Abstract

A mixing system and method for forming bone cement by mixing liquid monomer methyl methacrylate (MMA) with a powder component comprising polymethyl methacrylate (PMMA). A container of MMA is received in a bag. The MMA is emptied from the container into the bag, and a syringe is connected to the bag in substantially leak-free manner to receive the MMA from the bag. The syringe is disconnected from the bag and thereafter connected to a receptacle housing the powder component. The MMA is then transferred into the receptacle in substantially leak-free manner.

Claims (19)

1. A mixing system for mixing a hazardous substance with one or more additional components to form a product, the mixing system comprising:

a bag, said bag being sized for receiving a container of said hazardous substance and structured for housing said hazardous substance from said container in a substantially leak-free manner, said bag including a bag connector;

a syringe, said syringe including a syringe connector configured to mate with the bag connector to form a substantially leak-free seal therebetween, said syringe sized and adapted for receiving said hazardous substance from said bag; and

a receptacle, said receptacle including a receptacle connector configured to mate with said syringe connector to form a substantially leak-free seal therebetween, said receptacle sized for housing said one or more additional components and for receiving said hazardous substance from said syringe for mixing with the one or more additional components to form the product.

2. The mixing system of claim 1 , wherein said bag comprises a filter member.

3. The mixing system of claim 2 , wherein said bag comprises a sealing mechanism, said sealing mechanism being selectively sealable for allowing access into said bag.

4. The mixing system of claim 3 , wherein said sealing mechanism comprises at least one of a rib and groove fastener, a hook and loop fastener, and a zipper.

5. The mixing system of claim 3 , wherein said sealing mechanism comprises a rib and groove fastener.

6. The mixing system of claim 1 , wherein said bag comprises a polymeric material selected from the group consisting of polyethylene, polyimide, silicone, polyester, polyetherimide, PVC, polyurethane, nylon, and copolymers thereof.

7. The mixing system of claim 1 , wherein said syringe connector and bag connector comprise mating luer lock connectors.

8. The mixing system of claim 1 , wherein said syringe connector and receptacle connector comprise mating luer lock connectors.

9. The mixing system of claim 1 , wherein said receptacle further comprises a removable lid.

10. The mixing system of claim 1 , wherein said receptacle further comprises a base portion.

11. A mixing system for mixing a hazardous substance with one or more additional components to form a product, the mixing system comprising:

a bag, said bag including a bag connector, said bag sized for receiving a container of said hazardous substance therein; and

a receptacle for receiving said hazardous substance from said bag, said receptacle including a receptacle connector configured to mate with said bag connector to form a substantially leak-free seal therebetween, said receptacle sized for retaining said one or more additional components therein and for receiving said hazardous substance to form the product.

12. The mixing system of claim 11 , wherein said bag comprises a filter member.

13. The mixing system of claim 11 , wherein said bag comprises a sealing mechanism, said sealing mechanism comprising at least one of a rib and groove fastener, a hook and loop fastener, a zipper and an adhesive.

14. The mixing system of claim 12 , wherein said bag comprises a polymeric material selected from the group consisting of polyethylene, polyimide, silicone, polyester, polyetherimide, PVC, polyurethane, nylon, and copolymers thereof, and said receptacle comprises a polymeric material selected from the group consisting of polyethylene, polypropylene and polyethylene terephthalate.
