The 22nd International Medical Instruments and Equipment Exhibition closed at the Beijing International Convention Center. More than 500 medical device manufacturers from more than 20 countries and regions showcase the latest products, and some of them can be used for home medical care and health care. The reporter saw new products of medical instruments from internationally renowned companies such as Philips, Johnson & Johnson, Siemens and GE. Small home blood glucose meters, massagers, and home-use semi-automated external defibrillators are refreshing. The field personnel also demonstrated the use of vacuum splints, including the use of the head splint, upper and lower limbs, and even the wrist and ankle splint, so that the audience had a certain understanding of family first aid. In addition, some of the latest international telemedicine services can use Internet technology to monitor cardiac pacemakers, implantable defibrillators and other heart disease-related symptoms.

According to the organizer, as people's self-care awareness and the aging process continue to accelerate, the demand for medical services will increase, and the demand for medical devices for disease diagnosis and treatment will increase in the same period. Domestic companies not only maintain a huge share in the low-end market, but also accelerate the penetration of high-end markets. Various new home appliances will appear in the market to meet people's needs. Meditech Medical Network
Insect pheromones are compounds used by insects to represent various information such as aggregation, foraging, mating, and alerting. They are the chemical molecular language of insect communication. At present, the basic control measures for pests in agricultural production mainly rely on chemical pesticides, but the long-term uncontrolled use of chemical pesticides has brought many side effects. The first is the emergence of pest resistance, which causes the use of drugs and drug concentrations to increase, the cost increases year by year, and the prevention and control of increasingly difficult; the second is to disrupt the ecological balance, while controlling a large number of natural enemies were killed, causing the pupae of secondary pests; Third, it pollutes the environment. A large amount of pesticides remain in crops, soils, rivers, lakes, and seas, and they are enriched in the human body through the form of food chain, causing another harm to humanity. Therefore, relevant research departments in many countries are currently working hard to explore and study new approaches and technologies for pest control. These studies include: the development of new, efficient, environmentally friendly, low-toxic, low-residue chemical pesticides; natural enemy insects and microorganisms The use of pesticides; insect sterilization technology and the application of insect hormones; among them, the research on the use of insect hormones, especially insect sex pheromones for pest control, is receiving increasing attention and attention.
Research on insect pheromone has been developing rapidly. Since the first insect pheromone Bombykol, has been isolated and identified, more than 2,000 insect pheromones and their analogs have been identified and synthesized worldwide, of which more than 100 insect pheromone To achieve commercial production, the production and research of Lepidoptera sex pheromones is the most extensive and comprehensive.
