Description
Technical Field
[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a portable arm sleeve for an intravenous pain pump. Background Art
[0002] The pain pumps commonly used in hospitals at present are composed of three parts: a liquid bottle, a flow controller, and a thin connecting tube connecting the two. When the flow controller is connected to an intravenous indwelling needle through another connecting tube, there will be a situation where three devices are mixedly connected by two thin tubes. When a patient uses the pain pump, they need to find a place to place the liquid bottle and the flow controller by themselves (such as in a clothes pocket, beside the hospital bed, etc.). This often causes dragging among the three when the patient moves, making it very inconvenient to move, and even often causing the fixed indwelling needle to fall out, and having to be re-injected. Moreover, when the patient gets out of bed and moves, it is not convenient to observe the remaining amount of the liquid medicine, and it is not convenient to adjust the flow controller and control the pain at any time.
[0003] Currently, during the use of the existing portable arm sleeve for an intravenous pain pump, due to the various shapes, volumes, and sizes of the liquid bottles on the market, when placed inside the placement bag of the arm sleeve, the liquid bottle cannot be fixed, resulting in the situation of the liquid bottle falling, thus pulling the pipeline and causing harm to the patient. Therefore, we propose a portable arm sleeve for an intravenous pain pump. Content of the Utility Model
