Photoelectric sensor based infusion medicine liquid identification device and method

Abstract

The invention discloses a photoelectric sensor based infusion medicine liquid identification device and method, and relates to the technical field of infusion monitoring. The device includes a body, and the body is connected to a top cover and provided with a dropper groove; a photoelectric sensor, a microcontroller and a battery are installed on the body; the photoelectric sensor is provided withan infrared emission tube and an infrared receiving tube and electrically connected to the microcontroller; and the battery is used for supplying power for the device. The method includes convertingthe influence of a medicine liquid drop growth process on infrared light intensity into an electric signal and performing storing; dividing monocyclic drop growth signals according to blank pipe threshold values and signal variation trend, and obtaining the characteristic peaks of medicine liquid in frequency domains through fast Fourier transform; and confirming the types of the medicine liquid through the comparison with the characteristic peaks of a database, and obtaining a reasonable infusion monitoring range through the table look-up of the database. Through the utilization of the deviceand the method, the types of the medicine liquid can be effectively identified, and the dripping speed of drops can be monitored.

Description

technical field [0001] The invention relates to the technical field of infusion monitoring, in particular to a photoelectric sensor-based infusion liquid identification device and method. Background technique [0002] Intravenous infusion is a common treatment method in clinical medicine. For specific patients, medicinal liquids or conditions, there are specific drip speed requirements for intravenous infusion. For example, sodium chloride, glucose, furosemide and other drugs require a drip rate of 5ml / min; drugs such as pantoprazole sodium and vinorelbine tartrate require a drip rate of 10ml / min; drugs such as Shuxuening and metronidazole require The dripping speed is 2~4ml / min. At the same time, during intravenous infusion, different drugs need to be diluted with specific injections to ensure stability. For example, pirarubicin hydrochloride is recommended to be used with 5% glucose injection, not suitable for sodium chloride injection. Use in solution; Cyclophosphamide ...

AI Technical Summary

Problems solved by technology

However, the above method can only detect the drop rate of the drug solution during the infusion process, and cannot identify the type of drug solution, and cannot monitor the drop rate in a targeted manner and give an alarm to the compatibility error of the drug solution, and cannot meet the requirements for adaptive dripping of a specific drug solution. fast monitoring needs

This makes it necessary to rely on nurses to conduct "three checks and seven pairs" and manually adjust the infusion set to avoid nursing errors in clinical work, which greatly increases the workload of medical staff and cannot completely eliminate the occurrence of nursing errors.
