Methods and systems for decontaminating harmful material
View Patent ↗Decontaminating access structures that allow the partial insertion of decontamination tools into glove boxes and the like to easily and safely decontaminate harmful materials are provided.
1. A glove box configured to enclose harmful material, the glove box comprising: a decontaminating access structure, the decontaminating access structure comprising;
a pressure-activated latch mechanism;
a rotatable hinge; a rotatable hatch; wherein the hinge is operable to rotate the entire rotatable hatch to insure that the rotatable hatch is in an open or closed position, wherein the hinge and latch mechanism function to securably close the hatch in the closed position;
an outer, hollow frame; a first circumferential sealing means; wherein the outer hollow frame is configured to receive the first circumferential sealing means around a circumferential surface of the frame;
an inner hollow frame;
wherein the hatch, hinge, latch, outer frame, inner frame and first circumferential sealing means are operable to form a first seal to prevent harmful material from escaping the inside of the glove box that encloses the harmful material and to prevent material from the outside from entering the glove box when the hatch is in a closed position;
a displaceable cover; a cover circumferential sealing means; wherein the displaceable cover is operable to receive the cover circumferential sealing means around a circumferential surface of the cover, wherein the cover and cover sealing means are operable to form a second seal to prevent harmful material from escaping the inside of the glove box and for preventing material from the outside from entering the glove box when the cover is in a closed position.
2. The glove box as in claim 1 wherein the latch comprises a second circumferential sealing means for preventing harmful material from escaping the inside of the glove box and for preventing material from entering the glove box from outside the glove box.
3. The glove box as in claim 1 wherein the decontaminating access structure may further comprise a bezel for securing a flexible, protective sleeve between the bezel and the inner hollow frame.
4. The glove box as in claim 1 wherein the decontaminating access structure is configured to allow partial insertion of a decontamination tool for substantially decontaminating the harmful material inside the glove box configured to enclose the harmful material.
5. A decontaminating access structure for a glove box comprising:
a pressure-activated latch mechanism;
a rotatable hinge; a rotatable hatch; wherein the hinge is operable to rotate the entire rotatable hatch to insure that the rotatable hatch is in an open or closed position, wherein the hinge and latch mechanism function to securably close the hatch in the closed position;
an outer, hollow frame; a first circumferential sealing means; wherein the outer hollow frame is configured to receive the first circumferential sealing means around a circumferential surface of the frame;
an inner hollow frame;
wherein the hatch, hinge, latch, outer frame, inner frame and first circumferential sealing means are operable to form a first seal to prevent harmful material from escaping inside of a glove box that encloses harmful material and to prevent material from the outside from entering the glove box that encloses the harmful material when the hatch is in a closed position;
a displaceable cover; a cover circumferential sealing means; wherein the displaceable cover is operable to receive the cover circumferential sealing means around a circumferential surface of the cover, wherein the cover and cover sealing means are operable to form a second seal to prevent harmful material from escaping the inside of the glove box that encloses the harmful material and for preventing material from the outside from entering the glove box that encloses the harmful material when the cover is in a closed position.
6. The structure as in claim 5 wherein the latch comprises a second circumferential sealing means for preventing harmful material from escaping the inside of the glove box that encloses the harmful material and for preventing material from entering the glove box that encloses the harmful material from the outside.
7. The structure as in claim 5 further comprising a bezel for securing a flexible, protective sleeve between the bezel and the inner hollow frame.
8. The structure as in claim 5 configured to allow partial insertion of a decontamination tool for substantially decontaminating the harmful material inside the glove box configured to enclose the harmful material.
