Syringe parameter calibration method, calibration device and computer storage medium

Abstract

The embodiment of the present invention discloses a parameter calibration method for a syringe, a calibration device and a computer storage medium, which are applied to the calibration device. The calibration device includes a syringe pump and a distance measurement unit. The specific calibration step includes receiving a calibration that acts on an operation interface of the syringe pump. Start command, start the stepper motor according to the calibration start command, so that the stepper motor drives the push block to push the piston core rod of the target syringe, and obtains the push block collected by the distance measurement unit Push the distance that the piston core rod of the target syringe moves, and obtain the real-time pulse of the stepper motor, according to the preset target speed, the cross-sectional area of ​​the target syringe, the real-time pulse and the distance that the push block moves , obtain the pulse frequency of the syringe pump, calibrate the injection parameters of the target syringe according to the pulse frequency of the syringe pump, and effectively improve the accuracy of syringe calibration through the combination of the syringe pump and the distance measurement unit.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a parameter calibration method of a syringe, a calibration device and a computer storage medium. Background technique [0002] There are more than 8 default brands of syringes, and each brand has a total of 6 capacity specifications with different cross-sectional areas, such as 2ml, 5ml, 10ml, 20ml, 30ml, 50 or 60ml. The factory debugging of the existing calibration scheme requires accuracy calibration of 6 specifications of various brands to ensure that the injection accuracy of the syringes using the above brands meets the technical requirements of the factory. The precision calibration takes at least 48 minutes, which is inefficient for mass production and consumes a lot of human and material resources. [0003] In addition, the existing calibration scheme has objective deviation, which will lead to the inaccuracy of the final calculated target frequency. Therefore, there i...

Problems solved by technology

The ex-factory commissioning of the existing calibration scheme requires precision calibration of 6 specifications of various brands to ensure that the injection accuracy of the above brands of syringes meets the technical requirements of the factory. If a single machine needs 1 minute to calibrate each specification, it will complete all brands of a machine. Accuracy calibration takes at least 48 minutes, which is inefficient for mass production and consumes a lot of human and material resources

[0003] Moreover, there are objective deviations in the existing calibration schemes, which will lead to inaccurate final calculated target frequencies. Therefore, there is an urgent need for a syringe parameter calibration scheme with high flexibility and high accuracy.
