Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an elbow fixing device. Background Art

[0002] Intravenous infusion is a treatment method that directly injects a large amount of sterile solution or medicine into the vein. Intravenous infusion can correct water and electrolyte imbalance, increase circulating blood volume, improve microcirculation, and maintain blood pressure. It can also provide nutrition, promote tissue repair, and maintain positive nitrogen balance. It can also treat diseases. The sites of intravenous infusion are usually the back of the hand and the elbow. Because the elbow is prone to bending, especially elderly patients or drunk patients are not clear-headed and bend their elbows involuntarily. When the elbow is bent, the harder needle will pierce the elbow blood vessels. For intravenous infusion at the elbow, the infusion needle is usually a hose, but the patient's arm bending will cause the hose to bend, resulting in poor intravenous infusion. Currently, there is no device to fix the elbow for this scenario. Utility Model Content
