[0002] Intravenous infusion is a method of injecting a large amount of sterile liquid, electrolytes, and drugs into the body through the veins by using the principle of atmospheric pressure and liquid static pressure. Injecting a large amount of liquid, electrolytes, or blood through the veins is called intravenous infusion. Due to the differences in the injection site and infusion, it can be divided into peripheral intravenous infusion, central venous infusion, hypernutrient infusion (TPN), and blood transfusion.
[0003] However, the prior art still has the following problems:
[0004] First, the infusion device for fixing the infusion catheter in the prior art is not easy to be fixed and installed. Usually, it is simply placed somewhere and then the infusion catheter is reinforced. This fixing method may become loose due to the movement of the patient's body, and the fixing effect is not good. If the device for fixing the infusion catheter can be fixedly installed on a bracket or a certain position, the effect of fixing the catheter can be improved.
[0005] Secondly, the infusion device of the prior art is not convenient for fixing the infusion catheter. Since the infusion catheter is made of soft material, it will bend during use. It is necessary to ensure high stability during the infusion process, otherwise it may affect the normal progress of the infusion work. If it cannot be fixed, there will be safety hazards for patients.
[0006] In view of the above problems, the inventor proposes an infusion device capable of fixing an infusion catheter to solve the above problems. Utility Model Content
