Abstract

The invention discloses a rubber plug for a puncture-type infusion connecting member heparin cap and belongs to the technical field of medical instruments. The rubber plug comprises, by weight, 100 parts of isoprene rubber, 3-5 parts of transparent zinc oxide, 1-3 parts of stearic acid, 1-1.3 parts of sulfur, 0.1-0.4 part of promoter TRA, 0.1-0.3 part of promoter TMTM and 5-8 parts of lightweight magnesium carbonate. The rubber plug has the advantages of stable physiochemical and biological performance, excellent compatibility with medicine, resistance to perforation, good closing performance after puncture and capability of meeting clinical using needs.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a rubber stopper for a medical device, in particular to a rubber stopper for a heparin cap of a puncture-type transfusion connector. The rubber plug for the heparin cap of the puncture-type transfusion connector of the present invention has stable physical, chemical and biological properties, excellent compatibility with drugs, perforation resistance, good closure performance after puncture, and meets clinical use requirements. Background technique [0002] Isoprene rubber is the abbreviation of polyisoprene rubber, which is produced by solution polymerization. Like natural rubber, isoprene rubber has good elasticity and wear resistance, excellent heat resistance and good chemical stability. The strength of raw isoprene rubber (before processing) is significantly lower than that of natural rubber, but its quality uniformity and processing performance are superior to natura...
