[0002] Intravenous infusion is a method of injecting a large amount of sterile liquid, electrolytes, and drugs into the body through the veins using the principles of atmospheric pressure and liquid static pressure. Injecting a large amount of liquid, electrolytes, or blood into 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] During intravenous infusion, for patients who need long-term infusion, most patients may place their hands on their legs or in front of their bodies for a long time, which can easily cause arm numbness. In addition, if the infusion environment is relatively cold, the temperature of the medicine is often low, which can make patients feel cold arms and cause discomfort.

[0004] Based on the above, the inventors have found the following problems: existing hand placement support devices often have single functions and poor adaptability, and these devices often lack consideration for the comfort of the infusion process and cannot effectively alleviate the discomfort of patients during the infusion process.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and an intravenous infusion hand placement support device is provided, in order to achieve a more practical purpose. Utility Model Content
