The biosafety cabinet is a device specially designed for intravenous drug distribution with the establishment of the dispensing center in recent years. Its main principle is to use air purification technology to complete the first physical isolation technology product. It is used to maintain the operator, laboratory environment and laboratory environment when operating infectious experimental data such as primary cultures, bacterial strains and diagnostic specimens. The experimental data are designed to prevent exposure to infectious aerosols and splashes produced during the above operations.
1. Favorable elements for liquid dispensing personnel.
1. Maintain the dispensing personnel and isolate biological contamination. Nurses should allocate antibiotics, microorganisms, chemotherapy and other pharmaceutical products for patients in the daily dispensing mode. A large number of dispensing and non-standard dispensing operations are easy to cause biological contamination to the nurses themselves. The use of biological safety cabinet greatly reduces the damage to human body caused by this pollution, and effectively avoids the threat of physical health caused by adverse factors in the traditional operation process.
2. Intelligent control, reduce the objective impact, enter the period of computerized intelligent control, the intelligent control system of safety cabinet is used to monitor the operation value of biological safety cabinet, find any faults and wrong operation in time, notify users with sound and light alarm to take measures, and automatically take corresponding chain safety measures.
3. Distribution field of vision is clear, problems are found in time, and the lighting lamp meets the needs of dispensing in terms of interval and brightness, so that dispensing personnel can more clearly and meticulously inspect the status of dispensing liquid, which is more conducive to timely discovery of the characteristics and quality of drugs in the liquid, impurities, precipitation and other conditions, and plays a great role in ensuring the safety of patients'transfusion.
2. Favorable factors for the quality of liquid distribution.
1. Detailed classification to meet all kinds of requests, biological safety cabinet is divided into 1, 2 and 3 levels, which can meet the application requirements of pathogenic microorganisms in different operational risk groups. It can be widely used in clinical medicine, biopharmaceuticals, gene recombination, animal and plant experiments, inspection and quarantine, etc.
2. Improving the environment and quality of intravenous medication can not guarantee the quality of intravenous medication because of the limitations of traditional nursing work. With the establishment of liquid distribution center and the application of biological safety cabinet, the above problems have been effectively dealt with and the quality of liquid distribution has been greatly improved.
3. Good operation mechanism to ensure aseptic dispensing, biological safety cabinet in operation, in order to ensure the sterility of dispensing, set up a number of functions. The cabinet is equipped with ultraviolet disinfection lamp tube at 100 cm interval operation platform, so as to stop thorough disinfection of the liquid distribution space at its most effective interval and time, and to invent a sterile environment. At the same time, the counter of safety cabinet has a high-speed suction trough to prevent toxic aerosols from leaking to safety cabinet. Safety cabinet adopts "barrier-free return air cleaning equipment" to avoid the influence of external air on the working chamber, so as to effectively maintain the safety of the actors and the distribution of drugs.
4. Regular detection function, timely repair of defects, configuring biological safety cabinet is not only to ensure its initial performance and installation integrity, but also to stop the leakage inspection and airflow velocity inspection of biological safety cabinet every six months in the subsequent operation process. It can also be done by the infection control room regularly to detect sedimentation bacteria, so that it is convenient to pay attention to the working status of biological safety cabinet at any time.
