Abstract
Abstract An anaerobic specimen collecting and transporting device is described incorporating a transporting tube having a suitable transport media therein; a removable closure is provided for the tube and incorporates a swab slidably mounted therein; the closure is compartmentalized and includes a frangible ampule containing a liquid for combination with a hydrogen generating substance to remove oxygen from within the device that would otherwise be destructive of the collected specimen.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
130 words
An anaerobic specimen collecting and transporting device comprising: a transport tube for enclosing a specimen and maintaining the specimen in a predetermined atmosphere; a compartmentalized closure removably secured to, and sealingly engaging, said tube; a specimen gathering swab slidably mounted in said closure and extending through said closure into said tube; said closure including a first compartment containing a frangible ampule having a liquid therein; a second compartment in said compartmentalized closure communicating with the said first compartment and containing a hydrogen generating substance, said substance, when combined with said liquid, producing hydrogen; and a third compartment in said compartmentalized closure communicating with said second compartment, containing a catalytic material for producing a combinative reaction of hydrogen from said hydrogen generating substance and oxygen in the atmosphere within said device.
Claim 2
Dependent Claim
130 words
An anaerobic specimen collecting and transporting device comprising: a transport tube for enclosing a specimen and maintaining the specimen in a predetermined atmosphere; a compartmentalized closure removably secured to, and sealingly engaging, said tube; a specimen gathering swab slidably mounted in said closure and extending through said closure into said tube; said closure including a first compartment containing a frangible ampule having a liquid therein; a second compartment in said compartmentalized closure communicating with the said first compartment and containing a hydrogen generating substance, said substance, when combined with said liquid, producing hydrogen; and a third compartment in said compartmentalized closure communicating with said second compartment, containing a catalytic material for producing a combinative reaction of hydrogen from said hydrogen generating substance and oxygen in the atmosphere within said device.
Claim 3
Dependent Claim
27 words
The combination as set forth in claim 1 wherein said liquid is water and said hydrogen generating substance is responsive to contact with water and generating hydrogen.
Claim 4
Dependent Claim
20 words
The combination as set forth in claim 1 wherein said liquid is water and said hydrogen generating substance is magnesium.
Claim 5
Dependent Claim
14 words
The combination as set forth in claim 2 wherein said catalytic material is palladium.
Claim 6
Dependent Claim
116 words
An anaerobic specimen collection and transporting device comprising: a transport tube for enclosing a specimen and maintaining the specimen in a predetermined atmosphere; a compartmentalized closure removably secured to, and sealingly engaging, said tube; a specimen gathering swab slidably mounted in said closure and extending through said closure into said tube; said closure including a first compartment containing a frangible ampule having a liquid therein; and a second compartment communicating with said first compartment containing a substance chemically activated by said liquid to remove oxygen from the atmosphere within said device; and said tube including a viscous anaerobic transport media for receiving an end of said swab when the latter is slidably lowered into said tube.
Claim 7
Dependent Claim
116 words
An anaerobic specimen collection and transporting device comprising: a transport tube for enclosing a specimen and maintaining the specimen in a predetermined atmosphere; a compartmentalized closure removably secured to, and sealingly engaging, said tube; a specimen gathering swab slidably mounted in said closure and extending through said closure into said tube; said closure including a first compartment containing a frangible ampule having a liquid therein; and a second compartment communicating with said first compartment containing a substance chemically activated by said liquid to remove oxygen from the atmosphere within said device; and said tube including a viscous anaerobic transport media for receiving an end of said swab when the latter is slidably lowered into said tube.
Claim 8
Dependent Claim
44 words
The combination as set forth in claim 5 including a divider removably mounted between said tube and closure and extending into said tube for receiving said swab and maintaining separation of said swab and said transport media until said device is to be used.
Claim 9
Dependent Claim
25 words
The combination as set forth in claim 5 wherein said liquid contains CuSO4 and H2 SO4 and wherein said chemically activated substance is steel wool.
