Abstract

The invention discloses an anti-coagulation liquid stop infusion apparatus with a piece of flow control liquid drug filter film. The anti-coagulation liquid stop infusion apparatus comprises a bottle stopper puncture device, an upper infusion pipe, a dropper, a dropping bucket, a lower infusion pipe, a flow rate regulator, an external conical joint, a capillary infusion pipe, a side wing and an intravenous injection needle and is characterized in that an exhaust pipe is inserted in the lower neck part of the dropping bucket, a liquid lead hole with a drainage tube is formed in a lower bottom support of the dropping bucket, and the other end of the drainage tube is connected with the downside of the dropping bucket through an upper seal cover of a liquid stop liquid drug filter connected with the lower infusion pipe; the flow control liquid drug filter film for realizing a micro-flow rate when infusing is welded in the zone between the position near the liquid lead hole and a second convex pipe. The anti-coagulation liquid stop infusion apparatus with the flow control liquid drug filter film is capable of avoiding sludged blood due to infusion cutoff of the intravenous injection needle after the infusion apparatus stops infusing liquid for a long time.

Description

【Technical field】 [0001] The invention relates to a one-time use infusion set, and is especially suitable for a one-time use anticoagulant hemostatic liquid infusion set. 【Background technique】 [0002] At present, some liquid stopper infusion devices, after stop liquid start, just do not have transfusion to be transfused into the vein under the intravenous injection needle again. In general patients, after a period of hemostasis, if there is no nurse to deal with it, there will be blood clots at the intravenous injection needle; in addition, almost all severe patients with diseases will cause blood coagulation disorders, if this This kind of patient uses stop liquid infusion set, after stop liquid, in a short time, blood coagulation will take place in intravenous injection needle. Once a blood clot occurs, it will panic the patient and even cause disputes between doctors and patients. 【Content of invention】 [0003] In order to overcome the above-mentioned shortcomings ...
