带旋转夹紧阀的医疗注射系统
摘要：
在此披露了一种医疗注射系统(100)，包括一种阀装置(23)，该阀装置包括一个夹紧构件(233)和两个弹簧加载的砧座(271,272)。该注射系统的两个管线(27-F,27-I)被定位在该夹紧构件与该砧座之间，这样使得当该夹紧构件通过该构件所联接的一个轴(232)的旋转而移动到与砧座相邻的一个夹紧位置中时，该夹紧构件抵靠该弹簧加载的砧座挤压该相应的管线。该夹紧构件是围绕一个辅助轴线可旋转的，该辅助轴线与该轴的一个中心轴线偏心或从其偏移。每个弹簧加载的砧座的一个弹簧构件是预加载的。在某些应用中，该夹紧构件在移动到该夹紧位置中时施加一个大于约45磅的夹紧力，例如以便阻止在高达约1200psi的一个注射压力下穿过该管线的流动。
摘要（英）：

A medical injection system (100) including a valve apparatus (23) including a pinching member (233) and two spring-loaded anvils (271, 272). Two tubing lines (27-F, 27-1) of the injection system are positioned between the pinching member and the anvils, such that when the pinching member is moved into a pinching position adjacent to an anvil by rotation of a shaft (232) to which the member is coupled, the pinching member compresses the corresponding tubing line against the spring-loaded anvil. The pinching member is rotatable about an auxiliary axis, which is eccentric, or offset from a central axis of the shaft. A spring member of each spring-loaded anvil is pre-loaded. In certain applications, the pinching member, when moved into the pinching position, applies a pinching force of greater than approximately 45 pounds, for example, to prevent flow through the tubing line at an injection pressure of up to approximately 1200 psi.
