Visit medical waste disposal process GPS monitoring anti-drop halfway

What should I do with a used needle? How to deal with human tissue after surgery? Every day, the city produces a total of 15 tons of medical waste. Where did they arrive? There are many questions about how medical wastes are handled. Are they arbitrarily sold? Or is it a washbasin or raincoat? What is the treatment of medical garbage in Daocheng? On March 16th, we visited the entire process of transporting medical waste from transportation to incineration. During this period, in order to prevent the loss of medical waste, each contact must be re-weighed, signed, and GPS installed on the medical garbage truck, are not allowed to change routes and are not allowed to random parking.

A hospital is placed in a temporary place of medical waste. This is where the medical waste is generated. Cotton swabs, cotton cloth, and any objects that have been eroded by the patient's blood become medical waste. The task of the hospital is to classify and weigh the medical waste generated every day and hand it over to the medical waste temporary storage. All people who come into contact with medical waste must sign it.

At 8:30 am on March 16th, at the 13th floor of the Qingdao Fuwai Cardiovascular Hospital Ward, the head nurse was busy. The corner of the dispensing room was affixed with the label “Contaminated Area”. Mao Jianli of the Medical Department of the hospital introduced: “The job of the medical staff is to classify these wastes according to their infectivity and damage. For example, the infusion needles of patients need to be put in a sharp box first and then put into a yellow garbage bag to prevent the needles from being Garbage bags are punctured. The remaining needles, medicine bottles, and scissors are also put in the garbage bags."

Transport medical waste can enjoy advanced treatment, it has a special channel. Jiang Lili of the Dongyuan District Patient Service Center of the Municipal Hospital said: “It is a garbage ladder. This elevator cannot be used as anything but medical waste. It must be disinfected every day.”

Each hospital has a fixed medical waste collection cleaner, which is also in order to completely control the garbage. Qin Honghe, a staff member of the medical waste staging office of Qingdao Fu Wai Cardiovascular Hospital, has been dealing with medical waste for five years. He wears yellow garbage bags and dustbins with hats, masks and gloves every day. Qin Honghe said: "This task looks simple, but it is not at all sensible. All garbage coming in must be registered. I have kept all these five-year records. If you find any problems, you can check them out. ”

B. Transportation The city has 15 tons of medical waste that has been disposed of. In Daocheng, there is only one specialized organization that has formal qualifications for transporting medical waste: Qingdao Jiecheng Storage & Transportation Co., Ltd.

At 9:00 on March 16th, the medical waste transporter first came to Qingdao Fuwai Cardiovascular Hospital. Workers wearing rubber gloves and white hoods walked into the temporary storage of medical waste with a yellow bin. Their task is to safely dispose of the garbage bins that have been handled here on the garbage truck.

Many people will worry about the leakage of medical waste during transportation? Liu Tingqing pointed to the garbage truck and explained: “There are three layers of protection in the process of transporting medical garbage. The first layer is a yellow garbage bag and is packaged directly in the hospital. The second layer is a yellow garbage can. Our staff will treat the hospital daily. The rubbish bins have been removed and new sterile boxes have been left behind. The third layer of protection is our closed transport vehicle. With these three layers of protection, medical waste can never be leaked."

Liu Tingqing, manager of Qingdao Jiecheng Storage & Transportation Co., Ltd., said: “13 cars run every day. In addition to the urban areas, they have to go to Huangdao, Jiaonan, Jiaozhou and other suburbs. According to the requirements, medical wastes should be disposed within 48 hours after they are produced. In large hospitals such as doctors and municipalities, there is a lot of medical waste that is produced every day, and the staff have to take a trip in the morning and one in the afternoon and send them to the Laixi burning site for burning. Currently, there are about 800 hospitals and clinics in the city that sign with us. According to the agreement, the city’s medical waste generated in one day is estimated to be around 15 tons.”

It is understood that the current treatment fees for medical waste are charged at the rate of 1.5 yuan per bed, and the regulations of the Municipal Price Bureau in 2003 are still enforced.

Liu Tingqing said: "The garbage disposal in 2003 was a standard. Now it is another price. Together with the rise in oil prices, this price is very difficult for us."

The responsible person of the Municipal Environmental Protection Bureau also stated: "The standard of 1.5 yuan per bed is really the lowest in the country."

C treats two incinerations and the garbage becomes eligible for exhaust. It is known that the collected medical garbage is to be burned. Where can I burn it? How to burn? Everyone is unclear. Follow the garbage truck all the way to the destination: Located in Laixi's Qingdao Xintiandi vein industrial park, the city's medical waste is processed here.

In order to ensure safety, after wearing the N95 mask into the medical waste room, there are many green garbage transfer boxes. "There are a lot of germs in medical waste. Workers who directly contact the garbage should wear protective clothing, wear masks for basic protection when entering the workplace, and use UV lamps to sterilize the entire workplace. Each exposure takes 20 minutes to 30 minutes. "Li Feng, director of the Xintiandi Dispatching Office, said. In addition to the first step of feeding, the rest of the process is all mechanized.

The main workplace of medical waste is equipped with equipment for the entire incineration and exhaust gas purification process. Director Li said that after the waste is poured into the feed inlet, it enters a combustion chamber and is burned for the first time. The time is one and a half to two hours, and the temperature of one chamber is between 770°C and 1000°C. After burning, most of the waste becomes gas, leaving only a small amount of residue. Then, these gases enter the second combustion chamber for a second incineration. The temperature of the second combustion chamber is below 1150°C and only takes 4 to 5 seconds. "Bacteria and viruses can be killed at a high temperature of 1100°C. The role of this step is to further kill the bacteria in the combustion gas," Li introduced.

Most of the gas generated after the two combustions is gas, containing a large amount of sulfur dioxide, nitrogen oxides and other gases, the next three steps to be done is to deal with the tail gas. The final exhaust gas contains mainly carbon dioxide, nitric oxide, and nitrogen dioxide, which are emitted into the air and are completely harmless to the environment. The entire process staff will monitor the control room.

It is learned that from the feeding, incineration, and tail gas treatment, all the equipment is operated in 24 hours, and medical waste is continuously sent to the furnace warehouse, while continuously generating harmless exhaust gas through the stack. It takes about two hours to process a batch of medical waste, and it can process 15 tons of waste per day and more than 400 tons per month, which can fully meet the medical waste disposal needs of the entire city of Qingdao. After two burnings, disinfections, tail gas treatment, and chimney discharge, the remaining medical wastes from the combustion have no bacteria, but for the sake of safety, the remaining medical wastes are uniformly transported to landfills for landfill.

Director Li said that the landfill pits currently used are 150 meters long, 100 meters wide, and 6 meters deep. They are buried layer by layer from bottom to top. Each layer is sealed with two layers of leak-proof membranes to prevent leakage and affect groundwater. And soil quality is expected to be used for 20 years. After this pit is filled, it will be covered with soil, greened and will never be used for other purposes. "The landfilling of waste residue is the safest and most practical method of disposal," Li added.

How to ensure that medical waste is not "halfway missing"

With regard to medical waste, there have long been various statements in the workshop: They were sold privately and were made into washbasins and raincoats. In the interview, this issue has been circling in the minds of reporters. From hospitals to transportation to burning sites, how can we ensure that rubbish does not disappear "halfway?" People in hospitals, people in transportation vehicles, and people who burned their places shook their heads: “We have a medical waste transfer order, and we have full GPRS monitoring. Every step is very strict.”

Three-step one-signature is not easy to take away The hospital has a cleaner who collects medical waste, and directly connects with the medical staff. How to ensure safety in this link is not unexpected.

The staff takes the example of the placenta most concerned by the public as an example. In the hospital, three levels of checkpoints are required and three-step one-signature.

First: In the department there is a special hospital waste transfer registration book, which records the date, the name of the waste, the deliverer and the recipient. If the family member confirms that the placenta is handed over to the hospital, the family members will sign the medical records and sign the medical staff who took over.

Secondly, the medical staff put the placenta into the yellow garbage bag after freezing, and every day, the cleaning staff specialized in collecting the garbage will collect it at the door. At this time, under the supervision of the cleaner, the medical staff weighed and registered the placenta, and the cleaner signed it. After the two sides confirmed the error, they put a label on the seal of the garbage bag, which states: section, weight, date, and category. No one can dare to open the tag directly on the seal.

The third: The cleaners collected medical waste from the department to the temporary store of the hospital. At this time, they had to sign. The signing parties were between the cleaner and the temporary deposit, and they were again weighed and registered.

Under such strict regulations, even a cotton swab will not disappear.

After the GPS on the transport route traces the transport vehicle to the hospital to collect medical garbage, both parties must sign it, indicating the number and type of bins as well as the handler. If the previous stages have been monitored or inconveniently operated in the hospital, will the hidden danger of garbage trucks increase?

The staff of the emergency department of the Municipal Environmental Protection Bureau Supervision Detachment explained in a small way: “This is not even! After the garbage has been placed on the transport vehicle, the vehicle has GPS, and each vehicle’s walking route is fixed. It cannot be changed casually. parking."

At the same time, Xiaoyan said that in addition to GPS monitoring, the "Medical Waste Transfer" required by the Ministry of Health is also an important means to ensure the safety of medical waste disposal. “Five-joint bills mainly include medical waste generation units, transport units, receiving units, and quantities. The EPA, the health bureau, the production units, the transport units, and the receiving units each hold one unit, so that the flow of medical waste can be achieved. Well documented."

The people who do this living must have the strength to transport medical waste. Most people cannot do it. Therefore, there are currently nearly 40 medical garbage transport workers in Qingdao Jiecheng Transportation Company, all of whom are between the ages of 20 and 40.

The 25-year-old Wang Chaolu is one of them. He has to drive medical waste. The old man in Heze has been doing this work for 4 years. He said: “Just after a few days I knew what it was like to transport medical garbage. I was still a little scared. One time they told me that this box had to be taken care of. There was still some tumor on the thigh after surgery. Suddenly my heart trembled, and some people saw our car was scared and we were not allowed to stop at the entrance of the community or at the door of the house.” But these feelings were already numb for 4 years, and now the dynasty Lu was no longer afraid of facing these things.
