Abstract
An air purification and disinfection system includes an apparatus having a housing, an ultraviolet disinfection chamber, an air mover, and an air distribution unit in communication with the disinfection chamber. Air is passed through the disinfection chamber where it is purified and disinfected before it is delivered to the user of the apparatus through the air distribution unit. The apparatus can be configured as an open or a closed circuit system. The system may be configured to purify air in an airplane, a conference room, a classroom, or as a portable unit for an individual user. As a portable unit the disinfection chamber can be incorporated into a back pack, a vest, a purse, a briefcase, a shoulder bag, a cervical collar, or any other format for being carried by the user.
Claims37
A personal air purification and disinfection system comprising:
- (a) a housing having a housing inlet and a housing outlet, wherein the housing is opaque to UV-C light;
- (b) a pump in communication with the housing inlet and housing outlet, wherein the pump is configured to increase or decrease a rate of air flow in the housing;
- (c) an inner box containing multiple disinfection chambers embedded within the housing, each chamber containing a plurality of UV-C light sources, an air inlet and an air outlet;
- (d) a housing airflow pathway going from the housing inlet, winding through each of the multiple disinfection chambers from their air inlets to their air outlets, and exiting the housing through the housing outlet, wherein the air moves in a serpentine pathway as it moves from a first disinfection chamber to a second disinfection chamber;
- (e) a helical airflow diverter within each disinfection chamber, wherein the helical airflow diverter creates a helical path for the airflow pathway as the airflow pathway proceeds from the air inlet to the air outlet of each disinfection chamber;
- and
- (f) an air distribution unit in fluidic communication with the housing outlet and the housing inlet, wherein the air distribution unit comprises an airtight, sealable and transparent full face or a half face mask, and wherein the face mask delivers purified and disinfected air to a user of the system.
A personal air purification and disinfection system comprising:
- (a) a housing having a housing inlet and a housing outlet, wherein the housing is opaque to UV-C light;
- (b) a pump in communication with the housing inlet and housing outlet, wherein the pump is configured to increase or decrease a rate of airflow in the housing;
- (c) an inner box containing multiple disinfection chambers embedded within the housing, each chamber containing a plurality of UV-C light sources, an air inlet and an air outlet;
- (d) a housing airflow pathway going from the housing inlet, winding through each of the multiple disinfection chambers from their air inlets to their air outlets, and exiting the housing through the housing outlet, wherein the air moves in a serpentine pathway as it moves from a first disinfection chamber to a second disinfection chamber;
- (e) a helical airflow diverter within each disinfection chamber, wherein the helical airflow diverter creates a helical path for the airflow pathway as the airflow pathway proceeds from the air inlet to the air outlet of each disinfection chamber;
- and
- (f) an air distribution unit in fluidic communication with the housing outlet and the housing inlet, wherein the air distribution unit comprises an endotracheal tube in fluidic communication with a ventilator.
