Laboratory chemical reagent containers belong to what medical waste

With the development of new equipment and technology for testing, testing laboratories have gradually realized the automation of testing equipment, reagents, commercialization, laboratory consumables disposable, and therefore the Department of Laboratory Medical Waste has gradually increased the test waste, test waste mainly from blood, urine, stool, sputum and other specimens, plastics, glass, and other disposable items and experimental process of chemical reagents and instrumentation discharged in the waste liquid. Most of the waste liquid and (or) waste discarded by hospital laboratories contain viruses, bacteria and toxic and harmful components, and even contain highly toxic substances, carcinogens and so on. In order to public **** safety and medical workers own safety, the author of the hospital laboratory waste liquid and waste management, treatment methods are introduced as follows.1 disposable medical supplies in order to ensure that the use of disposable medical supplies do not flow into the community caused by medical infections, it must be disinfected first disfigurement and harmless treatment by the operator will be used after the use of a disposable syringe needle and syringe separation, the needle plug removed The operator will separate the used disposable syringe needles from the syringes, remove the plugs and soak the needles in a rigid container with a lid containing 84 disinfectant solution prepared according to the requirements for 30min, and then the hygienist of each department will be responsible for all the disfiguring and incineration treatment. And do a good job of processing records and the name of the disfigured person registered at the end of each month to report to the Hospital Infection Management Office, by the Hospital Infection Management Office of the hospital staff to summarize the number of disfigured recycling, and the number of departments reported to check and supervise the requirements of the use of disposable syringes after the number of matching the number of retrieved. Disposable blood collection needles are put into the special sharps "safety box" after use, and incinerated by the hygienist of each department.2 The treatment of test samplesThe samples of the test department include blood samples, body fluid samples and bacterial samples, etc. The test samples come from the patients, and most of them have a large number of germs or viruses, and they are the extremely dangerous sources of infection. The discarded urine, stool and other body fluid specimens, together with their disposable containers, should be placed in a large container containing effective chlorine disinfectant prepared in accordance with the requirements of soaking for more than 30min, fished out, packed in plastic bags and other tightly tied, sent by the health officer to a fixed incineration point for incineration.3 experimental waste disposal experimental waste, including: reagent boxes, reagent vials, enzyme labeling plates, sample head, bacterial identification of drug sensitivity plates. The outer package of the reagent box is treated as domestic garbage, and the used up reagent bottles should be classified according to the reagents firstly treated with acid or alkali, and then soaked in 84 disinfectant prepared according to the requirements for 30min, and then incinerated. Enzyme plates and sample heads are soaked in 84 disinfectant prepared according to the requirements for 30min, and then incinerated in disfigured form by the hygienist of each department. Bacteria used in the room swabs, disposable inoculation ring, culture medium, biochemical identification tube, bacterial identification of drug-sensitive plates and other high-pressure treatment, sent by the hygienist to a fixed point of incineration incineration.4 Instrumental excretion of waste disposal test waste liquid is mostly chemical substances, and some even contain toxic substances, and its environment, water and so on, will produce pollution. Now the laboratory commonly used instruments in the small equipment such as: semi-automatic biochemistry, plate washer, hemocoagulometer, blood rheometer, blood cell counter, blood gas analyzer, etc., the instrument is equipped with a special waste liquid collection barrel, some units of waste liquids full of direct pouring into the sewers without any treatment, which is very dangerous. For blood cell counter, hemoglobin determination, some use cyanide methemoglobin method, the waste liquid contains a large amount of cyanide, cyanide in the alkaline medium is stable, in the acidic medium, produces highly toxic cyanide, the waste liquid will be discharged directly into the sewer is very dangerous, general requirements must be in the alkaline and neutral conditions, and add sodium hypochlorite for the second level of decomposition. If you use SLS cyanide-free instruments for hemolysin, add a disinfectant with effective chlorine to the waste liquid as required and disinfect it before discharging it into the sewer. For trace element determination, some equipment uses mercury, and the waste should also be treated specially [1]. Mercury, including organic mercury and inorganic mercury, organic mercury waste solution by adding the appropriate oxidant decomposition of inorganic mercury, inorganic mercury waste solution adjusted pH 8 ~ 10, add soluble sulfide, due to the mercury is highly toxic, the filtrate is treated with activated charcoal before filtration and discharge. Nowadays, most of the immunization projects such as hepatitis series, syphilis, AIDS, etc. use ELISA method, and plate washer is used to wash the plates, and the waste liquid of the plate washer
