Problems solved by technology
[0003] Existing schemes generally use the combination of optocouplers to identify the size of the syringe with a movable visor. In this method, the number of optocouplers combined, the installation accuracy and the installation structure will all affect the identification results. Therefore, Often lead to misidentification of the size of the syringe
In addition, the existing solution does not calibrate the size of the syringe, which further reduces the accuracy of recognition

The invention relates to a syringe specification identification and calibration system for an injection pump and a method thereof. The syringe specification identification and calibration system comprises a driving device, an identification device, a calibration device and a main control device, the driving device outputs a driving signal according to the control signal output by the main control device to drive the needle cylinder to inject and returns a monitoring signal; the identification device detects the specification of a needle cylinder and outputs a specification detection signal; the calibration device detects the position of the needle cylinder to output a position detection signal when calibrating the specification of the needle cylinder; when the main control device calibrates the specifications of the needle cylinders, the main control device obtains a specification corresponding relation table of the specifications of the needle cylinders and the specification detection signals according to the position detection signals and the identification device; the main control device also identifies the specification of the needle cylinder according to the specification detection signal and the specification corresponding relation table when identifying the specification of the needle cylinder. The calibration can be carried out before syringe specification identification, the identification accuracy is improved, a non-optocoupler identification mode is adopted, the accuracy is higher, and the reliability is better.
Description
technical field [0001] The invention relates to the field of medical equipment, and more specifically, to a system and method for identifying and calibrating syringe specifications of syringe pumps. Background technique [0002] Syringe pumps have been widely used in clinical rehabilitation and treatment. They belong to infusion equipment or appliances in operating rooms, emergency rooms, and treatment rooms. There are higher requirements to ensure that the flow and velocity of the liquid injected into the patient's body meet the expectations and ensure the safety of clinical use. The size of the syringe barrel is the main component that affects the injection speed and dose of the syringe pump. When injecting the liquid medicine, the specification of the syringe barrel needs to be identified. [0003] Existing schemes generally use the combination of optocouplers to identify the size of the syringe with a movable visor. In this method, the number of optocouplers combined, t...
