in FIG. 具体是,想象线135表示上部带部分连接于冠面带35中部的状态。 Specifically, the imaginary line 135 represents a portion connected with an upper face with a central crown of a state 35. 想象线140表示上部带部分在头戴具各侧连接于水平带30的状态。 Each portion having a state of wearing a belt 30 side is connected to the horizontal imaginary line 140 represents the upper belt.

2.第二实施例图5A和5B示出本发明的另一实施例,在此实施例中,水平带30包括第一连接部分C1,该连接部分可选择性地连接于第二连接部分C2。 2. Second Embodiment FIGS. 5A and 5B show another embodiment of the present invention, in the embodiment, the horizontal band 30 comprises a first connecting portion C1 in this embodiment, the connecting portion is selectively connected to the second connection portion C2 . 该第二连接部分C2固定于下部带LS和上部带US。 The second connecting portion C2 is fixed to the upper belt and the lower belt LS US. 上部和下部带LS、US可以张紧到它们紧压在框架70横向部分82的程度,由此可以在软垫75上施加向内的力,从而在侧面密封患者鼻子的两侧。 The upper and lower belt LS, US tensioned they can be pressed against the lateral extent of portion 82 of frame 70, whereby an inward force may be exerted on the cushion 75, so that both the side of the sealing patient's nose. 该上部和下部带LS和US可调地固定于框架70(如箭头所示),从而可以更好地定位向内力作用的区域。 The upper and lower belt US LS and adjustably fixed to the frame 70 (as shown by arrows), so as to better locate the region of the internal forces. 在此实施例中,支承件80的侧部分82用可形变材料制作,而顶点是更刚性的。 Embodiment, the side portion 82 of the support member 80 may be made with a deformable material In this embodiment, the apex is more rigid.

3.第三实施例图5C-5H示出本发明的再一实施例,在此实施例中,调节机构可以粗调和细调头部带的张力。 3. Third Embodiment FIGS. 5C-5H shows a further embodiment of the present invention embodiment, in this embodiment, the adjustment mechanism may be coarse and fine head band tension. 图5C示出整个面罩组件,该组件包括面罩框架800,该框架具有肘管805,该肘管包括防窒息的阀门810。 5C shows the entire mask assembly includes a mask frame 800, the frame having elbow 805 includes an anti-asphyxia valve 810 of the elbow. 配置快速松开扣件815,以便患者可以很性地取下头戴具,如2002年9月6号提出的美国专利申请No.10/235846所述,该专利申请整个作为参考文献包含在本文中。 Configuring quick release fastener 815, so that the patient can be removed wearing of tools, as described in US Patent No. 6 September 2002 made Application No.10 / 235,846 said, as throughout this patent application incorporated herein by reference in. 图5D示出处于局部打开位置的快速松开机构,而图5E示出完全打开的快速松开机构。 5D shows a quick-release mechanism in a partially open position, and FIG. 5E shows a quick-release mechanism is completely open.

带820包括用于将面罩组件保持在患者头部的一对带端部820A和820B。 With a mask assembly 820 includes means for maintaining the patient's head with a pair of end portions 820A and 820B. 其中一个带端部例如820B可以通过例如槽821连接于位于固定位置的面罩框架的一端,由此可以避免带820的长度变化,在重复的取下或者重新放上面罩组件时,可能发生这种长度变化。 Wherein a strap end portion 820B by, for example, an end of the slot 821, for example, attached to the mask frame in a fixed position, whereby to avoid change in length of tape 820 is removed when repeated or re-placed mask assembly, which may occur changes in length. 另一带端部820A配置和构造成为可调的。 The other end portion 820A with the configuration and construction become adjustable. 当然,带820的两个端部均是可调的。 Of course, the two ends of the belt 820 are adjustable. 弯曲带820,使带端部820B穿过槽821,形成一个可用铆钉822或者其他紧固件固定的环。 Curved belt 820, the belt end portion 820B passes through the slot 821, can be used to form a rivet 822 or other fastener ring.

可以配置调节组件825来调节带820。 Adjustment assembly 825 may be configured to adjust the belt 820. 具体是,如图5F所示,该调节组件包括大体长方形的棱柱体830,该棱柱体具有穿过其整个长度的带接收槽835。 Specifically, as shown in FIG. 5F, the adjustment assembly comprises a generally rectangular prism 830, the prism 835 has a belt receiving groove through its entire length. 该槽具有显示在棱柱体端面上的开口840。 The groove 840 having a display opening in the end face of the prism. 该棱柱体具有上部分836、下部分837和螺杆845,如图5G清楚示出的。 The prism 836 has an upper portion, lower portion 837 and a screw 845, shown clearly in FIG. 5G. 该上部分和下部分836和837可以采取适合于粗调带长度的第一位置,在此位置可以将带端部820A拉过槽835的长度。 The upper and lower portions 836 and 837 may be adapted to take a first position with coarse length, in this position with the end portion 820A may be pulled through the length of the slot 835. 在适合于细调的第二位置,该上部分和下部分836、837将结合在一起,使得螺杆845与带端部820A接触,从而防止带通过槽835。 In the second position suitable for fine adjustment of the upper and lower portions 836,837 will be combined so that the screw 845 into contact with the end portion 820A, thereby preventing the band through the slot 835. 螺杆845在转动时,将使带端部820A移动,从而张紧或者放松头戴具。 Screw 845 is rotated, will move with the end portion 820A, so that the tensioning or relaxing with headgear. 该上部分和下部分836、837通过槽和销钉部件841、842可以平移,从而使螺杆845移动,达到或者脱离与槽835的接触。 The upper and lower portions 836,837 can translate through the slots 841 and 842 and the pin member, so that the screw 845 is moved to reach or out of contact with the groove 835. 该螺杆845具有一个伸过棱柱体835长度的具有第一齿轮部分850的端部。 Having a screw 845 extending through the end portion 850 of the gear 835 has a first length prism. 如图5H所示,第一齿轮部分850又以直角接合第二齿轮部分855。 As shown in FIG 5H, the first gear portion 850 again engages the second gear portion 855 at right angles. 第二齿轮部分855具有固定在上面的圆柱钮860。 The second gear portion 855 has a cylindrical knob 860 fixed thereto. 转动该圆柱钮860便可以转动第二齿轮部分855,由此驱动第一齿轮部分850,因而驱动螺杆845。 Rotating the cylindrical knob 860 can rotate the second gear portion 855, thereby driving the first gear portion 850, and therefore the drive screw 845. 取决于转动方向,带或者拉出或者推入该槽,由此可以细调带的长度。 Depending on the direction of rotation, with or pushed in or pulled out of the groove, whereby the fine tune the length of the belt.

C.充气胆-气包和枕骨气动垫1.第一实施例参考图1,图中示出头戴组件20,图中示出包括特殊形状的充气胆,这种胆将称为沿例如头戴组件20前后向带25配置的“气包”145。 C. inflatable bladder - and occipital pneumatic cushion air bag 1. First Example Embodiment Referring to FIG 1, the headgear assembly shown in FIG. 20, there is shown the inflatable bladder comprises a special shape, which will be referred to in the bile head e.g. wear assembly 20 to the belt 25 disposed before and after the "air bag" 145. 该气包145配置成可以在面罩压力的整个范围内将相对恒定的带力作用在患者的面部。 The air bag 145 is disposed so as to be in full mask pressure will be relatively constant with a force acting on the patient's face. 该气包145是一种活性部件,可以用气体作功,从而在较高压下,将面罩牵引到面部。 The air bag 145 is an active member, the gas may be used as the work, so that a high pressure, pulling the mask to the face. 气包145通过小直径的硅胶管150与面罩中的压力相通,该硅胶管接在面罩组件15上的或者靠近该组件的气体出入口上。 Air bag 145 through a small-diameter silica tube 150 in communication with the pressure in the mask, the silicon tube connected to the mask assembly 15 on or near the gas entrance of the assembly. 在此例中,该管850配置在肘管845上,前后向带25上的带张力至少通过气包145由气源压力局部形成,该张力在较高压力下可以使带更加张紧/更多位移,而在较低压力下可以使带不太张紧/或者更小位移。 In this embodiment, the tube 850 is arranged on the elbow 845, the belt tension before and after the belt 25 by the air bag 145 at least partially formed by the air pressure, the tension in the belt at a higher pressure may be more tension / more multi displacement, while at lower pressure may make with less tension / displacement or less.

虽然将气包145表示为优选实施例,但是可以采用其他机构得到带张力/位移的变化,这些机构包括电动系统和机械系统。 While the air bag 145 is the preferred embodiment represented, but others may be obtained with a tension change / displacement using these bodies for electrical and mechanical systems. 当面罩压力增加时,气包压力增加使气包充气到更像球形,由此使它前后缩短,因而将向后的牵引力作用在悬臂90上,由此使面罩更可靠地压在面部上。 When the mask pressure increases, air bag pressure is increased to make the air bag inflated like a spherical, thereby making the front and rear shortened, and therefore the rearward traction force on the boom 90, thereby to more reliably press the mask on the face.

作为第一级近似,由气包或者悬臂90产生的方向向后的力正比于面罩压力。 As a first approximation, the boom 90 by the air bag or the direction of rearward force generated is proportional to the mask pressure. 在螺母110拧紧时,其比例常数较大,使得在一定面罩压力下,该气包可以更容易拉长。 When tightening the nut 110, which is a larger proportional constant, so that at a certain mask pressure, the air bag can be more easily stretched. 因此,气包145可以看作为一种自动补偿机构,如果这样调节该机构,使得在一个压力下,面罩密封,则面罩将在所有压力下密封,并将一直平衡面罩中的空气压力。 Thus, the air bag 145 can be seen as an automatic compensation mechanism, the adjusting mechanism if so, at such a pressure, seal the mask, the mask will be sealed at all pressures, and will always balance the air pressure in the mask.

压力增加ΔP时,气包将膨胀ΔV,由此做功ΔVΔP,由此反抗力的作用,将悬臂90上的连接点91向后拉一段距离。 When the pressure increase [Delta] P, [Delta] V air bag will expand, thereby acting ΔVΔP, whereby the resistance force, the connection point on the boom 90 91 pulled back some distance.

虽然只在顶部带上形成气包145,但是也可以在其余的带包括水平带30上形成另外的气包。 Although only belt to form a gas bag 145 at the top, but may further be formed on the air bag 30 with the remaining tape comprises a horizontal. 然而在此实施例中,在下部带上没有加上任何气包145,因为患者下颚和下唇部的自然走向形成波浪形,这种情况在一定程度上近似于包145的作用,从而在整个操作压力范围内,在该区域中形成良好的运动。 However, in this embodiment, the lower portion of tape without adding any air bag 145, as natural to a patient and a lower jaw lip formed wavy, in this case to a certain extent similar to the role of the package 145 so that the entire within the operating pressure range, a good movement in the region. 换言之,面罩顶部的密封机构和面罩底总后密封机构是不同的。 In other words, the sealing means and the top of the mask substrate mask GLD sealing mechanism is different. 对于面罩底部,面罩设计人员可以依靠患者的下唇部和下颚来加压,而在面罩的顶部,采用不同的机构,因为鼻梁区域的面部结构是骨头的,很硬。 For the bottom of the mask, the mask designers can rely on the patient's jaw and lip pressure in the top of the mask, using different means, since the structure of the nasal bridge region of the face is bone, very hard.

2.气包的细节已在一般意义上说明气包145,下面参看图6-15A进行说明,这些说明更详细说明了气包的更具体原理。 2. Details of the air bag has been explained in the general sense air bag 145, will be described below with reference to FIG. 6-15A, described in more detail these more specific principle of the air bag.

气包145是橡胶例如硅橡胶作的长方体薄壁管,可以沿两个侧面折皱起来,然后在非折皱的端部封闭起来。 Air bag 145 is rubber such as silicone rubber rectangular thin-walled tubes together along two side folds can then closed up in a non-bellows end portion. 将非折皱的封闭端部插入到面罩组件15的头带例如前后向带25中。 The non-crumpled portion of the closed end 15 is inserted into the mask assembly with headgear 25, for example, forward and backward. 图6和7示出气包145处于松弛状态,其中基本上没有压力或者完全没有压力,例如在患者呼气期间,而图8和9示出在治疗压力下例如在患者吸气期间的气包145。 6 and 7 show the air bag 145 in a relaxed state, wherein substantially no pressure or no pressure, such as during patient exhalation, while Figures 8 and 9 show, for example during the patient inspiratory air bag 145 at the treatment pressure . 对于双气压供气装置,患者在吸气期间曝露于相对较高的压力,而在呼气期间曝露于较低的压力,将气包145充气到压力p将使气包145缩短或者变宽,因此头部带25将被拉得更紧。 For dual pressure air supply means, exposed to the patient during inspiration relatively high pressure, while during expiration exposed to lower pressure, the air bag 145 is inflated to a pressure p air bag 145 will widen or shorten, Thus the head band 25 will be pulled tighter.

下面假定气包145在纵向是松弛的,而在横向是刚性的,使得它可以在所有压力下可以保持上述平顶横向部分。 Next, assume that air bag 145 is slack in the longitudinal direction, but is rigid in the transverse direction, so that it can be flattened portion of said lateral holding at all pressures. 在制造时,可以通过例如将刚性杆横向粘接在顶表面和底表面上,或者将顶表面和底表面模制成具有横向脊条,和/或在左右可伸缩壁之间用内部系丝,来取得这种平顶横向部分。 In manufacturing, it can have a transverse ridges, and / or wire line between the left and right internal walls of the telescopic rod by a rigid transverse side bonding for example on the top and bottom surfaces, or the top and bottom surfaces made of mold to obtain such a flat top transverse portion. 实际上,基本概念和以下说明是不用这些精细加工来得到大致的放松。 Indeed, the basic concepts and the following description are obtained without these fine processing to substantially relax.

在图10的例子中,气包145具有宽度W和充气高度2h。 In the example of FIG. 10, the air bag inflator 145 has a width W and a height of 2h. 可伸缩的侧面被假定为施加忽略不计的力,并且不包含在计算中。 Retractable side is assumed to be negligible force is not applied to the meter, and is not included in the calculation. 带上的力是f。 Belt force is f. 在图10中,气包145被横向切成两半,一对刚性板固定于该切线,其中一个刚性板用编号155表示。 In Figure 10, the air bag 145 is transversely cut in half, a pair of rigid plates fixed to the tangent, wherein a rigid plate with reference numeral 155. 由刚性杆160连接这两个板。 A rigid rod connecting the two plates 160. 在刚性杆160上的力也是f。 Force on the rigid bar 160 is f.

假定顶部带上轴向表面张力(力/单位长度)是t。 Assumed axial top belt surface tension (force / unit length) is t. 因为组件不随时间变动,所以作用在可见板155上的力其合力必须为零。 Because the component does not change with time, the plate 155 acts on the visible resultant force which must be zero. 这些力包括作用在左边的力2tW、作用在右边的力2pWh和作用在右边刚性杆160上的力f:2tW=f+2pWh (1)如果对于p>0,在带上不存在任何表面张力,则气包145的顶表面和下表面将一起形成圆柱体(θ=π/2)。 These forces include force 2TW on the left, the force acting on the right and 2pWh force f acting on the right side of the rigid bar 160: 2tW = f + 2pWh (1) If the surface tension for any p> 0, in the absence of tape , the top surface of the air bag and the lower surface 145 will form a cylinder (θ = π / 2) together. 当带25在受到张力作用时,表面将变成两个半径为r的圆柱体的不完全对称扇形,如图11的横截面所示。 When subjected to tension the belt 25, the surface of the cylinder into two radius r of the fan is not completely symmetrical cross-section 11 as shown in FIG.

两个表面与带的相交线位于平衡状态,即其上没有作用任何净力。 The line of intersection of two surfaces of the belt is located in a state of equilibrium, i.e. no effect on any net force. 因为超出连接点的气包145的表面是不相关的,所以可以用半径为r的其余圆柱体替换超过连接点的整体。 Since the surface beyond the point of attachment of the air bag 145 is not relevant, it may be replaced with a cylinder of radius remaining integrally connected over the point r.

[0093]顶部或者底部表面的横截面是圆弧,其半径为r,并且对着圆心的角为2θ。 [0093] The cross section of the top or bottom surface of a circular arc having a radius r, and angle toward the center of 2θ.

根据简单的几何图形,在气包145顶表面或者底表面和带的延伸线之间的角度也是θ,如图12所示。 The simple geometry, the angle between the surface of the air bag 145 or the extension line and the bottom surface of the belt is [theta], as shown in Fig. 因为在连接部分的净作用力为零,所以我们得到:f=2Wt cos(θ) (2) Because zero net force of the connecting portion, so we get: f = 2Wt cos (θ) (2)

[0095]从图12可以明显看出,另一个约束方程是:h=r(1-cos(θ)) (3) [0095] As apparent from FIG. 12, another constraint equation is: h = r (1-cos (θ)) (3)

最后,如果气包145具有拉平长度L(带之间的距离),则圆弧的周长为:L=2rθ (4)因此有四个连立方程,五个未知数p、h、t、f和θ,和两个常数W和L。 Finally, (the distance between the belt), if the length L of the air bag 145 has a flattened, the circumferential length of the circular arc: L = 2rθ (4) therefore even four simultaneous equations, five unknowns p, h, t, f and θ, and two constants W and L. f的解为:f=pWLcos(θ)/θ (0<θ<π/2) (5) Solutions of f is: f = pWLcos (θ) / θ (0 <θ <π / 2) (5)

[0097]注意以下的特性:(i)如果气包是拉平的,即θ→0,则任何正压力将产生无限大的力;(ii)如果θ=π/2,即气包为圆柱形,则f对于所有的p为零。 [0097] Note the following characteristics: (i) if the air bag is flattened, i.e., θ → 0, then any positive pressure force generated infinite; (ii) if θ = π / 2, i.e., a cylindrical air bag , then f is zero for all p. 忽略掉伸缩侧面的特性,W和L在力的产生中起同样作用。 Ignored side telescopic features, W and L in the same function of the force produced. 二者之一加倍将使力加倍。 Doubling the force will either be doubled.

[0098]产生的力随气包145的长度变化。 [0098] The force generated with the gas bag 145 changes in length. 从图11可以看出,气包两端的距离x由以下方程确定:x=2rsin(θ) (6)替换方程式(4)中的r可以得到:x=Lsin(θ)/θ (7)再注意到:f=pWLcos(θ)/θ (5)用上面方程列出表1。 As can be seen from FIG. 11, the distance x across the air bag is determined by the following equation: x = 2rsin (θ) (6) alternatively the equation r (4) can be obtained: x = Lsin (θ) / θ (7) and then note: f = pWLcos (θ) / θ (5) are listed in table 1 using the above equation. 表1的第二行示出对各种角度θ的作为固定长度L百分数的气包长度“x”(见图11)。 The second row of Table 1 is shown as a percentage of a fixed length L of the various angles θ of the air bag length "x" (see FIG. 11). 第三行表示产生的力“f”(见图10),该力表示为压力p、宽度W和固定长度L乘积的百分数。 The third row represents the force "f" (see FIG. 10), expressed as a percentage of the force of the pressure p, the width W and the length L of the product is fixed.

表1 Table 1

图13画出力f(表示为pLW的百分数)随长度x(表示为固定长度L的百分数)变化的函数曲线。 13 shown in FIG force f (expressed as a percentage of pLW) with the length x (expressed as a percentage of a fixed length L) is a function curve.

对θ角微分方程(5)和(7)得到:df/d=-pWL[sin(θ)/θ+cos(θ)/θ2] (5a)dx/dθ=L[cos(θ)/θ-sin(θ)/θ2] (7a)用(7a)除(5a)(对于0<θ=π/2)得到:df/dx=pW[cos(θ)/θ+sin(θ)]/[sin(θ)/θ-cos(θ)] (8a)在θ→0的极限(空的气包)中,分母变为1,而分子变为无限大,所以弹簧具有无限大的正刚度。 Angle [theta] of the differential equation (5) (7) and obtained: df / d = -pWL [sin (θ) / θ + cos (θ) / θ2] (5a) dx / dθ = L [cos (θ) / θ -sin (θ) / θ2] (7a) with (7a) except (. 5A) (for 0 <θ = π / 2) to give: df / dx = pW [cos (θ) / θ + sin (θ)] / [sin (θ) / θ-cos (θ)] (8a) in the θ → limit (empty air bag) is 0, the denominator becomes 1, and the molecule becomes infinite, so infinite spring having positive stiffness . 对于完全允气的气包(θ=π/4),刚度为正4pw/π)。 Allowed for complete air bag gas (θ = π / 4), the positive stiffness 4pw / π). 表2加上了前一表的刚度。 Table 2 together with the rigidity of the front of a table.

表2 Table 2

例子实际的气包具有:W=5cm=0.05m;L=6cm=0.06m;p=20cmH2O=1960N/m2~2000N/m2。 An air bag having a practical example: W = 5cm = 0.05m; L = 6cm = 0.06m; p = 20cmH2O = 1960N / m2 ~ 2000N / m2.

如果气包145是局部充气的,并保持在两个刚性支承件之间,则带的张力随压力线性增加。 If the air bag 145 is partially inflated, and held between two rigid supports, the belt tension increases linearly with pressure.

对于任何给定的几何形状,产生的力正比于气包的固定长度和外延。 For any given geometry, proportional to the force and extension of the fixed length of the air bag.

对于任何给定的压力,在气包位于其静止长度时,所产生的力为无穷大,然后很快下降。 For any given pressure, when the air bag is in its resting length, the force generated is infinite, then decreased rapidly.

作为一个例子,连接于20cmH2O压力的6cm长×5cm宽度的气包在缩短0.5cm时,产生约0.633kgf的力,在缩短1.0cm时,产生约0.300kgf的力,缩短1.5cm时,产生约138g的力。 As one example, is connected to a pressure 20cmH2O 6cm long × 5cm width of the air bag is shortened 0.5cm, a force of about 0.633kgf, when retracted 1.0cm, a force of about 0.300kgf, is shortened 1.5cm, generate about 138g of force.

这种力对长度有很强的依赖关系的结果是,用螺钉拉紧头带将使得在给定压力下,可以产生任何要求的力。 This force is the result of the length dependence has a strong, the screw will tighten the headband such that at a given pressure, the force may be produced in any desired.

面罩组件15利用两个带25和30保持在面部的三个点上。 Mask assembly 15 with two bands 25 and 30 are held at three points of the face. 将面罩组件15构造成为底边为12cm和高度为12cm的等腰三角形,去掉在高度为2cm和底边2cm的底部棱角中形成较小的两个三角形。 The mask assembly 15 is configured as a base and a height of 12cm to 12cm of the isosceles triangle, is removed at a height of two triangles formed smaller 2cm 2cm and bottom edges of the bottom. 因此,面罩的总面积为70cm2。 Thus, the total area of ​​the mask was 70cm2.

在20cmH2O的压力下,空气压力将施加1400g的力,而在5cmH2O压力下,将施加仅350g的力。 20cmH2O under pressure, the air pressure force applied 1400g, and 5cmH2O under pressure, applying a force of only 350g. 可以假设,为了进行密封,需要施加比此力高30%的力,或者施加1820g的力。 May be assumed, for sealing, a force needs to be applied than 30% of the force, or the force applied to 1820g.

参考图15,假定1)矩心C位于面罩底部上面4.5cm的位置,或者位于顶部下面的7.5cm的位置;2)底部带连接于面罩底部上面约3.5cm的位置,或者在矩心下面1cm的地方固定;3)顶部带在矩心的上面约15cm处连接于一根长杆。 Referring to Figure 15, assume that a) the centroid position of the mask C is 4.5cm above the bottom, or at a position below the top of 7.5cm; 2) with a bottom connected to a position of about 3.5cm above the bottom of the mask, in the following centroid or 1cm a fixed place; 3 above) in the centroid of the top belt at about 15cm is connected to a pole.

因为底部带的连接比顶部带的连接约15倍靠近矩心,所以底部带承受负载的15/16,只留下100g的力由顶部带支承。 Because the bottom than the top belt is connected with a connecting centroid close to about 15 times, so the bottom of the belt to withstand the load of 15/16, leaving only 100g of force supported by the top belt.

在顶部带上有6cm长×5cm宽的气包。 At the top belt with a 6cm long × 5cm wide air bag. 该气包用管子105连接于面罩。 The air bag 105 is connected with a pipe to the mask. 在其长度减小到4.35cm时,该气包在20cmH2O压力下将产生100g的力。 When the length is reduced to 4.35cm, the air bag at 20cmH2O pressure generated force of 100g. 在此长度和压力下,气包的刚度为0.232kg力/cm。 Under this pressure the length and stiffness of the air bag forces 0.232kg / cm.

假定气包145与弹回率为ESTRAP的可伸长的头戴具带串联。 And air bag 145 is assumed rebound rate ESTRAP extensible belt having a series of wearing. 可伸长的袋和气包的自由端部是固定的。 The free end portion of the package may be an elongated gas bag is fixed. 总系统的弹回率将使头戴具的弹回率加上气包的弹回率。 Bounce rate of the overall system will bounce rate plus wearing a gas bag with bounce rate.

例如,假定5cm宽×6cm长的气包与弹回率为10cm/kgf的好洗的传统ResMed头带串联安装。 For example, assume 5cm wide × 6cm long recoil air bag and was 10cm / kgf good wash ResMed conventional headgear mounted in series. 气包在20cmH2O压力时,为4.35cm长,并施加0.1kg的力,如前所述。 20cmH2O air bag when the pressure of 4.35cm length, and applying a force of 0.1kg, as described above.

在这种条件下,气包的弹簧常数为0.232kgf/cm,所以其弹回率为4.3cm/kg。 In this condition, the spring constant of the air bag was 0.232kgf / cm, so the spring back was 4.3cm / kg. 因此总的系统其(局部)弹回率为14.3cm/kg。 Therefore, the total system which (partial) recoil was 14.3cm / kg. 整个系统的弹回率由传统带控制。 Rebound rate of the system with conventional control.

作为另一例子,从5cm宽×6cm长的气包出发,压力为20cmH2O。 As another example, from 5cm wide × 6cm long air bag starting pressure 20cmH2O. 因此,长度仍为x0=4.35cm,产生的力f0=100g。 Therefore, the length remains x0 = 4.35cm, the force generated by f0 = 100g. 该气包仍然与弹回率为0.1kg/cm的带,即弹簧常数Kstrap=10kg/cm的带串联,下一步是确定在压力降低到5cmH2O时发生的事情。 The air bag is still playing back and was 0.1kg / cm band, i.e., the spring constant Kstrap = 10kg / cm connected in series with, the next step is to determine what happens when reduced pressure 5cmH2O.

由可伸长带产生的力与气包长度x的关系方程是:fstrap=f0-Kstrap(x-x0)将这一关系画在由气包在20cmH2O和5cmH2O压力产生力的图上,我们得到图15A。 By a force generated by the elongation of the relational equation with the air bag length is x: fstrap = f0-Kstrap (x-x0) painted on the relationship between the air bag by the forces generated 20cmH2O and FIG 5cmH2O pressure, we obtain Figure 15A.

头戴具将收缩,使得气包从4.35cm伸长到约4.8cm,并且带的张力不是按要求从0.1kg减小到0.05kg的,而是降低到仅约0.55kg。 Wearing tool will shrink, so that the air bag from the elongated 4.35cm to about 4.8cm, and the belt tension is not required to be reduced from 0.1kg 0.05kg, but is reduced to only about 0.55kg.

在没有气包时,由鼻梁支承的不需要的带张力为75g。 In the absence of the air bag, supported by a nose with unnecessary tension 75g. 用基本上不能伸缩的或者刚性的头带时,正确调节的气包通常可以将此力降到零。 When not using a substantially rigid or telescopic headband, correct adjustment of this air bag may generally be reduced to zero force. 但对于很深的头带,不需要的带张力为45g,或者是不用气包时的一半多一点。 But for deep headband, belt tension is unnecessary 45g, or not more than half the time of the air bag point.

(转动连接件470的第一和第二位置分别示于图24和25)。 (A first and a second position rotatable connecting member 470 are shown in FIGS. 24 and 25). 这样,便可以调节杆450的相对角位置。 Thus, you can adjust the relative angular position of the lever 450. 沿螺纹杆移动螺母468,可以准确调节框架436和头戴具414上的张力。 Movement of the nut along the threaded rod 468, the frame 436 can be adjusted accurately and with the tension in the headset 414. 这种配置也形成快速松开装置。 This configuration also form quick release apparatus. 因为框架436包括软的底部分438和顶部分442,所以在调节它们,寻找对患者更适合的配合时,框架将按照螺母468在杆450上的位置进行弯曲。 Because the frame 436 includes a bottom portion 438 and the soft top portion 442, so that the adjustment thereof, is more suitable for the patient to find a fit, the frame 468 is bent according to the position of the nut on the rod 450.

可充气的枕骨气垫416与带456、458、460形成传力关系,并且在操作上定位在带组件452的下面和头部的后面,一般位于枕骨区域。 Inflatable occipital cushion 416 is formed with a force transmitting relationship with 456,458,460, and is positioned below and behind the head strap assembly 452 in operation, the occipital region generally located. 该枕骨气垫可以充气和放气。 The occipital cushion can be inflated and deflated. 在一个实施例中,如图23所示,该枕骨气垫416通过管子414连接于面罩组件412的送气管462。 In one embodiment, 23, the occipital cushion 416 by a tube attached to the mask assembly 414 of the snorkel 462 412. 这样,枕骨气垫416中的气压与面罩组件412中的气压相同。 Thus, the same air pressure in the occipital cushion 412 and 416 in the pressure mask assembly. 当面罩组件412的压力增加时,该枕骨气垫416便充气,这导致头戴具张力同时增加,并防止面罩组件412脱离面部,而发生漏气。 When the mask assembly 412 of the pressure increase, then the inflatable occipital cushion 416, which leads to tension and increase wearing tool, and prevents the face from the mask assembly 412, and the leak occurred. 这样便可以在不同面罩压力期间,缓冲面罩组件412的移动。 This makes it possible during different mask pressure, movement of the mask assembly 412 of the buffer.

枕骨气垫416被设计成具有足够大的面积(Abladder),使得在与枕骨气垫中416中的空气压力(Pbladder)结合时,该气垫将抵消头作用在戴具带456、458、460上的作用力(即由面罩组件412中压力造成的作用在袋456、458、460上的力)。 Occipital cushion 416 is designed to have a sufficiently large area (Abladder), such that when combined with the occipital cushion air pressure of 416 (Pbladder), which will offset the head cushion with belt wear acting role 456,458,460 force (i.e., caused by the action of the pressure force on the mask assembly 412 456,458,460 of the bag). 一般说来,枕骨气垫416的面积应当作得相当大,以便提供一个力,该力超过面罩引起的力,该力是面罩设计面积(Amask)和面罩压力(Pmask)的乘积。 Generally, occipital cushion area 416 should be made relatively large, so as to provide a force which exceeds the force caused by the mask, the mask layout area is the product of a force (AMASK), and mask pressure (PMASK) a. 因此:Abladder×Pbladder=∑加在带上的力另外,Abladder×Pbladder>Amask×Pmask在一种优选形式中,该枕骨气垫416约为11cm×16cm,其壁厚在约1.5mm-2.5mm之间,总的放气厚度为3-5mm。 Thus: Abladder × Pbladder = Σ Further force applied on the belt, Abladder × Pbladder> Amask × Pmask In one preferred form, the occipital cushion 416 is approximately 11cm × 16cm, a wall thickness of about 1.5mm-2.5mm , with a total thickness of the discharge gas 3-5mm.

在上述实施例中,在枕骨气垫416中的压力随面罩压力增加而增加。 In the above embodiment, the pressure cushion 416 along with occipital mask pressure increases. 然而,在本发明的其他实施例中,可以利用除面罩压力外的参数控制枕骨气垫416的充气和放气。 However, in other embodiments of the present invention can be controlled occipital cushion 416 inflated and deflated using the parameters except the mask pressure. 例如,传感器可以检测面罩组件412中的漏气,方法是,例如连续检测连接于面罩组件412和低通过滤器的气源中的流量,以便找到气流的泄漏量。 For example, the sensor may detect leaks mask assembly 412, is, for example, continuous flow detection mask assembly is connected to the gas source 412 and a low pass filter in order to find the amount of leakage gas flow. 当确定漏气很大时,将使枕骨气动垫416充气。 When determining a large leak, it will occipital pneumatic inflatable cushion 416. 相反,当漏气被确定为比较低时,可以使枕骨气动垫放气。 Conversely, when gas leakage is determined to be relatively low, the pneumatic cushion can be made occipital deflated. 用漏气检测传感器控制枕骨气动垫416的压力,可以使戴具414保持在最小的张力量,这种张力量也可以面罩具412保持对面部的密封,并有助于减轻使用人的不舒服、皮肤受损和过度张紧头戴具固有的其他问题。 Leak detection with a pneumatic pressure sensor 416 to control the occipital pad 414 can be made with wear at a minimum amount of tension, such tension that may be holding the mask with the seal 412 on the face, and helps to alleviate discomfort using human , wearing skin damage and excessive tension inherent with other issues.

另外,在头戴具414上可能希望采用一个以上的枕骨气垫416,如果采用一个以上的枕骨气动垫416,则枕骨气垫416可以放在若干围绕头戴具414的若干位置上。 In addition, the wearing tool 414 may wish to use more than one occipital cushion 416, if more than one occipital pneumatic pad 416, the occipital cushion 416 can be placed in several locations around the headset with several of the 414. 另外,多个枕骨气垫416中的各个气动垫可以彼此独立地充气和放气。 Further, each of the plurality of pneumatic occipital cushion pad 416 can be independently of each other inflated and deflated. 这种方式可以更容易补偿患者面部的不对称性,因为可以在局部的和在只需要的地方在头戴具414中作用张力。 This embodiment may be easier to compensate for asymmetry of the patient's face, as can be partial and only where needed in the headset 414 having the role of tension. 因此在面罩组件中的压力分别增加或者降低时,可以使多个枕动气垫416充气或者放气,或者可以通过传感和控制系统使这些气动垫充气和放气,这些传感和控制系统是基于测量漏气量工作的。 Thus the pressure in the mask assembly is increased or decreased, respectively, may be a plurality of movable cushion 416 inflated pillow or deflated, or may make these Pneumopillows inflated and deflated through the sensing and control system, the sensing and control system based on the measured air leakage work.

在本发明的另一实施例中,可以采用形状记忆合金(SMI)丝例如MIUSCLE WIRES(Mondo-Tronics,Inc,San rafael,CA,USA)作更灵敏的张力部件,该合金丝在通电流时收缩。 In another embodiment of the present invention may be employed a shape memory alloy (SMI) filaments e.g. MIUSCLE WIRES (Mondo-Tronics, Inc, San rafael, CA, USA) for the more sensitive the tension member, through which the current alloy wire contraction. (通常,通电池时产生的收缩响应是由于电流通过它引起合金丝的加热。)如果使用这种类型的部件来达到灵敏的张力调节,则需要配置分开的控制器以便使该合金丝与面罩压力增加同步的收缩。 (Typically, the shrinkage generated when the response is due to the current through the battery caused by its heating alloy wire.) If this type of sensitive components to achieve tension adjustment, the need to configure the controller to separate the alloy wire and the mask increased systolic pressure synchronized.

其他合适的灵敏张紧部件包括伺服马达和用biomimetic材料形成的“人造肌肉”。 Other suitable tensioning member comprises a sensitive servo motor and formed with a biomimetic material "artificial muscle."

D.算法按照图16所示实施例的枕骨气垫416例如一开始便充气到预定的张力。 D.

在这些实施例中,用作为面罩压力仿射函数的压力充气枕骨气垫的方法包括:用压力传感器测量面罩压力,产生正比于面罩压力的信号;将信号加在增益和偏差可调的放大器上;将放大器的输出加到电压可控的压力源上;用上述压力源中的气体充气枕骨气垫;调节偏差使得面罩在最小要求压力达到密封;调节增益,使得面罩可以在最高要求压力下达到密封。 In these embodiments, the method inflatable occipital cushion pressure as a function of mask pressure affine comprising: measuring mask pressure pressure sensor, generates a signal proportional to the mask pressure; and a signal applied to the adjustable gain and offset amplifier; the amplifier output voltage is applied to the controllable pressure source; inflatable occipital cushion with said pressure gas source; control deviation such that the minimum required pressure to the mask seal; adjust the gain so that the mask can be achieved at the highest required pressure seal.

在这些实施例中,如果压力传感器来的信号Vpt是Vpt=KptPmask,则可控压力源产生压力Pc=KcVc,面罩与面部接触面积在向后方向的投影面积是Amask,带与枕骨气动垫接触面积在向前方向的投影面积是Abladder,在零压力达到密封所需要的力是F0,则放大器输出以下输出电压:Vout=F0/Abladder+Amask/AbladderKc/KptVin在一些实施例中,用压力为面罩压力仿射函数的压力充气枕骨气垫包括:将面罩通过第一软管连接于包含第一活塞的第一气缸,该第一气缸又通过连杆连接于第二气缸中的第二活塞,第二气缸通过第二软管连接于枕骨气垫;偏压上述连杆,使枕骨气垫充气,充到足以使面罩能够在最低预定使用压力下达到密封。 In these embodiments, if the pressure sensor signal is Vpt Vpt = KptPmask, controllable pressure source is a pressure Pc = KcVc, a face mask and a contact area of ​​the projected area in the rearward direction is AMASK, in contact with the occiput Pneumopillows area in the forward direction of the projected area of ​​Abladder, at zero pressure reaches the desired sealing force F0 is, the output of the amplifier output voltage: Vout = F0 / Abladder + Amask / AbladderKc / KptVin in some embodiments, pressure is affine function of the pressure mask pressure inflatable occipital cushion comprising: a first mask by a hose connected to the first piston comprises a first cylinder, the first cylinder and the second cylinder is connected to the second piston by a connecting rod, a first two cylinder via a second hose is connected to the occipital cushion; bias the link, so that the inflatable occipital cushion, charge enough to enable the mask seal can be achieved at a predetermined minimum pressure.

在一些实施例中,利用弹簧和/或重物形成偏压力。 In some embodiments, the biasing force is formed by a spring and / or weight.

将面罩密封在患者面部上的装置包括:第一组可伸缩的带,这些带从头的后部通向面罩,该带被张紧,张紧到在最低的预定使用压力下使上述面罩密封在面部上;第二组不能伸缩的带,该带仍然从头的后部向前伸到面罩,并放在第一组带的上面;放在头后部的可充气枕骨气垫,该气垫位于第一和第二组带之间,上述枕骨气垫与面罩中的空气气动相通。 Means for sealing the mask on the patient's face comprising: a first set of retractable tape, with these leads from the head of the rear mask, the tape is tensioned, the tension to the mask so that the seal at the lowest predetermined pressure facial; not scale with the second group, with the rear portion of the head forwardly out into the mask remains, and on top of the first set band; on the back of the head of an inflatable occipital cushion, the cushion is in the first between the belt and the second set, the air cushion and the air above the occipital bone in communication with the mask.

在操作中,第一组可伸缩的带独立于面罩压力提供固定的恒定力,而通过第二组带起作用的气动垫提供随面罩压力线性变化的力。 In operation, with the first group of independent retractable mask pressure force provides a fixed constant, to provide a force with the mask pressure changes linearly through a second set of functions with a pneumatic pad. 这两个力加在一起,形成作为面罩压力仿射函数的力。 Together these two forces, the force formed as a function of mask pressure affine. 当枕骨气垫与头后部接触面积和枕骨气垫与第二组带的接触面积中较小一个接触面积的前向投影面积,与面罩接触面部面积的后向投影面积相同时,很接近最佳配置。 When the contact area of ​​the front and back of the head occipital cushion occipital cushion contact area and the second group with the smaller contact area to a projected area, the contact surface area with the mask to the projected area of ​​the same, very close to the optimal configuration .

在另一实施例中,将面罩密封地保持在患者面部上的装置包括:一组刚性带,该带从头的后部向前伸到面罩;放在上述带和头后部之间的半刚性弹性枕骨气动垫,该枕骨气动垫在内部大气压下,前部壁和后部壁之间具有非零的内部分隔距离;软管,将枕骨气动垫连接于面罩。 In another embodiment, the mask means includes a seal on the patient's face holding: a set of rigid strip which masks out into the rear portion of the head forwardly; placed between the rear part of the semi-rigid belt and the head occipital pneumatic elastic pad, at the occipital inner pad atmospheric air, having a non-zero separation distance between the inner front wall and a rear wall; a hose, a pneumatic occipital pad attached to the mask.

枕骨气垫可以方便地用弹性材料例如硅橡胶、乳胶或者聚氨酯制作,用有弹力的材料填充该气动垫,或者用一个或多个内部弹簧或外部弹簧,可以调节该气动垫的弹性,该有弹力的材料例如为硅橡胶泡沫、乳胶泡沫、聚氨酯泡沫和/或PVC泡沫。 Occipital cushion may conveniently be e.g., silicone rubber, latex or polyurethane production, filling the pneumatic cushion material with a resilient elastomeric material, or with one or more internal or external spring springs can be adjusted elasticity of the pneumatic cushion, the elastic the foam material such as silicone rubber, latex foam, polyurethane foam and / or PVC foam. 用充满密封有空气和/或流体的第二弹性内枕骨气垫可以形成舒适的内弹簧,该内枕骨气垫小于外枕骨气垫。 Is filled with a second resilient sealed air and / or fluid occipital comfort air cushion formed within the spring, the inner air bearing smaller than the outer occipital occipital cushion.

在内部大气压下,枕骨气垫前后壁之间前后分开距离较好为约2-4cm,最好为3cm,以便允许颈部在适当的范围内运动,而不过分增加或者降低带作用力,并在面罩压力增加时,允许在头后部(头发、皮肤、脂肪、肌肉)的部件和面罩软垫以及面部组织上有相当大的压力。 Under atmospheric pressure inside occipital cushion back and forth between front and rear walls separated by a distance of preferably about 2-4cm, preferably 3cm, so as to allow movement of the neck in an appropriate range, without excessively increasing or decreasing with force, and when the mask pressure is increased, allows considerable pressure on the rear portion of the head (hair, skin, fat, muscle) and mask cushion member, and facial tissue.

枕骨气动垫壁和任何充填泡沫或者弹簧的总的刚性最好是这样,使得这种刚性可以形成一种力,该力在带张紧到约中等时,或者低于不张紧长度约1.5cm时,足以使面罩在所有预定压力下达到密封。 Occipital pad wall is preferably air and filling any head rigid foam or spring is such that this may form a rigid force which the belt is tensioned about the middle or below the untensioned length of about 1.5cm , it is sufficient to seal the mask at a predetermined pressure all. 通常该力约为200-600g,这取决于面罩的特性和配合程度。 The force is typically about 200-600g, depending on the nature and degree of fit of the mask.

当带的张力在较高的面罩压力下增加时,面罩软垫和头后部的组织将被压缩。 When the belt tension is increased at higher pressures the mask, the mask cushion and the rear head tissue will be compressed. 这将导致枕骨气动垫膨胀,因为枕骨气动垫最好特意构造成刚性的,并且已经通过张紧带到低于其放松长度而被压缩,以便在任意低压下达到密封所需要的力F0,所以在枕骨气动垫膨胀时,该枕骨气动垫的弹性将提供越来越小的力。 This will result in expansion of the occipital pad pneumatic, pneumatic occipital pad as best specially configured rigid, and have been brought by tensioning below its relaxed length and is compressed in order to achieve the desired sealing force F0 in any low pressure, so when occipital pneumatic pad expansion, the occipital pneumatic pad will provide smaller and smaller elastic force. 应当采用其面积为Abladder的枕骨气动垫来补偿初级弹簧反冲力的这种损失,该面积Abladder大于面罩的面积Amask。 It uses an area of ​​the pneumatic Abladder occipital pad to compensate for this loss of primary recoil spring, Amask area greater than the area Abladder mask.

当枕骨气动垫受到压力作用时,并且向前作用在头的后部和向后作用在带上时,该垫的一部分平的横向部分将接触带,而在带两侧的弯曲部分不会接触该带。 Occipital pad when subjected to a pneumatic pressure, and the effect of the forward and backward action of the rear head in the tape at the lateral portion of the flat portion of the contact pad with, and on both sides of the bent portion does not contact with this belt. 仅与带接触的面积,具体是该面积向前投影面积,将产生有用的带张力。 Only the contact area with the belt, in particular the area of ​​the forward projection area, the belt tension to produce useful. 实际上,对于典型尺寸的成人面部面罩,例如采用左右尺寸约17cm、上下尺寸约11.5cm和厚度3cm的气胆是合适的。 In fact, for a typical adult facial mask size, for example with a size of about 17cm or so, the vertical dimension of about 11.5cm and a thickness of 3cm bladder is suitable. 与带接触的投影面积左右尺寸约15cm,上下尺寸约10cm,因而气胆的作用近似于面积为150cm2活塞的作用。 Right and left in contact with the projected area with a size of about 15cm, the vertical dimension of about 10cm, thus acting similar to bladder area of ​​150cm2 acting piston. 当然这些仅仅是按照喜好和/或应用而变更的例子。 Of course, these are merely examples according to preference and / or application changes.

图53A-53C示出一个实施例,在此实施例中,框架具有大体三角形的形状,在此例中该框架构造成为可以支承全面部的面罩软垫,虽然该框架适合于用作鼻子软垫的框架。 FIGS 53A-53C illustrate one embodiment, in this embodiment, the frame has a generally triangular shape, in this case the frame may be configured to support full face mask cushion portion, while the frame is suitable for use as the cushion nose s frame. 该框架600可以包括其他形状例如大体圆形的、梯形的或者适合患者预定区域的起界面作用的任何形状。 The frame 600 may comprise other shapes, such as generally circular, trapezoidal or any shape appropriate for the patient interface plays the role of a predetermined area.

该框架600包括一对侧面部件605,各个侧面部件包括连接件界面610,该界面具有至少一个孔,最好具有许多孔615。 The frame 600 includes a pair of side members 605, each side member 610 includes a connector interface, the interface having at least one aperture, preferably having a plurality of holes 615. 各个孔615构造成为可以接收头带的端部,最好可以接收上述基本上不能伸缩的头戴具带的端部。 Each aperture 615 is configured as a receiving end of the headband can be, for receiving the end portion may preferably be substantially not stretchable band with wearing. 该头戴具带可以连接于孔615中任一孔。 The headset may be connected to the hole with tape to any one of holes 615. 另外,这些孔形成在连接件界面610的侧壁617上。 Further, the holes formed on the connection member side walls 617,610 of the interface.

如图53B和53C所示,向着患者面部的表面616包括一对肋片620,该肋片配置成在使用时位于患者鼻子两侧的正外侧。 As shown in FIG. 53B and 53C, toward the surface of the patient's face 616 includes a pair of ribs 620, the rib configured to be positioned outside of the positive sides of the patient's nose in use. 如图53B所示,肋片620配置在患者鼻子的鼻梁区域,但是该肋片620也可以沿患者鼻子两侧边更大或者整个部分延伸。 As shown in FIG. 53B disposed ribs 620 in the nasal bridge region of the patient's nose, but the rib 620 may be larger along the entire side edges, or portions of the patient's nose extends. 该肋片620构造成为可以装在面部软垫(未示出)上或者在软垫外侧形成的相应槽或者沟槽中。 The rib 620 is configured to the corresponding groove or grooves can be mounted on the face cushion (not shown) formed on the outside of the cushion or the. 各个肋片包括一个或多个孔625,该孔有助于在肋片和软垫之间形成锁闩,并且还可以减轻重量。 Each of the fins 625 includes one or more apertures, the aperture helps cushion formed between the fins and the latch, and may also reduce the weight.

在使用时,肋片620形成一定程度的侧向支承,从而有助于保持对患者两侧的良好密封。 In use, the lateral support ribs 620 are formed to some extent, thus contributing to maintaining good sealing of the sides of the patient. 例如,当增加带的张力时,通常的垫将趋向于侧向向外形成波浪形,由此增加损害软垫密封性或者舒适性的可能性。 For example, when increasing the belt tension, the pad will tend to generally laterally outwardly undulated, thereby increasing the possibility of damage or sealing cushion comfort. 形成肋片620也有助于防止软垫向外起波纹,从而有助于保持对鼻子两侧的密封。 Forming ribs 620 also helps prevent the cushion outwardly corrugated to help maintain a seal both sides of the nose.

该框架构造成为具有柔性,从而可以绕轴线A转动、弯曲或者形变。 The frame is configured as a flexible, thereby axis A, around a bend or deformation. 这样,当张紧头带时,该框架600可以绕轴线A运动,由此使肋片向内运动,对患者鼻子两侧加压。 Thus, when the tension of the headband, the frame 600 may be rotated about axis A, whereby the inward movement of the fins, the pressure on both sides of the patient's nose. 另外或者按照另一种方式,在使面罩侧部弯曲、转动或者形变时,如图53C的箭头所示,框架600的顶部分601将向患者鼻梁区域弯曲、转动或者形变,如图53B的箭头所示。 Additionally or in another way, when the mask portion side bent or deformed when rotated, as shown by arrows in FIG 53C, a top frame portion 601 will be bent 600 patients with nasal bridge region, rotation or deformation, the arrow 53B in FIG. Fig. 在起始位置,顶部分601弯离患者的面部。 In the starting position, the top portion 601 bent away from the patient's face. 因此,调节侧部带可以增强鼻梁区域的密封,从而不要顶部带。 Thus, modulation may enhance the sealing band side portion of the nasal bridge region, a top tape so as not to.

当面罩围绕主垂直轴A形变时,框架趋向于沿副水平轴线B变直。 When the mask is deformed about a primary vertical axis A, along the sub-frame tends to straighten the horizontal axis B. 这造成框架600的顶端601更移近面部,因而软垫压在鼻梁上。 This causes the frame 600 to the top 601 moves closer to the surface, and thus cushion the pressure on the nose.

这种作用主要在于,当框架绕一个轴线弯曲时,已经绕另一轴线弯曲的框架部分将承受更大应变。 The main effect of this is that, when the frame about a bending axis, about the other axis has a curved frame portion will be subjected to greater strains. 因此,为了尽量减小材料中的应变,它将使固有的弯曲变直,变到较低应变能的位置。 Accordingly, in order to minimize the strain in the material, it will inherently curved straight, to change the position of the lower strain energy. 当固有弯曲离开面部时,使固有弯曲变直将使那部分面罩更靠近面部。 When leaving the natural bending portion, so that will straighten natural bending portion closer to the face mask.

可以看出,通过改变不相关的平面弯曲位置和方向,可以使框架任何的要求部分移向或者移离到像在一个已知平面上弯曲框架一样的令人满意。 As can be seen, by changing the position and orientation of the bending plane irrelevant, the frame can be of any required portion toward or away from the frame to the image on a curved plane known as satisfactory.

换一种方式或者再加上,框架600包括一条或者多休强度减弱的线630,例如活页的铰接线,如形成在框架600顶部和/或底部上的活页的铰接线。 On another way, or together, or a multi-frame 600 comprises a reduced strength 630 off-line, e.g. leaflet hinge line, as formed in the frame 600 and the top / hinge line of the leaflet or on the bottom. 该强度减弱的线600将使框架600更容易地绕轴线A活动。 The line of weakness 600 of the frame 600 will be more easily about the axis A Activity.

图60A-60C分别示出本发明第二实施例软垫组件200、MIRAGE软垫和ACLAIM软垫的机械特性。 FIGS 60A-60C illustrate a second embodiment of the cushion assembly embodiment 200, MIRAGE ACLAIM upholstered cushion and the mechanical properties of the present invention. 图60D示出在一个坐标系统中三个软垫的比较。 FIG 60D shows a comparison of three cushions coordinate system. y轴代表相对软垫高度h/ho,而x轴代表作用在软垫上的压力F。 The y-axis represents the relative cushion height h / ho, and the x-axis represents the pressure acting on the cushion F. 该压力表示为作用在软垫组件上最大压力的百分数。 This pressure is expressed as a percentage of the maximum pressure acts on the cushion assembly.

参考图60A,在主要对应于膜210的开始区域,施加最大力的约20%的压力,软垫高度减小到约95%。 Referring to FIG 60A, the main region corresponding to the start of the film 210, pressure is applied maximum force of around 20%, the height of the cushion is reduced to about 95%. 在对应于软垫组件200柔性部件230的第二区域,施加约60%最大力的压力时,压缩从95%增加到80%。 In the second region 200 of the flexible member corresponding to the cushion assembly 230, about 60% of the maximum force applied to the pressure from the compression of 95% to 80%. 在对应下层软垫220的第三区域,力增加到最大压力的100%,只能稍微压缩软垫组件200。 In a third region corresponding to the lower cushion 220 to 100% of the maximum pressure force of the cushion assembly 200 is only slightly compressed.

图60B示出MIRAGE软垫的机械特性。 FIG 60B shows the mechanical properties MIRAGE cushion. 在对应于膜的区域施加约50%最大压力的压缩力可以得到约75%的压缩,进一步增加压缩力则只造成软垫相对高度稍微下降,这对应下层软垫的压缩。 Compression force about 50% of the maximum pressure in the film area corresponding to about 75% can be compressed to further increase the compression force caused only a slight decrease relative height cushion, which corresponds to a lower compression pad.

图60C示出ACLAIM软垫组件的机械特性,用较小的力便可以相当容易地达到约90%的起始压缩。 Figure 60C shows the mechanical properties ACLAIM cushion assembly, a relatively small force can easily reach about 90% of the initial compression. 随后压力的进一步增加造成,施加约30%的最大压力将造成泡沫嵌入件的很大压缩。 Then a further increase in pressure caused about 30% of the maximum pressure exerted will cause a large compression of the foam insert. 施加的压力高于约30%的最大压力时,对ACLAIM软垫组件只产生很小的压缩或者甚至没有任何压缩,因为泡沫嵌入件已完全压缩在面罩外壳上。 When the applied pressure is greater than about 30% of the maximum pressure of the cushion assembly produces only a small ACLAIM compression or even without any compression, since the foam insert has been fully compressed in the mask shell.

压力负载形变(CLD)(compression load defletion)也是一种支承负载的度量,一般表示为在一定百分形变条件下的磅/英寸2(psi)在此测试中,压缩整个样品,测定的数值与泡沫厚度无关,只要厚度不超长度和宽度。 The pressure load deformation (CLD) (compression load defletion) is also a measure of supporting a load, typically expressed in pounds deformation percentage under certain conditions / inch 2 (psi) in this test, the compression of the entire sample, and the measured values regardless of the thickness of the foam, as long as the thickness does not exceed the length and width. 采用CLD来表示某种特制泡沫材料硬度和一些半柔性泡沫硬度的规格。 CLD employed to indicate some special foams and some semi-flexible foam hardness hardness specifications. 这些数值也可以用来测定在各种湿老化或者加热老化条件下,负载承受能力的变化。 These measured values ​​can also be used in a variety of wet aging or heat aging conditions, changes in load bearing capacity.

负载的压痕形变(ILD)(indenation load deflection)是一种负载承受能力的度量,表示为在给定泡沫百分形变条件下的磅负载/50英寸2。 Indentation load deformation (ILD) (indenation load deflection) is a measure of the ability to withstand load, represented at a given foam pound load conditions percent strain / 50 in2. 为了得到这一数值,将50平方英寸的圆板(a)推入泡沫材料的顶表面,在给定的形变状态下停止,并读出负载或者标度。 To obtain this value, 50 square inch circular plate (a) is pushed into the top surface of the foam material, stopping at a given deformation state, and read the scale or load. 例如,30的25%ILD意味着,需要30磅的负载才能将4英寸厚的泡沫材料板压缩到3英寸厚,负载越大,泡沫材料便越硬。 For example, 25% of ILD means 30, a 30-pound load to the foam material 4-inch thick plate compressed to three inches thick, the larger the load, the more hard foam material. 在此测试中,泡沫样品的尺寸大于圆板的尺寸,对于平板的泡沫材料,一般为15×15英寸。 In this test, foam samples of size larger than the size of the circular plate, the plate material for the foam, typically 15 × 15 inches.

在一些规范中,采用其他的板结构和尺寸定义ILD。 In some specifications, the use of other plate structure and size is defined ILD. ILD有时称为RMA(橡胶制造学会),从乳胶泡沫材料的同一测量得到。 ILD is sometimes referred to as the RMA (rubber Society), give the same measurement from the latex foam material. 表征柔性泡沫规格的推荐规程是:USU(Urethane Slab Uncored);USC(UrethaneSlab Cored);UMU(Urethane Molded Uncored);UMC(Urethane MoldedCored)。 Characterization of flexible foam specification procedures are recommended: USU (Urethane Slab Uncored); USC (UrethaneSlab Cored); UMU (Urethane Molded Uncored); UMC (Urethane MoldedCored). 在此码后面的数值表示25%ILD,例如USU-30是指具有30的25%ILD的无心平板泡沫材料,当测量值受到泡沫材料原厚度影响时,必须示出泡沫材料原来厚度。 In following this code value represents 25% ILD, e.g. USU-30 refers to a foam having a centerless plate 30 of the ILD of 25%, when the measured value by the influence of the original foam thickness, have shown the original foam thickness. (见BASF Wyandotte TechnicalAdvisory,“Effect of Foam Thickness on ILD”.)垂度系数是65%ILD与25%ILD之比,表示软垫质量。 (See BASF Wyandotte TechnicalAdvisory, "Effect of Foam Thickness on ILD".) Sag factor is 65% ILD of 25% ILD ratio, expressed padded quality. 高的数值表示接触到底的阻力。 High value represents the contact resistance in the end. 具有低垂度系数的泡沫材料通常“接触到底”,性能差。 A foam material having a generally low sag factor "contact in the end," poor performance. 这一系数的其他用语是SAG系数和SAG模量。 Other terms are the coefficients SAG SAG factor and modulus.

初始硬度系数(IFH)是25%ILD与5%ILD之比。 Initial hardness coefficient (IFH) and 25% ILD was 5% ILD ratio. 这一系数确定表面感觉。 This factor determining the surface feel. 柔性的或者软表面的泡沫材料具有较高的数值,而表面硬挺的泡沫材料具有较低的值。 Flexible or soft foam material having a high value of surface, and the surface of the stiff foam material having a low value. 初始硬度系数的另一用语是舒适系数。 Another factor is the initial hardness term comfort factor.

在测量ILD时,通常读取在25%变位、65%形变和在去掉负载后又回到25%形变的数值。 When measuring the ILD, typically read 25% deflection, 65% and back to 25% strain at removing the load after deformation values. 用开始25%形变值除以去掉负载时回到该25%形变值是恢复率,表示为%。 Back when divided by 25% of the set values ​​began to remove the load value is 25% deformation recovery rate, expressed as%. 对于作衬垫用,要求较高的恢复率,而用于吸收振动则要求底低的恢复率。 For use as a liner, require a higher rate of recovery, and for absorbing vibration of the bottom of the low recovery rate is required. 低恢复率的泡沫材料有时称为“无弹性”的。 Foam low recovery rate is sometimes referred to as "inelastic" in.

Indentation residual gauge load(ERGL)是另一种负载承受能力的计量,表示为一定负载的英寸值。 Indentation residual gauge load (ERGL) is another measurement of load-bearing capacity, expressed in inches the value of a certain load. 采用测量ILD的同一50平方英寸圆板,但是该板加载一定的负载。 Using the same disk measuring 50 square inches of the ILD, but the loading plate a certain load. 正常的加载是25磅、50磅或者75磅。 The normal load is 25 lbs, 50 lbs or 75 lbs. IRGL值用英寸表示。 IRGL values ​​are expressed in inches. 必须知道泡沫材料的原来厚度,以使得到的值有意义。 You must know the original thickness of the foam material, to make a meaningful value obtained. 这种度量经常用于说明汽车用泡沫材料规格。 This measure is often used to illustrate the car with foam material specifications. 在ILD和IRGL测量值之间没有现成的相关关系。 No existing correlation between ILD and IRGL measurements.

Guide factor是25%ILD与密度之比,该术语用于确定不同密度泡沫材料的相对硬度。 Guide factor was 25% ILD and density, the term is used to determine the relative density of the foam of different hardness. 密度越接近,越好比较。 The closer the density, the better comparison. 当密度不同时,具有最高Guide factor的泡沫材料具有成本优点。 When the density of the foam material is not the same, it has the highest Guide factor has the advantage of cost. 但是性能不一定好。 But performance is not necessarily good. Gride factor的另一用语是归一化的ILD。 Another term Gride factor is normalized ILD.

压痕模量(IM)是在20%ILD和40%的ILD范围内,产生1%压痕所需的负载。 Indentation modulus (IM) within the range of 20% ILD and ILD 40%, 1% to produce a desired indentation load. 该直线的斜率取决于微孔泡沫材料壁抗弯曲的能力。 Slope of the line depends on the ability microporous foam wall against bending.

回弹性是泡沫材料弹性或者弹力的一种度量。 It is a measure of the resilience or elastic force of an elastic foam material. 在此测试中,将钢球落在泡沫材料上,并将反弹表示为百分回弹性,和回复率一样,要求的值取决于应用。 In this test, the ball landed on the foam material, and expressed as a percentage rebound resilience, and recovery rate as required values ​​depend on the application. 对于很软的泡沫材料回弹性可能使人误解,因为在球的作用下,泡沫材料将接触到底。 For very soft resilient foam material may be misleading, because under the action of the ball, the foam will be in contact with in the end. 这样,即使泡沫材料是“灵活的”或者是弹性的,但是也得到很低的回弹性值。 Thus, even if the foam material is "flexible" or elastic, but also a very low resilience value. 球反弹是这一特性的另一用语。 Ball rebound is another term for this feature.

抗拉强度是在将泡沫材料拉伸而断裂所需应力量的一种度量,并表示为磅/英寸2(psi)抗张强度可用作质检控制,一种普通的测试是在加热老化之后,测定抗拉强度的变化。 The tensile strength of the foam material is stretched to be a measure of the force required to break, and expressed in pounds / inch 2 (psi) Tensile strength can be used as quality control, in a conventional heat aging test Thereafter, the measured change in tensile strength.

拉伸率一般在测定抗拉强度的同时进行测量。 Draw rate is generally measured at the same time the tensile strength. 拉伸率是在泡沫材料断裂之前能够拉伸的伸长量的度量,表示为原来长度的百分数。 Is a measure of the tensile elongation before breaking of the foam material is capable of stretching, expressed as a percentage of the original length.

抗撕强度是一种在泡沫材料已开始裂开或者断开之后,继续撕该泡沫材料所需力的一种度量,表示为磅/直线英寸(pli,或者更普通为pi)。 A tear strength after the foam material has started to rupture or disconnected, a measure of the force required to continue tearing the foam material, is in pounds / linear inch (PLI, or more generally as pi). 在需要对材料进行缝纫,用用钉子钉住或者“弯曲形成环形(hog-ringed)”的应用中,为确定在测定泡沫材料的适用性,这一特性是很重要的。 The need for sewing material, with a peg or nail "to form an annular bend (hog-ringed)" application, to determine the suitability of the foam was measured, this feature is very important.

压缩形变(compression set)是在可控的时间和温度条件下,保持泡沫材料压缩之后,泡沫材料形变的度量。 Compression set (compression set) after the under controlled time and temperature conditions, maintaining the foam material compressed foam measure deformation. 标准条件是在158条件下22个小时。 Under standard conditions 158 conditions 22 hours. 在这种测试中,将泡沫材料压缩到给定的厚度,表示为其原来厚度的百分数。 In this test, the foam material is compressed to a given thickness, it indicates a percentage of its original thickness. 压缩形变最普通表示为起始压缩的百分数。 The most common compression set expressed as a percentage of the initial compression.

疲劳是一种在模拟使用条件下负载承受能力损失的一种度量,一般表示为百分率负载损耗。 A measure of fatigue is a load bearing capacity loss under simulated conditions of use, the load loss is generally expressed as a percentage. 两个最普通的疲劳测试是静态疲劳测试和压辊剪切疲劳测试(roller shear fatinue)。 The two most common are fatigue testing static fatigue test shear fatigue test and the pressure roller (roller shear fatinue).

在静态疲劳测试中,将泡沫材料在室温下压缩到其原厚度的25%,压缩17小时,将计算ILD损失,表示为原值的百分数。 In a static fatigue test, the foam material is compressed at room temperature to 25% of the original thickness, the compression for 17 hours to calculate the ILD loss, expressed as a percentage of the original value.

在压辊剪切疲劳测试中,使比泡沫材料宽度长的压辊在泡沫材料上来回滚动。 In the pressing roller shear fatigue test, so that the width of the foam material than the long press rolls rolling back and forth on the foam material. 该辊装在可横向移动的位置,以便施加剪切作用力。 The roller is mounted laterally moved position, to apply shear force. 在应用恒定形变设定值或者恒定压辊重量时,测试方法不同,按照测试方法的说明,计算ILD或者IRGL的损失量。 Deformation upon application of a constant set value or a constant pressure roller weight, different tests according to the test method described, the calculation of the ILD or loss IRGL.

空气流量是泡沫材料孔隙率或者敞开程度的一种度量,表示为立方英尺空气/min(cfm)。 Foam air flow is a measure of the porosity or degree of opening, it expressed in cubic feet of air / min (cfm). 按照ASTM方法的说明,利用真空将空气抽过泡沫材料,或者按照BASF Wyandotte Technical Advisories报告的说明,利用装置,即“BWC便携式空气流量测量装置”和“BWC便携式空气流量测量改进型装置”,使空气吹过泡沫材料。 Follow the instructions of the ASTM method, a vacuum draws air through the foam material, or the instructions BASF Wyandotte Technical Advisories report by means i.e. "BWC portable air flow measuring device" and "BWC improved portable air flow measuring device", so that blowing air through the foam.

还有许多其他泡沫材料特性和测试方法。 There are many other foam characteristics and test methods. 其中许多已经研究出来,用于考虑到的特殊方面。 Many of which have come up for specific aspects taken into account. 在ASTM特殊泡沫材料规格部分中的标准方法D-1564和D-2406中,可以找到其他的术语定义和测试方法的说明。 Standard Method D-1564 and D-2406 in a special foam in ASTM specification section may find descriptions of the other definitions of terms and testing methods.
