The invention relates to a drop tube press stop device.The main reason is that the body is fixedly provided with a lower clamping seat and a movable upper clamping seat.The burette shall be clamped on the lower clamp seat and the upper clamp seat.An elastic element is connected between the lower clamping seat and the upper clamping seat.When the upper clamping seat is pushed upward by a push rod,The locking convex part of the upper clamping seat can be positioned with the locking part.A push rod is arranged on the embedded part.One end of the push rod is provided with a push part for pushing the plug convex part out of the plug part.At the other end of the push rod, a control end is formed, which is controlled by the control part to drive the push part to operate.In addition, the upper sensing element and the lower sensing element are respectively provided in the body.The upper sensing element and the lower sensing element sense the flow state of the medical liquid in the drip tube；In this way,At the end of the flow and dripping of the medical liquid in the pipette,The drip pipe can be controlled to be squeezed and pressed by the lower clamping seat and the upper clamping seat.So that the liquid can no longer pass through,In contrast, the patient's blood will not flow back.To prevent the occurrence of conditions that affect the health of patients.The utility model is more practical in its overall implementation and use.本創作係有關於一種點滴管壓止裝置，其主要係於本體內固設有下卡合座及活動設有上卡合座，令點滴管繞設卡合於該下卡合座及該上卡合座，該下卡合座與該上卡合座間連結有彈性元件，於利用推桿推動該上卡合座向上移動時，該上卡合座之嵌掣凸部能與嵌掣部嵌掣定位，對應該嵌掣部設有頂推桿，該頂推桿一端形成有頂推部供將該嵌掣凸部由該嵌掣部內向外推出，於該頂推桿另一端則形成控制端受控制件控制帶動該頂推部作動，又於本體內分別設有上感應元件及下感應元件，該上感應元件及該下感應元件供感應該點滴管內之醫療液體的流動狀態；藉此，於點滴管內之醫療液體流動滴落完畢時，能控制令該點滴管受到下卡合座及上卡合座予以擠壓壓掣，以讓液體無法再行通過，相對即讓病患血液不會有回流狀態，防止有影響病患身體健康之情況發生，而在其整體施行使用上更增實用功效特性者。
