Highlights of research and development of new foreign medical devices
It must be acknowledged that medicine has so far failed to provide effective cures for many diseases, such as the well-known Alzheimer's disease (also known as Alzheimer's disease), macular degeneration and many cancers. Therefore, it is very important to find out the signs of these diseases and preventive treatment as soon as possible to delay the development of the disease and improve the quality of life. In this regard, medical device companies at home and abroad have done a lot of work. Recently, foreign medical websites have reported some new medical device products that can play an important role in the prevention and treatment of diseases.
An instrument that can easily assess Alzheimer's disease
As the population ages in the world increases, the number of Alzheimer's patients continues to increase. The World Health Organization's special report on Alzheimer's has highlighted that Alzheimer's has become a major disease challenge facing the world. However, the reality is that the current accurate diagnosis and diagnosis of Alzheimer's disease depends mainly on experienced neurologists. The general diagnostic ability of the general practitioners is generally insufficient because of early Alzheimer's disease and other cognitive functions. There are many similarities between damage and emotional disorders. However, most patients do not go directly to the neurology department of a general hospital when they have early symptoms, but go to the community and primary health care institutions. This means that community doctors must improve their ability to diagnose Alzheimer's disease as soon as possible.
In response to this urgent need, researchers at Rochester, USA, have developed a medical instrument "COGNIVUE" that allows general practitioners and even experienced nurses to simply assess the risk of Alzheimer's disease. The medical staff only needs to press one of the opening keys of the instrument, and various flashing patterns appear on the display screen of the instrument. The old person can identify the content on the pattern, and the instrument can analyze and score according to the reaction of the elderly, and assist the judgment. The condition of Alzheimer's disease.
Skin film that monitors harmful gases
Researchers at the Royal Melbourne Institute of Technology have developed a new flexible, fully transparent film. This film looks unremarkable, but it is not an ordinary patch - it can not only monitor the concentration of hydrogen and nitrogen dioxide in the air, but also monitor the intensity of ultraviolet radiation, etc., for a variety of purposes.
According to foreign media reports, researchers at the Melbourne Institute of Technology have developed this flexible, fully transparent film using nanoscale zinc oxide particulate materials and sensors. The user only needs to attach it to the skin of any part. When the concentration of harmful gases such as nitrogen dioxide in the environment exceeds the standard, or there is too strong ultraviolet radiation, the nano-scale zinc oxide in the transparent film will change. It is opaque to remind people of environmental hazards.
New equipment for powerful and fast gravel
Due to changes in people's diet and other living habits, the incidence of stone disease is increasing, especially the incidence of gallstones, kidney stones, bladder stones is the most significant increase. Patients with stone disease are very painful at the time of onset, and sleep is difficult. Although medical equipment such as ultrasonic lithotripters have already appeared on the market, such products have the disadvantages of large volume, troublesome operation, and unsatisfactory effect on some stones.
Not long ago, Japan's OLYMPUS developed a powerful crusher "SPSE SYSTEM". According to reports, the working principle of the machine is to combine powerful pulsed mechanical waves with ultrasonic waves to crush large stones in the gallbladder and urinary system in a short time, and then pump the gravel out through the special catheter to achieve rapid speed. The purpose of the stone.
a helmet that helps overcome fear of heights
Many people are "fear of heights". They are afraid of climbing, climbing upstairs and overlooking the scenes under their feet. They are even more afraid to fly. This psychological barrier greatly limits the ability of the fear-high to adapt to work and life. To help the fearful people overcome this psychological barrier, two researchers at the Department of Electronic Technology at the University of California, Santa Clara, developed an original "TV helmet."
According to reports, after the fear of the person wearing the helmet on the head, the helmet's electronic eyepiece will automatically display a variety of scenes from the height overlooking the ground. Regular use of the helmet by the patient can gradually overcome the "heart disease" of fear of ascending. This kind of TV helmet is cheap to produce. In addition to helping the fear-high to overcome psychological obstacles, it can also be used for indoor training of new pilots - just change the settings in the TV helmet to sit in the ground training room. The new pilot "sees" the virtual runway and the buildings near the airport.
Test strip for detecting breast cancer with a small amount of urine
Breast cancer is one of the most serious cancers for women. However, the symptoms of early or even mid-stage breast cancer are not obvious, and many patients who come to the hospital have developed to the advanced stage of cancer and missed the opportunity for optimal surgical treatment. To help early detection of breast cancer in the clinic, researchers at the University of Freiburg in Germany set out to develop a simpler method for detecting breast cancer – just take a few drops of urine for a medical test to find out if you have breast cancer.
According to German researchers, some special RNA substances are produced during the metabolism of breast cancer cells, and these substances will enter the urine. They successfully identified the gene sequences of these specific RNA substances and developed corresponding test strips. A urine comparison analysis of 48 patients with confirmed breast cancer and dozens of healthy volunteers showed that the sensitivity of this breast cancer urine test paper was over 90%.
