Description

RELATED APPLICATIONS

The present invention is a continuation of, was first described in, and claims the benefit of Foreign Application No. CN112237521A/201010806611, filed Oct. 11, 2020, the entire disclosures of which are incorporated herein by reference.

FIELD OF THE INVENTION

The present invention relates generally to a medical isolation facility to restrict air born disease.

BACKGROUND OF THE INVENTION

The existing such facilities are mainly negative pressure isolation wards which are built in the hospital building. However, the existing negative pressure isolation ward has obvious defects in the following aspects:

It has no flexibility to deal with the fast coming and going of air born disease like SARS or COVID 19. The existing negative pressure isolation ward is normally built in the traditional building. When COVID 19 comes suddenly, the amount of the wards won't be enough. Once COVID 19 has gone, the amount of the wards will be too much for a normal hospital to keep.

It has no flexibility to deal with the fast moving of air born disease like SARS or COVID 19. Once the COVID 19 moves to other cities or countries, the existing negative pressure wards will be demolished, and new negative pressure wards need to be built in other places.

It has no flexibility to change the function to other kind of facilities. For instance, it cannot be changed into a hotel room when the COVID 19 has gone. Or, when the COVID 19 comes back again, a hotel room won't be able to be changed into a negative pressure ward.

The cleaning standard of existing negative pressure ward needs to be updated, since the walls are not washable and there are too many unreachable places between the furniture and the walls.

The HVAC system of existing negative pressure wards needs to be improved, since the central air returning system will bring infectious air to other wards or it will consume too much energy if the central returning system is shut down.

The sewage system of existing negative pressure wards needs to be improved, since the infectious sewage will travel through pipes in other wards in the existing system.

SUMMARY OF THE INVENTION

The In order to overcome the defects of the existing facilities, the invention provides an assembling chamber to contain the content of a typical negative pressure ward. The chamber is independent from the build and can be moved in and out. The framework of the building can carry more or less chambers so that the capacity of the build is changeable. The chamber can be disassembled into standard parts so that it can be transported. It can be also transformed so that it can change the function. The chamber will build the furniture in the walls so that there will be no gape s between furniture and walls. The HVAC system of the chamber has inner air returning system so that the infectious air won't go to other wards. The sewage system of the chamber contains independent water treatment system so that the infectious sewage will infectious sewage will be treated before it arrives in the public pipe system. be treated before it arrives in the public pipe system.

More detailed description is as follows: The chamber is a hexahedral one. one. It comprises a comprises a patient room, a, a doctor buffer room and a buffer room and a patient toilet. The patient room opens a first outer door to the opens a first outer door to the patient (soiled) corridor and the doctor buffer room opens a second outer door to the buffer room opens a second outer door to the staff (clean) corridor. The patient room opens the first inner door the first inner door to the patient toilet and the second inner door to the staff to the patient toilet and the second inner door to the staff buffer door. The second outer door and the he second outer door and the second inner door in the buffer room have second inner door in the buffer room have interlocking function and emergency unlocking function, inter locking function and emergency unlocking function.

The patient room has an observation an observation window, which cannot be opened and a transfer window, which is a box with interlocking and a transfer window, which is a box with interlocking internal and external doors, internal and external doors, to the direction of the staff corridor. The daylighting window is to the direction of the patient corridor. The patient room will contain to the direction of the patient corridor. The patient room will contain one or more one or more wheeled beds and the medical gas devices. The buffer room is provided with closets for clean and for clean and soiled things.

What is also provided in this room is a doctor's hand washing device with a doctor's hand washing device with an automatic induction faucet. The toilet is provided with a patient's hand washing device, a toilet is provided with a patient's hand washing device, a toilet, a shower and a toilet, a shower and a soiled cabinet. The toilet also has a transfer window with interlocking with interlocking doors to the direction of the patient corridor. The HVAC will create the negative pressure The HVAC will create the negative pressure environment exactly as a normal negative pressure ward's HVAC will do. environment exactly as a normal negative pressure ward's HVAC will do.

When the patient room long enough to enough to place three or more three or more wheeled beds, beds, a storage room may be added between the buffer room and the toilet, the storage room is a room for patients between the buffer room and the toilet, the storage room is a room for patients to store personal belongings.

The chamber is made of light and solid materials. All surrounding walls have double shells. All surrounding walls have double shells. There are also spaces in There are also spaces in ceiling and flooring structure. The ceiling and flooring structure. The pipelines and equipment are laid pipelines and equipment are laid in the spaces. And sound insulation and thermal insulation materials are filled in and thermal insulation materials are filled in. All systems in the chamber can be connected to the public system in the building through outlets. in the chamber can be connected to the public system in the building through outlets.

The patient corridor will be raised to the level of the patient room with the framework will be raised to the level of the patient room with the framework structure. structure. The main pipeline of the building system is laid under the building.

The chamber will be manufactured in the factory and then transported to the construction and then transported to the construction site. Once the chamber arrives at the site, it will be lifted to the level of the floor that it will be chamber arrives at the site, it will be lifted to the level of the floor that it will be installed and moved into the building. Only then, installed and moved into the building. Only then, the external wall and the raised corridor will be installed.

The chamber can be transformed by switching the position of the n of the first outdoor and the first outdoor and the second outdoor parts, each of which, each of which is identical for both the shape and the assembling is identical for both the shape and the assembling structure. By doing this, the chamber can be transformed into hotel room or so on since it the chamber can be transformed into hotel room or so on since it will has only one door facing one corridor as will has only one door facing one corridor as a normal hotel room or apartment.

For the chamber with storage room, storage room, the wall between the patient room and the storage is the wall between the patient room and the storage is removeable. By removing the wall, the storage can be transformed into a bar for hotel room or apartment.

The framework of the hospital building should leave certain amount of spare space for a sky garden or other decoration. Once the pandemic comes, the spare space will be filled with more chambers.

The hospital should be associated with a hotel or apartment building. Once the pandemic comes the hospital should be associated with a hotel or apartment building. Once the pandemic comes the hotel or apartment building can be transformed into negative pressure isolation building.

The chamber uses washable materials for the shell and integrated all furniture with the walls, so that the cleaning standard of the chamber will be updated and easily maintained.

The HVAC system in chamber contains an inner air returning pipe system with fan, so that the infectious air will be either exhausted or sucked into the inner returning system and will never infectious air will be either exhausted or sucked into the inner returning system and will never go to other chambers. go to other chambers.

The chamber will have a micro water treatment machine under the raised floor so that the sewage will be treated immediately after it is flushed—before it arrives in the public pipe system.
