Description

一种升降平衡控制装置及乳腺超声成像系统 技术领域
本申请涉及医疗器械技术领域，具体涉及一种升降平衡控制装置及乳腺超声成像系统。
背景技术
乳腺超声成像系统上具有检测设备，检测设备包括探头盒及悬臂等结构，检测设备约30kg，在使用过程中，检测设备中的探头盒需要能灵活地升降至需要的高度及锁定在该位置。
常规的方案是通过电机直接驱动检测设备升降移动，电机需要克服约30kg的重量，电机需要的功率很大，对电机体积、占用空间、成本、散热、噪音等都很不利。同时电机自身的保持力矩难以完全可靠地将检测设备锁定在指定位置，需要附加锁定的机构；锁定机构一旦失效，检测设备会急剧下落，存在很大安全风险。
此外，操作者需要手动(此时电机不工作)大幅度调整检测设备的高度，需要克服约30kg的重量，将非常费力，甚至无法操作。
发明内容
一种实施例中提供一种升降平衡控制装置,包括：
至少两个转轮；
升降带，升降带安装在转轮上，升降带具有两处升降方向相反的升降段，传动带的一处升降段与乳腺超声成像系统的检测设备连接；
配重块，配重块安装在升降带的另一处升降段上；
驱动件，驱动件与至少一个转轮连接，用于驱动转轮旋转带动升降带升降移动。
一种实施例中提供一种乳腺超声成像系统，包括检测设备，检测设备包括悬臂和探头盒，还包括上述的升降平衡控制装置。
依据上述实施例的升降平衡控制装置及乳腺超声成像系统，由于在同步带的两侧分别安装有配重块和检测设备，在配重块平衡的基础上，电机仅需输出较小的功率便可驱动检测设备稳定的升降，从而可选择功率较小的电机，减小了电机的体积、占用空间、成本、散热和噪音等。配重块的设置，也使得手动调节检测设备大幅升降更为省力。并且电机 输出较小的功率也能够将检测设备锁定在一个高度位置，不需要额外附加的锁定装置，简化了结构，并降低了成本，也避免了检测设备急剧下落的安全风险。

具体实施方式
在本发明实施例中提供了一种升降平衡控制装置，通过配重块平衡乳腺超声成像系统的检测设备，以使得驱动件只需提供较小的驱动力便能够驱动乳腺超声成像系统的检测设备升降移动和锁定在一个位置上，并且能够避免乳腺超声成像系统的检测设备的急剧下落的安全风险，保证了乳腺超声成像系统的检测设备的安全检测。
如图1所示，一个实施例中，提供了一种升降平衡控制装置，本升降平衡控制装置主要包括转轮101、升降带102、配重块103和驱动件104。
本实施例中，转轮101为同步带轮，同步带轮具有两个，两个转轮101上下间隔开的安装在一个竖直平面内。升降带102为首尾相接闭合的同步带，同步带安装在同步带轮上，同步带轮可驱动同步带升降移动。
升降带102的两侧具有两处升降方向相反的升级段，如图1中所示的，位于右侧处的升降段与乳腺超声成像系统的检测设备210连接，检测设备210主要包括悬臂和探头盒，配重块103安装在升降带102位于左侧处的升降段上，配重块103的重量约为30kg，和检测设备210的重量基本相等，配重块103起到平衡检测设备210的作用。
在其他实施例中，转轮101具有四个，阵列安装在一个竖直平面内，升降带102安装在四个转轮101上，安装四个转轮101，可将升降带102左右两侧的升降段间隔开，以避让配重块103和检测设备210，防止两者发生碰撞。
在其他实施例中，转轮101也可为链轮，对应的升降带102为链条带，链轮同样可驱动链条带带动检测设备210升降移动，但移动精度略 低于同步带和同步齿轮的组合。
在本实施例中，驱动件104为电机，电机具有一个，电机的输出轴与位于下方的转轮101连接，电机用于驱动转轮101的正反旋转，转轮101再带动升降带102驱动检测设备210升降移动。
在其他实施例中，电机也可设置为两个，每个电机分别与一个转轮101连接，可进一步降低电机的输出功率，上下两个转轮101同时为主动轮，检测设备210的升降移动更为稳定。
本实施例提供的升降平衡控制装置，由于在同步带的两侧分别安装有重量相等的配重块103和检测设备210，在配重块103平衡的基础上，电机仅需输出较小的功率便可驱动检测设备210稳定的升降，从而可选择功率较小的电机，减小了电机的体积、占用空间、成本、散热和噪音等。配重块的设置，也使得手动调节检测设备210大幅升降更为省力，并且，电机输出较小的功率也能够将检测设备210锁定在一个高度位置，不需要额外附加的锁定装置，简化了结构，并降低了成本，也避免了检测设备210急剧下落的安全风险。
如图2所示，一个实施例中，提供了另一种升降平衡控制装置，在上述实施例的基础上主要增加了离合器105。
如图3所示，本实施例的离合器105为电磁离合器。离合器105安装在驱动件104(电机)的输出轴与转轮101之间，离合器105主要包括主动件105a和从动件105b，主动件105a上安装有主动轴105c，从动件105b上安装有从动轴105d，电机的输出轴通过联轴器106与离合器105上的主动轴105a连接，转轮101与离合器105上的从动轴105b连接。主动件105a和从动件105b能够处于相互结合的状态或者相互分离的状态，并且能够在相互结合状态和相互分离状态之间转换。当离合器105内的主动件105a和从动件105b结合(即处于相互结合状态)时，离合器105将驱动件104输出的力矩传输至转轮101，以实现驱动升降；当离合器105内的主动件105a和从动件105b分离(即处于相互分离状态)时，驱动件104与转轮101断开，形成过载保护。
在检测设备210升降过程中，当检测设备210压到人体达到一定压力后，电磁离合器将启动过载保护功能，即电机输出的扭矩大于离合器105的额定扭矩时，电机继续转动，而离合器将分离打滑(即离合器的主动件105a和从动件105b由相互结合的状态转换为相互分离的状态)，中断电机扭矩的传递，暂停检测设备210继续升降，起到安全保护的作 用。而常规的安全保护作用，需要在检测设备210上设置压力传感器，成本高昂，而且结构上很难设计，并且由于检测设备210中的声窗是一次性耗材，更是没有较好的可行性。
在电机与转轮101之间安装离合器105，也避免电机输出轴的被动转动，避免类似“充电”的情况出现。
如图4所示，一个实施例中，提供了一种乳腺超声成像系统，本实施例的乳腺超声成像系统主要包括检测设备210和机身220，检测设备210包括悬臂211和探头盒212。悬臂211安装在机身220上，探头盒212安装在悬臂211上。
如图1或图2所示，乳腺超声成像系统的检测设备210可安装在前述实施例所述的升降平衡控制装置的升降带102上。
升降平衡控制装置上设有配重块103与检测设备210平衡，提高了检测设备210升降的稳定性。升降平衡控制装置还设有离合器105，能够起到安全保护，防止过压伤害人体及防止电机被动旋转。
本实施例提供的乳腺超声成像系统，具有较高的稳定性，结构简单，仅需较小功率的电机便可驱动检测设备210的平稳升降和锁定不动。
以上应用了具体个例对本发明进行阐述，只是用于帮助理解本发明，并不用以限制本发明。对于本领域的一般技术人员，依据本发明的思想，可以对上述具体实施方式进行变化。
