Recently, foreign medical equipment new technology, new equipment highlights
Recently, the US Medical Device Network released some recent advances in the field of medical devices. Among them, it is particularly worth noting that foreign researchers have invented external charging and similar principles to permanent-moving watches for the charging of implantable medical devices. Human body kinetic energy conversion charging device. These technologies and equipment are quite innovative and reflect the demand for medical devices in the foreign clinical community.
New Zealand invention implanted device in vitro charging technology
Many patients around the world have installed small implantable electronic medical devices such as pacemakers or electronic insulin pumps to reduce accidents, improve quality of life and extend life. However, the problem that cannot be ignored is that although implantable cardiac pacemakers currently use long-life batteries (usually available for 5 to 7 years), once the battery power is exhausted, the patient must perform surgery to replace the battery again; For diabetic patients who install an electronic insulin pump, because the electronic pump consumes a large amount of electricity, it is usually necessary to expose the battery lead of the device through the skin to be charged, so that it can easily cause a fatal disease such as bacterial infection or sepsis.
In response to the deficiencies of these implantable devices, researchers at a radio technology institute in Auckland, New Zealand, invented a new wireless charging technology. The principle is that a micro-coil is built into the implantable device, and the magnetic field of the built-in coil is changed outside the body to generate a current to charge the battery.
British invention of human kinetic energy conversion charging device Researchers at the Zorlink semiconduct Electronic Medical Device Research Institute in the UK have proposed a bold scientific idea: whether the energy generated by the movement of the body's own organs (such as heart beats, joint activities, etc.) can be used for implantation. Battery charging for medical devices? This bold scientific vision was funded by a £500,000 international consortium in the UK. Recently, the institute has developed a new electronic device that intelligently collects the energy generated by human activities and converts it into electrical energy, thereby enabling the charging of implantable medical devices and the use of implantable medical devices indefinitely. Go on. This new technology is expected to be used in cardiac pacemakers, electronic nerve impulse stimulators to prevent seizures, heart monitors, urinary incontinence control solenoid valves, drug controlled release applicators, and electronic ear and kidney implant pumps. .
The United States launched a new cervical cancer DNA tester Cervical cancer has become a major cancer that seriously threatens women's health. According to reports, in recent years, the United States has added 6.2 million cervical cancer patients each year. Studies have shown that if cervical cancer is detected early, the mortality rate of patients can be reduced by about 90%. The traditional examination method for cervical cancer is “Bapanicolau testâ€, that is, taking women's vaginal mucus to check epithelial cell shedding, but this method has a high rate of missed detection. Recently, Digene Bioengineering Co., Ltd. of the United States invented a special analyzer for cervical cancer DNA.
According to research and development personnel, cervical cancer is mainly caused by human papillomavirus (HPV) infection. There are dozens of variants of HPV, among which the most likely to induce cervical cancer are strains 13, 13, and 52. Using a dedicated DNA analyzer developed by Digene Bioengineering Co., Ltd. for the above highly carcinogenic HPV strain, doctors can obtain a small amount of vaginal secretion examination to know whether the subject has been infected with the highly carcinogenic HPV strain and cancer.
The CEO of Digene said that if the cervical cancer DNA analyzer can be used in combination with the conventional Bapanicolau test, it is expected to greatly improve the detection rate of early cervical cancer, thus saving more patients' lives.
US production of hysteroscope disinfection device Cycyc medical device company under the Marlboro Group of the United States spent 60 million US dollars to purchase the patented technology of hysteroscope disinfection device invented by Adeza Medical Device Research Institute of California and put it into production a few days ago.
Every year, hundreds of thousands of women in the United States develop bacterial infections during intrauterine surgery (such as endometrial partial resection and tubal ligation), so complete and thorough postoperative disinfection is critical for patients.
According to reports, when using the sterilizer in surgery, it is necessary to add a highly effective and safe disinfectant to the inside of the hysteroscope made of optical fiber. After the intrauterine operation is completed, the doctor can immediately disinfect with a hysteroscope. The instrument is sterilized.
The CEO of Cytyc Medical Devices is optimistic that the annual sales of this hysteroscope sterilizer is expected to reach $215 million. Because at least 700,000 women of childbearing age in the United States receive tubal ligation every year, and hundreds of thousands of women undergo partial endometrial surgery, the market prospects for hysteroscope disinfection are very good, and the US market is still No competition for similar products. ——Shanghai Medical Device Industry Association
