This study aimed to develop and evaluate the effectiveness of an innovative natural rubber infant manikin for suction skill practice. The research was conducted in two phases. Phase 1 involved the design and development of the innovative natural rubber infant manikin for suction skill practice. Phase 2 focused on evaluating the effectiveness of the developed manikin. The sample consisted of 27 third-year Bachelor of Nursing Science students at Boromarajonani College of Nursing, Songkhla, in the 2024 academic year. The research instruments included: (1) a natural rubber infant manikin for suction skill practice, and (2) a questionnaire assessing the effectiveness of the innovative natural rubber infant manikin. The effectiveness questionnaire demonstrated an item–objective congruence (IOC) index of 0.78 and a Cronbach’s alpha reliability coefficient of 0.77. Data were analyzed using content analysis, descriptive statistics including means, standard deviations, frequencies, and percentages. The research findings revealed that:
1. Innovative natural rubber infant manikin for suction skill practice: (1) External characteristics: The innovation was developed using natural rubber latex. The infant manikin is designed with an oral cavity and nasal openings. (2) Internal characteristics: The oral cavity is connected to the trachea, which extends to a simulated lung hilum model. The lung hilum model is designed as a container with an openable lid and a connector to the trachea. Inside the lung hilum model, a liquid substance simulating sputum is contained.
2. Effectiveness of the innovative natural rubber infant manikin: Overall effectiveness was rated at the highest level (M = 4.53, S.D. = 0.63). The structural dimension demonstrated a high level of effectiveness (M = 4.45, S.D. = 0.68), while the usability dimension demonstrated the highest level of effectiveness (M = 4.60, S.D. = 0.57), respectively.
The findings indicate that this innovation can be effectively implemented in teaching and learning activities in pediatric and adolescent nursing courses, both in laboratory and clinical practice components. The manikin’s anatomically and physiologically realistic design enhances students’ understanding and builds confidence in practicing infant suctioning skills. Future studies should further refine the development of the natural rubber infant suction training manikin to enhance its effectiveness. Comparative studies between conventional manikins and the natural rubber infant manikin are recommended, as well as studies involving larger sample sizes.
