During the growth process, fruits and vegetables do not know how many pesticides have gone through pesticides and other harmful substances. Seriously threatened people's health. Therefore, our demand for pesticide residues is increasingly urgent. How to quickly and easily determine the pesticide residue content in agricultural products such as fruits and vegetables has become the basic requirement of the industry.The pesticide residue detector is an agricultural residue testing instrument specially applied to vegetable agricultural products. The application in the rapid technology of agricultural residues has given full play to the fast inspection role of the instrument, expanded the scope of the detection of agricultural disability, and shortened the testing cycle to reduce the testing The cost, provides effective and accurate agricultural residue testing services for agricultural product trial production.The pesticide residue detector can determine the amount of residues of organic phosphorus and amino -based pesticides in agricultural products. The pesticide residue testing device is inhibited by enzyme inhibitory. Under certain conditions, organic phosphorus and aminic acid pesticides have inhibitory effects on the normal function of choline, and its inhibitory rate is positively correlated with the concentration of pesticides. Therefore, the amount of residues of organic phosphorus and amino -amino -based pesticides can be measured.In agricultural production, organic phosphorus and amino -based pesticides will be seriously harmful to the human body. Many places have prohibited the use of such drugs. However, many pesticides on the market contain organic phosphorus and amino -based pesticides. These drugs will be applied to agricultural planting, agricultural products will transfer to supermarkets and wholesale markets, and once again on people's tables.Through fast -checking technologies such as pesticide residues detectors, the detection process of agricultural residues is simplified, and the test efficiency has been significantly improved. Not only professional testing institutions can carry out agricultural disability testing, that is, ordinary production and sales venues such as production bases, farmers' markets, supermarkets, etc. Fast detection can also be carried out with the help of pesticide residues to effectively ensure the quality and safety of agricultural products and create healthy agricultural products without pesticide residues.

　　Author：MeCan Medical–ultrasound machine manufacturersWhether 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.

　　Author：MeCan Medical–ultrasound machine manufacturersWhat is Doppler color Doppler ultrasound? Doppler color Doppler ultrasound is said to be ultrasonic inspection, referred to as D -type ultrasound diagnostic instrument. This type of diagnostic device is a medical device that uses the principle of Doppler effects to detect the instrument and blood flow of the movement. Doppler ultrasound diagnostic instrument has the advantages of two -dimensional ultrasound structure images, but also provides rich information about blood flow dynamics.Doppler ultrasound diagnostic instrument has many application value in clinical practice, such as::1. The benign and malignant diagnosis of abdominal and superficial organs.2. The scope of the scope of superficial organs such as obstetrics, gynecology, and thyroid gland improves the early diagnosis of micro -lesions, increasing the unclear boundary, and deep difficulty detecting the detection rate of lesions.3. System screening that can be used for fetus has greatly increased the ultrasound detection rate of fetal malformations.4. It can also be used for disease testing of the valve valve of the heart.However, color Doppler ultrasound can be checked for substantive organs. Some internal organs are not available, such as stomach and intestines. Therefore, people with gastrointestinal disease should not try to check the condition through the Doppler ultrasonic diagnostic instrument.Precautions for Doppler ultrasound diagnostic meters:1. Doppler ultrasonic diagnostic device checks the liver, spleen, bile, and pancreas. Do not eat too greasy one night before the examination. Poor gallbladder is full, affecting the diagnosis of gallbladder disease, eating gastrointestinal gas in the gastrointestinal gastrointestinal, affecting the liver and pancreas. Diagnosis of disease.2. Doppler ultrasonic diagnostic device checks the kidney, ureter, bladder, prostate, and uterine attachments that need to be urinating. It is better to hold it until there is a strong urination. The structure display is clear.The above is the relevant introduction of Doppler color Doppler ultrasound. I hope that the above content will be helpful to you. If you want to know, or purchase the Doppler ultrasonic diagnostic instrument, please consult 400-6656-888.

　　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.

　　Author：MeCan Medical–ultrasound machine manufacturersThe hospital's modernization is inseparable from various advanced medical equipment, and the use of advanced medical equipment helps doctors to better judge the patient's condition. However, for medical equipment, high precision, high -priced, complex maintenance, shorter update cycle, the installation and use environment of equipment also requires relatively high requirements.In some large hospitals, medical equipment, as a fixed assets of the hospital, occupies more than half of the total asset value, and it is undoubtedly of great significance for the management of medical equipment. Preventive maintenance of medical equipment is the basis for managing medical equipment, extending the service life of medical equipment, and improving the accuracy of medical equipment diagnosis of diseases.Therefore, it is of great significance to improve the attention of medical equipment maintenance and establish and improve the management system of medical equipment in the hospital.Preventive maintenance concept: Preventive maintenance means that within a certain cycle, the device can systematically check, detect, maintain, and replace the wear parts, so that the equipment can work normally. Through preventive maintenance, the fault rate of the equipment is reduced, the maintenance time of maintenance is reduced, and the work of various tasks will be carried out smoothly.The necessity of implementation of anti -maintenance: The maintenance of medical equipment after use is essential. The implementation of preventive maintenance is to regularly maintain medical equipment. By maintaining the equipment to familiarize the structure of the device, understand the current equipment. During the maintenance process, the maintenance personnel accurately record the important conditions such as the equipment indicator and the work parameters, and then can make a rapid judgment of the fault position after recording the contrast after the medical equipment fails.Through preventive maintenance, the situation of the easy -to -wear parts of medical equipment, timely purchase parts and replace it, thereby reducing the incidence of medical equipment failure, avoiding normal examination and treatment of patients due to medical equipment failure or medical accidents. Implementation of preventive maintenance will allow medical equipment to run for a long time in a healthy state, and the service life will be extended.

　　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.

　　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.

　　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.
