According to the British BBC, a "painless vaccine patch" has passed Phase I clinical trials (safety test) in the human body, and the results were published in the latest issue of the medical journal The Lancet. The researchers said that there are 100 tiny needles on the patch that can penetrate the surface of the skin and can be used to vaccinate the flu, just as effective as a normal flu shot.
The patch is only a few centimeters in diameter and has a small, hair-like needle embedded in the center.
A while ago, the “smart insulin patch†developed by the Chinese scientist Gu Yu’s team received a $5.8 million investment, triggering a good time for diabetics without the need for needle injections of insulin.
This is not the case, in addition to the "smart insulin patch", scientists have also developed a "painless vaccine patch." This means that hundreds of millions of children will no longer be afraid of injections when vaccinated, and vaccines can be imported into the skin through this new type of painless patch.
Needle, goodbye!
According to the British BBC, this "painless vaccine patch" has passed Phase I clinical trials (safety test) in the human body, and the results were published in the latest issue of the medical journal The Lancet. The researchers said that there are 100 tiny needles on the patch that can penetrate the surface of the skin and can be used to vaccinate the flu, just as effective as a normal flu shot.
Unlike standard flu vaccines, it does not need to be kept in the refrigerator, which means that pharmacies can easily store them on the shelves for people to buy. Therefore, this painless, disposable vaccine patch is expected to reduce the need for needle injection.
Most volunteers say they are more inclined to this painless patch than injections.
Researchers involved in the study came from Emory University and Georgia Institute of Technology, both of which were funded by the National Institutes of Health (NIH). According to Prof. Prof Mark Prausnitz, the lead researcher, there is no difference in the preventive effect between this vaccine and the general vaccine, but it does not make the fluster feel pain: the general vaccine is injected intramuscularly, and this smart vaccine enters through the surface of the skin. human body. Currently, there is already a company that wants to obtain authorization for this technology.
During the clinical trial, the researchers performed a common vaccination on some of the 100 volunteers, while others used patches (20 minutes on the wrist). As a result, most people report that the use of patches is painless, but some people have minor side effects - redness, itching and tenderness in the skin, but these symptoms will be fine in a few days.
Easy to use
Dr. Nadine Rouphael from Emory University said that although this “painless vaccine patch†has been approved by the FDA for widespread use, it will take several years of further clinical trials, but “painless patch†is the future vaccination. trend. In the near future, we can immunize at home, at work, go to the pharmacy to buy a vaccine, or buy it online. This is a “subversion†way to prevent immunization.
In addition, on the one hand, after the use of the patch, it can be thrown into the trash can because it disappears, and it does not need to be treated as medical waste; on the other hand, it can be safely stored in an uncooled environment for up to one year. This is very useful in developing countries.
John Edmunds, an infectious disease specialist at the London School of Health, said that although the UK has introduced a nasal spray flu vaccine for children who don't like needles, the study opens up a better way to vaccinate.

The DVR 1080P, also called the Digital Video Recorder/ Digital Video Recorder 1080P/ 1080P DVR CCTV/ 1080P DVR Devices/ 1080P DVR for Security Cameras/ 1080P DVR Amazon, refers to that the resolution of the DVR is 1080P.
So what does DVR 1080P mean?
1080P, the letter "P" also called the Progressive Scanning, is a video display format. 1080P is the highest level of the high-definition TV format standard formulated by the Society of Motion Picture and Television Engineers (SMPTE), whose effective display format is 1920×1080.SMPTE. There are 1080P.1080I.720P(letter "i" means interlace; letter "p" means progressive; the number 1080 and 720 means that there are 1080 or 720 horizontal scan lines in the vertical direction) respectively according to the difference of the digital TV scan line. 1080P is that display format in which the clear display can achieve the resolution of 1920×1080 with the progressive scan way, which is the perfect combination of the digital TV and the computer technology.
What about the application of 1080P in security and protection field?
The typical reprensentation is the ACUTElogic Full HD Camera Module 1080P/30FPS.
The Full HD 1080P Integrated Camera Module ACUTElogic PE1005S series with a highly sensitive 1/2.5-inch 5-megapixel CMOS Sensor, by the most advanced 3A (AWB/AE/AF) image processing technology in the world, can reach the full Dynamic full HD (1920x1080/30P) video image effect. Meanwhile, the advantages of the integrated high-precision 10x optical lens, light weight (only 57g), small size (6cm*4cm*3cm), low power consumption (800mW) and so on, has made the Full HD 1080P Integrated Camera Module ACUTElogic PE1005S series the integrated camera module of the full HD 1920X1080/30P output with the smallest size, lightest weight, and lowest power-consumption. The specific performance is the fast autofocus, vivid color reproduction, high definition, excellent performance the wide dynamic range, low illumination, Anti-shake, macro camera and so on, which makes this module fully meet the using requirements in a variety of conditions, and has been widely used in the high-definition security monitoring, the high-definition video conference, the high-definition medical imaging, the high-definition multimedia teaching and other industries.
