[Detailed description of the invention]

[0001]

TECHNICAL FIELD The present invention relates to a novel sterile bed device used in hospitals and the like to sterilize biological particles.

[0002]

[Prior Art] A so-called biological clean room is required in hospitals for patients to undergo hospital treatment, and the space housing the bed used by the patient is sterile so that biological particles such as bacteria and viruses are not present. It is necessary to

[0003] In typical prior art, such biological clean rooms partition the inside of a building with panels or the like to form a clean space. With such prior art, it is difficult to change the degree of cleanliness, and therefore the desired cleanliness cannot be easily obtained. Furthermore, with this prior art, when fumigating using formalin or the like, it is almost impossible to use the entire clean room and its vicinity.

[0004] In another prior art, a clean room device that supplies clean air to a space containing a bed is integrally configured, and wheels are provided so that the clean room device can be moved within the hospital.

[0005]

Problems to be Solved by the Invention Such a movable clean room apparatus has a small overall structure so that it can pass through the hallways and entrances and exits of each room in the hospital. Therefore, living conditions are poor, which is a big problem, especially for patients who have to undergo long-term medical treatment for many months.

[0006] The purpose of the present invention is to easily change the cleanliness of the space where the bed is stored to a desired value, and to easily perform cleaning using formalin fumigation, etc., and to improve livability. It is an object of the present invention to provide a sterile bed device that can improve the quality of a sterile bed.

[0007]

[Means for Solving the Problems] The present invention provides a bed room unit which is generally a rectangular parallelepiped, has a bed storage space for storing a bed, and has open ends communicating with the bed storage space on at least two side walls. a clean air supply source that is removable from at least one open end of the bedroom unit and supplies clean air to the open end; or an auxiliary unit that forms a space that communicates with the bed storage space, and the bed room unit is provided with a sterile gas supply connection port and an exhaust connection port for adjusting internal pressure, and the sterile gas is supplied from the former to form a space that communicates with the bed storage space. While sterilizing the inside, controlling the exhaust volume so that the inside of the bed room is always under negative pressure through the latter, and discharging the sterile gas to the exhaust line through a means to detoxify it, allows the sterile gas to be released outside the bed. This is a sterile bed device characterized by eliminating leakage of sterile gas.

[0008] The present invention is also characterized in that a part of the gas from the exhaust line is guided to the detoxifying means, and the remaining gas is returned to the sterilizing gas supply connection port.

[0009] Furthermore, the present invention is characterized in that the sterilizing gas is ozone.

[0010]

[Operation] According to the present invention, a clean air supply source is attached to one of the open ends formed in at least two side walls of the bedroom unit, which is roughly a rectangular parallelepiped, and an auxiliary unit is attached to the other open end. Installing. Therefore, the desired degree of cleanliness can be easily changed by replacing clean air supply sources with different degrees of cleanliness, and the bedroom unit and auxiliary unit can be used in common. It's convenient to be able to do it.

[0011] Furthermore, when cleaning a bedroom unit etc. by fumigating with formalin, it is only necessary to replace the bedroom unit, and the patient can be treated with a new bedroom unit. , easy to clean.

[0012] Furthermore, according to the present invention, the bedroom unit, the clean air supply source, and the auxiliary unit can be separated and moved to hallways and entrances of buildings such as hospitals. Therefore, the bedroom unit, the clean air supply and the auxiliary unit can be made as large as possible, and in particular the bedroom unit and the auxiliary unit can be made large to provide good living comfort, which is especially useful in long-term care. Sometimes preferred.

[0013] The bedroom unit and the auxiliary unit are provided with a connection port for supplying a sterilizing gas such as ozone, and an exhaust connection port for adjusting internal pressure. Sterilizing gas such as ozone can be supplied from the supply connection port to disinfect the inside of the bedroom unit and the auxiliary unit. In addition, the amount of exhaust air is adjusted so that the inside of the bedroom unit and the auxiliary unit always have a negative pressure through the exhaust connection port for adjusting internal pressure, thereby preventing ozone from leaking to the outside. A deozonizer, which is a detoxification means, is installed in the exhaust line of the gas discharged from the exhaust connection port for internal pressure adjustment, and a part of the sterilizing gas, such as ozone, is converted into oxygen and rendered harmless, and the detoxified gas is released into the atmosphere. It is dissipated and discharged. This makes it easy to disinfect the inside of the bedroom unit and auxiliary units.
There is no need for fumigation using formalin or the like as described in connection with the prior art, and it can be used immediately after disinfection. A portion of the remainder from the exhaust line is returned to the supply connection via an ozonizer or directly.
