Description

用于肺功能测试的吹嘴装置 技术领域
本发明属于医疗器械技术领域，具体地讲，涉及一种用于肺功能测试的吹嘴装置。
背景技术
肺功能检查是呼吸系统疾病的必要检查项目之一，对于早期检出肺、气道病变，评估疾病的病情严重程度及预后，评定药物或其它治疗方法的疗效，鉴别呼吸困难的原因，诊断病变部位、评估肺功能对手术的耐受力或劳动强度耐受力及对危重病人的监护等方面都有重要的指导意义。医院病人测试肺功能吹嘴装置是检查肺功能的必备耗材，然而现有的肺功能测试的吹嘴装置存在病人含口嘴不紧、测试过程中有漏气的问题，继而导致肺功能测试指标不准和病人吹气吸气困难，这将导致医生给病人的诊断有误。
发明内容
为解决上述现有技术存在的问题，本发明提供了一种用于肺功能测试的吹嘴装置，该吹嘴装置可以使待测试人员有效做出呼气、吸气的动作，尽量做到最大可能的吸入气体，再用最大的力量和最快的速度呼出体内气体输入到检测设备中。
为了达到上述目的，本发明采用了如下的技术方案：
一种用于肺功能测试的吹嘴装置，该吹嘴装置包括相互流体连通的设备连接部和吹嘴连接部；其中，所述设备连接部具有圆柱状腔体，所述吹嘴连接部具有两端呈截面球体状腔体；所述设备连接部的一端用于连接至肺功能测试设备，另一端与所述吹嘴连接部连接，所述吹嘴连接部的另一端设置有一吹嘴平面，所述吹嘴平面的形状为圆形，所述吹嘴平面上设置有一吹嘴口；其中，所述圆柱状腔体的直径小于所述球体状腔体的直径。
进一步地，所述设备连接部的长度为5cm～7cm，所述吹嘴连接部的长度为2cm～3cm。
进一步地，所述圆柱状腔体的直径为2cm～3cm，所述球体状腔体的直径为2.5cm～4cm，所述吹嘴平面的直径为2cm～3cm。
进一步地，所述吹嘴平面的直径与所述圆柱状腔体的直径相等。
进一步地，所述吹嘴口的形状为圆形，其直径略小于所述吹嘴平面的直径。
进一步地，所述吹嘴口呈“十”形形状；其中，所述“十”形吹嘴口的宽度为0.1cm～2cm。
进一步地，所述吹嘴口呈四角星形形状；其中，所述四角星形吹嘴口的最宽处的宽度为0.1cm～2cm。
进一步地，所述吹嘴口呈方形形状；其中，所述方形吹嘴口的长和宽均小于所述圆柱状腔体的直径。
进一步地，该吹嘴装置为一体成型的结构。
本发明的有益效果在于：该装置中的吹嘴连接部具有球体状腔体，并且球体状腔体的直径大于设备连接部中圆柱状腔体的直径，对待测试人员呼出的气体进行短暂的存放，从而使待测试人员呼出的气体均能传递至肺功能测试设备中进行检测，因此使待测试人员可以用最大的力量和最快的速度呼出体内气体输入到检测设备中并且不发生漏气，提高测试结构的准确度。
附图说明
通过结合附图进行的以下描述，本发明的实施例的上述和其它方面、特点和优点将变得更加清楚，附图中：
图1是本发明实施例提供的用于肺功能测试的吹嘴装置的结构示意图；
图2是本发明实施例1的吹嘴口的结构示意图；
图3是本发明实施例1的另一种吹嘴口的结构示意图；
图4是本发明实施例2的吹嘴口的结构示意图；
图5是本发明实施例3的吹嘴口的结构示意图。
具体实施方式
以下，将参照附图来详细描述本发明的实施例。然而，可以以许多不同的形式来实施本发明，并且本发明不应该被解释为限制于这里阐述的具体实施例。 相反，提供这些实施例是为了解释本发明的原理及其实际应用，从而使本领域的其他技术人员能够理解本发明的各种实施例和适合于特定预期应用的各种修改。在附图中，为了清楚起见，可以夸大元件的形状和尺寸，并且相同的标号将始终被用于表示相同或相似的元件。
实施例1
图1是根据本发明的实施例1的用于肺功能测试的吹嘴装置的结构示意图。参照图1和图2，该吹嘴装置包括相互流体连通的设备连接部10和吹嘴连接部20，其中，设备连接部10具有圆柱状腔体101，吹嘴连接部20具有两端呈截面的球体状腔体201。所述设备连接部10的一端用于连接至肺功能测试设备(附图中未示出)，另一端与所述吹嘴连接部20连接，所述吹嘴连接部20的另一端设置有一吹嘴平面202，所述吹嘴平面202的形状为圆形，所述吹嘴平面202上设置有一吹嘴口203；其中，所述圆柱状腔体101的直径d1小于所述球体状腔体201的直径d2。
具体地，所述设备连接部10的长度L1可以选择为5cm～7cm，所述吹嘴连接部20的长度L2可以选择为2cm～3cm。所述设备连接部10中的圆柱状腔体101的直径d1可以选择为2cm～3cm，所述吹嘴连接部20中的球体状腔体201的直径d2可以选择为2.5cm～4cm，其中吹嘴平面202的直径d3可以为2cm～3cm。在本实施例中，装置连接部10的长度L1为5cm，而嘴对接部20的长度L2为2cm；圆柱状腔体101的直径d1为2cm，球体状腔体201的直径d2为2.5cm，吹嘴平面202的直径d3为2cm(吹嘴平面202的直径d3最好设置为与圆柱状腔体101的直径d1相等)。
如图2所示，在本实施例中，设置在吹嘴平面202上的吹嘴口203的形状为圆形，其直径略小于所述吹嘴平面的直径d3。在本实施例中，吹嘴口203的形状也可以设计为方形形状，如图3所示，其宽度和长度均应小于圆柱状腔体101的直径d1(本实施例中，吹嘴平面202的直径d3与圆柱状腔体101的直径d1相等)。
进一步地，该吹嘴装置为一体成型的结构。并且，为了保证待测试人员良好的测试体验，该吹嘴装置的材质为塑料；但本发明并不限制于此，其他如较为质地坚硬的纸、或金属材质均可。
直径或宽度约为2cm～3cm的圆形或方形吹嘴口202可恰好与待测试人员的嘴部相吻合，如此吹嘴口202的边沿卡设在待测试人员的嘴部周围，在测试 的过程中，可有效地防止因吹嘴与待测试人员脸部贴合不严密而造成的漏气问题。
与此同时，该装置中的吹嘴连接部20具有球体状腔体201，并且球体状腔体201的直径大于设备连接部10中圆柱状腔体101的直径，可在一定程度上将经由待测试人员呼出的气体进行短暂的存储，继而经由设备连接部10传递至肺功能测试设备中进行测试，从而避免了某些肺活量大的待测试人员在吹气时因感到吹嘴空间有限而无法完全呼出造成的测试不准的问题。
实施例2
在实施例2的描述中，与实施例1的相同之处在此不再赘述，只描述与实施例1的不同之处。实施例2与实施例1的不同之处在于设置在吹嘴平面202上的吹嘴口203的形状不同。如图4所示，本实施例中吹嘴口203呈“十”形形状；其中，该“十”形吹嘴口203的宽度L3为0.5cm。一般地，此中间开口处的宽度L3控制为0.1cm～2cm即可。
在本实施例中，当待测试人员的嘴部贴紧上述吹嘴口203时，“十”形吹嘴口203周边形成阻挡部贴合在嘴部周围的脸颊上，防止已经吹入球体状腔体201的气体泄漏出，从而进一步保证所述吹嘴装置的密封性，以防止在测试过程中出现漏气现象。
实施例3
在实施例3的描述中，与实施例1的相同之处在此不再赘述，只描述与实施例1的不同之处。实施例3与实施例1的不同之处在于设置在吹嘴平面202上的吹嘴口203的形状不同。如图5所示，本实施例中吹嘴口203呈四角星形形状，该四角星形吹嘴口203的最宽处的宽度L5为0.5cm。一般地，此中间开口处的最宽处的宽度L5控制为0.1cm～2cm即可。
在本实施例中，当待测试人员的嘴部贴紧上述吹嘴口203时，四角星形吹嘴口203周边形成阻挡部贴合在嘴部周围的脸颊上，防止已经吹入球体状腔体201的气体泄漏出，从而进一步保证所述吹嘴装置的密封性，以防止在测试过程中出现漏气现象。
综上所述，上述实施例提供的用于肺功能测试的吹嘴装置，其中的吹嘴连接部具有球体状腔体，并且球体状腔体的直径大于设备连接部中圆柱状腔体的直径，对待测试人员呼出的气体进行短暂的存放，从而使待测试人员呼出的气 体均能传递至肺功能测试设备中进行检测，因此使待测试人员可以用最大的力量和最快的速度呼出体内气体输入到检测设备中并且不发生漏气，提高测试结构的准确度。
虽然已经参照特定实施例示出并描述了本发明，但是本领域的技术人员将理解：在不脱离由权利要求及其等同物限定的本发明的精神和范围的情况下，可在此进行形式和细节上的各种变化。
