摘要：
A marking instrument for applying a fluid, said instrument comprising a main body having a replaceable cartridge receiving location and a cannula for puncturing a cartridge received at said location; a cartridge having a re-sealable diaphragm, said diaphragm allowing repeated puncture and sealing by said cannula, said cartridge further having a deformable wall portion; wherein said cartridge is biassed away from a puncturing position, movement into the puncturing position causing deformation of the deformable wall portion to thereby reduce the internal volume of the cartridge. In this regard, the reduction in the internal volume of the cartridge results in the pressure therein being increased, which will urge fluid contained in the cartridge to flow through the punctured resealable diaphragm.
摘要（中）：
一种用于施加流体的标记仪器，所述仪器包括具有可替换的盒接收位置的主体和用于刺穿在所述位置处接收的盒的套管; 具有可再密封隔膜的盒，所述隔膜允许所述插管反复穿刺和密封，所述盒还具有可变形壁部分; 其中所述筒体从穿刺位置偏压，进入穿刺位置，引起可变形壁部分的变形，从而减小药筒的内部容积。 在这方面，筒的内部体积的减小导致其中的压力增加，这将促使容纳在盒中的流体流过穿孔的可再密封隔膜。
