The invention discloses a safety infusion set, which comprises a safety mechanism which is arranged on an infusion pipeline, wherein the safety mechanism comprises a shell and a floating body which is positioned in the shell; the shell comprises a liquid outlet part; the liquid outlet part is arranged at the bottom of the shell; the floating body comprises a base body and a convex block; the convex block is arranged on the base body; when the liquid surface in the shell is lower than a liquid outlet above the liquid outlet part, the convex block is embedded into a liquid passage in the liquid outlet part due to gravity and is in contact with the liquid passage in the liquid outlet part, and the convex block deforms due to extrusion under the gravity action, so that the convex block is closely attached to the liquid passage in the liquid outlet passage and is blocked by the liquid outlet part. The safety infusion set has a simple structure, is safe and pollution-free and has high sealing property.
Description
technical field [0001] The invention relates to an infusion set, in particular to a safety infusion set. Background technique [0002] When carrying out intravenous infusion to patient at present, safety infusion set is widely used, prevents cross-infection between patients like this and has played a positive role. Disclosed notification number in China is a kind of disposable safety transfusion device of CN100534543C, comprises the needle for inserting bottle, dropping funnel, flexible pipe, liquid medicine filter and intravenous infusion needle that are arranged in sequence.
