The invention discloses an automatic calibration system for pressure of an injection pump. The automatic calibration system comprises an injector used for injection, a pressure detection unit and an injection pump; the pressure detection unit is connected with the injector and is used for detecting a pressure value of the water outlet end of the injector; the injection pump comprises a mechanical action part and an electric control part; and the electric control part controls the injector to inject according to the prestored corresponding relation of pressure values and voltage values, receives the voltage values output by a pressure sensor under the continuous pressure values during injection of the injector, and stores the corresponding relation of the pressure values and the voltage values. The automatic calibration system for pressure of the injection pump replaces the prestored corresponding relation of pressure values and voltage values with the obtained corresponding relation of pressure values and voltage values, and stores the obtained corresponding relation, so that calibration of preset injection parameters of the injector and practical injection parameters of the injector of the injection pump is realized, and the problems of low efficiency and incomplete data of manual calibration are solved. Moreover, the invention also provides an automatic calibration method for pressure of the injection pump.
Description
technical field [0001] The invention relates to the field of medical equipment, in particular to a method and system for automatically calibrating the pressure of a syringe pump. Background technique [0002] In medical and industrial equipment, syringe pump equipment is often used. The syringe pump pushes the syringe through its mechanical device to achieve smooth and pulse-free liquid transmission. During the transmission process, the output pressure of the injection liquid output by the syringe And output speed has higher requirements. Because the syringe is controlled by the syringe pump, during the production or application of the syringe pump, it is necessary to adjust the mechanical device of the syringe pump and the driving device used to drive the mechanical device to achieve accurate output pressure or output speed. [0003] The current pressure calibration scheme requires manual monitoring of the injection process and manual collection of pressure data. The basic...
