Abstract

A portable/disposable decontamination enclosure unit comprising a frame system which includes first and second rectangular end members and at least two pairs of opposing vertical frame members having opposing ends attached to the first and second rectangular end members, the frame system being adapted to be manually extended from a retracted closed position to an extended open position in which position the frame system forms a generally oblong configuration. The extended frame system is enclosed by a length of lay-flat material substantially impermeable to particulate material forming a bag enclosure member, the bag member being flexible and collapsible and closed at one end to form the bottom of the bag, the other end having a rim edge defining an upper opening to receive the frame system, the bag member being sufficiently long to enclose the frame system when extended. The rim edge is sealed whereby the bag member and enclosed extended frame member define a chamber area substantially impermeable to particular material. A resealable port provides access to the chamber area.

Claims

1. A portable decontamination enclosure unit comprising:

a frame system comprising;

(a) first and second opposing end members;

each of said opposing end members comprised of a quadrilateral base member and side walls extending outwardly from said base member which collectively form an open-ended container; and

(b) quadrilaterally disposed frame means comprised of vertically extendable telescoping members each having one end pivotally connected to a side wall of the first end member, and the other end slidably and pivotally connected to the corresponding side wall of the second end member;

said quadrilaterally disposed frame means enabling the opposing first and second end members to be retracted to a closed position whereby said open-ended containers form an enclosure in which a bag member may be carried;

said frame system forming a generally oblong configuration when in the extended position;

a length of lay-flat material substantially impermeable to particulate material forming a bag member;

said bag member being flexible and collapsible;

said bag member being closed at one end, the other end having a rim edge defining an opening to receive said frame system;

said bag member having a sufficient size to enclose said frame system when in the extended position;

sealing means for sealing said rim edge whereby said bag member and enclosed extended frame system define a chamber area substantially impermeable to particulate material; and

resealable means providing access to and egress from said chamber.

2. A portable decontamination enclosure unit according to claim 15 wherein said bag member is formed of a plastic material.

3. A portable decontamination enclosure unit according to claim 15 wherein said plastic material is polyethylene.

4. A portable decontamination enclosure unit according to claim 15 further comprising means for introducing a negative air pressure into said decontamination unit during use.

5. A portable decontamination enclosure unit according to claim 15 wherein said rim edge enables removal of said frame system from said bag member when the enclosure unit has received hazardous material whereby said bag member may be collapsed and sealed for disposal.
