Description

Self-quarantine system equipped with air purifying negative pressure function and sterilizing device}

The present invention relates to a self-isolation system equipped with an air purifying negative pressure function and a sterilizing device. More specifically, it is installed in a general house or apartment and is equipped with a toilet in response to the isolation patient directly or the guardian operating the residential ventilation system. By filtering the air inside the sealed patient isolation room and discharging it into the atmosphere or filtering the outside air and flowing it into the patient isolation room, the patient isolation room can be maintained in a negative or positive pressure state, and the inside of the patient isolation room can be maintained in a negative or positive pressure state. By configuring it to allow the patient's food and medication to be brought in and out as a patient isolation measure while maintaining the This is about a self-isolation system equipped with an air purifying negative pressure function and a sterilizing device that prevents the spread of this disease and also allows patients who are sensitive to air pollution to live safely.

Recently, as various infectious diseases such as coronavirus infection-19 (COVID-19) have spread, interest in negative pressure isolation rooms that can isolate and treat patients infected with these infectious diseases is increasing.

The negative pressure isolation room is a special room for housing and treating patients separately from outside and general patients for reasons such as preventing the spread of infectious diseases.

Negative pressure isolation rooms maintain the air pressure in the room lower than atmospheric pressure to prevent pathogens contained in the air, aerosols, or droplets in the room from being discharged to the outside.

In addition, the air in the hospital room is exhausted to the outside through an exhaust facility equipped with a HEPA (highly efficient particular air filter) filter to prevent pathogens from passing through.

These negative pressure isolation rooms require enormous costs and time to install, making it difficult for each hospital to install a negative pressure isolation room.

In addition, in cases where the speed of transmission is fast, such as with coronavirus infection-19, the number of negative pressure isolation rooms is insufficient compared to the number of infected patients, so there are cases where infected patients have to be quarantined at home.

To this end, if the negative pressure isolation ward installed in the hospital is insufficient, it can be easily installed outside, can be installed as a single room per person to avoid the risk of further spread within the ward, and the demand for negative pressure ward containers that can be moved as needed is increasing.

The indoor air flowing into the second space (1110b) flows in through the positive pressure air flow opening (1142a) of the open positive pressure air flow induction box (1142) and then flows into the atmosphere through the second pipe (12). is discharged.

As described above, the indoor air in the patient isolation room (A) where the patient is isolated is safely filtered by the HEPA filter (1120) and discharged into the atmosphere, so it is possible to prevent the spread of contaminants by the isolated patient to his or her housemates. .

At this time, when the front opening/closing door 132 of the pass box 130 installed on the load-bearing wall (D) is opened and closed in order to provide medicine along with food to the patient isolated in the patient isolation room (A), the front door detection sensor The unit 134 detects this and applies the detected signal to the control unit.

As a result, the front and rear doors 132 and 132' are each maintained in a locked state for 20 seconds by the front and rear door lock members 135 and 135', which are driven in response to the control of the control unit.

As described above, while the front and rear doors 132 and 132' remain locked for 20 seconds, food and medicine provided to the housing 131 are sterilized by the UV lamp 136.

Conversely, even when a patient isolated in the patient isolation room (A) wishes to take out the provided food bowl, each door is kept locked for 20 seconds by opening and closing the rear opening/closing door (132'), so that the patient isolation room (A) A) Pollutants inside will not leak out to the outside, that is, the living room.

Meanwhile, when a patient sensitive to air pollution enters the patient isolation room and uses the patient isolation room, a self-isolation system equipped with a patient isolation room (A), an air purifying negative pressure function, and a sterilizing device while driving the negative pressure drive unit 1130 While sterilizing and disinfecting (100), the HEPA filter (1120) is replaced.

Afterwards, press the positive pressure operation button on the control panel.

By pressing the positive pressure operation button, the positive pressure driving motor of the positive pressure driving unit 1140 installed in the second space 1110b of the positive and negative pressure housing 1110 is driven.

At the same time as the positive pressure driving motor of the positive pressure driving part 1140 is driven, the negative pressure air flow driving part 1133 of the negative pressure driving part 1130 is driven under the control of the control unit.

By driving the negative pressure air flow driver 1133, the negative pressure air flow opening/closing damper 1134 rotates, thereby opening the negative pressure air flow opening 1132a of the negative pressure air flow induction box 1132.

Meanwhile, the positive pressure driving fan 1141 is driven by driving the positive pressure driving motor, and as a result, external air flows into the second space 1110b and then passes through the replaced HEPA filter into the first space. It flows to unit 1110a.

The external air flowing into the first space 1110a is introduced through the negative pressure air flow opening 1132a and then blown into the patient isolation room A through the first pipe 11.

Therefore, the patient isolation room (A) can be kept clean, so even patients who are sensitive to air pollution can live safely in the patient isolation room.
