Intravenous infusion is one of the most commonly used clinical treatments. However, for some special patients, when infusion, appropriate infusion rate must be set according to the difference between the drug and the patient's condition. For example, chemotherapy for cancer patients requires the drug to be infused at a constant rate. The chemotherapeutic agent is injected evenly and continuously by adjusting the speed and time of input, which not only achieves the best effect of chemotherapy, but also minimizes the side effects of chemotherapy drugs. People suffer from pain and also need to inject them with a certain amount of insulin at a certain rate.
These special patients require high infusion volume and flow rate, and the traditional manual control of the flow rate has not been able to adapt to these special patients and there are certain risks. The medical syringe pump and the infusion pump can better control the flow rate and flow rate of the infusion, and better protect the patient for the auxiliary clinical infusion.
In recent years, the use of medical syringe pumps and infusion pumps has increased greatly with the improvement of hospital configuration equipment in China. At present, infusion pumps have been widely used in ICU, CCU, operating room, emergency department, gynecology, pediatrics and other departments. Medical syringe pumps and infusion pumps are typical measuring instruments. The flow control requirements for infusion fluids are very precise. Subtle errors in measurement may have a great impact on the patient's treatment effect and safety. To ensure that their measurement accuracy can ensure the accuracy of infusion accuracy in order to effectively protect patients.
The infusion pump belongs to the peristaltic pump machinery and is a typical small flow metering instrument. It will inevitably bring error when it is used for a long time. In addition, the syringe pump and the infusion pump have strict requirements on the material of the infusion tube. Different materials may cause the thickness of the infusion tube wall to be different. This may also affect the volume measurement of the infusion tube, thereby causing errors. In practical applications, the infusion rate is often lower than 100 ml/hour. Infusion accuracy is generally controlled within 10%, and in special cases it is 5%.
In order to ensure that the infusion pump has sufficient infusion accuracy, many regions have carried out infusion pump testing projects, and the infusion pump tester is used for quality control and calibration of various infusion pumps. Before 2010, the state has not yet issued the verification procedures for infusion pump testers. At the same time, the traceability of infusion pump testers has become an urgent problem to solve.
Scientific workers specializing in medical metrology research in China have conducted research and analysis on the status of domestic medical syringe pumps and infusion pumps. At the same time, they have carried out research work on calibration devices for infusion pump testers and established calibration methods for infusion pump testers. Provides technical support for the traceability of infusion pump values ​​in metrology and technical institutes of various provinces and cities, making the calibration results of infusion pump detectors accurate and reliable.
The research group established a calibration device for the infusion pump tester, established a calibration method for the infusion pump tester, and completed the “calibration specification for medical syringe pumps and infusion pumpsâ€. It has been officially implemented. This specification has made uniform specifications and requirements for the calibration of metrological indicators such as medical infusion pumps, infusion pump infusion flow, occlusion alarm pressure threshold, and patient leakage current. The establishment of the infusion pump tester calibration device and the implementation of calibration specifications have improved the traceability system of the injecting pump and infusion pump in hospitals, providing technical support for the traceability of infusion pumps in the national metrology institutes, making the infusion pump tester The calibration results are accurate and reliable.
