[0002] Most of the patients in hospital now use intravenous indwelling needles. When using them, the catheter and the needle core are punctured into the blood vessel together. When the catheter is completely in the blood vessel, the needle core is withdrawn, and only the soft catheter is left in the blood vessel for infusion treatment. On the one hand, it can reduce the pain of puncturing the blood vessels every day and protect the patients' blood vessels. On the other hand, it also reduces the risk of infection. Secondly, it is convenient for clinical medication, emergency medication for critically ill patients, and reduces the workload of nurses. Therefore, intravenous indwelling needles are widely used in clinical practice;

[0003] Traditional intravenous catheters do not have a dedicated fixing device. Generally, they are fixed at the location of the catheter using medical tape. The operation is complicated, and too much tape will be attached to the location where the catheter is fixed, affecting the heat dissipation of the skin at this location, which may cause certain adverse effects on it.

[0004] Therefore, in response to this situation, a venous indwelling needle fixing device has appeared on the market, such as a disposable venous indwelling needle fixing device patent with application number CN201811144829.3, which includes a fixing plate and a plurality of fixing belts, wherein the plurality of fixing belts are evenly arranged at both ends of the fixing plate, the fixing plate is provided with a plurality of air holes, the fixing plate and the fixing belt are both composed of a breathable plastic film, and medical adhesive is arranged on the inner side of the fixing plate and the inner side of the fixing belt; the fixing plate is a rectangular transparent plastic film, and the four corners of the fixing plate are provided with circular chamfers; the number of the fixing belts is four, two of which are arranged at the first short side end of the fixing plate, and two of which are arranged at the second short side end of the fixing plate, and the fixing belts located at the two short side ends are symmetrical along the horizontal axis of the fixing plate; although certain ventilation and heat dissipation problems have been solved, since the medical adhesive is arranged on the inner side of the fixing plate, the heat dissipation is good enough, but it will still have a certain impact on the skin, such as causing rashes on the skin when it is hot;

[0005] Therefore, in view of the technical problems described above, there is an urgent need for a venous indwelling needle fixing device. Utility Model Content
