[0024] When it is necessary to puncture the patient's arm artery, the two needle wing plates 503 are pressed close to each other, and the needle wing plate 503 is held in the hand (the deformation plate 502 connected to the needle wing plate 503 is a deformable PVC material, and the deformation plate 502 begins to deform at this time). By moving the needle wing plate 503, the puncture needle 1 can be driven to pierce the patient's artery from the designated position to achieve the purpose of puncture. When the patient's hemodialysis is completed, the anti-skid pad 203 is held in the hand and the anti-skid pad 203 is moved at this time because the anti-skid pad 203 is The fixing plates 202 are connected to each other, and the fixing plates 202 are installed on the receiving tube 201. At this time, the receiving tube 201 starts to drive the puncture needle 1 to move away from the patient, so that the puncture needle 1 can be removed from the patient's arm. It can be directly removed from the fixing plates 202 and the anti-slip pad 203, and there is no need to hold the needle wing plate 503 (in the process of pressing the needle wing plate 503 to remove the needle, the needle may be offset, thereby increasing the patient's pain), which is more convenient and quick, and reduces the patient's pain;

[0025] The auxiliary component 5 is interconnected with the needle pipe 4; the auxiliary component 5 includes a connecting sleeve 501 and a deformation plate 502, and the connecting sleeve 501 is arranged on the outer surface of the connecting tube 3, and the deformation plate 502 is arranged at the lower end of the outer surface of the connecting sleeve 501; the auxiliary component 5 also includes a needle wing plate 503, a hand-sticking plate 504 and an anti-slip protrusion 505, and the needle wing plate 503 and the deformation plate 502 are interconnected, and the hand-sticking plate 504 is arranged at the lower end of the needle wing plate 503, and the anti-slip protrusion 505 is arranged at the lower end of the hand-sticking plate 504; the auxiliary component 5 also includes a fixing tape 506, a release film 507 and a tear paper 508, and the fixing tape 506 is arranged at the side of the upper surface of the needle wing plate 503, and the release film 507 and the adhesive surface of the upper surface of the fixing tape 506 are mutually attached, and the tear paper 508 and the release film 507 are mutually connected;

[0026] After the puncture needle 1 is inserted into the designated position on the patient's arm, the pressed needle wing plate 503 is released. At this time, under the action of the deformation plate 502 restoring the deformation, the needle wing plate 503 returns to the horizontal position. At this time, the hand-sticking plate 504 installed at the lower end of the needle wing plate 503 begins to move in the direction close to the patient's arm, until the anti-slip protrusion 505 installed at the lower end of the hand-sticking plate 504 fits against the patient's arm. At this time, the lower end of the connecting tube 3 is no longer in contact with the patient's arm, thereby avoiding excessive squeezing of the patient's arm by increasing the contact area, and then pulling the tear paper 508. At this time, the fixing tape 506 and the release film 507 are pulled together (the lower end of the fixing tape 506 is set to a smooth surface, and the upper end is set to a When the fixing tape 506 and the release film 507 are rotated 180°, the tear-off paper 508 is torn off. Because the tear-off paper 508 is installed on the release film 507, the release film 507 begins to be torn, that is, the release film 507 begins to move away from the fixing tape 506. It can be seen that the release film 507 is removed from the fixing tape 506. After that, the fixing tape 506 can be pasted on the patient's arm to achieve the purpose of auxiliary fixation of the puncture needle. Medical staff no longer need to press and take the tape, which is more convenient and quick.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
