Disposable pressure precise filtering closed infusion set

Abstract

The invention discloses a disposable pressure precise filtering closed infusion set belonging to the technical field of medical appliances. The invention adopts the technical scheme as follows: the disposable precise-pressure filtering closed infusion set consists of a disposable precise filtering infusion set and an air-storing bag, wherein the disposable precise filtering infusion set comprises a bottle plug puncture unit projecting jacket, a bottle plug puncture unit, a burette, an injection piece, a dropping funnel, a liquid medicine precise filter, a pipeline, a flow rate adjustor, an outer conical joint, an outer conical joint protecting jacket and a floating ball; and the air-storing bag comprises a bag body, a pipeline, a flow rate adjustor, an inner conical joint, an inner conical joint protecting plug and an air precise filter. The disposable pressure precise filtering closed infusion set technically ensures that high-pressure clean air is used as the power for infusing the liquid medicine, in addition, the liquid medicine is precisely filtered, and fully closed infusion can be performed quickly with controllable flow rate of the liquid medicine. The invention can avoid air pollution in the infusion process, can prevent bacteria, virus and dust from entering the human body, prevent infusion reaction and phlebitis from occurring and prevent air embolism from generating caused by negligence of personnel to endanger the life.

Description

Technical field: [0001] The invention discloses a one-time pressure precision filter sealing infusion set, which belongs to the technical field of medical equipment. Background technique: [0002] The air filter on the existing disposable infusion set (gravity infusion type) can only ensure that more than 90% of particles above 0.5 μm in the air can be effectively removed, and it can only filter out dust in the air, and it is difficult to remove living microorganisms ( bacteria, viruses and pyrogens). The liquid medicine filter can only ensure that more than 80% of the particles above 20 μm in the liquid medicine can be effectively removed. Such bacteria, viruses, and dust particles pollute the original sterile, pyrogen-free, particle-free medicines and the entire infusion system, and people will have infusion reactions, which will aggravate the condition. Invention content: [0003] The object of the present invention is to disclose a one-time pressure precision filter ...
