[0025] Reference Figure 1 As shown, the utility model provides a technical solution: an auxiliary puncture device includes a puncture needle body 1, an auxiliary component 3 is provided on the arc surface of the puncture needle body 1, and a collecting component 2 is provided at the lower end of the puncture needle body 1.
[0026] The following describes in detail the specific settings and functions of the collection component 2 and the auxiliary component 3.
[0027] Reference Figure 2 and Figure 3 As shown, in this embodiment: the collecting assembly 2 includes an outflow tube 21 fixedly connected to the lower end of the puncture needle body 1, and the arc surface of the outflow tube 21 is provided with a rubber tube 22. The lower end of the rubber tube 22 is fixedly connected to the collecting bag 23. By setting the collecting assembly 2, when it is necessary to collect blood flowing out of the puncture needle inserted into the vein, the rubber tube 22 is inserted into the outflow tube 21, and then the puncture needle is inserted into the vein. When the blood flows to the end of the puncture needle, the blood flows to the outflow tube 21, then passes through the rubber tube 22, and finally flows out into the collecting bag 23 , thereby avoiding the effect of contamination caused by blood flowing out of the vein when the puncture needle is inserted as much as possible, the inner wall of the puncture needle body 1 is provided with an outflow groove 24, by setting the outflow groove 24, the blood flowing out of the puncture needle body 1 is reduced, and the right end of the puncture needle body 1 is fixedly connected with an anti-outflow ring 25, by setting the anti-outflow ring 25, the blood outflow of the puncture needle body 1 is helped to be reduced, and the collection bag 23 is filled with negative pressure air. The negative pressure air in the collection bag 23 helps to suck the blood flowing out of the puncture needle into the collection bag 23.
[0028] Reference Figure 2 As shown, in this embodiment: the auxiliary component 3 includes a stretching block 31 arranged on the arc surface of the puncture needle body 1. When using the puncture needle for puncture, the puncture needle body 1 is pushed to the patient's vein, so that the stretching block 31 contacts and stretches the patient's venous wound, thereby assisting the puncture needle puncture. The arc surface of the puncture needle body 1 is provided with a thread groove 32, and the thread groove 32 is threadedly connected to the stretching block 31. By setting the thread groove 32, the stretching block 31 is screwed and threadedly connected to the puncture needle body 1. The stretching block 31 is set to a cone. By setting the stretching block 31 to a cone, the patient's venous wound is contacted and stretched.
[0029] Working principle:
[0030] When performing a venipuncture operation on a patient, the puncture needle body 1 is inserted into the patient's vein, and then the blood in the vein flows out from the other end of the puncture needle body 1. Then, the end of the puncture needle body 1 where the blood flows out is inserted into the guide wire into the vein, and then the puncture needle body 1 is pulled out, and the wound where the puncture needle body 1 is inserted into the vein is enlarged using a flaring pliers, and then the venous sheath is placed into the blood vessel along the guide wire, and finally the guide wire is taken out, and the blood return is confirmed to be good. When it is necessary to collect the blood flowing out of the vein where the puncture needle is inserted, the rubber tube 22 is inserted into the outflow tube 21, and then the collecting puncture needle is inserted into the vein. When the blood flows to the end of the puncture needle, the blood flows to the outflow tube 21, then passes through the rubber tube 22, and finally flows out into the collection bag 23, thereby avoiding as much as possible The blood flowing out of the vein when the puncture needle is inserted causes contamination, so the blood flowing out is assisted in collecting the blood. By setting the outflow groove 24, the blood flowing out of the puncture needle flows into the outflow groove 24, reducing the blood flowing out of the puncture needle body 1. By setting the anti-outflow ring 25, the blood flowing out of the puncture needle body 1 is assisted in reducing. There is negative pressure air in the collection bag 23, which assists in sucking the blood flowing out of the puncture needle into the collection bag 23. When using the puncture needle for puncture, the puncture needle body 1 is pushed to the patient's vein, so that the expansion block 31 contacts and expands the patient's venous wound, thereby assisting the puncture needle puncture. By setting the threaded groove 32, the expansion block 31 is twisted to be threadedly connected to the puncture needle body 1. The expansion block 31 is set to a cone shape to contact and expand the patient's venous wound.
