Description

一种听诊器耳塞座及与其配合的耳塞头 技术领域
本发明涉及一种医疗器械配件， 尤其涉及听诊器， 具体为是一种耳塞座、 及其使用该耳塞座的耳塞头， 以及二者的配合结构。
背景技术
听诊器是医护工作人员执行医疗工作的重要工具， 借助听诊器的扩音功 能， 使用者可以了解到求诊患者的那内脏器官的情况。 听诊器是藉由听头将 求诊者内脏的工作声音收集放大， 再经由听管、 耳塞传递至使用者的耳朵。
现有耳塞头与耳塞座及其连接连如图 1、 图 2、 图 3、 图 4所示： 耳塞座 1为一体结构， 设有一内设螺纹的通孔 14; 包括管状体 11、 圆环体 13和平截 头圆锥体 12三部分； 其中圆环体 13与平截头圆锥体 12分别位于管状体 11 两侧；
耳塞头 2为一体结构， 设有一贯通的导音腔 24， 包括球带 21和管状体 22两部分； 管状体 22—端端面位于球带 21—端的球体切平面上， 在球带 21 与管状体 22连接部设有与平截头圆锥体 12配合的平截头圆锥体 23; 使耳塞 座 1的平截头圆锥体 12被平截头圆锥体 23倒锁住。 在一定的使用周期内因 耳塞头卫生或损坏， 需经常更换耳塞头， 且更换时必须将耳塞座一并换掉， 浪费资源， 更换麻烦， 其次， 耳塞头与耳塞座搭配单调， 不够美观。
发明内容
本发明的发明目的之一是， 提供一种可永久使用， 节约成本， 且可与耳 塞头搭配色彩， 便于耳塞头固定的耳塞座。 本发明的另一发明目的是， 提供一种安装容易的， 且更换方便， ^不易脱 落的耳塞头。
本发明的目的是这样实现的： 本发明的方案之一为：
一种听诊器耳塞座， 设有一通孔， 包括管状体和底座两部分， 所述底座 设有一台阶面和底座底面， 所述管状体位于所述台阶面之上， 环管状体跟部 台阶面上设有环槽， 所述环槽的深度不小于 4mm。 一般环槽的深度在 4mm至 9腿之间， 超出此深度也可。
进一步地； 在环槽底面与所述管状体头部端面之间设有凹槽。 一般凹槽 的深度为 0. 5mm至 1画之间。
进一步地； 在所述底座底面与所述环槽底面之间设有一通孔。
本发明的另一解决方案为：
一种听诊器耳塞头， 设有一贯通的导音腔， 包括球带与耳塞头管状体两 部分； 所述耳塞头管状体根部端面位于所述球带的一球体切平面上， 其特征 在于： 在所述耳塞头管状体头部设有环状凹槽。一般环状凹槽的宽度为在 4mm 至 9mm之间。
进一步地； 在所述导音腔上设有凸肩。 所述凸肩可在管状体内壁上， 其 长度可与管状体的长度相当， 也可小于管状体的长度。 所述凸肩还可在位于 所述耳塞头管状体与所述球带的连接部。 凸肩的高度一般在 0. 5mm至 1mm之 间。
一般耳塞头上导音腔内凸肩的高度与耳塞座上凹槽的深度是适应的。 进一步地； 在所述耳塞头管状体头部端面上设有端面凸肩。 所述凸肩可 为柱状， 也可为圆锥状等退拔。 一般耳塞头上管状体头部端面上设有端面凸肩的形状与耳塞座上所述底 座底面与所述环槽底面之间通孔的形状是相适应的。
本发明具有如下优点：
1、 由于耳塞头管状体端部设有环状凹槽， 而耳塞座底部上设有环槽， 环 状凹槽与环槽配合时， 较现有技术耳塞头与耳塞座的接触面积明显增加， 从 而有效的增加了耳塞头与耳塞座的摩擦系数， 使得耳塞头与耳塞座的配合更 加牢固。
2、 由于耳塞头管状体直径小于耳塞座管状体直径， 且耳塞头为高弹性体 材料， 因而在配合过程中耳塞头管状体对耳塞座管状体产生弹性抱力， 从而 增加配合的牢固度。
3、 耳塞头与耳塞座的配合过程中， 当耳塞头的环状凹槽推进耳塞座的环 槽内时， 方式一： 空气通过环槽底面与所述管状体端面之间的凹槽排出， 再 通过旋转耳塞头使导音腔内的凸肩落入凹槽中从而阻断空气的回流； 方式二： 空气通过底座底面与所述环槽的底面之间的通孔排出， 转动耳塞头使耳塞头 管状体端面上的凸肩与底座上的通孔配合， 从而阻断空气的回流。 从而在耳 塞头与耳塞座的配合中形成真空负压， 有效地增加了耳塞头对耳塞座的吸附 力， 使得耳塞头与耳塞座的配合更加牢固。
通过测试证明耳塞头只要可以承受 21牛顿的水平拉力约 5磅不脱落即可 保证耳塞头在正常时不会脱落
本发明的配合结构， 耳塞头在拉力测试时可以承受 25牛顿的水平拉力。 更换时通过旋转解除真空吸附力后只要用 5-6 牛顿的拉力就可以更换耳 塞头。 4、 在耳塞头与耳塞座的配合中， 耳塞座与耳塞头部件均可直观的看见， 因此可以对耳塞座和耳塞头进行两种颜色搭配来增加耳塞的整体美观度。 附图说明

实施例 5: 结合图 13可知， 同实施例 4， 在耳塞头管状体 22的头部 B' 端面 26上还设有端面凸肩 28。 端面凸肩 28可以为柱状或圆锥状等。 端面凸 肩 28的高度可在 1mm至 3mm之间。
实施例 6: 结合图 10、 图 11、 图 12可知， 同实施例 4， 在导音腔 24上 还设有凸肩 27。
在管状体 22内壁上设有凸肩 27; 凸肩 27可位于管状体 11的内壁上； 如 图 11所示， 凸肩 27位于耳塞头管状体 22与球带 21的连接部； 或如图 10所 示， 凸肩 27可位于耳塞头管状体 22根部 A'球带 21上； 或如图 12所示， 凸 肩 27可位于耳塞头管状体 22根部 A'球带 21上至管状体 22的头部 B'端面 26 之间。
凸肩 27的长度可以与管状体 22的长度相同，也可小于管状体 22的长度。 在管状体 22与所述球带 21的连接部设有凸肩 27。
实施例 7: 结合图 5和图 9以及图 23对本发明做进一步的说明。
听诊器耳塞头与耳塞座的配合结构， 包括耳塞头 2和耳塞座 1， 其中： 听诊器耳塞头 2， 设有一贯通的导音腔 24， 包括球带 21与耳塞头管状体 22两部分； 耳塞头管状体 22跟部端面位于球带 21的一球体切平面上， 耳塞 头管状体 22头部 B'设有宽度为 7mm的环状凹槽 25;
听诊器耳塞座 1， 设有通孔 14， 由底座 18和管状体 11组成； 其中， 底 座 18包括台阶面 16和底座底面 15， 管状体 11一端面位于台阶面 16上， 环 管状体 11根部的台阶面 16上设有环槽 17， 环槽 17的深度为 7mm;
耳塞头管状体 22套于管状体 U外， 且耳塞头管状体 22的内径与管状体 11的外径相匹配。 当管状体 11推进耳塞头管状体 22后， 使环槽 17与环状凹 槽 25相配合， 环槽 17的深度与环状凹槽 25的深度相当， 均为 7mm。 当管状 体 11推进耳塞头管状体 22至管状体 11端面 26抵触环槽底面 110时， 耳塞 头与耳塞座的配合完毕。
实施 8: 结合图 14、 图 15、 图 16、 图 17、 图 18、 图 19对本发明做进一 步的说明
其余与同实施 7， 在环槽底面 110与管状体头部端面 111之间设有凹槽 19， 凹槽 19的深度为 0. 5mm; 在导音腔 24上设有凸肩 27; 凸肩 27的高度为 0. 5醒； 凹槽 19的深度与凸肩 27的高度相适应。
转动耳塞头 2，使凸肩 27与凹槽 19配合，最终使凸肩 27嵌入凹槽 19内， 从而阻断空气回流， 从而在耳塞头 2与耳塞座 1的配合形成真空负压， 有效 地增加了耳塞头 2对耳塞座 1的吸附力， 使得耳塞头 2与耳塞座 1的配合更 加牢固。
其中，凹槽 19的深度可以为 0. 5腿至 1mm间的任意深度，如 0. 5腿、 0. 6mm、 0. 7醒、 0. 8醒、 0. 9腿或 1mm等； 而凸肩 27的高度也可 0. 5mm至 1mm间的任 意高度， 如 0. 5mm、 0. 6mm, 0. 7mm、 0. 8mm、 0. 9腿或 lmm等。 其中， 凸肩 27可位于管状体 11的内壁上； 也可位于耳塞头管状体 22与 球带 21的连接部， 或位于耳塞头管状体 22根部 A'球带 21上， 或位于耳塞头 管状体 22根部 A'球带 21上至端面 26之间。 凸肩 27的长度可以与管状体 11 的长度相当， 也可小于管状体 11的长度等。
一般凸肩 21的位置位于耳塞头管状体 22与球带 21的连接部， 或位于耳 塞头管状体 22根部 A'球带 21上， 或位于管状体 11的根部 A'且长度远小于 管状体 11的长度较好。
若凸肩 27位于管状体 11的头部 B'或位于耳塞头管状体 22根部 A'球带 21上至端面 26之间 （如图 17、 图 18、 图 19)， 当管状体 11推进耳塞头管状 体 22内时： 1 ) 若一开始， 凸肩 27即嵌入凹槽 19内， 在管状体 11推进耳塞 头管状体 22的过程中， 由于凸肩 27阻断了空气的回流， 随着管状体 11的推 进， 凹槽 19内的气压越来越大， 使管状体 11的推进较费劲， 不便于安装； 2 ) 自管状体 11推进耳塞头管状体 22的过程中， 至端面 26与环槽底面 110相抵 触时， 此安装过程也相当困难， 因耳塞头管状体 22的外径与管状体 11的内 径相匹配， 而凸肩 27无疑成为管状体 11推进的阻力。
当凸肩 27位于耳塞头管状体 22与球带 21的连接部， 或位于耳塞头管状 体 22根部 A'球带 21上， 或位于管状体 11的根部 A'， 在管状体 11的推进过 程的初期及中期， 凸肩 27均不能构成对管状体 11的推进阻力。 仅至管状体 11的推进的尾声时， 凸肩 27才构成阻力， 但因凸肩 27长度较短如在 lmm至 2皿之间， 管状体 11推进的阻力可忽略， 故安装比较容易。
实施例 9: 结合图 20、 图 21及图 22对本发明做进一步的说明。
听诊器耳塞头与耳塞座的配合结构， 包括耳塞头 2和耳塞座 1， 其中： 听诊器耳塞头 2， 设有一贯通的导音腔 24， 包括球带 21与耳塞头管状体 22两部分； 耳塞头管状体 22跟部端面位于球带 21的一球体切平面上， 耳塞 头管状体 22头部 B'设有宽度为 6mm的环状凹槽 25; 耳塞头管状体 22头部端 面 111上设有端面凸肩 28， 端面凸肩 28可以为圆柱型或圆锥状， 端面凸肩 28的高度为 lmm至 2膽之间。
听诊器耳塞座 1， 设有通孔 14， 由底座 18和管状体 11组成； 其中， 底 座 18包括台阶面 16和底座底面 15， 管状体 11一端面位于台阶面 16上， 环 管状体 11根部的台阶面 16上设有环槽 17， 环槽 17的深度为 6mm; 在底座底 面 18与环槽底面 110之间设有一通孔 3， 通孔 3可以为圆柱型或圆锥状等形 状；
耳塞头管状体 22套于管状体 11夕卜， 且耳塞头管状体 22的外径与管状体 11 的内径相匹配。环槽 17与环状凹槽 25相配合， 环槽 17的深度与环状凹槽 25 的深度相对， 均为 6mm。 管状体 11推进耳塞头管状体 22过程中， 在耳塞头 2 的头部 B'的端面 26与耳塞座 1的环槽底面 110之间的空气通过通孔 3排除， 当耳塞头 2的头部 B'的端面 26抵触耳塞座 1的环槽底面 110后，转动耳塞头 管状体 22， 使端面凸肩 28塞进通孔 3从而阻断空气的回流， 耳塞头 2与耳塞 座 1的配合形成真空负压， 有效地增加了耳塞头 2对耳塞座 1的吸附力， 使 得耳塞头 2与耳塞座 1的配合更加牢固。
结合实施例 7或 8可知， 耳塞座 1的底座 18与耳塞头 2的管状体 22的根 部 A'与球带 21均为可见部分， 故可调节耳塞座 1与耳塞头 2的色彩， 使耳塞 座 1和耳塞头 1进行两种颜色搭配来增加整体美观度。
