Description

Technical Field

[0001] The utility model relates to the technical field of micro-infusion pump fixing frames, in particular to a micro-infusion pump fixing frame. Background Art

[0002] A micro-injection pump is used to accurately, microscopically, uniformly and continuously pump a small amount of liquid medicine into the human body, and is convenient to operate. The drug concentration and speed can be adjusted at any time according to the needs of the condition. In actual use in hospitals, the micro-injection pump is often fixed on an infusion stand or placed on a bedside table, a bedside chair, etc. When the patient turns over, due to the short length of an extension tube, the movement is restricted. If two extension tubes are connected, it is too long and easy to drag to the ground, which does not meet the requirements of hospital infection control and poses a great potential safety hazard. If it accidentally falls to the ground, it will cause damage to the micro-injection pump. During the use process, a micro-infusion pump fixing frame is needed to fix the micro-infusion pump.
