In clinical practice, radiopharmaceutical dynamic imaging technology requires the bolus injection method to complete injection. Due to the failure rate and radiation damage of manual injection, even experienced technicians still bear a lot of psychological burden. This study combined the advantages and disadvantages of various manual injection modes to develop the radiopharmaceutical bolus injector, and explored the application of automatic injection in the field of bolus injection from four aspects: radiation protection, occlusion response, sterility of injection process and effect of bolus injection. Compared with the current mainstream manual injection method, the bolus manufactured by the radiopharmaceutical bolus injector based on the automatic hemostasis method had a narrower full width at half maximum and better repeatability. At the same time, radiopharmaceutical bolus injector had reduced the radiation dose of the technician's palm by 98.8%, and ensured more efficient vein occlusion recognition performance and sterility of the entire injection process. The radiopharmaceutical bolus injector based on automatic hemostasis has application potential in improving the effect and repeatability of bolus injection.
在临床实践中，放射性药物动态成像技术需要采用团注法完成注射。由于手动注射存在失败率和辐射损伤问题，即便经验丰富的技术人员仍承受着较大的心理负担。本研究综合了各种手动注射方式的优缺点，研发了放射性药物团注注射器，并从辐射防护、堵塞反应、注射过程的无菌性以及团注效果四个方面探讨了自动注射在团注领域的应用。与当前主流的手动注射方法相比，基于自动止血法的放射性药物团注注射器所制造的团注半高宽更窄，重复性更好。同时，放射性药物团注注射器使技术人员手掌的辐射剂量降低了98.8%，并确保了更高效的静脉堵塞识别性能以及整个注射过程的无菌性。基于自动止血的放射性药物团注注射器在提高团注效果和重复性方面具有应用潜力。
