Medical fluid injection method and medical fluid injection system

Abstract

The invention discloses a medical fluid injection method and a medical fluid injection system.The injection method comprises the steps that S1, feature information of a patient is obtained in a non-manual input mode, and the feature information comprises an examination part to be subjected to radiography and further comprises individual information of the patient; S2, generating a two-dimensional code or a bar code according to the feature information, and printing to obtain a paper label; S3, pasting the label on a needle cylinder; S4, reading label information on the needle cylinder through a code scanner; S5, the code scanner inputting the read label information into a control system of the injector, the control system comprises a processor and a database, a plurality of injection schemes are pre-stored in the database, and each injection scheme comprises a feature information group and an associated injection parameter model; and S6, the processor calls an injection scheme matched with the feature information of the current patient from the database according to a preset rule. According to the system, the workload of repeatedly inputting parameters by technicians can be effectively reduced, and the injection scheme can be intelligently matched.

Description

Technical field [0001] The present invention relates to the field of medical equipment, and more particularly to a medical fluid injection method and a medical fluid injection system. Background technique [0002] The high pressure injection system is a syringe for survive in which the contrast agent injection is performed in angiography, and is injecting a contrast agent to enhance the tissue contrast, improving the degree of disease resolution and diagnosis. [0003] The operation steps of the existing syringe-based high pressure injection system are: 1 to the needle tank to the high pressure syringe; 2 Insert one end of the suction pipe into the front end of the syringe; 3 insert the other end of the suction pipe into the liquid container; 4 By pressing the push rod pulling the needle piston of the high pressure syringe to pull the syringe inside the syringe; 5 The system automatically determines whether the air is residual in the syringe and discharge it; 6 connect the patien...

AI Technical Summary

Problems solved by technology

[0005] First, the injection dose of contrast agent is determined entirely by technicians or nurses. If the dose is too low, it will affect the quality of contrast imaging, and if the dose is too high, it will cause unnecessary harm to the human body. high requirements;

[0006] Second, the technician or nurse needs to manually input the injection parameters, which not only increases the workload and reduces the inspection efficiency, but also has the risk of input errors, and it is difficult to correct the wrong input;

[0007] Third, for example, the contrast agents of different examination sites such as the brain, heart, liver, and lungs are quite different. Generally, technicians do not have the ability to conduct medical research on different examination sites. Therefore, it is necessary to set appropriate contrast agents for different examination sites. Injecting parameters is a very difficult task;

[0008] Fourth, the injection of contrast agent (including different injection doses and injection flow rates) will have an impact on contrast imaging, but this impact, especially the negative impact, cannot be fed back to adjust and improve the injection plan;

[0009] Fifth, although it has been realized that the corresponding contrast agent injection plan needs to be adjusted according to the height of the individual patient, or the injection plan is given by the doctor, it is still necessary for the technician or nurse to manually input the corresponding parameters
