图6为图5的剖视图。
【具体实施方式】
参考图1和图2,本发明一个实施例提供的一种医疗用蠕动泵,包括驱动器10、泵体30和软管60。
所述驱动器10包括电机12和受电机12驱动的齿轮减速机构14。
所述泵体30包括腔室32和收容于腔室32内的用于挤压软管60从而使得软管内的介质如血液流动的转子40。所述腔室32包括一圆弧形壁部34,所述软管60的一部分紧贴所述弧形壁部34的内表面,所述弧形壁部34的内表面为圆柱面的一部分,所述内表面的中心与转子40中心重合。
所述齿轮减速机构14包括支撑轴16和输出齿轮18(见图3)。一连接件70固定连接至所述输出齿轮18,所述支撑轴16贯穿所述齿轮18和连接件70从而使得所述齿轮18和连接件70可绕支撑轴16旋转。所述连接件70收容于腔室32内,所述转子40可拆卸地连接至连接件70从而通过连接件70可随输出齿轮18同步旋转,所述输出齿轮18隐藏于腔室32底板33远离转子40的一侧,即在腔室32内看不见输出齿轮18,这样既可保护输出齿轮18,又可保护用户避免其受到输出齿轮18的伤害。
请参阅图3和图4,所述连接件70包括若干与转子40卡扣的卡爪72,所述卡爪末端设倒钩74。所述转子40包括若干锁固件42,每一锁固件42上开设有卡口44用于与倒钩74卡扣。所述转子40还包括本体46,所述本体46设沿其轴向延伸的槽462以便卡爪72穿设,本体46对应锁固件42处设导槽48,锁固件42可在导槽48内滑动,锁固件42与本体46之间设弹性件如弹簧49,所述弹簧49被夹持于锁固件42与本体46之间,弹簧49受压变形产生的变形力推压所述锁固件42以保持锁固件42处于其卡口44与连接件70的倒钩74相互卡扣的位置。具体地,所述锁固件42开设有两个卡口44,每一卡口44的靠近弹簧49端的底边具有一从卡口44侧壁朝向卡口44延伸的挡板45。在外力作用下,所述锁固件42可克服弹簧49的阻力相对本体46向内或向外滑动以使得卡口44的挡板45避开连接件72的导钩74,在连接件70的倒钩74越过卡口44的挡板45后,外力移除,在弹簧49的推压作用下,锁固件42复位,所述连接件72的倒钩74压靠于卡口44的挡板45上,从而将连接件70固定至转子40以使得转子40可随连接件70一起旋转。本实施例中,弹簧49设置于本体46的中心部与锁固件42的内端部之间,弹簧49具有向外推压锁固件42的趋势,连接件70的倒钩74与卡口44的内侧壁即最靠近本体46中心的侧壁抵靠以限制锁固件42在弹簧49的推压下过份向外滑动。
优选地,连接件70包括一对卡爪72,每一卡爪72末端设有一对倒钩74,倒钩74之间的部分被切除,每一锁固件42设一对卡口44,每一对倒钩74相应地卡设于一卡口44内,此种设置可增强连接件70与转子40之间的结合强度。
所述连接件70还包括连接部76,优选地,所述连接部76为环形,中央设通孔,所述驱动器10的输出齿轮18固定安装于连接部76的远离卡爪72的一端,支撑轴16穿过输出齿轮18和连接部76从而可转动地支撑输出齿轮18和连接件70。
所述连接件70设有至少一台阶78以定位所述转子40位于腔室32内的轴向位置。本实施例中,所述连接件70的连接部76的靠近卡爪72的一端的中央设突出的台阶78,卡爪72的靠近倒钩74位置处亦设台阶78,所述台阶78与转子40本体46相抵靠(见图6),通过倒钩74与台阶78的配合可轴向限定转子40相对连接件70的位置。
请参阅图5,所述转子40还包括若干可相对本体46滑动的滑块50、装设于滑块50末端并可相对滑块50转动的滚柱52及设于本体46中央部位与滑块50内端之间的弹性件如弹簧54,所述弹簧54向外抵顶所述滑块50以使得所述滚柱52能挤压软管60。具体地,所述本体46设收容滑块50的收容空间,所述滑块50可在收容空间内滑动,滑块50设肩部56,本体46对应滑块的肩部56设弧形定位面464,所述肩部56的与本体46定位面464相抵靠的抵靠面564的形状与本体46定位面464的形状一致,所述定位面464与滑块50肩部56配合用于限制滑块50向外移动的最大距离,从而控制滚柱52的最靠外位置。优选地,本体46的若干弧形定位面464位于一同心圆上,所述同心圆以支撑轴16的中心也即转子40的中心为圆心,这样,有利于保持若干滑块50的同心度,也即保持若干不同滑块50上的滚柱52的最外边缘至转子40中心的距离一致,从而保证不同滑块50上的滚柱52挤压软管60时对软管60的挤压量保持不变,从而保持恒定的介质流量。
请参阅图2,所述软管60大致呈U型,安装于腔室32的壁部内侧。工作时,驱动器10的输出齿轮18通过连接件70驱动转子40旋转,转子40上的滚柱52沿软管60的延伸方向挤压软管60,从而推动软管60内的介质沿转子旋转方向运动。
所述转子40还包括盖板47,所述盖板47可通过固定件如螺钉等固定至本体46。盖板47的远离本体46侧设把手472,这样,在驱动器10停止工作时,用户可通过把手472推动转子40旋转。
所述泵体30还包括用于覆盖所述腔室32的盖体36,所述盖体36与腔室32可通过铰接方式旋转地连接。
优选地,所述盖体36与腔室32之间设电磁锁。
所述盖体36与腔室32其中之一安装有感应磁铁362,其中之另一安装有感应器322如霍尔感应器(hallsensor),当盖体36处于覆盖腔室32位置时,感应器322将产生一指示信号以指示盖体36处于关闭状态,当盖体36处于打开位置时,感应器322又将产生另一指示信号以指示盖体36处于打开状态。
本发明的医疗用蠕动泵尤其适合用作血泵,当用作血泵时,所述输出齿轮18的转速优选为80~120转/分。
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,如锁固件与连接件之间的可拆卸连接方式可以有多种变化,当使用卡钩与卡口配合方式,卡钩与卡口的设置位置不限,卡钩可设在锁固件与连接件其中之一,卡口可设在锁固件与连接件其中之另一;还可以使用卡钩与卡钩的卡扣连接方式,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。
