System for monitoring and controlling medical transfusion speed based on machine vision

Abstract

The invention belongs to the field of medical device and provides a medical infusion speed monitoring and control system based on machine vision. The invention comprises an image collection device, a parameter input device, a data processor, a data display device, a dripping speed control device and an alarm prompting device. The data processor comprises an image processing module, a data display module, a data analyzing module, an alarm prompting module and a dropping speed control module. The invention uses an image processing method for calculating the infusion speed, which is stable and reliable. The invention solves the problems of inaccurate detection and complex operation caused by different infusion bottle / bag weight when detected using weighing principle and outside radiation source interference in the infrared light detecting method universally applied currently. The system is capable of automatically adjusting the infusion speed so that the infusion speed is equal / close to the inputted expected dropping speed. The invention is also capable of alarming to the abnormal condition occurs in non medical solution or / and other infusion process, which relieves the pain for patients, reduces the workload for medical staff and decreases the occurrence of medical malpractice.

Description

technical field [0001] The invention belongs to the field of medical equipment, and specifically relates to a machine vision-based medical infusion speed monitoring and control system. The device can be used in conjunction with medical infusion equipment, and is an auxiliary medical equipment for hospital infusion. Background technique [0002] Intravenous infusion is a commonly used drug administration technology in clinical treatment. It uses the principle that the liquid pressure in the infusion tube is stronger than the liquid pressure in the human vein, and the medicinal liquid is directly injected into the human vein through the catheter. During the infusion process, the speed at which the liquid enters the patient's vein directly affects the therapeutic effect of the drug on the patient. If the speed is too fast, the patient may be poisoned, and in severe cases, it may lead to heart failure; if the speed is too slow, the dose may not be enough. Or prolong the infusion...

AI Technical Summary

Problems solved by technology

At present, there are also many patents on medical infusion speed detection and flow control. For example, the patent document with the publication number CN2875460 uses an infrared light transceiver device to detect the liquid by using the principle of refraction of light in the liquid. This detection method has the advantages of The advantages of easy implementation, but the infrared light transceiver device is easily interfered by external radiation sources, and the installation of infrared detection equipment on the Murphy's dropper requires high technology and high requirements for installation accuracy

Once the dropper is tilted, the sensor cannot accurately detect the falling drop

In addition, there are some patent documents that use the principle of weighing as the current limiting device. Although the principle of this method is simple and easy to implement, due to the different materials and processes used in the infusion bottles and infusion bags produced by different manufacturers, the weight of the method may vary. There is a difference, which has a certain impact on the measurement accuracy

If the weight parameter needs to be initialized every time it is set, it will increase the complexity of the operation

In addition, there are also some devices such as infusion pumps on the market, but due to their high price, most of them are limited to use in high-end intensive care units (ICU) or operating rooms (OR)
