Problems solved by technology

[0002] The ordinary light-proof infusion sets used in clinical units of domestic medical institutions are mainly composed of bottle stopper puncturer protective cover, bottle stopper puncturer, air filter, infusion hose, dripping funnel cover, dripping funnel, liquid medicine filter, The flow regulator and the intravenous infusion needle are composed of a flow regulator and an intravenous infusion needle. During the clinical use of this product, in order to achieve the light-proof effect of the drug in clinical use, the manufacturer provides the liquid medicine channel such as: infusion hose, drip funnel, liquid medicine filter, infusion needle Connectors, hoses, etc. are directly processed by mixing light-shielding agent and raw materials (polyvinyl chloride pellets), so that during clinical use, the drug is directly in contact with the light-shielding agent, and the harmful substances in the light-shielding agent are easily released from The material is precipitated into the human body, and at the same time, the precipitated substance will chemically react with the drug components to produce harmful substances to the human body, which will lead to medical accidents due to unsafe medication and equipment.

Abstract

The invention discloses a disposable light-resistant infusion apparatus, which belongs to medical apparatus and instruments, and comprises a bottle stopper puncture device protective sleeve, an air filter and the like. A liquid medicine filter is formed by a filter outer shell, a liquid medicine filter membrane, a filter inner shell and an air filter membrane; the filter outer shell is of a dual-layer structure formed by colorless materials in an inner layer and black or brown materials in an outer layer through injection molding; and the filter inner shell is of a dual-layer structure formed by colorless materials in an inner layer and black or brown materials in an outer layer through injection molding. According to the invention, the liquid medicine filter inner shell and the filter outer shell are respectively formed by two materials with double colors through injection molding, the outer layer contains light-resistant agent while the inner layer does not contain light-resistant agent, the inner layer is directly contacted with liquid medicine, and the light-resistant agent materials in the outer layer is separated by the inner layer, so that the disposable light-resistant infusion apparatus is safe to use with medication, and medical negligence caused by instruments and medication is avoided. The disposable light-resistant infusion apparatus can be widely applied to venous transfusion with medicine needing to be light-resistant, and is also applied to general venous transfusion.

Description

technical field [0001] The invention belongs to medical equipment, in particular to a disposable light-proof infusion set. Background technique [0002] The ordinary light-proof infusion sets used in clinical units of domestic medical institutions are mainly composed of bottle stopper puncturer protective cover, bottle stopper puncturer, air filter, infusion hose, dripping funnel cover, dripping funnel, liquid medicine filter, Composed of a flow regulator and an intravenous infusion needle.
