Description

呼吸鼻塞、鼻塞配件及呼吸系统 技术领域
本申请涉及医疗器械技术领域，具体涉及一种呼吸鼻塞、鼻塞配件及呼吸系统。
背景技术
患者产生呼吸窘迫或呼吸衰竭等疾病时，往往需要进行呼吸支持。呼吸支持的方式包括无创通气及有创通气。为了尽量减少有创机械通气的并发症同时又可以有效治疗呼吸疾病，临床医生倾向于优先应用无创通气，根据无创通气支持效果决定是否给予有创机械通气。
因为患者的鼻腔尺寸差异很大，包括鼻孔孔径和鼻孔的间距。鼻塞的尺寸是否合适，关系到病人的舒适度，通气的气密性。同时呼吸机的治疗周期较长，可能长达几周到几个月。鼻塞的尺寸不合适可能会造成患者的面部皮肤压伤及鼻中隔损伤，为此对于长期使用呼吸机的治疗，临床上会建议医护人员，周期性松动患者与鼻塞的接触，改善舒适度及降低损伤。除此之外，对于鼻塞本身，厂家通过合适选材、调整材料的硬度，以及配套提供几个不同型号的鼻塞，供医护人员选择相对合适的鼻塞尺寸。
同一呼吸鼻塞如何去适应患者不同的鼻孔间距，现有产品没有好的方法，而这是造成患者鼻中隔压伤的主要原因。

本实施例中，第一调节件7可以连接在第一鼻塞管3或第二鼻塞管4上，单独移动一个鼻塞管。也可以设置在呼吸机连接件1上，并位于第一鼻塞管3和第二鼻塞管4之间，可同时移动第一鼻塞管3和第二鼻塞管4。
呼吸机连接件1为中空结构，通过进气通道101、第一出气通道103及第二出气通道104与外界连通。进气通道101可设于呼吸机连接件1的一端，第一出气通道103和第二出气通道104优选设置于与进气通道101相对的另一端。换而言之，第一出气通道103和第二出气通道104优选为与进气通道101在同一延伸方向上，如此可使得进气通道101进入的气体顺畅的流动到第一出气通道103和第二出气通道104，减少气体流动的阻碍。
具体而言，呼吸机连接件1包括进气管11，以及相对的底板12和顶板16，以及连接在底板12和顶板16之间的侧板13，底板12、顶板16和侧板13围合成一腔室102。进气管11与底板12连接，且进气管11围合的进气通道101与腔室102连通。第一出气通道103和第二出气通道104设置于顶板16，与腔室102连通。
优选的，腔室102的宽度(或长度)尺寸比进气通道101的宽度(或直径)尺寸更大，进气通道101进入的气体可以在腔室102内再分配均匀，使得经第一出气通道103和第二出气通道104流出的气体流量基本相同。当然，腔室102的宽度(或长度)尺寸与进气通道101的宽度(或直径)尺寸相同也可，只要能够实现气体的流通即可。
其他实施例中，进气通道101、第一出气通道103和第二出气通道104也可以设置在其他位置。例如进气通道101设在侧板13上，第一出气通道103和第二出气通道104设置在顶板16上；或者进气通道101、第一出气通道103和第二出气通道104均设置在顶板16上等。
本实施例中，第一出气通道103和第二出气通道104为在顶板16上开设的通孔，顶板16背向底板12的表面为平面，第一鼻塞管3和/或第二鼻塞管4在顶板16的平面上可移动。第一出气通道103和第二出气通道104的间隔距离为预设距离。以第一出气通道103和第二出气通道104均为顶板16上的圆形通孔为例，该预设距离为两者的圆心之间的距离，其范围优选为5-20mm，不同的预设距离可以做成不同的型号。根据不同年龄的患者选取不同的型号，例如婴幼儿可以选择5-10mm的型号，未成年人可以选择10-15mm的型号，成年人可以选择10-20mm的型号等，适用范围广。
侧板13之背向腔室102的表面连接有一外缘板14，外缘板14上连接有延伸板15，延伸板15相对顶板16之背向底板12的表面突出。外缘板14可以与顶板16平齐，即外缘板14的延伸平面与顶板16的延伸平面平行，且外缘板14的上表面与顶板16背向底板12的表面具有一共同的表面。延伸板15远离顶板16的一端还连接有盖板2。
其他实施例中，外缘板14可省去，直接将延伸板15连接在侧板13或顶板16上，延伸板15相对顶板16之背向底板12的表面突出。
一种实施例中，第一调节件7可移动的连接在顶板16或延伸板15上，且连接至第一鼻塞管3，以带动第一鼻塞管3移动。
另一种实施例中，第一调节件7可移动的连接在外缘板14或盖板2上，且连接至第一鼻塞管3，以带动第一鼻塞管3移动。
第一调节件7可以直接与第一鼻塞管3连接，还可以通过传动结构与第一鼻塞管3连接，该传动结构可以为连杆、齿轮、齿条、凸轮、涡轮、蜗杆的任意一种或多种的组合。或者，第一调节件7本身即为连杆、齿轮、齿条、凸轮、涡轮、蜗杆的任意一种或多种的组合。
一种实施例中，延伸板15上设有第一连接孔，第一调节件7与第一连接孔连接配合，且第一调节件7可相对延伸板15在第一出气通道103至第二出气通道104的连接方向上直线往复移动。第一鼻塞管3和第二鼻塞管4与顶板16背向底板12的表面连接，且第一鼻塞管3可在顶板16背向底板12的表面上移动。第一调节件7连接至第一鼻塞管3，第一调节件7可相对延伸板15移动，以带动第一鼻塞管3相对顶板16移动，从而调节第一鼻塞管3与第二鼻塞管4的间隔距离。
本实施例中，第一连接孔为螺纹孔，第一调节件7上设有与之对应的螺纹结构，第一调节件7转动，该螺纹结构与螺纹孔配合，使得第一调节件7相对延伸板15移动。
另一种实施例中，第一连接孔为光孔，第一调节件7可以相对第一连接孔沿直线滑动，使得推拉第一调节件7即可使得第一鼻塞管3相对移动。
第一调节件7可包括依次连接的操作柄71和调节杆72，操作柄71固定连接在调节杆72的一端，调节杆72外周表面上设有螺纹，用于与第一连接孔连接配合，使得调节杆72转动时，相对延伸板15移动。调节杆72之相对操作柄71的另一端用于连接至第一鼻塞管3。操作柄71为可选的设置形式，如不设置操作柄71，则通过调节调节杆72使得第一调节件7运动。
其他实施例中，第一调节件7与延伸板15之间还可以为其他传动配合型式，例如轴孔配合传动、齿轮齿条传动、涡轮蜗杆传动、凸轮连杆传动等。第一调节件7相对延伸板15 可仅有相对滑动，使得第一调节件7可带动第一鼻塞管3相对第二鼻塞管4移动。
一种实施例中，调节杆72的一端还连接有与第一调节块5配合的联动块74，第一鼻塞管3连接有第一调节块5。转动或推动操作柄71或调节杆72，可带动联动块74相对延伸板15移动，联动块74又带动第一调节块5移动，进而带动第一鼻塞管3移动。因此，调节第一调节件7可使得第一鼻塞管3相对移动。
另一种实施例中，与前一实施例基本相同，不同的是，第一鼻塞管3连接有第一调节块5，同时第二鼻塞管4连接有第二调节块6，调节调节杆72，以使联动块74带动第一调节块5和第二调节块6相对移动。调节第一调节件7可使得第一鼻塞管3和第二鼻塞管4同时移动，且两者产生相对移动，从而调节两者的间隔距离。
一种实施例中，第一调节块5包括主体板51、第一限位块52和第二限位块53，主体板51上设有限位孔502，第一限位块52和第二限位块53设置在主体板51上限位孔502的同侧，第二限位块53设置于第一限位块52远离限位孔502的一侧，第一限位块52和第二限位块53间隔设置，形成限位槽504，第二限位块53上设有凹槽503。联动块74卡设于限位槽504内，优选为与第一限位块52和第二限位块53紧贴设置，调节杆72容纳于凹槽503内。限位孔502用于套设在第一鼻塞管3外周，联动块74在转动过程中均容纳在限位槽504的空间内。当操作柄71转动带动调节杆72伸缩移动时，联动块74转动并随调节杆72移动，联动块74对第一限位块52施加推力或对第二限位块53施加拉力，从而带动第一调节块5随调节杆72移动，进而带动第一鼻塞管3移动。
一种优选的实施例中，调节杆72上还开设有周向的连接槽701，开设连接槽702的部分形成延伸杆73，延伸杆73与联动块74固定连接。当联动块74卡设在限位槽504内时，第二限位块53上的凹槽503的底壁与延伸杆73连接。换而言之，凹槽503开设到距离主体板51有一定高度的位置，第二限位块53的凹槽503的底壁相对主体板51突出，形成突出部531，突出部531用于伸入连接槽702并与延伸杆73连接。
一种优选的实施例中，主体板51上还固定连接有加强圈54，加强圈54沿限位孔502的周缘设置，使得加强圈54围合形成的空间为限位孔502，加强圈54用于增大第一调节块5与第一鼻塞管3的接触面积，增强连接稳定性。
一种优选的实施例中，主体板51呈矩形的板状，第一限位块52和第二限位块53的形状呈直线延伸的板状，第二限位块53设置在主体板51的一侧边缘，第一限位块53的延伸方向与第二限位块52的延伸方向相同，使得限位槽504的宽度始终保持一致。加强圈54的形状呈圆环形，加强圈54设置在与第一限位块52和第二限位块53之相对主体板51的同一侧表面，加强圈54的外周表面可以与第一限位块52连接，加强圈54在垂直于主体板51方向的高度可以与第一限位块52相同。第二限位块53上的凹槽503的中心线与限位孔502的轴线相交，使得联动块74设置在限位槽504内时，调节杆72的延伸通过限位孔502的轴线，即与第一鼻塞管3的轴线相交，有利于保持第一鼻塞管3移动时的稳定性。进一步的，调节杆72的延伸与第一鼻塞管3和第二鼻塞管4的轴线相交，三者可在同一个平面内，使得调节杆72伸缩移动时，第一鼻塞管3始终在靠近或远离第二鼻塞管4，结构简单。
调节杆72、延伸杆73和联动块74可均为圆柱形的形状，联动块74的直径可以与调节杆72的直径相同。为便于制作连接槽701，可以使用一根完整的圆柱形杆件沿周向开设 出连接槽701，即可得到调节杆72、延伸杆73和联动块74。操作柄71也可以为圆柱形，可在外周设置花纹以增强摩擦力，便于操作。
进一步地，呼吸鼻塞还可以包括标记第一鼻塞管3与第二鼻塞管4间相对距离的间隔标记。间隔标记可以包括第一刻度标记501和第二刻度标记601。
一种实施例中，第一调节块5上设有第一刻度标记501，第二调节块6上设有第二刻度标记601，通过测量第一刻度标记501和第二刻度标记601的间的距离，可以知道第一鼻塞管3与第二鼻塞管4间相对距离。
优选的，主体板51背向第一限位块52的表面还可以设有第一刻度标记501，第一刻度标记501可以为长条形槽，并可进行涂色以标记。第二刻度标记601与第一刻度标记501相似，参照即可。第一刻度标记501的延伸可通过限位孔502的轴线，使得第一鼻塞管3安装在限位孔502内后，第一刻度标记501用于标记第一鼻塞管3的中心，并与第二刻度标记601进行比较和测量，即可得到第一鼻塞管3移动的距离；抑或已知需调整的目标距离，通过测量第一刻度标记501与第二刻度标记601的距离即可知是否已经到达目标距离。
另一种实施例中，第一刻度标记501设置在第一鼻塞管3的外表面，第二刻度标记601设置在第二鼻塞管4的外表面，也可以实现测量距离。
第一鼻塞管3安装在限位孔502内后，第一鼻塞管3被第一调节块5限定位置，始终保持与呼吸机连接件1的顶板16的紧密连接，保证第一出气通道103与第一鼻塞管3的气密性。
具体而言，第一鼻塞管3包括依次连接的底管31、中管32和顶管33，底管31、中管32和顶管33共同围合形成第一管腔301，第一管腔301与第一出气通道103连通。底管31的一端紧贴在呼吸机连接件1的顶板16上，且底管31的外周壁面与第一调节块5的限位孔502配合连接，优选为底管31的外周壁面与限位孔502的孔壁紧贴，当然，也可以稍有一些空隙。底管31的外周直径保持一致，便于与限位孔502的配合。
中管32的外周的直径自与底管31连接的一端向与顶管33连接的一端逐渐减小，顶管33的外周的直径自与中管32连接的一端向远离中管32的一端逐渐增大，使得在中管32和顶管33连接的位置缩口的喇叭形状。顶管33用于伸入患者的鼻腔内，其喇叭形状有利于适应一定范围内的鼻孔尺寸，保证良好的密封连接，同时不易从患者的鼻腔内掉出，便于使用。
当第一鼻塞管3移动时，为了始终保证气密性，设置第一出气通道103的尺寸小于底管31的内径，且在第一鼻塞管3的移动的任意位置，底管31在呼吸机连接件1的顶板16上的投影始终覆盖第一出气通道103。其中第一出气通道103为圆形通孔时，其尺寸是指直径，当第一出气通道103为其他形状时，其尺寸是最大的空隙的距离，例如第一出气通道为矩形孔时，其尺寸是指对角线的距离。
可以理解的，第一鼻塞管3的移动具有极限，也就是说，具有距离第二鼻塞管4最近的距离和最远的距离。为了限制第一鼻塞管3的极限移动距离，可以设置位置限定结构，该位置限定结构可以为设置在第一调节件7、呼吸机连接件1等上的阻挡块等结构，当第一鼻塞管3移动到极限位置时，被阻挡快等结构限制进一步的移动。位置限定结构的具体结构不限，可以采用现有的各种结构。
可以理解的，该呼吸鼻塞还可以设置位置锁定结构，以使第一鼻塞管3移动到任意位置时可以锁定位置，例如，当第一鼻塞管3和第二鼻塞管4正好适合患者使用时，通过位置锁定结构锁定，锁定第一鼻塞管3的位置，避免再移动而影响使用。位置锁定结构的具体结构不限，可以采用现有的各种结构。
底管31与顶板16连接的一端的端部的外周还设有缘台34，缘台34相对底管31的外周表面突出，用于与第一调节块5配合而将第一鼻塞管3压紧在顶板16上。具体是第一调节块5的加强圈54远离主体板51的端部压紧缘台34。
一种实施例中，请参考图1至图3，该呼吸鼻塞还包括盖板2，盖板2连接在延伸板15上。盖板2上设有第一通孔21和第二通孔22，第一鼻塞管3通过第一通孔21伸出，第二鼻塞管4通过第二通孔22伸出。第一通孔21的直径大于第一鼻塞管3的外周直径，且第一通孔21的直径不小于第一鼻塞管21移动的极限距离。
第一调节块5设于盖板2之朝向呼吸机连接件1的一侧，并被盖板2压住，主体板51背向第一限位块52的表面与盖板2紧贴，盖板2压紧第一调节块5的主体板51，使得第一调节块5的加强圈54压紧第一鼻塞管3的缘台34，从而限制第一鼻塞管3沿自身轴向移动，即不能在垂直呼吸机连接件1的顶板16的方向上移动。第一调节块5的主体板51的尺寸大于第一通孔21的直径，使得第一调节块5移动时不会从第一通孔21弹出，始终被盖板2限制，结构稳定。
由于第一通孔21的直径大于第一鼻塞管3的外周直径，可以通过盖板2的第一通孔21的内壁与第一鼻塞管3外周表面直径之间的间隙观察到第一刻度标记501，从而可以进行测量。
进一步地，呼吸鼻塞还可以包括指示第一鼻塞管3与第二鼻塞管4间相对距离的刻度标尺。刻度标尺(图中未示出)可设置于盖板2上，刻度标尺的延伸方向与第一鼻塞管3和第二鼻塞管4的轴心的连线平行，第一刻度标记501和第二刻度标记601指向刻度标尺，通过读取第一刻度标记501和第二刻度标记601指向的刻度标尺的数值，得到第一鼻塞管3和第二鼻塞管4的间隔距离。
盖板2可以通过各种可行的方式连接在延伸板15上，例如胶接、螺接、扣接等，优选的，盖板2设置为可拆卸连接形式，方便拆卸盖板2而更换第一鼻塞管3和第二鼻塞管4，以及其他部件。
一种实施例中，底板12、侧板13、外缘板14、延伸板15和顶板16可以一体成型，使得呼吸机连接件1包括底板12、侧板13、外缘板14、延伸板15和顶板16。
另一种实施例中，底板12、侧板13和顶板16可以一体成型构成呼吸机连接件1，外缘板14和延伸板15可以为一个整体连接到呼吸机连接件1上。或者盖板2、外缘板14和延伸板15可以为一个整体连接到呼吸机连接件1上
一种实施例中，第二鼻塞管4固定在顶板16上，第一鼻塞管3和第二鼻塞管4之间的间隔距离通过移动第一鼻塞管3进行调节。
另一种实施例中，可通过与第一调节件7相似的第二调节件8来调节第二鼻塞管4移动。请参考图1至图3，呼吸机连接件1上设有与外缘板14和延伸板15相对的另一外缘板和延伸板。该延伸板上设有第二连接孔106，第二调节件8与第二连接孔106连接配合， 可相对该延伸板移动。第二调节件8还可与第二调节块6连接，第二调节块6用于连接固定第二鼻塞管4。通过调节第二调节件8带动第二调节块6移动，进而带动第二鼻塞管4移动。
本实施例中，第二调节件8的结构可以与第一调节件7相同，第二调节块6的结构可以与第一调节块5的结构相同，第二鼻塞管4的结构可以与第一鼻塞管3的结构相同，均参考即可，不再赘述。
本实施例中，第二出气通道104的设置方式与第一出气通道103类似，从而使得第二鼻塞管4的第二管腔401始终保持与第二出气通道104连通。

在呼吸机连接件1上还可连接绑带或提供绑带的安装孔，便于通过头帽、头带等将整个呼吸鼻塞固定于患者的面部或头部，进行稳定的固定，保证呼吸的稳定。

具体而言，第一出气管17和第二出气管18突出设置在顶板16之背向底板12的表面。第一鼻塞管3还包括弹性部35和连接管36，弹性部35连接在底管31之远离中管32的一端，连接管36连接在弹性部35远离底管31的一端。连接管35用于与第一出气管17连接，优选为套设在第一出气管17的外周。弹性部35具有弹性，可弯折和延伸，可在拉力的作用下伸长，解除拉力可缩回原状。弹性部35的材料可以采用具有较佳弹性的材料，例如橡胶、硅胶、塑料等。第二鼻塞管4的结构、设置可与第一鼻塞管3相同，这里不再赘述。
一种实施例中，第二鼻塞管4可为不可移动的结构，通过调节第一鼻塞管3即可调节两者之间的间隔距离。
另一种实施例中，第二鼻塞管4的结构可以与第一鼻塞管3相同，从而通过调节第二调节件8也可以调节第二鼻塞管4的位置，从而可同时调节第一鼻塞管3和第二鼻塞管4的位置。
