Description

一种鼻腔扩张器 技术领域
本发明涉及扩张装置领域，尤其涉及一种鼻腔扩张器。
背景技术
目前，相当多的人患有鼻阻塞症(或称为鼻塞)。人体的鼻腔最狭窄处为鼻瓣区(鼻内孔)，该区域位于鼻前庭深部、下鼻甲前端的前方，呈狭长的三角形区域，是鼻阻力最大的部位。鼻阻塞通常发生于鼻瓣区和与其相邻的下鼻甲前端，通常因该区域粘膜肿胀、增生、肥大，以及鼻中隔偏曲等结构畸形所导致。鼻阻塞会引起呼吸不畅、打鼾等症状。
对于上述慢性和严重的鼻通道阻塞症状，一般采用外科手术进行治疗。但手术花费一般较大，也很难根治鼻通道变形问题，而且切除鼻甲后可能造成“空鼻症”等后遗症，给患者带来更大的痛苦。
另一种解决鼻阻塞的方法是使用鼻扩张器，通过扩张鼻通道的空间来提升鼻通道的通气性。专利号为PCT/CN2013/085002的专利就公开了这样一种鼻扩张器，该鼻扩张器主要包括两个不规则的环形鼻内支架和U形连接装置。将该鼻扩张器置于鼻前庭深部，两个不规则的环形支架从内侧支撑并扩张鼻瓣区(鼻内孔)附近的鼻翼内壁，扩大了鼻瓣区和下鼻甲前端的通气空间，从而缓解相应的鼻塞症状。
现有鼻扩张器的鼻内支架可分为筒状(或环状)和带状两种。筒状(或环状)支架参见美国专利公开号为US D575397 S1的专利公开文献。筒状(或环状)支架的优点是扩张力强，其缺点是空气阻力大、对不同形状鼻孔适应性差。带状支架的优点是舒适性好、对不同形状鼻孔适应性强，其缺点是支架两端扩张力不足。
发明内容
本发明的目的在于，为解决现有的鼻腔扩张器因结构限制，导致其扩张力不足或对不同形状鼻孔适应性差等技术问题，提供了一种鼻扩张器，其鼻内支架同时具备带状支架和筒状(或环状)支架的优点，使鼻扩张器同时具备了良好的扩张性、透气性、舒适性和适用性。
为实现上述目的，本发明提供的一种鼻腔扩张器，包括：两个鼻内支架和一条连接带，所述连接带的两端分别对称连接一个鼻内支架；所述的鼻内支架为弹性带状结构，其在垂直于该带状结构宽度方向的截面上呈直线形、弧线形、弓形或折线形，并沿该带 状结构的长度方向将其划分为：一侧的鼻中隔支撑段、中间的弯曲段和另一侧的鼻翼扩张段；通过压迫鼻内支架使其进一步弯曲后将鼻内支架插入鼻腔前庭内，使得鼻内支架在鼻腔内大致呈发箍状，也即其在垂直于鼻通道中轴线的截面上大致呈C形，利用鼻内支架特别是其弯曲段的回弹力，通过鼻中隔支撑段支撑在鼻中隔上，通过鼻翼扩张段从鼻腔内侧推挤鼻翼向外扩张，此时C形的缺口朝向鼻底。
作为上述技术方案的进一步改进，所述的两个鼻内支架均设有一条支撑臂，用于调整鼻内支架在不同位置的回弹强度和扩张强度，所述的支撑臂为弹性带状结构，其在垂直于该带状结构宽度方向的截面上呈直线形、弧线形、弓形或折线形，其两端固定于鼻内支架内侧面。
作为上述技术方案的进一步改进，所述的两个鼻内支架均设有至少两条支撑臂，所有的支撑臂均为弹性带状结构，其在垂直于该带状结构宽度方向的截面上呈直线形、弧线形、弓形或折线形，用于调整鼻内支架在不同位置的回弹强度和扩张强度，其中一条支撑臂的两端固定于鼻内支架内侧面；其余支撑臂的两端均固定于鼻内支架内侧面，或者其余支撑臂的一端固定于鼻内支架内侧面，其另一端固定于其他支撑臂上，或者其余支撑臂的两端均固定于其他支撑臂上。
作为上述技术方案的进一步改进，所述连接带的两端连接到鼻中隔支撑段朝向鼻孔外的一侧，或者连接到弯曲段朝向鼻孔外的一侧，或者连接到支撑臂朝向鼻孔外的一侧。
作为上述技术方案的进一步改进，所述的支撑臂与鼻内支架、所述的连接带与鼻内支架之间均采用一体式无缝连接，或者采用插接式连接，或者采用粘接式连接。
作为上述技术方案的进一步改进，所述鼻内支架的两端形成平滑地钩形结构。
作为上述技术方案的进一步改进，所述的两个鼻内支架的两端之间均连接有一条支撑臂，使得鼻内支架呈环形。
作为上述技术方案的进一步改进，所述的连接带为大致呈U形或C形或V型的条带结构或柱状结构。
作为上述技术方案的进一步改进，所述的两个鼻内支架各自所在平面(即垂直于每个鼻内支架宽度方向的平面)之间朝向连接带U形开口方向的夹角为90度～180度。
本发明所涉及的一种鼻腔扩张器的优点在于：
1、与筒状(或环状)支架相比，本发明的优势在于：第一，与固定周长的筒状(或环状)支架相比，本发明的鼻内支架为开口设计，可根据鼻孔大小及形状调整开口大小，适用于多种尺寸和形状的鼻孔，适用性更强，特别是对于鼻中隔偏曲的患者，其左右鼻孔大小不同，本发明的开口设计能够使左右鼻内支架分别匹配两个不同尺寸的鼻孔；第二，在保持同等支撑强度的情况下，本发明的鼻内支架在垂直于鼻通道截面上呈C形结 构，比筒状(或环状)支架的O型结构缩减了横截面积，透气性和舒适性更好。
2、与带状支架相比，本发明的鼻腔扩张器的优势在于：第一，带状支架的回弹性主要作用于鼻翼靠近鼻背(鼻梁)的部位，对于鼻翼中部和鼻翼沟附近缺乏支撑，本发明的支撑臂可以为鼻翼的各个部位提供支撑，特别是对于白种人的狭长形鼻孔，其鼻背(鼻梁)到鼻翼沟之间的长度较大，此时支撑臂对提升鼻翼中部和鼻翼沟附近的扩张效果极为关键。还可根据需要灵活调整支撑臂位置、数量和强度，因此应用范围更广；第二，鼻内支架和支撑臂相互固定，在插入鼻腔后不易变形；第三，鼻内支架和支撑臂的形状设计更加灵活，例如对于狭长形鼻孔，鼻内支架在自然状态下的弯曲弧度可以更大，使用者更易将其插入鼻孔，也不会因为回弹力过大而造成不适，此时由于支撑臂的存在，鼻内支架在各个位置仍可保持必要的回弹性；本发明的鼻腔扩张器避免了对于一般带状支架，由于鼻内支架弧度过小而造成鼻背(鼻梁)附近因弹力过大，给使用者造成不适，或者由于增加了弧度而造成回弹力不足；第四，由于支撑臂的存在，使鼻内支架的弹性设计更加高效，因此鼻内支架的厚度可以薄于一般带状支架，虽然增加了支撑臂，但整体空气阻力可与带状结构基本相当。
3、如果连接带与鼻内支架之间采用插接式设计，则可方便地根据不同鼻前庭内腔的形状和鼻中隔的形状更换鼻内支架和连接带，增加了鼻扩张器的适用范围。
4、两个鼻内支架弯折成C形后，各自所在平面之间朝向连接带U形开口方向的夹角为90度～180度，保证鼻内支架的支撑力正向作用于鼻翼方向，从而起到有效的扩张效果。

下面结合附图和实施例对本发明所述的一种鼻腔扩张器进行详细说明。
如图1所示，本发明所提供的一种鼻腔扩张器，包括：两个鼻内支架1和一条连接带2。所述连接带2的两端分别对称地与一个鼻内支架1连接，将鼻腔扩张器连接为一个整体。所述的两个鼻内支架1在使用过程中，分别进一步弯曲后插入使用者的两个鼻孔内，利用其自身回弹性来扩张鼻瓣区附近的鼻腔通道，从而提升鼻腔的通气效率。所述连接带2的两端随鼻内支架进入鼻孔内，连接带2的中间部分跨越鼻中隔露在鼻外，使用者可通过向外拉动连接带2来摘下鼻腔扩张器。
所述的鼻内支架1用弹性材料制成，其形状为不规则的带状结构，将其拉直或展平后，从立体的3D维度来看，其总体特征是一个维度(长度)最长，一个维度(宽度)次长，另一个维度(厚度)最短或最薄。此时鼻内支架1拥有正反两个最大面、两个次小面、和两个最小面。在自然状态下，此不规则的带状结构在垂直于其宽度方向的截面上呈直线形、弧线形、弓形或折线形，即其最大面沿其长度方向可朝其法向一侧有一定程度的弯曲或弯折，成为曲面。另外，如图2所示，其宽度和厚度在不同位置也可有所不同，其中x、y、z分别表示鼻内支架1的宽度方向、长度方向和厚度方向。
所述的鼻内支架1是用来支撑和扩张鼻通道的主要部件，如图1所示，沿该鼻内支架1的带状结构的长度方向，根据功能将其分为三段，即：中间部位的弯曲段4、一侧的鼻中隔支撑段3、另一侧的鼻翼扩张段5。自然状态下，两个鼻内支架1的鼻中隔支撑段3的长度方向基本平行，如图3所示，两个鼻内支架内侧面12分别朝向两个鼻内支架1对称面的两侧。当使用者将鼻内支架1进一步弯曲并插入鼻孔内时，鼻内支架1呈发箍形状，此时在弯曲段4处发生的弯曲最为显著，而根据各鼻腔的不同尺寸和形状，鼻中隔支撑段3和鼻翼扩张段5也可能发生一定的弯曲变形。如图4所示，从垂直于鼻通道中轴线的截面上看，鼻内支架1的截面形状近似为C形(也可能为U形、V形或弓形等)，此时鼻内支架1的宽度方向与鼻通道中轴线基本平行，C形实线部分就是鼻内支架1最长边与最短边在该处围成的面在进一步弯曲后的呈现。如图6所示，此时，上述C形实线的中段即为弯曲段4，其朝向为使用者的鼻梁(鼻背)方向；C形实线的一 侧为鼻中隔支撑段3，其朝向为所在鼻孔的鼻中隔方向；C形实线的另一侧为鼻翼扩张段5，其朝向为所在鼻孔的鼻翼方向；而C形的缺口朝向使用者的鼻底11。当使用者将鼻腔扩张器安放至鼻腔前庭8内后，由于鼻腔的鼻中隔10一侧较为固定，而鼻翼9一侧较易活动，因此，鼻内支架1以鼻中隔10为支撑基础面，利用自身的回弹性，以其鼻翼扩张段5将鼻翼9向鼻腔外侧撑开，从而扩张鼻通道。此时，鼻内支架1的最大面紧贴鼻通道内壁，可以有效支撑鼻通道、合理分散压力，使佩戴者感到更舒适；鼻内支架的次小面朝向鼻通道，由于其宽度(即鼻内支架1的厚度)极小，因此对空气阻力很小。
基于上述结构的鼻腔扩张器，所述的鼻内支架1为适应不同鼻形的需要，在自然状态下，即未插入鼻腔状态下，在垂直于其宽度方向的截面上(此截面与上述近似C形截面的角度相同)，该鼻内支架的截面形状可为直线形、弧线形、弓形或折线形等。
如图1、2所示，为了防止插入鼻腔内的鼻内支架1的两端尖锐而给使用者带来不适，其两端均可向该鼻内支架1内侧面12方向略弯曲，形成平滑地钩形结构7。这样，在鼻内支架1插入鼻腔后，在其上述近似C形的截面上，C形两个分支的端点附近略向C形中心弯曲，以避免端点直接接触鼻腔，造成使用者不适。此弯曲的弧度和半径不宜过大，以防止弯曲的钩形结构7对呼吸形成额外阻力。
另外，如图3所示，所述的鼻内支架1设有支撑臂6，所述的支撑臂6与上述鼻内支架1的结构相似，也呈不规则的带状结构。所述的支撑臂6是用来加强鼻内支架1的支撑力和弹力的核心部件。所述支撑臂6的数量可为一条或多条。在自然状态下，支撑臂6的宽度方向与所在鼻内支架1的宽度方向基本一致。如图3、图4、图5所示，当支撑臂6为一条时，沿其长度方向，其带状结构的两端分别连接在鼻内支架内侧面12上；而当支撑臂6为多条时，所有支撑臂6的两端均可连接在鼻内支架内侧面12上，如图8所示，也可有部分支撑臂6的一端连接在其他支撑臂6上，其另一端连接在鼻内支架内侧面12，或者其两端均连接在其他支撑臂6上。在特殊情况下，支撑臂的宽度可大于其长度。
在自然状态下，在垂直于支撑臂宽度方向的截面上，支撑臂的截面形状可为直线形、弧线形、弓形或折线形等。
如图4所示，当使用者将鼻内支架1进一步弯曲并插入鼻孔内时，从垂直于鼻通道中轴线的截面上看，此时支撑臂可发生弯曲、拉伸、压缩或其他变形，支撑臂6的宽度方向与鼻通道中轴线基本平行，使其次小面朝向鼻通道，由于支撑臂6的厚度很薄，所以其对呼吸的额外阻力也很小。此时，支撑臂6利用其自身回弹性，给鼻内支架1的弯曲段4提供额外弹力，给鼻中隔支撑段3和鼻翼扩张段5提供额外支撑力，从而优化鼻 内支架1的回弹效果。
基于上述结构的鼻腔扩张器，所述支撑臂6的两端与鼻内支架1的连接位置可沿鼻内支架的长度方向进行调整，从而达到不同的支撑效果。所述支撑臂6的宽度和厚度可与鼻内支架1不同。
如图1所示，所述连接带2的两端分别对称的与两个鼻内支架1朝向鼻外的次小面相连，具体连接位置可为鼻中隔支撑段3或弯曲段4或某条支撑臂朝向鼻外的面上，而在本实施例中，所述的连接带2连接于弯曲段4朝向鼻外的次小面上。
另外，如图9所示，所述两个鼻内支架1的两端之间均可连接有一条支撑臂6，使得鼻内支架1呈环形。
如图2所示，所述的连接带2与鼻内支架1之间可为一体式无缝连接，也可为插接式或粘接式连接；支撑臂与鼻内支架之间也可采用上述三种连接方式。所述的连接带为不规则的带状结构或柱状结构。如图10所示，在自然状态下，在穿过连接带两端和中间点的截面上，其截面形状可近似为U形、C形、V形或拱形等。另外，所述的两个鼻内支架1各自所在平面(即垂直于每个鼻内支架宽度方向的平面)之间朝向连接带U形开口方向的夹角为90度～180度，以保证鼻内支架1的支撑力正向作用于鼻翼方向，从而起到有效的扩张效果。
最后所应说明的是，以上实施例仅用以说明本发明的技术方案而非限制。尽管参照实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，对本发明的技术方案进行修改或者等同替换，都不脱离本发明技术方案的精神和范围，其均应涵盖在本发明的权利要求范围当中。
