After the maintenance of the instrument was completed, the imported reagent was returned for testing. As expected, the background of the PLT returned to normal, so that the PLT background that was detected when using the imported cleaning solution reagent was probably the result of the coagulation. Why did the PLT background value be in the normal range before testing with normal saline or domestic reagents? The author compared the formulation of domestic cleaning solution reagents and imported cleaning solution reagents and found that the formula for the imported cleaning solution was anhydrous sodium sulfate, Sodium chloride, bactericides, surfactants, etc.; and anhydrous sodium sulfate in the domestic reagent formula, so the author analyzed that the cleaning ability of the original imported cleaning fluid is stronger than domestic reagents, in the general cleaning of the general situation, import There may be no significant difference in the cleaning ability with domestic reagents, but in some special cases, such as when blood clots are attached to pipes or electrode pads, domestic reagents cannot achieve cleaning effect; while imported reagents cannot be used at one time. Completely clear, but with a slow dissolving cleaning effect that interferes with the background detection of the PLT. Through this rarer fault handling, the author believes that imported original reagents are superior to domestic ones. Therefore, it is recommended that the user of the hemocytometer be able to use the matched imported cleaning solution. This can better clean the pipeline and extend the service life of the pipeline. The instrument has a better protection.
22-4008-02 Microscope is the most commonly used instrument in medical experiments. It is mainly used for experimental teaching and various scientific research observations. Analyze the microscopic morphology of sections such as biology, histoembryology, pathology, etc., and diagnose them in parasitology and diagnostics. All medical college students must master the operation of the microscope. Instructions. The use and maintenance of medical equipment management requires the correct use of various instruments by the management personnel, as well as the usual maintenance, complete maintenance, and repair of faults. The good management, use and maintenance of medical equipment are the preconditions and necessary conditions for the normal use of medical equipment. Medical equipment is the result of high-tech applied to clinical medicine and teaching. Its development is getting faster and faster. Maintenance personnel must not stay at the level of experience and simple testing methods. We must study technology assiduously and work hard to make progress. The speed to solve the maintenance difficulties. In order to ensure the normal opening of teaching experiments, does not affect the teaching progress, and to solve the phenomenon that the level of medical equipment development and maintenance support capabilities are incompatible, the author summarizes the following several experiences.
The use of the instrument management personnel must be skilled in mastering the functions of various instruments. The methods of use, maintenance, and inspections should be placed in a well-ventilated, ventilated, and corrosion-resistant environment. Frequent inspections should be conducted to identify problems and repair them in a timely manner. , Make the instrument in good working condition. When the teaching equipment can not meet the students' teaching experiment, according to the arrangement of the experimental class, the students will be grouped and assigned to use, so that a staff of 1 microscope, to facilitate the observation and operation of the students need to experiment, there is damage and failure, easy Find. Because the students are all new contact instruments in the operation, there may be problems with the mechanical part and the optical part in this or that way. Therefore, the maintenance personnel should promptly assist with the guidance, operation, and maintenance so that the students can successfully complete the experiment that the teacher has arranged. Lesson content.
The establishment of a complete instrument file system In the newly purchased microscope instruments, strict inspection and acceptance procedures were first implemented, and unfavorable resolute returns or exchanges of products meeting the quality requirements were encountered to avoid loss of school property. For each microscope instrument, an instrument file card is created, and the registration card for the purchase year, month, day, price, place of production, user, and custodian is filled in.
The management of the instrument cabinet is an effective method in the actual work, from the use of the original instrument cabinet to the current laboratory, and it is an effective method to avoid the time-conflict and confusion that occurs when the original instrument is used centrally. The management methods used for split-time use are not conflicting and orderly, and one instrument is used to fill in the booklet in each instrument cabinet. Each student must fill in the time of the experiment (year, month, and day) after use. The contents of the experiment and the use of the instrument (if any problem, apply for repair immediately) will not affect the normal use of the next classmate.
The instrument laboratory's management laboratory is affixed with the rules, methods, and precautions for the use of the instrument. It also requires students to maintain cleanliness and cleanliness on the stage and under the desk, and to close doors and windows and water and electricity facilities to ensure safety after use. . The overhaul of the instrument 2. 1 The overhaul of the students by the instrument consumes a large amount of instrument and the instrument loss is also large. According to these conditions, the overhaul is performed at the end of the semester, and the repair records are made. The use of the instrument is reported to the relevant leaders in a timely manner. . The instrument has a large amount of maintenance and is complex and subtle. Our school has made all kinds of small-scale practical tools to save money, and it has facilitated the maintenance work and ensured the normal use of the instrument microscope. The improvement of the microscope mirror holder has been frequently used by students for a long time, which makes the mirror holder easily fall off and cannot be fixed, which seriously affects the observation effect. Because there is no spare parts replacement, during the inspection process, the reflective lens can only be fixed after the original fixed position, or it can be fastened with a quick dry adhesive glued with 502. However, it is easy to fall off after use. The reason is that this part is poorly designed. It is riveted by a fixing bolt to pressurize it, and it is fixed by a tiny pin. Its peripheral contact surface is very thin and its fixing force is not strong. In the process of learning to repeat the operation, the mirror bracket is still loose, it is easy to fall off, can not continue to use, seriously affect the observation effect, in the practice of repair work, the microscope mirror bracket repair and improvement, the effect is very good. Improvement of the front and rear mirror holders, the specific method: the center of the holder is punched in the center of the column, the diameter of 2. 5 mm, a depth of 4 mm, and then tapping the inner diameter, with 2. 5 mm é•™Cap wire, cap with a diameter of 4.5 mm and a length of 4 mm are used to fix the entire tapped hole size. After a small screw is used to make the modification, it will not affect the appearance, and it will be durable and never appear. The phenomenon of mirror shedding has increased the efficiency of the use of microscope instruments and saved the school money.
In short, the management and maintenance of experimental instruments are an important part of teaching experiments. They must require the dedication of the experimental technicians and constantly improve their own professional quality and work level. With the continuous development of medical science, the generation and management of medical waste and its harm to society have become a social problem that cannot be ignored. To strengthen the safety management of medical waste, reduce the pollution of the hospital environment and prevent the spread of pathogenic microorganisms. In order to avoid direct damage to society and medical personnel, according to the relevant documents of the State and the Ministry of Health, the hospital implemented the entire management of the production, packaging, collection, transportation and disposal of medical waste, and achieved good results.
The production and packaging management is based on the “Catalogue of Medical Wastes†medical waste, infectious waste, pathological waste, injurious waste, pharmaceutical waste, and chemical waste. Various medical wastes produced by various departments are categorized and packaged according to requirements in strict accordance with the requirements. The leaders of the hospital specifically order yellow medical garbage bags that meet the requirements of the State Environmental Protection Agency and the Ministry of Health, and have black warning signs and hospital names printed on them. Mergers and acquisitions of special weapon boxes, closed medical waste bins, garbage trucks, and medical waste incinerators were put into use after they were accepted by the environmental protection department in our district. Disposable medical supplies, disposable medical devices, and articles contaminated with the patient's blood, body fluids, excrement, and secretions after the use of infective waste are all put into a leak-proof standard medical waste bag and reach 3/4 full. Tie tightly around the bag with a rope and label it to indicate the department, date, and category. After use, the disposable medical supplies do not need to be soaked and disinfected or disfigured. The supply room supplements the usage amount of the next day according to the amount of use of each section. This will not only save the disinfectant but also reduce the workload of nurses; the living garbage and medical waste of infectious patients and suspected patients are packed in double-layer medical garbage bags and sealed in a timely manner. Their excrement is strictly required by the “Disinfection Technical Specificationsâ€. After being disinfected, they are discharged into the sewage treatment system; the hazardous wastes such as the bacterial culture medium and specimens of the laboratory are collected and disposed in a double-layer medical waste bag after being pressure-sterilized on-site in the laboratory, and collected as infectious waste; various kinds of discarded medicine Specimens, blood, and serum are loaded into a double-layer medical garbage bag and collected as infectious waste.
The pathological tissue pathology section pathological section tissue, pathological wax pieces soaked with formaldehyde, obstetrics and gynecology, operating room placenta, human tissue, etc. stored in the refrigerator, the afternoon were packed into a medical garbage bag, sealed tightly , Labeling, indicating department, date, category.
