Further, the external diameter of described plugging pin equals the internal diameter of draw point.
Further, the diameter of the pore described draw point arranged is 1.5 ~ 2.0mm.
Further, the pore on described draw point and the distance between described draw point needle stand are 2 ~ 3mm.
Further, the length of described plugging pin is 12 ~ 14mm.
Further, the distance between described outage and sealing rubber plug is 1 ~ 1.5mm.
Further, the thickness of described sealing rubber plug is 0.5 ~ 0.8mm.
Beneficial effect of the present invention:
1) arterypuncture needle construction of the present invention is simple, for there being the monitoring of wound arterial pressure, improving puncture success rate, shortening the puncture time.
2) arterial puncture needle of the present invention is convenient to take a blood sample in testing process carry out blood gas analysis, does not have blood and ooze out in blood collection procedure, pollutes blood sampling point.
