Description

Technical Field

[0001] The present invention relates to the technical field of infusion metering, and in particular to an adjustable infusion metering alarm device and method. Background Art

[0002] In modern medical care, intravenous infusion is a widely used treatment method for delivering drugs, replenishing body fluids and providing nutrition. However, in actual operation, the safety and accuracy of the infusion process has always been one of the difficulties in nursing work. Nursing staff usually roughly estimate the infusion volume by observing the number of drops and liquid level with the naked eye. This traditional manual monitoring method has great uncertainty. Especially in a busy nursing environment, it is difficult to monitor the progress of infusion in time, which can easily lead to the infusion volume exceeding the doctor's order, thus posing a potential threat to the patient's health.

[0003] Existing infusion metering devices mostly use mechanical metering or single sensing technology, and their functions are relatively simple, which cannot meet the precise monitoring needs in complex medical scenarios. These devices are easily interfered by external factors, such as changes in ambient light, liquid transparency, or dropper installation errors, resulting in insufficient metering accuracy. In addition, most devices cannot flexibly set liquid volume alarm thresholds or adjust drop coefficients according to the patient's personalized infusion needs, and lack sufficient adaptability. At the same time, some equipment is complex to install and cumbersome to operate, and it is difficult for nursing staff to complete calibration or adjustment in time in an emergency, which affects the actual use of the equipment.

[0004] The lack of intelligence is also a major problem with existing infusion metering devices. Many devices cannot be combined with artificial intelligence technology to achieve dynamic adjustment, and it is difficult to cope with the challenges caused by changes in liquid viscosity, number of drops or environmental interference during the infusion process. At the same time, most of these devices lack real-time alarm functions and cannot promptly remind nursing staff to intervene when the infusion volume is about to reach the set threshold, thereby increasing medical risks. For example, for certain treatment scenarios that require strict control of the infusion volume, such as chemotherapy or anesthetic infusion, excessive amounts may cause serious toxic reactions. In addition, rapid or excessive infusions may also put a burden on the patient's heart and kidneys, and even cause life-threatening complications such as acute pulmonary edema. In summary, the current infusion monitoring methods are insufficient in terms of accuracy, convenience and intelligence. Summary of the invention

[0005] In view of this, the present invention provides an adjustable infusion metering alarm device and method, which is used to solve the problems of inaccurate manual monitoring, single equipment function, and untimely alarm during the infusion process, improve the safety and efficiency of the infusion process, and effectively avoid the risks to patient health caused by excessive infusion or delayed nursing.

[0024] Optionally, step 4 includes:

[0025] If the total volume of the infused liquid is greater than or equal to the preset threshold, the alarm module will issue an audible and visual alarm prompt; the audible and visual alarm prompt includes a sound prompt and an LED flashing.
