Everyone knows that Theranos, founded by the big-eyed beauty Holems, is currently in deep technical crisis. The US FDA and CMS issued more than 100 reports, questioning its claimed rapid blood detection technology for fingertips. However, before the Holems beauty completely announced its technical "black box", we were really uncomfortable with the technical core of Theranos products. But looking at the cutting-edge technology in the field of rapid detection, the technology core of Theranos products should be the combination of microfluidic chip technology and sensors, and some technologies can be improved to make it possible to detect with fingertip blood. Let's not say whether Theranos sells dog meat, but the microfluidic chip is really the new favorite of current researchers.
The most closely integrated with microfluidic chip technology is the medical industry , especially the POCT industry. The full text of POCT is point-of-care testing, which is instant detection, and more vividly, bedside detection. He is an emerging segment of in vitro diagnostics. The concept of POCT was proposed in the 1980s and 1990s. The speed of technological development and marketization is very fast. Today, the global market is over 10 billion US dollars, and it is increasing at a rate of more than 10% per year.
As the market demands become higher, POCT technology is also moving toward higher (efficiency), faster (faster), and stronger (big), and the technology change is leading to the application of microfluidic chips. The microfluidic chip can completely integrate all the functions of a skyscraper into a small paper box, and the accuracy is greatly improved, and the accuracy is also guaranteed. This interdisciplinary and multi-disciplinary chip technology has already entered the market.
New weapon for blood tests - instant micro blood test
Laboratory chip technology, also known as micro-analysis system, can detect hemoglobin, electrolytes, blood oxygen, heart index, etc. by detecting trace amounts (2, 3 drops) of whole blood in just a few minutes. The project will escort the patient for surgery or further health care as soon as possible.
Abbott i-STAT system portable device
It seems like a fantasy - how many times can you accurately detect the above indicators and form a document? Now there is a product: Abbott’s i-STAT system. It is based on laboratory chip technology and was officially launched in 2011 for emergency, rescue and family doctors. It integrates the inspection and instrumentation of the entire inspection laboratory into a test system, which is about the same size as the ipad, so that it is truly portable.
The domestic equipment includes portable instruments, portable printers, bases, simulators and reagent cards. The set price is more than 100,000 yuan. The portable instrument is light in weight and almost equal to ipadAIR, but it can store thousands of inspection reports. The printer interconnect will report immediately.
Abbott i-STAT System Test Card
In addition to portable instruments, the i-STAT system is the most important reagent card. It can be said that it is the highest form of microfluidic chip display. Different microchips are arranged in different areas of a small test card. Cards are used to prevent cross-contamination. The practicality of the reagent card is even more powerful. It can detect blood gas indexes such as blood coagulation, electrolytes, blood pH value, blood oxygen and blood carbon dioxide concentration in emergency first aid; it can also test blood biochemistry, myocardial markers and other health indicators, which is convenient for family doctors.
