Intravenous infusion therapy is a common treatment method for diseases. Intravenous infusion generally involves piercing the infusion needle into the veins of the patient's hands or feet. For some critically ill patients who need long-term intravenous infusion or obese people who are difficult to find blood vessels 1. Infants and young children often use intravenous indwelling needles for infusion to avoid the pain and inconvenience caused by multiple punctures. However, for infants or restless people, due to excessive activities, the indwelling needle often shifts and falls off, which shortens the indwelling time of the indwelling needle, and the next time the intravenous infusion has to be punctured again, thereby increasing the patient's misery.

In the prior art, there are mainly two ways to fix the indwelling needle: one is to fix the indwelling needle with a transparent applicator, directly attach the transparent applicator to the indwelling needle, and rely on the adhesive force of the transparent applicator to fix the indwelling needle. The indwelling needle is fixed; the second is to use a venous indwelling needle fixing belt to fix the indwelling needle. The middle part of the current venous indwelling needle fixing belt is provided with a transparent applicator, and the situation at the puncture site can be easily observed through the transparent applicator. Timely detection of abnormalities such as redness, swelling, and paleness of the skin at the puncture site.

However, the hands and feet of infants are prone to sweating. If the indwelling needle is fixed by the above-mentioned first method (attaching the transparent applicator to the indwelling needle), it is easy to be affected by the sweat of the infant, resulting in poor adhesion of the transparent applicator. In addition, for the indwelling needle fixing belt in the second method above, the transparent applicator is directly connected to the body of the fixing belt, and the tightness of the fixing belt directly affects the pressure of the indwelling needle by the transparent applicator. , the transparent applicator is attached to the indwelling needle, and then the body of the fixing belt is pulled to wrap around the patient's arm or ankle. If the body of the fixing belt collapses too tightly, the transparent applicator will be pulled to over-press the indwelling needle, which may cause Abnormal phenomena such as redness, swelling, and paleness of the patient's skin; on the contrary, if the body of the fixation belt collapses too loosely, it cannot fix the indwelling needle well.
