What Is Antigen Detection, Can the Antigen Detection Replace the Nucleic Acid Detection?

  Author:MeCan Medical–ultrasound machine manufacturers

Whether the virus invades the human body, there are currently three methods to detect: nucleic acid detection, antigen detection, and antibody detection. Both the first two are the method of directly detecting the virus. Compared with nucleic acid detection, the antigen detection speed can be faster and more convenient to operate, but the accuracy is low, which is generally used in early infection. After the epidemic, while the recognition of nucleic acid detection as the "gold standard" as a new coronal virus detection, antigen testing has also been promoted, which is an effective supplement.

Which people are mainly applicable to antigen detection?

1. First, go to the grass -roots medical and health institutions for treatment, accompanied by symptoms such as respiratory tract, fever and other symptoms within 5 days;

2. The second is to quarantine observers, including home isolation observations, secrets and sub -dense personnel, as well as personnel in the entry isolation observation, sealing control areas, and management control areas.

3. Third, there are community residents with antigen self -detection needs.

Can antigen detection instead of nucleic acid detection?

The antigen detection speed is faster and the operation is more convenient, but the accuracy is relatively low. Yang Guoliang clearly stated that nucleic acid testing is still the confirmation basis for new coronary virus infections. The antigen test as a supplementary method can be used for screening of specific groups, which is conducive to improving the ability to "early discovery", but it is not used as a diagnosis basis for the new coronary virus infection.

According to the "New Crown Virus Antigen Detection Application Scheme (Trial)", if a primary medical and health institution has nucleic acid detection capacity, nucleic acid testing shall be selected; if there is no nucleic acid detection capacity, antigen detection may be performed. Observation personnel and community residents conduct antigen testing. They should carefully read the instructions and standardize operations. Once the antigen detection is positive, report it to the relevant departments immediately; when needed, the nucleic acid test is confirmed.

For anti -original detection negative personnel, grass -roots medical and health institutions shall give symptomatic treatment and instructed their home to observe. From the day of the clinic, we will conduct antigen detection once a day for 5 consecutive days to avoid social activities, correctly wear masks, and wash their hands and ventilation. The antigen result has always been negative and until the symptoms disappear, but other intervention measures are not taken. Once the antigen result is positive, the positive personnel need to report to the community (village and town) in the community (village) immediately. The community (village) contacts the emergency center according to the transfer of the personnel transfer work of the new crown pneumonia. The positive personnel use the sampling swab, sampling tube, detection card, etc. into a sealed bag and transfer to the medical institution as a medical waste disposal.

Why Does Medical Ventilator Be Used in Medical Institutions?
  Author:MeCan Medical–ultrasound machine manufacturersWith the progress of modern medicine, more and more medical ventilator is applied to emergency rescue, anesthesia, postoperative recovery, respiratory treatment and respiratory maintenance, and possess important positions in medical equipment. The mechanical ventilation of medical ventilator includes non -invasive and ventilated parts. Non -invasive positive pressure ventilation refers to the positive pressure mechanical ventilation method that does not need to establish an artificial airway. The clinical application of mouth and nose mask or nasal mask is used for positive pressure ventilation. Positive -pressure mechanical ventilation method performed by the tracheal intubation and bronchial cutting).There is a ventilator that needs to be used after "tracheal intubation or bronchial cutting", that is, professional medical personnel should be inserted by the patient's mouth or nasal trachea or cut the trachea from the neck. Receive the ventilator to provide ventilation support for patients. It is mainly aimed at patients with unconsciousness, free breathing, or unable to withstand non -invasive ventilator. The advantage of creating ventilator is that it can connect high pressure, high flow, and high concentration of oxygen to meet the needs of patients with severe illnesses and can absorb phlegm to keep the airway unobstructed. Patients with severe illnesses need to be monitored throughout the process, so they are usually only suitable for use in professional medical institutions.Medical ventilator is mainly used in hospitals, which are suitable for various conditions and various conditions. The purpose of its treatment is: 1. Maintain the appropriate amount of ventilation so that the amount of alveolar ventilation meets the body's needs. Improve the gas exchange function and maintain effective gas exchange. 2. Reduce the work of respiratory muscles. 3. Inhalation treatment of lung in internal lung. 4. Preventive mechanical ventilation, used for respiratory failure treatment after thoracic or sepsis, shock, and severe trauma.So why do medical ventilator be used in medical institutions?In clinical, medical breathing opportunities are based on the patient's condition, vital signs, and blood oxygen saturation, and adjust the support pressure and oxygen supply at any time through lung dynamic parameters. Synchronize with patients. This complex system also has high requirements for stability. Whether it is the pressure driving system, the patient's circuit, the filter or the valve, any parts of the component failure, the ventilator may fail, and endanger patient life. Use.

Brief Analysis of the Current Development Status and Trend of Chinese Medical Device
  Author:MeCan Medical–ultrasound machine manufacturersAt present, the epidemic is still spreading globally, and international trade and economic growth have stalled. Although the exports of Chinese medical equipment remain stable as a whole, they need to be alert to relevant risks and challenges. The relevant person in charge of the Medical Institution Department of the Medical Insurance Chamber of Commerce pointed out that in the short term, due to the needs of epidemic prevention and immunity, the global market has increased its dependence on the supply chain of Chinese medical device.In the long run, the epidemic has become a catalyst for reshaping the global industrial structure. With the introduction of policies in various countries, international competition will intensify, and the competition between Chinese medical devices in the global market will be more intense.In terms of market risks, the global economic recovery will lower the ability of the international market to procure ordinary medical supplies. The surge in demand for epidemic prevention materials, coupled with the decline in the efficiency of the port work, has caused serious lag in the circulation of containers, bringing a sharp increase in international logistics costs, especially shipping. The rise in raw materials and labor costs, and the strengthening of the supervision of merchants by cross -border e -commerce platforms will further squeeze the export profits of the enterprise.In addition, due to international travel restrictions, it is difficult for engineers and sales staff to conduct promotion activities in overseas markets and after -sales service for some large -scale equipment exported equipment, and it is not conducive to market sales.Overseas market expansion also needs to focus on the impact of changes in international market regulations. For example, the European Union has implemented new medical device regulations (MDR) and in vitro diagnostic medical device regulations (IVDR), pay more attention to the clinical performance of the product, strengthen the traceability of medical device products, and pay attention to improving the transparency of patients.These will improve the management and restrictions on medical device products entering the European market accordingly, and put forward higher requirements for the industry's employees, which will bring about increased costs to Chinese export companies, extending certification cycle, and increasing compliance risks, etc. challenge.
Let's Briefly Introduce the Application of Enzymes Immune Detector in Pesticides and Food
Let's Briefly Introduce the Application of Enzymes Immune Detector in Pesticides and Food
  Author:MeCan Medical–ultrasound machine manufacturersThe enzyme missionary instrument is commonly known as the enzyme -linked immunohistic detection instrument. It can be simply divided into two categories: semi -automatic and fully automatic, but its working principles are basically the same. The core of its core is a color meter, that is, the color method is used to analyze the content of the antigen or antibody. Clinical examination, biology research, agricultural science, food and environmental science. Let me introduce the application of enzyme -linked immune detector in pesticides and food.1. Fast diagnosis of animal epidemic.The enzyme -linked immune analyzer adopts the enzyme -linked immune adsorption measurement method and the corresponding reagent with a qualitative or quantitative animal disease diagnosis. Such as: pork blue ear virus, swine fever virus, pig pseudo -rabies virus, pig pseudo -rabies virus GE protein, pig ring virus, pork type encephalitis virus, pig mouth hoof disease 3ABC protein, pig mouth hoof disease virus IgG, pork fine virus, chicken chicken, chicken Bird flu, blue tongue disease, white spot syndrome, cattle infectious pleural pneumonia, cattle plague, cotton acne, and sheep acne detection.Second, pesticide residues.Organic phosphorus pesticides are commonly used in agricultural production in my country. Common types include methylmine, dichlorvos, oxygen fruit, phosphorus, and enemies. Most of them are highly toxic pesticides. By reducing the activity of cholthyne enzymes in the body, delayed neurotoxicity is caused, thereby achieving the purpose of eliminating pests. The enzyme -linked immune detector can be used to detect the methamidine content contained in fruits and vegetables.Third, food safetyThe enzyme -linked immune analysis method uses the special nature of the antibody and the corresponding antigen to detect the antibody contained in the food based on this. The immune enzyme method is to use specific enzymes as detection tags and reaction catalysts. The use of this method can be used to effectively avoid using radioactive elements during the detection process, or to conduct orientation and quantitative analysis of the detected objects. , Chemical residue, edible oil testing, water and wine beverage analysis, condiments, edible pigment, etc.At present, more automatic enzyme -linked immune detectors can be used for qualitative detection and quantitative detection. The detection only takes a few hours. It not only reduces the labor intensity of laboratory personnel, but also greatly improves the accuracy and repeatability of the determination. This is conducive to the further commercialization of ELISA technology in detection and analysis.
How Does the Magnetic Pearl Nucleic Acid Extraction Extract Nucleic Acid and Where Is the Advantage?
How Does the Magnetic Pearl Nucleic Acid Extraction Extract Nucleic Acid and Where Is the Advantage?
  Author:MeCan Medical–ultrasound machine manufacturersAs one of the current effective epidemic prevention and control methods, nucleic acid extraction and testing are no stranger to everyone. Prior to this, the method of extracting the traditional nucleic acid was chemical cracking and cylindrical method. However, with the rapid development of gene diagnosis, genetically modified food detection, and personalized medical care, traditional nucleic acid extraction technology can no longer meet the needs of today's biotechnology. As a result, magnetic pearl nucleic acid extraction came into being.No. A commercialized reagent that used the magnetic bead method to extract DNA and successfully applied for patents in the United States appeared in 1998. The magnetic bead method first absorbs the free nucleic acid molecule to the surface of the magnetic particles by cracking the cells, while the protein and polysaccharides are left in the solution. Under the influence of the magnetic field, the magnetic particles are separated from the liquid to discard the liquid to eliminate the liquid Later, the purified nucleic acid molecules were obtained after being eluted.The magnetic bead method uses the principle of combining and dissipating the magnetic acid activity group with a magnetic granular activity group under certain conditions to avoid the loss of nucleic acid during the extraction process as much as possible, and it can also remove the interference substances in the specimen (such as hemoglobin The effects of bilirubin and lipid blood), obtain high -quality nucleic acid templates. With the development of magnetic bead method extraction technology, DNA extraction has really begun to achieve standardization, rapidness and automation.The kits based on the magnetic acid extractor of the Magnetic Pearl Method are also widely used. Nucleic acid extraction kit does not require any organic solvent and no need to repeat centrifugation. At present, it can extract high -quality DNA and RNA from full blood, serum, plasma, saliva, urine, feces, cerebrospinal fluid, tissue and cells, and shorter time. The recovery rate is higher. And it can be automated and uninvited through mechanical equipment.In addition, the principle of magnetic pearl method is safe and non -toxic, and does not use toxic reagents such as benzene and chloroform in traditional methods. Mainstream nucleic acid extraction methods at home and abroad.
