Description

一种医用充压控制装置 技术领域
本发明涉及医疗器材领域，特别是一种医用充压控制装置。
背景技术
医用球囊压力泵适用于球囊扩张导管，对球囊进行充盈和收缩处理，用于人体腔道狭窄处扩张手术。在扩张时需要使用球囊压力泵对球囊进行注液、加压并进行压力的监视，在抽负压时，需要非常方便的实现单人抽压并锁紧动作。目前临床上常规的一次性医用球囊压力泵基本都是螺纹推进式的，只是螺杆与螺母啮合、解锁的结构有所差别，典型的啮合、解锁结构有：偏心式、杠杆式、斜楔式等。由于设计结构的不同，所存在的问题也有不同,所有的结构均需通过人的手指来实现螺纹的啮合和解锁功能:偏心式结构需要第二个人伸手来帮忙才能顺利完成负压操作；杠杆式结构在负压下锁紧功能有失效的风险(即不能稳定形成负压状态)；斜楔式结构在抽负压时需要大拇指和食指同时作用做负压操作，虽然此结构能一气呵成地完成释放、抽气、锁紧的动作，但由于结构布置的原因，导致其容量相对较小，无法满足市场对大容量的需求。

如图2a,图2b及图4，活动块6包括第一锁紧边6a，中部开锁件6b和第二锁紧边6c，按压杠杆8的尾端，杠杆8的头端向外移动，带动活动块6的中部开锁件6b将第一锁紧螺母片2和第二锁紧螺母片4打开，使得杠杆8处于第二位置，松开杠杆8的尾端，在扭簧10作用下，第一锁紧边6a和第二锁紧边6b分别向内挤压第一锁紧螺母片2和第二锁紧螺母片4，杠杆8回到第一位置。
如图5和图6，第一锁紧螺母片2和第二锁紧螺母片4上分别设有与螺纹推杆适配的第一螺纹2a和第二螺纹4a，杠杆8处于第一位置时，如图7，使得第一锁紧螺母片、第二锁紧螺母片能够与螺纹推杆锁紧，杠杆8处于第二位置时，如图8，第一螺纹2a和第二螺纹4a的深度不影响螺纹推杆的径向移动。
本实施例在使用时，初始位置时，因为扭簧10的作用第一锁紧螺母片2及第二锁紧螺母片4处于锁紧状态、实现了活动卡钳的两钳臂对螺纹推杆1的限位，此状态旋转螺纹推杆1可以对已注液球囊进行加压，实现相应扩张手术。
如图2a、2b所示，若需进行快速注液、抽液或负压操作，则只需使用左手小指和无名指压住杠杆8即可克服扭簧10的扭力从而带动活动块6的中部开锁件6b，使第一锁紧螺母片2和第二锁紧螺母片4张开，第一螺纹2a和第二螺纹4a跟螺纹推杆1由啮合状态变为解锁状态，释放对螺纹推杆1的束缚；需要说明的是，在负压操作后需要松开释压的手指使得两锁紧螺母片2、4和螺纹杠杆1啮合从而到达保压的作用。
本实施例中，此处释放第一锁紧螺母片2和第二锁紧螺母片4的束缚进行注液、抽液或负压操作，最后保压整个动作一气呵成，操作简便。
本发明合理利用杠杆原理，以外管14上的中部销轴9作为支点，扭簧10定型，以活动块6的特定结构在杠杆的作用下能够使螺纹推杆1和两个锁紧螺母片2、4有效的啮合和脱开。
活动块6前端整体类似山字型结构，第一锁紧边6a，中部开锁件6b和第二锁紧边6c，能够有效的控制两个锁紧螺母片2、4与螺纹推杆1的啮合和脱离；活动块6的中部开锁件6b类似“Y”型内芯，因杠杆作用力向外移动带动“月牙形”左右两个锁紧螺母片2、4同时围绕销轴3转动达到与螺纹推杆1脱离的目的；释放杠杆8，在扭簧 10的作用下带动活动块6的第一锁紧边6a和第二锁紧边6c将“月牙形”左右锁紧螺母片同时围绕销轴3向内收拢转动，使左、右锁紧螺母片包住螺纹推杆1，并且保证左、右两个锁紧螺母片与螺纹杠杆有效锁紧。
第一锁紧螺母片2、第二锁紧螺母片4上的第一螺纹2a、第二螺纹4a及螺纹推杆1上特有的螺纹结构相适配。活动块“山字形”上第一锁紧边6a和第二锁紧边6c两内面有效包围第一锁紧螺母片2和第二锁紧螺母片4的外弧面是确保螺纹有效锁紧的关键，有此结构，压力泵在进行相应操作特别是保压操作时能够保证螺纹有效锁紧不失效。
实施例2：
如图9，第一锁紧螺母片2和第二锁紧螺母片4各通过一个销轴连接在固定座上。
本发明提供了一种医用充压控制装置，具体实现该技术方案的方法和途径很多，以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。本实施例中未明确的各组成部分均可用现有技术加以实现。
