用于由于针头脱出自动终止流动的系统和方法
摘要：
一种用于流体输送的自动流动终止的系统和方法，其包括：壳体，其被构造成将流体输送管联接至构造成在患者的组织内皮下输送流体的针头；以及弹簧加载激活机构，其具有对应于基本上邻近于组织设置壳体和针头存放在组织内的情况的第一方向以及对应于壳体远离组织设置或针头从组织脱出的情况的第二方向。流终止机构联接至激活机构，当激活机构处于第一方向时，流终止机构具有允许从流体输送管至针头的流的打开配置；当激活机构处于第二方向时，流终止机构具有基本上终止从流体输送管至针头的流的关闭配置。
摘要（英）：

Systems and methods for automatic flow termination for fluid delivery, including a housing configured for coupling a fluid delivery tube to a needle configured for subcutaneous delivery of fluid within a tissue of a patient and a spring-loaded activation mechanism having a first orientation corresponding to a condition where the housing is disposed substantially adjacent to the tissue and the needle lodged within the tissue and a second orientation corresponding to a condition where the housing is disposed away from the tissue or the needle being dislodged from the tissue. A flow termination mechanism is coupled to the activation mechanism and having an open configuration allowing flow from the fluid delivery tube to the needle when the activation mechanism is in the first orientation and a closed configuration substantially terminating flow from the fluid delivery tube to the needle when the activation mechanism is in the second orientation.
