Abstract

<P>PROBLEM TO BE SOLVED: To solve the problems that, at present, many japanese people go out overseas and many foreigners visit Japan in the internationalized society, there are so many unsolved problems such as unknown infectious diseases, the country is almost in a defenseless condition when a patient having strongly infectious disease is carried in present circumstances, hospitals equipped with perfect isolation facilities for inpatients such as a low pressure room are few in the country, and inpatient isolation at general hospitals or facilities is extremely difficult. <P>SOLUTION: When the patient having strongly infectious disease is carried, by setting a patient accommodation space on a stretcher and bringing the patient accommodation space into negative pressure state by the negative pressure apparatus with ozone generator, bacteria are not leaked outside. Even in a fixed bed, by providing a patient accommodation space and bringing the patient accommodation space into negative pressure state by the negative pressure apparatus with ozone generator, bacteria are not leaked outside. By bringing the inside of a room of a hospital etc. into a negative pressure state by the negative pressure apparatus with ozone generator, bacteria are not leaked outside to prevent other people from infection. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention is a sealed fixed and movable bed and a negative pressure device with an ozone generator in the room. When a patient is transported or hospitalized, bacteria held by the patient leak to the outside of the bed or hospital room, and other people. A negative pressure device with an ozone generator, which has a structure that does not infect the body.

  When a highly contagious disease occurs in a conventional transfer mobile bed and a patient is transported, it is mainly placed in a storage bag with a zipper that can be sealed or covered with a sheet to disinfect.

  However, this method cannot completely prevent the patient from being completely isolated and spreading the bacteria to the outside.

  Currently, stretchers that completely isolate and transport patients are being developed and used, but they are very expensive and generally not popular.

  A stretcher or the like currently used is not equipped with a device that can be completely sterilized, such as ozone sterilization treatment, and cannot sterilize the patient accommodation space.

  Even in the case of isolation in the hospital, it is extremely difficult to isolate a highly contagious patient in a hospital without facilities such as a low-pressure room.

  Moreover, although it ventilates with a ventilation fan etc. as a means to eliminate the malodor etc. of an animal stable, a toilet, etc., malodor and bacteria etc. are discharged | emitted randomly to the open air.

  The above-mentioned conventional stretchers and hospital and hospital beds that transport patients not only cannot completely isolate patients but also have functions that prevent and sterilize bacteria and are extremely dangerous. ing.

  In animal stables and toilets, malodors and bacteria are randomly released into the open air.

  The present invention prevents the infection of other people in such infectious patient transportation and hospitalization in such a conventional dangerous state, and releases to the outside air such as malodorous bacteria. The purpose is prevention.

  In order to achieve the above object, the present invention is a negative pressure device with an ozone generator in a patient-accommodating space of a hermetically fixed and moving bed, and accommodates a tent-like or capsule-like patient in which the patient is accommodated by the suction force of a fan A negative pressure device with an ozone generator that prevents the bacteria held by the patient from going out of the patient storage space by creating a negative pressure in the space. The ozone reaction chamber draws air sucked from the patient storage space by the suction force of the fan. Ozone generation, which is filtered through a filter such as hepa or ulpa, sterilizes bacteria attached to the filter with ozone, exhausts ozone with a catalyst such as honeycomb activated carbon, and releases sterilized air to the outside Negative pressure device with device.

  A negative pressure device with an ozone generator that creates negative pressure in the room, such as a hospital room, using the suction force of the fan, and does not let the bacteria held by the patient out of the room, such as the patient room, where the patient is housed. Air sucked from the housed room by the suction force of the fan is sent to the ozone reaction chamber, filtered with a filter such as hepa or ulpa, and bacteria adhering to the filter are sterilized with ozone, and a catalyst such as honeycomb activated carbon is used. A negative pressure device with an ozone generator that discharges sterilized air after exhausted ozone treatment.

  The tent-like and capsule-like patient storage space of the sealed fixed and moving bed and the room inside the room such as the hospital room are circulated while negative pressure is sterilized to sterilize the tent-like and capsule patient space and the room such as the hospital room. A negative pressure device with an ozone generator.

  A negative pressure device with an ozone generator that sterilizes and sterilizes ozone by circulating ozone in spaces with bad odors such as animal stables and toilets, and sucks the air in the space with the suction of a fan.

A negative pressure device with an ozone generator that discharges to the outside.

  As described above, the negative pressure device with an ozone generator according to the present invention can completely isolate a patient and further reduce the contamination of the outside air.

  When a patient is being transported, it can be installed on a stretcher or other mobile stretcher and housed in a hospital or other facility, so it can be installed separately from a stretcher or other mobile stretcher. Patients can be accommodated with peace of mind.

  It is a negative pressure device with an ozone generator that can be used in general hospitals and facilities because it is extremely low cost and has little economic burden.

BEST MODE FOR CARRYING OUT THE INVENTION

  Hereinafter, an embodiment of the present invention will be described with reference to FIG.

  In FIG. 1, air in which bacteria such as a patient accommodation space and a room float is sucked by a fan 3 from an inlet 2 and is divided into exhaust and circulation by a branch duct 4. The exhaust passes through the exhaust duct 5 and is exhausted by ozone reaction. Reaction sterilization with ozone generated from the exhaust ozone generator 6 in the chamber 8 and bacteria attached to the filter 11 are sterilized with ozone.

  The sterilized air containing ozone is exhausted by the catalyst 12 and exhausted to the outside through the exhaust port 13 by exhausting the sterilized and odorless air to the negative pressure in the patient accommodating space and the room. Leakage of bacteria and the like from the room can be prevented.

  The negative pressure in the patient accommodation space and the room can be adjusted by the negative pressure adjusting valve 9.

  The branch duct 4 is divided into exhaust and circulation. The circulation passes through the circulation duct 16 and is sterilized by reaction with ozone generated from the circulation ozone generator 14 in the circulation ozone reaction chamber 17. Further, the bacteria attached to the filter 20 are sterilized with ozone. It is processed.

  The sterilized air containing ozone returns from the circulation ozone discharge port 21 to the intake port 2 through the patient accommodation space or the room and repeats circulation.

  Thereby, sterilization and deodorization of the patient accommodation space and the room is performed, and the patient accommodation space and the room can be made sterile.

  The circulation air volume can be adjusted by the circulation air volume adjustment valve 19.

  The air of the odorous space such as animal stables and toilets and the space where germs float is sucked by the fan 3 from the air inlet 2, branched by the branch duct 4, passed through the circulation duct 16 and in the circulation ozone reaction chamber 17. In response to the ozone generated from the circulating ozone generator 14, it is sterilized and deodorized, and the bacteria attached to the filter 20 are sterilized with ozone.

  The sterilized and odorless air containing ozone is discharged from the circulation ozone discharge port 21 to a space such as an animal stable or a toilet.

  In the ventilation of animal stables and toilets, the air is sucked by the fan 3 through the air inlet 2 and passes through the exhaust duct 5 and reacts with ozone generated from the exhaust ozone generator 6 in the exhaust ozone reaction chamber 8 to be sterilized and deodorized. Furthermore, the bacteria attached to the filter 11 are sterilized with ozone.

  The air that has been sterilized and deodorized and contains ozone is exhausted with ozone by the catalyst 12, and the sterilized and odorless air is exhausted from the exhaust port 13 to the outside air to ventilate without polluting the outside air.
