Before use, carefully check whether the power cord is connected and robust. The wire of the linear driver of the controller and the cigarette lighter cannot be placed on the lifting link and between the upper and lower bed frames. Frequently check to avoid power failure of the wire. In the process of application, people cannot jump on the bed surface. When the back plate is raised, it is not allowed to push, and it is not allowed to move after the brake wheel is pushed. In order to prevent the damage of the guardrail, the horizontal push is also prevented. Of course, the movement on the uneven road surface is also definitely prevented. In this way, the universal wheels of the medical bed accessories will cause huge damage. When using the controller, only one function key can be pressed at a time on the control panel. It is forbidden to press multiple keys at the same time to avoid the risk of injury to the patient.

It is also very important to unplug and wind the power plug before moving the medical bed, and also raise the guardrail, so that the life safety of patients can be guaranteed even during the moving process of the medical bed.

Medical beds are often used near hospitals. Of course, medical beds also bring great convenience to our life. But when the medical bed finds some shortcomings, will you simply repair them? Now let's introduce the repair of the medical bed to you, so that you can have a better understanding of this.

After you use the medical bed, we suggest you lower it to the low position, wind the power cord controller wire, push it to a safe place, and brake its universal wheel. Avoid it from slipping.

At the same time, we also need to check the medical bed punctually, and check whether the controller line and the wires between the lines are robust and reliable, to ensure that the screws are fastened.

When you need to clean medical machinery, try to use neutral detergent for cleaning. After cleaning, use a soft dry cloth to wipe it and place it in a ventilated place. Do not use alkaline and other corrosive liquids for cleaning. Biological changes caused by surfactants and their metabolites in the body, that is, the possible side effects on the body include acute toxicity, subacute toxicity, chronic toxicity, effects on reproduction, embryotoxicity, teratogenicity, mutagenicity, carcinogenicity, sensitization, hemolysis, etc. Surfactants come into contact with different parts of the human body in different ways, and different requirements will be put forward for the above toxic and side effects.

The use of surfactants as various processing aids or synergists in the food and pharmaceutical industry increases the contact opportunities between surfactants and human digestive tract and blood system, which puts forward strict requirements for oral toxicity, hemolysis, heredity, carcinogenicity and teratogenicity of surfactants. Surfactants used in food and oral medicines such as liquid, tablet, pill, etc. must be low toxic or non-toxic substances; In case of intravenous or intramuscular injection, attention must be paid to the hemolysis of surfactant; For long-term use, it is necessary to consider the heritability, cancerous degeneration, teratogenicity and other problems that may be caused.

The steady growth trend of surfactants in the world has provided a good external environment for the development and expansion of the cosmetics industry, and the requirements for product structure, variety, performance and technology are also higher and higher. Therefore, it is necessary to systematically develop safe, mild, biodegradable and special surfactants to provide a theoretical basis for the development and application of new products. It is necessary to focus on the development of glycosidic surfactants, and a variety of polyols and alcohol surfactants can be developed; Systematically research and develop soybean phospholipid surfactants; Develop sucrose fatty acid ester series products, strengthen the research of compounding technology, and expand the application scope of existing products - surfactant is the most important component in cosmetics. In the development and application, natural raw materials should be vigorously used, and the use of ingredients that are irritating to the skin should be avoided as far as possible, so as to reduce the multiple hazards of chemical ingredients to human body, It is believed that the development of environment-friendly surfactants will greatly promote the development of functional cosmetics.

Modern fermentation industry has become the most promising industry in the 21st century due to its characteristics of low energy consumption, high yield, less pollution, low investment and high efficiency. In recent years, China's fermentation industry has shown a sustained and rapid growth momentum. The traditional fermentation industry, represented by liquor making, is rooted in urban and rural areas; The new fermentation industry represented by antibiotics, amino acids, organic acids, single cell proteins and enzyme preparations has formed a complete industrial system in China, and its scale and output account for a considerable proportion in the world.   

With the continuous development of biotechnology, the basic research of bacteria and surfactant has been deepened, and the application of surfactant in fermentation has shown great potential and superiority. Especially in the separation and purification of biomass, it has the characteristics of large processing capacity, continuous operation and low activity loss, which makes its application research in biological downstream engineering become a hot spot. According to the different functions and requirements of surfactants in fermentation production, suitable surfactants can be selected and new green and high-performance surfactants can be continuously developed. With the deepening of research and the development of science and technology, the special structure and function of surfactants will play a greater role in the fermentation industry.

In a word, there are many problems in the research of surfactants as fermentation promoters and some mechanisms of action are still unclear. As talents in the new century, we should devote ourselves to scientific development and benefit mankind.
