在病理生理教学和科研实验中,常需采用小动物的血液。动脉,静脉或心腔穿刺以及眼眶取血虽然可用,但很难达到及时、反复采血的目的。我们用血管插管,连接三通活塞,再以玻璃毛细管插入三通活塞侧孔采血,深觉此法切实可行。适用于家兔和大白鼠,每次可采血140至160微升,并可反复及时、准确采血样。尤其适用于对血样要求严格的实验,如血气分析(隔离空气),也可动、静脉同时采血,此法成功率可达100%,方法简介如下: (1) 选择适当的采血血管,切开皮肤,分
In the pathophysiology teaching and research experiments, often need to use the blood of small animals. Although arterial, venous or cardiac puncture and orbital bleeding are available, it is difficult to achieve the goal of timely and repeated blood sampling. We use vascular cannulation, connecting three-way piston, and then inserted into the glass capillary three-way piston side hole blood, deep feel this method is feasible. Suitable for rabbits and rats, each can take blood 140 to 160 microliters, and can be repeated promptly and accurately blood samples. Especially suitable for demanding experiments on blood samples, such as blood gas analysis (isolated air), but also mobile, venous blood at the same time, the success rate of this method up to 100%, the method is as follows: (1) Select the appropriate blood vessels, incision Skin, points
