The method comprises the following specific operations: the NS at the front end of the arterial catheter is firstly extracted by a 2ml syringe, then the NS and blood mixed liquid in the catheter is continuously extracted by a 5ml syringe, and finally relatively pure blood in the catheter is extracted by a proper syringe and then injected into a vacuum blood collection tube.
The problems that arise are:
1. the operation needs to connect the syringe for 3 times, and the action is complicated
2. Finally, the manipulation of injecting blood into the vacuum blood collection tube risks needle stick injuries
3. The amount of the finally collected blood is often quantified by experience, the result is inaccurate, more blood is drawn, and the residual blood can only be discarded; the pumping is less and needs to be performed again.
Therefore, it is imperative to develop a tool specifically for arterial catheter blood sampling.

Further, carry out the spiral and can dismantle the connection between the back pipe in the heparin tube and the baffle.
Further, the liquid cylinder and the mixing cylinder are of transparent plastic cylindrical structures, and scales with readable values are arranged on the surfaces of the liquid cylinder and the mixing cylinder.
The utility model has the technical effects that:
1. one part of the whole blood sampling process is in place, so that unnecessary complexity is avoided, and a blood sampler is protected; blood is not wasted, and the patient is intented to take; the times of connecting and disconnecting the injector and the arterial catheter blood sampling port are reduced, and the risk of infection is reduced.
2. Most patients in intensive care unit keep somewhere the artery pipe and be used for monitoring blood pressure, conveniently take a blood sample simultaneously, and daily blood sampling frequency is high, uses this artery pipe hemostix to all can improve work efficiency to a great extent.
3. The utility model has simple structure and scientific and reasonable design, and can effectively solve the problems of repeated injection and suction, easy puncture and inaccurate quantification in the existing blood sampling.
