Referring to fig. 1 to 3, an embodiment of the present invention provides a transfusion port positioning device, including a positioning seat 10, a positioning component 20 and a pressing component 30;

specifically, the positioning seat 10 is a C-shaped structure, and a gap 11 extending in the vertical direction is formed between two ends of the positioning seat;

the positioning component 20 comprises a positioning sticker 22, a mounting seat 21 and a positioning assembly 23; the positioning paste 22 is detachably arranged on the bottom surface of the mounting seat 21, the size of the positioning paste is matched with that of the gap 11, and the mounting seat 21 is detachably arranged between the gaps 11 and used for driving the positioning paste 22 to be pasted on skin; the positioning assembly 23 is arranged at the top of the mounting seat 21 and used for positioning an injection hole on an injection seat of the infusion port and guiding the butterfly wing needle to be vertically inserted into the injection hole;

the pressing member 30 is disposed on the positioning seat 10 and the positioning member 20, and is used for pressing and fixing the positioning seat 10 and the positioning member 20.

That is, when the mounting seat 21 of the positioning member 20 is mounted in the notch 11 of the positioning seat 10 of the C-shaped structure, the positioning seat 10 and the mounting seat 21 can form a closed structure, so that the transfusion port is limited and fixed, and the puncture error caused by the movement of the transfusion port during puncture is avoided. The positioning sticker 22 is arranged at the bottom of the mounting seat 21, so that when the sealing structure formed by the positioning seat 10 and the mounting seat 21 fixes the transfusion port, the positioning sticker 22 can be attached to the skin of the patient, and when the mounting seat 21 is detached from the notch 11, the positioning sticker 22 and the mounting seat 21 are detachably connected, so that the positioning sticker 22 can still be attached to the skin of the patient, and the positioning function of the positioning seat 10 is achieved.

When the device is used, firstly, the mounting base 21 is mounted in the notch 11 of the positioning base 10 to form a closed structure, then the closed structure formed by the mounting base 21 and the positioning base 10 is pressed and fixed on the skin by the pressing component to position and fix the infusion port, and at this time, the positioning patch 22 is adhered on the skin under the pressure of the mounting base 21. Furthermore, the medical staff finds the infusion hole on the injection seat, then carries out positioning through the adjusting component and keeps unchanged in the state, and after the positioning is finished, the positioning component 23 is used for guiding the punctured butterfly wing needle to vertically move downwards, and finally the butterfly wing needle is vertically inserted into the infusion hole. After the infusion is finished, the positioning sticker 22 is separated from the mounting seat 21, the mounting seat 21 is detached from the notch 11, and the notch 11 can be exposed, so that the butterfly needle can be taken out of the notch 11. Since the size of the positioning patch 22 is matched with the size of the notch 11, when puncturing is performed subsequently, only the notch 11 and the positioning patch 22 pasted on the skin of the patient need to be corresponded to each other, that is, the position of the positioning seat 10 is kept consistent with the position during the previous infusion, and since the position and the state of the positioning component 23 are not changed after the previous infusion, the position corresponding to the positioning component 23 is the position of the injection hole, so that the butterfly-wing needle can be directly guided to vertically puncture the injection hole. Thus, the positioning is more accurate, faster and more convenient, and the pressing piece 30 is arranged on the positioning seat 10 and the mounting seat 21, so that the finger pressing the pressing piece 30 is far away from the injection seat, thereby avoiding being punctured.
