Clean room door and window gap treatment: Generally speaking, clean room doors and windows have three types of structural gaps. The first category is: the combined splicing and the installation gap between the door and the clean room door; the second category is: the overlap gap between the door and the opening fan; the third category is: the installation gap between the glass or other core boards. The nature is different and their proportions on the clean room doors and windows are also different. Therefore, the airtight measures adopted for the airtightness of clean room doors and windows are not completely the same.

  Fixed gap treatment: Not only is the number of installed gaps in each clean room relatively small nowadays, but the combination of the door and the opening is relatively hidden after decoration, and it is a fixed gap that is easier to seal. The connection between the rib and the periphery of the hole should be firm, not only for the closed clean room doors and windows, but also the requirements of the general clean room door structure. Due to the large and fierce force of the clean room door, special attention should be paid to the process and the fixing of the clean room door. Whether the fixed points around the opening are firm and stable, but for closed clean room doors and windows, it must also be emphasized that the gap between the chamber and the clean room door or the hole should be tightly filled, and then covered with indoor and outdoor wall decoration layers. The air tightness of this type of gap is basically guaranteed. The second type of fixed gap is the installation gap of glass or other core panel.

The treatment of the movable gap: How to overlap the opening fan of the clean room door and the frame material is the key to the design of the clean room door seal. The gap in the lap joint is different from the fixed gap. Because the movable fan needs to be opened, the wood can adopt the "one-and-for-all" sealing measures. Compared with Zhou, the opening fan of the clean room door is larger, and the movable gap occupies a larger proportion of the total structural gap of the clean room door. The number of openings of the clean room door is much more frequent than that of the clean room. The working conditions of the gaps around the door leaf are also more complicated. Take a single flat open clean room door as an example. The two sides along the vertical direction are small. The side with the handle is often subjected to various frictions or collisions during passage, and the side with the hinge is The direction of force applied to the bore due to the rotation of the fan is completely different from the other three sides.

Operating room laminar flow air supply ceiling-clean air supply ceiling is the clean operating room, the purifying air supply end of the laminar flow ward, it has the functions of high efficiency filtration, flow sharing and air flow compensation. The rationality of the structure of the laminar flow purifying air supply ceiling directly affects the air supply effect and purification level of the operating room. KLCFILTER laminar flow air supply ceiling is the crystallization of the experience and practice of operating room air supply terminal in the past ten years. This type of terminal has been used in nearly a thousand operating rooms. Its superior performance and unique double-layer DPP flow-sharing network energy The airflow is evenly sent to the working area, and the central airflow compensation device can effectively eliminate the influence of updraft caused by the heating of personnel and equipment on the laminar flow. To Operating room laminar flow air supply ceiling-clean air supply ceiling Working principle: The air supply ceiling consists of a high-efficiency air disinfection and filtration system, a fan power system, a noise reduction system, and an operation control system. When working, the fan inhales ambient air, filters it into clean and sterile air through the air purification and disinfection system, and then delivers clean air to the hospital bed area in the cover in a laminar flow, while maintaining a positive pressure in the cover to prevent dust in the external space Particles and microorganisms enter the hood. With the rapid development of modern medical science and technology, surgical technology has increasingly higher requirements for the clean conditions of the operating room. The 100-level laminar flow operating room is currently the most ideal. However, how to effectively manage the number of air colonies in the laminar flow operating room to meet the air environmental hygiene standards issued by the Ministry of Health, and to meet the clean operating room grade standards, and to reduce it to a minimum. There are few domestic search documents and data. A new topic worth discussing in the management of clean operating room. Laminar flow air supply ceiling adopts air cleaning technology to control microbial pollution in different degrees to achieve the requirements of air cleanliness in the controlled space environment and suitable for various operations; and provide suitable temperature and humidity to create a clean and comfortable operating space surroundings.

Features of laminar flow ceiling:

Hospital operating rooms have very high environmental requirements. How is the air filter installed in the hospital operating room? Today we will introduce the installation principle of the air filter in the hospital operating room.

To An air filter in a hospital operating room generally consists of two parts: three air conditioners and two purifiers. The working principle of medical air filters is divided into eight parts:

Part 1: Return air section The return air section means that the air volume sent by the exhaust fan reaches the specified air volume, and the recovery system of the medical air filter can send out air.

Part 2: Primary filtration Primary filtration is the first filtration procedure performed by non-wind. In this step, we need to replace or clean the equipment for a certain period of time.

Part 3: Heating process The heating process is generally an electric heating process used for heating in winter.

Part 4: The humidification stage of the medical air filter The humidification stage is mainly to humidify the blower unit through a humidifier, and then reach the temperature for people's affairs.

Part 5: Secondary Filtration This is the final filtration stage of the air filter in the hospital operating room. This stage is the final pass to ensure air quality. The air is filtered once, then humidified, and finally filtered again. This ensures the purity of the air and can achieve the medical air filtration effect. Then the filtered air is output.

Disinfectants and electronic sterilization devices are necessary daily cleaning items in every family. Especially in the season of a high incidence of influenza and other infectious diseases, the frequency of use of disinfection products will increase significantly. Home UV sterilizers are the most common electronic sterilization devices in modern homes, and because of this year's special circumstances, many new types of UV sterilization devices are being accepted by consumers faster, including home UVC Air sterilizers, UV cutting board sterilizer, etc.

So what are the advantages of UV sterilization? Why has it become the preferred method of disinfection?

Effective Against More Germs

UV sterilization is a physical sterilization method that directly acts on the genetic material in biological cells. It destroys DNA and RNA to achieve the purpose of killing bacteria and viruses. Therefore, except for a few rare super bacteria, UV sterilization can effectively kill most bacteria and viruses. For the common germs in the home environments, efficient UVC germicidal lights are enough to meet cleaning needs

Fast & Efficient

UV rays are very efficient at destroying DNA and RNA. UVC rays of sufficient intensity can even kill bacteria within 1 second. So UV sterilization is very fast, but the sterilization time preset in different UV sterilization device is usually different because of different cleaning needs. For example, a LED UV sterilizer boxthat for cleaning daily small items just needs 5 minutes to achieve the required sterilization rate, and a high-power UV sterilizer used for sterilizing the medical device usually rules the sterilization time as 30 to 60 minutes.

Non-contact, No chemical residue

UV sterilization is carried out by light irradiation, and the cleaning work can be completed without touching the objects, which is very sanitary and convenient for the operator. And because of the characteristics of light, it will not leave any chemical by-products on the object after sterilization. So, UV sterilization is more safe and friendly to both the environment and users.

Energy Saving

UV sterilizers are representative of low energy consumption in electronic disinfection equipment. The daily power consumption of some small UV light air purifieris even less than 0.2 kwh.

At present, UVC LEDs, which are more energy-efficient and efficient than traditional fluorescent tubes, have been widely used in more products. It is believed that many UV sterilizers will have better energy-saving performance in the near future.

Low Cost

The UV sterilizers are the disinfection equipment with a mature technology that has been used for many years. Most of the UV sterilizers just need simple maintenance and their service life can reach thousands to tens of thousands of hours. This is a cost-effective way of sterilization and cleaning method for most families.

Because it has so many obvious advantages, ultraviolet sterilization has become one of the most trusted and favorite methods of disinfection. However, it should be noted that UV also has some shortcomings, users still need to follow the instructions carefully to use them, to safely and effectively use UV to complete the sterilization work.

If we can turn container into homes, then surely we can turn shipping containers into one of our homes’ greatest accessories — pools. One company is doing just that-CBOX， who is a design company specializing in transforming containers into houses, and recently it has launched a project to transform containers into swimming pools.

The swimming pool has a built-in hot water system that can be raised by 10 degrees Celsius per hour, and the swimming pool can be divided into hot and cold water areas through a dedicated dividing plate to experience different water temperatures. Compared with traditional swimming pools that need to be dug, the installation method ofswimpoolsis much more flexible and does not have too high requirements on the soil. If you put it directly on the ground, you can also enjoy the scenery outside through the "window".

Shipping containers are naturally durable and structurally sound,Repurposing a shipping container cuts down the carbon footprint and turns something that may have not been useful into what we think is a lifestyle changing, modern asset.

Modpools are just 50 percent of the cost of conventional in-ground pools, and come with a hot tub and pool area that can be separated in the cold months. That means you can decide which portion to heat, and enjoy the separate benefits of both a pool and a hot tub, all for one comprehensive price.

shipping container pools would be easy to install ？

A pools ship completely ready to use with all the pool equipment built in. With some light ground prep, power and gas access, you can simply plug and play。which features a window on its side, can be installed where traditional in-ground pools can’t be. Many people have ground that is too hard because of rock or, alternatively, have ground that is too soft because of high water levels. We can be placed above ground with decks built around, partial in-ground behind retaining walls or completely in-ground. We find many of our customers want a pool but are unable to have a traditional pool installed.

And because it’s easy to install, it’s also easy to move — that means no more leaving your pool behind when you move. This is a vast departure from a traditional pool, and makes our pools a smart lifestyle and financial choice.

The hospital’s clean room is a biological clean room. The hospital’s biological clean room is airtight. After reasonable zoning, process design, air purification and other construction links, it can effectively reduce cross-infection and control the spread of bacteria and viruses in the air. During the construction, Wiskind Cleanroom discovered that the biological clean rooms of many hospitals have hidden dangers of congenital deficiencies, and there are many social problems such as concept, plan, design, equipment configuration, construction technology and so on.

1. Can the positive pressure clean operating room operate on patients infected by this epidemic?

The main route of transmission of this epidemic is droplets attacking the respiratory system and mucous membranes through the air. At the same time, droplets are also contaminated on the surface of objects and are transmitted through human contact . The transmission routes are multi-directional. It is recommended that such infected patients should be operated in a negative pressure operating room. However, if there is no negative pressure operating room in the operating department of some hospitals, and the patient must perform the operation, the operation should be arranged in an operating room with a separate area as much as possible.

2. If an operation is performed on a severely infectious patient in a positive pressure clean operating room, how to disinfect the purification unit system?

After the positive pressure clean operating room is operated on patients with severe infectious diseases, the disinfection requirements are the same as those of the negative pressure operating room. In addition to the operating room to cleanroom wall panels , roof, floor, cleanroom door, outlet and all indoor facilities and equipment to conduct a comprehensive, thorough, serious, no dead outside cleaning disinfection, but also carefully clean up all the gaps, strict disinfection.

In terms of purifying the air system, the professional team of professionals should replace the return air filter, the circulating unit filter, the air supply port (or air supply ceiling) high-efficiency filter, and the exhaust system filter under the premise of self-protection. , The replaced filter should also be disinfected, sealed and then disinfected.

Carry out careful and thorough disinfection of air ducts participating in circulation and discharge and fresh air supply ducts without check valves. It is best to use atomized hydrogen peroxide for air duct disinfection.

It is also necessary to carry out disinfection and sterilization measures for the participating unit systems, which mainly refer to the circulation unit, the inside and outside of the exhaust fan unit, and the computer room.

3. What is the main difference between a positive pressure clean operating room and a negative pressure operating room?

The positive pressure clean operating room is an operating room with clean levels (level I , II , III , IV ). Its air system is composed of treated clean fresh air + circulating clean air with different air changes + exhaust air , That is, there is fresh air, circulating air, and exhaust air. The starting sequence of the fan should be fresh air, circulation and exhaust air. The volume of fresh air sent to the operating room is greater than the volume of exhaust air. The relative pressure in the operating room is greater than the pressure in the adjacent room. Its protection objects are mainly surgical patients. Because the exhaust vent of the clean operating room is mostly designed on the top of the operating room, the exhaust fan is a single fan system, and the exhaust air does not need to be equipped with a high-efficiency filter, but only a junior high-efficiency filter.

The negative pressure operating room is generally an operating room with no cleanliness level. Its air system is composed of treated clean fresh air + exhaust air, that is, direct delivery and direct exhaust. The starting sequence of the fan should be exhaust air, fresh air, and the fresh air volume sent to the room is less than the exhaust air volume. The relative pressure in the operating room is less than the relative pressure in the adjacent room. Its protection objects are mainly medical staff and the surrounding environment. The air outlet of the negative pressure operating room should be located at the lower end of the side wall of the operating room close to the patient's head and on the side of the top anesthesia work area. The exhaust fan system is a double fan. The exhaust air must be equipped with a high-efficiency filter.

4. How can we know that the clean room and related controlled environment of our hospital are safe during use?

The main purpose is to be "controllable" and "knowable" for the key parameters designed in accordance with the relevant national standards for the clean room and related controlled environment of our hospital. That is to say, the use process of the clean room and related controlled environment in our hospital is a dynamic process (infection also occurs in the dynamic process), and various parameters of the environment are realized in the dynamic process. Real-time monitoring and management of parameters can realize whether the environment is safe or not. However, the clean rooms and related controlled environments of most hospitals in our country do not have real-time management configurations, so it is basically impossible to know whether our own clean rooms and related controlled environments are safe. This is a shortcoming in the construction and use of clean rooms and related controlled environments in our national hospitals.

Some hospitals now install pressure display devices in clean rooms, so that you can know whether the air in the clean room is leaking and the general situation of organized air flow. However, the pressure of many hospitals shows that the values displayed by the facilities are ridiculously deviated, which can mislead us.

At present, the method of bacterial sampling and culture readings in clean rooms and related controlled environments in hospitals can most directly reflect the safety status of hospital clean rooms and related controlled environments. Although there are many indicators for the safety factor of hospital clean rooms and related controlled environments, they are comprehensive, but the bacteria indicators are the most critical and important. However, it takes a long time for bacterial samples to be cultured and the feedback of safety information is delayed. If it is in an extraordinary period of the fight against the epidemic, it is recommended to increase the time density of bacterial sampling and analysis in key areas.

5. If the hospital is to rebuild some negative pressure isolation wards in the existing buildings, what aspects should be paid attention to?

MasterCard believes that the most critical issue in the construction of negative pressure isolation wards in hospitals is the concept. Although the negative pressure isolation ward of the hospital and the clean operating room, ICU , supply room, liquid distribution center, laboratory, etc. are all controlled environments, the negative pressure isolation ward is not a clean room and does not require expensive air purification systems.

Negative pressure isolation wards are mainly used to treat patients with respiratory infections. The principles that must be followed when designing are to control the air transmission of the virus, cut off the air transmission chain of the virus, and simultaneously implement physical separation and air isolation of the source of infection. When designing, we must insist on: zone prevention and control, layer by layer check; process safety, reasonable and convenient; isolate the source of disease and cut off transmission.

It is best to use a dual-channel mode for partitioning, which can be divided into clean area, semi-contaminated area (also regarded as a buffer zone), ward area (contaminated area), and other auxiliary areas. Each area can be an independent area, and each area is divided or connected in the form of a buffer.

The flow of people and things must be "buffered." Each area requires functional satisfaction and complete equipment. All items that need to be removed from the contaminated area and semi-contaminated area, especially patient excrement and medical waste, shall have special areas for disinfection, sorting and packaging, and re-sterilization.

The air isolation system uses an organized gas flow pattern. The air supply in polluted and semi-polluted areas adopts full delivery and full exhaust. The fresh air should be treated, with initial, medium and sub-high efficiency filter sections. The exhaust fan unit should be equipped with dual fans, one fan is used and one is prepared, and the standby fan can be quickly started. The external discharge of the exhaust system must pass through a high-efficiency filter section, and a qualified and effective check valve must be installed. The exhaust vent must have a certain height, and the discharge direction must be reasonable.

Arrangement of air supply and exhaust vents: The air supply vent of the isolation ward should be located at the top of the side where medical staff enter the operation area of the ward, and the exhaust vent should be located on the underside of the wall near the patient's head in the bed. The air outlet for the buffer zone should be located at the lower end of the wall near the isolation ward. The air outlets of the clean area are arranged according to the position of the air-conditioning outlets of the normal normal office area. The temperature of the isolation ward should be set not less than 22 ℃, and can be moderately higher if possible.

Pressure gradient setting: For the design of a completely independent indoor negative pressure isolation ward, it is best to have a positive pressure buffer channel at the beginning of entering the area, and use positive pressure to protect and separate other areas. The clean area is normal pressure Zone, the buffer zone starts as a negative pressure zone. The isolation ward and the sewage treatment and disinfection room are the main negative pressure area, and the pressure gradient is the highest negative pressure in the entire area.

The number of air changes is set to 12 , which does not mean that fresh air must be sent in 12 times and the air volume must be discharged 12 times. The American standard is also 12 times of air change, but they only send in fresh air for 2-4 times and discharge 12 times of air. The large amount of 8-10 times air volume is the air volume leaked from other areas. The door of the negative pressure isolation ward does not need an airtight door, and it is normal for other areas to vent into the air.

In addition, the operating parameters of the negative pressure isolation ward should be set to remote real-time monitoring mode. The isolation ward should be equipped with high-definition video screen equipment to remotely observe the patient's condition in real time. The sewage discharge from the negative pressure isolation ward is not allowed to be directly discharged to the corresponding sewage discharge system of the hospital. The sewage must be equipped with disinfection equipment and can be discharged after disinfection.

The use of negative pressure isolation wards to treat severely infected patients is an effective means to control the source of infection and cut off the air transmission chain. The hardware construction is one aspect, and the other aspect: use and management are equally important.

Through research over the past few months, many scientists from all over the world have proved that UV can effectively kill the COVID19. As recently as July, researchers from Columbia University said they had solid evidence that UV could effectively kill coronaviruses, including COVID19, H1N1 flu viruses etc. Scientists believe that this study provides a new weapon and theoretical basis for the fight against this epidemic.

Before this, many innovative companies invested their technological power in the innovative R&D of ultraviolet products ahead of time because of the prediction of the market and tech. Until now, there have been a number of new UV products on the market, and most of them have got positive feedback from the market.

Masks are important protective equipment that has attracted much attention in this epidemic. Recently, several new UV sterilization masks have displayed on some well-known online crowdfunding platforms. Tech companies combined UVC germicidal light into traditional filter masks to develop new products with disinfection and self-purification functions. These UV germicidal masks are popular with consumers while they just hit the market, raising millions of dollars each on crowdfunding platforms in just over a dozen days.

UV makeup brush sanitizer is also a kind of new product that is very popular in the market at present. Compared with the ultraviolet disinfection mask, the UV tool sterilizer box dryer is a micro-innovation of products by professional disinfector manufacturers. Combine the beautiful desktop storage box with UVC disinfection technology, with sufficient disinfection room, beautiful looks, unique germicidal drying function and clean storage function. The launch of this product not only meets the needs of disinfecting small daily items during the epidemic, but also meets the daily needs of many people to store clean items. So, this product has been included in the purchase list by many professional buyers as soon as it was launched.

Not only these, but also many innovative products using ultraviolet disinfection technology, such as UV air cleaner specializing in disinfection air, Smart elevator UV cleaner Light with automatic cleaning function, and so on, have become the most popular product choices in the current market. And it is believed that in the coming future, there will soon be more innovative UV devices recognized by consumers on the market.
