Method In the physical examination of the new students

we used the group method to compare disposable vacuum drawing and disposable needle drawing cliniclly. Results There is no significant different in the puncture succeeding rate（u=1.59

p>0.05）. But in the operative time

operant contaminative probability

person number of qualified blood volume

disposable vacuum drawing was better than disposable needle drawing（p<0.05）. Conclusion The vacuum drawing could shorten the operative time

increase test efficiency

diminish patients

suffering

refrain nurses from excessive contact with the blood sample

ensure safety of drawing and avoid cross contamination. This method was worthy of generalization.
