Abstract

The invention discloses a heparin cap transparent rubber pad for indwelling needles. ~1.5 servings. The invention also discloses a production method of the heparin cap transparent rubber pad for indwelling needles, which solves the problem that the transparent rubber pad for indwelling needles currently used is not high in transparency, and the chemical cleanliness needs to be improved, especially the pH change value and ultraviolet absorbance of the product are easy For the problem of exceeding the standard, the vulcanization flash is controlled at 0.03‑‑0.10 mm, and the transparent rubber pad of the vulcanized heparin cap can be directly frozen to remove the edge. Vulcanized release of transparent rubber mats. The heparin cap transparent rubber pad for indwelling needles of the present invention can withstand multiple punctures, has excellent cleaning performance, has excellent compatibility with the sealing solution of the heparin cap, and has little extractables.

Description

technical field [0001] The invention relates to a rubber fitting for an indwelling needle for medical equipment, in particular to a transparent rubber pad for a heparin cap for an indwelling needle and a production method thereof. Background technique [0002] Traditional heparin cap transparent rubber pads for indwelling needles use traditional sulfur and zinc oxide accelerator systems of natural rubber or polyisoprene rubber. Sulfonamide and thiuram accelerators, in the production process, the use of these materials can easily cause the phenomenon of "sulphur spraying" on the transparent rubber pad of the heparin cap for the indwelling needle, and the UV absorbance, reducing substances and pH changes of the finished product It is easy to exceed the standard, so it is usually necessary to use a certain concentration of acid and alkali to perform high-pressure extraction treatment on the product. The production process is complicated and cumbersome, and it is easy to cause p...
