Characterization and Development of Venipuncture Practice Rubber Model Based for BCG Economy Framework

Abstract

The Bio-Circular-Green (BCG) economy framework, which integrates economic, social, and environmental aspects for waste management, holds great promise for fostering growth across various sectors in Thailand. Venipuncture, a critical medical procedure, can lead to complications if not performed correctly. This study uses Thailand para latex resources and calcium carbonate extracted from recycled mollusk shells to develop an educational innovation model for venipuncture procedures. Natural rubber latex (NRL) was obtained from Chiang Rai, Thailand. Preserved latex was heated to obtain 60% concentrated latex, then combined with a sulfur solution, and calcium carbonate powder was added in various ratios. Molding used a specialized mold replicating anatomical features of the antecubital fossa, incorporating three prominent veins. The venipuncture practice rubber model was characterized for pH, moisture content, water absorption, tensile strength, and other properties. The model exhibited neutral pH, low moisture content, and notable resistance and elasticity. This study promotes the sustainable utilization of natural latex resources and recycled mollusk shells in developing innovative medical models within the BCG framework. Additional research is required to enhance the human friendliness and realism of the rubber material used in the venipuncture practice model.
