Definition
Infusion alarm: the popular title of transfusion monitor. On June 10, 2004, the State Food and Drug Administration in "on Article 10 of the gingivitis flushing products classification is defined in terms of the notice" (State Food Drug armed [2004]321) of transfusion monitor definition is: "medical transfusion monitor for monitoring the status of the infusion, liquid medicine stop drop or reaches the set value can be issued when the tip, as a class I medical device management.
Function and significance
Hope to solve the infusion monitoring of a lot of people, they all had hospital infusion or to accompany bed infusion experience, deeply need a transfusion is nearing completion in reminding device (alarm). Therefore, there are media reports on the solution of the infusion monitoring (alarm) small inventions of the news, CCTV has specifically held a variety of infusion alarm small inventions. The inventors have both professional personnel, and some 10 year old pupils and over seventy years of age of octogenarian.
The positive significance of the infusion monitor has three points: first, the patient has the need, two is to help the nursing staff, three is the national food and drug administration to support.
1, the patient needs. Having had hospital infusion or to accompany bed infusion experience, most of them have such an experience, that is, because the infusion, want to sleep can not sleep, to accompany the bed to go and not go away. Possess of some of the hospital random survey, more than 80% of hospitalized patients or peichuang families have the demand of infusion monitoring (alarm).
2, to help the nursing staff. In recent years, although the increasingly high quality of nursing staff, service quality is getting higher and higher, service level is getting higher and higher, but rely on manual can not solve a problem, that is to determine completion of the infusion time, although nursing personnel to patrol, often can only be liquid and not completely lost, early replacement under a group of infusion fluid, or removal of the infusion. The result is the energy of the care staff, and some of the waste liquid.
3, the State Food and drug administration to support. Based on the multi demand, State Food and Drug Administration on 10 June 2004. "On gingivitis flushing products classification is defined in terms of the notice" (State Food Drug armed [2004]321), of transfusion monitor should be ownership of medical device classification, function is defined, paving the way for infusion monitor the development and medical device registration card.
Related technology
There are a lot of patents involved in the monitoring of infusion, the website of the National Bureau of intellectual property, and the patent of the transfusion monitoring (warning) are over 600.. But many of these patents are difficult to form the product, some patents too extensive, some patents too complicated, some of the high cost of production, some patents impractical.
There are three kinds of technology of transfusion monitor application: one is photoelectric principle, two is weighing principle; three is the capacitance principle. In addition, through the principle of electrode conductivity, but the liquid pollution, can not be applied.
The photoelectric principle of transfusion monitor, early is infusion monitor clamping in the infusion of the dropping bucket, or holding in the mouth of the infusion bottle, these methods have effect, the detection characteristics of relatively extensive. Now the technology has been realized on the transfusion tube, the detection of the fine has been greatly improved. For example, the Beijing GODEX Rui Seoul Technology Co., Ltd. R & D infusion monitor, with advanced technology, reminding reliable, simple operation, compact and convenient, affordable and so on. Infusion monitor again Shenzhen lonbon science and technology limited company research and development, the electric power supply, and can automatically stop liquid.
Infusion monitor for weighing principle (or buckle, measuring principle of weight), the spring balance or pressure sensor according to the drug weight changes to determine after the physic liquor is transfused or not, and also the need for adjusting initial parameters according to the different weight of empty infusion bottle. Although the structure is simple, but the existence of extensive detection, large size, and accuracy, reliability and adaptability is not high enough.
For the transfusion monitor, the capacitance principle has the weak anti-interference ability, and has less application..
Status quo and features
Over the years there have been many near infusion monitor (alarm) products available, the use of technology is the basic problems such as before the three. Many products exist: the weighing principle (or buckle, measuring principle of weight) R & D transfusion monitor, there are defects of bulky, extensive detection, accuracy is not high. Two is that some products are too complex, lack of skills, and then lead to a slightly larger size, high cost, the price is too expensive. Three is the product application main object positioning is not accurate.
The newly developed infusion monitor, the above three aspects of the problem is solved well. Is not only the main object of the application of accurate positioning, and the volume is small, easy to operate, the price is very low, and can cooperate with the use of headphones will not interfere with others, get the common recognition of doctors and patients.
Future development
According to the national food and Drug Administration for the definition of the infusion monitor, infusion monitor (alarm) just play a role, and its automation, intelligent degree still need to improve. If the special wireless call system is special, it can constitute the intelligent transfusion monitoring information management system.. Application of the system, nurses in nurse station can control the infusion of all wards in the ward, to provide timely and effective care for patients and greatly improve the management level of the hospital intelligent, networking, standardization.
