Disposable locking type pressure precise filtering closed infusion set

Abstract

The invention discloses a disposable locking type pressure precise filtering closed infusion set belonging to the technical field of medical appliances. The invention adopts the technical scheme as follows: the disposable locking type pressure precise filtering closed infusion set consists of a disposable locking type precise filtering infusion set and an air-storing bag, wherein the disposable locking type 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, a locking type outer conical joint and a floating ball; and the air-storing bag comprises a bag body, a pipeline, a flow rate adjustor, a locking type inner conical joint, an inner conical joint protecting plug and an air precise filter. The disposable locking type pressure precise filtering closed infusion set can realize the locking type connection of the air-storing bag and the disposable locking type precise filtering infusion set and adopts high-pressure clean air in the air-storing bag 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 use lock-type 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 purpose of the present invention is to disclose a one-time use lock-ty...
