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

1. 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.

2. The method of claim 1 further comprising the addition of a catalyst to promote the polymerization of said cyanoacrylate ester monomer.

3. 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.

4. 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.

5. 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.

6. 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.

7. The method of claim 4 wherein said stabilizer comprises a hydroquinone.

8. The method of claim 4 wherein said inhibitor is of the Lewis acid type comprising a member selected from the group consisting of SO₂, NO₂, CO₂ and BF₃ etherate.

9. The method of claim 4 wherein said plasticizer comprises a member selected from the group consisting of dibutylphthalate, dioctylphthalate, diisononylphthalate, dioctyladipate and triacetin.

10. 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.

11. 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.

12. The kit of claim 11 further comprising a catalyst to promote the polymerization of said cyanoacrylate ester monomer.

13. 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.

14. 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.

15. 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.

16. 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.

17. The kit of claim 14 wherein said stabilizer comprises a hydroquinone.

18. The kit of claim 14 wherein said inhibitor is of the Lewis acid type comprising a member selected from the group consisting of SO₂, NO₂, CO₂ and BF₃ etherate.

19. The kit of claim 14 wherein said plasticizer comprises a member selected from the group consisting of dibutylphthalate, dioctylphthalate, diisononylphthalate, dioctyladipate and triacetin.
