Abstract
Venipuncture is a commonly used clinical procedure. Venipuncture models are often used in training students in blood collection techniques, as the puncturing risks involved make it unfeasible for students to perform blood collection procedures on each other. Earlier studies have highlighted how such models cannot accurately represent human body characteristics, indicating that by training with these models, students can acquire only a limited number of techniques, compared to when training is conducted with human subjects. Therefore, models that closely approximate the human body need to be developed. In this study, we evaluated venipuncture models by using the discriminant analysis method to measure the vertical force and horizontal torque exerted when a needlepoint is applied to a model. To this end, puncturing experiments were performed using a current model with triaxial force sensors. The results showed that it was possible to differentiate between the characteristics of individual models, indicating that the characteristics of a model closely approximating the human body can be estimated objectively.
