Any Good Brands for Security Safe?

This might be an odd question, but I often take a sandwich or fruit to eat while waiting for the airplane. This means that my food goes through the security x-ray machine. I don't understand much about radioactivity, so I was wondering: Is it safe to eat that food right after going through the security machine? or suffer harmful mutations that can affect ones health? Can it keep some latent/cumulative radioactive effect? Bananas, by nature have a very low level of radioactivity. Does it get increased, for example? Can I safely eat the food that goes through the x-ray machine after the security check? There is XRays are the second kind, ionizing radiation, meaning they may alter some molecules (i.e. the arrangement of atoms), but will not affect the atoms themselves(so no radioactivity is created). The altering of molecules may also happen to the DNA molecule, which is why XRays are kept to a minimum. So the apple sent through the machine might get a mutation, but the chance of that being a problem to the apple are remote, and the mutated apple being a problem to you is virtually nonexistent. Sending old school films through an old school XRay might be a problem for the film (film is coated with molecules that are easily altered, because detecting (visible)radiation is it's job, and old XRays used higher power sources).Your association of XRay machines with radioactivity might come from the hazard sign above, that is sometimes quite prominently displayed on Xray machines. It simply warns of ionizing radiation, which can, as stated, damage your DNA, thereby giving you cancer, etc, depending on strength. It's popular meaning of "Danger! Radioactivity" came about because radioactive materials emit ionizing radiation (that's actually why it's called radioactive, the ionizing radiation messes with radio-equipment). So Radioactive materials emit ionizing radiation, but ionizing radiation does not produce radioactivity. OTHER ANSWER: x-rays are a form of light, just a frequency that your eye cannot see.exposing food to xrays, in any amount, will not make the food radioactive, just like shining a very bright light on your food will not make it shine once you turn the light off.Exposing food to fatal doses of EM radiation (like xrays) is how the US Department of Defense prepares its field rations. This technique has been extensively studied since the 60's by academia and the military alike, and no adverse effects have been found

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.

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.

　　Author：MeCan Medical–ultrasound machine manufacturersThe nucleic acid extract instrument is a supporting nucleic acid extract reagent from the motion to complete the sample nucleic acid extraction work. In the detection of the new crown, nucleic acid extraction is a very important step. At present, the extraction principle of nucleic acid extract instruments on the market is mainly divided into two types: magnetic bead method and membrane adsorption method, of which magnetic bead method occupies the mainstream market. So, what is the extraction step of the magnetic pearl nucleic acid extract instrument?Step 1: Add samples to the cracking solution.Step 2: In the cracking solution, the rupture cells release the nucleic acid to the cracking solution to transfer the magnetic beads to the cracking solution step 3: Fully mix the nucleic acid to adsorb the specific package on the surface of the magnetic beads.Step 4: Repeat the surface of the magnetic beads to remove impurities such as the unnecessary nucleic acid, protein or salt that are not needed.Step 5: Move the magnetic beads into the eluing solution and mix it fully. The nucleic acid is falling off from the surface of the magnetic bead and dissolved into the elution buffer.The magnetic pearl nucleic acid extract instrument is matched with different types of magnetic pearl nucleic acid extract reagents, and multiple samples are operated at the same time, which automatically separate the extraction and purification DNA/RNA from multiple samples such as blood, cells, tissues, viruses. The instrument uses a special magnetic stick adsorption, transfer, and releases magnetic beads to achieve the transfer of sample/magnetic bead/nucleic acid, avoiding liquid treatment, and increasing the degree of automation.Nucleic acid detection, as an important means of screening of new crown virus screening, is expected to maintain a high position for a period of time at home and abroad. The corresponding nucleic acid extract will be very strong in a considerable period of time. The operation is automated, fast, and simple, which provides a strong guarantee for the detection of new crown nucleic acid.

It is widely used in various fields such as disease control centers, clinical disease diagnosis, blood transfusion safety, forensic identification, environmental microbial testing, food safety testing, animal husbandry and molecular biology research. In fact, with the normalized management of the epidemic, the nucleic acid extract instrument, as one of the commonly used equipment tested by various hospitals, has a higher frequency and the number of purchases has continued to rise. In fact, although everyone is familiar with the term of the nucleic acid extract instrument now, but it is very familiar with the term, but it is very familiar with the term of the nucleic acid extract instrument, but it is very familiar with the term, but it is very familiar with the term. I do nt know how to work and test the method of working principles. Let s take a closer look at the editor of Prank Medical Equipment.There are many classifications of nucleic acid extract instruments. In fact, the most commonly used is magnetic bead method. How does this method work? Magnetic pearl nucleic acid extract instrument is generally divided into two types: suction method and magnetic stick method. The specific operation process is as follows:First, suction method. The extraction of nucleic acids is achieved by fixed magnetic beads and metastasis liquids. Generally, the transfer of the robotic arm is generally controlled by the operating system.1. Crack. Add a cracking solution to the sample to achieve mixing and adequate reactions of the reaction solution through mechanical exercise and heating, cell cracks, and release nucleic acids.2. Adsorption. Add magnetic beads to the sample cracking solution and mix it in full. Use magnetic beads to adsorb nucleic acid under high salt and low pH value. Under the action of magnetic fields, the magnetic beads are separated from the solution. Mo the liquid out of the waste liquid tank and abandon the head.3. Washing. Remove the external magnetic field, add the new suction head to add the washing buffer, mix it fully, remove the impurities, and remove the liquid out of the magnetic field.4. Requesting. Withdrawing the magnetic field and adding the new suction head to add the elution buffer, fully mixed, the combined nucleic acid is separated from the magnetic bead, so as to obtain a purified nucleic acid.Second, magnetic stick method. By fixed liquids, the magnetic acid is separated to achieve the separation of nucleic acids. The principle and process are the same as the pumping method. The difference is the method of separation of magnetic beads and liquids. The magnetic stick method is to separate the magnetic beads from the waste liquid through the adsorption of the magnetic rod to the next step to achieve the extraction of nucleic acid.In fact, the characteristics of this magnetic pearl nucleic acid extract instrument is that it can achieve automation, high -throughput operations, safe and reliable operations, high efficiency, and pollution -free. Therefore, it is recognized by many buyers. When choosing a nucleic acid extraction instrument equipment, no matter which type of device is selected, you must have a basic understanding of it. You cannot judge the quality of the product from the price alone. For more product details, you can consult: 400-6656 -888.

Speaking of magnetic beads, then we must first understand what is magnetic beads? Magnetic beads are formed by a certain tissue package being absorbed by the core of the four -iron oxidation triple iron. It can be adsorbed by the magnet. At the same time, there are magical little beads that can adsorb (binding) nucleic acids that can be adsorbed by the surface bread. It can achieve automation and high -throughput of nucleic acid extraction.Magnetic beads are generally divided into three layers of structure: inner layers: the kernels for supporting structures, such as polystyrene. The middle layer: the magnetic layer, the role is to adsorb the magnets on the magnetic frame, which is to separate the nucleic acid and the reactive solution. The material is usually Fe3O4. Outer layer: modified layer, generally a negative group.The weight of the magnetic pearl nucleic acid extract instrument is the adsorption ability of magnetic beads and nucleic acids, which directly affects the output of the extraction nucleic acid.

The two are slightly different in patterns, parameters, and algorithms. The models are also different.Our common home ventilator is mainly divided into these modes, namely: CPAP, APAP, Auto BPAP and other modes. It is mainly for snoring patients. Which mode of home respiratory machine is good? The editor of the Proven Medical Equipment manufacturer will introduce it in detail.1. Single horizontal ventilator -CPAPSingle -horizontal ventilator CPAP is a single horizontal ventilator. This mode is the basis of the ventilator. The advantage is that the principle is simple, the technology is mature, and there is no special differentiation between the brands. The price is also cheaper, suitable for buying in patients with snoring.2. Dual -level ventilator -BPAPThe BPAP of the dual -horizontal ventilator will provide a higher inhalation pressure and a lower exhalation pressure. When the patient is inhaled, the pressure is large. When the patient exhales, the pressure is less. It can help patients to complete their breath smoothly, and comfort can be described as greatly improved.We must have a certain consciousness of the danger of snoring. If we are serious, in early intervention, under the guidance of a doctor, use household ventilator to assist, at the same time improve our own daily life, good eating habits, exercise more, improve ourselves Snoring.
