In the present study, we developed a sphygmomanometer for nursing students and evaluated how it affected their technique acquisition related to blood pressure measurement as a teaching material. The subjects in this study comprised a total of 138 nursing students at the nursing department of University A. The first group was the “improved sphygmomanometer group” and consisted of 58 students who entered the program in 2015 and practiced using the improved sphygmomanometer. The control group was the “normal sphygmomanometer group” and consisted of 61 students who entered the program in the previous year (2013) and practiced using the normal sphygmomanometer. Instructors assessed the effects, which were grouped under the three categories of “cuff placement (three items) ”, “cuff deflation”, and “listening to the sounds”. No differences were found between the two groups in terms of “cuff placement” and “listening to the sounds”. However, the improved sphygmomanometer group performed “cuff deflation” more accurately than the normal sphygmomanometer group (P＜0. 01). The improved sphygmomanometer allowed visualization of the deflation rate, making it possible for students to evaluate their own deflation rates more objectively, which, therefore, appeared to lead to accurate technique acquisition. In the future, we will explore new methods for students to practice “cuff placement” and “listening to the sounds” more effectively. 　本研究は, 看護学生が血圧測定技術を習得するための教材として, 血圧計の開発を行い, その効果を検討した. 研究対象は, A大学看護学科にH25年度入学の通常血圧計を使用して練習した1年生61名 (以下, 通常血圧計使用群), H27年度入学の教材用血圧計を使用して練習した58名 (以下, 教材用血圧計使用群) である. 効果は, 「マンシェットの巻き方 (3項目) 」, 「減圧速度」, 「コロトコフ音の聴き取り」について, 教員による他者評価で行った. 「マンシェットの巻き方」と「コロトコフ音の聴き取り」には差がなかったが, 「減圧速度」は教材用血圧計使用群が, 通常血圧計使用群より正しくできていた (P＜0. 01). 教材用血圧計では減圧速度が可視化されるため, 自己の減圧速度を客観的に評価でき, 正確な技術習得につながったと考えられる. 今後は, 「マンシェットの巻き方」や「コロトコフ音の聴き取り」にも効果的な練習ができるよう教材の検討をしていく.
