Description

血压袖带端盖及具有该端盖的血压袖带
【技术领域】
本发明涉及医疗设备领域，特别是涉及一种血压袖带端盖及具有该端盖的血压袖带。
【背景技术】
血压袖带是无创血压测量设备的关键部件。血压袖带直接与人体接触，采集人体血压波动信号，是进行血压测量的敏感元件。血压袖带由充气部分、导气管和气插头组成。充气部分在测量血压时充满气体并感应人体动脉搏动；导气管用来连接充气部分与气插头；气插头是连接血压袖带与外接导气管的连接端口。
一般的血压袖带，粉尘等细小颗粒易通过气插头进入袖带内部，袖带在测量过程中很容易在放气时造成气路堵塞；且血压袖带在清洗或者消毒时，易造成清洗消毒液体进入袖带内部，在血压测量过程中，因为放气时腐蚀液体的作用造成气路部件的腐蚀生锈，造成无创血压测量设备的使用寿命缩短。
【发明内容】
基于此，有必要针对气路堵塞和气路部件腐蚀生锈缩短无创血压测量设备使用寿命的问题，提供一种提高无创血压测量设备使用寿命的血压袖带端盖及具有该端盖的血压袖带。
一种血压袖带端盖，包括柔性的外圈部，所述外圈部开设有内孔，所述内孔为盲孔，所述外圈部通过所述内孔可过盈配合地夹紧于血压袖带气插头外壁。
在其中一个实施例中，还包括内塞，所述内塞设置于所述内孔底端，，并可嵌入血压袖带气插头内壁。

在其中一个实施例中，所述内塞自靠近所述内孔开口的一端端面至内塞侧面圆角过度处理。
在其中一个实施例中，所述内塞的高度低于所述外圈部的高度。
在其中一个实施例中，所述外圈部自所述内孔孔底处径向延设有引导部，所述引导部凸出于所述外圈部外缘。
在其中一个实施例中，还包括安装部，所述安装部一端连接于所述外圈部，另一端连接于血压袖带气插头。
在其中一个实施例中，所述安装部包括安装环和带条，所述带条一端连接于所述外圈部，且另一端连接于所述安装环，所述安装环用于套设血压袖带气插头。
在其中一个实施例中，所述血压袖带端盖为软胶类高分子材料式端盖。
在其中一个实施例中，所述外圈部的厚度自靠近所述内孔开口一端至另一端逐渐增大。
一种血压袖带，包括导气管、气插头和如上所述的血压袖带端盖，所述气插头一端插入所述导气管，另一端可通过所述血压袖带端盖密封。
在其中一个实施例中，所述气插头中部设有凸台，所述安装环位于所述导气管与所述凸台之间。
在其中一个实施例中，所述气插头的通过所述血压袖带密封端外缘中部环向凹设有气密槽。

【具体实施方式】
以下通过附图和具体实施例对血压袖带端盖及具有该端盖的血压袖带做进一步说明。
如图1和图2所示，一种血压袖带端盖100，包括外圈部120、内塞140和安装部160。
如图1、图2和图6所示，所述外圈部120开设有内孔122，所述内孔122为盲孔。内孔122可以是直盲孔，即是说所述内孔122为各截面孔径相同的盲孔，也可以是孔径逐渐变化的盲孔，在其他实施方式中也可以是以其他方式变化孔径的盲孔。所述外圈部120的厚度自靠近所述内孔122开口一端至另一端逐渐增大，所述外圈部120通过所述内孔122可过盈配合地夹紧于血压袖带气插头200外壁。
如图3、图5和图6所示，所述血压袖带端盖100可通过所述内孔122盖设于血压袖带的气插头200处。使用时，将血压袖带的气插头200插入所述内孔122，由于所述血压袖带端盖100的外圈部120为柔性，且所述内孔122的直径小于血压袖带气插头外壁220的径向尺寸，插入时所述外圈部120由于气插头200的径向挤压而弹性变形，插入后所述外圈部120即罩覆于所述气插头200外缘，并由于所述外圈部120的复位弹力而保持罩覆状态，不轻易脱出。从而防止清洗消毒液体或者粉尘等细小微粒进入气插头200内部，防止气路堵塞和气路部件腐蚀生锈，提高血压测量设备的使用寿命。
在其中一个实施例中，所述外圈部120侧壁的厚度自所述内孔122开口的一端至另一端逐渐增大。即是说，所述外圈部120在内孔122开口处壁厚较薄，易于变形，从而便于血压袖带的气插头200插入所述内孔122。所述外圈部120在内孔122孔底处壁厚较厚，气插头200插入所述内孔122后可以提供足够的保持力，防止血压袖带端盖100轻易从气插头200脱落。所述外圈部120的这种开口处薄壁底部厚壁结构，既提高了血压袖带端盖100的使用便利性，又提高了使用可靠性。
如图3所示，在一个实施例中，所示外圈部120呈圆台状。外圈部120的圆台状结构为血压袖带端盖100装配到气插头200上提供了均衡的挤压力。当然，在其它实施例中，所述外圈部120形状也可以为多边形台状等其它结构，这并不影响所述血压袖带端盖100对血压袖带的气插头200的插拔罩覆目的。
如图1所示，在其中一个实施例中，所述外圈部120自所述内孔122孔底处径向延设有引导部124，所述引导部124凸出于所述外圈部120外缘。当将血压袖带端盖100密封于所述气插头200开口或者将血压袖带端盖100与气插头200进行分离时，需要施加一定的外力，这时可通过所述引导部124施加外力，避免直接施加外力于外圈部120上，造成损坏外圈部120的风险。另外还可以方便使用者施加这个外力，比如通过手指施力时，可以降低血压袖带端盖100反作用于手指的阻力感。应当理解的是，即使不设置引导部124，亦不影响所述血压袖带端盖100密封于气插头200开口，以防止清洗消毒液体或者粉尘等细小微粒进入气插头200内部的目的。故引导部124的设置并不是必须的。
如图2所示，在其中一个实施例中，所述内塞140设置于内孔122底端。这样，血压袖带的气插头200插入所述内孔122时，内塞140将插入所述气插头200内，插入后，气插头200外缘由所述血压袖带端盖100的外圈部120罩覆密封，而气插头200气孔由所述内塞140填充堵塞而密封，防水防尘效果更好。
如图2和图6所示，在其中一个实施例中，所述内塞140呈圆台状，其径向尺寸自靠近所述内孔122开口的一端至另一端逐渐增大，其靠近所述内孔122开口的一端径向尺寸小于所述气插头内壁240的直径。所述内塞140远离所述内孔122开口的一端径向尺寸大于所述气插头内壁240的直径。这样，气插头200插入所述内孔122后，所述内塞140与所述气插头200气孔的配合自间隙配合逐渐过渡至过盈配合。既便于内塞140顺利插入气插头内壁240，同时内塞140插入气插头内壁240后，所述内塞140过盈配合地嵌设于所述气插头内壁240，因而密封效果好，进一步防止清洗消毒液体或者粉尘等细小微粒进入气插头200内部，防止气路堵塞和气路部件腐蚀生锈，提高血压测量设备的使用寿命。
如图2和图6所示，在其中一个实施例中，所述内塞140自靠近所述内孔122开口的一端端面至内塞140侧面圆角过度处理。如此更加便于内塞140顺利插入气插头内壁240，同时，在内塞140插入气插头内壁240的过程中，圆角过度处理的内塞140不易造成气插头内壁240的损坏，进一步提高了血压袖带的使用寿命。当然，若所述内塞140自靠近所述内孔122开口的一端端面至内塞140侧面不进行圆角过度处理，亦不影响使用。
如图2和图6所示，在其中一个实施例中，所述内塞140的高度低于所述外圈部120的高度。当然内塞140也可以与外圈部120平齐或者超出外圈部120小段长度。气插头200中部设有凸台260，在血压袖带与外接导气管连接为一起工作时，所述气插头200一端插入血压袖带中的导气管300，且另一端插入外接导气管，所述凸台260贴合于所述血压袖带的导气管300与外接导气管之间。当血压袖带与外接导气管分开时，将所述血压袖带端盖100密封于气插头200开口。所述外圈部120夹紧所述气插头外壁220，且所述外圈部120开口端端部与所述凸台260紧密贴合，从而更进一步提高了防水防尘效果；又便于血压袖带的安放。同时所述内塞140过盈配合地嵌设于所述气插头内壁240，且所述内塞140的高度小于所述外圈部120的高度，便于内塞140插入气插头内壁240，同时节省材料。
如图1和图3所示，所述安装部160一端连接于所述外圈部120，且另一端连接于所述血压袖带气插头200。当血压袖带不需要使用血压袖带端盖100时，将血压袖带端盖100从气插头200上取下，血压袖带端盖100通过安装部160与气插头200连接，而不需要放入其它专门放置血压袖带端盖100的设备中，方便使用，而使用完毕想要将气插头200盖上的时候也不需要花时间再从其他位置寻取血压袖带端盖100。应当理解的是，即使不设置所述安装部160，这并不影响血压袖带端盖100在血压袖带中的使用，故而所述安装部160并不是必须的。
如图3至图5所示，在其中一个实施例中，所述安装部160包括安装环162和带条164，所述带条164一端连接于所述外圈部120，且另一端连接于所述安装环162，所述安装环162套设于血压袖带气插头200。安装环162通过带条164与外圈部120连接，所述安装环162直接套设于气插头200上，且位于气插头200的凸台260下方并与凸台260下表面贴合，气插头200插入血压袖带的导气管300时，安装环162位于血压袖带的导气管300与气插头200的凸台260之间，并亦与血压袖带的导气管300端面紧密贴合，安装环162不会从气插头200上滑落，且又便于将安装环162从气插头200上取下。当血压袖带端盖100密封于气插头200开口时，外圈部120恰好贴合于凸台260的上表面，密封效果好。另外，血压袖带端盖100的安装环162还可以直接安装在导气管300上或者直接安装在气插头200上，也可以使血压袖带端盖100与导气管300或者气插头200一体成型，省去安装环162。
在其它实施例中，所述安装部160也可以通过链条或者其他方式连接外圈部120与气插头200；或者也可以将所述安装环162套设于血压袖带的导气管300上，以与外圈部120连接。
应当理解的是，所述安装部160与所述外圈部120也可以均为单独的一个部件，当需要将安装部160与外圈部120连接为一起使用时，可以通过按扣或者其他可分离的连接方式连接为一起使用。
本实施例中，所述外圈部120和所述内塞140一体成型。外圈部120与内塞140可以采用注塑成型的方式等一体成型。外圈部120与内塞140一体成型的设置使得血压袖带的密封性会更好，更加便于血压袖带的使用；且制造加工程序更加简单，节约成本。在其它的实施例中，外圈部120与内塞140也可以通过粘接等其它方式连接。
本实施例中，所述血压袖带端盖100为软胶类高分子材料式端盖。血压袖带端盖100可以采用注塑成型等工艺。软胶类高分子材料式端盖集有机物与无机物的功能于一身，有很好的耐温性、耐候性以及生理惰性等多方面良好的性能。不会对气插头200造成不良影响，进一步提高血压袖带的使用寿命。
如图4和图5所示，一种血压袖带400，包括导气管300、气插头200和如上所述的血压袖带端盖100。气插头200一端插入所述导气管300，另一端可通过所述血压袖带端盖100密封。血压袖带端盖100可分离地密封于所述气插头200开口。所述气插头200包括气插头内壁240和气插头外壁220，所述血压袖带端盖100嵌设于所述气插头内壁240和/或夹紧于所述气插头外壁220，使气插头200开口处进行密封，从而不仅能够阻止粉尘等细小颗粒通过气插头200进入血压袖带400内部而造成测量放气时气路堵塞，而且在血压袖带400清洗或消毒时，阻止清洗消毒液体进入血压袖带400内部，防止测量放气时腐蚀液体造成气路部件的腐蚀生锈，从而提高了血压测量设备的使用寿命。
如图4和图6所示，在其中一个实施例中，所述气插头200外缘中部环向凹设有气密槽280。由于所述血压袖带端盖100的外圈部120为柔性部件，气插头200插入外圈部120的内孔122时，外圈部120受挤压而变形撑大，并产生复位弹力。插入后，所述外圈部120在所述气密槽280的设置位置，在所述复位弹力作用下收缩，一方面起到更好的密封效果，另一方面亦增大了气插头200与外圈部120内壁的接触摩擦力，使所述血压袖带端盖100更稳定地密封于气插头200。当然，应当理解的是，即使不开设所述气密槽280，亦不影响所述外圈部120对气插头200的罩覆密封目的，故而所述气密槽280的开设不是必须的。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
