Description

一种用于医疗器械清洗设备的多位单通阀 技术领域
本发明涉及一种医疗器械清洗设备的部件，具体说是涉及一种用于医疗器械清洗设备的多位单通阀。
背景技术
超声波清洗机是目前应用十分广泛的医疗器械清洗设备，尤其是在管腔型医疗器械的清洗场合，超声波清洗机的使用非常普遍。由于管腔型医疗器械通常具有管径较小、管身较长的特点，因而医护人员一般均把管腔型医疗器械集中放置在清洗篮或清洗槽内进行超声波清洗。但是，现有管腔型医疗器械的超声波清洗机，存在着两个重大的缺陷。其一，由于清洗过程中医疗器械之间相互堆叠，使超声波辐射在传播时不断被医疗器械的管壁吸收。随着离超声波换能器的距离逐渐增大，超声波的震荡频率逐步减弱，从而导致其对管腔型医疗器械的清洗效果下降。其二，附在管腔型医疗器械上污垢的粘结力各不相同，特别是在管腔内，由于受表面张力和污垢自身重力的作用，使污垢在管腔内壁的粘结力大幅增加。把管腔型医疗器械集中放置清洗难以保障管腔内的污垢能在超声波震荡的作用下完全脱落，特别是针对一些粘结力较大、需要进行抽吸清洗的医疗器械管腔，集中清洗很难满足完全清理管腔内污垢的要求。事实上，由于超声波震荡在传播过程中不断被吸收，到达管腔内的超声波振幅将大大降低，其清洗能力也将大幅下降。
针对集中放置清洗的缺陷，本领域技术人员也在不断改进管腔型医疗器械的超声波清洗设备，并开发出管腔内灌流清洗技术。如中国专利ZL 201520315754.6公开了一种腹腔镜超声波清洗机。其利用设置于箱体内的灌流泵和连接于腹腔镜上的灌流接头配合使用，将槽体内的清洗液抽送至腹腔镜的管腔内，实现对管腔内部的清洗。然而，上述灌流泵和灌流接头组合的灌流机构中，灌流泵与若干个灌流接头同时接通。当灌流泵进行供液时，受多个灌流接头的分流作用影响，大大降低了灌流接头的输出压力。此外，灌流泵对清洗液仅仅起到传输推动的作用。清洗液在管腔内部传输过程中，其液体压力不断被管腔内污垢吸收而降低，导致清洗液在管腔内对污垢的推动作用逐步减弱，从而使管腔末端的清洗效果大幅下降。因此，上述腹腔镜超声波清洗机仍然未能对管腔内的污垢进行彻底清洗。
发明内容
本发明的目的在于克服现有技术存在的上述不足，提供一种可保障管腔内压力稳定、 清洗效果好、自动化程度高的用于医疗器械清洗设备的多位单通阀，适用于超声波清洗机及其他清洗管腔类医疗器械的清洗设备。

进一步说，电机的转轴上设有传动组件，光电分度器和阀体组件设于传动组件上。
更进一步说，传动组件包括设于电机转轴上的联轴器、设于联轴器上并穿接于光电分度器上的传动轴，传动轴固定在阀体组件上。
更进一步说，光电分度器包括设于阀体安装座上的光电感应管和设于传动轴上的光栅盘，光栅盘与光电感应管位置相对应，光电感应管与电机电连接。
根据上述结构进行优化，传动轴上设有与光栅盘连接的定位器。
根据上述结构进行优化，阀体安装座和光电感应管之间设有固定板。
根据上述结构进行优化，光电分度器上设有电路板保护壳。
更进一步说，液流转接组件包括设于阀体安装座上的液流转接板，液流转接板上设有连接于吸液泵上的出水口和至少三个与出水口连通的进水口。
根据上述结构进行优化，液流转接板上设有十二个进水口。
根据上述结构进行优化，液流转接板上设有可供传动轴穿过的通孔。
根据上述结构进行优化，液流转接板上设有密封压板。
更进一步说，阀体组件包括设于阀体安装座上的阀壳和设于传动轴上的阀芯。
根据上述结构进行优化，阀壳上设有至少三个与进水口位置相对应的导流孔。
根据上述结构进行优化，阀壳上设有十二个导流孔。
根据上述结构进行优化，阀芯包括固定在传动轴上的安装板、设于安装板上的销轴及设于销轴上的活动滚子，活动滚子外沿与阀壳内腔匹配连接。
根据上述结构进行优化，安装板的两侧设有封闭板，活动滚子设于安装板和封闭板之间，封闭板和安装板上均设有位置相对应并可供一根导液管通过的凹槽。
根据上述结构进行优化，阀壳外设有盖板，盖板上设有与导流孔位置相对应的导液孔。
根据上述结构进行优化，盖板上设有可穿接传动轴的定位孔，定位孔上设有可随传动轴旋转的指针。
根据上述结构进行优化，盖板内侧设有套接在传动轴上的轴套。
根据上述结构进行优化，阀壳和阀体安装座之间设有阀体安装加强条。
本发明对现有技术的超声波清洗机进行改进，加入了用于医疗器械清洗设备的多位单通阀，其优点如下：
1、本发明的用于医疗器械清洗设备的多位单通阀结构中，在阀体安装座上依次设置电机、光电分度器、液流转接组件和阀体组件。通过电机的驱动，使光电分度器和阀体组件随之转动，并结合与吸液泵连通的液流转接组件，实现光电分度控制的步进式依次吸液。上述单通阀结构除了可大大提高超声波对管腔内部清洗的稳定性及改善其清洗效果外，还真正实现了内部清洗的全自动化控制。
2、本发明的用于医疗器械清洗设备的多位单通阀结构中，电机的转轴上设置传动组件，光电分度器和阀体组件设于传动组件上，传动组件可根据电机转轴的旋转对光电分度器和阀体组件的转动起传导作用。同时，传动组件包括设于电机转轴上的联轴器、设于联轴器上并穿接于光电分度器上的传动轴，传动轴固定在阀体组件上，该结构可保障光电分度器和阀体组件旋转的稳定性及可靠性。
3、本发明的用于医疗器械清洗设备的多位单通阀结构中，光电分度器包括设置在阀体安装座上的光电感应管和设置在传动轴上的光栅盘，光栅盘与光电感应管位置相对应，且光电感应管与电机电连接。通过光栅盘和光电感应管的配合使用，在电机旋转时，可根据光电感应管的通断控制电机电源的通断，对传动组件旋转进行分度控制，该结构可真正实现传动组件带动阀体组件的步进旋转，从而提升吸液泵的吸液作用，改善超声波的清洗效果。
4、本发明的用于医疗器械清洗设备的多位单通阀结构中，液流转接组件包括设于阀体安装座上的液流转接板，液流转接板上设有连接于吸液泵上的出水口和至少三个与出水口连通的进水口。在光电分度器和阀体组件的配合使用下，传动轴以分度步进的方式旋转，使液流转接板上的进水口同样可以步进打开、关闭，实现单个管路接通、其余管路封闭的效果。所以吸液泵的产生的吸力可避免分流作用的影响，完全作用于接通的管路，从根本上保障了清洗液在管腔内部压力的稳定性。此外，由于在出水口处利用了吸液泵的抽吸作用，随着清洗液深入管腔，其所受吸引力逐渐加大，其抽吸压力不受管腔内壁污垢的吸收影响，提高了管腔内清洗液压力的稳定性，有效改善了超声波清洗的效果。
5、本发明的用于医疗器械清洗设备的多位单通阀结构中，阀体组件包括设于阀体安装座上的阀壳和设于传动轴上的阀芯，而阀芯包括固定在传动轴上的安装板、设于安装板上的销轴及设于销轴上的活动滚子，活动滚子外沿与阀壳内腔匹配连接。并且，安装板上设 有可供一根导液管通过的凹槽。在安装板随着传动轴旋转的过程中，利用活动滚子和阀壳之间的匹配连接的密封作用和凹槽对导液管的连通作用，使活动滚子和安装板在传动轴旋转时分别对进水口上的管路进行依次封闭和依次打开。当活动滚子和安装板的密封段旋转至导液管上时，其对导液管起封闭作用；当活动滚子的间隙和凹槽旋转至导液管上时，其对导液管起连通作用。通过上述旋转导通机构，实现了出水口和进水口的单独通路，避免出现吸液泵在工作时因多管路连通而导致管腔内液体压力损失较大的问题。另外，由于在一根导液管连通出水口时，其他导液管处于密封状态，所以提高了超声波清洗机内部的液体压力，进而提高了导通的进水口的液体压力，实现清洗液在管腔内部快速流动，改善了其清洗的效果。

具体实施方式
下面结合附图对本发明作进一步的描述。
根据附图1至附图9所示，本发明的用于医疗器械清洗设备的多位单通阀主要包括阀体安装座1和阀体组件2。其中，阀体安装座1固定在超声波清洗机上；而阀体组件2则设于阀体安装座1上。阀体安装座1上依次设有电机3、光电分度器6、液流转接组件4和阀体组件2，液流转接组件4与吸液泵连通。利用电机3带动光电分度器6和阀体组件2转动， 并与吸液泵连通的液流转接组件4配合使用，实现流经管腔型医疗器械的清洗液的光电分度控制的步进式依次抽吸。而电机3的转轴上设有传动组件5，光电分度器6和阀体组件2设于传动组件5上。该传动组件5包括联轴器51和传动轴52，其中联轴器51设于电机3的转轴上；而传动轴52则设于联轴器51上，并且其穿接于光电分度器6上。另外，传动轴52固定在阀体组件2上。上述连接机构可确保电机3通过联轴器51实时驱动传动轴52旋转，并且带动光电分度器6和阀体组件2转动，改善阀体组件2和光电分度器6动作的稳定性和可靠性。
本发明的光电分度器6主要包括光电感应管61和光栅盘62。其中光电感应管61设于阀体安装座1上；而光栅盘62则设于传动轴52上，并且光栅盘62与光电感应管61位置相对应，光电感应管61与电机3电连接。通过光电感应管61在光栅盘62转动时产生的光电感应作用，真正实现了可根据光栅盘62的旋转角度控制电机3电源的通断，从而保障了步进式依次抽吸的稳定性。为了使光栅盘62和传动轴52的连接更稳固，传动轴52上设有与光栅盘62连接的定位器63。而在阀体安装座1和光电感应管61之间设有固定板64，固定板64可把光电感应管61固定在阀体安装座1上，保障光电感应管61和光栅盘62的位置始终处于相对应的状态，避免光电感应管61因超声波清洗机工作时产生振动而出现移位的现象。此外，光电分度器6上设有电路板保护壳65，电路板保护壳65可防止外界的液体进入光电感应管61的控制电路中，起阻隔外界干扰的作用。
本发明的液流转接组件4主要包括液流转接板41、进水口43和出水口42。液流转接板41设置在阀体安装座1上，进水口43和出水口42均设置在液流转接板41上，出水口42可与外界的吸液泵连通。首先，为了使进液和出液更顺畅，进水口43可设置在传动轴52的轴线方向上，而出水口42则设在液流转接板41的侧面上。其次，出水口42与吸液泵连通，利用对清洗液的抽吸力代替传统的推动力，随着清洗液深入管腔，其所受吸引力逐渐加大，其抽吸压力不受管腔内壁污垢的吸收影响。进水口43的数量至少为三个，通过光电分度器6的控制，使进水口43始终只有一个与出水口42连通，从而避免了进水口43因分流作用而造成管腔内压力大幅下降。事实上，本发明中的液流转接板41上可设置十二个或二十个进水口43，随着进水口43的数量增加，管腔型医疗器械的一次清洗数量也就越多。为了使进水口43的封闭、打开可以严格按照光电分度器6的步进旋转实施，进水口43可均匀分布在液流转接板41上。另外，液流转接板41上设有可供传动轴52穿过的通孔44，通孔44的作用是使传动轴52可穿过液流转接板41而连接至阀体组件2上，而液流转接板41的内腔与通孔44之间可通过液流转接板41上设置的密封压板45进行密封，该结构能有 效防止清洗液在工作时渗漏至传动轴52上。
本发明的阀体组件2主要包括阀壳21和阀芯22，其中阀壳21设于阀体安装座1上，而阀芯22则设于传动轴52上。与液流转接板41对应，阀壳21上同样设有至少三个导流孔211，导流孔211的位置与进水口43相对应。导流孔211除了对通有清洗液的导液管具有定位作用外，其还保证了导液管在阀体组件2旋转过程中始终与进水口43处于一一对应的状态，避免因阀体组件2旋转而出现管路扭曲打结的情况。导流孔211的数量同样可设置为十二个或二十个，其同样可以均匀分布在阀壳21与液流转接板41对应的表面上。阀芯22包括安装板221、销轴222及活动滚子223，其中安装板221固定在传动轴52上，而销轴222设于安装板221上，活动滚子223则设于销轴222上，并可绕销轴222旋转，活动滚子223外沿与阀壳21内腔匹配连接。本发明的阀芯22中，活动滚子223可以设为至少两个，因而活动滚子223之间具有可通过导液管的间隙，以实现随着活动滚子223的转动而对导液管进行步进式打开、关闭。另外，安装板221的两侧设有封闭板224，活动滚子223设于安装板221和封闭板224之间，封闭板224和安装板221上均设有凹槽225，凹槽225之间位置相对应，并且其可供一根导液管通过。封闭板224的作用是对活动滚子223的转轴两侧均起定位作用，保障活动滚子223在工作时的始终处于稳定状态。凹槽225则是保证导液管在活动滚子223旋转时的顺利导通，以确保吸液泵对清洗液抽吸的稳定性。此外，为了使活动滚子223旋转时导液管能完全导通，活动滚子223的间隙位置可与凹槽225相对应。
本发明的阀壳21外侧还可以设置盖板23，而盖板23上设有与导流孔211位置相对应的导液孔231，导液孔231可把导液管经导流孔211连接至进水口43上。盖板23上设有可穿接传动轴52的定位孔232，定位孔232上设有可随传动轴52旋转的指针233，指针233可指出与出水口42连通的导液管，令使用者可方便的了解吸液泵的连通状态。盖板23内侧设有套接在传动轴52上的轴套234，轴套234可改善传动轴52与盖板23的连接稳定性，减少因传动轴52上部件较多而容易出现振动的现象。为了使阀体组件2的安装更稳固，阀壳21和阀体安装座1之间可设置阀体安装加强条24，阀壳21固定在安装加强条上。
本发明的用于医疗器械清洗设备的多位单通阀安装后，清洗篮或清洗腔的清洗液通过管腔接头和导液管传输，并经过导液孔231和导流孔211后连接至进水口43上。出水口42上连接有吸液泵，通过吸液泵的抽吸作用，可把清洗液抽出。用于医疗器械清洗设备的多位单通阀工作时，接通电机3电源，电机3带动传动组件5、光栅盘62和阀芯22旋转。当光栅盘62触发光电感应管61作用时，电机3停止工作，此时其中一根导液管处于活动滚 子223的间隙和凹槽225处，因而处于导通状态，其他导液管受活动滚子223外沿与阀壳21内腔的挤压而封闭，实现导液管的单独通路，出水口42上的吸液泵则对通路的导液管起抽吸作用。随着光栅盘62的转动，导液管依次导通，也依次关闭，从而实现吸液泵对导液管的依次抽吸。
上述具体实施例仅为本发明效果较好的具体实施方式，凡与本发明的用于医疗器械清洗设备的多位单通阀相同或等同的结构，均在本发明的保护范围内。
