The subclavian venous puncture catheter has been widely used in treatment of critically ill patients. However, the lack of a mechanical model for subclavian vein puncture and selection of puncture parameters lead to procedure failures. This paper develops a puncture force model, and explores the factors affecting puncture force through a series of experiments. The puncture process is divided into four stages, and a mechanical model is established for each stage. The parameters of the puncture model, including the needle insertion angle and diameter, and venous pressure, are analyzed experimentally using biological tissues. The Box–Behnken experiment design is chosen to account for the cross-interactions of the various factors considered.
