Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a frame device used for calibrating medical injection pumps and infusion pumps. Background Art
[0002] Syringe pumps and infusion pumps are medical devices used to inject medicine or nutrient solutions. Syringe pumps use a lead screw to convert the rotation of a motor into linear motion, thereby pushing a piston to inject the medicine. Infusion pumps are used to control the speed of large-volume drug injection. Both require flow rate calibration during use to ensure the accuracy of the injection volume and flow rate of the medicine bottle.
[0003] The existing frame device used for calibrating medical syringe pumps and infusion pumps only has one set of experimental equipment. When detecting the actual flow rate and flow rate of the syringe pumps and infusion pumps, errors are prone to occur, and the detection accuracy cannot be guaranteed. As a result, the flow rate and flow rate of the syringe pumps and infusion pumps cannot be calibrated. In addition, the existing frame device is inconvenient for medical staff to push and adjust the height. Therefore, we propose a frame device for calibrating medical syringe pumps and infusion pumps. Utility Model Content
[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a frame device for calibrating medical injection pumps and infusion pumps. The frame device has a reliable instrument calibration unit and can detect the flow and flow rate data of both the injection pump and the infusion pump. By setting up three groups of identical detection devices and then manually checking them, the accuracy of the detection can be improved, so that it can be compared with the initially set injection value to calibrate the flow of the injection pump or the infusion pump. The frame device also has a reliable use control unit, which can facilitate medical staff to push the frame device to move, and can conveniently control the lifting and lowering of the placement table and the bottle hook, thereby improving the practicality of the frame device and effectively solving the problems in the background technology.
[0005] To achieve the above-mentioned object, the present utility model provides the following technical solutions: a frame device for calibrating medical syringe pumps and infusion pumps, comprising a placement table, an instrument calibration unit, and a use control unit;
