[0027] Specifically, the anti-stabbing blood extractor with a flushing device provided by the utility model comprises a pressure connecting pipe 1, a three-way valve 2, a flushing assembly 3 and a blood extractor 4. When the device is used to extract blood from a patient, the pressure connecting pipe 1 is connected with an arterial pressure detector on the patient's hand, so that the blood enters the three-way valve 2 through the pressure connecting pipe 1, the connection relationship between the passages of the three-way valve 2 is adjusted, the first passage 21 is communicated with the third passage 23, and the blood in the three-way valve 2 enters the blood extractor 4. After the blood extraction is completed, blood residues exist in the three-way valve 2, the connection relationship between the passages of the three-way valve 2 is changed again, the first passage 21 is communicated with the second passage 22 and the third passage 23, the blood extractor 4 is extracted, the third passage 23 is emptied, and then the flusher 32 is pushed, so that the liquid in the flusher 32 is injected into the three-way valve 2 for flushing. The device can effectively prevent needle stick injuries and occupational exposure, and also saves blood extraction time.

[0028] In some possible implementation manners, the other end of the pressure connecting pipe 1 is connected with an arterial pressure detector, the center lines of the first passage 21 and the third passage 23 are parallel to each other, and the center lines of the second passage 22 and the first passage 21 are perpendicular to each other.

[0029] Specifically, when blood sampling is needed, the arterial pressure detector is opened, so that blood flows into the power pressure pipe due to the action of arterial pressure.

[0030] In some possible implementation manners, the flusher 32 comprises a connector 321 and a pipe body 322, the other end of the flush connecting pipe 31 is connected with one end of the connector 321, and the other end of the connector 321 is connected with the pipe body 322.

[0031] Specifically, after blood sampling is completed by using the device, the blood extractor 4 is pulled out, the first passage 21 is emptied, and then the flusher 32 is pushed, so that the liquid in the pipe body 322 is input into the three-way valve 2 through the connector 321, the passages of the three-way valve 2 are flushed, and then the liquid is discharged through the first passage 21.
