[0002] The intravenous indwelling needle is also called intravenous cannula needle. The core components include soft catheter / cannula that can be left in the blood vessel and stainless steel puncture guide needle core. When using, the catheter and needle core are punctured into the blood vessel together, and when the catheter enters the blood vessel completely, the needle core is withdrawn, and only the soft catheter is left in the blood vessel to perform infusion treatment. In the conventional use, it is used with sanitary cotton and adhesive tape.

[0003] The medical indwelling needle plays an indispensable role in medical practice, but some details need to be optimized during its use. The tail joint of the indwelling needle is often fixed on the surrounding skin to facilitate subsequent injection, especially when injecting medicine through the tail joint of the indwelling needle each time, the adhesive tape needs to be repeatedly torn off and pasted, the repeated tearing of the adhesive tape increases the workload of medical staff, the significant increase in the use cost of the adhesive tape also leads to the increase in the burden of the patient's skin pasting place. This frequent operation not only affects the medical efficiency, but also causes unnecessary waste of medical resources.

[0004] More importantly, due to the large size of the tail joint of the indwelling needle, the indwelling needle may cause local pressure injury to the human skin during long-term use. This pressure injury not only brings additional pain to the patient, but also may affect the use effect of the indwelling needle, and even increase the risk of infection. UTILITY MODEL CONTENTS

[0005] The utility model aims to solve the problem of repeated tearing of adhesive tape when refixing the existing indwelling needle, which leads to the pain of the patient caused by repeated pasting and tearing of the adhesive tape and the increase in the cost of the adhesive tape caused by repeated tearing, and provides an indwelling needle fixing device.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the technical scheme that:

The arrangement of the waterproof layer can effectively prevent external moisture from entering the inside of the sticking part, avoid the erosion of the moisture to the indwelling needle and the skin around the indwelling needle, and reduce the risk of infection. By preventing the invasion of moisture and bacteria, the sticking part designed in this way helps to keep the indwelling needle and the skin around the indwelling needle clean and dry, thereby reducing the risk of infection.

[0016] As a preferred scheme of the utility model, a bacteriostatic layer is arranged between the sticking layer and the waterproof layer, and the bacteriostatic layer is connected with the sticking layer and the waterproof layer respectively.

[0017] In the scheme, a bacteriostatic layer is arranged between the sticking layer and the waterproof layer, and the bacteriostatic layer is connected with the sticking layer and the waterproof layer respectively. The existence of the bacteriostatic layer can effectively inhibit the growth of bacteria in the sticking part and the surrounding environment. This is crucial for preventing indwelling needle-related infections and can significantly reduce the incidence of infection and protect the health of patients. Since the bacteriostatic layer can inhibit bacterial growth and protect skin health, the sticking part can remain relatively clean and clean, thereby prolonging its use time. Further reducing the need to frequently replace the sticking part brings convenience to patients and medical staff.

[0018] As a preferred scheme of the utility model, the sticking layer, the bacteriostatic layer and the waterproof layer are connected through an adhesive.

[0019] The adhesive connects the adhesive layer, the bacteriostatic layer and the waterproof layer, and the adhesive can tightly connect the adhesive layer, the bacteriostatic layer and the waterproof layer together to form a stable overall structure. The firm adhesion can ensure that the patch does not easily delaminate or fall off during use, thereby maintaining the integrity and stability of its function. The bacteriostatic layer connected by the adhesive can ensure that the bacteriostatic layer is tightly attached to the adhesive layer and the waterproof layer, reducing the possibility of bacterial growth between the layers. This helps to enhance the antibacterial effect of the patch and reduce the risk of infection.
