设计一种新的大鼠静脉输液装置

Development of a new intravenous transfusion device for rats

目的:研制一种简易可靠的大鼠静脉输液装置。方法:利用注射器、肝素帽、硬膜外导管等材料,设计制作大鼠静脉输液装置,用于30只全小肠切除大鼠,观察大鼠在自由活动情况下静脉输液的效果,以验证该装置的有效性。结果:该装置能维持全小肠切除大鼠实验期间的静脉输液14 d,无脱管、渗漏和堵塞等意外。结论:该装置能较长时间维持大鼠静脉输液的需要,材料易得,制作简易。

Objective： To design a simple and reliable swivel device for rat intravenous transfusion. Methods： ClinicaI staples such as heparin cap and syringe were used to design a swivel intravenous transfusion device which was applied in 30 rats with total small bowel resection. The effect of maintaining long-term intravenous transfusion and free movement in rats was observed for the reliability and practicability of this device. Results： During the whole test, 27 total small bowel resection rats went through the intravenous transfusion successfully by the device and endured the maximum time of 21 d without fall-off intertwist and wall-up. Conclusion： The newly-designed swivel intravenous transfusion device ,with easily obtaining materials and simple making,can meet the need of rat vein transfusion for 2 weeks.
