There have been data showing that since the economic crisis in 2008, almost all medical device companies have increased their R&D expenditures in fiscal 2011 in the face of a sluggish economy. Regardless of the global economic situation, investing in the future is crucial, and medical devices have always been a hot area. Recently, foreign medical websites have reported some new medical device products that can play an important role in the prevention and treatment of diseases.
United States: an instrument for easy assessment of Alzheimer's disease
Alzheimer's disease (AD, commonly known as Alzheimer's disease) has become a serious social public health problem in the face of increasing aging. Its high incidence and high disability rate have become major diseases affecting human health. The disease is a serious hazard to human health, but people have not yet found an effective response.
The reality is that the current accurate diagnosis and diagnosis of Alzheimer's disease mainly depends on experienced neurologists, and the ability of general physicians to diagnose and diagnose is generally insufficient. This is because there are many similarities between early Alzheimer's disease and other cognitive impairments and mood 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 in sequence on the display of the instrument. The old man identifies the content on the pattern, and the instrument can analyze and score according to the reaction of the elderly to help determine the disease status of Alzheimer's disease.
Australia: Skin film that monitors harmful gases
The horrible haze has caused people to pay attention to air quality, and the indoor air environment after decoration is also closely related to human health. Researchers at the Royal Melbourne Institute of Technology have developed a new type of flexible, fully transparent film-coating agent that not only monitors the concentration of hydrogen and nitrogen dioxide in the air, but also monitors the intensity of UV radiation for a variety of uses.
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.
Japan: New equipment for powerful and fast gravel
Stone disease is a common and frequently-occurring disease. In recent years, with the improvement of people's living standards, the incidence of stone disease has increased year by year, 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 - SPSESYSTEM. 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.
United States: "TV Helmet" helps overcome fear of heights
In daily life, many people are “fear of heights†– they are afraid of climbing, climbing upstairs and overlooking the scenes under their feet, and even more afraid of flying. Suffering from high fear symptoms will have a certain impact on your 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 present 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 make the new sitting in the ground training room The pilot "sees" the virtual runway and the buildings near the airport.
Germany: High sensitivity of test strips for detecting breast cancer with a small amount of urine
Breast cancer has become the most threatening disease for women, and the incidence rate is about 7-10% of all kinds of malignant tumors. However, the symptoms of early or even mid-stage breast cancer are not obvious. 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%.
It is very important to find the signs of disease 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.
With the continuous development of China's medical industry and the upgrading of medical service demand, the trend of hospital informationization has led to an increase in demand for medical devices. It is necessary to thoroughly improve the competitiveness of China's medical device industry in the international market, break the current industry structure and the monopoly of international giants, increase investment in research and development, vigorously improve the scientific and technological content of products, and actively develop imported alternative products, which will become the inevitable result of the domestic medical device industry. select.
