Portable negative-pressure medical/dental procedures and isolation chamber
View Patent ↗A portable negative air pressure apparatus for isolating a treatment subject to permit a selected treatment procedure to be performed by a treatment operator. The apparatus comprises an air source connected to a closed chamber for sealable disposition over the head, neck and upper thorax of the treatment subject with the chamber having air ports, in and out. The chamber has rigid clear sides and a plurality of sealed ports, with the ports including sealed armholes for access, and with sealed gloves connected to the sealed armholes. The chamber also has at least one instrument hatch to permit introduction into the chamber of instruments for carrying-out the selected treatment procedure.
1. A portable negative air pressure apparatus for isolating a treatment subject to permit a selected treatment procedure to be performed by a treatment operator thereon, said apparatus comprising:
an air source having an air source in and an air source out;
a closed chamber connected to said air source, said chamber having a port connected to said air source in and a second air source port connected to said air source out, said chamber is formed from a rigid clear polymeric material;
said chamber adapted for sealable disposition over the head, neck and upper thorax of the treatment subject, and said chamber having a plurality of sealed ports;
said ports including sealed armholes for access thereinto, and with sealed gloves connected to said sealed armholes; and
said chamber further including at least one instrument hatch to permit introduction into the chamber of instruments for carrying out the selected treatment procedure.
2. The portable negative air pressure apparatus of claim 1 wherein said polymeric material is polycarbonate.
3. The portable negative air pressure apparatus of claim 1 wherein said polymeric material comprises acrylic polymers.
4. The portable negative air pressure apparatus of claim 1 wherein said chamber comprises a rigid front wall, back wall, two side walls and a top wall joined together at the edges thereof.
5. The portable negative air pressure apparatus of claim 4 wherein said rigid front wall, two side walls and said top wall have one or more sealed armholes for gloved access into said chamber.
6. The portable negative air pressure apparatus of claim 4 wherein each of said rigid front wall, two side walls and said top wall have two sealed armholes for gloved access into said chamber.
7. The portable negative air pressure apparatus of claim 4 wherein said rigid side walls have at least one hose port disposed therein for access of a treatment hose into said chamber.
8. The portable negative air pressure apparatus of claim 4 wherein said rigid side walls have a curved contoured surface at a proximal portion thereof for mateable engagement with a shoulder of the treatment subject.
9. The portable negative air pressure apparatus of claim 4 wherein said rigid front wall has a lower surface for mateable engagement with an upper portion of the chest of the treatment subject.
10. The portable negative air pressure apparatus of claim 1 further comprising a disposable polymeric covering for the head, neck and upper thorax of the treatment subject when undergoing the selected treatment procedure.
11. The portable negative air pressure apparatus of claim 10 , wherein said disposable polymeric covering includes at least one access opening thereinto to permit access only to the portion of the treatment subject undergoing the selected treatment procedure.
12. The portable negative air pressure apparatus of claim 10 , wherein said disposable polymeric covering includes margins sealable under the rigid front wall and side walls of said chamber.
13. The portable negative air pressure apparatus of claim 1 wherein the air source is a High Efficiency Particulate Air (HEPA) source.
