Description

Technical Field

[0001] The present invention relates to the field of virus isolation, and in particular to an integrated modular negative pressure isolation ward. Background Art

[0002] Effective isolation and protection of personnel requires standard modular biosafety negative pressure isolation wards to prevent leakage of infectious sources suspended in the air. The importance of modular biosafety negative pressure isolation wards is valued by various medical institutions; there are currently many problems in the construction of isolation wards in China, and unified standards are urgently needed for design, construction, and acceptance. Even if relevant isolation ward design specifications or acceptance specifications are issued in the near future, there is still a lack of operational guidance standards suitable for owners.

[0003] For owners, the design or construction specifications of isolation wards are often too professional and complicated, and it is difficult for medical system staff who are not from mechanical and electrical related majors to understand and use them. For design and construction units, it is necessary to better understand the needs of owners when meeting the requirements of the specifications, and build isolation wards that meet the different levels of needs in different regions according to local conditions.

[0004] Therefore, the standard for the basic requirements of clean equipment construction and configuration of modular biosafety negative pressure isolation wards, which is relatively simple and clear and suitable for use by owners and contractors, has become a problem that continues to be solved in the construction of isolation wards in China. Owners can use the basic configuration requirements in the standard as a basis to supervise the design and construction units, and can also be used as an evaluation standard for the construction of isolation wards within the system by the health department.

[0005] In recent years, the research and construction of clean equipment engineering for negative pressure isolation wards has been gradually developing in my country. Negative pressure isolation ward clean equipment engineering is mainly used to isolate patients with respiratory infectious diseases. The pathogens of such patients can be transmitted through non-direct contact routes such as human breathing, droplets and air. It is necessary to maintain negative pressure in the room to prevent the indoor polluted air from spreading outward and causing regional infection. However, the clean equipment engineering of negative pressure isolation wards is a complex system construction. Investment project establishment, site selection, design, construction, acceptance and other links all require careful and comprehensive consideration and professional technical knowledge and strength. At present, various places are only building according to their own economic conditions, ideology and relatively limited technical knowledge level. Therefore, the construction level is uneven and the ability to respond to emergencies is limited.

[0006] According to the engineering inspection, testing and diagnosis of negative pressure isolation ward clean equipment projects in many domestic infectious disease hospitals by the Purification Testing Room of the National Construction Engineering Quality Supervision and Inspection Center, we found that there are many problems in the construction of negative pressure isolation ward clean equipment projects in China, which are mainly reflected in the lack of specifications and standards, non-standard design, low construction quality and incomplete acceptance standards.

[0007] As mentioned above, there is currently a lack of highly targeted professional design specifications in China, and the awareness of design units in various places on the clean equipment engineering of negative pressure isolation wards needs to be improved. The clean equipment engineering of negative pressure isolation wards has its own characteristics in terms of its plane layout, personnel flow and logistics, ventilation and air conditioning system, water supply and drainage system, etc. However, some design units lack basic theoretical knowledge of isolation, and do not consider zoning (clean area, semi-contaminated area and contaminated area) in the layout, do not consider unidirectional flow in the air flow organization, and the pressure gradient is not clear. Problems: 1. The content of the ventilation and air conditioning construction design drawings is incomplete, lacking indoor parameter requirements for isolation wards and ordinary wards, lacking necessary cross-sectional drawings or instructions, and lacking necessary technical requirements and instructions for equipment such as air conditioning units and high-efficiency filters. The design does not comply with the provisions on the depth of design documents in Article 4.7 of the "Regulations on the Preparation Depth of Construction Engineering Design Documents" of the Ministry of Construction of the People's Republic of China, which came into effect on June 1, 2003. 2. The return air outlet (section) of the isolation ward is not designed with a high-efficiency filter, and the system exhaust fan does not have a backup fan. 3. The description of exhaust control in the design and construction instructions of the drawings: "The exhaust fan is linked to the purification air conditioning unit. When the purification unit is turned on, the exhaust fan is turned on accordingly. When the purification unit is turned off, the exhaust fan is turned off accordingly." is wrong. If it is operated according to the design, it will cause positive pressure in the negative pressure room during the opening and closing process, causing pollutants to leak out. 4. The contaminated corridor is not equipped with ventilation and air conditioning facilities, which is not conducive to the formation of an orderly pressure gradient. 5. The buffer room of the ward used to treat suspected patients is not equipped with any ventilation measures, making it difficult to form the necessary pressure gradient, which will cause pathogenic microorganisms to spread in the building. 6. In some designs, some fresh air outlets are less than 3m away from the adjacent exhaust outlets and are located above the exhaust outlets. Some fresh air intakes are located near the drainage riser vents. The drainage vents are located on the upwind side of the fresh air outlets or are too close, and the polluted air emitted by the vents and blown out of the exhaust outlets are easily sucked into the fresh air outlets.

[0008] The negative pressure isolation ward clean equipment project is mainly to control infectious diseases that can be transmitted through aerosols. In order to prevent the air in the isolation ward from spreading to the outdoor environment or other rooms to cause infection, maintaining negative pressure in the ward is one of the most effective means. At the same time, through isolation treatment, infectious patients, ordinary patients and healthy personnel are treated separately, which greatly avoids the possibility of cross infection and facilitates the individual treatment and care of infectious patients. At the same time, isolation treatment is also convenient for the disinfection of pollutants, narrowing the scope of pollution and reducing the chance of infectious diseases. 1. It is best to set up an isolation ward separately. If the conditions are not met, it should be on one side of the building and form a zone. 2. The main principle of the negative pressure isolation ward clean equipment project is physical isolation, mainly through the isolation of the building itself and the negative pressure isolation formed by the air conditioning system. In general, the negative pressure isolation ward clean equipment project should consist of wards, independent toilets, buffer rooms, corridors, etc. 3. At the same time, the area is divided according to the severity of the pollution. It can generally be divided into contaminated areas, semi-contaminated areas and clean areas. Buffer rooms should be set between different areas to further reduce the possibility of pollution spread. Summary of the invention

[0021] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0022] (1) The present invention establishes a temporary accommodation area for medical staff, a duty area, an office area, a medicine dispensing area, a protective dressing area, a treatment area and a negative pressure isolation ward area in a modular manner, which can effectively prevent the spread of viruses in the isolation ward and to the outside world, and has a significant isolation effect, which is beneficial to virus isolation treatment and epidemic prevention and control.

[0023] (2) The layout of the present invention adopts a dual-channel arrangement, has good natural ventilation and natural lighting conditions, and establishes "three zones, two belts and two lines" in the ward area; three zones: clean area, semi-contaminated area, and contaminated area; two belts: two buffer zones are established between the clean area and the semi-contaminated area, and between the semi-contaminated area and the contaminated area; two lines: inner corridor and outer corridor, with clear boundaries of closed partitions.

[0024] (3) The usable area of ​​the modular biosafety negative pressure isolation ward of the present invention is generally a single room with an area of ​​not less than 15m², and the room width is more than 3.3 meters; the width of the corridor in the treatment area is generally more than 2.4 meters, and the width of the corridor in the office area is generally not less than 1.2 meters except for meeting the fire evacuation requirements; the air flow direction of the present invention is achieved by pressure gradient control, and the air flows from the higher pressure area to the lower pressure area, and all return air must use the lower return air, and the medium efficiency filter is installed on the return air outlet.

[0025] (4) The shower room of the present invention forms a fresh air circulation system through the air supply component and the exhaust component, and forms a negative pressure environment of about -5Pa to -10Pa in the shower room. At the same time, the air supply component and the exhaust component are both provided with high-efficiency filters, which can filter or sterilize viruses in the air, and can effectively prevent the air in the shower room from spreading to the outside. The fresh air maintains a negative pressure to improve the comfort of the human body; the present invention sprays clean water or disinfectant water through the shower head, which can flush away various harmful substances that may be contaminated on the human body from the body by showering, and then the sewage collector collects and treats it centrally.

[0026] (5) The air shower room of the present invention collects external fresh air through the fresh air collection port, filters it, sterilizes it, and then transports it to the air shower device. The air shower device performs air shower treatment on the human body to eliminate toxic substances, viruses and bacteria on human clothes and in the air. The air is then discharged through the return air plate, exhaust duct, and exhaust box to form a set of circulating fresh air and air shower system, which continuously performs air shower operation on the human body. The combination of air shower and disinfection ensures the removal of viruses in all directions without dead angles. At the same time, the circulating air, whether it is the incoming air or the exhaust air, is strictly filtered through the BIBO high-efficiency filter to ensure the cleanliness of the air in the air shower room.

[0027] (6) The air shower room of the present invention can blow out strong clean airflow from multiple directions at the same time. The airflow is driven by a high-efficiency centrifugal fan, so that the dust is attached to the primary filter or isolated outside the high-efficiency isolation net, so that the attached dust and unclean objects remain on the surface of the human body or product, ensuring the cleanliness of the purification space.

[0028] (7) The ultrasonic atomizer of the air shower room of the present invention can be added with a static electricity removal function to eliminate the static charge carried by the human body or the goods themselves. It avoids the static electricity adsorption effect and makes the dust removal more thorough. At the same time, it also avoids the possibility of damage to electronic components due to static electricity. It is an ideal protective equipment for high-precision production workshops.

[0029] (8) The present invention can be an integral type or a modular assembly, and is easy to disassemble and assemble; it adopts a special door panel structure to prevent water containing viruses from leaking into the space outside the door and causing contamination.

Items used by patients are sterilized by pressure steam sterilization, ultraviolet irradiation, disinfectant immersion, wiping, fumigation and other methods; b. Domestic waste and other waste generated by patients are all medical waste, which are collected in the contaminated channels of each ward and packed in double-layer medical waste bags or sealed disposable medical waste barrels, and then received, transported and incinerated by designated personnel; c. Patients' excrement and domestic sewage are discharged into an independent sewage treatment system for disinfection, and then discharged into the hospital sewage system for safe discharge.

[0050] 4) Infection control requirements: a. Depending on the area where the medical operation is carried out, due to the different degrees of danger of contact with pollutants, graded protection is implemented, that is, the clean area, semi-contaminated area, and contaminated area are respectively subject to different protection requirements and clothing, with clear signs and no overlapping passage processes.

[0051] Each ward (i.e. negative pressure isolation ward) is generally an independent air conditioning system. To ensure the pressure gradient, the fan adopts variable frequency control. If the ward's air system can also use partial circulating air return, the return air outlet must use a "dynamically sealed negative pressure high-efficiency non-leakage exhaust device" and must be equipped with a high-efficiency filter, otherwise, it will be quite unsafe.

[0052] 2) An independent air-conditioning system shall be installed in the public treatment area, and separate air-conditioning systems shall be installed in the clean area, potential contamination area and dirty area.

[0053] ② Airflow organization form:

[0054] Ward airflow organization:

[0055] a. The air flow organization should eliminate dead zones, stagnant zones and avoid short circuits between supply and exhaust air.

[0056] b. The supply and exhaust vents in negative pressure isolation wards are generally located on the end wall of the bed. Clean air should first flow through the area where medical staff may stay in the ward, and then flow through the source of infection (mainly the patient's head) into the exhaust vent. In this way, medical staff will be upwind of the air flow and will not be between the source of infection and the exhaust vent. The supply vent is arranged on one side of the room, opposite to the patient, and the exhaust air is discharged from the downwind side of the patient's head. The airflow organization is usually affected by the air supply temperature difference, the exact location of the supply and exhaust vents, the placement of medical equipment and furniture, and the activities of health care personnel and patients. The bottom of the exhaust vent should be at least 100mm above the floor of the room.

[0057] Airflow directions in public treatment areas:

[0058] a. Pathogenic agents may spread to other parts of the isolation area, so the isolation area should be designed with directional airflow. The airflow should flow from the clean area to the non-clean area.

[0059] b. The air supply in the public treatment area must allow clean air to flow through the areas where medical staff may stay first. The air flow should flow from the corridor to the isolation ward to prevent the spread of pollutants to other areas. The air flow direction is achieved by pressure gradient control. The air flows from the higher pressure area to the lower pressure area, and all return air must be returned from the bottom, and a medium efficiency filter is installed on the return air outlet. See Figure 1-3 Airflow diagram of negative pressure isolation ward.

[0060] ③ Ventilation frequency and cleanliness requirements

[0061] For details, please see DB11 / 663-2009 "Basic Requirements for the Construction and Configuration of Negative Pressure Isolation Wards", which is generally 6-12 times per hour.

[0062] ④ Determination of pressure gradient

[0063] 1) In order to strictly control the contamination of pathogenic factors to other areas, isolation wards should generally have an antechamber (buffer room or airlock room).

[0064] 2) A certain negative pressure gradient should be maintained in the isolation ward, with the pressure decreasing from corridor to anteroom to isolation ward.

[0065] 3) The negative pressure value in the ward should be 10Pa lower than that in the buffer room, but the specific negative pressure value should be determined according to the negative pressure gradient value between the three independent compartments of the ward, bathroom and buffer room. The negative pressure gradient refers to the orderly gradient pressure difference between the ward, bathroom and buffer room of the negative pressure isolation ward to ensure that the airflow flows in a directional manner from the low-pollution area to the high-pollution area. Undoubtedly, as a passage for medical staff, the air in the buffer room is the cleanest compared to the ward and bathroom, so the air pressure in the buffer room should be positive pressure relative to the ward, generally not less than 10Pa. The air pressure in the buffer room is 15Pa relative to the patient's bathroom, the air pressure in the public treatment area is not less than 15Pa relative to the buffer room, and the air pressure in the public treatment area is not less than 10Pa relative to the outdoors.

[0066] ⑤ Exhaust treatment

[0067] In order to prevent environmental pollution, exhaust air must be treated. There are many ways to treat it, such as high-efficiency filtration, ultraviolet disinfection, high-temperature disinfection, etc. As for which method to use, we believe that air filtration is one of the most effective methods. What level of filter should be used for exhaust air? We believe that high-efficiency filtration of no less than Class B should be installed at the indoor return (exhaust) air outlet.

[0068] ⑥ Indoor noise requirements for negative pressure isolation wards: Indoor noise shall not exceed 50dB.

[0069] ⑦ Energy conservation and environmental protection issues

[0070] Since most negative pressure isolation wards use fresh air ventilation and air-conditioning systems, the energy consumption will be relatively large. When designing the system, some new energy-saving measures should be adopted as much as possible, such as ethylene glycol heat recovery system, to minimize operating costs.

[0071] The exhaust air energy recovery system can be equipped with an energy recovery device, but in order to prevent cross-contamination between supply air and exhaust air, a full heat recovery device cannot be used.

[0072] 2) Reasonable HVAC system design.

[0073] ⑧ System requirements for accessories and air conditioning equipment

[0074] The air conditioning unit adopts a dual fan or backup fan system. When a fan fails, it can automatically switch to the backup fan to ensure that the ward maintains a negative pressure state.

[0075] The exhaust box adopts a double-exhaust fan system, which can automatically switch to the backup fan after a fan failure to ensure that the ward remains in a negative pressure state.

[0076] Air conditioning units that meet sanitary cleanliness requirements must be used.

[0077] An ultraviolet germicidal lamp is installed in the air conditioning unit.

[0078] 5) The silencer or silencer elbow adopts a double-chamber microporous plate silencer.

The exhaust assembly 712 includes an exhaust sealing cover plate and an exhaust fan. The exhaust fan is installed on the exhaust sealing cover plate. An exhaust port connected to the exhaust fan is provided on the exhaust sealing cover plate. The exhaust fan is connected to a high-efficiency filter B. The high-efficiency filter B has an air outlet connected to the inside of the shower room. A hot water pipe 751 and a cold water pipe 752 are provided in the shower pipe layout area of ​​the shower room. A shower head 75 is installed on the top of the room of the shower room. The shower head 75 is connected to the hot water pipe 751 and the cold water pipe 752 through a spray pipe 753. An electric control box A76 is installed on the top of the shower room. An internal control panel 78 is provided in the room of the shower room. A door opening button B that matches the electromagnetic lock B is provided on the internal control panel 78. An entry side control panel 74 is provided on the outside of the welding side panel A73. A door opening button A that matches the electromagnetic lock A72 is provided on the entry side control panel 74. A light assembly 714 is installed in the light installation area of ​​the shower room.

[0080] like Figure 2 to Figure 6 As shown, a sewage collector 710 is provided at the bottom of the shower room, and the sewage collector 710 is connected to a drain pipe. An emergency stop button A is also provided on the internal control panel 78, and an emergency stop button B is also provided on the entry side control panel 74. The shower head 75 is provided with a solenoid valve A, and a single cold shower valve 79 is provided in the room of the shower room. The air supply component 711 and the exhaust component 712 are arranged diagonally on the top of the shower room, and a plurality of inspection sealing cover plates 713 are provided on the top of the shower room.

[0081] The shower room of the present invention is a shower measure developed according to the requirements of biological laboratories and P3P4 clean workshops; the staff in P3P4 clean workshops, some pharmaceutical companies and biological laboratories must undergo a compulsory shower before they need to leave the work area and change their clothes, so that various harmful substances that may be contaminated on the body can be washed away from the body by showering. In order to achieve the safety of the employees themselves and the safety of the surrounding environment and personnel, since the employees must pass through the shower room when they leave the work area, the shower room is set to automatically spray, so it is called a shower room. The present invention combines and adjusts the air supply component 711 and the exhaust component 712 to form a negative pressure inside the shower room, preventing the air in the shower room from spreading to the outside with the opening and closing of the door. When the staff enters the work area from the work preparation area, they need to pass through the human flow channel next to the shower room. This channel is realized as a one-way passage by electromagnetic interlocking, and only personnel can enter. When the staff exits the work area, they must pass through the shower room and take a shower for a certain period of time before they can exit. The staff is forced to take a shower to achieve the purpose of removing the viruses carried by the staff in the dangerous work area and prevent the virus from flowing out of the work area. Infection occurs.

[0082] When the staff presses the door opening button at the shower room door, the electromagnetic lock A72 of the entry door 71 loses power. When the entry door 71 is closed, the electromagnetic lock A72 is energized and tightly locked. The staff pushes the entry door to enter the shower area. Before this step, the shower temperature and shower time can be edited through the human-machine interface. This time must not be lower than the minimum required time of the system. After entering the shower room, wait for a few seconds, and the system will automatically spray. During this process, if the water temperature is abnormal due to mechanical or electrical failure, the shower staff can manually adjust the water temperature through the single-cold concealed shower valve to reach the desired temperature.

[0083] When the shower time is up, the electromagnetic lock B of the push-out door 77 loses power, and the person exits from the push-out door 77, reaches the work preparation area, and leaves normally. The door panels of the entry door 71 and the push-out door 77 are concealed with sealing strips, which fit tightly with the door frame, so that when spraying, water will not flow out from the door gap, but flow into the sewage collector 710 at the bottom and enter the centralized treatment system uniformly to prevent the leakage of viruses. The present invention is provided with an air supply port and an air exhaust port, and by adjusting the air volume to reach a certain negative pressure value of about -5Pa to -10Pa, it is ensured that there is always good fresh air circulation in the shower room, making people feel comfortable.
