A device for holding an IV tube in a pumping apparatus and for selectively occluding the tube when the door of the pumping apparatus is opened, to prevent free flow of fluid in the tube. A flange provided on a sliding clamp is designed to prevent inadvertent finger slippage causing pushing of a tab positioned in the sliding direction from the flange, resulting in undesirable fluid leakage. The flange is made slip-resistant using a textured surface, having a concave shape, or having an angled top portion to prevent finger slippage or having a concave setback to guide a finger when pushing the sliding clamp.本發明係有關一用於固持一靜脈注射(IV)管於一泵送裝備中且用於當泵送裝備的門開啟時選擇性阻塞該管以防止管中流體的自由流動之裝置。一設置於一滑動夾件上之凸緣係被設計成防止意外手指滑移造成一位於滑動方向中之籤片自凸緣的推押,而導致不良的流體洩漏。凸緣係利用一紋路狀表面製成抗滑移性,具有一凹形形狀,或具有一傾斜頂部分以防止手指滑移或具有一凹形退縮部以當推押滑動夾件時引導一手指。12...箱形基底14...滑動夾件15...滑動夾件14的體部16...塔件17...體部15的頂表面18...公管連接器19...體部15的底表面20...長形開孔21...塔件16的頂端22...軌23...塔件16的底端24...框架25...基底12的頂表面26...遠自由端27...軌通路28...撓性懸臂式鎖定臂30...鎖定突部32...釋放籤片40...拉取突部101...凸緣103...滑動夾件14的遠端105...近端111...滑動方向,箭頭
