Abstract
Abstract A kit and method for its use for containing potentially infectious devices. The potentially infectious devices are deposited in a container to which is added a cyanoacrylate ester monomer-containing composition to at least partially envelope the potentially infectious devices. The cyanoacrylate ester monomer-containing composition is caused to harden through polymerization of the cyanoacrylate ester monomer to immobilize the devices.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
63 words
A method for containing potentially infectious devices comprising: A. depositing said potentially infectious devices in a container; B. adding to said container a sufficient quantity of a cyanoacrylate ester monomer-containing composition to at least partially envelope said potentially infectious devices; and C. causing said cyanoacrylate ester monomer-containing composition to harden through polymerization of said cyanoacrylate ester monomer to immobilize said potentially infectious devices.
Claim 2
Independent Claim
63 words
A method for containing potentially infectious devices comprising: A. depositing said potentially infectious devices in a container; B. adding to said container a sufficient quantity of a cyanoacrylate ester monomer-containing composition to at least partially envelope said potentially infectious devices; and C. causing said cyanoacrylate ester monomer-containing composition to harden through polymerization of said cyanoacrylate ester monomer to immobilize said potentially infectious devices.
Claim 3
Dependent Claim
21 words
The method of claim 1 further comprising the addition of a catalyst to promote the polymerization of said cyanoacrylate ester monomer.
Claim 4
Dependent Claim
31 words
The method of claim 2 wherein said catalyst is coated on one or more of the inner wall of said container prior to the deposit of the potentially infectious devices therein.
Claim 5
Dependent Claim
53 words
The method of claim 1 wherein said composition further comprises: A. approximately 2 to 10,000 ppm of a stabilizer for the cyanoacrylate ester monomer; B. approximately 2 to 5000 pm of an inhibitor for the cyanoacrylate ester monomer; and C. approximately 5 to 70% (wt.) of a plasticizer for the cyanoacrylate ester monomer.
Claim 6
Dependent Claim
41 words
The method of claim 4 wherein said composition further comprises a viscosity enhancer resulting in a viscosity of the composition to be approximately 0 to 1000 cps when measured on a Brookfield viscometer at 20 rpm with a number 4 spindle.
Claim 7
Dependent Claim
43 words
The method of claim 2 wherein said catalyst is present in an amount between approximately .00001 to 5% by volume based upon the volume of the container, said catalyst comprising a member selected from the group consisting of primary, secondary and tertiary amines.
Claim 8
Dependent Claim
11 words
The method of claim 4 wherein said stabilizer comprises a hydroquinone.
Claim 9
Dependent Claim
35 words
The method of claim 4 wherein said inhibitor is of the Lewis acid type comprising a member selected from the group consisting of SO 2 , NO 2 , CO 2 and BF 3 etherate.
Claim 10
Dependent Claim
23 words
The method of claim 4 wherein said plasticizer comprises a member selected from the group consisting of dibutylphthalate, dioctylphthalate, diisononylphthalate, dioctyladipate and triacetin.
Claim 11
Dependent Claim
25 words
The method of claim 1 wherein said cyanoacrylate ester monomer-containing composition upon hardening substantially encapsulates, anchors and precipitates said potentially infectious devices within said container.
Claim 12
Dependent Claim
49 words
A kit for containing partially infectious devices comprising a container for holding said potentially infectious devices and a sufficient quantity of a cyanoacrylate ester monomer-containing composition to be supplied to said container in an amount to at least partially envelope said potentially infectious devices when added to said container.
Claim 13
Dependent Claim
49 words
A kit for containing partially infectious devices comprising a container for holding said potentially infectious devices and a sufficient quantity of a cyanoacrylate ester monomer-containing composition to be supplied to said container in an amount to at least partially envelope said potentially infectious devices when added to said container.
Claim 14
Dependent Claim
18 words
The kit of claim 11 further comprising a catalyst to promote the polymerization of said cyanoacrylate ester monomer.
Claim 15
Dependent Claim
31 words
The kit of claim 12 wherein said catalyst is coated on one or more of the inner walls of said container prior to the deposit of the potentially infectious devices therein.
Claim 16
Dependent Claim
53 words
The kit of claim 11 wherein said composition further comprises: A. approximately 2 to 10,000 ppm of a stabilizer for the cyanoacrylate ester monomer; B. approximately 2 to 5000 pm of an inhibitor for the cyanoacrylate ester monomer; and C. approximately 5 to 70% (wt.) of a plasticizer for the cyanoacrylate ester monomer.
Claim 17
Dependent Claim
41 words
The kit of claim 14 wherein said composition further comprises a viscosity enhancer resulting in a viscosity of the composition to be approximately 0 to 1000 cps when measured on a Brookfield viscometer at 20 rpm with a number 4 spindle.
Claim 18
Dependent Claim
43 words
The kit of claim 12 wherein said catalyst is present in an amount between approximately .00001 to 5% by volume based upon the volume of the container, said catalyst comprising a member selected from the group consisting of primary, secondary and tertiary amines.
Claim 19
Dependent Claim
11 words
